Abstract: A service transmission method and apparatus are provided to establish a connection between an access and mobility management function network element and a secondary base station, when a master base station is not capable of continuing to provide a service for a terminal device. In an embodiment, an access and mobility management function network element determines that a master base station is not capable of continuing to provide a service for a terminal device. The access and mobility management function network element sends a mobility management context of the terminal device to a secondary base station, where the mobility management context is used by the secondary base station to perform mobility management on the terminal device. Therefore, a signaling connection between the access and mobility management function network element and the secondary base station can be quickly established, thereby ensuring service transmission and improving user experience.

Abstract: The present disclosure relates to communication methods and communication apparatuses. In one example method, a first data analytics network element receives first information of an application from a first network element, where the first information includes at least one of first application description information or an application status that correspond/corresponds to the application. The first application description information includes an application identifier and first IP information that correspond to the application, and the application status includes a foreground state or a background state of the application. The first data analytics network element determines second information based on the first information. The first data analytics network element sends the second information to a second network element.
