1.1 Huawei USC SolutionAt present, the service data of subscribers is distributed in different functional entities in thenetwork, and the functional entities have different data management modes. Isolated information"islands" thus emerge. The isolated information "islands" lack scalability, making the carriers'networks very complicated. In addition, it is hard for carriers to make use of the isolatedinformation to develop value-added services. As a result, carriers are facing more challenges inproviding the same service experience to subscribers over multiple types of networks.

Nowadays, more and more carriers come to realize the importance of convergence andcentralized management of the subscriber service data, and put forward various solutions. Torealize the subscriber-oriented convergence of subscriber service data becomes a developmenttrend in the telecommunication industry.

Huawei Unified Subscriber Center (USC) solution incorporates the network entities (NEs) suchas the Home Location Register (HLR), Home Subscriber Server (HSS), Authentication,Authorization and Accounting (AAA), Mobile Number Portability (MNP), Equipment IdentityRegister (EIR), and General User Profile (GUP). It can integrate the subscriber service datarequired by the NEs in the public land mobile network (PLMN), public switched telephonenetwork (PSTN), broadband network, and multimedia network.

The USC can realize centralized management of the subscriber service data and provide an opendata interface. It can simplify network deployment, accelerate the provisioning of new services,and prompt service innovation. The USC solution helps carriers to provide competitiveintegrated services.

1.4.1 Distributed Structure

The distributed structure allows multiple functional entities that are identical in a system to workin load-sharing mode to accomplish a certain function. The most distinguished feature of thedistributed structure is resource sharing in the system. When any functional entity fails, the loadwill be automatically switched over to other functional entities. Thus, the service provisioningof the whole system is not adversely affected.

Figure 1-4 shows the distributed structure.


Product Description


Issue 01 (2008-07-10)

Figure 1-4 Distributed structure

NMS: network management system BAM: Back Administration Module BE: Back End

BOSS: Business and Operation Support System SMU: Subscriber Management Unit FE: Front End

The HLR9820 consists of five logical layers: signaling processing layer, subscriber datamanagement layer, data service layer, data storage layer, and O&M layer. Each layer adoptsdistributed processing. Thus, the whole system features a fully-distributed structure.

The fully-distributed structure endues the HLR9820 with the following advantages:

l High reliabilityWhen any functional entity fails, the load is automatically switched over to other functionalentities. Thus, the service provisioning of the whole system is not adversely affected.

l Smooth expansionDuring system expansion, only the related functional entities need to be added. Afterdetecting that the newly added functional entities are running stably, the systemautomatically distributes the load evenly. Thus, the service provisioning of the system isnot adversely affected during the system expansion.

1.4.2 ATCA-Compatible OSTA 2.0 Hardware PlatformThe HLR9820 adopts the ATCA-compatible OSTA 2.0 hardware platform.

Composed of a series of PCI Industrial Computer Manufacturers Group (PICMG3.X)specifications, the ATCA standards are widely accepted as the standards for the next-generation,standard telecommunication hardware platforms.

The OSTA 2.0 platform adopts the Intel Architecture (IA), which allows the high-performanceand low-consumption processor, and the Carrier Grade Linux (CGL) technology. It is a highlycompetitive server provided by Huawei for telecommunication and IT markets.



1-9

In addition to complying with the ATCA standards, the OSTA 2.0 platform enjoys the followingadvantages:

l The whole equipment and monitoring equipment comply with the carrier-class applicationdesign.

l The service plane, control plane, and management plane are physically separated.

Thus, the lower-layer hardware planes are not adversely affected by other planes. Whenthe hardware needs to be upgraded, the software can still be used without any modification.Thus, the system reliability is greatly improved.

l The devices used in the OSTA 2.0 platform comply with the device selection specificationsfor carrier-class equipment and the ETSI/NEBS standards.

l The system is enhanced with the monitoring on equipment running, hardware components,and external interfaces, and added with the fault diagnosis mechanism and pre-alert for thesubhealth status.

l The OSTA 2.0 platform meets the anti-noise requirements and heat dissipationrequirements for carrier-class equipment.

l The OSTA 2.0 platform adopts automatic fault detection and fault isolation technologies.Thus, the fault detected can be isolated and will not adversely affect the running of otherparts.

l The perfect fault location design allows accurate identification of the faulty device.

1.4.3 Memory Data Management TechnologyThe memory manages all the subscriber data stored in the HLR9820. The board memoryaccomplishes the data query and data modification related to service processing. The externalstorage device (such as the disk array) of boards only provides permanent storage of data. It isindependent of service processing.

The memory data management endues the HLR9820 the following advantages:

l The service processing is independent of the external data storage device of boards.

If the external data storage device of boards fails, the service processing will not beadversely affected.

l Compared with the data management in hard disks, the memory data management featureshigher throughput and shorter time delay. It greatly enhances the system performance,especially for the large-capacity HLR.

1.4.4 Multi-Level Data Backup Mechanism

The HLR9820 adopts the multi-level data backup mechanism. The multi-level data backupmechanism enables subscriber data to be stored in different physical data storage devices,ensuring the security of subscriber data.

The multi-level data backup comprises:

l Level-1 backup

The subscriber data is stored in the memories of different boards. Multiple boards form acluster. The data of the master node is synchronized to the slave node.

l Level-2 backup


Product Description


Issue 01 (2008-07-10)

The subscriber data stored in the board memory is backed up to the local hard disk of theboard. Two local hard disks work in RAID 1 mode.

l Level-3 backup

The subscriber data stored in the board memory is backed up to the disk array. The diskarray has nine hard disks working in RAID 5+1. Hot spare disks are configured for the harddisks of the disk array.

1.4.5 Virtual HLR Function

The virtual HLR function allows a physical HLR to be divided into several logical HLRs. Eachlogical HLR is equivalent to the HLR in the local network.

The virtual HLR function enables the local networks in different areas to share the same physicalHLR. It can realize centralized equipment maintenance, and distributed service processing andsubscriber data management.

The virtual HLR function allows authority-based and domain-based management and helpscarriers to provide differentiated services. It facilitates carriers to carry out network planningand equipment maintenance.

The virtual HLR function can greatly reduce the number of NEs used in the network, slash theequipment investment, and cut down the investment and expenses arising from system upgradeand maintenance.

1.4.6 Large Capacity and High IntegrityThe HLR9820 provides large capacity and high integrity. It helps carriers to implementcentralized management and to cut down the OPEX.

The large capacity and high integrity feature of the HLR9820 provides the following benefits:

l Slashing the equipment maintenance cost and the maintenance manpower cost

Six cabinets in full configuration can support 20 million subscribers. The large capacityfeature and centralized management minimize the OPEX.

l Simplifying operations

Carriers can access all the HLRs (HLRs in an area or a country) through a BOSS. Throughthe BOSS, carriers can provide services, such as issuing cards, defining subscribers,providing services, and query services, for subscribers in an area or a country.

l Saving network resources

The nearest HLR FE is accessed for call processing. Thus, the transmission over thesignaling network is simplified, and the network resources are saved.

1.4.7 Separated Data Processing and Service Processing

The HLR9820 adopts separate deployment of the data part and the service part. Compared withthe integrated deployment, the separate deployment enjoys the following advantages:

l More flexible networking

The BE and FE can be deployed in different places. Thus, carriers can determine the numberand location of BEs and FEs based on the population distribution and geographicalconditions.

l Enhanced system compatibility


Product Description


Issue 01 (2008-07-10)

The BEs of the HLR9820 provide standard and open data access interfaces, through whichthe third-party equipment can access the HLR9820. Thus, carriers will not have to botherwith the problem of connecting systems of different suppliers.

1.4.8 Physical Self-Redundancy SolutionsImmeasurable loss will be caused if services are interrupted or important data in the HLR is lostbecause of maloperations, equipment failures, or natural disasters.

To improve the network security and reliability, Huawei provides the remote HLR redundancysolution, that is, an HLR is added to the network to work as the redundancy of the existing HLR.In normal conditions, the active HLR processes various signaling messages and services. Whenthe active HLR fails, the redundancy HLR takes over the service processing, thus ensuringuninterrupted service provisioning over the PLMN. Huawe provides the following HLRredundancy solutions:

l 1+1 mated redundancy solutionThe 1+1 mated redundancy solution allows two sets of Huawei HLRs to work in active/standby mode. In the 1+1 mated redundancy solution, either HLR stores the same subscriberdata as an independent HLR. When the active HLR fails, the redundancy HLR takes overall services from the active HLR.

l N+1 mated redundancy solutionThe N+1 mated redundancy solution allows the networking of N active HLRs and oneredundancy HLR. All the HLRs are provided by Huawei. Here, N ranges from 1 to 254.Generally, a maximum of 10 active HLRs are recommended. The redundancy HLR backsup the data of the active HLRs on a real-time basis. If one or more active HLRs fail, theredundancy HLR takes over services from the faulty active HLRs.

l N+1 compatibility redundancy solutionThe N+1 compatibility redundancy solution allows the networking of N active HLRs andone redundancy HLR. The active HLRs can be provided by different vendors, and theredundancy HLR is provided by Huawei. Here, N ranges from 1 to 254. Generally, amaximum of 10 active HLRs are recommended. The redundancy HLR backs up the dataof the active HLRs on a realtime basis. If one or more active HLRs fail, the redundancyHLR takes over services from the faulty active HLRs.

1.4.9 Smooth Data ConvergenceThe HLR9820 supports smooth evolution towards the USC. It has the capability to convergevarious types of service data, such as the service data of the HSS subscribers and that of theAAA subscribers. It can greatly simplify the data convergence process of traditional HLRs,laying the foundation for service convergence.

1.4.10 Standard and Open Data Access InterfaceIn traditional deployment of new services, carriers have to focus on:

l Service logics

l Complicated subscriber data management, including:– Data structure design

– Data storage

– Data backup



1-13

– Data redundancy

– Data security mechanism

– Data operations

The diversity of equipment provided by different vendors and different data managementmechanisms slow down the development of new services. Failing to promptly deploying newservices hinders carriers from forestalling the competition predominance.

In addition to the capability of integrating the subscriber data of different services, theHLR9820 provides a standard and open data access interface, through which the third-partyapplications can obtain the subscriber data. This feature greatly slashes the service deploymentcost, simplifies the data complexity caused by the emergence of new services, and helps carriersto provide new services.

1.4.11 Comprehensive Data Statistics and AnalysisThe HLR9820 backs up the subscriber data to an independent server at the specified time.Through the independent server, users can query and learn the subscriber data in detail.

This offline data processing mode helps carriers to learn:

l Subscriber data of specific services

l Overall subscriber information, including:– Service subscription and development trend

– Roaming ratio

– Network service features

Based on the information, carriers can learn the network operation, better understand subscribers'behavior, and adjust market strategies in time. Thus, the HLR9820 can help carriers to providetailored services and gain competition predominance.

2.2.3 Data Service LayerThe data service layer provides data services that are independent of service applications. Itsupports distributed data storage, data caching in memory, and remote redundancy of the dataunit.

l DRU

l DSU

DRU

The data routing unit (DRU) queries the subscriber data and provides the data routing function.

The HLR9820 uses multiple DSU clusters to store subscriber data. A routing module is requiredto locate the DSU cluster, which stores the data queried, based on the subscriber identity, andthen to choose a DSU based on the load-balancing strategy to provide data services.

The DRU stores the mapping between the main IMSI of a subscriber and the DSU cluster ID.In addition, the DRU stores the mapping between the MSISDN of a subscriber and the IMSI. Ifthe HLR9820 provides the dual-IMSI service, the DRU also stores the mapping between themain IMSI and the auxiliary IMSI.

Therefore, during the data routing process, the DRU queries the routing table based on the IMSIof the subscriber and finds the DSU cluster where the subscriber data is stored. Then, based onthe load-balancing strategy, the DRU chooses a DSU to provide data services.

DSU

The HLR9820 uses multiple data service unit (DSU) clusters to store subscriber data. The DSUprovides, adds, deletes, or updates data upon the request of the DRU.

The DSU clusters store subscriber data based on the capacity-balancing strategy. All the DSUsin a DSU cluster store the same subscriber data and work in load-sharing mode.

2.2.4 Data Storage LayerThe data storage layer adopts the highly reliable commercialized database management system.It also uses the disk array to provide permanent storage of subscriber data. The hard disks of thedisk array adopt RAID 5+1 technology and hot spare disks to ensure the security of subscriberdata.

4.8.1 NAEAThe North American Equal Access (NAEA) service allows subscribers to choose the toll carrierwhen they originate a toll call. Each toll carrier is assigned with a carrier identity code (CIC).When originating a toll call, the NAEA subscriber can dial the CIC to choose the desired tollcarrier or use the preferred toll carrier that is predefined in subscription.

When subscribing to the NAEA service, the subscriber can choose the preferred toll carrier.Thus, when the subscriber originates a toll call, the call is connected through the network of thepredefined carrier (in this case, the subscriber need not dial the CIC to choose the toll carrier).The subscriber, however, can also dial the CIC to choose the desired toll carrier. If the subscriberneither chooses the preferred toll carrier in service subscription nor dials the CIC when makinga toll call, the call is connected through the default network set by the carrier.

The NAEA service does not apply to:

l International roaming subscribers

l IN subscribers

l Call forwarding (CF) service subscribers

In addition, the NAEA subscriber cannot choose the toll carrier when serving as the called party.

4.8.2 CRBTThe Customized Ring Back Tone (CRBT) service allows subscribers to customize the ring backtone. When the CRBT subscriber is called, the calling party hears the ring back tone customizedby the called party.

The ring back tone can be a piece of music, an advertisement, or a recorded voice.

4.8.3 NCCThe Network Capability Configuration (NCC) feature allows carriers to set on the HLR:

l The capability set of services

l The MAP operations supported by the VLR and the SGSN

The HLR9820 processes services and MAP procedures based on the capability set. This featurecan enhance the network compatibility.

4.8.4 VVDNThe Voice&Videophone Dual Number (VVDN) service allows a subscriber to set differentMSISDNs for the voice service and videophone service. When the subscriber makes calls, theMSISDNs presented to the called party vary according to the call type. If the subscriber makesa voice call, the MSISDN defined for the voice service is presented to the called party. If thesubscriber makes a videophone call, the MSISDN defined for the videophone service ispresented to the called party.

The VVDN service can be provided only when the following conditions are met:

l The MSC/VLR supports the VVDN service.

l The MS supports the bearer service BS20 or BS30.

If a subscriber subscribes to the VVDN service and the alternative line service (ALS), thesubscriber has three MSISDNs:

l Basic MSISDN (MSISDN 1)

l Line 2 MSISDN for ALS (MSISDN 2)

l MSISDN for VVDN

The HLR9820 uses different indicators to identify MSISDN 2 and MSISDN 3. The two numbersdo not conflict with each other.

4.8.5 ARDThe Access Restriction Data (ARD) service allows carriers to restrict the use of the UMTSnetwork by GSM subscribers.

The HLR9820 is added with the access restriction flag. The access restriction flag is transmittedthrough the MAP inserted subscriber data (ISD) between the HLR and the VLR, and betweenthe HLR and the SGSN.

After receiving the ISD, the VLR or SGSN judges whether to allow the subscriber access basedon the access restriction flag carried in the ISD and the wireless access system that serves thesubscriber. If the subscriber access is denied, the VLR or the SGSN returns a message carryingthe cause value. The cause value can be flexibly configured by carriers.

4.8.6 CARP/ARPThe CS Allocation/Retention Priority (CARP) or Allocation/Retention Priority (ARP) serviceallows carriers to set the priority of subscribers in the case of network congestion.

The priorities that can be set through the CARP/ARP service comprise:

l High priority (for subscribers of level 1)

l Common priority (for subscribers of level 2)

l Low priority (for subscribers of level 3)

Carriers can set the subscriber priority for the access process or service hold process.

The HLR9820 manages the CARP/ARP data of subscribers. The HLR9820 sends the CARP/ARP data to the VLR or the SGSN in which the subscriber resides. Upon call setup, the VLRor the SGSN sends the CARP/ARP data to the RNC. The RNC provides differentiated servicesto subscribers based on the CARP/ARP priorities.

The CARP service is applicable to CS subscribers only, and the ARP service is applicable to PSsubscribers only.

4.8.7 VBSThe Voice Broadcast Service (VBS) allows a broadcast call to be set up for a group of subscribersin a service area.

This service is implemented in simplex mode. Only the calling party communicates in duplexmode. During the call, only the calling party can speak, and others can only listen.

In a VBS call, a broadcast channel is set up for each cell in the broadcast area. All the subscribersin a cell receive the voice by sharing the broadcast downlink channel.

The VBS call can also be connected to dispatchers. Each group call supports the connections toa maximum of five dispatchers.

A VBS call can be originated by a service subscriber or an authorized dispatcher.

The members who can join a VBS call comprise dispatchers and service subscribers.

l Dispatcher

A VBS call allows a maximum of five dispatchers. The dispatchers can be PSTNsubscribers or PLMN subscribers. They join the group calls through the dedicated channel.

l Service subscriber

Service subscribers are PLMN subscribers who can use the VBS. They join the group callthrough the group call channels in the group call area.

A VBS subscriber can set up a call to a group of subscribers in a specified area or to a group ofsubscribers sharing the same group ID.

A group call area can cover the cells served by the same MSC or served by different MSCs.Each cell in a group call has a group call channel. The uplink can be used by the speaker only.The downlink is used by all listeners. The notification messages related to the group call arebroadcast through the notification channel (NCH).

4.8.8 VGCSThe Voice Group Call Service (VGCS) allows a broadcast call to be set up to a subscriber groupin a service area. The call is implemented in half duplex mode. During the call, any servicesubscriber can get the floor to speak. When a person speaks, however, the others can only listen.

During the setup of a VGCS call, dedicated connections to dispatchers are also set up. Thedispatchers communicate in full duplex mode. That is, the dispatchers can receive the group callinformation and broadcast information to the whole group.

A VGCS call can be originated by a service subscriber or an authorized dispatcher.

The members who can join a VGCS call comprise dispatchers and service subscribers.

l DispatcherA VGCS call allows a maximum of five dispatchers. The dispatchers can be PSTNsubscribers or PLMN subscribers. They join the group calls through the dedicated channel.

l Service subscriberThe service subscribers are PLMN subscribers who can use the VGCS. They join the groupcall through the group call channels in the group call area.

During a VBS call, only the call originator can speak. During a VGCS call, however, in additionto the dispatchers, the service subscribers can speak by preempting the uplink channel.Therefore, compared with the VBS, the VGCS requires the management or control of uplinkchannels.

4.8.9 FMThe FollowMe (FM) service is also known as the functional number addressing service. It allowsa subscriber to modify the FM data of the functional number registered. Thus, all the callsaddressed to the functional number are forwarded to the subscriber.

The FM service is similar to the CFU service. Different from the CFU service, the FM serviceallows the FM subscriber (forwarded-to party) to manage the FM service data of the called party.The functional number is a virtual number. In special cases, it can be a number of a GSMsubscriber.

In trunk communication, the functional number is an employment position number rather thana subscriber number. Through the FM service, the person on duty has the calls addressed to thefunctional number forwarded to his or her own MSISDNs, thus creating the association betweenthe functional number and the subscriber. When the dispatcher calls the functional number, thecall is forwarded to the person on duty. The MSISDN changes along with the person on duty,but the functional number remains the same.

The HLR9820 provides the ability to store, modify, and query the FM service data. It allowscarriers to set the FM service through the SMU and allows subscribers to set the FM servicethrough their MSs. It supports the setting of the MSISDNs mapping the functional number.

To ensure security, the HLR9820 provides the authority check on FM subscribers. The authoritycheck comprises the check on the class of registration (COR) and that on the authority range.

4.8.10 UUSThe User-to-User Signaling (UUS) service allows a subscriber to send and receive the user-to-user information (UUI) during a call. The UUI is created by subscribers and transferredtransparently through the network. Generally, the PLMN does not explain the UUI.


Product Description


Issue 01 (2008-07-10)

Based on the stage where the UUI is triggered, the UUS service can be classified into thefollowing types:

l UUS1

The UUI is sent and received in mobile-originated calls and MTCs.

l UUS2

The UUI is sent when the called party is alerted.

l UUS3

The UUI is sent and received after the call is set up.

NOTE

MAP 1 and MAP 2 support UUS1, and MAP 3 supports UUS1, UUS2, and UUS3.

A subscriber can apply for the UUS service through:

l Implicit request

The MS sends the UUI in a SETUP message. The implicit request does not require aresponse from the peer end. The UUS service is activated as soon as the service check issuccessful.

l Explicit request

The MS sends requests and responses through the FACILITY cell in the call controlsignaling. The coding of FACILITY complies with the GSM0480 protocol. The explicitrequest for UUS1 can also carry the UUI.

The UUS explicit request can be classified into the following two types:

– Mandatory request: If the UUS service cannot be activated, the call is cleared.

– Optional request: If the UUS service cannot be activated, the call proceeding continues.

The HLR9820 supports the UUS service. It stores the USS data, allows the USS data to bemodified or queried, and updates the UUS data in the VLR.

4.8.11 eMLPPThe enhanced Multi-Level Precedence and Pre-emption (eMLPP) service is a supplementaryservice defined by the 3GPP.

This service allows a subscriber with a higher priority to enjoy a faster call setup. When the callresources are insufficient, the call with a higher priority can use the resources (A-interfacecircuits and trunk circuits) first. Thus, the call with a higher priority can be connected. Thisservice helps carriers to provide differentiated services to subscribers.

The eMLPP service provides seven priorities: A, B, 0, 1, 2, 3, and 4. Of the seven priorities, Aand B are reserved for internal use. A subscriber can be assigned with a highest priority and adefault priority. The default priority cannot override the highest priority.

If the MS supports the modification of the call priority, the subscriber can modify the defaultpriority through the MS. During the location update procedure, the HLR9820 sends the highestpriority and default priority to the VLR.

The HLR9820 supports the eMLPP service. It stores the eMLPP data, allows the eMLPP datato be modified or queried, and updates the eMLPP data in the VLR.



4-11

4.8.12 ADDThe Automatic Device Detection (ADD) function allows the HLR to send the related informationto the ADD server (a third-party service platform) when the HLR detects the change of any ofthe following information of a subscriber:

l International Mobile Equipment Identity (IMEI) or International Mobile EquipmentIdentity Software Version (IMEISV)

l IMSI

l MSISDN

l Subscriber type (pre-paid service subscriber or post-paid service subscriber)

The ADD server updates the information stored in the user equipment (UE) through a shortmessage or a USSD message based on the service requirements specified by the carrier.

The ADD function simplifies the operations of the end users who use data services, and thusincreases the customer satisfaction. For example, the data setting of the GPRS services iscomplicated. If a user uses a new UE, the ADD server obtains the information of the new UEand sends a short message or USSD message to the UE to update the related information.

Product Description


Issue 01 (2008-07-10)

l When the total volume of the provided services is close to the value of the License, theHLR9820 generates an alarm.

l When the number of subscribers reaches the value of the License, no more subscribers canbe added.

4.9.3 System-Wide Clock SynchronizationThe HLR9820 uses Network Time Protocol (NTP) to realize clock synchronization. To maintaintime synchronization, the BAM adjusts its clock according to the clock source provided by theM2000, and the other modules in the system adjust their clocks according to the clock of theBAM.

4.9.4 IP TOS ConfigurationTo improve transaction capabilities of the network and adapt to the convergence oftelecommunication network and IP network, the HLR9820 supports the configuration of the IPType of Service (IP TOS).

The IP TOS technology is used in routers. A router determines the priority of IP packets basedon the value of the IP TOS. The IP packet with a higher priority takes precedence over the onewith a lower priority in the case of network congestion.

To meet different network requirements, the HLR9820 supports the global configuration andlocal configuration of the IP TOS.

The IP POS is managed by carriers globally. The priority of IP packets are determined based onactual network conditions.

4.9.5 LMSIThe HLR9820 saves the current location area code (LAC) of subscribers in the Local MobileStation Identity (LMSI) cell.

The HLR9820 transmits the LAC in the LMSI cell. During the location update procedure, theVLR sends the LAC in the LMSI cell to the HLR. The HLR stores LMSI without making anychange. Then, the HLR sends LMSI to the VLR in a providing roaming number (PRN) request.

4.9.6 DST ChangeIf the time of the HLR9820 is different from that of the NMS, data loss or data duplication mayoccur. To ensure time consistency between the NEs and the NMS in the network, theHLR9820 provides the daylight saving time (DST) management function.

The HLR9820 allows carriers to set the time zone and automatic change of the DST based onthe local DST rules in site implementation.

The HLR9820 provides the following functions:

l Allowing users to query the time zone and DST on the BAM client

l Presenting the DST flag in the GUI time displayed on the performance measurement system
