Problems solved by technology

[0003] However, different from audio ring tones, multimedia ring tones containing video and pictures have a relatively high bit rate, and compressed images or videos are highly sensitive to bit errors, so due to bandwidth problems, bit error retransmission delays, etc. The receiving delay is also relatively high
This limits the wide application of multimedia ring back tones containing video and pictures to some extent

Embodiment Construction

[0010] In the present invention, the multimedia CRBT system includes functional entities such as an application server (AS), a media server (MS), a calling party and a called party. The total length of the multimedia ring back tone file data is L bytes, including the starting end data [0, Pn-1] of the multimedia ring back tone of n bytes and the data [Pn, L] part starting from the splicing point of L-n bytes, and Pn is defined as stitching point.

[0011] Referring to shown in Fig. 1, its control process of multimedia color ring back tone pre-stored receiving method of the present invention is:

[0012] First, the media server sends to the calling party the initial data [0, Pn-1] of the multimedia ring back tone set by the called party. The specific method of implementation can be regularly pushed in push mode or obtained by the calling party in pull mode. After the calling party receives the start-end data [0, Pn-1] of the multimedia CRBT sent by the media server, it is stor...

Abstract

The invention relates to the digital mobile communication field, particularly discloses a method for realizing multimedia color ring prestoring reception in a mobile communication system. The method comprises that, a multimedia color ring with a length of L bytes is divided into two portions, [0, Pn-1] and [Pn, L], a media server sends start end data [0, Pn-1] of the multimedia color ring set by a called part to a calling part, and the calling part receives the start end data [0, Pn-1] of the multimedia color ring sent from the media server and then stores the data. After starting a color ring service process, a calling user terminal receives multimedia color ring data [Pn, L] started from a jointing point Pn from the media server, and continuously plays the media color ring while jointing the start end data [0, Pn-1] of the prestored media color ring in network buffering. The invention is capable of effectively reducing playing relay of the multimedia color ring.

Description

technical field [0001] The invention relates to the field of digital mobile communication, in particular to a method for realizing pre-storage and receiving of multimedia ring tone in a mobile communication system. Background technique [0002] The multimedia ring back tone service is a value-added service of the wireless network. It can be very personalized videos, pictures, text and music, among which videos are more entertaining and expressive. Multimedia CRBT users can set different videos for a certain caller or a certain group of callers. When a caller calls, the system plays different videos according to the status of the called user and the group to which the caller belongs. If the called party is busy or cannot be connected, the default system video that can express the called party's current status will be played; if the called party is idle, the video customized for the group will be played according to the group to which the calling number belongs. In either ca...
