Problems solved by technology

[0007] CNIR is undoubtedly helpful for calling users who need to hide their identities, but CNIR also makes it impossible for called users to know who the CNIR user who initiated the call is.
Since communication is two-way in most cases, even CNIR users, when acting as the called party, the called terminal they use cannot display the number of the calling CNIR user
[0008] Therefore, providing users with value-added services that suppress CNIR can also bring considerable income to operators. There is no available CNIR suppression scheme in the existing IMS specifications

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] figure 1 It is a schematic structural diagram of a communication network supporting caller rejection suppression according to a specific embodiment of the present invention. It includes a call control device 1, a network server 2, and two user terminals (including a calling terminal A and a called terminal B).

[0025] The positional relationship between the call control device 1 and the network server 2 includes:

[0026] Scenario 1: The call control device 1 and the network server 2 are physically integrated, and the network server 2 is a device in the call control device 1;

[0027] Situation 2: The call control device 1 and the network server 2 exist as two physical entities independently of each other.

[0028] figure 2 It is a flowchart of a method for suppressing caller rejection in a call control device of a communication network according to a sp...

Abstract

The invention provides a device and method for suppressing caller rejection in a communication network. Specifically, before the call establishment request message reaches the proxy control device, the present invention modifies the caller rejection indication information in the call establishment request message to indicate that the calling party number is allowed to be displayed. By adopting the technical solution provided by the invention, the suppression of caller rejection can be realized in network environments such as IMS.

Description

technical field [0001] The invention relates to a communication network, in particular to the suppression of caller rejection in the communication network. Background technique [0002] In IMS (IP Multimedia Subsystem), operators provide a value-added service called Caller Rejection (CNIR) for users with special needs. For ease of understanding, assuming that the user terminal is a mobile phone, the CNIR service will correspond to a logical number owned by the user after activation. When the user uses the logical number (insert the SIM card corresponding to the logical number into the mobile phone) When initiating a call to another user, the system will recognize that the call establishment request message of the calling user is the calling user who refuses to display, and hide its real identity (for example, logical number) for it, and the terminal device of the called user cannot display it. The number of the calling party, that is, the caller rejection has been realized....
