  • Publication number: 20240188024
    Abstract: Methods, apparatuses, and computer program products are described that support non-uniform network slice deployment across a service area of a registration area or tracking area covered by at least a radio access network. A network function transmits a plurality of tracking area codes associated with a network to user equipment to indicate primary and secondary tracking area codes to the user equipment. Selection of a tracking area code may be completed by the user equipment based on the primary and secondary tracking area codes and a forbidden tracking area identities list. The user equipment may be blocked from receiving services from a network slice based on the service area in which the user equipment attempts to access the network slice. Network functions may limit reporting of tracking area codes to user equipment based on a serving cell identity. Network slices may be restricted to private networks.

  • Patent number: 11956748
    Abstract: A determination is made that a registration attempt by a UE with a cell of a wireless network has failed when the UE is in a current tracking area. The UE updates a first list with indications(s) corresponding to the cell and an indication of the current tracking area, and the UE uses the first list for additional registration attempts. A network node sends, toward the UE, a request for the UE to store information, the storing to be in response to registration attempts by the UE with cells of the wireless network having failed while in corresponding tracking areas. The information is to include indication(s) corresponding to the cells and corresponding indication(s) of the tracking areas for the cells. The network node receives, in response to a successful secure connection having been performed between the wireless network and the UE, the information from the user equipment.
