A UE may receive a first GUTI from a network. The UE may transition to a Connected mode in response to a paging procedure with the network. The UE may take actions to ensure that a second GUTI is obtained from the network. Other aspects are described.

Enhanced user equipment security against attacks in a 4g or 5g network

A user equipment (UE) is configured to transmit a first registration request to a network, receive a registration accept message in response to the first registration request comprising a rejected network slice and an indication of a rejection cause corresponding to the rejected network slice and transmit a second registration request to the network comprising a requested network slice, wherein the requested network slice and the rejected network slice are a same network slice.

Network slice allocation and network slice rejection

A user equipment (UE) is configured to transmit a registration request to a first base station of a cellular wireless network, wherein the first base station operates on a first frequency band, the registration request including a first indication of one or more preferred network slices and receive a registration response from the first base station, the registration response including (i) a second indication of whether the one or more preferred network slices are accessible on the first frequency band and (ii) a third indication of where the UE can access any unsupported one or ones of the one or more preferred network slices.

UE-preferred network slice management

This disclosure relates to techniques for performing wireless communications in context of unified access control. A UE may enter an update needed state. The UE may detect a pending communication. The UE may access the network using an access category associated with the pending communication. The UE may complete the update.

Unified access control improvements

Apparatuses, systems, and methods for reducing wireless device service interruptions. An indication of a disaster condition may be provided to a wireless device. The disaster condition may affect a home public land mobile network of the wireless device. The wireless device may perform cell selection in a manner influenced by the indication of the disaster condition. This may include considering cells associated with a forbidden public land mobile network for the cell selection, or excluding cells associated with the home public land mobile network of the wireless device that are unavailable, for example due to the disaster condition, among various possibilities.
