Description
Technical field
The present invention relates to field of communication technology, in particular to the method for releasing and system of a kind of temporary destination node.
Background technique
H.248 agreement is Media Gateway Controller (MGC)/soft switch (SS, Soft Switch) in NGN flexible exchanging network
One of with Media Gateway (MG) interface protocol；MGC/SS is communicated by H.248 agreement with MG, completes to connect in MG with media channel
Connect the control for controlling relevant call state.H.248 the link model of protocol definition includes that destination node and context two are main
Concept, wherein be packaged with the parameters such as media stream parameters, modem and bearing capacity in destination node, be Media Gateway logic
Entity can send or receive one or more Media Stream；Context is the connection between one group of destination node.Destination node can divide
For physics destination node and temporary destination node, wherein physics destination node can represent physical entity, for example, a time division multiplexing
(TDM) channel can be used as a physics destination node；Temporary destination node can represent provisional information flow, be used for for example, representing
Carry real time transport protocol (RTP, the Real-time Transport of voice, data and vision signal or various mixed signals
Protocol it) flows.By the protocol message communication of H.248 protocol definition between MGC/SS and MG, complete destination node addition or
Release.In practical applications, H.248 the protocol message of protocol definition be transmitted on User Datagram Protocol (UDP), but
The unreliability of UDP transmission, the protocol message for being likely to result in H.248 protocol definition cannot reach destination or loss in time,
Wherein, it if what is lost is release temporary destination node order, will lead to interim corresponding to the release temporary destination node order
Destination node cannot discharge；If cannot reach destination or loss in time is the response message for creating temporary destination node order,
MGC/SS retransmits creation temporary destination node order, if receive the creation temporary destination node order of MGC/SS re-transmission, MG is first
The secondary affairs for receiving the creation temporary destination node created after creation temporary destination node order have timed, out and delete, then can hold again
The creation temporary destination node order that row retransmits creates temporary destination node, in this way, MG is just added to two temporary destination nodes, but MGC/
SS then thinks that MG is only successfully added to a temporary destination node, and under the temporary destination node for the addition that only can think to have succeeded for it
Hair release temporary destination node order, causes another temporary destination node that cannot discharge.
Summary of the invention
The present invention provides the method for releasing and system of a kind of temporary destination node, for realizing the release to temporary destination node.
To achieve the above object, the present invention provides a kind of method for releasing of temporary destination node, comprising:

Body gateway controller；
The Media Gateway, for sending off-hook information to the Media Gateway Controller, the off-hook information includes institute
State all contextual informations of Media Gateway；Discharge the interim end of the not stored contextual information of the Media Gateway Controller
Node.
The Media Gateway Controller, for compare storage the Media Gateway all contextual informations with it is described
Whether all contextual informations of the Media Gateway in off-hook information are consistent；If comparing the media net of storage
All contextual informations of the Media Gateway in all contextual informations closed and the off-hook information are uneven consistent
When, context exception information is returned to the Media Gateway, the context exception information includes the Media Gateway Controller
The contextual information of the not stored Media Gateway.
Optionally, if the Media Gateway Controller be also used to compare the Media Gateway of storage it is all up and down
Literary information is consistent with all contextual informations of the Media Gateway in the off-hook information, returns to the Media Gateway
Return context normal information.
Optionally, all contextual informations of the Media Gateway in the off-hook information are increased by Extended Protocol
Add.
The invention has the following advantages:
