Abstract: A route configuration method includes determining, by a session management network element, that a first terminal in a first group is allowed to communicate with a second terminal in a second group. The route configuration method further includes sending, by the session management network element, first forwarding information to a first user plane network element. The first user plane network element is configured to provide a service for the first terminal. The first forwarding information is useable by the first user plane network element to forward a first packet. The first packet is to be sent by the first terminal to the second terminal.

Abstract: This application provides a communication method, apparatus, and system. In the method, a session management network element determines, in a process of creating a session for a terminal in a group, a transit device that provides a 5GVN service for the group, and send a first forwarding rule to the transit device. The transit device is configured to forward data between any two user plane network elements that provide the 5GVN service for the group. The first forwarding rule includes forwarding information of at least one user plane network element and forwarding information of at least one terminal served by the at least one user plane network element, and is used by the transit device to forward, to the user plane network element that serves a terminal, a data packet whose destination address is an address of the terminal.

Abstract: This application provides a communication method and an apparatus. The method includes: An access management network element receives a registration request from a terminal device, and the access management network element obtains configuration type indication information, determines, based on the configuration type indication information, to perform restricted registration, and starts a restricted registration timer. After the restricted registration timer expires, the access management network element initiates a deregistration procedure to deregister the UE from a network. By using the method, the terminal device can be prevented from maliciously camping or accessing another service for a long time. In addition, this solution is simple to implement, and easy to deploy and implement.

Abstract: Embodiments of this application provide a local area network communication method, a device, and a system. The method includes: A session management network element obtains, in a session management process, an address or a virtual local area network identifier VID information of user equipment UE corresponding to each 5G local area network 5GLAN service accessed by a session, and obtains service area information of each 5GLAN service from a local area network controller LAN Controller. The SMF subscribes to, from a mobility management network element, a mobility event that is based on each 5GLAN service, and obtains a mobility event report that is based on a service area of the SMF, and a corresponding 5GLAN identifier. The SMF updates a rule of a corresponding session in a user plane network element based on the mobility event report.

Abstract: Embodiments of a target edge application server (T-EAS) and a related method for supporting an application context relocation (ACR) procedure of user equipment (UE) in a communication network are disclosed. In response to a predicted movement of the UE from a current location to a predicted location within a coverage region of the T-EAS, the T-EAS is configured to receive, in an ACR execution phase of the ACR procedure, an application context of the UE from a source edge application server (S-EAS). Moreover, in response to obtaining information that the UE is no longer expected to move to the predicted location within the coverage region of the T-EAS, the T-EAS is further configured to perform, in a post-ACR clean-up phase of the ACR procedure, at least one post-ACR clean-up operation which at least includes discarding the application context.

Abstract: A method for instantiating an edge application server and an apparatus. A first network element receives first information from a second network element. The first information includes network information and application information. The network information indicates a first network, and the application information indicates a first application. The first information further includes information about a first event that is related to the first application and that is in the first network. The first event is that an edge application server corresponding to the first application is not found in the first network. The first network element determines, in response to the first event meeting a first condition, to instantiate a first edge application server corresponding to the first application in the first network.
