A method and device for establishing a private network connection

Abstract

The present invention relates to the communication field, and in particular to a method and device for establishing a private network connection, which are used to solve the problem that a private network mobile terminal communicates through a private network. The method is as follows: SBC1 sends a call request from UE1 to UE2, And send the resource reservation request sent by UE2 to UE1 through PGW1, and then send the resource modification request sent by PGW1 to UE2, and send the resource modification response message returned by UE2 to UE1, triggering UE1 and UE2 to complete the establishment of wireless resources In this way, after completing the connection establishment process, the private network mobile terminal can access the private network for communication, meeting the growing demand for high-speed data network and high-definition voice calls of private network mobile terminals, and improving user experience. In addition, it effectively improves the utilization rate of network resources, improves the security of private network mobile terminals accessing the private network, and improves the flexibility of business management.

Description

technical field [0001] The invention relates to the communication field, in particular to a connection establishment method and device for a dedicated network. Background technique [0002] With the rapid development of mobile networks, it has now entered the fourth generation mobile communication system (Fourth Generation, 4G) network era. Compared with the second generation mobile communication system (Second Generation, 2G) and the third generation mobile communication system (Third Generation Generation, 3G) network has been greatly improved, and has basically achieved full coverage of mobile networks. A private network refers to a network structure in which the network infrastructure and information resources in the network belong to a single organization, and the organization manages the network. [0003] In the prior art, private network communication is mainly realized through the 2G network Global System for Mobile Communication (GSM). Specifically, the mobile netw...

[0004] However, the prior art only deals with the security issues of mobile terminals accessing private networks, ensuring the secure access of private network communication data, and cannot provide mobile terminals with high-speed data network services such as voice and telephone. Terminals access private networks, and some private networks have established independent mobile networks for communication between mobile terminals, increasing the burden on existing mobile networks, reducing the utilization of network resources, increasing infrastructure costs, and greatly increasing Reduced the input cost of network equipment such as base stations
