Title: NETWORK ACCESS METHOD, TERMINAL, ACCESS NETWORK, AND CORE NETWORK
Abstract:
The disclosure discloses a network access method, a terminal, an access network, and a core network, which belongs to the field of technologies. The method comprises: acquiring a network service identifier of a requested network service; acquiring access information according to the network service identifier, the access information comprising a network slice identifier and a network slice type identifier corresponding to the network service identifier; determining an access mode corresponding to the network slice identifier according to the network slice type identifier; and accessing a network slice corresponding to the network slice identifier according to the access mode corresponding to the network slice type. The terminal in the present disclosure acquires, according to a network service identifier, access information that comprises at least a network slice type identifier, and then accesses a network slice according to an access mode corresponding to the network slice type identifier, thereby preventing the problem in which the terminal cannot acquire services due to a failure to access the network slice, and improving the service quality.
