Problems solved by technology

[0005] Since the calling terminal and the called terminal respectively establish data channels with the multimedia server, they need to go through stages such as RRC (Radio Resource Control, radio resource control protocol) connection establishment and PDP (Packet Data Protocol, packet data protocol) context activation. The average delay between RRC connection establishment and PDP context activation is 2 seconds, and playing multimedia information requires high real-time performance. Therefore, when the data channel is established until the calling terminal or called terminal obtains the multimedia information and plays it will cause a large delay

Embodiment 1

[0098] The embodiment of the present invention provides a method for playing multimedia information, see figure 1 , the method flow includes:

[0099] 101: Before the calling terminal and the called terminal establish a call session, establish a first multimedia session with the calling terminal;

[0100] 102: Receive the first play request sent by the call session control node;

[0101] 103: According to the first play request, play the multimedia information set by the called terminal to the calling terminal through the first multimedia session.

[0102] The embodiment of the present invention establishes the multimedia session with the multimedia server before the call session is established, so that the process of establishing the multimedia session is advanced, avoiding the delay in playing multimedia information caused by the time delay in the process of establishing the multimedia session, and improving the efficiency of acquiring multimedia information.

Embodiment 2

[0104] The embodiment of the present invention provides a method for playing multimedia information, see figure 2 , the method flow includes:

[0105] 201: Before establishing a call session, establish a multimedia session in the PS domain with the multimedia server;

[0106] 202: When the terminal initiates a call, establish a call session;

[0107] 203: Receive multimedia information sent by the multimedia server through the multimedia session.

[0108] The embodiment of the present invention establishes the multimedia session with the multimedia server before the call session is established, so that the process of establishing the multimedia session is advanced, avoiding the delay in playing multimedia information caused by the time delay in the process of establishing the multimedia session, and improving the efficiency of acquiring multimedia information.

Embodiment 3

[0110] The embodiment of the present invention provides a method for playing multimedia information, see image 3 .

[0111] It should be noted that in this method embodiment, multimedia information (color ring back tone information) is set for the user corresponding to the called terminal. When the calling terminal initiates a call, before waiting for the called terminal to answer the call, receive Multimedia information set. Wherein, the call session control node is a mobile switching center in the embodiment of the present invention.

[0112] The method flow includes:

[0113] 301: The calling terminal initiates a call establishment request to the mobile switching center, where the call establishment request carries the identifier of the called terminal.

[0114] Wherein, the call establishment request may be a SETUP message.

[0115] 302: The calling terminal establishes a PS domain multimedia session with the multimedia server.

[0116] Specifically, when the calling...

Abstract

The invention discloses a method and device for playing multimedia information, and belongs to the technical field of communication. The method comprises the steps that before a calling terminal and a called terminal set up a calling session, a first request for setting up the multimedia session of a packet switching domain is received, wherein the first request is sent by the calling terminal; a first multimedia session with the calling terminal is set up according to the first request; a first playing request sent by a calling session control node is received, and multimedia information set by the called terminal is played to the calling terminal through the first multimedia session according to the first playing request. Due to the fact that the multimedia session is set up with a multimedia server before the calling session is set up, the process of setting up the multimedia session is brought forward, the situation that playing of the multimedia information is delayed due to time delay in the process of setting up the multimedia session is avoided, and the efficiency of obtaining the multimedia information is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for playing multimedia information. Background technique [0002] The ringback tone refers to the audio played to the calling terminal when the calling terminal initiates a call to the called terminal and before the called terminal picks up the phone to answer. With the development of communication technology, ring back tone appears again by playing video, picture, text and other multimedia information (that is, CRBT information and CRBT information). After the calling user and the called user set the multimedia information, respectively It is sent to the called terminal and the calling terminal, so that both terminals are closed before answering the call. [0003] The method of playing multimedia information in the prior art is: after the call session between the calling terminal and the called terminal is established, then respectively establish the ...
