Validity of network slice-related information provided by dedicated signaling

Abstract

A wireless terminal communicates with an access node of a radio access network which supports one or more network slices. The wireless terminal comprises transmitter circuitry, receiver circuitry, and processor circuitry. The transmitter circuitry is configured to transmit a request message comprising one or more identifiers of requested network slices. The receiver circuitry is configured to receive, in response to the request message, a response message comprising one or more tracking area identities as a registration area (RA) and one or more network slice identifiers indicating allowed network slices in the RA. The receiver circuitry is further configured to receive a dedicated message comprising dedicated network slice-related information associated with the allowed network slices. The processor circuitry is configured to discard the dedicated network slice-related information upon occurrence of a predetermined event.
