For the call flow in this embodiment, refer to accompanying drawing 2 for details, and the specific steps are as follows:

Step 201, user equipment A initiates a call, and sends an INVITE request message, which includes the Offer SDP of user equipment A;

Step 202. After receiving the INVITE message, the CRS AS inserts the "supported: Relevancy" header field into the INVITE message. It should be noted that the Relevancy option tag is extended by the present invention;

Step 203, if user equipment B supports the association feature, that is, it can recognize the "supported: Relevancy" header field, insert the "supported: Relevancy" header field into the returned 180 response message to indicate that the association feature is supported;

Step 204: After receiving the 180 response message, the CRS AS checks whether it contains the "supported: Relevancy" header field, and if it does not contain it, it does not do any processing; if it contains it, it constructs a new INVITE message, and the INVITE message has The following features:

a. Contains the "Require: Early-Session, Relevancy" header field;

b. The tag value of the From header field is different from the tag value of the From header field in the INVITE message sent by the calling terminal;

c. The value of the Call-ID header field is the same as the value of the Call-ID header field in the INVITE message sent by the calling party, and an indication information parameter of a correlation flag is added after the Call-ID header field: "Relevancy-Flag", and Set its value to 1, so that the Call-ID header field and the indication information parameter of the association flag are jointly used as the indication information of the association flag;

d. The P-Asserted-Identity header field is different from that in the INVITE message sent by the calling party;

e. The message body is the Early-Session Offer SDP of the color tone.

Then, the CRS AS sends the newly constructed INVITE message to the called terminal user equipment B, for setting up a new dialogue (Dialog-1, i.e. dialogue 1 in the accompanying drawing 2) to negotiate the ring tone session;

Step 205: After user equipment B receives the second INVITE, it finds that the value of the indication information parameter of the association flag is 1, then compares the Call-ID header fields of the two INVITE messages, and if they are the same, it can be determined that the two INVITEs are the same The user's call request and color ring service request, so that only one incoming call is displayed, and the local ring tone is suppressed;

Step 206, then user equipment B returns a 18x message for the new INVITE, the message carries the CRS Answer SDP, and its To-tag value is different from the To-tag value of the 180 message returned by UE-B before, thus establishing a separate Dialogue to exclusively negotiate color tone sessions;

Step 207: After receiving the message, the CRS AS completes the color tone session negotiation and instructs the MRF to play the color tone for UE-B;

Steps 208 to 2012: The CRS AS forwards the 180 message of Dialog-2 (that is, dialog 2 in the accompanying drawing 2) to the user equipment A, and the user equipment A returns the confirmation message PRACK to the 180 message; the user equipment B returns the PRACK message to the PRACK message. Response message 200OK (PRACK); It should be noted that step 208 can also occur before step 204;

Step 2013～Step 2021: The called party picks up the phone, and user equipment B sends an off-hook message 200OK (INVITE), which carries UE-B Answer SDP, which is used to answer UE-A Offer; CRS AS receives 200OK (INVITE) Afterwards, instruct MRF to stop playing the CRS, and send a CANCEL message to user equipment B to terminate Dialog-1, and then forward 200OK (INVITE) to user equipment A; user equipment B returns a response message 200OK (CANCEL) to the CANCEL message; User equipment A returns an acknowledgment message ACK, and CRS AS forwards the ACK to user equipment B; then the caller and the called party enter into a normal call process.

Optionally, step 2016 and step 2018 in the accompanying drawing 2 may not be required, but the called terminal sends a 4xx error response message, such as 486busy, for Dialog-1 while off-hook sending 200OK (INVITE), so that CRS AS terminates Dialog-1.

In the embodiment of the present invention, there are other options for the selection of signaling messages: that is, after receiving the INVITE sent by the calling party, the CRS AS does not generate a new INVITE message, but sends an INFO message carrying the CRS Offer SDP to the called party. , MESSAGE, or OPTIONS messages, the called terminal carries CRS Answer SDP in the returned 200OK message, thus completing the early media negotiation.

In the embodiment of the present invention, there are other options for the realization of the indication information of the association flag: that is, an indication information header field of the association flag is extended in the new call request message, so that the indication information header field of the association flag The value of is the same as the value of the Call ID header field of the call request message that needs to be associated.

This embodiment is only for the situation of the multimedia color tone service, mainly after the CRS AS confirms that the called terminal supports the associated feature, it sends an INVITE message associated with the original INVITE to establish an independent dialogue to negotiate the early media of the multimedia color tone, This embodiment requires that the called terminal can support the association feature.

The second embodiment provided by the present invention provides another method flow for realizing multimedia color vibration, including:

First, the application scenario is as follows: In an IMS network, user A subscribes the multimedia ring back tone service for user B, and user B subscribes the multimedia ring back tone service for user A. When user A calls user B, the multimedia CRBT server plays the multimedia CRBT for user B, and the multimedia CRBT server plays the multimedia CRBT for the calling user. After the called user B picks up the phone to answer the call, both the multimedia ring tone and the multimedia ring tone stop playing, and the caller and the called party continue the conversation;

The schematic diagram of the networking structure of this embodiment is shown in Figure 3, specifically as follows:

Compared with the networking structure in Embodiment 1, only a multimedia ring back tone server 316 has been added in the accompanying drawing 3, and all the others are identical, and will not be repeated here; multimedia ring back tone server 316: CATAS (Customized Alerting Tone Application Server, multimedia ring back tone The Application Server (AS) is a server in the IMS network that provides IM (IP Multimedia) value-added services for users, and may be located in the user's home network or provided by a third party. CAT AS is mainly used to provide CAT business logic and control MRF to play media resources.

For the call flow in this embodiment, refer to accompanying drawing 4 for details, and the specific steps are as follows:

Step 401, user equipment A initiates a call, and sends an INVITE request message, which includes the Offer SDP of UE-A;

From step 402 to step 403, after receiving the INVITE message, the CRS AS inserts the "supported: Relevancy" header field into the INVITE message. It should be noted that the Relevancy option tag is extended by the present invention, and the CRS AS forwards the INVITE message to the user equipment B;

Step 404: If user equipment B supports the association feature, that is, it can recognize the "supported: Relevancy" header field, insert the "supported: Relevancy" header field into the returned 180 response message to indicate that the association feature is supported;

Step 405, after the CAT AS receives the 180 message, it converts 180 into 183, and inserts the "Require: Early-Session" header field and the CAT Offer SDP message body into the message;

Step 406, after the CRS AS receives 183, check whether it contains the "supported: Relevancy" header field, if not, do nothing; if it does, construct a new INVITE message, and the INVITE message has the following characteristics :

a. Contains the "Require: Early-Session, Relevancy" header field;

b. The tag value of the From header field is different from the tag value of the From header field in the INVITE message sent by the calling terminal;

c. The value of the Call-ID header field is the same as the value of the Call-ID header field in the INVITE message sent by the calling party, and an indication information parameter of a correlation flag is added after the Call-ID header field: "Relevancy-Flag", and Set its value to 1, so that the Call-ID header field and the indication information parameter of the association flag are jointly used as the indication information of the association flag;

d. The P-Asserted-Identity header field is different from that in the INVITE message sent by the calling party;

e. The message body is the Early-Session Offer SDP of the color tone.

Then, the CRS AS sends the newly constructed INVITE message to the called terminal user equipment B to set up a new dialogue Dialog-1, namely dialogue 1 in the accompanying drawing 4, to negotiate the ring tone session;

Since the P-Asserted-Identity header field in the newly constructed INVITE message is different from that in the INVITE sent by user equipment A, when passing through the S-CSCF of the called network, according to the iFC policy, it will not be routed to the CAT AS, but is directly forwarded to user equipment B;

From step 407 to step 408, after user equipment B receives the second INVITE, it finds that the value of the indication information parameter of the association flag is 1, then compares the Call-ID header fields of the two INVITE messages, and if they are the same, it can be determined that the two INVITE is the call request and the multimedia color ring service request of the same user, so that only one incoming call is displayed and the local ring tone is suppressed; then user equipment B returns an 18x message for the new INVITE, which carries the CRS Answer SDP, and its The To-tag value is different from the To-tag value of the 180 message returned by UE-B before, thus establishing a separate dialogue to specifically negotiate the multimedia ring tone session;

Step 409: After receiving the message, the CRS AS completes the color tone session negotiation and instructs the MRF to play the color tone for UE-B;

From step 4010 to step 4017, the CRS AS forwards Dialog-2 to user equipment A, that is, the 183 message of dialog 2 in Figure 4; after receiving the 183 message, user equipment A returns a PRACK message carrying CAT Answer SDP, CAT AS After receiving the message, extract the CAT Answer SDP therein, complete the negotiation of the early media of the CRBT, then forward the empty PRACK message to the user equipment B; the user equipment B returns a response message 200OK (PRACK) to the user equipment A; The CAT AS instructs the MRF to play the CRBT for the user equipment A;

Note: the action of step 4010 can also occur before step 4006;

Step 4018 to step 4029, called off-hook, user equipment B sends off-hook message 200OK (INVITE), carrying user equipment B Answer SDP in the message, for answering user equipment A Offer; CAT AS after receiving 200OK (INVITE) , instruct MRF to stop playing CAT; after receiving 200OK (INVITE), CRS AS instructs MRF to stop playing CRS, and sends a CANCEL message to user equipment B to terminate Dialog-1, and then forwards 200OK (INVITE) to user equipment A, User equipment B returns a response message 200 OK (CANCEL) to the CANCEL message, and user equipment A returns an acknowledgment message ACK after receiving 200 OK (PRACK), and then the caller and the called party enter into a normal conversation process.

Optionally, step 2016 and step 2018 in the accompanying drawing 2 may not be required, but the called terminal sends a 4xx error response message, such as 486busy, for Dialog-1 while off-hook sending 200OK (INVITE), so that CRS AS terminates Dialog-1.

In the embodiment of the present invention, there are other options for the selection of signaling messages: that is, after receiving the INVITE sent by the calling party, the CRS AS does not generate a new INVITE message, but sends an INFO message carrying the CRS Offer SDP to the called party. , MESSAGE, or OPTIONS messages, the called terminal carries CRS Answer SDP in the returned 200OK message, thus completing the early media negotiation.

In the embodiment of the present invention, there are other options for the realization of the indication information of the association flag: that is, an indication information header field of the association flag is extended in the new call request message, so that the indication information header field of the association flag The value of is the same as the value of the Call ID header field of the call request message that needs to be associated.

This embodiment is the situation that the color ring back tone and the ring tone service exist at the same time, and the color ring tone service adopts the early-session mode, and it can be seen that there is no interaction between the color ring tone and the color tone service, so that the existing technology does not appear Double SDP problem.
