    IPC: H04W60/02

    Abstract: A user equipment (UE) that initiates a periodic update timer, wherein the UE is configured to perform a periodic registration update procedure in response to a periodic update timer expiry event, identifies that the periodic update timer has expired, wherein the periodic update timer expiry event occurs when the UE is out of coverage, selects a cell to camp on, wherein the cell is known to be in a non-allowed area and initiates the periodic registration update procedure in response to the periodic update timer expiry event, wherein the UE delays the periodic registration update procedure until the UE enters a fifth generation mobility management (5GMM) operating substate associated with camping on the cell that is known to be in the non-allowed area

    Abstract: A user equipment (UE) transmits a registration request message to a first public land mobile network (PLMN), wherein the first PLMN is a roaming PLMN, receives a registration accept message from the first PLMN, determines that the registration accept message includes a manipulated steering of roaming (SoR) container or does not include a SoR container, wherein the SoR container is configured by a home PLMN (HPLMN) of the UE and transmitted to the first PLMN from the HPLMN, determines that the registration accept message includes an indication that the first PLMN does not support voice over packet switching (VoPS) and adds the first PLMN to a first list of PLMNs in which voice service is not possible in an N1 mode

    IPC: H04W68/00 ,  H04W48/02 ,  H04W76/18

    Abstract: If a paging or notification message is received by a user equipment (UE) when a UE-initiated 5GMM specific procedure or service request procedure is ongoing, a UE may buffer the paging or notification message. To buffer the paging or notification message, the UE may remember the pending mobile terminated transaction and re-attempt the registration or request procedure with the access category 0 (= MT_acc), if the ongoing UE-initiated 5GMM specific procedure or service request procedure fails due to access barring. If a 5GMM specific procedure or service request procedure is received by the network when a MT transaction is ongoing (i.e. a paging message with the access type set to 3GPP access or notification message via non-3GPP access with the access type indicating 3GPP access) the network may complete the incoming MT transaction and may remember the pending mobile terminated transaction and continue it once the MO transaction is completed.

    Abstract: There is provided a method for an access and mobility management function (AMF) in a wireless network, the method comprising: receiving, at the AMF, a registration request message from a user equipment (UE) the registration request message comprising a registration type parameter indicating a mobility registration update; in response to the registration request message, at the AMF, performing a mobility registration procedure for the UE in a visited public land mobile network (VPLMN) the registration procedure including receiving and storing UE context information at the AMF; determining that the UE context information includes a steering of roaming (SoR) indicator for mobility registration indicating that a unified data management (UDM) of a home public land mobile network (HPLMN) requests the VPLMN to retrieve SoR information in response to the registration type parameter indicating the mobility registration update when a SoR container has not been delivered to the UE in a previous registration; and in response to the SoR indicator for mobility registration, retrieving the SoR information from the UDM and delivering the SoR information to the UE in a registration accept message.
