Embodiment 1

[0037] based on image 3 In the shown network structure, using the above mobile terminal and system, the flow chart of the mobile terminal dialing the short number in the group of the IMS terminal to initiate the call in the unified Centrex service is as follows Figure 4 shown, including:

[0038] Step S401, the user inputs the called number through the mobile terminal 301 and initiates a call, the mobile terminal 301 obtains the called number input by the user, and judges that the acquired called number is a short number of the unified Centrex service, and then according to the locally stored The corresponding relationship between the long number and the short number determines the called long number corresponding to the called number; wherein, the corresponding relationship between the long number and the short number includes the long number of each user in the unified Centrex service group to which the mobile terminal 301 belongs The corresponding relationship with the s...

Embodiment 2

[0046] based on image 3 In the shown network structure, using the above-mentioned mobile terminal and system, the flow chart of the unified Centrex service in which the IMS terminal dials the short number within the group of the mobile terminal to initiate a call is as follows Figure 5 shown, including:

[0047] Step S501, the user enters the called number through the IMS terminal 308 to initiate a call, and the IMS terminal 308 sends an Invite message to the S-CSCF 305, wherein the P_Asserted_Identity header field and the From header field are the calling long number, and the RequestURI header field is the called short number .

[0048] Step S502 , the S-CSCF determines that the IMS terminal 308 has subscribed to the unified Centrex service according to the iFC rule obtained from the calling HSS 306 , triggers the service, and sends an Invite message to the Centrex AS 307 .

[0049] Step S503, Centrex AS 307 obtains the called short number from the received Invite message...

Abstract

The invention discloses a number processing method, device and system for a unified Centrex service, comprising: a mobile terminal acquires an input number; Corresponding relationship, determine the short number or long number corresponding to the number. By adopting the method, device and system provided by the present invention, when realizing the unified Centrex service, the processing flow of signaling on the network side is reduced, and the complexity of the networking mode is reduced.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a number processing method, device and system for a unified virtual switchboard Centrex service. Background technique [0002] The virtual private branch exchange service is to establish a platform on the public network to provide a private network service of a virtual private branch exchange PBX (Private Branch Exchange). Services such as outgoing calls outside the group, incoming calls outside the group, call forwarding, call waiting, and call hold. Among them, the intra-group call provides a way for members in the same group to communicate with each other in the form of short numbers. [0003] At present, VPMN (Virtual Private Mobile Network, Virtual Private Mobile Network) is the embodiment of such services on PLMN (Public Land Mobile-communication Network, Public Land Mobile-communication Network). [0004] The unified Centrex service is the realization of such serv...
