SIP (SessionInitiationProtocol) is the signaling control protocol of an application layer.For creating, revising and discharge the session of one or more participant.

MGCP (MediaGatewayControlProtocol) MGCP.Agreement comprises media gateway controller MGC (MediaGatewayController) and multimedia gateway unit MG (MediaGateway) two kinds of objects.The attended operation that MGC passes through establishment, amendment and deletes between MG, MG realizes the media session process of foundation and control and other MG.

H.248: MGCP, it is that MGCP protocol basis in early days improves.H.248 agreement is by the agreement of MGC control MG, also claims MeGaCo.H.248 introduce context(environment in) concept, add many package(and wrap) definition, thus MGCP is pushed away greatly further.

Summary of the invention

The technical problem to be solved in the present invention, is that providing a kind of realizes the three-in-one fusion method of agreement based on integrated access equipment IAD, achieves the compatibility to SIP, MGCP, H.248 three kind of session control protocol, has saved the memory space of equipment I AD.

The present invention is achieved in that and a kind ofly realizes the three-in-one fusion method of agreement based on integrated access equipment IAD, specifically comprises the steps:

Step 1, on equipment I AD set three kinds of protocol environments, and under described three kinds of protocol environments respectively corresponding definition have an executable program, described executable program is respectively Session Initiation Protocol executable program for performing Session Initiation Protocol, for performing the MGCP agreement executable program of MGCP agreement and the H.248 agreement executable program for performing H.248 agreement; Described Session Initiation Protocol executable program comprises Session Initiation Protocol module, call management module and digital signal processing module, described MGCP agreement executable program comprises MGCP protocol module, call management module and digital signal processing module, and described H.248 agreement executable program comprises H.248 protocol module, call management module and digital signal processing module; Described call management module: the foundation of all calls on control and management equipment I AD, amendment, dispose procedure; Described digital signal processing module: for the conversion of analog signal, digital signal, rectification, filtration, separation, generation, testing;

The parameter of the starting factor file BOOT in step 2, amendment equipment I AD carrys out the flexible switching to three executable programs;

Step 3, after equipment I AD sets starting factor file BOOT, when IAD device start, according to the amendment to described starting factor file BOOT, quote the executable program under corresponding protocol environment, thus the conversation control function after startup is provided.

Tool of the present invention has the following advantages: present invention achieves the compatibility of equipment I AD software to SIP, MGCP, H.248 three kind of session control protocol; And achieve the flexible switching of equipment I AD software in three kinds of session control protocol environment; Provide the basis of software of compatible more session control protocols fast; Save the memory space of equipment I AD.

Embodiment

Refer to shown in Fig. 1 to Fig. 3, the present invention a kind ofly realizes the three-in-one fusion method of agreement based on integrated access equipment IAD, specifically comprises the steps:

As shown in Figure 2, the software module structure of such integrated access equipment IAD just has module level and module interface, thus by independent for original each protocol module.The Depending modules such as three kinds of public Call-Control1 call management module of executable program, digital signal processing modules, thoroughly make a distinction protocol module and functions of the equipments module while reducing code redundancy.Here each protocol module is realized independent, thus ignore agreement, equipment is made to run the committed step not relying on protocol module, be to define the call state machine of a set of public, indiscriminate, independent protocol, irrelevant platform, functions of the equipments are run by state machine and are realized, and the various trigger events of state machine, then decided how to send according to respective signaling process by executable program;

The parameter of the starting factor file BOOT in step 2, amendment equipment I AD carrys out the flexible switching to three executable programs; Described step 2 is specially:

Step 20, design Command Line Interface CLI or a Web page, realize the parameter flag that operating personnel are imported into, carry out by this parameter flag the protocol environment being switched to needs;

Step 21, preparation memory space obtain the starting factor file BOOT of current use;

Step 22, by parameter flag the startup file name in starting factor file BOOT parameter to be revised as the protocol environment that will be switched under corresponding executable program title (i.e. three executable program titles: Session Initiation Protocol executable program, MGCP agreement executable program and H.248 agreement executable program);

Step 23, again starting factor file BOOT after amendment is re-write in hardware memory space;

Step 24, restarting equipment IAD, equipment I AD system use new starting factor file BOOT to perform corresponding executable program, and protocol environment can complete flexible switching;

Like this three executable programs are done different name (i.e. three executable program titles: Session Initiation Protocol executable program, MGCP agreement executable program and H.248 agreement executable program), leave in the memory space of device memory, find different executable programs when BOOT file start according to different start-up parameter marks and support to three kinds of session control protocols can be provided at any time easily; The switching of protocol environment also just can simply by restarting software to realize;

Step 3, after equipment I AD sets starting factor file BOOT, when IAD device start, according to the amendment to described starting factor file BOOT, quote the executable program under corresponding protocol environment, thus the conversation control function after startup is provided;

Set up call after the call management module reception conversation session event of step 4, executable program, analog signal in the call of foundation is converted to the response that digital signal completed this session control request afterwards by described digital signal processing module.

Wherein, described session control request comprises the deletion of the establishment of call, the amendment of call or call; The deletion of the establishment of described call, the amendment of call or call all operates by sending event notice call management module.

Under described three kinds of protocol environments, corresponding definition has an executable program to be specially respectively: write at code, compile in distinguish each protocol code by different agreement macrodefinitions, guarantee that code is write or is compiled in a moment and all only pays close attention to a kind of protocol environment; When defining different agreements and being grand, compiled code will obtain the executable program supporting corresponding protocol environment, defines three kinds of agreements respectively grand, and point three compilings obtain an executable program of corresponding three kinds of protocol environments respectively.

In a word, of the present inventionly a kind ofly realize the three-in-one fusion method of agreement based on integrated access equipment IAD, achieve the compatibility to SIP, MGCP, H.248 three kind of session control protocol, saved the memory space of equipment I AD.

The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
