Embodiment
As shown in Figure 1, in first embodiment of multiprotocol support system of the present invention, Media Resource Server 10 comprises communication interface 11, MGCP protocol stack 12, MGCP protocol stack adaptation layer 13, Session Initiation Protocol stack 14, Session Initiation Protocol stack adaptation layer 15, H.248 protocol stack 16, H.248 the protocol stack adaptation layer 17, and resource management module 18 etc., wherein the MGCP protocol stack 12, Session Initiation Protocol stack 14, H.248 protocol stack 16 is connected with communication interface 11 respectively, MGCP protocol stack adaptation layer 13, Session Initiation Protocol stack adaptation layer 15, H.248 17 of protocol stack adaptation layers successively with MGCP protocol stack 12, Session Initiation Protocol stack 14, H.248 protocol stack 16 connects, in addition MGCP protocol stack adaptation layer 13, Session Initiation Protocol stack adaptation layer 15, H.248 protocol stack adaptation layer 17 also is connected with resource management module 18 respectively.
MGCP protocol stack 12, Session Initiation Protocol stack 14, H.248 protocol stack 16 is respectively applied for the message of decoding different agreement, respectively with MGCP agreement, Session Initiation Protocol, H.248 protocol massages resolves to concrete operational order, for example connect, delete connection, playback, record, collect the digits and video playback etc.Each protocol stack also is used for different agreement operational order (the discernible message body of each protocol stack) is encoded to different protocol massages (for example MGCP protocol stack 12 is the MGCP message with the MGCP operation instruction to code) and by communication interface 11 message is sent to corresponding control appliance.
With MGCP protocol stack 12, Session Initiation Protocol stack 14, MGCP protocol stack adaptation layer 13, Session Initiation Protocol stack adaptation layer 15 that H.248 protocol stack 16 is corresponding, H.248 protocol stack adaptation layer 17 can be converted into decoded operational order the message with unified message structure body, promptly by MGCP protocol stack adaptation layer 13, Session Initiation Protocol stack adaptation layer 15, H.248 the message that generates respectively of protocol stack adaptation layer 17 has unified message structure body, thereby can handle by uniform resource management module 18.Because the parameter that same a kind of operation (as MGCP playback and SIP playback) of different agreement parses all is similar (as playback file number, playback filename, playback number of times, playback interval etc.), so the protocol stack adaptation layer can be masked the difference of agreement, be converted to message and handle, the underlying resource that different like this agreements just can the share media resource server (playback, record, collect the digits, meeting and video resource etc.) by resource management module 18 with unified message structure.In the present embodiment, this message with unified message structure body comprises endpoint number, operational order type and operating parameter etc.In addition, the message with unified message structure body also can comprise call-index sign etc.
For example create when connecting, MGCP protocol stack adaptation layer 13 has with the public information that the protocol stack adaptation layer 15 of SIP is extracted: endpoint number, medium property that is connected and the transceiver mode that is connected etc., these public informations are configured to have the message of unified message structure body, are handed down to resource management module 18.It is the calling of MGCP or the calling of SIP that resource management module 18 need not be distinguished this again, and (for example search idle connection, issue for the bottom module and create bind command etc.) all handled in all callings in the same way.
The protocol stack adaptation layer also is used for and will is the message body that can discern of corresponding protocol stack from the response message of the unified message structure body of having of resource management module 18 or operation result uploading message transformation and the message body that generates is sent to the corresponding protocols stack, for example MGCP protocol stack adaptation layer 13 is a MGCP protocol message body with message transformation, and Session Initiation Protocol stack adaptation layer 15 is Session Initiation Protocol message body with message transformation then.
In the present embodiment, resource management module 18 has a uniform resource management strategy, so that the calling of various control protocols can not influence each other, for example can distinguish protocol massages according to the endpoint number in the protocol massages is that MGCP calls out or SIP calls out.For MGCP called out, each end points all had a unique endpoint number, and SIP calls out then not to be had, and has only calling ID.In the present embodiment, the Session Initiation Protocol stack adaptation layer 15 of Media Resource Server 10 can be called out to SIP and be divided an endpoint number.The endpoint number of MGCP is since 0, because the connection of Media Resource Server support at present is far less than 30000 the tunnel, so the endpoint number of SIP can be since 30000, whenever there is a new end points just to add one, can not clash and obscure (other agreements are handled with similar approach) with the calling terminal period that guarantees different control protocol.Thereby return response or when reporting operating result at control appliance, can send to corresponding protocols stack adaptation layer according to the message that port numbers will have a unified message structure body to correspondence.For example, behind the operational order of resource management module 18 complete MGCP agreements, the response message that will have unified message structure body is sent to MGCP protocol stack adaptation layer 13.
Certainly, can comprise other protocol stack and corresponding protocols stack adaptation layer in the Media Resource Server 10, to support other control protocols.Certainly, Media Resource Server 10 also can only comprise MGCP protocol stack 12, Session Initiation Protocol stack 14, reach corresponding MGCP protocol stack adaptation layer 13, Session Initiation Protocol stack adaptation layer 15, thereby supports the control command of MGCP agreement and Session Initiation Protocol.
As shown in Figure 2, be the flow chart of multi-protocols support method of the present invention.
At first, Media Resource Server 10 decodings are from the message of control appliance.Message that it receives from control appliance by communication interface 11 earlier, this message can be MGCP protocol massages, Session Initiation Protocol message, message etc. H.248; Communication interface 11 sends to the corresponding protocols stack according to the port point of the message that receives with the message that receives, if for example the MGCP message then sends to MGCP protocol stack 12, if the SIP message then sends to Session Initiation Protocol stack 14.The protocol stack that receives message is decoded as message concrete operational order and is sent to corresponding protocols stack adaptation layer (step S21).
The protocol stack adaptation layer is converted to the message with unified message structure body with operational order, and sends to resource management module 18.This message with unified message structure comprises: the endpoint number, operational order type and the operating parameter that are used to identify the message source.(step S22).
As shown in Figure 3, be processing messages and return the flow chart of response of step among Fig. 2.Resource management module 18 is carried out above-mentioned message with unified message structure body, for example searches idle connection, issues (step S31) such as establishment bind commands for the bottom module.
The protocol stack adaptation layer will from the response message of the unified message structure body of having of resource management module 18 or to report the operating result message conversion be the message body that protocol stack can be discerned, and send corresponding protocols stack (step S33) to.Protocol stack is converted to the message (step S34) of corresponding agreement with message body, and sends to the control appliance (step S35) of correspondence by communication interface 11.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
