Communication method, user plane gateway and communication system

Abstract

The invention provides a communication method, a user plane gateway and a communication system. Relates to the technical field of communication. The method comprises the following steps: receiving a second session request which is sent by a session management network element and comprises a first IP address; the first IP address is used for indicating an IP address allocated by the first UPF network element to the terminal equipment in a private network; in response to the second session request, generating a second session response message; the second session response message comprises a second IP address, and the second IP address indicates a public network IP address; sending a second session response message to the session management network element, so that the session management network element generates a third session request based on the second IP address and sends the third session request to the second UPF network element; the second UPF network element is a network element in a public network. According to the invention, the problems of potential safety hazard of network data of a public network and a private network, invalid resource consumption and IP address conflict between the public network and the private network in the prior art can be solved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a communication method, a user plane gateway, a communication system, a computer-readable medium, and a network device. Background technique [0002] In the fifth generation (5th-generation, 5G) mobile communication system, a large number of enterprise users expect to use fast and reliable 3rd generation partner ship project (3GPP) technology to achieve the coverage of enterprise parks. However, for enterprise private network users, there is still a demand for accessing a private network data network (data network, DN) on the public network, and a demand for accessing the public network DN while accessing the private network. For example, a user remotely accesses business data on the enterprise private network through an enterprise terminal. [0003] In the existing 5G system, in the above-mentioned private network scenario where only user plane network el...
