Embodiment Construction

[0059] The present invention will be described in further detail according to embodiment below:

[0060] The present invention is based on the H.248 agreement to the regulation on IP transmission, has adopted state machine to realize the reliable transmission of transaction (Transaction), is described in detail as follows:

[0061] Save the request transaction (Transaction Request) sent by the protocol entity to the peer entity in a request (Request) queue, and save the response transaction (Transaction Reply) in response to the request transaction (Transaction Request) received from the peer entity in A response (Response) queue, the transaction (Transaction) in the two queues respectively completes the corresponding operation and state change according to the event that triggers the state change, and uses the state machine mechanism to realize the reliable transmission of the transaction (Transaction).

[0062] The status of the Transaction in the Request queue is shown in T...

Abstract

Transaction Request sent by protocol entity to opposite entity is kept in Request queue, and Transaction Reply received from opposite entity for responding Transaction Request is kept in Response queue. Based on event trigging change of state, Transactions in two queues complete corresponding operation and change of state. Thus, reliable transmission of Transactions is realized by using mechanism of state machine. The invention overcomes disadvantages of realizing reliable transmission of Transactions: complicated mechanism and difficult to control testing.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing reliable transmission of transactions on an IP network. Background technique [0002] In the next generation network and softswitch networking architecture, the media gateway controller (MGC) controls the media gateway (MG) through the media gateway control protocol (H.248). The H.248 protocol is a master-slave protocol, with the media gateway controller as the master and the media gateway as the slave. The media gateway controller is responsible for controlling the call status related to the media gateway, and the media gateway is under the control of the media gateway controller. To complete the conversion of media formats between different networks, if the message sent by the media gateway controller cannot be responded in time, it may lead to repeated sending, which will lead to unpredictable status of the media gateway after executing the command...
