Abstract: This application provides a data route selection method and apparatus, and relates to the field of communications technologies, so as to resolve a problem of an excessively long transmission delay for an application program that initiates a data transmission request relatively later. The data route selection method includes: detecting, by a terminal, that information about an application matches a traffic descriptor; determining, by the terminal, a first route selection components for the application; and routing, by the terminal, traffic of the application on a first protocol data unit PDU session. The first PDU session matches the first route selection components. This application is applicable to a terminal.

Abstract: A registration method includes sending, by a terminal, a first message to the AMF entity, where the first message includes first information, first network slice selection information, second network slice selection information, and information for requesting to establish a protocol data unit (PDU) session. The first network slice selection information is used by the AMF entity to select a first session management control function (SMF) entity, and the second network slice selection information is used by the AMF entity to select a second SMF entity. The method further includes receiving, by the terminal, a second message from the AMF entity, where the second message includes second information, and the second information includes PDU session establishment accept information.

Abstract: A connection management method includes: accessing, by UE, a network using a first base station, where the UE is in an RRC inactive state; accessing, by the UE, a network using a second base station, where the second base station does not support the RRC inactive state; and sending, by the UE, a first request message to a first core network entity using the second base station, so that the first core network entity releases a connection to the first base station based on the first request message.
