Problems solved by technology

[0004] Since the multimedia ring back tone server CATAS / MRF (Customized Alerting Tone Application Server / Multimedia Resource Function) is used as the conference center to perform mixing processing when the ring tone / ring tone continues to be played during the calling process, the call media stream of the calling party needs to Transit via CAT AS / MRF, which increases the load of CAT AS / MRF itself, which is prone to bottleneck effect

Embodiment 1

[0064] Application scenario:

[0065] The called terminal UE-B has subscribed to the calling terminal UE-A as a multimedia ring back tone, and the multimedia ring back tone includes both an audio ring back tone and a video ring back tone. When UE-A makes a video call to UE-B, the multimedia ring back tone server CAT AS / The MRF first plays the multimedia CRBT for UE-A. In addition, UE-B's personalized settings are pre-configured in CAT AS, that is, when UE-B only wants to have an audio call with UE-A, it will continue to play silent video for UE-A during the call. ring tones.

[0066] Network structure:

[0067] The networking structure of the application of the method for playing video ring back tones in the embodiment of the present invention is as follows: image 3 As shown, the network structure includes the calling terminal UE-A, the called terminal UE-B, the multimedia ring back tone server CAT AS / MRF and several levels of application entities. UE-A passes through th...

Embodiment 2

[0091] Application scenario:

[0092] The application scenario of Embodiment 2 is basically the same as the application scenario of Embodiment 1, the difference lies in the personalized settings of UE-B pre-configured in CATAS, that is: when UE-B only wants to receive UE-A video in one direction During a call, that is, when UE-B only receives UE-A's video information and does not send its own video information to UE-A, it will continue to play a silent video ring back tone for UE-A during the call between the calling party and the called party.

[0093] Network structure:

[0094] The networking structure of the second embodiment is the same as that of the first embodiment.

[0095] Implementation process:

[0096] like Figure 7 As shown, the implementation process of Embodiment 2 includes the following steps:

[0097] S701. The CAT AS / MRF receives the INVITE message sent by UE-A, and the INVITE message includes UE-A's call request message UE-A Offer;

[0098] S702, the ...

Embodiment 3

[0127] Application scenario:

[0128] The application scenario of Embodiment 3 is basically the same as that of Embodiment 1, except that the personalized settings of UE-B pre-configured in the CAT AS, that is, when UE-B only wants to communicate with UE-A During a call, or when UE-B only wants to receive a video call from UE-A in one direction, it will continue to play a silent video ring back tone for UE-A during the call between the calling party and the called party.

[0129] In addition, UE-A sends an INVITE message to UE-B, and the INVITE message carries the request message UE-A Offer of the calling terminal, so as to initiate a call establishment request to UE-B. Wherein, the call request message UE-A Offer includes both an audio stream and a video stream.

[0130] Network structure:

[0131] The networking structure of the third embodiment is the same as that of the first embodiment.

[0132] Implementation process:

[0133] like Figure 12 As shown, the implement...

Abstract

The embodiment of the invention discloses a method for playing a video CRBT (color ring back tone), a multimedia CRBT server and user equipment, relating to the technical field of communications and aiming to reduce the load of a multimedia CRBT server. The method for playing a video CRBT comprises the following steps: receiving a session response sent by a called terminal; modifying video stream consultation information in the session response when determining that the session response contains an identification of only receiving bidirectional audio streams or unidirectional video streams; sending the session response with the modified video stream consultation information to a calling terminal; receiving acknowledgment information sent by the calling terminal; and continuously playing the video CRBT for the calling terminal in the conversation process of the called terminal and the calling terminal. The method, multimedia CRBT server and user equipment disclosed by the embodiment of the invention can be applied to playing the video CRBT for the calling terminal continuously in the conversation process of the called terminal and the calling terminal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for playing video ring back tones, a multimedia ring tones server and user equipment applied in the technical field of communication. Background technique [0002] At present, the multimedia ring tone service includes: multimedia ring back tone, multimedia ring tone and multimedia background tone. The ring back tone is also called the multimedia ring back tone, that is, when the calling party dials the called party, the calling party can enjoy the multimedia ring back tone before the called party picks up the phone to answer the call. The ringing tone is also called multimedia ring tone, that is, when the calling party dials the called party, the called party can enjoy the multimedia ringing tone before the called party picks up the phone to answer the call. The background sound is also called multimedia color image, that is, during the call between the ca...
