Abstract: An edge enabler server of an edge data network is configured to receive a verification request comprising an edge enabler client identification (EEC ID), wherein the EEC ID uniquely identifies an edge enabler client (EEC), determine whether the EEC ID is an authorized BEC ID and provide a verification response based on whether the EEC ID is authorized.

Abstract: A user equipment (UE) is configured to operate as an edge enabler client (EEC) and is configured to determine one or more application context relocation (ACR) methods supported by an application client (AC) of the UE and transmit, to an edge data network (EDN), a message comprising a first indication that the AC requires service continuity support, a second indication of one or more ACR methods supported by the AC and a third indication of one or more ACR methods supported by the EEC.

Abstract: Systems and methods of protecting an initial NAS message are described. The NAS message is encrypted using the home PLMN public key during initial registration with the network using a registration request message. An AMF of the serving PLMN sends a serving PLMN public key which is then used to encrypt information including an S-NSSAI of later initial NAS messages after initial registration is completed. The S-NSSAI may not be sent in the later initial NAS message if the S-NSSAI is provided at an access stratum level. The RRC message may contain an indication that the S-NSSAI is encrypted using the serving PLMN public key.

Abstract: A user equipment (UE) is configured to receive broadcast information from a cell of a public land mobile network (PLMN) including a parameter indicating support for disaster roaming, wherein the PLMN is a forbidden PLMN (FPLMN) for the UE, attempt a registration with the FPLMN by sending a registration request to the PLMN including a PLMN ID of a determined PLMN under disaster, receive a message including a cause code indicating the disaster roaming for the FPLMN is not allowed in a current tracking area (TA) of the cell for the determined PLMN under disaster, store a tracking area identifier (TAI) of the cell and prevent further registration attempts with the FPLMN for the determined PLMN under disaster when the UE is in the current TA.

Abstract: A user equipment (UE) is configured to receive broadcast information from a public land mobile network (PLMN) including at least a PLMN identifier (ID), attempt a registration with the PLMN by sending a registration request to the PLMN, wherein the UE attempts the registration via a base station operated by the PLMN deployed in a non-terrestrial network (NTN) arrangement including a non-terrestrial component configured to provide services to the UE via a service link, receive a message including a cause code indicating the PLMN is not allowed to operate at a current UE location and further including a set of attributes indicating further conditions wherein the registration with the PLMN is not allowed and avoid further registration attempts with the PLMN when the further conditions are met.

Abstract: Systems and methods of protecting an initial NAS message are described. Depending on whether a security context for a serving PLMN is stored, the UE uses either a public key from the serving PLMN or a key from the security context to encrypt parts of the initial NAS message. An initial NAS message containing the encrypted parts is then sent to an AMF of the serving PLMN. The serving PLMN public key is transmitted via a SIB. Prior to transmission of the initial NAS message or in parallel with it, an RRC message is sent to the base station. The RRC message contains the UE identifier and/or a NSSAI encrypted using the serving PLMN public key.

Abstract: Methods, systems, and storage media are provided for user equipment (UE) that supports enhanced coverage and may operate with a voice centric usage setting or a data centric usage setting. When the UE's usage setting is set to voice centric, the UE may not operate in coverage enhancement (CE) mode B. When the UE's usage setting is set to data centric, then the UE may operate in CE mode B. The UE may indicate the UE's usage setting in an Attach or Tracking Area Update (TAU) request message, and a mobility management entity (MME) may indicate to an evolved NodeB that CE mode B is restricted or not restricted based on the usage setting. Other embodiments may be described and/or claimed.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: receiving a request message from a user equipment (UE) served by a non-terrestrial access node, where the non-terrestrial access node is broadcasting a plurality of tracking area codes (TACs), and where a first TAC is associated with a first tracking area (TA) that is forbidden for the UE; and sending, to a core network node, the plurality of TACs in at least one information element.

Abstract: A user equipment (UE) configured to connect to an edge data network. The UE connects to a first edge application server (EAS) of an edge data network (EDN), the connecting comprising performing a first authorization/authentication procedure, receives a message indicating the UE is to connect to a second EAS of the EDN, the message including an indication as to whether the UE is to perform a second authorization/authentication procedure to connect to the second EAS and performs a discovery procedure to locate the second EAS based on at least the indication in the message.
