Abstract: A method for accessing a network by UE, a network device, and first UE are disclosed. The first UE sends a first message, where the first message includes a message that second UE accesses a network by being associated with the first UE; and after an access response sent by the network device is received, the first UE and the second UE associated with the first UE access the network. After receiving the first message, the network device sends an access response to the first UE, to specifically allocate a transmission resource to a wearable device that needs to transmit data, so as to save network resources.

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.
