Embodiment Construction

[0020] FIG. 1 is a flow chart of a method for implementing a CRBT restriction service in an IMS domain.

[0021] 101 Start a call process

[0022] 102 The CSCF at the calling side judges whether the calling user subscribes to the CRBT restricted service according to the initial filtering criteria. The objects of the initial filtering criteria (that is, which users customize the CRBT restricted service) can be one or more users according to the user's needs. You can choose SMS customization / Web customization / special service number customization / manual customization and other methods to meet the needs of users as conveniently as possible;

[0023] 103 If the calling user does not customize the CRBT restriction service, execute the normal call process;

[0024] 104 If the calling user has customized the CRBT restriction service, the CSCF at the calling side carries the caller restriction CRBT flag in the Invite message sent to the CSCF at the called side;

Abstract

The method includes steps: user subscribes service of restricting color ring; when user calls the called user, CSCF at calling side determines whether calling user subscribes service of restricting color ring based on initial filtering rules; if yes, then CSCF at calling side modifies Invite message to make it carry tag of restricting service of color ring; CSCF at calling side forwards modified Invite message to CSCF at called side; after receiving Invite message, CSCF at called side carries out parsing to find out that calling user subscribes service of restricting color ring so that no matter whether the called user subscribes service of color ring or not, service of color ring is not triggered; called side executes normal call flow, and plays back ordinary ring back tone to calling user. The invention makes calling user possible to restrict characteristic ring back tone of the called user. Through short message/Web ways, user can subscribe service of restricting color ring.

Description

technical field [0001] The invention relates to a method for restricting the color ring service at the calling side in the IMS domain. Background technique [0002] The color ring tone, that is, the personalized ring back tone service enables the calling user to hear personalized ringtones instead of the original monotonous beeping sound when dialing someone else's phone. [0003] In the current GSM, CDMA and even fixed telephone networks, the development of the personalized ring back tone service has been in full swing and achieved great success. When another user (calling user) calls the user number (called user) registered in the personalized ring back tone, before it is connected and off-hook, a piece of music, advertisement or the called user will be played to the calling user Set the message, at this time the calling user hears the personalized ring back tone set in the system by the service user. This method has been gradually accepted and widely used by people. [...
