Problems solved by technology

[0031] As can be seen from the above process, in the prior art, when the color ring server and the color image server exist at the same time, the color ring image information cannot be played normally to the calling party and the called party; in addition, after the called party answers the call , it takes a lot of signaling interaction to actually start the call, which affects the user experience

Embodiment Construction

[0065] The present invention will be described in detail below with reference to the drawings and embodiments.

[0066] figure 2 It is the flow chart of the implementation method of the single-dialogue color ring back tone and color image service in the first embodiment of the present invention; The party's SDP request is replaced by a CRBT SDP request, and subsequent processing is performed), the CRBT server does not execute the CRBT business logic of a single conversation (that is, the SDP response of the called party is not replaced with a CRBT SDP response, and other subsequent processing) , but to execute the logic of the color ring business in other ways or not to execute the color ring business, which specifically includes the following steps:

[0067] Step 201, UE-A initiates a call request, carrying UE-A's SDP request (SDP request 1); for example, sending an INVITE (invitation) message, carrying SDP request 1 in the message body of the message, and the message arriv...

Abstract

Disclosed is an implementation method for single session coloring ring back tone(CRBT) / polychrome business, which includes that: when a polychrome application server adds the Session Description Protocol (SDP) request of the polychrome business into the message sent to the called party from the calling party, or when the SDP request of the message is altered into the SDP request of the polychrome business, polychrome business identifier can be added into the message and then transmitted to the called party; a CRBT application server receives the message and then determines whether the received message carries the identifier or not; if the message carries the identifier, the CRBT business logic in the single session mode can not be unexecuted in the following calling setup procedure. Through adding the procedure that whether other network elements execute the single session CRBT / polychrome business or not is determined, the implementation method for single session CRBT / polychrome business avoids the problem that the CRBT / polychrome business message is not played to users, and greatly reduces the signaling interactions after the called part answers the call so as to improve the user experience at the same time.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method for realizing color ring and color video services in an IP (Internet Protocol, Internet Protocol) multimedia subsystem. Background technique [0002] IP Multimedia Core Network Subsystem (IMS for short) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3GPP for short), which builds 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 the call session control function (Call Session Control Function, referred to as CSCF), which is divided into three typ...
