Problems solved by technology

[0004] Terminal device A and terminal device B belonging to the same 5GLAN group may communicate across regions or across operator networks. The UPFs connected to the terminal devices for cross-regional communication are different, and they belong to different operators. How to realize the transmission of data packets between terminal equipment A and terminal equipment B belonging to the same 5GLAN group in the 5G network without the deployment and participation of external application servers is an urgent problem to be solved

Embodiment approach

[0137] Mode 1: The first UPF forwards the packet to the second UPF through the forwarding tunnel identified by the forwarding tunnel identifier of the second UPF.

[0138] Mode 2: The first UPF forwards the packet to the second UPF indicated by the address of the second UPF.

[0139] Mode 3: The first UPF encapsulates the packet into an IP packet and sends it to the external network, and the external network routes the IP packet to the second UPF indicated by the IP address of the second UPF. Wherein, the destination address of the IP packet is the IP address of the second UPF.

[0140] S108. The GMF sends a second notification message to the second SMF, where the second notification message includes the identifier of the first UPF and the address of the first terminal device.

[0141] Specifically, after receiving the second notification message, the second SMF performs a process similar to that performed by the first SMF, specifically as follows:

[0142] S109. The second ...

Abstract

The invention provides a message transmission method and device. The method comprises the steps that a group management network element receives a first message sent by a first session management network element, wherein the first message comprises an address of first terminal equipment and an identifier of a first user plane network element for providing LAN service for the first terminal equipment; the group management network element receives a second message sent by a second session management network element, wherein the second message comprises an address of second terminal equipment andan identifier of a second user plane network element for providing LAN service for the second terminal equipment; the group management network element determines that the first terminal device and the second terminal device belong to the same local area network group; the group management network element sends a first notification message to the first session management network element, wherein the first notification message comprises the identifier of the second user plane network element and the address of the second terminal device; and the group management network element sends a second notification message to the second session management network element, wherein the second notification message comprises the identifier of the first user plane network element and the address of the first terminal device.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a message transmission method and device. Background technique [0002] With the development of mobile communication systems, the 3rd Generation Partnership Project (3GPP) standard has officially established a project for the 5th Generation mobile communication technology (5G) local area network (LAN) requirements. The project clarifies that 5G networks need to support virtual LAN services, that is, 5G networks need to provide multiple types of transmission services for terminal devices belonging to the same 5GLAN group to ensure mutual communication between terminal devices in the same 5GLAN group. [0003] Determined by the characteristics of the LAN service itself, the LAN service is completed by the 3GPP network for mutual communication between terminal devices, without the deployment and participation of external application servers, such as file shari...
