Method for playing multimedia color vibration and color ring back tone and application server

Abstract

The invention discloses a method for playing multimedia customized ringing signal (CRS) and ring back tone and an application server. The method comprises the steps that an application server receives an initial call request from a calling terminal, sends the initial call request to a called terminal, receives a temporary response from the called terminal for the initial call request, determinesearly CRS media information according to the temporary response, sends a first updating media session message carrying the early CRS media information to the called terminal, receives a first responsefrom the called terminal, and plays multimedia CRS according to the first response, wherein the initial call request comprises SDP information of the calling terminal, and the first response comprises a CRS media negotiation result between the application server and the called terminal. Thus, the negotiation of the CRS media between the application server and the called terminal and the call media negotiation to be carried out with the calling terminal and the called terminal are in one session, thereby being beneficial to saving network resources, and being capable of realizing the real-timemanagement and control of the CRS service by the application server.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method for playing multimedia ringtones and ringtones, and an application server. Background technique [0002] With the introduction of voice over long term evolution (VoLTE), the quality of voice calls has been significantly improved compared with the 2G and 3G eras. VoLTE can provide high-definition voice calls and video calls. With the upgrading of terminal equipment and core network capabilities, services such as high-definition audio ring back tones and video ring tones have emerged as the times require. The called terminal can play customized ringing signals (customized ringing signals, CRS), also known as color ringing signals, during the ringing phase. vibration. [0003] At present, the color vibration service is usually implemented in the "early session" mode or the "download and play" mode. For the "early session" mode, on the one hand, both th...

AI Technical Summary

Problems solved by technology

For the "early session" mode, on the one hand, both the terminal device and the color vibration application server need to support the "early session" mode. At present, the support rate of the terminal device and the color vibration application server for the "early session" mode is low

On the other hand, when negotiating the color tone media between the terminal device and the color tone application server, it is necessary to establish a new session to carry out the color tone media negotiation, which needs to occupy more network resources

Therefore, the "early session" mode adopted by the color vibration business in the prior art is not conducive to the development of the color vibration business

For the "download and play" mode, the called terminal downloads the multimedia color tone and then plays the color tone content, which is highly dependent on the called terminal, and the called terminal can block the multimedia color tone playback, resulting in The color vibration application server lacks control over the color vibration business, which is not conducive to the development of the color vibration business
