Abstract: A method for a re-authentication of user equipment (UE), by at least a portion of a core network (CN), for steering of roaming (SoR) data delivery, includes receiving, through next generation radio access network (NG-RAN) and/or 5G system (5GS), a subscriber data management (SDM) data request for a UE. The method includes determining that re-authentication of the UE be requested. The method includes encoding a response for transmission to the UE responsive to the SDM data request. Determining that re-authentication be requested can include determining that SoR data is being sent to the UE.

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: 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: Embodiments of the present disclosure describe methods, apparatuses, and systems for management of voice services for user equipments (UEs) in coverage enhancement (CE) mode B. A cellular protocol stack (CPS) of the UE may indicate to an internet protocol (IP) multimedia services (IMS) circuitry of the UE that the UE is operating in the CE mode B (or will be operating in the CE mode B when it awakes from idle mode). The IMS circuitry may receive an SIP invite from an IMS server to invite the UE to engage in a mobile terminated (MT) call. In response to the SIP invite, the IMS circuitry of the UE may reject the SIP invite and deregister the UE from voice services. Other embodiments may be described and claimed.

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) explicitly accounts for a coverage enhancement (CE or sometimes called enhanced coverage) feature in a public land mobile network (PLMN) search and/or selection. By explicitly using CE indicators in PLMN search and/or selection, a UE can determine whether to use a PLMN that may only be available in CE mode for voice services or data services, or fail to meet criteria, such as high data rate, that cannot be provided in CE mode. For example a UE can use the PLMN search and/or selection with (1) automatic PLMN selection at switch-on or recovery from lack of coverage, (2) higher priority PLMN selection, (3) manual PLMN selection, and/or (4) limited service capabilities while in CE mode.
