Abstract: The present invention discloses an inter-RAT cell reselection method, a terminal, and a network side device. The method is: sending, by a terminal, a first request message to a first base station, where the first request message carries first cause indication information, the first cause indication information indicates that the terminal needs to perform a cell reselection process from a second base station to the first base station, the first base station is located in a first radio access technology (RAT) system, the second base station is located in a second RAT system, the terminal is in a first connected mode when connecting to the second base station, and the first RAT system does not support the first connected mode; and receiving, by the terminal, an acknowledgement returned by the first base station for the first request message, and switching the first connected mode into a second connected mode based on the acknowledgement, where the first RAT system supports the second connected mode.

Abstract: An access network device determines a first system information block and a second system information block of a cell, where the first system information block includes identifiers of n networks supporting external authentication, the second system information block includes identifiers of m groups and n bitmaps, the n bitmaps are sequentially in a one-to-one correspondence with the identifiers of the n networks included in the first system information block, each bitmap indicates a group supported by a corresponding network, m bits included in each bitmap are sequentially in a one-to-one correspondence with the identifiers of the m groups, and each bit indicates whether the corresponding network supports a group corresponding to the bit. The access network device sends the first system information block and the second system information block to a terminal device.

Abstract: A method includes receiving cell reselection information from a radio access network device. The cell reselection information includes an identifier of at least one carrier frequency, an identifier of a network slice supported by each of the at least one carrier frequency, and priority information corresponding to the identifier of the network slice that is information of a specific service type of the network slice or a network slice set identifier corresponding to the network slice. The method further includes in response to the terminal device performing cell reselection, selecting a cell on a carrier frequency of the network slice supported by the terminal device as a reselected to-be-camped cell based on the identifier of the at least one carrier frequency, the identifier of the network slice supported by each of the at least one carrier frequency, and priority information corresponding to the identifier of the network slice.

Abstract: Example access control methods and apparatus are described. One example method includes receiving an initial user equipment (UE) message by a core network device from an access network device. The core network device sends an initial context setup request message to the access network device, where the initial context setup request message includes one or more of the following information: public network integrated non-public network (PNI-NPN) identification information of a PNI-NPN accessible by a terminal device, a public land mobile network (PLMN) identity of a PLMN accessible by the terminal device, or an indication of whether the terminal device is allowed to access a network only by using a closed access group (CAG) cell.
