2 Technical DescriptionActive Queue Management (AQM) can actively optimize the management of RLC queues toreduce the delay of HTTP service data in buffer queues.Currently, most communication systems use Transmission Control Protocol (TCP) to guaranteethe reliability of data services. When TCP is applied to the WCDMA network, one radio bearer(RB) can simultaneously use multiple TCP connections (multi-thread) and a great number ofdata packets may wait in the buffer queue, which leads to a high queuing delay. As a result, thefollowing problems may occur:l When a queue is long, the round trip time (RTT) of the synchronization packet of a new

connection is also long, whereas the initial value of the retransmission timeout (RTO) timeris relatively small. Therefore, the RTT may be longer than the RTO time, that is, the RTOtimer may expire before the new connection is established.

l When a high-priority traffic stream occupies most of the buffer, it is difficult for otherstreams to occupy the required bandwidth. As a result, the subsequent data packets of theother streams are likely to be discarded due to buffer overflow.

l When consecutive loss of packets occurs due to buffer overflow, the TCP link takes a longtime to retrieve the earlier data rate. In such a case, the link cannot be fully used.AQM optimizes the management of RLC queues, reduces the situations that the HTTPservice data are blocked by other services. It can improve the user experience in HTTPservice.

AQM identifies an HTTP service by the TCP port number carried in the service packet. Thedefault TCP port number is 80 for HTTP services.The AQM algorithm applies to data transmission in the downlink rather than the uplink.The AQM algorithm does not require support from other NEs.The AQM algorithm must be implemented before the PDCP header compression algorithm isimplemented.

3.2 ActivationRun the RNC MML command SET UCORRMALGOSWITCH (CME single configuration:UMTS Radio Global Configuration Express > Connection_Oriented RRM SwitchConfiguration > Connection Oriented Algorithm Switches; CME batch modification center:Modifying RNC Parameters in Batches) to turn on the RNC-level AQM switch. In this step,select the check box DRA_AQM_SWITCH under the parameter Dynamic resource allocationswitch (DraSwitch(BSC6900,BSC6910)).

3.3 Activation ObservationStep 1 Select the "UI_FAM_UT_INTRA_MSG" in the "Message Setting" dialog box on the RNC

LMT.

Figure 3-1 Message setting dialog box

Step 2 Initiate UE tracing on the RNC LMT. In the displayed UE Trace dialog box, select the DebugMode check box, as shown in Figure 3-2.

Step 3 Establish a BE service on the UE. Verify the value of the information element (IE)"ucAqmSwitch" contained in the message PdcpSetupInfo in the CRLC_SETUP_REQ messageas follows:l If the value of the IE "ucAqmSwitch" is 1, this feature has been activated.l If the value of the IE "ucAqmSwitch" is 0, this feature is not activated.----End

3.4 DeactivationRun the RNC MML command SET UCORRMALGOSWITCH (CME single configuration:UMTS Radio Global Configuration Express > Connection_Oriented RRM SwitchConfiguration > Connection Oriented Algorithm Switches; CME batch modification center:Modifying RNC Parameters in Batches). In this step, deselect the DRA_AQM_SWITCH checkbox under the parameter Dynamic resource allocation switch (DraSwitch(BSC6900,BSC6910)).
