Abstract: The present disclosure relates to communications methods and apparatus. In one example method, a terminal device generates a first message. The first message is used to request to establish a protocol data unit (PDU) session home-routed to a first network. The terminal device sends the first message to a first access and mobility management function (AMF) entity. The first AMF entity is a network element in a second network.

Abstract: A method applied to processing of access stratum (AS) security for terminal handover from a source cell to a target cell, including obtaining a derivation parameter, deriving a target AS root key based on a source AS root key and derivation parameter, and calculating, based on the target AS root key, an AS security key used in the target cell. The source AS root key is an AS root key used in the source cell, the target AS root key is an AS root key used in the target cell, the derivation parameter is used to derive an AS root key and corresponds to a RAN node or a RAN node group or an area in which the target cell is located, and cells at a same RAN node, RAN node group, or area have a same derivation parameter.

Abstract: This application discloses a method applied to a scenario in which a terminal device moves from a first AN node to a second AN node. The method includes: receiving identification information of a to-be-activated session from the terminal device via the second AN node; sending a context release command to the first AN node when a signaling connection of the terminal device exits between an AMF node and the first AN node; receiving a context release complete message carrying identification information of an active session of the terminal device from the first AN node; when the to-be-activated session and the active session have a same session, sending a first request message to request to deactivate the same session to an SMF node corresponding to the same session; and after the same session is deactivated, sending, to the SMF node, a second request message to request to activate the same session.

Abstract: Embodiments of the present disclosure disclose a session activation method, device, and system, and relate to the field of the communications technologies, to resolve an existing problem of relatively high signaling overheads during PDU session activation. The method includes: receiving, by a control plane node, indication information from an AMF node, where the indication information is used to indicate that the AMF node receives a service request message sent by a terminal device; and sending, by the control plane node, an identifier of a to-be-activated PDU session of the terminal device to an SMF node or the AMF node based on the indication information. The embodiments of the present disclosure are used in a PDU session activation process.

Abstract: A data processing method includes receiving by an access network device a vehicle-to-everything (V2X) communication parameter of a group member device. The method also includes storing, by the access network device, the V2X communication parameter with context about a group to which the group member device belongs. The V2X communication parameter is used for allocation of a ProSe communication 5 (PC5) resource to the group member device.

Abstract: A communication method and apparatus are provided. A first terminal device sends a first vehicle to everything (V2X) service based on a first layer 2 address pair, and sends a second V2X service based on a second layer 2 address pair. Both a destination layer 2 address in the first layer 2 address pair and a destination layer 2 address in the second layer 2 address pair correspond to a terminal device group. A transmission configuration of the first V2X service is different from a transmission configuration of the second V2X service. Because the first terminal device allocates V2X services with different transmission configurations to different destination group L2 addresses, discontinuous reception (DRX) can be enabled for some V2X services, to effectively save power of the first terminal device, and DRX can be disabled for some V2X services, to meet a quality of service (QoS) requirement of V2X services.
