Problems solved by technology

[0015] The main disadvantage of the existing technical solution is that it needs to increase the investment in building the intelligent network. Relatively speaking, the investment in the intelligent network is still relatively large.
The increase in investment results in an increase in costs and difficulty in quickly promoting the business
Although the intelligent network can provide rich and flexible services, in some areas that want to develop mobile services in a small area or only hope to provide some services including VPN, it is not desirable to realize this service through the intelligent network

Embodiment Construction

[0029] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0030] The principle of this scheme is to add some information in the user's home HLR, and store the correspondence table of short numbers and long numbers of different user groups. In the correspondence table, a group ID is set for each group, and different groups use Indicates the group ID.

[0031] HLR only needs to store the information of the groups that the users of this HLR belong to. For the groups that do not have users belonging to this HLR, HLR does not need to store their information. These information have no practical significance for the realization of the inventive solution. Whether it is necessary to store the group ID of the related group depends on the needs of the system.

[0032] Because the user initiates the service at the end office, the end office needs to be able to change the short number to a long number. The ...

Abstract

The present invention relates to method of realizing VPN service of mobile user without increasing intelligent network equipment on the basis of available mobile network. The short and long number corresponding method in VPN service features that in the HLR of the mobile user, one conversion list between the long numbers and short numbers of the user group is increased and stored. When the mobile user initiates VPN service request, MSC or VLR is made to perform information interaction with the HLR of the caller to complete the connection between the caller and the callee. The advantages of the present scheme includes less investment, no increase in the investment for intelligent network, relatively low cost and fast service development.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for realizing mobile user VPN service on the basis of the existing mobile network without adding intelligent network equipment. technical background [0002] In the mobile network, the VPN service is a very important service. It is a business that establishes a logical telephone network on the mobile communication network, and enables enterprises and group user groups to communicate with each other through abbreviated dialing and special numbering plans. This service is similar to the small exchange used by enterprises in the fixed network at present. It can provide good services for groups, enterprises and institutions, and extend enterprise telecommunications services to mobile networks. [0003] At present, my country's mobile network mainly has two standards. One is the GSM standard widely used in Europe. China Mobile and China Unicom both have networks of this s...
