Method for realizing color ring back tone service on terminal

Abstract

This invention provides a method for realizing color ring-back service on a terminal relating to a service exchange point A, a standard protocol stack module B of the called terminal and a call control module C of the called terminal, in which, the terminal user assigns a color ring file for the C, when a calling calls the called terminal where B and C place, the call request will arrive at A, which will send the request to B, who gets the color ring sound to be played from C and sends the instruction for opening of the channel of color rings, A receives the instruction from B and determines that B has set up the color ring service and then opens the channel to set up a speech channel for the two party terminals and informs B, who informs C at once, C utilizes this channel to send the color ring sound to the calling party in the form of sending ordinary ring-back sound and the calling party hears the sound.

Description

Technical field [0001] The invention relates to a communication technology combining an intelligent network and NGN (Next Generation Networking, next generation network), in particular to a personalized ring back tone technology. Background technique [0002] With the continuous development of personalized ring back tones, color ring back tones (or called color ringtones, or CRBT for short) in the field of intelligent network communications, and the continuous expansion of user groups, CRBT services are in the midst of profit growth for communication operators. Plays an increasingly important role. [0003] The current CRBT service is mainly used in fixed-line and mobile communications. Ordinary landline or mobile phones, and PHS users can set their own CRBT through the voice hotline or operator’s website. When someone dials their landline or mobile phone, they hear It is not the boring ring back tone, but the music ring tone set by yourself. The main implementation process is: a...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: to overcome the problem in the prior art that operators need to invest in the configuration of the color ring center to open the color ring service for the end users in the IP domain in the NGN with softswitch as the switching center, and to solve the problem in the IP The terminal users in the domain cannot set the color ring back tone at will; and then provide a method for realizing the color ring back tone service on the terminal, and can open and set the color ring back tone at will for the terminal users in the IP domain without increasing investment by the operator Methods
