Abstract
The present application discloses a method for voice interconnection and interworking between an IMS and a 3G or 4G system. The method includes: deploying an AMR transcoder in an IMS system, wherein the AMR transcoder encodes and decodes by means of software encoding and decoding; and during a process of communication with the 3G or 4G system, a medium server or gateway agent in the IMS system inputting a medium stream to the AMR transcoder for AMR encoding and decoding. Applying the technical solution disclosed in the present application can achieving interconnection and interworking between the IMS and the 3G and 4G systems.
Description
Technical field
The application relates to mobile communication technology field, particularly a kind of method making the Voice over Internet intercommunication of IMS and 3G or 4G system.
Background technology
Along with the development of the communication technology, 3G and 4G obtains applying more and more widely in the communication system of different field, if WCDMA, TD-SCDMA of 3G is in the large-scale application of PLMN public network system, and the large-scale application of LTE in public network and multimedia cluster.Meanwhile, IMS (Internet Multimedia Service) is also at development, and IMS and mobile network are combined into the important directions that current operation merges.
Because the speech business of WCDMA, TD-SCDMA and LTE system uses AMR (AdaptiveMulti-Rate) to encode, instead of the widely used G711/G729/G723 encoding and decoding of IMS, therefore, the transcoding issues that solve AMR could realize 3G/4G system and IMS integrated services.
Summary of the invention
This application provides a kind of method making the Voice over Internet intercommunication of IMS and 3G or 4G system, to realize interconnecting between the speech business of IMS and 3G, 4G system.
A kind of method making the Voice over Internet intercommunication of IMS and 3G or 4G system that the application provides, comprising:
In IMS system, dispose AMR transcoder, described AMR transcoder adopts the mode of software codec to carry out encoding and decoding;
With the process of 3G or 4G system communication, Media Stream is inputted described AMR transcoder and carries out AMR encoding and decoding by the media server in IMS system or gateway proxy.
Preferably, the signaling plane of described IMS system is separated with user face.
Preferably, the signaling between described IMS system and 3G or 4G system adopts the transformational relation of SIP or SDP protocol negotiation AMR and G711 or 729 or 723.
Preferably, 3G or 4G system mails to the code stream carrying use Real-time Transport Protocol of IMS system.
Preferably, described AMR transcoder is the software that can dispose separately, and itself and host software are at same node or different node.
Preferably, the method comprises further: use AMR transcoder being adopted to capability negotiation mechanism control AMR transcoder resource.
Preferably, described capability negotiation mechanism comprises:
AMR transcoder adopts cycle or event mode to report actual computing capability or available resources;
Main frame judges whether to increase or reduce transcoding way according to reporting of AMR transcoder.
Preferably, the method comprises further: according to the transcoding capabilities of bearer resource dynamic-configuration AMR transcoder.
As seen from the above technical solution, the method of the Voice over Internet intercommunication of IMS and 3G or 4G system that what the application provided make, by disposing AMR transcoder in IMS system, and with the process of 3G or 4G system communication, by the media server in IMS system or gateway proxy, Media Stream is inputted described AMR transcoder and carry out AMR encoding and decoding, make to achieve between the speech business of IMS and 3G, 4G system to interconnect.
Accompanying drawing explanation
Fig. 1 is the configuration diagram that the application disposes AMR transcoder.
Embodiment
For making the object of the application, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the application is described in further detail.
In order to solve the problem existing for prior art, the application proposes to adopt the mode of software codec, and AMR transcoding is designed to independent software transcoder, between the user face being deployed in IMS and 3G/4G, carries out AMR encoding and decoding separately.So, neither account for the operational capability of IMS main frame, also extra demand is not proposed to universal gateway, easy to use, and performance efficiency.
Fig. 1 is the configuration diagram that the application disposes AMR transcoder.Be still a part for IMS system according to Fig. 1, AMR transcoder, but be the software that can independently dispose, can at same node with host software, also can at different node.AMR transcoder also can be disposed in multiple host distribution.Media Stream inputs after AMR transcoder carries out AMR encoding and decoding and exports by media server or gateway proxy.
The technical requirement of the application to AMR transcoder comprises:
1) require that the signaling plane of IMS system is separated with user face;
2) signaling between 3G/4G and IMS system adopts SIP/SDP to consult the transformational relation of AMR and G711/729/723.
3) 3G/4G mails to the code stream carrying use Real-time Transport Protocol of IMS.
Consider that AMR encoding and decoding need to occupy larger computational resource, how effectively to control the important technology that resource use is also its even running.For this reason, the application is that AMR transcoder introduces capability reporting and negotiation mechanism, specifically:
1) AMR transcoder adopts cycle or event mode to report actual computing capability or available resources;
2) main frame judges whether to increase or reduce transcoding way according to the ability that AMR transcoder reports;
3) transcoding capabilities of AMR transcoder can dynamic-configuration according to bearer resource.
At present, the existing software codec of industry mainly fixed network transmission the mutual conversion between G711A/U, G723, G729 etc., not used for the software codec that the AMR of WiMAX and the speech-encoded format of arrowband fixed network change.WiMAX voice and current existing voice system can be merged at core net level or service application layer by AMR transcoding by the application easily very well.
The foregoing is only the preferred embodiment of the application, not in order to limit the application, within all spirit in the application and principle, any amendment made, equivalent replacements, improvement etc., all should be included within scope that the application protects.
