    Abstract: Techniques discussed herein facilitate configuration of network slices for a User Equipment (UE) supporting constraints on simultaneous operation of slices. receiving a registration request message to request registration on a set of requested network slices; registering the UE to a set of allowed network slices; and generating a registration accept message for transmission indicating the UE is registered to the set of allowed network slices, wherein the registration accept message indicates slice compatibility information for each allowed network slice of the set of allowed network slices for the UE, wherein the slice compatibility information for each allowed network slice indicates whether or not other configured network slices of a set of configured network slices are compatible with the configured network slice for simultaneous operation by the UE.

    Abstract: Systems and methods for managing synchronization of protocol data unit (PDU) sessions between a user equipment (UE) and a network are disclosed herein. In some embodiments, a determination of whether a message comprising a PDU session status information element (IE) should be sent is based on previous messaging between peer entities of the network. In some embodiments, a determination that the peer entity is informed of a relevant PDU session status is made after expected reply messaging is received in response to prior messaging. In some cases, a reply message without a PDU session status IE is sent from one entity to a peer entity when it is determined that each entity has a matching PDU session status. Cases involving failures detected at the network, and cases where an entity activates a data radio bearer (DRB) of a PDU session that is inactive at its peer are also discussed.

    IPC: H04W12/06

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first authentication request in response to a first triggering request from the UE to a mobility management node of a first Tracking Area (TA) in which the UE is located. In some embodiments, the UE may prepare and store an authentication response according to the first authentication request. In response to determining that the UE has moved from the first TA to a second TA, the UE may abort a sending of the authentication response, and may send the stored authentication response according to the first authentication request to the mobility management node of the second TA in response to the receipt of the second authentication request and in further response to a determination that a given parameter of each of the first and second authentication requests are the same.

    Abstract: A technique for establishing a voice call including receiving an indication that the first wireless system supports emergency service fallback, receiving an indication to establish an emergency voice call, transmitting an emergency service request to the first wireless system, determining that an unexpected error has occurred, selecting a second wireless system based on the determination that the unexpected error has occurred, and connecting to the second wireless system to complete the emergency voice call. Additionally, a technique for cancelling a voice call including receiving an indication that the first wireless system supports emergency service fallback, receiving an indication to establish an emergency voice call, transmitting an emergency service request to the first wireless system, receiving an indication to cancel the emergency voice call, and cancelling a connection to a second wireless system.
