Abstract: A session management method by a terminal in which a network initiates a session deactivation procedure to deactivate one or more sessions of a terminal. After the terminal in an inactive mode establishes an RRC connection to a new second base station, the second base station indicates, through RRC connection reconfiguration, the terminal to delete related information of the to-be-deactivated session, or the second base station uses an RRC connection resume response message to carry an identifier of the one or more to-be-deactivated sessions, and the terminal deletes session-related information corresponding to the identifier of the one or more to-be-deactivated sessions. In this way, the terminal is enabled to process the related information of the to-be-deactivated session in a timely manner.

Abstract: A communication method that includes: a terminal transmits data for a first application in a first communications system via a first protocol data unit (PDU) session, where the first PDU session does not support interworking between the first communications system and a second communications system. The terminal moves from the first communications system to the second communications system. After the terminal moves from the second communications system back to the first communications system, the terminal obtains a second PDU session based on at least first transmission information of the first application, and transmits data for the first application in the first communications system via the second PDU session, where the first transmission information includes an identifier of the first application.

Abstract: An RRC connection release control method and an apparatus are applied to the field of mobile communication technologies and relate to the field of artificial intelligence (AI) and machine learning algorithms. When a first application of a terminal runs in a foreground, a timing duration of a first timer is set based on a timing duration corresponding to the first application, where the first timer starts when the terminal is in an RRC connected state, and when the terminal exchanges information with a network device, the first timer is reset, so as to control release of an RRC connection of the terminal based on the first timer.

Abstract: This application discloses a communication method. When determining that a network used to provide a service does not meet a transmission requirement of service data, a terminal device requests, from a PCF, an SMF, or an NWADF, to analyze a reason why the network does not meet the transmission requirement of the service data. The PCF, the SMF, or the NWADF obtains information used to recover a service, and sends the information to a device that performs a service recovery operation, for example, the terminal device or an access network device. The information used to recover the service is used to enable the network to meet the transmission requirement of the service data.
