IMS (IP Multimedia Subsystem) communication method based on superposition of public network and private network

Abstract

The invention discloses an IMS (IP Multimedia Subsystem) communication method based on superposition of a public network and a private network, which is used for solving the technical problem that a public network user cannot directly access the private network. Specifically, according to the IMS communication scheme based on superposition of the public network and the private network, VXLAN devices are arranged on a public network side and a private network side respectively, and a UDP tunnel used for transmitting communication messages is established, so that an operator can switch and access a public network environment and a private network environment without manually switching an SIM (Subscriber Identity Module) card. And when communication message interaction is carried out in different network environments, through multiple times of matching verification and user information authentication, the network resource distribution pressure is reduced, and the network security is improved. And the communication message is encrypted by replacing a real IP for the communication message, so that the privacy of an operator is protected, and the network security is further improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an IMS communication method based on the superposition of a public network and a private network. Background technique [0002] With the continuous maturity of communication technology, some enterprises use advanced communication mechanisms to deploy special wireless networks to realize wireless communication functions within enterprises. Generally, we refer to public wireless communication networks operated by telecom operators as public networks, and wireless networks built by enterprises as private networks. [0003] In the process of realizing the prior art, the inventors found that: [0004] The essence of the private network is a small private network superimposed on the public network environment. Most of the private network environment is within the coverage of the public network environment. [0005] Considering the security performance of the priva...
