Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, a kind of exchange method flow chart based on the SIP-C agreement for the embodiment of the invention comprises:
Step S101, request is set up User Agent Client to the connection of User Agent Server, and the request following a kind of mode of employing or following several mode make up and connect:
1., connect in a kind of mode of bearing protocol, success or not does not re-use other agreement and connects, the agreement that described bearing protocol relies on when being the SIP-C protocol application, and such as the Transmission Control Protocol of transport layer, HTTPS agreement and the http protocol of application layer;
2., be linked in sequence in the mode of multiple bearing protocol, and only in a kind of bearing protocol connected mode under just attempting after the previous mode connection failure, the wherein i.e. success of any successful connection, all connect just failure of all failures;
3., with multiple bearing protocol mode parallel join, when wherein cancelling other connection after the successful connection of a kind of bearing protocol mode.
Realize above-mentioned three kinds of connected modes, need to bearing protocol commonly used be encapsulated, and take out unified connecting interface, realized the SIP-C protocol stack of three-decker for the present embodiment that achieves the above object, as shown in Figure 2, three levels are: interface layer, realization layer and encapsulated layer.
1, interface layer
ISipcConnect is the interface definition layer of SIP-C assembly, has defined unified SIP-C component interface, and defining unified SIP-C component interface is for the compatible multiple bearing protocol of this programme energy, realizes that every kind of SIP-C assembly of layer all need be realized this interface.
2, realize layer
(1) the SipcTcpConnect SIP-C that is based on the transport layer Transmission Control Protocol realizes, has realized the associative operations such as transmission, reception of SIP-C based on the SIP-C assembly of Transmission Control Protocol;
(2) the SicpcHttpsConnect SIP-C that is based on application layer HTTPS agreement realizes, has realized the associative operations such as transmission, reception of SIP-C based on the SIP-C assembly of HTTPS agreement;
(3) SipcHttpConnect is based on the SIP-C realization of application layer http protocol, has realized transmission, the reception associative operation of SIP-C based on the SIP-C assembly of http protocol.
The SIP-C assembly of above-mentioned concrete TCP, HTTP and HTTPS agreement is based on the infrastructure component of corresponding operating system (WINDOWS, LINUX or MAC) and realizes.
3, encapsulated layer
Protocol stack SipcStack has encapsulated the SIP-C assembly (SipcTcpConnect) based on Transmission Control Protocol, SIP-C assembly (SipcHttpsConnect) based on the HTTPS agreement, SIP-C assembly (SipcHttpConnect) based on http protocol, unified assembling and parsing SIP-C signaling, unified SIP-C operation-interface externally is provided, the method for above-mentioned customization SAP-C connected mode is provided.SipcStack has also safeguarded a SIP-C request queue, and a SIP-C replys formation, maintaining network operation thread pool, and be responsible for the request on assembling upper strata and resolve replying of bottom, the upper strata is mutual.
Specifically initiated to connect to protocol stack SipcStack by the application program SipcApp among the UAC, user's customizable employing in application program is above-mentioned 1., 2. connect with any mode of being connected in three kinds of connected modes, SipcStack carries out adaptive to agreement, and utilize adaptive successful connecting link SipcTcpConnect, SicpcHttpsConnect or SipcHttpConnect initiation to the connection of server, be preferably and adopt asynchronous system to connect.
Step S102, User Agent Client UAC(User Agent Client) utilize described connection and User Agent Server UAS(User Agent Server) carry out data interaction.Specifically comprise:
UAC utilizes the connection of setting up among the step S101, i.e. one of them transmission request of data of connecting link SipcTcpConnect, SicpcHttpsConnect and SipcHttpConnect.
UAS receives and resolves this request of data, and by protocol stack SipcStack notice application layer process, application layer is carried out different processing according to different requests, also utilizes this connection to send reply data to UAC after the processing;
UAC receives described reply data, and by protocol stack SipcStack notice application layer process, utilizes simultaneously this connection to return and confirm to reply.
The mode of protocol stack SipcStack notice application layer process is overall situation readjustment and local readjustment, and notice only occurs in user's main thread.No matter be that overall situation readjustment or local readjustment all occur at main thread; When the upper-layer user carries out an operation (request), should call at main thread, then this protocol stack can be carried out concrete action at worker thread, adjusts back the user by call back function at main thread again after complete.Overall situation readjustment is for UAS, because UAS and do not know when UAC can ask, so this readjustment must set in advance; Receive the request of UAC as UAS after, will be by overall situation readjustment notice to the upper-layer user; Local readjustment is for UAC, when UAC sends request, a call back function (arranging during request) will be set, and when receiving the replying of UAS, can notify the upper-layer user by this call back function.
Step S103 when data interaction is complete, disconnects above-mentioned connection.
The invention allows for a kind of interactive system based on the SIP-C agreement, as shown in Figure 3, comprising:
Adaptive link block is used for request and sets up User Agent Client to the connection of User Agent Server, and the concrete request following a kind of mode of employing or following several mode make up and connect:
Mode with a kind of bearing protocol connects, and success or not does not re-use other bearing protocol and connects the agreement that described bearing protocol relies on when being the SIP-C protocol application;
Mode with multiple bearing protocol is linked in sequence, and only in a kind of bearing protocol connected mode under just attempting after the previous mode connection failure, the wherein i.e. success of any successful connection, all connect just failure of all failures;
With multiple bearing protocol mode parallel join, when wherein cancelling other connection after the successful connection of a kind of bearing protocol mode;
The data interaction module is used for User Agent Client and utilizes described connection and User Agent Server to carry out data interaction;
Connect the disconnection module, after finishing for data interaction, disconnect.
Above execution mode only is used for explanation the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; in the situation that does not break away from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
