the IMS domain coloring ring back tone SIP routing trigger brief description:

The IMS domain color ring triggering mainly follows 3GPP 24.182 protocol specification, and adopts the called IMS domain triggering principle, when an INVITE (request) message initiated by the calling IMS domain is sent to the called IMS domain S-CSCF, the called S-CSCF triggers a color ring platform through the iFC (initial Filter Criteria) subscription information of the user, and after the color ring platform processes the call message returns to the S-CSCF, and continues the subsequent call flow. The polyphonic ringtone platform starts a playback flow to a calling user after receiving a called ringing message (180), and initiates a re-INVITE flow to finish media negotiation between a calling party and a called party and finally finish conversation between the calling party and the called party after the called party is off-hook.

in the prior art, a calling user can experience a video color ring only under the condition that the video calls a called video color ring user, so that certain limitation is caused to the popularization of the video color ring. In the technical scheme of the invention, the invention provides the method for calling the called video color ring user by the audio, and the method can also experience the video color ring and improve the application of the video color ring. Based on the existing VoLTE audio color ring back tone call playback flow, the core thought of the technical scheme of the invention is to change the media negotiation between the color ring back tone and the calling terminal and replace the audio media with the video media for renegotiation.

In the technical scheme of the invention, the used Protocol is mainly SDP (Session Description Protocol) which is used for media negotiation between two Session entities and reaches a consistency, belongs to a signaling language family and adopts a text (character) Description form. The SDP networking model is mainly a request/response model (offer/answer), as shown in fig. 1.b, and includes entities of request/response and operation behaviors of different stages, such as an initial negotiation process and a re-negotiation process, and simply introduces meanings of various parameters in a message.

The Offer/Answer model includes two entities, one is a request subject Offer and the other is a response entity Answer, which are logically distinguished and can be converted under certain conditions. For example, if the handset a initiates a media negotiation request, then a is Offerer, whereas if a is a reception request, it is Offerer.

the request message from offer to answer is called request offer, and the content includes the media stream type, the coding set used by each media stream, and information such as IP and port to be used for receiving the media stream. After Answerer receives offer, the message returned to offer is called a response, and the content includes information about the media coding to be used, whether to receive the media stream, and the IP and port for receiving the media stream to offer.

the existing color ring calling process mainly refers to two modes of Gateway Precondition and Gateway no-Precondition, and the main difference is that the Precondition mode needs the cooperation of a terminal and a core network to reserve resources, while the no-Precondition mode does not need. The technical solution of the present invention is described below by way of examples. In the embodiment of the present invention, the RBT AS and the RBT MRS included in the polyphonic ringtone platform are logically two independent individuals, may be implemented AS an integrated entity, or may be implemented AS separate individuals, and are illustrated separately in the following embodiments for description.

(one) Gateway Precondition mode:
