Communication protocols in networks having split control planes and user planes

摘要

Concepts are mapped between Media Gateway Control protocols (e.g., H.248/MEGACO) and specifications for packet-switched services like the General Packet Radio Service (GPRS), enabling Media Gateway Control protocols to be applied in a GPRS environment. For example, a GPRS user-plane entity can represent part or all of a (GPRS) mobility management context by a (Media Gateway Control protocol) Context. Also, a GPRS user-plane entity can represent at least the part of a (GPRS) PDP context going towards a user-plane peer as a (Media Gateway Control protocol) Termination. Two GPRS Tunneling Protocol (GTP) tunnels related to one PDP context (either a primary PDP context or a secondary PDP context) and going towards the same user plane peer can be represented by a (Media Gateway Control protocol) Stream, and a (GPRS) GTP tunnel containing received packets can be represented by a (Media Gateway Control protocol) Local Descriptor. In addition, a (GPRS) GTP tunnel containing sent packets can be represented by a (Media Gateway Control protocol) Remote Descriptor.
