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.

Paging collision with 5GMM specific procedure or service request procedure

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.

Handling PLMN prioritization

Techniques are provided for managing the provisioning of voice services to a user equipment (UE) in a fifth generation (5G) network. For example, the UE generates a registration request message that includes 5G mobility management (5GMM) capabilities of the UE that are indicative of whether the UE supports voice over internet protocol multimedia subsystem (IMS), and transmits the registration request message to a next generation radio access network (NGRAN) node in the 5G wireless network. Based on the 5GMM capabilities, the NG-RAN node can determine whether voice over IMS can be provided to UE by comparing the 5GMM capabilities to capabilities of the NG-RAN node.

Method, computer readable medium and apparatus to determine support of IMS voice service in a 5G mobile network

Apparatuses, systems, and methods for Reflective Quality of Service (RQoS) enhancements. Methods may include enhancements for both UE behavior and network function behavior. Network function behaviors may include enhancements to UPF behavior and SPF behavior. Enhancements to RQoS may include methods for resetting an RQoS indicator (RQI) bit for downlink packets of a flow destined for a UE, methods for generating a flow ID to include in a SDAP header destined for a UE, methods for using the flow ID to limit L3 and L4 header parsing, methods for sending/receiving feedback regarding processing of the RQI bit, methods for maintaining a QFI mapping table, methods for skipping parsing of SDAP header fields, methods for specifying and signaling a QoS Flow Identifier (QFI) range to a UE, methods for limiting downlink header parsing, methods for updating a QFI, and methods for performing high efficiency RQoS processing.

Reflective QoS enhancements

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.

Network selection in a non-terrestrial network

Some embodiments include an apparatus, method, and computer program product for public land mobile network (PLMN) selection for disaster roaming in a 5G wireless communications system. A user equipment (UE) can receive two or more messages that disaster roaming service is offered by two or more forbidden public land mobile networks (PLMNs) of a forbidden PLMN list of the UE. The UE can select a first forbidden PLMN of the two or more forbidden PLMNs, where the first forbidden PLMN corresponds to a highest priority PLMN of a preferred PLMN list of the UE, and establish communications, via the transceiver, with the first forbidden PLMN. Some embodiments include designating a forbidden PLMN as offering a disaster roaming PLMN for manual selection. Some embodiments include enabling a Closed Access Group (CAG)-capable UE to access disaster roaming services from a forbidden PLMN of a CAG-only cell or a 5G cell.

Public land mobile network selection for disaster roaming

Apparatuses, systems, and methods for reducing wireless device service interruptions. An indication of a disaster condition may be provided to a wireless device. The disaster condition may affect a home public land mobile network of the wireless device. The wireless device may perform cell selection in a manner influenced by the indication of the disaster condition. This may include considering cells associated with a forbidden public land mobile network for the cell selection, or excluding cells associated with the home public land mobile network of the wireless device that are unavailable, for example due to the disaster condition, among various possibilities.

Reducing wireless device service interruptions

A mobile radio communication system having a mobile radio communication network and a mobile radio subscriber appliance, wherein a unit in the network layer of the core network of the mobile radio communication network is configured to transmit to the mobile radio subscriber appliance a first message, based on an occurrence of a predetermined event, with a request for a statement which describes at least one radio characteristic of the mobile radio subscriber appliance.

Mobile radio communication system

Apparatuses and computer-readable storage media for handling timers for mobile terminated circuit-switched fallback (MT CSFB) calls. An apparatus for a user equipment (UE) includes processing circuitry operably coupled to a data storage device. The data storage device is configured to store a value of an extended service request for mobile terminated services (EXT-MT) timer. The value of the EXT-MT timer is less than a value of a guard timer of a Visitor Location Register (VLR). The processing circuitry is configured to start the EXT-MT timer and generate an extended service request message to be transmitted to a Mobility Management Entity (MME) responsive to a paging for an MT CSFB call, and attempt to select a radio access technology of a different type of network if the EXT-MT timer expires before the UE successfully performs inter system change and a circuit switched fallback cancellation request was not received from a subscriber.

Handling of timer expiry for MT CSFB

A method and a mobile device configured, when in idle mode, to select a target frequency from a network in response to a redistribution information from the network, including starting an evaluation timer; performing measurements on a first set of frequencies throughout a duration of the evaluation timer; selecting the target frequency based on the measurements of the first set of frequencies; and starting a second timer, which is distinct from the evaluation timer, during which time the device performs measurements on a second set of frequencies comprising the target frequency.

Communication device and a method for operating a communication device

A method for establishing a communication connection includes transmitting an identification for identifying a first communication device to the first communication device or a second communication device via a packet-switched first communication connection between the first communication device and the second communication devices, and using the identification to establish a circuit-switched second communication connection between the first communication device and the second communication device.
