Embodiment Construction

[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] figure 2 It is a schematic flowchart of a method according to an embodiment of the present invention, such as figure 2 As shown, the ringback tone playback control method implemented by this embodiment mainly includes:

[0051] Step 201: During the voice call process, after the server starts to send a ringback tone data packet to the calling terminal according to the ringing message of the called terminal, if it receives the answering message of the called terminal, it forwards the answering message to the calling terminal. After the calling terminal, according to the current switch state of the end-to-end encryption function, a ringback tone data packet is sent to the calling terminal.

[0052] In this step, the starting tim...

Abstract

The present application discloses a method and system for controlling ringback tone playback, wherein the method includes: during a voice call, after the server starts to send a ringback tone data packet to the calling terminal according to the ringing message of the called terminal, if it receives the answering message of the called terminal, after forwarding the answering message to the calling terminal, according to the current switch state of the end-to-end encryption function, a ringback tone data packet is sent to the calling terminal; the calling terminal After starting to input the received ringback tone data packet into the player for playback according to the ringing message, if the answering message is received, after restarting the player, for the received voice data packet, It is judged whether it is a ringback tone data packet, if so, the voice data packet is discarded, otherwise, the voice data packet is input to the player for playback. The application of the technical solution disclosed in the present application can solve the problem of abnormal playback of the ringback tone when the transmission delay is large.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and system for controlling ringback tone playback. Background technique [0002] At present, voice calls or video calls generally have a ringback tone service, that is, after the calling user dials the called user, when the called user rings, the server sends a ringback tone to the calling user. In the implementation scheme of the ringback tone service in the existing system, when the called user presses the answer key, the server will send an answer message to notify the calling user, and the calling user will reply to the corresponding confirmation message after receiving the answer message. The server restarts the player at the same time and stops playing the ringback tone; the server stops sending the ringback tone after receiving the confirmation message replied by the calling user. Below with figure 1 Taking the voice call flow of 3GPP sho...
