Problems solved by technology

[0016] In the prior art, the number assigned by the UC system to each UC terminal has no registration status in the IMS network, and the service integration of the UC terminal and the mobile phone number can only be realized in the UC system, but not on the operator side. As a peer-to-peer trusted domain, the UC system does not check the calling and called numbers, so there is a possibility of stolen calls

Embodiment Construction

[0039] Aiming at the above-mentioned problems existing in the prior art, the embodiment of the present invention provides a technical solution for realizing intercommunication between an enterprise UC system and an IMS network. In this technical solution, a gateway is deployed between the enterprise UC system and the IMS network, and the number assigned by the enterprise UC system to the UC terminal and the DID (Direct Inward Dialing) assigned by the operator to the UC terminal are configured in the gateway. ) number mapping relationship; when the gateway receives the UC terminal online message reported by the UC server, the gateway can determine the corresponding DID according to the number assigned to the UC terminal by the UC system carried in the message and the mapping relationship stored by itself number, and register the DID number with the IMS network; when the gateway receives the call request message initiated by the UC terminal to call the operator user, the gateway ...

Abstract

An embodiment of the invention discloses a method and equipment for realizing intercommunication of an enterprise US system and an IMS network. The method includes: a gateway receives a message that a UC terminal is on line which is reported by a UC server, determines that the enterprise UC system carried in the message is a DID number corresponding to a number allocated to the UC terminal, and registers the DID number in the IMS network; and when the gateway receives a call request message of calling operator users which is initiated by the UC terminal, the gateway determines a DID number that a calling number carried in the call request message, the calling number is replaced with the DID number, and a call flow is initiated to the IMS network. In the method, business control of the UC terminal by an operator side is realized, and risks of theft-dialing are reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for realizing intercommunication between an enterprise UC system and an IMS network. Background technique [0002] Based on the IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) international standard of 3GPP (the 3rd Generation Partnership Project), China Mobile innovatively proposed CM-IMS (China Mobile-IMS, China Mobile IMS). CM-IMS is China Mobile's end-to-end system-level solution for full-service operations, involving core network, access equipment, services, terminals, bearer and support systems. [0003] The unified Centrex (virtual switchboard) service based on CM-IMS provides enterprise customers with business functions such as group multimedia phone, fixed and mobile converged V-network, fixed and mobile converged one number, and enterprise converged switchboard, realizing fixed and mobile convergence. [0004] Enterprise UC...
