Abstract: A communication method and a communications device are provided. In the method, a first base station receives a first message; the first base station determines, based on the first message, whether to allocate a new RNA to a terminal in an inactive state; and the first base station allocates a new RNA to the terminal in the inactive state after determining to allocate a new RNA to the terminal in the inactive state, so as to reduce signaling overheads; and/or the first base station receives a second message; the first base station determines a communication status of the terminal in the inactive state based on the second message; and after determining that the terminal needs to change the communication status, the first base station controls the terminal to change the communication status.

Abstract: A data processing host includes a program running environment and a first isolation environment. The first isolation environment is isolated from the program running environment. The host operates in a non-secure mode in the program running environment, and operates in a secure mode in the first isolation environment. The program running environment includes a virtual instance operating in the non-secure mode, and the first isolation environment corresponds to the virtual instance in the program running environment. The first isolation environment includes an operating system in the secure mode and a resource allocated to the first isolation environment and comprising a first isolation space for running the operation system and a secure processing program, which corresponds to a program in the virtual instance and is for processing to-be-processed data.

Abstract: Example communication methods and apparatus are described. One example method includes sending a first handover request by a source base station to a core network device, where the first handover request is used to request to hand over a current session of a terminal from the source base station to any one of at least one base station, and the first handover request includes information about the at least one base station. The source base station receives a first handover response message from the core network device, where the first handover response message includes indication information, and the indication information is used to indicate whether a first base station of the at least one base station supports a network slice corresponding to the current session of the terminal device.
