Abstract: A paging collision processing method and a related apparatus are provided. The method includes: upon detecting that a paging occasion in a first camped cell collides with a paging occasion in a second camped cell, a terminal device determines a first paging parameter, and sends a first paging parameter to a first network device corresponding to the first camped cell. The terminal device receives a second paging parameter from the first network device, determines a second paging occasion of a first identity module card in the first camped cell based on the received second paging parameter, and monitors a paging message in the first camped cell on the second paging occasion, which does not overlap a third paging occasion of a second identity module card in the second camped cell in terms of time, thereby avoiding a paging collision that occurs when the terminal device monitors the paging message.

Abstract: In a data transmission method, a terminal device determines a first message, where the first message indicates that the terminal device is to move from a first network to a second network. The terminal device sends the first message to a first network device in the first network. The first network device is an access and mobility management function network element or an access network device.

Abstract: A communication method and device are provided. A first message is received from a base-station central unit, where the first message is associated with determining whether a to-be-paged terminal device supports a first grouping manner and/or determining a paging manner for the to-be-paged terminal device. The terminal device is paged in a first paging manner that is determined based on the first message. A base-station distributed unit can determine, based on the first message, whether the to-be-paged terminal device supports a grouping manner or a grouping manner that can be supported by the to-be-paged terminal device. In this way, in a split architecture, the base-station distributed unit can also complete paging on the terminal device.

Abstract: A system service detects a first trigger event of a target application, loads an application program of the target application in response to the first trigger event, and transmits a communication address to the application program. The application program performs preloading, and waits to receive a message based on the communication address. The system service detects a second trigger event of the target application. The system service generates a startup instruction in response to the second trigger event of the target application, and sends the startup instruction to the application program. The application program receives the startup instruction by using the communication address, and starts the target application in response to the startup instruction.

Abstract: This application provides a method for configuring assistance information and a communications apparatus. A first network device sends a path switch request message to an access and mobility management function (AMF), where the path switch request message is used to request for switching least one radio bearer (RB) of a terminal device from a second network device to the first network device. The first network device receives a path switch request response message from the AMF. The first network device determines, based on the path switch request response message, first burst arrival time at which a downlink quality of service QoS flow arrives at an ingress of the first network device within a first periodicity, where the first burst arrival time is used for downlink scheduling.
