Embodiment
In order further to explain technical scheme of the present invention, the present invention will be described in detail below by specific embodiment.
As shown in Figure 1, what the present invention relates to is a kind of based on SIP and H323 dual stack system, comprises H323/SIP protocol stack 1, the outer adaptation layer 2 of H323 protocol stack, the outer adaptation layer 3 of Session Initiation Protocol stack, VOIP module 4 and message adaptation layer 5.
This H323/SIP protocol stack 1 has separate H323 protocol stack and Session Initiation Protocol stack, this H323 protocol stack is connected with outer adaptation layer 2 communications of H323 protocol stack, this Session Initiation Protocol stack is connected with outer adaptation layer 3 communications of Session Initiation Protocol stack, the outer adaptation layer 2 of this H323 protocol stack all is connected with 4 communications of VOIP module with the outer adaptation layer 3 of Session Initiation Protocol stack, particularly, the outer adaptation layer 2 of this H323 protocol stack and the outer adaptation layer 3 of Session Initiation Protocol stack all are provided with the package interface that service is provided for VOIP; This VOIP module 4 is connected with 8 communication of GUI layer by message adaptation layer 5.
Like this, a kind of system of dual stack based on SIP and H323 that the present invention relates to, it is provided with SIP and H323 agreement on terminal, when making terminal can be under the environment that only has SIP or H323 normal, and under the environment of existing SIP and H323, it can switch by supported protocol again, in SIP service or abnormal situation of H323 service, can not affect user's normal use, specifically by VOIP module 4, carry out Coordination Treatment.
Referring again to shown in Figure 1, should also comprise console layer 6 and telnet port 7 based on SIP and H323 dual stack system, this console layer 6 is connected with 4 communications of VOIP module, this telnet port 7 is connected with 6 communication of console layer, so can be exploitation and tester's indentification protocol stack interface and use, the interface of test use is provided.
As shown in Figure 2, the present invention also provides a kind of call method, comprises the steps:
Step S100: the user sends the conversation instruction at the GUI layer;
Step S200:VOIP module selects one of them agreement to call out in H323 agreement or Session Initiation Protocol, namely carry out H323 calling or SIP and call out;
Step S300: judge whether access success, if build conversation; Return to if not the VOIP module;
Step S400: need to judge whether handoff protocol, return to if not the failure of GUI layer show Calls, call out if be switched to another agreement, namely carry out SIP calling or H323 and call out, then be back to step S300.
So, in the H323 agreement, go wrong, in the time of can't access success, can be switched to Session Initiation Protocol.
For the signaling process figure of whole dual stack system, also please refer to shown in Figure 3ly, it utilizes VOIP module and server S erver to communicate, if H323 calls out or the SIP access success, if unsuccessfully carry out the protocol switching operation.
In sum, compared with prior art, the present invention is by having added a VOIP module on the basis at Session Initiation Protocol stack and H323 protocol stack, be responsible for the Luo Jie of processing protocol control and protocol switching specially, make between two protocol stacks and can switch mutually at any time, greatly improved the autgmentability of terminal and the stability of connection.
