Abstract: Location services for a user equipment (UE) are supported with a Network Exposure Function (NEF) serving as a focal point for any location request. An entity that needs the location of the UE sends a location request to the NEF in the home PLMN or Visited PLMN for the UE. The location request includes, e.g., a type of location request, a required location accuracy, a required response time or some combination of these. The NEF determines whether to use a Gateway Mobile Location Center (GMLC) or a serving Access and Mobility Management Function (AMF) for the UE to obtain the UE location based on the content of the location request and sends the location request to the GMLC or serving AMF accordingly. Additionally, if the serving AMF is used, a serving base station may obtain the UE location and send the UE location to the serving AMF.

Abstract: Techniques are described to support call routing and location for a user equipment (UE) with satellite wireless access to a serving PLMN. The UE sends a Session Initiation Protocol (SIP) INVITE message to a network node, such as a P-CSCF, that includes an indication of satellite access for the UE. In response the network node sends a request to another network node for a cell ID for a fixed cell in which the UE is located. The fixed cell can be independent of satellite radio cells for the serving PLMN. The network node may receive the cell ID for the fixed cell and sends the SIP INVITE message to another network node (e.g., an E-CSCF or LRF) with the cell ID for the fixed cell. The other network node may use the cell ID to route the SIP INVITE message or obtain an approximate location of the UE.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes registering with a first public land mobile network (PLMN) of a first network operator in response to detection of an interruption event associated with a second PLMN of a second network operator; determining that the interruption event has ended; and taking one or more actions to communicate with the second PLMN in response to the ending of the interruption event, wherein taking the one or more actions to communicate with the second PLMN is based on a constraint associated with access attempts to the second PLMN.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving voice over new radio (VoNR)-to-voice over long term evolution (VoLTE). An example method generally includes communicating with and camping on a next generation node B (gNB) in a 5G new radio (NR) system; initiating a voice call with the gNB; receiving a 5G NR-to-long term evolution (LTE) handover command in response to initiating the voice call; performing a handover procedure in response to the handover command; detecting a failure in the handover procedure; and taking one or more actions in response to detecting the failure in the handover procedure.

Abstract: Aspects of the present disclosure relate to a mechanism to enable interworking between fifth generation system (5GS) network slicing and evolved packet core (EPC) connectivity. In an example, techniques are provided for existing packet data unit (PDU) sessions that provide connectivity to a network slice from a set of network slices. Connectivity to the network slice is in response to a user equipment (UE), that uses network slices, moving between a 5G network and a 4G network. The existing PDU sessions are connected to a dedicated EPC core network that supports the same services provided by the network slice.

Abstract: Techniques for optimizing user equipment radio capability signaling for wireless communications are described. In one technique, a type of network to access for communications is determined. A capability identifier(s) associated with a set(s) of user equipment (UE) radio capabilities is determined based, at least in part, on the type of network. The capability identifier(s) is sent to the network. Upon receiving an indication of the capability identifier(s), the set(s) of UE radio capabilities associated with the capability identifier(s) is identified and stored.

Abstract: Certain aspects of the present disclosure provide techniques for network slice selection assistance information (NSSAI) signaling. A method that may be performed by a user equipment (UE) includes receiving a first message comprising one or more fields, each field indicating a network slice identifier via a plurality of bits. The method generally includes sending and/or receiving at least a second message referencing at least one field of the first message to indicate the network slice identifier via a reduced number of bits.

Abstract: Certain aspects provide a method for wireless communication. The method generally includes deriving a network specific identifier (NSI) in a network access identifier (NAI) format, the NSI including a network identifier (NID) stored at the UE, generating a subscription concealed identifier (SUCI) based on the NSI for authentication of the UE with a non-public network (NPN), and sending the SUCI to a network entity for the authentication of the UE with the NPN.

Abstract: Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. For example, in one aspect a wireless communication technique takes into account the load of a relay before a UE is switched from one relay to another. In another example, a wireless communication technique ensures that UEs are handed over to relays that will be able to serve the UE as the mobile relay continues to follow its expected path (such as streets or tracks), which may be known or determined.

Abstract: A method, operational at a device, includes receiving at least one packet belonging to a first set of packets of a packet flow marked with an identification value, determining that the at least one packet is marked with the identification value, determining to change a quality of service (QoS) treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received, and sending a request to change the QoS treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received to trigger a different QoS treatment of packets within the packet flow, responsive to determining to change the QoS treatment. Other aspects, embodiments, and features are also claimed and described.
