QOS Trial airtel Nigeria


› Static QoS to be implemented for the E2E QoS.› Changing of the Traffic Handling Priority of the MSISDN to be used for POC in the HLR.› Throughput difference also need to be captured by congestion simulation in radio side.

› No Congestion simulation to be done in any other node except RAN

SCOPE


Network architecture

Qos Setting implemented :

- Nodeb’s LG0999 , RNC - ELGRN08 , DXX 8660 , HLR , SGSN


HLR Profiling

SGSN Parameter :-• Traffic handling priority parameter change from 3 to 1


The below QoS Features are already implemented and configured in the RNC’s:

– EulMbrQosProfiling FAJ1211091 HSDPA MBR for QoS profiling

– FlexArpMap FAJ1211093 Flexible QoS and Allocation/Retention Handling

– HsMbrQosProfiling FAJ1211091 HSDPA MBR for QoS profiling

– QosMapDL FAJ1211093 Flexible QoS and Allocation/Retention Handling

– QosMapUL FAJ111093 Flexible QoS and Allocation/Retention Handling

– ThpSupportHspa FAJ1211094 Traffic Handling Priority

– TnlQosMap FAJ121966 Configurable transport bearerQoS class

The below Features are activated and configured:

– ArpToSpiMappingDL FAJ1211382 HSPA QoS scheduling priority based on ARP

– ArpToSpiMappingUL FAJ1211382 HSPA QoS scheduling priority based on ARP
