Description
Technical field
The present invention relates to communication technique field, relate in particular to a kind of exchange method, Apparatus and system of separation architecture dual-tone multi-frequency.
Background technology
Multimedia communications system is meant can provide Multimedia session, as the network system of audio frequency and video communication.There is multiple multimedia communications system at present, comprises that H.324, H.245, H.223 employing waits the H.324 network of agreement; Adopt H.323, H.225.0, H.245, the H.323 network of RTP (RTP)/RTCP agreements such as (RTCP Real-time Transport Control Protocols); Adopt SIP (conversation initialized protocol), protocol of I MS (IP Multimedia System) networks such as SDP (Session Description Protocol), RTP/RTCP or the like.
Intercommunication between the different multimedia communication system need realize the intercommunication of signaling and medium, is generally cooperated by medium control device under the separation architecture and medium processing device and finishes.Medium control device and medium processing device comprise: MGCF (the MGCF)-IM-MGW (IP multimedia-media gateway) in the MGC among the NGN (Media Gateway Controller)-MGW (media gateway), WCDMA mobile network's MSC Server (Mobile Switching Center Server)-MGW (media gateway), the IMS network, the MRFC (media resource function control) in the IMS network-MRFP (media resource function processing) etc.Use MGC and MGW general designation herein as medium control device and medium processing device.MGC finishes and calls out control, realizes the intercommunication of signaling, and indication MGW operation media resource.MGW provides media resource, and operates media resource according to the indication of MGC, realizes the intercommunication of medium.By the medium control protocol, carry out alternately between MGC and the MGW such as agreement H.248.
With IMS network and CS (circuit switching) network interworking is example, network model as shown in Figure 1, IMS is by MGCF (MGCF) and IM-MGW (IP multimedia-media gateway) entity and CS network interworking, MGCF controls IM-MGW, finish simultaneously call out between SIP and BICC (carrying control separates)/ISUP relevant signaling alternately, realize the chain of command intercommunication, IM-MGW finishes user's face intercommunication of IMS network and CS network.
In the multimedia interconnection network, IMS and CS can pass through the control of the mutual realization of DTMF (dual-tone multifrequency) to business.For example: CS user and IMS user can be by operating the triggering dtmf signal to terminal, IM-MGW reports MGCF after detecting described dtmf signal, thereby realize the control to business.MGCF can will indicate IM-MGW by sending IMS side or CS side in being with to from the dtmf signal of signaling plane, also can send opposite side to by in being with from the dtmf signal indication IM-MGW of a certain side.When IMS and CS network carried out multimedia business intercommunication, H.245 message can terminate on MGC, also can terminate on MGW.H.248.1 define " BasicDTMF Generator Package " bag in and be used for playing DTMF.
The detected DTMF of MGW can directly handle on MGW, also can report MGC, waits the indication of MGC, introduces several situations of MGC indication MGW operation dtmf signal below respectively:
1, MGC indication MGW is with the dtmf signal transparent transmission:
When IM-MGW detects dtmf signal from the Media Stream that the CS side is sent, IM-MGW directly changes into the RFC2833 incident and is transmitted to the IMS side;
When IM-MGW detects the dtmf signal that transmits by the RFC2833 incident from the Media Stream that the IMS side is sent, IM-MGW directly plays DTMF to the CS side;
2, report after MGC indication MGW detects dtmf signal:
MGC can indicate MGW to detect the DTMF incident, and H.248.1 " DTMF detectionPackage " defined the detection incident of a series of DTMF, and MGC can wrap by this and report MGC after indicating MGW to detect DTMF.
MGC can indicate the MGW detection to receive H.245 and report after the UserInput Indication message.
When IM-MGW detects dtmf signal from the Media Stream that the CS side is sent, MGW reports detected dtmf signal to MGC, and indication MGW transmitted DTMF to the IMS side by the RFC2833 incident after MGC received the message that MGW reports; When IM-MGW receives the DTMF that transmits by UserInputIndication message H.245 from the CS side joint, MGW reports the H.245 message that receives to MGC, and indication MGW transmitted DTMF to the IMS side by the RFC2833 incident after MGC received the message that MGW reports.
When IM-MGW detects the dtmf signal that transmits by the RFC2833 incident from the Media Stream that the IMS side is sent, MGW reports detected dtmf signal to MGC, and indication MGW play DTMF to the CS side after MGC received the message that MGW reports;
3, MGC indication MGW sends dtmf signal:
If MGC need indicate MGW to send dtmf signal to the CS side, then MGW can only play DTMF to the CS side; If MGC need indicate MGW to send dtmf signal to the IMS side, then MGW can transmit dtmf signal by the RFC2833 incident.
The shortcoming that prior art is handled dtmf signal is:
1) forward direction CS side sends DTMF and adopts the mode of playing DTMF, because the CS side adopts the audio coding decoding of compression, this directly to transmit the mode of DTMF by audio stream very unreliable, the situation of omission, false retrieval might occur.
2) MGC can't indicate MGW to be directly changed into H.245UserInput from the detected DTMF of IMS side Indication message sends to the CS side; Like this, can only can there be the risk of omission, false retrieval in MGW by audio stream to CS side transmitting DTMF signals.
3) at present agreement is not clearly described MGW and is received by how this handles behind the DTMF that H.245 UserInputIndication message transmits from the CS side joint.
4) MGW receives from the CS side behind the DTMF that transmits by UserInput Indication message H.245 if report MGC, can only report H.245 UserInput Indication message of whole piece, inconsistent with MGW termination thought H.245, MGC also needs to carry out H.245 protocal analysis after receiving such reporting, such one H.245 UserInput Indication message on MGW and MGC, all need to handle, make like this and handle quite complexity.
