Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) using a location server and service based interfaces (SBIs) and SBI service operations in a Fifth Generation wireless network. The location server may be, e.g., a Location Management Function (LMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may receive a location service request for the UE using an SBI and may communicate with another entity in the network, through a second entity and using an SBI, to obtain location information for the UE measured by the other entity. The LMF may determine a location for the UE based on the location information.

Abstract: Certain aspects of the present disclosure relate to techniques selecting a core network. As described herein, a user equipment (UE) may receive an indication of services provided by a first core network (CN). The UE may take action to reselect from the first CN to a second CN to access a set of services not provided by the first core network. When a UE desires services not available on a currently-connected CN, the UE may transmit an establishment request message requesting the services desired.

Abstract: Wireless communications systems and methods related to on-demand ultra-reliable, low-latency communication (URLLC) are provided. In one embodiment, a base station (BS) receives, from a user equipment (UE) in a first cell frequency, a request for a protocol data unit (PDU) session over a network slice. The BS receives, from a core network entity, a resource configuration request for the PDU session over the network slice. The BS transmits, to the core network entity, a resource configuration response indicating a cause for rejecting the resource configuration request. In one embodiment, a UE transmits, in a first cell frequency of a network, a network registration request message requesting a network slice of the network that is not provided by the first cell frequency. The UE receives a network registration response message indicating the network slice is allowed based on a second cell frequency of the network providing the network slice requested.

Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a connectivity request originated by a user equipment towards a next generation core network may be processed by the next generation core network. The next generation core network may then provide the user equipment an indication of whether the next generation core network supports an inter-RAT handover between the next generation RAT and a legacy RAT.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communications system may support techniques for efficient communication between a user equipment (UE) and different entities (or functions) of a core network. Specifically, the UE may interact with a single entity (or function) of a core network (e.g., an access and mobility management function (AMF)), and messages intended for other entities (or functions) may be routed appropriately by this entity. For example, an AMF may receive a message from a UE intended for another entity (or function) of the core network, and the AMF may transmit (or route) the message to the entity (or function). Similarly, the AMF may receive a message from another entity (or function) of the core network, and the AMF may transmit (or route) the message to the UE.

Abstract: A core network receives data from at least one of an Application Function (AF), a Data Network (DN), or a User Equipment (UE). A Session Management Function (SMF) processes the data for transport with a low overhead as a session management (SM) payload over a Non Access Stratum (NAS) protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as a SM payload. The data may be received as uplink data from a UE, e.g., in an SM payload. The SMF may processed the SM payload to obtain the data and may transport the data to the AF or DN. The SMF may perform IP header compression, data encryption based on an SMF encryption key, and/or buffering of data for a UE in an idle mode.

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.

Abstract: A UE may move out of range of a network. Accordingly, the UE may use a relay node to communicate. To manage the relay node, a wireless device such as the UE may receive a relay search message from a second UE requesting a relay UE to establish a connection to the network through the relay UE. The UE may transmit a message to a base station informing the base station of the relay search message from the second UE. The UE may receive an initiate relay association procedure message from the base station, the initiate relay association procedure message informing the first UE that the first UE has been selected by the base station to initiate a relay association procedure with the second UE. The UE may transmit a relay association message to the second UE including a request to be the relay UE for the second UE.

Abstract: Methods, systems, and devices for wireless communications are described that supports connectivity to a core network via an access network. A user equipment (UE) may establish connectivity with an access network and perform a discovery procedure to identify and select a packet data gateway that provides connectivity to a core network via a core network node. The UE may perform an authentication procedure with the core network node via the packet data gateway to be authenticated with the core network for establishing connectivity with the packet data gateway. The UE may receive a set of control plane addressing information via the packet data gateway corresponding to a secure tunnel established between the UE and the packet data gateway. The UE may perform an attach procedure via the secure tunnel with the core network node without re-authenticating the UE.
