    Abstract: A user equipment (UE) may detect that two or more of the slices that were requested by the UE cannot be served by the same access and mobility management function (AMF). Once the UE is able to determine that the multiple requested slices cannot be served by the same AMF, the UE may account for this incompatibility. For example, the UE may decide to only request compatible slices, or the UE may execute procedures with the network that allow the UE to simultaneously communicate with multiple AMFs. By allowing the UE to communicate with multiple AMFs, the UE may be able to utilize separate AMFs to register to slices that cannot be served by the same AMF. The system may allow for the UE to be paged by multiple AMFs.

    Abstract: User equipment (UE) may detect a disaster condition, and the resolution thereof, based on broadcast information, RRC messaging, NAS messaging, the ability to connect to an allowable PLMN, and indications from forbidden PLMNs. In a disaster condition, a UE may perform an enhanced PLMN selection procedure wherein, for example, the UE will not consider PLMNs that are in a disaster situation if the disaster situation applies to a current location of the UE, prioritize forbidden PLMNs for disaster roaming connection. For disaster roaming connection, the UE may be configured by an otherwise forbidden PLMN with information about what services the UE can access and what type of authentication procedure the network is able to perform with UE. Upon detecting that the disaster condition is over, the UE move back to an allowable PLMN.

    Abstract: A wireless transmit/receive unit (WTRU) may send to a network node a registration request message requesting to register with the network and indicating that the WTRU is capable of preserving, when the WTRU becomes unavailable to the network, context information associated with the communications between the WTRU and the network. The network node may indicate in a registration accept message that the network supports the preservation of context information when the WTRU becomes unavailable to the network. Based on a determination that the WTRU will become unavailable to the network, the WTRU may send to the network a message indicating a request to preserve the context information. The message may comprise an indication of a time period during which the WTRU will be unavailable.

    Abstract: Method and apparatus are for coordinating data flows from multiple user apparatuses, WTRUs, in a coordinated communication group. A method comprising receiving, by a non-access stratum, NAS, layer of a wireless transmit/receive unit, WTRU, and from an application server, a coordination identifier; sending, by the WTRU and to a core network entity, a request to establish a protocol data unit, PDU, session, wherein the request comprises the coordination identifier; receiving, by the WTRU, configuration information associated with the coordination identifier and the PDU session, wherein the configuration information comprises one or more rules associated with the PDU session that are to be coordinated with one or more rules associated with other PDU sessions; and receiving, by the WTRU, from the core network entity, a message indicating establishment of the PDU session.

    Abstract: Methods and apparatuses are described herein for providing fine-grained QoS rules within UE Policies. A network entity may receive triggers to update the policies of a user equipment (UE) with parameters based on input such as input from a third party. The network entity may derive fine-grained quality of service (QoS) rules and corresponding QoS Profiles and delivers them to the UE using a UE Policy container via the Non-Access Stratum (NAS). The fine-grained rules may comprise: a destination fully qualified domain name (FQDN) or uniform resource locator (URL), an Application ID, a User Route Selection Policy precedence value, etc. The fine-grained rules also provide mechanisms for time gating or volume gating. The UE may request new QoS treatment resulting in UE Policy update and may use the information in the fine-grained QoS rules when establishing or modifying PDU Session to apply QoS Flow Identifier (QFI) marking.
