Abstract: The present invention provides a cell selection method and apparatus. The cell selection method includes: sending, by a non-access stratum of user equipment UE, network list information to an access stratum of the UE, where the network list information includes a list of forbidden networks and a list of forbidden networks for a GPRS service; determining, by the non-access stratum, indication information about a cell selection priority according to an operation mode of the UE; and sending, by the non-access stratum, the indication information to the access stratum, so that the access stratum selects a suitable cell according to the network list information and the indication information. The present invention can effectively prevent the UE from entering a state of being able to normally camp but unable to obtain a normal service, thereby improving user experience.

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 method and an apparatus for switching an RRC state includes: sending, by a communications apparatus, indication information to a network device, where the indication information is used to indicate that the communications apparatus requests to enter an RRC inactive state; after completing a registration process of an RRC connected state, receiving, by the communications apparatus, an RRC connection release message that is sent by the network device based on the indication information, where the RRC connection release message is used to indicate the communications apparatus to enter the RRC inactive state; and entering, by the communications apparatus, the RRC inactive state from the RRC connected state based on the RRC connection release message.

Abstract: Example embodiments of the present disclosure provide a method and a communications apparatus for switching an RRC state. The method includes: sending, by a communications apparatus, indication information to a network device, where the indication information is used to indicate that the communications apparatus requests to enter an RRC inactive state; after completing a registration process of an RRC connected state, receiving, by the communications apparatus, an RRC connection release message that is sent by the network device based on the indication information, where the RRC connection release message is used to indicate the communications apparatus to enter the RRC inactive state; and entering, by the communications apparatus, the RRC inactive state from the RRC connected state based on the received RRC connection release message. In this way, energy consumption of the terminal-side communications apparatus can be effectively reduced, and network resource consumption can also be reduced.

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.
