Embodiment Construction

[0030] The present invention provides a method for realizing a virtual private network between multiple control nodes in a mobile communication system, and the present invention provides the possibility of realizing a nationwide VPN on the existing mobile communication network that is operated, calculated and managed with each province as a unit. Therefore, the mobile communication network can provide better services for group users with less investment.

[0031] Utilize the present invention to realize the business networking structure of nationwide VPN such as image 3 As shown, the present invention uses the Execute (execute) operation of INAP (Intelligent Network Access Protocol) on the basis of the original protocol, that is, on the cc7 NetWork (No. 7 signaling network) between SCP1 and SCP2. Through the Execute operation, users on each SCP in the virtual private network can query the user data on other SCPs, that is, query the number segment allocation information about ...

Abstract

The method of realizing virtual special network among several business control nodes includes determining the section distributing information including the service control node marking information and the corresponding section range for the service control nodes in the virtual special network to be formed, and maintaining the section distributing information in the service control nodes; and then the user of the virtual special network can complete the communication service via the service control nodes inside the virtual special network. The present invention solves the problem of establishing countrywide virtual special network.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing a VPN (virtual private network) among multiple service control nodes in a mobile communication system. Background technique [0002] At present, mobile virtual private network is a new service provided by mobile communication network operators for group users. Various services are carried out in the network, which provides great convenience for the group users to use and manage the mobile communication network. The typical intelligent network architecture in the existing mobile communication system can be divided into the structure of the nationwide virtual private network and the structure of the provincial virtual private network, such as figure 1 , figure 2 shown. And at present, by providing mobile virtual private network services on the wireless intelligent network, the problem of providing mobile virtual private network within the scope of a...
