1 Introduction to AT Commands This manual lists detailed information on the function of the AT Command set that can be used with the PC300 or EM400. This manual refers to the PC300 and EM400 as radio devices. If there is a difference in the functionality of the radio devices PC300 and EM400, information will be listed separately.

1.1 Related Documentation This manual is supplied with an Integrator’s Manual when you purchase a PC300 or EM400.

1.2 Overview AT commands, issued from a computer in your application are used to control and implement the functions of the module. Using AT commands, the following actions are possible: •Control of DCE •GPRS •Call control •Supplementary Service •SIM application tool kit •Control any embedded application in the device The manual contains a large number of Sony Ericsson-specific commands in addition to those implemented in accordance with the 3GPP and ITU-T recommendations. These commands are provided to enhance the functions of the module. The Sony Ericsson-specific commands are identified by the asterisk that precedes the command (see the syntax description provided below). Only commands that are listed in the AT Commands Manual are supported unless otherwise stated. Other commands may be supported by the module but these are only included for historical or legacy reasons.

1.3 History of Core Module AT Commands Manuals The following table describes the module software version documented in each AT Command Manual version.

AT Manual Version Product Firmware Revision

PA1 R1A025

PA3 R1A039

1.4 Syntax Description This section provides a brief description of the syntax used for the PC300 AT command set. See the ITU-T recommendation V.25ter for additional information.


Page 10 of 272

1.4.1 Conventions In this manual, the following conventions are used to explain the AT commands. <command> The name of the command that is to be entered. <parameter> The parameter values that are defined for a certain command. <CR> The command line is terminated by the Carriage Return (or Enter key) or ATS3 command. <LF> Line feed character or ATS4 command. < > The term enclosed in angle brackets is a syntactical element. The brackets do not appear in the command line. [ ] Square brackets are used to indicate that a certain item is optional. For example, sub-parameters of a command or an optional part of a response. The brackets do not appear in the command line. <Value> The default values of the supported parameters are indicated by using bold text when presenting the value. •Other characters, including ‘?', parenthesis, etc., appear in commands and responses as written. •The final result codes OK, ERROR, +CME ERROR: <err> and CMS ERROR:<err> (see sections 1.3.3 AT Response Syntax and 1.4 Error Codes) are not listed under “Possible Responses” for each AT command. •OK and ERROR are listed if these are the only possible responses.

1.4.2 AT Command Syntax The AT standard is a line-oriented command language. Each command is made up of the following three elements: •the prefix; •the body; •the termination character. The prefix consists of the letters “AT” or "at", or , to repeat the execution of the previous command line, the characters "A/" or "a/". The body is made up of the command, the parameter, and if applicable the associated values. Commands may be combined in the same command line. Spaces between the individual bodies are ignored.

Basic Syntax Command The format of basic syntax commands is as follows: AT<command>[=][<parameter>]<CR> ATS0=0<CR> (sets the automatic answering) Additional commands may follow a command on the same command line without any character being required for separation. For the command D parameters, see the description for the command in question. A version of the basic syntax is:


Page 11 of 272

AT<command><parameter>

Extended Syntax Command •AT+<command>= [<parameter>] •AT*<command>=[<parameter>] AT+CFUN=0<CR> (powers down the module) If several values are included in the command, they are separated by commas. It is also possible to enter commands with no values. Additional commands may follow an extended syntax command on the same command line if a semicolon (; IRA 3B) is inserted after the preceding extended command as a separator.

Read Command Syntax The read command is used to check the current values of parameters. Type ‘?’, after the command line: •AT+<command>? •AT*<command>? •AT<command>? AT+CSCS?<CR> (show current character set) <CR>“IRA”<CR> (information text response) <CR>OK<CR>(final result code response)

Test Command Syntax The test command is used to test whether the command has been implemented or to give information about the type of subparameters it contains. Type ‘?’, after the command line: •AT+<command>=? •AT*<command>=? AT+CPAS=?<CR> (shows supported values for the response parameters) <CR>CPAS: (0, 3, 4, 129, 130, 131)<CR> (supported values) <CR>OK<CR> (final result code) If the indicated <parameter> is not recognized, the result code ERROR is issued. Possible responses are indicated both as <command>:(list of supported<parameter>) and (in most cases) the actual range of the parameter values.

1.4.3 Other Terminology In this document, terms “alternating mode” and “alternating call” refer to all GSM bearer and teleservices that incorporate more than one basic service (voice, data, fax) within one call.

1.4.4 AT Response Syntax The default mode response shown below is in text mode. For information about the ATV DCE response, see ATV DCE Response Format. Possible formats for the result codes are: •Basic format result code, such as OK. The Basic result code also has a numerical equivalent.


Page 12 of 272

•Extended format result code, prefixed with a plus sign (+) or an asterisk (*):

•AT+<command>: <parameter > •AT*<command>: <parameter>

where the <parameter> is the result code value, note that a single space character separates the colon character from the <parameter>. If several values are included in the result code, they are separated by commas. It is also possible that a result code has no value. The extended syntax result codes have no numerical equivalent. They are always issued in alphabetical form. •Information text response may contain multiple lines separated by <CR>. The TE detects the end of informational text responses by looking for a final result code response, such as OK. There are two types of result code responses as outlined below:

Final Result Code A final result code indicates to the TE that execution of the command is completed and another command may be issued. •If you type an implemented AT command, you should get the result code OK. •If you type an AT command that is not implemented, or which had the wrong parameter or syntax, you will get an error result code. It is ERROR or, for example, +<command> ERROR followed by an error code. Final result codes are: Value General meaning OK Command executed, no errors ERROR Invalid command or command line too long NO DIALTONE No dialing possible, wrong mode BUSY Remote station busy NO ANSWER Connection completion time-out NO CARRIER Link not established or disconnected

Unsolicited Result Code Unsolicited result codes indicate the occurrence of an event not directly associated with a command being issued from the TE.

1.5 Examples on How to Use the AT Commands For many of the more complicated commands, examples are provided after the command’s description. Always refer to the detailed description of the command in question to check valid parameter values, AT command syntax and Response syntax.

1.6 GPRS Communication To initiate a session with the network you need to set up a ‘data account’ on the module using the AT+CGDCONT command. You need to specify the correct Access Point Name (APN) which you get from your service provider. The command below sets up the data account to access an APN called "internet."


Page 13 of 272

AT+CGDCONT=1,“IP”,“internet” After this you need to use the ATD command to make a GPRS call. The example below dials into the network using account number 1. ATD*99***1# If the module is able to connect to the APN it will return a CONNECT. At this point PPP/IP packets should be sent by the application, to negotiate an IP address. The easiest way of doing this whole thing is to create a windows dial up networking session with the dial string *99***1# after creating the data account on the module. It is not possible to initiate a GPRS session from the network at present. The reason for this is that unless a PDP context has been setup it has not been assigned an IP address by the GGSN/DHCP server and as a result it cannot be addressed other than through its ME number (defeating the object of using IP). This is specified in GSM 7.60 or 3GPP 27.060. For additional information about GPRS communication, refer to the application note, which can be obtained from the extranet or from customer support.

1.7 Abortability Commands that are able to be stopped or terminated while executing are said to be "abortable". These abortable commands may be terminated by sending a character or control sequence. As very few commands are abortable - all AT-Commands in this manual should be considered "not abortable" unless otherwise noted. This command is abortable. The following commands can be aborted: AT&W Store Configuration Profile AT*E2CMGL List Message without marking Read AT+CCFC Call Forwarding number and Conditions AT+CCWA Call Waiting AT+CGACT PCP Context Activate AT+CGATT GPRS Attach or Detach AT+CLAC List AT Commands AT+CLCK Facility Lock AT+CLIP Calling Line Identification AT+CLIR Calling Line Identification Restriction AT+CMGC Send Command AT+CMGS Send Message AT+CMGW Write Message to Memory AT+CMSS Send Storage AT+CNUM Subscriber Number AT+COLP Connected Line Presentation AT+COPN Read Operator Names AT+CPOL Preferred Operator List

2 Call Control

2.1 ATA Answer Incoming Call

Description Command Possible Responses

Answer an incoming call ATA CONNECT

CONNECT <text>

NO CARRIER

ERROR

OK Description: The command instructs the MS to answer immediately if an incoming call is pending. The behaviour is different depending on the type of incoming call as reflected in the table below. Note 1: If a test command (ATA=?) is issued, the response will be NO CARRIER as this will be interpreted as ATA command.

This command is abortable. Defined values: <text> Description

4800 Connected with data bit rate of 4800 bits/s




xx (other values may appear due to functionality)

Example: RING RING ATA OK

2.2 ATD Dial Command syntax: The dial command includes a number of dial modifiers and parameters that influence both the behaviour and the result codes. As a consequence of that the description table includes a number of typical


Page 16 of 272

combinations for better understanding compared to writing the command with all parameters and dial modifiers presented as one line as in most other commands.


Originate a call and dial the phone number specified in <dial_string>.

ATD<dial_string>[G or g][I or i][;]

CONNECT CONNECT <text> NO CARRIER NO DIALTONE BUSY

No action commands that returns result codes immediately.

ATD[;] OK (If semicolon included) NO CARRIER (If semicolon not included)

Dial the phone number stored in memory location <mem> with index <n>. If <mem> is omitted, the memory storage is defined by the +CPBS command.

ATD>[<mem>]<n>[G or g][I or i][;]

CONNECT CONNECT <text> NO CARRIER NO DIAL TONE BUSY

Dial the phone number that corresponds with alphanumeric field in <str>

ATD><str>[G or g][I or i][;]

CONNECT CONNECT <text> NO CARRIER NO DIAL TONE BUSY

Redial the latest phone number dialled. Note that in case of multiplexer, e.g. 27.010 this command will send the latest dialled number

ATDL[G or g][I or i][;] CONNECT CONNECT <text> NO CARRIER NO DIAL


Page 17 of 272


on the same channel as the ATDL command. This in contrast to the ATD>LD command, which will send the latest dialled number in total.

TONE BUSY

Description: This command instructs the MS to originate a call, which may be data or voice. The phone number used to establish the connection will consist of digits and modifiers included in <dial_string> or a stored number specified by the <mem>, <n> or <str> parameters, or dial modifier L. This allows for dialling from phonebook locations based on index or an alphanumeric field that identifies an entry in phonebook as well as from other <mem> storages such as Last Dialled Numbers (LD). Command Select Phonebook Memory Storage (+CPBS) is recommended to be used to select memory storage. Note! Only ME and SM memory storage are supported by ATD. If the dial string is followed by a semicolon this informs the phone that the number is a voice call rather than a data number. Dial command terminated by semicolon shall always give OK as terminating result code. Note: Other commands added in the same string after the ATD command are ignored. Aborting an ATD command is accomplished by the transmission from the DTE to the DCE of any character. A single character shall be sufficient to abort the command in progress; however, characters transmitted during the first 125 milliseconds after transmission of the termination character are ignored. This is to allow the DTE to append additional control characters such as line feed after the command line termination character.

Defined values:

<dial_string> Description

“0 1 2 3 4 5 6 7 8 9 * # + A B C”

Valid characters for origination

D This character is a part of V.25ter, but is here only included for compatibility reasons, no code is transmitted for this character.

W The W modifier is ignored but is included for compatibility reasons.

' The comma modifier is ignored but is included for compatibility reasons.

T The T modifier is ignored but is included for compatibility reasons.

P The P modifier is ignored but is included for

command is supported Description:

This command causes the ME to perform whatever actions are necessary to establish communication between the TE and the external Packet Data Network. The V.25ter 'D' (Dial) command causes the ME to enter the V.25ter online data state and, with the TE, to start the specified layer 2 protocol. The ME shall return CONNECT to confirm acceptance of the command prior to entering the V.25ter online data state. No further commands may follow on the AT command line. The detailed behaviour after the online data state has been entered is dependent on the PDP type. It is described briefly in clause 9 (for IP) of 3GPP TS 27.060. PS attachment and PDP context activation procedures may take place prior to or during the PDP startup if they have not already been performed using the +CGATT and +CGACT commands. When the layer 2 protocol has terminated, either as a result of an orderly shut down of the PDP or an error, the ME enters V.25ter command state and return the NO CARRIER final result code. The usage of <cid> is the same as in the +CGDATA command. The +CGDCONT, +CGQREQ, etc. commands may then be used in the modem initialisation AT command string to set values for for PDP type, APN, QoS etc.. If <cid> is omitted, the ME shall attempt to activate the context using: (a) any information provided by the TE during the PDP startup procedure, e.g. the TE may provide a PDP type and/or PDP address to the ME, (b) a priori knowledge, e.g. the ME may implement only one PDP type (c) using the 'Empty PDP type' (3GPP TS 24.008). (No PDP address or APN shall be sent in this case and only one PDP context subscription record shall be present in the HLR for this subscriber.) This command may be used in both normal and modem compatibility modes. NOTE: The dial string conforms to the syntax specified in 3GPP TS 22.030

Defined Values:

<GPRS/Packet_Domain SC_IP>

ERROR


AT+CIND=? +CIND: (<descr>,(list of supported <ind>s)), (<descr>,(list of supported <ind>s)),…

+CME ERROR: <err>

OK

ERROR Description:

This command shows the values of ME indicators. <ind> value 0 means that the indicator is off (or in a state which can be identified as “off” state), 1 means that indicator is on (or in a state which is more substantial than “off” state), 2 is more substantial than 1, and so on. If the indicator is a simple on/off style element, it has values 0 and 1. The list of <ind>s is returned as an ordered list of values without identifiers - the position of each <ind> in the list must be determined by using the test command. The ME does not allow setting of indicators, ERROR is returned from the set command. Test command returns pairs, where string value <descr> is a maximum 16 character description of the indicator and compound value is the allowed values for the indicator. If ME is not currently reachable, +CME ERROR: <err> is returned (refer to 3GPP 27.007).

Notes: The indicator <descr>="signal" represents the relative signal level (e.g. number of "bars") for both GSM and WCDMA signals. This is the preferred method for obtaining signal level for both technology types. Note that +CSQ is available to obtain GSM signal levels only and an indicator mapping algorithm must be applied to the raw RSSI values returned by +CSQ, whereas +CIND may be used to obtain levels for both technology types. There is no method available for the TE to obtain the raw WCDMA signal values from the ME. The range of values reported in "signal" may vary by implementation. The default range is (0-5), however the test command should be used to determine the currently reported range. The maximum possible range of "signal" is (0-9). Indicators which apply only to phones and not to Data Card devices may appear in the test command results. Indicators listed below as (not applicable) may have reported values but are meaningless for a Data Card device.

Defined values:

4 Operational Control and Status

4.1 AT+CFUN Set Phone Functionality


Set MS functionality AT+CFUN=<fun> +CME ERROR: <err>

OK


AT+CFUN? +CFUN: <fun>

+CME ERROR: <err>


AT+CFUN=? +CFUN: (list of supported <fun>s)

+CME ERROR: <err>

Description: This command selects the level of functionality <fun> in the MS. Level “full functionality” results in the highest level of power drawn. “Minimum functionality” results in the minimum power drawn. This command may also be used to restrict the supported Radio Access Technology (RAT) of the ME between GSM only or WCDMA only. Test command returns values supported by the ME.

Notes: Switching to Power Down mode <fun>=0, results in a complete power down of the ME, and it is then no longer responsive to further AT commands. The ME must be reset by removing and reinserting the device in order to reestablish control. For this reason, <fun>=0 should never be used with an internal minicard ME unless the host system is shutting down and power to the card slot is guaranteed to be cycled. In order to set the ME to minimal functionality and still retain the ability for further software control, <fun>=4 should be used. For PCI Express mini card products, note that the W_Disable_N input signal will also have an effect on the CFUN state, and the allowed CFUN values. When this signal prevents turning on the radio with <fun>=1, 5, or 6, a specific CME ERROR (WAN Disabled on Host) will be returned to indicate this failure cause.

Defined values:

<fun> Description

0 Power down.


Page 54 of 272

<fun> Description

1 Full functionality

2 Not supported

3 Not supported

4 Disable transmit and receive RF circuits. SIM still enabled. This is often referred to as "flight mode."

5 GSM only (WCDMA radio is off)

6 WCDMA only (GSM radio is off)

4.2 AT*E2RESET Restart Module


Perform a restart of the device firmware

AT*E2RESET OK

ERROR


AT*E2RESET=? OK

ERROR Description:

This command is used to cause the module to reset and restart. The software internally will allow a watch dog timeout to occur which will reset the microcontroller’s internal registers and restart the software at the beginning of operation. Most blocks internal to the module will be reset and reinitialized. All settings and levels set by previous AT commands that are not stored in non-volatile memory will have to be reissued. The general result of this command is to return as much of the system back to normal power on conditions. The power state will be returned to CFUN=4 after the reset. This command is available without SIM access. Note: The proper radio access operations as defined by 3GPP will be performed prior to the reset. e.g. if the device is GPRS attached and registered then a detach and power-down registration will be performed.

4.3 AT+CMAR Master Reset

ERROR Description:

Used to activate or deactivate the specified PDP context(s). Before a context may be activated it must be defined by the command AT+CGDCONT. If a context is not already attached to the GPRS network then this command will automatically attach before attempting the activation. After the command has completed, the MS remains in V.250 command state. If the MS is already in the requested state, the command is ignored and OK is returned. If the requested state cannot be achieved, ERROR or +CME ERROR is returned. If the MS is not attached to the GPRS service when the activation form of the command is executed, the MS first performs a GPRS attach and then attempts to activate the specific contexts. If no <cid>s are specified, then the activation form of the command activates all defined contexts and the deactivation form of the command deactivates all active contexts.

If the requested modification for any specified context cannot be achieved, an ERROR or +CME ERROR response is returned. Extended error responses are enabled by the +CMEE command. If no <cid>s are specified, the activation form of the command modifies all active contexts. The test command returns a list of <cid>s associated with active contexts.

ERROR Description:

Used to attach the MS to, or detach the MS from, the GPRS/packet domain service. After the command has completed, the MS remains in V.250 command state. If the MS is already in the requested state, the command is ignored and the OK response is returned. If the requested state cannot be achieved, an ERROR or +CME ERROR response is returned. Extended error responses (enabled by the +CMEE command) are listed under “+CME ERROR (Mobile Equipment Error Code)”. Any active PDP contexts will be automatically deactivated when the attachment state changes to detached. Note: The unit software is automatically hard coded to attach to a GPRS network therefore entering this command as part of the initialization sequence is not required. Note: This command has the characteristics of both the V.250 action and parameter commands. Hence it has the read form in addition to the execution/set and test forms.

During each PDP startup procedure the ME may have access to some or all of the following information - · The command may have provided an <L2P> parameter value. · The TE may provide a PDP type and/or PDP address to the ME during in the PDP startup procedure. If any of this information is in conflict, the command will fail. Any PDP type and/or PDP address present in the above information are compared with the PDP type and/or PDP address in any context definitions specified in the command in the order in which their <cid>s appear. For a context definition to match - · The PDP type must match exactly. · The PDP addresses are considered to match if they are identical or if either or both addresses are unspecified. For example, a PPP NCP request specifying PDP type = IP and no PDP address would cause the ME to search through the specified context definitions for one with PDP type = IP and any PDP address. The context shall be activated using the matched value for PDP type and a static PDP address if available, together with the other information found in the PDP context definition. If a static PDP address is not available then a dynamic address is requested. If no <cid> is given or if there is no matching context definition, the ME shall attempt to activate the context with whatever information is available to the ME. The other context parameters shall be set to their default values. If the activation is successful, data transfer may proceed. After data transfer is complete, and the layer 2 protocol termination procedure has completed successfully, the V.25ter command state is re-entered and the ME returns the final result code OK. In the event of an erroneous termination or a failure to start up, the V.25ter command state is re-entered and the ME returns the final result code NO CARRIER or, if enabled, +CME ERROR. Attach, activate and other errors may be reported.

[…]] Description

This command allows the TE to specify a minimum acceptable profile, which is checked by the MT against the negotiated profile returned in the Activate/Modify PDP Context Accept message. The set command specifies a profile for the context identified by the (local) context identification parameter, <cid>. The specified profile will be stored in the MT and checked against the negotiated profile only at activation or MS-initiated modification of the related context. Since this is the same parameter that is used in the +CGDCONT and +GGDSCONT commands, the +CGEQMIN command is effectively an extension to these commands. The QoS profile consists of a number of parameters, each of which may be set to a separate value. A special form of the set command, +CGEQMIN= <cid> causes the minimum acceptable profile for context number <cid> to be returned to the default values. In this case no check is made against the negotiated profile. The read command returns the current settings for each defined context. The test command returns values supported as a compound value. The parameter value ranges for each PDP type are returned on a separate line. The QoS profiles for PDP contexts are part of the configuration profile. The default setting for every PDP context is an empty QoS profile. Executing AT&F restores the QoS profile for all PDP contexts to the empty profile. To commit the QoS profile for all PDP contexts to non-volatile memory, AT&W must be executed.

Defined values <cid> Description

See AT+CGDCONT for range of <cid>.

<Maximum bitrate UL> Description

Integer Maximum number of kbit/s delivered to UMTS. Ericsson Specific note: With reference to 3GPP TS 24.008 subclause 10.5.6.5, not all the integer values are valid. Thus upon setting this parameter, the value is rounded down to the nearest valid value. It then follows that reading back this parameter may produce a different value than that used upon setting.

[…]] Description

This command allows the TE to specify a UMTS Quality of Service Profile that is used when the MT sends an Activate PDP Context Request message to the network. The set command specifies a profile for the context identified by the (local) context identification parameter, <cid>. The specified profile will be stored in the MT and sent to the network only at activation or MS-initiated modification of the related context. Since this is the same parameter that is used in the +CGDCONT command, the +CGEQREQ command is effectively an extension to this command. The QoS profile consists of a number of parameters, each of which may be set to a separate value. A special form of the set command, +CGEQREQ= <cid> causes the requested profile for context number <cid> to reset to the default QoS values.. The read command returns the current settings for each defined context. The test command returns values supported as a compound value. If the MT supports several PDP types, the parameter value ranges for each PDP type are returned on a separate line. The QoS profiles for PDP contexts are part of the configuration profile. The default setting for every PDP context is an empty QoS profile. Executing AT&F restores the QoS profile for all PDP contexts to the empty profile. To commit the QoS profile for all PDP contexts to non-volatile memory, AT&W must be executed.

Defined values <cid>: a numeric parameter which specifies a particular PDP context definition (see +CGDCONT command). The following parameters are defined in 3GPP TS 23.107 -

If the Traffic class is specified as conversational or streaming, then the Guaranteed and Maximum bitrate parameters should also be provided. Other values are reserved.

<Maximum bitrate UL>: A numeric parameter that indicates the maximum number of kbits/s delivered to UMTS (up-link traffic) at a SAP. As an example, a bitrate of 32kbit/s would be specified as '32' (e.g. AT+CGEQREQ=...,32,...). This parameter should be provided if the Traffic class is specified as conversational or streaming. <Maximum bitrate DL>: A numeric parameter that indicates the maximum number of kbits/s delivered by UMTS (down-link traffic) at a SAP. As an example a bitrate of 32kbit/s would be specified as '32' (e.g. AT+CGEQREQ=...,32,...). If the parameter is set to '0' the subscribed value will be requested. This parameter should be provided if the Traffic class is specified as conversational or streaming. <Guaranteed bitrate UL>: A numeric parameter that indicates the guaranteed number of kbits/s delivered to UMTS (up-link traffic) at a SAP (provided that there is data to deliver). As an example a bitrate of 32kbit/s would be specified as '32' (e.g. AT+CGEQREQ=...,32,...). If the parameter is set to '0' the subscribed value will be requested. This parameter should be provided if the Traffic class is specified as conversational or streaming. <Guaranteed bitrate DL>: A numeric parameter that indicates the guaranteed number of kbits/s delivered by UMTS (down-link traffic) at a SAP (provided that there is data to deliver). As an example a bitrate of 32kbit/s would be specified as '32' (e.g. AT+CGEQREQ=...,32,...). If the parameter is set to '0' the subscribed value will be requested.

<Maximum SDU size>: A numeric parameter (1, 2, 3, …) that indicates the maximum allowed SDU size in octets. If the parameter is set to '0' the subscribed value will be requested. <SDU error ratio>: A string parameter that indicates the target value for the fraction of SDUs lost or detected as erroneous. SDU error ratio is defined only for conforming traffic. The value is specified as 'mEe'. As an example a target SDU error ratio of 5•10-3 would be specified as '5E3' (e.g. AT+CGEQREQ=...,"5E3",...). '0E0' means subscribed value. <Residual bit error ratio>: A string parameter that indicates the target value for the undetected bit error ratio in the delivered SDUs. If no error detection is requested, Residual bit error ratio indicates the bit error ratio in the delivered SDUs. The value is specified as 'mEe'. As an example a target residual bit error ratio of 5•10-3 would be specified as '5E3' (e.g. AT+CGEQREQ=...,"5E3",...). '0E0' means subscribed value. <Delivery of erroneous SDUs>: A numeric parameter that indicates whether SDUs detected as erroneous shall be delivered or not.

Other values are reserved. <Transfer delay>: A numeric parameter (0, 1, 2, …) that indicates the targeted time between request to transfer an SDU at one SAP to its delivery at the other SAP, in milliseconds. If the parameter is set to '0' the subscribed value will be requested. <Traffic handling priority>: A numeric parameter (1, 2, 3, …) that specifies the relative importance for handling of all SDUs belonging to the UMTS bearer compared to the SDUs of other bearers. If the parameter is set to '0' the subscribed value will be requested. <PDP_type>: (see +CGDCONT command). If a value is omitted for a particular class then the value is considered to be unspecified.

[…]] Description:

This command allows the TE to specify a Packet Filter - PF for a Traffic Flow Template - TFT that is used in the GGSN for routing of down-link packets onto different QoS flows towards the TE. The concept is further described in the 3GPP TS 23.060. A TFT consists of from one and up to eight Packet Filters, each identified by a unique <packet filter identifier>. A Packet Filter also has an <evaluation precedence index> that is unique within all TFTs associated with all PDP contexts that are associated with the same PDP address. The set command specifies a Packet Filter that is to be added to the TFT stored in the MT and used for the context identified by the (local) context identification parameter, <cid>. The specified TFT will be stored in the GGSN only at activation or MS-initiated modification of the related context. Since this is the same parameter that is used in the +CGDCONT and +CGDSCONT commands, the +CGTFT command is effectively an extension to these commands. The Packet Filters consist of a number of parameters, each of which may be set to a separate value. A special form of the set command, +CGTFT= <cid> causes all of the Packet Filters in the TFT for context number <cid> to become undefined. At any time there may exist only one PDP context with no associated TFT amongst all PDP contexts associated to one PDP address. At an attempt to delete a TFT, which would violate this rule, an ERROR or +CME ERROR response is returned. Extended error responses are enabled by the +CMEE command. The read command returns the current settings for all Packet Filters for each defined context. In case no filter is defined the read command will return "OK" only. The test command returns values supported as a compound value. If the MT supports several PDP types, the parameter value ranges for each PDP type are returned on a separate line. TFTs shall be used for PDP-type IP and PPP only. For PDP-type PPP a TFT is applicable only when IP traffic is carried over PPP. If PPP carries header-compressed IP packets, then a TFT cannot be used.

Defined values:

<cid>: a numeric parameter which specifies a particular PDP context definition (see the +CGDCONT and +CGDSCONT commands).


Page 108 of 272

The following parameters are defined in 3GPP TS 23.060 - <packet filter identifier>: Numeric parameter, value range from 1 to 8. <source address and subnet mask>: Consists of dot-separated numeric (0-255) parameters on the form 'a1.a2.a3.a4.m1.m2.m3.m4', for IPv4 and 'a1.a2.a3.a4.a5.a6.a7.a8.a9.a10.a11.a12.a13.a14.a15.a16. m1.m2.m3.m4.m5.m6.m7.m8.m9.m10.m11.m12.m13.m14.m15.m16', for IPv6. <protocol number (ipv4) / next header (ipv6)>: Numeric parameter, value range from 0 to 255. <destination port range>: String consisting of dot-separated numeric (0-65535) parameters on the form 'f.t'. <source port range>:String consisting of dot-separated numeric (0-65535) parameters on the form 'f.t'. <ipsec security parameter index (spi)>: Hexadecimal parameter, value range from 00000000 to FFFFFFFF. <type of service (tos) (ipv4) and mask / traffic class (ipv6) and mask>: Dot-separated numeric (0-255) parameters on the form 't.m'. <flow label (ipv6)>: Hexadecimal parameter, value range from 00000 to FFFFF. Valid for IPv6 only. <evaluation precedence index>: Numeric parameter, value range from 0 to 255. Some of the above listed attributes may coexist in a Packet Filter while others mutually exclude each other, the possible combinations are shown in 3GPP TS 23.060.

This command is used to enable or disable the USB Ethernet Emulation communication interface, and to associate a particular PDP Context with the interface. A PDP context is referenced which must have been previously defined via the *EIAC command or the +CGDCONT command. Also, an internet account must have been previously created and defined via the *EIAC command.

Additional Information: A response of OK does not mean that a connection has been established or disconnected. This simply means that the command has been processed without any errors. To check the status of the connection, use the check connection status command. (AT*ENAP?) When executing the command to create a USB Ethernet connection, the response will be ERROR if a connection already exists. When executing the command to disconnect a USB Ethernet connection, the response will be ERROR if no connection exists.

AT*EIAC=? Range of general parameters: *EIAC: (1-4),("")

Description: This command is used to define the general parameters of an Internet Account (IA). When a new account is defined it is assigned an index which is subsequently returned as an informational text response together with bearer type and name of account. When using the IA configuration command, one can not force the value of the index. The other Internet Account commands can not be used to create an account. The other AT commands have to indicate the index value of an existing Account in combination with what kind of bearer the parameters are set for. The exception is the Internet Account configuration commands where it is implicit what the bearer type is (e.g. AT*EIAPSW - write PS bearer parameters), then only index value is necessary. Note! When a PDP Context is defined via an AT command, an Internet Account is automatically created with Packet Domain Service as the bearer and it get's an index value with a one-to-one mapping to the specified <cid> parameter value of the GPRS command. If the IA with that mapping to CId value is already existing, the specific parameters of that IA is overwritten (also when IA parameters are originally specified for another bearer than PS). In the same way a PDP Context with the default values set is defined when an IA is created with Packet Domain Service as the bearer, using the AT*EIAC command. The <cid> of the PDP context will have a one-to-one mapping with the PS bearer IA's index. Note! If user does not specify any bearer type, the command results in an error response. Note! If user does not specify a name of the account, an autogenerated name will be added to the account. Note! The temporary or locked type of accounts are reserved for internal

The command is used to specify the IP addresses to be used, both under PPP negotiations as well as under PS network connection establishment (context activation). If "0" values are given necessary parameters are requested to be genereated dynamically by the network one attaches to. If specific values are set, it means requesting for static IP addresses to be used. Note! Values stored here are not the ones used when doing PS dial-up connection from external application (TE), since TE in this case has it's own IP addresses to negotiate with the network (what TE sends is forwarded by ME's PPP proxy to network).

ERROR Description:

This command is used to edit the PLMN selector with Access Technology lists in the SIM card or active application in the UICC(GSM or USIM).


Page 174 of 272

Execute command writes an entry in the SIM/USIM list of preferred PLMNs, which could previously have been selected by the command +CPLS, however, as this command is not supported, the User controlled PLMN selector with Access Technology, EFPLMNwAcT, is the one accessed by default. If <index> is given but <oper> is left out, entry is deleted. If <oper> is given but <index> is left out, <oper> is put in the next free location. If only <format> is given, the format of the <oper> in the read command is changed. The Access Technology selection parameters, <GSM_AcT>, <GSM_Compact_AcT> and <UTRAN_AcT>, are required when writing User controlled PLMN selector with Access Technology, EF EFPLMNwAcT, If <index> is given but <oper> is left out, entry is deleted. If <oper> is given but <index> is left out, <oper> is put in the next free location. If only <format> is given, the format of the <oper> in the read command is changed Note: ME may also update this list automatically when new networks are selected. Note: AcT parameters are optional for the set command, but if one of the parameters is issued then all should be issued.If the parameters are not issued at all or only indicated by commas then the respective default values 1,0,1 are used. Read command returns all used entries from the SIM list of preferred operators. Test command returns the whole index range supported by the SIM. Note: While the +CPLS command is not supported, this +CPOL command will behave as though +CPLS is set to value 0. Thus, per TS27.007, this behavior is "User controlled PLMN selector with Access Technology EFPLMNwAcT, if not found in the SIM/UICC then PLMN preferred list EFPLMNsel (this file is only available in SIM card or GSM application selected in UICC)"

16 SIM Commands

16.1 AT+CRSM Restricted SIM Access


Transmit command

AT+CRSM=<command>[,<fileid>[, <P1>,<P2>,<P3>[,<data>[,<pathid>]]]]

+CRSM: <sw1>,<sw2>[,<response>]

+CME ERROR: <err>


AT+CRSM=? OK

Description: By using this command instead of Generic SIM Access +CSIM TE application has easier but more limited access to the SIM database. This command transmits to the MT the SIM <command> and its required parameters. MT handles internally all SIM-MT interface locking and file selection routines. As response to the command, MT sends the actual SIM information parameters and response data. MT error result code +CME ERROR may be returned when the command cannot be passed to the SIM, but failure in the execution of the command in the SIM is reported in <sw1> and <sw2> parameters. The TE should be aware of the precedence of the GSM/UMTS application commands internal to the MT over the commands issued by the TE.

Additional Information: When accessing a SIM/USIM some <fileid> values are common between the different directory paths. In order to unambiguously specify which common <fileid> is intended the command *ECDF must first be used to select the active directory path to be used by +CRSM. Note that the *ECDF command effectively sets the active directory for all subsequent +CRSM use. Even if an EF can be uniquely identified by its <fileid> alone, if the correct directory has not been selected by *ECDF then the file will not be accessible.

The GET RESPONSE command return data which gives information about the current elementary datafield. This information includes the type of file and its size (refer to 3GPP 51.011)

After the READ BINARY or READ RECORD command, the requested data will be returned

A <response> is not returned after a successful UPDATE BINARY or UPDATE RECORD command

Command Help The AT+CRSM description in the 27.007 spec only shows the general syntax, and refers the reader to other specs for specific SIM/USIM commands. Here are a few specific examples. READ BINARY: AT+CRSM=176,<fileid>,<OffsetHi>,<OffsetLo>,<Len> UPDATE BINARY: AT+CRSM=214,<fileid>,<OffsetHi>,<OffsetLo>,<Len>,"<data>" READ RECORD: AT+CRSM=178,<fileid>,<RecNum>,<mode>,<RecLen> UPDATE RECORD: AT+CRSM=220,<fileid>,<RecNum>,<mode>,<RecLen>,"<data>"

Parameters: <fileid> Must be entered in decimal <RecNum> Record number, starting at record 1. <mode> 2=Next record. <RecNum> must be 0. 3=Previous. <RecNum> must be 0. 4=Absolute. If <RecNum> = 0, then Current record. <Len> Length of file, in bytes. <RecLen> Length of record, in bytes. <data> Hex data, two hex digits per byte.

If the targeted application on the UICC does support the requested EAP method, the MT shall use the value provided in <DFeap>, and it shall transmit the <EAP_packet_data> to the UICC application using the Authenticate APDU command as defined in ETSI TS 102 310. The appropriate DFEAP in the ADF must be selected prior to the submission of an EAP Authenticate command with the <EAP packet data>. Then the EAP Response data sent by the UICC


Page 222 of 272

application in its response to the Authenticate command shall be provided to the TE in <EAP_packet_resp>. If the targeted application on the UICC does not support the requested EAP method and if the MT does support this method then the <EAP packet data> shall be handled by the MT. During the handling of the EAP method, the MT shall run the authentication algorithm on the SIM or USIM, respectively. Also the MT has to allocate an <EAPsessionid> in order to identify an EAP session and its corresponding keys and parameters. If neither the MT nor the appropriate UICC application support the requested EAP method, the MT shall respond with CME ERROR: 49, (EAP method not supported).

Additional Information Note that this implementation supports only UICC handling of EAP methods.

ERROR Description:

This command refers to CLIR-service according to 3GPP TS 22.081 that allows a calling subscriber to enable or disable the presentation of the CLI to the called party when originating a call. Set command overrides the CLIR subscription (default is restricted or allowed) when temporary mode is provisioned as a default adjustment for all following outgoing calls. Using the opposite command can revoke this adjustment. If this command is used by a

subscriber without provision of CLIR in permanent mode the network will act according 3GPP TS 22.081. The setting shall be per logical channel. Set command directly writes to non-volatile memory so that the setting is preserved also after turning off/on the MS. The &F command will not affect the setting. Read command gives the default adjustment for all outgoing calls (given in <n>), and also triggers an interrogation of the provision status of the CLIR service (given in <m>). Test command returns values supported by the TA as a compound value. This command is not abortable.

ERROR Description:

This command allows control of the Unstructured Supplementary Service Data (USSD) according to 3GPP TS 22.090. Both network and mobile initiated operations are supported. Parameter <n> is used to disable/enable the presentation of an unsolicited result code (USSD response from the network, or network initiated operation) +CUSD: <m>[,<str>,<dcs>] to the TE. In addition, value <n>=2 is used to cancel an ongoing USSD session. If <n> is not given then the default value 0 is taken. When <str> is given, a mobile initiated USSD string or a response USSD string to a network initiated operation is sent to the network. The response USSD string from the network is returned in a subsequent unsolicited +CUSD: result code. The interaction of this command with other commands based on other GSM supplementary services is described in the GSM standard. Test command returns values supported by the TA as a compound value. Some different scenarios are shown below: 1. An incoming network initiated USSD-Notify should be presented to the external application as an unsolicited result code +CUSD: if the external application has enabled result code presentation. 2. An incoming USSD-request asking for a reply should sent to the external application as an unsolicited result code +CUSD: if the external application has enabled result code. 3. If the external application answers to the request with the command AT+CUSD then the ME sends the answer to the network.
