Embodiment Construction

[0027] In order to achieve the purpose of the present invention, the embodiment of the present invention provides a short number calling method, system and query device solution between terminals, the fusion between the VPMN service based on the CS domain network and the Centrex service based on the IMS domain network In the scenario, the service data of each terminal in the virtual network is saved in the query device, so that when the terminals belonging to the VPMN service and the Centrex service make a short number call, the calling side can query the called terminal's long number from the query device. At the same time, the called side can also query the short number of the calling terminal, the group number of the calling terminal, and the group number of the called terminal from the query device. Terminals under the business and Centrex services can make short number calls.

[0028] The long number involved in each embodiment of the present invention refers to an ID num...

Abstract

The invention discloses a method, a system and a query device of short number call between terminals. Main contents include saving business data of all terminals in the query device under the integration scene between virtual private mobile network (VPMN) business based on CS domain network and Centrex business based on IMS domain network, so that a calling side can query a called terminal long number when a terminal conducts short number calling under the VPMN business and the Centrex business. Meanwhile, after a called side also can query a calling terminal short number, a calling terminal group number and a called terminal group number from the query equipment, when the calling terminal group number and the called terminal group number are the same, according to the calling terminal short number, the terminal under the VPMN business and the Centrex business can conduct the short number calling under the condition that VPN is not additionally added.

Description

technical field [0001] The solution of the invention relates to the field of wireless communication, in particular to a method, a system and a query device for calling short numbers between terminals. Background technique [0002] Virtual private mobile network (Virtual Private Mobile Network, VPMN) is based on circuit switching domain (Circuit Switching, CS), based on Global System for Mobile Communications (GSM) network, based on mobile intelligent network (Intelligent Network , IN) as a support, a logical voice channel dedicated network is established, and mobile terminals in the same VPMN group can realize mutual dialing of short numbers and enjoy preferential tariffs. [0003] The Virtual Switchboard (Centralized Exchange, Centrex) service is based on the Internet Protocol Multimedia Subsystem (IMS) service, and the Centrex service forms a virtual communication group for connected terminals in a wireless or wired manner, so that The terminals in this virtual group can ...
