Digital cellular telecommunications system (Phase 2+); Packed-switched handover for GERAN A/Gb mode; Stage 2
|Publication Date:||1 October 2012|
The present document defines the stage-2 service description for packet switched handover in GERAN A/Gb mode and GAN mode. ITU-T Recommendation I.130  describes a three-stage method for characterisation of telecommunication services, and ITU-T Recommendation Q.65  defines stage 2 of the method. The present document refers to packet switched handover in GERAN A/Gb mode/GAN mode, and therefore focuses on the corresponding radio protocol enhancements to the packet switched domain only i.e. when services are provided through the Gb interface.
