Detailed Description

In the embodiment of the present invention, the LAN service (also referred to as a LAN type service) may refer to a private communication service provided on a communication network such as 3GPP (3rd Generation Partnership Project). The 5G LAN type service is a private communication service provided over a 5G communication network. The private communication service may be an IP (Internet Protocol) based type or a non-IP type private communication service. non-IP type communications such as ethernet. LAN services may be deployed over private communication networks as well as public communication networks.

In one embodiment of the invention, the LAN may be referred to as a LAN group (e.g., a 5G LAN group) and is made up of a set of devices. The devices may be referred to as members of the LAN. A LAN may be deployed on a local network (e.g., a local area network) or may be a local network formed from a set of devices. Devices in the LAN may include at least one of: terminal, server, bridge, switch. The devices of the LAN may be in wired or wireless connection. The devices in the LAN can access the LAN directly through the mobile communication network, or can access the LAN after accessing the mobile communication network through a relay (e.g., a terminal in the mobile communication network).

In another embodiment of the present invention, the LAN may also be referred to as a local network (e.g., a local area network). A LAN may provide private communication services for a group of devices, such as terminals. LANs may be deployed based on at least one of: port, IP subnet, VLAN (Virtual Local Area Network) and MAC (media Access Control) address. VLAN is a technique for logically dividing a physical local network into a plurality of broadcast domains. By setting the VLAN, the sending range of the data can be isolated, and the safety of communication in the VLAN can be improved.

A terminal supporting LAN services may access one or more LANs. A terminal supporting LAN-type services may leave an already-accessed LAN. Typically, a LAN only allows member devices access. Temporary access to non-member devices may also be supported for some open LANs.

In this embodiment of the present invention, a Private Virtual Network (PVN) may be a Private Virtual Network supporting LAN type services. The concepts of PVN and LAN may be mixed and may generally refer to a network or a group of devices supporting private communication services.

In order to support LAN services, the following problems need to be solved:

problem 1: a terminal may have simultaneous access to both LAN and non-LAN requirements. The UPF may also support both connections to LANs and connections to non-LANs, such as public networks (referred to as public networks for short). When a terminal accesses a LAN and a non-LAN through a UPF, communication addresses (such as IP addresses, which are described later as IP addresses) mapped by the UPF are different. For example, when accessing a LAN, the UPF maps an IP address in the LAN; when accessing the public network, the UPF maps the IP of the public network.

When the LAN connection and the non-LAN connection of the terminal are established on the same UPF, the UPF will not know whether the IP address in the mapping LAN is sent to the LAN or the IP address in the mapping public network is sent to the public network for the data packet from the terminal.

Problem 2: a terminal may have simultaneous needs to access multiple LANs and the UPF may also support simultaneous connections to multiple LANs. The communication addresses (such as IP addresses, which are subsequently illustrated as IP addresses) of the UPF map are different when connected to different LANs. For example, when LAN-A is connected, UPF maps an IP address in LAN-A; when connected to LAN-B, the UPF maps the IP of a LAN-B network.

When a plurality of LAN connections of a LAN of a terminal are established on the same UPF, it is unclear to which IP address within the LAN the UPF maps for packets from the terminal.

Problem 3: it is not clear how the routing of the LAN, and the privacy of the LAN, are achieved.

A UPF (User Plane Function) may not serve just one LAN. The UPF can connect multiple LANs simultaneously. When the UPF lacks intra-LAN device information, it may send a broadcast or multicast packet to all terminals connected to it when it receives the packet. Thus, the terminal not in the LAN will receive the data packet of LAN, which can not meet the privacy requirement of LAN communication, and the LAN communication is not safe; on the other hand, it will cause waste of air interface radio resources. In addition, when a terminal outside one LAN transmits data to one LAN, the UPF cannot recognize it. The security and reliability of LAN communication are also unsatisfactory.

Problem 4: how to select the UPF is not clear.

A gateway in a mobile communication network (e.g., UPF, which is described as an example of a gateway in a mobile communication network) may or may not support LAN services.

One or more LANs (e.g., LAN _1, LAN _2) may have been deployed on the UPF. When the terminal wants to access LAN _1, it is not clear how to confirm which UPF is the one of LAN _ 1.
