A method is disclosed in which a defined vendor specific extension is used to store an enterprise network identifier within a subscriber identity module (SIM). The use of the vendor specific extension makes it easier to provision a SIM (Subscriber Identity Module) profile with an enterprise identifier. The vendor specific extension allows the high level operating system (HLOS) of a UE (User Equipment) to obtain an enterprise identifier without impacting the baseband implementation of the UE. The same enterprise identification can be reused in equipment of both 4th Generation Long Term Evolution (LTE) and 5th Generation New Radio (NR) networks.

Embodiments of the present disclosure provide a network access authentication processing method and device. The method includes: receiving a confirmation message sent by user equipment, the confirmation message carrying a first signature token generated by the user equipment according to a first Privacy enhanced Mobile Subscriber Identifier (PMSI); verifying whether the first signature token is valid; and when the first signature token is invalid, obtaining the PMSI to perform network access authentication on the user equipment.

Embodiments of the present application provide methods for checking UE capability match, an AMF, a base station, and a storage medium. The method includes: determining to send a UE capability match request to a base station during a registration procedure initiated by the UE; sending a request for setting up a UE's access stratum (AS) security context to the base station, and sending the UE capability match request to the base station after it is determined that the base station completes setup of the AS security context; receiving a UE capability match acknowledgement returned from the base station. By the method according to the embodiment of the application, the problem that the base station does not respond to the UE capability match process requested by the AMF, which results in that the AMF cannot issue an indication of IMS voice over PS session to the UE during the registration process, can be avoided, and thus the UE can normally obtain IMS voice service.

This application provides a slice authentication method and an apparatus. One example method includes: initiating, by a first network function (NF), slice authentication between a terminal device and an authentication server for a slice; sending, by the first NF, identification information of a first network, identification information of the slice, and identification information of the terminal device to the authentication server, wherein the first NF is an NF in the first network; and receiving, by the first NF, a slice authentication result for the slice, the identification information of the slice, and the identification information of the terminal device from the authentication server.

A method for a UE to perform a MUSIM operation is provided. The method includes connecting to a first network associated with a first USIM; transmitting a request message to the first network, the request message including assistance information to request a time gap for the MUSIM operation; receiving a first time gap configuration from the first network in a case that a type of the time gap requested by the UE is aperiodic, the first time gap configuration indicating a starting SFN and a starting subframe of a first configured time gap; and in a case that the UE receives the first time gap configuration, switching to a second network, while keeping a connection to the first network, during the first configured time gap according to the first time gap configuration, the second network being associated with a second USIM.

Provided are a wireless communication method, a network device and a terminal device. The method includes: after acquiring a PSI parameter of a terminal device, a first network device determines whether to update policy information of the terminal device, wherein the PSI parameter is used for identifying a part of policy information for the terminal device under a subscribed user. In an implementation of the present disclosure, after acquiring a Policy Section Identifier (PSI) parameter of a terminal device, a first network device directly determines whether to update policy information of the terminal device.

A wireless User Equipment (UE) and an Access and Mobility Management Function (AMF) establish first and second active registrations and corresponding N1s. The UE and AMF deactivate the second active registration and establish a third active registration and corresponding N1. The UE and AMF exchange active N1 signaling for the first active registration and the third active registration. The UE and AMF exchange inactive N1 signaling for the second inactive registration.

A telecommunications network includes a serving network and a home network. In some examples the serving network receives, from the home network, identity data associated with a network terminal. The serving network determines a tied key using a tying key derivation function (TKDF) based on the identity data, then prepares an authentication request based on the tied key and sends the request to the terminal. In some examples, the home network receives the identity data from the access network and determines a tied key using a TKDF. The home network then determines a confirmation message based on the first tied key. In some examples, the serving network receives the identity data from the home network, and receives a network-slice selector associated with the network terminal. The serving network determines a tied key using a TKDF based on the identity data and the network-slice selector.
