Abstract: In a communication method, a session management function network element initiates a procedure of a first operation for a first session; the session management function network element receives a request to establish user-plane resources for the first session from an access and mobility management function network element in a process of performing the first operation; and the session management function network element determines a subsequent procedure based on the first operation.

Abstract: A communication method and apparatus are provided, to resolve a problem that a terminal device cannot perform normal communication on other accesses due to an operation performed on common parameters over some accesses of the terminal device. The method includes: When the terminal device on a first access is switched from a first PLMN to a second PLMN, if a state of the terminal device on a second access is that the terminal device is registering with the first PLMN or has registered with the first PLMN, the terminal device determines not to delete a first mobility management parameter on the first access. If a state of the terminal device on a second access is that the terminal device has not registered with the first PLMN, the terminal device determines to delete a first mobility management parameter on the first access.

Abstract: A handover handling method and apparatus applied to a scenario in which user equipment (UE) is handed over from a first access and management function (AMF) to a second AMF, and where the method includes receiving, by the UE, a handover command message from a first access network device, wherein the handover command message carries a Non-Access Stratum container (NASC), performing, by the UE, integrity verification on the NASC, and continuing, by the UE, to use a first NAS security context when the integrity verification performed on the NASC fails, wherein the first NAS security context is a security context used between the UE and the first AMF.

Abstract: This application discloses a communication method and apparatus. The method includes: A UE sends a registration request message to an AMF, where the registration request message includes indication information, and the indication information indicates whether a disaster scenario exists. The AMF receives the registration request message, and sends a registration response message to the UE based on the indication information and a load status. The UE receives the registration response message.

Abstract: A communication method and a communications apparatus, where the method may include: selecting or re-selecting, by a terminal device, from a first cell to a second cell through cell selection or re-selection, where radio access technologies of the first cell and the second cell are different, and where the terminal device is in an inactive mode in the first cell; re-selecting, by the terminal device, to the second cell through cell re-selection; and initiating, by the terminal device, a registration procedure after completing the cell re-selection. When the terminal device in inactive mode performs cell re-selection based on different radio technologies, the terminal device initiates the registration procedure or a service request procedure, for NAS signaling connection recovery. When the terminal device changes a radio access technology, a network device can update information.

Abstract: A session processing method in wireless communications and a terminal device include sending, by the terminal device, a session establishment request to a core network device, where the session establishment request requests to establish a session, and the session is supported by a network slice corresponding to the session, determining, by the terminal device, that establishment of the session fails, determining, by the terminal device, a forbidden time period corresponding to the session, and forbidding, by the terminal device, the terminal device from sending the session establishment request within the forbidden time period.
