Abstract: This application discloses a network slice admission control method. It includes a UE sends a registration request message, the registration request message carrying identification information of a network slice that the UE requests to access. When a quantity of UEs that access a network slice subject to admission control in the network slice that the UE requests to access is greater than or equal to a first threshold, the AMF sends a registration accept message that carries identification information of a first network slice that is allowed to access the first network slice. According to the method provided in this application, when the quantity of UEs that access the network slice subject to admission control in the network slice that the UE requests to access is greater than or equal to the first threshold, it can be ensured that the UE can successfully register with and access the network slice.

Abstract: Embodiments of this application provide a method for selecting an access network type, a device, and a system, to flexibly select an access network type. An example method includes: determining, by a policy control function PCF entity, that a network status of a first network does not meet a preset condition, where the first network is a network currently accessed by a terminal; and sending, by the PCF entity, an access network type corresponding to a second network to the terminal, where the access network type corresponding to the second network is used to instruct the terminal to redirect a session of the terminal to the second network, and the second network is a network other than the first network.

Abstract: A method and a device for performing communication by using a virtual subscriber identity module are used to provide a mode in which the device can perform communication without a SIM card. The method includes: receiving, by a first device, a virtual subscriber identity module data package sent by a second device by using a short range communications protocol, where the virtual subscriber identity module data package carries a virtual subscriber identity, and the virtual subscriber identity is used to uniquely identify a user using the first device when the first device performs communication in a network provided by a mobile communications operator; obtaining, by the first device, the virtual subscriber identity by using the virtual subscriber identity module data package; and communicating, by the first device by using the virtual subscriber identity, with another device in the network provided by the mobile communications operator.

Abstract: A session processing method includes determining, by a processor that a first application is not associated with a session parameter of a first session when starting the first application. The method also includes transmitting data of the first application through the first session in response to obtaining indication information. The indication information indicates that the session parameter of the first session can satisfy a session parameter requirement of the first application.

Abstract: The present disclosure relates to a slice-based communications method. In one example method, an access and mobility management function (AMF) node sends a first request message to a network slice selection function (NSSF) node. The AMF node receives a response message from the NSSF node. The AMF node obtains, based on the response message, allowed network slice selection assistance information (NSSAI).

Abstract: This application provides a slice information update method and an apparatus. The method includes: when determining that a network slice that was not supported by a PLMN is updated to be supported by the PLMN, sending, by a network slice selection network element, a notification message to a communications network element, where the notification message is used to indicate that the PLMN supports the network slice; and notifying, by the communications network element, a terminal that the PLMN currently supports the network slice. In this way, the corresponding terminal learns that the PLMN currently supports the network slice.
