Problems solved by technology

[0018] The technical problem to be solved by the present invention is to overcome the disadvantages of the existing technology that when the identifier groups at the two ends of the connection and message sending and receiving are not in one-to-one correspondence, the connection cannot be directly used for transaction reliability processing, and to provide a connection and message A method for conveniently and reliably implementing H.248 message transmission and transaction reliability processing when the identifier groups at the sending and receiving ends have different correspondences

Embodiment Construction

[0042] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0043]H.248 protocol messages are transmitted on TCP connections. In order to ensure the reliable transmission of transactions in H.248 messages, transaction reliability processing needs to be implemented. If transaction reliability processing is directly implemented for connections, in some cases in actual situations Difficult to deal with.

[0044] The present invention introduces association (association) at the H.248 protocol layer, and makes MID not directly correspond to connection (connection), but makes MID and connection respectively establish correspondence with association, like this, makes MID and connection indirectly establish correspondence through association Relationship, a local MID and a peer MID uniquely correspond to an association, so transaction reliability can be realized on an association. The association can be regarded as a logi...

Abstract

The invention relates to the field of telecommunication, which realizes the method for message transmission of media gateway control protocol (H.248) and business reliability processing, wherein association is introduced into the H.248 protocol layer, a local end message transmitter marking identification character (MID) and an opposite end message transmitter marking identification character (MID) are corresponding to one association, the application layer of the H.248 protocol builds the corresponding relation between the association and the connection based on the real situation for business reliability processing on the association, and performs message reception and transmission according to the corresponding relation between the association and the connection.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing media gateway control protocol (H.248) message transmission and transaction reliability processing. Background technique [0002] The Media Gateway Control Protocol (H.248) is a protocol applied between the Media Gateway Controller and the Media Gateway. The Media Gateway Controller is responsible for controlling the call status related to the Media Gateway. Complete the conversion of media formats between different networks under control. As shown in Figure 1, it is a schematic diagram of the position of the H.248 protocol in the TCP / IP protocol layered model. The messages of the H.248 protocol are mainly transmitted on the IP. (TCP, Transmission Control Protocol) or User Datagram Protocol (UDP, User Datagram Protocol), etc. UDP provides a connectionless message service, while TCP provides a connection-oriented streaming service. The so-called conne...
