Problems solved by technology

[0008] The technical problem to be solved by the present invention is: to overcome the development difficulties and the inadequacies that the two media gateway control protocols of MeGaCo / H.248 and MGCP in the existing MGC or MG adopt their own independent application adaptation systems and are not easy to expand, Provides an implementation method of media gateway control protocol application adaptation and compatibility, so as to facilitate product upgrade and expansion

Embodiment Construction

[0029] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0030] Such as figure 2 Shown is a schematic diagram of the application adaptation compatibility system of the media gateway control protocol of the present invention. The compatibility system of the present invention consists of a transport layer (Transport Layer), a transport adapter (TransportAdapater), a protocol stack (Protocol Stack), a protocol adapter (Protocol Adapter), Media Gateway Control Application Program Interface (Media Gateway Control Application Program Interface), Service Process (Service Process), and Media Resource (Media Resource) are composed of several parts.

[0031]MeGaCo / H.248 and MGCP two media gateway control protocols have their own independent protocol stack (PS) and protocol adaptation (PA). The protocol stack mainly completes the encoding and decoding function of the protocol. The MeGaCo / H.248 protocol can choose two enc...

Abstract

A method for implementing compatible media gateway control protocol application adaptation, using a unified media gateway between the independent protocol adaptation layer and the shared service processing layer of two media gateway control protocols (MeGaCo / H.248, MGCP) The control application program interface (MGCAPI) communicates. MGCAPI uses transactions as the basic unit of interface interaction information, and adopts hierarchical nested data structures of transactions, actions, commands, and descriptors; MCAPI interface messages communicate with their respective media at the protocol adaptation layer The gateway controls the conversion of protocol messages, converts MCAPI messages into protocol data units that can be processed by their respective protocol stacks, and converts protocol data units decoded by their respective protocol stacks into MCAPI messages. The invention can speed up the development process of MGC and MG, facilitate the upgrade and expansion of products, and reduce the maintenance cost of MGC and MG.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for implementing adaptation and compatibility of media gateway control protocol applications. Background technique [0002] MGC (Media Gateway Controller) and MG (Media Gateway) are two key components in NGN (Next Generation Network). The MGC is responsible for the call control function, and the MG is responsible for the service bearer function, thereby realizing the separation of the call control plane and the service bearer plane, thereby fully sharing network resources, simplifying equipment upgrades and service expansion, and greatly reducing development and maintenance costs. [0003] The media gateway control protocol is the main protocol for communication between the MGC and the MG. Currently, MeGaCo / H.248 and MGCP are widely used. Among them, the MGCP protocol (V1.0) was formulated by the IETF (Internet Engineering Task Force) in October 1999, and ...
