Information transmission method and system and color ring server and terminal

Abstract

The invention discloses an information transmission method and system, a color ring back tone server and a terminal. The method includes: after the voice path between the CRBT server and the terminal is established, the CRBT server finds personalized user information according to the customized information, and if it contains non-ring tone information and ring tone information, then modulates the non-ring tone information into voice information and ring tone information. The voice information is packaged and sent to the terminal; the terminal receives the packaged information and demodulates the modulated voice information into original state information. The system includes: a voice channel system, used to establish a voice channel between the color ring back tone server and the terminal; the color ring back tone server, used to modulate non-ring tone information into voice information and ring tone information, package them, and send them to the terminal; the terminal is used to receive The packaged information sent by the CRBT server demodulates the modulated voice information into original state information. The present invention can utilize the existing network to realize simultaneous transmission of personalized user information including ring tones and non-ring tones.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an information transmission method and system in communication network value-added services, a color ring back tone server and a terminal. Background technique [0002] At present, with the continuous development of telecommunication technology, people's requirements for telecommunication services are also increasing day by day, resulting in the emergence of many personalized telecommunication services, and the ring back tone service is one of them. The ring back tone service is a service that allows the telephone user to customize the ring back tone. When the calling user dials the called user, the calling user will hear the personalized tone customized by the called user after the called terminal rings and before picking up the phone. ring back tone. This service enables users to display personalized information, so it has achieved good market effects. [0003] ...

AI Technical Summary

Problems solved by technology

[0009] The process of the other two schemes for implementing CRBT is roughly similar to that of the intelligent network scheme, but there is a limitation in these schemes, that is, the current scheme only supports playback of audio data, that is to say, only ring tones can be played, and non-ring tones cannot be included. The playback of personalized information, such as richer pictures and text, cannot meet the growing personalized needs of users.
