Embodiment 1

[0069] image 3 It shows the flow chart of the implementation method of the single-dialogue chromatic image service according to the preferred embodiment 1 of the present invention, and describes that the calling party calls the called party, and the chromatic image server plays the chromatic image to the called party during the calling process. When the user answers, When the chromatic image server initiates media renegotiation, the process is as follows:

[0070] Step 301, UE-A initiates a call request, carrying an SDP request, such as sending an INVITE (invitation) message, carrying an SDP request in the message body, and the message arrives at the chromatic image AS via the forwarding of the P-CSCF and the S-CSCF;

[0071] Step 302, the chromatic image AS calls the chromatic image media server without any SDP information, and the message passes through the S-CSCF;

[0072] Step 303, the chromatic image media server answers the call, such as sending a message starting with...

Embodiment 2

[0095] Figure 4 Shows the flow chart of the implementation method of the single-dialogue chromatic image service according to the preferred embodiment 2 of the present invention, describes that the calling party calls the called party, the chromatic image server plays the chromatic image to the called party during the calling process, and when the user answers, When the chromatic image server initiates media renegotiation, the process is as follows:

[0096] Step 401, UE-A initiates a call request, carrying an SDP request, such as sending an INVITE (invitation) message, carrying an SDP request in the message body, and the message arrives at the chromatic AS through the forwarding of the P-CSCF and the S-CSCF;

[0097] Step 402, the chromatic image AS receives the call request, calls UE-B, such as sending an INVITE message, the message body carries the SDP request of the calling party, and the message passes through the S-CSCF;

[0098] Step 403, UE-B receives the call messag...

Embodiment 3

[0120] Figure 5 Shows the flow chart of the implementation method of the single-dialogue chromatic image service according to the preferred embodiment 3 of the present invention, describes that the calling party calls the called party, the chromatic image server plays the chromatic image to the called party during the calling process, and when the user answers, When the chromatic image server initiates media renegotiation, the process is as follows:

[0121] Steps 501-409, and Figure 4 Steps 401-409 in are the same;

[0122] Step 510, the chromatic image AS sends a temporary response message to the calling party, such as sending a message starting with "1" such as a "183 Session Progress" message, and the message body carries the SDP response of the called party in step 503, in order to prevent UE- A data transmission error occurs, the chromatic image AS can add a zero bandwidth flag in the SDP response of the called party, and the message reaches UE-A via S-CSCF and P-CSC...

Abstract

The invention provides a method for realizing single-dialog color image service which comprises that: a color image application functional entity adopts a single-dialog mode to play the color images to the called party after receiving calling requirements from a calling party, the called party initiates responding information to respond the calling requirements, the color image application functional entity transmits an SDP of the calling party to the called party after receiving the responding information and before transferring the responding information, the called party transmits the SDP of the called party to respond the SDP of the calling party, the color image application functional entity transmits the SDP to the calling party after receiving the SDP of the called party, and builds a session between the calling party and the called party through utilizing the SDP of the calling party and the SDP of the called party.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing a single-dialogue color image service. Background technique [0002] IP (Internet Protocol, Internet Protocol) multimedia subsystem (IPMultimedia Core Network Subsystem, IMS for short) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3GPP for short). An open and flexible service environment supports multimedia applications and can provide users with rich multimedia services. [0003] In the IMS service system, the control layer and the service layer are separated, and the control layer does not provide specific services, but only provides necessary functions such as triggering, routing, and charging to the service layer. The service trigger and control function in the control layer is Call Session Control Function (Call Session Control Function, referred to as CSCF), which is divided into three types: Proxy (P-CSCF), Interro...
