The RTP media stream is transmitted between the MGWs, the MGW and the MS, and the MSC server interacts with the MGW using the H.248 protocol. The system shown in Figure 3 constitutes the implementation system of the BICC CRBT IVR service. The system can be applied to the 3G R4 network based on the BICC protocol to implement the CRBT IVR service, including the CRBT IVR to the attendant service. 4 is a flowchart of a method for implementing a BICC CRBT IVR service according to an embodiment of the present invention. The implementation may be applied to a 3G R4 network based on the BICC protocol. As shown in FIG. 4, the process includes the following steps: Step S402 After receiving the IVR call request (including the IVR access code) of the calling user, the core network element on the calling side initiates a media negotiation process with the MS, where, in the media negotiation process, before the BICC signaling The machine converts the BICC protocol message sent by the core network element on the calling side into an internal interface protocol message and sends it to the AS, and converts the internal interface protocol message from the AS into a BICC protocol message and sends the message to the core network element on the calling side. Step S404, the core network element on the calling side establishes a bearer connection with the MS; in step S406, the MS performs a sound collection and reception on the calling user.

FIG. 5 is a flowchart of a method for implementing a BICC CRBT IVR service according to a preferred embodiment of the present invention. As shown in FIG. 5, in actual application, after step S406, the following steps may also be included (steps S408-S412): S408: When the calling user selects to switch to the operator according to the playback of the MS, the AS notifies the BICC signaling front-end machine to call the attendant; Step S410: The MS performs media negotiation with the core network element on the side of the called (in the actual application, the called party, the operator) through the BICC signaling front-end machine, and establishes a bearer with the core network element on the called side. A media connection may be performed between the core network element and the MS based on the BIBCP (BICC IP Bearer Control Protocol) protocol; the established bearer connection may be a Nb UP (User Plane user plane) connection, MS And the core network element transmits the RTP media stream on the connection. Step S412, the AS creates a conference on the MS, and joins the attendant and the calling user into the conference, so that the calling user and the attendant make a call. Obviously, the connection relationship between the BICC signaling front-end device in the method embodiment of FIG. 4 and FIG. 5 and the core network element on the calling side or the core network element and the AS on the called side is as shown in FIG. 3 . The above embodiment implements the CRBT IVR service through the BICC signaling front-end, the SIP-based AS, and the MS. The BICC signaling front-end machine is configured to receive and parse the BICC protocol message sent by the MSC server, convert the BICC protocol message into an internal interface protocol message, send the message to the AS, or receive the internal interface protocol message sent by the AS, and connect the internal interface. The protocol message is converted into a BICC protocol message and sent to the core network element; the AS implements the service logic of the CRBT IVR service, and calls the MS or the attendant; the MS performs the functions of playing, receiving, and receiving according to the indication of the AS. In combination with the implementation system of the BICC CRBT IVR service shown in FIG. 3, in the actual implementation process, the system implements a call flow of the CRBT IVR to the attendant service. As shown in FIG. 6, the call process includes the following steps: Step 1 The calling user dials the IVR access code and triggers the MSC server on the calling side. The MSC server on the calling side sends an IAM (Initial Address Message) to the BICC signaling front-end machine, where I The AM carries the SDP (Session Description Protocol) information of the MGW (Media GateWay) on the calling side (ie, SDP1 in FIG. 6), and the SDP information follows the IPBCP (BICC IP Bearer Control Protocol, BICC). The IP bearer control protocol protocol, and the SDP information includes information such as the media type, connection address, port number, and encoding of the MGW on the calling side. Step 2: After receiving the IAM, the BICC signaling front-end machine finds that it is an IVR. Flow, sending an internal message triggering the call (ie, internal message 1 in FIG. 6) to the AS to trigger the IVR service on the AS; Step 3: When the AS receives the internal message of the triggered call sent by the BICC signaling front-end, it triggers the CRBT IVR service, and the AS carries the SDP information of the MGW on the calling side to call the MS (that is, sends a call request (INVITE) to the MS. Preferably, the AS carries the SDP information of the MGW on the calling side to call the MS. The AS sends an INVITE to the MS, where the INVITE carries the SDP1. Step 4: The MS returns a 200 INVITE (Call Answer) message, where the 200 INVITE carries the SDP information of the MS (ie, the SDP MS 1 in FIG. 6), the SDP information follows the IPBCP protocol, and includes the media type of the MS, Connect the address, port number, and encoding information; Step 5, the AS sends an ACK to the MS; Step 6, the AS sends an internal message to the BICC signaling front-end (ie, the internal message 2 in Figure 6), indicating the BICC signaling The MSC server on the calling side is returned to the APM (Application Transport Mechanism) and carries the SDP information of the MS in the APM. Step 7, the BICC signaling front-end machine is sent to the MSC server on the calling side. The APM is sent, and the SDP information of the MS is carried in the APM. At this time, through the foregoing steps 1-7, the MGW and the MS on the calling side complete the media negotiation. The above steps 1-7 correspond to step S402 in Figs. 4 and 5. After the tenth office is completed, the MGW on the calling side actively initiates the Nb UP connection between the MS and the MS. This step 4 corresponds to step 4 of S4 in FIG. 4 and 5. Step 8: After the connection is successfully established, the MSC server on the calling side sends a COT (Continuity) message to the BICC signaling front-end, indicating the Nb UP between the MGW and the MS on the calling side.

Step 41: The AS sends an INFO to the MS to stop the playback of the calling user. In step 42, the AS sends an INFO to the MS, and the calling user is sent. Join the meeting. At this point, both the calling user and the attendant join the conference, and the MS completes mixing with the calling side MGW and the called side MGW, so that the calling user and the attendant make a call. The above steps 40-42 correspond to step S412 in FIG. At this point, the CRBT IVR transfer operator service is completed. The internal message in the embodiment shown in Figure 6 is the internal interface protocol message described above. From the above description, it can be seen that the present invention achieves the following technical effects: By setting a BICC signaling front-end machine between the core network element and the AS, for converting between the BICC protocol and the internal interface protocol, The integration of the BICC protocol and the SIP protocol is realized, so that the ICR and the BICC signaling front-end device can be used to implement the CRBT IVR service on the 3G R4 network, and the existing broadband CRBT system cannot be directly solved.
