Dynamically assignable resource class system to directly map 3GPP subscriber communications to a MPLS-based protocol

摘要

It is desirable to enhance the current General Packet Radio Service to be able to support the additional stringent delay requirements of the additional service classes defined in the ETSI Universal Mobile Telecommunication Service Phase 2+ General Packet Radio Service recommendations to thereby arrive at a single IP-based integrated network capable of providing all classes of service from conversational to best effort data. To be spectrally efficient for all of these service classes, it is necessary to be able to efficiently multiplex several data sessions with different QoS delay requirements on the same set of channels. The Dynamically Assignable Resource Class System accomplishes this by enhancing the existing slow access procedure implemented in the General Packet Radio Service medium to include fast in-session access capability.
