Embodiment Construction

[0044] Before introducing the embodiments of the present application, some terms involved in the embodiments of the present application are explained. It should be noted that the following explanations are for the purpose of making the embodiments of the present application easier to understand, and should not be regarded as limiting the scope of protection required by the embodiments of the present application.

[0045] In 5G LAN technology, by configuring different traffic forwarding methods for user plane function (UPF) entities in the 5G communication network, data packets in the same 5G VN group can be transmitted between PDU sessions established by different terminals. to retweet.

[0046] 5G LAN technology can have the following characteristics:

[0047] 1) Dynamic group management of terminals. The UDM entity can maintain all the subscription information of the terminals in the VN group, and industry customers can dynamically add or delete terminals from the VN group...

Abstract

The invention provides a communication method, device and system and a computer storage medium, and belongs to the technical field of communication. In the communication method, although a first UE and a second UE in the same VN group are located in different networks, a session establishment request sent by the first UE can be forwarded to a second network side by a first mobility management network element, so that a session of the first UE and a session of the second UE are respectively established in the first network and the second network; and a second mobility management network element can also send the VN tunnel information corresponding to the session of the second UE and the IP address of the second UE to the first network side, so that the user plane network element corresponding to the session of the first UE can forward the data packet to the user plane network element corresponding to the session of the second UE through the VN tunnel, and the first UE and the second UE can realize private network communication based on user plane network element forwarding.

Description

technical field [0001] The present application relates to the communication field, and in particular to a communication method, device, system and computer storage medium. Background technique [0002] The fifth generation mobile communication technology (5th generation mobile communication technology, 5G) is the latest generation of cellular mobile communication technology. 5G covers multiple scenarios such as residences, offices, enterprises and factories. [0003] Since these scenarios require the use of dedicated network services, a local area network (local area network, LAN) technology based on a 5G communication network is proposed, which may be called a 5G LAN. User equipment can be subscribed to a virtual network (virtual network, VN) group, and 5G LAN can provide dedicated network communication services for user equipment in the VN group. Among them, the user equipment in the VN group performs private network communication based on the 5G communication network. ...
