Abstract: Methods and apparatus supporting multiple concurrent service contexts sharing a single connectivity context are disclosed. A device may initiate a radio link with a network node and establish a connectivity context with the network node over the radio link using a connectivity logical context of the device. The network node may receive, authenticate, and authorize context establishment requests. A first service context with a first service management entity may be established over the radio link using a first logical context of the device, where the first logical context is distinct from the connectivity logical context. Multiple service connections using multiple service contexts based on multiple logical contexts of the device may share the connectivity context and may be established over the radio link.

Abstract: A gateway device detects a trigger associated with a device and, in response, identifies an application service associated with the device, obtains a traffic network policy associated with the application service, and obtains a network access token based on the traffic network policy. The network access token facilitates validating and/or mapping a downlink data packet obtained at the gateway device in user-plane traffic that is destined for the device. The network access token is sent to an entity in control-plane signaling. Subsequently, the gateway device obtains a downlink data packet including the network access token. The gateway device verifies the network access token and/or maps the downlink data packet to the device using data obtained from the network access token. The network access token may be removed from the downlink data packet before the downlink data packet is sent to the device according to the mapping.

Abstract: According to one aspect, a method includes obtaining, at a device, a plurality of contexts with a plurality of serving nodes. Each of the plurality of contexts may be associated with a context-unique identifier. Each context-unique identifier may uniquely identify one context in the plurality of contexts and be associated with data corresponding to a respective context. The data may be sent via the plurality of contexts via a radio link shared by the plurality of contexts. According to another aspect, a method includes associating each of the plurality of contexts with a separate set of credentials. Each set of credentials uniquely identifies one context and may be associated with data corresponding to a respective context. The data corresponding to a respective context may be encrypted based on the set of credentials associated with the context and sent via a radio link shared by the plurality of contexts.

Abstract: A client device may determine whether to obtain an element of information related to a service parameter from an access node. The access node may be associated with a plurality of connectivity access networks. The element of information can be selected and associated with a query. The query can be derived and configured according to one of a plurality of modes. The query can be sent as an over-the-air message to the access node. A service query protocol (SQP) server may be coupled to the access node. The query may be obtained at the SQP server from client device via the access node. A response to the query may be derived based on the element of information associated with the query and the mode of the query. The response may be sent from the access node to the client device.

Abstract: Systems, methods, and apparatuses for controlling offloadability of public data network (PDN) connections to wireless local area networks (WLANs) and detach from cellular wireless networks are described herein. An apparatus for wireless communication comprises a receiver configured to receive a first indication from a cellular wireless network that the apparatus may selectively offload all data connections except one between the apparatus and the cellular wireless network to the non-cellular wireless network. The apparatus further comprises a processor configured to selectively offload at least a subset of the data connections to the non-cellular wireless network based on the first indication. The receiver may further be configured to receive a second indication indicating that all data connections between the apparatus and the cellular wireless network may be offloaded to the non-cellular wireless network.

Abstract: Systems and methods for operator controlled APN routing mapping are described herein. In one embodiment, a method for routing policy evaluation in a wireless communication system comprises receiving, from a home network, a message comprising a home network policy associated with network node routing, and receiving, from a visited network, another message comprising a visited network policy associated with network node routing. The method also comprises evaluating the home network policy to determine whether to route data traffic via one of a wireless node offload or a designated access point name (APN), evaluating the home network policy to determine whether the home network policy has priority over the visited network policy, and ignoring a rule of the visited network policy associated with routing the data traffic in response to a determination that the home network policy has priority.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a network may establish a multiple access (MA) packet data unit (PDU) session for a local area data network (LADN) and may reconfigure a registration area to map to a LADN service area. A network may establish an MA PDU session for an LADN, but may steer traffic to only one of two access links. A network may reject a request for an MA PDU if it is for an LADN. A user equipment (UE) may be configured to trigger a UE registration update or other location information if it leaves an LADN service area while in an idle mode with one access network and a connected mode with the other access network. A UE may request LADN registration, and the network may provide the UE with an indication that MA PDU sessions for the LADN are not supported.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor one or more first conditions pertaining to non-cellular communications between the UE and a non-cellular network while the UE is operating in a dual networking mode for steering, switching, or splitting traffic (e.g., an access traffic steering, switching, and splitting (ATSSS) mode) between the non-cellular network and a cellular network. The UE may predict an availability status of at least the non-cellular network based on at least one of the one or more first conditions. In some cases, the UE may determine whether to change dual networking modes based on the availability status and may communicate in accordance with the same or a different dual networking mode using at least one of the cellular network, the non-cellular network, or a combination thereof based on the prediction.

Abstract: Disclosed are techniques for wireless communication using satellite access to a wireless network, where a wireless cell supported by a satellite is moving or temporarily fixed. In an aspect, a radio access network (RAN) entity or a user equipment (UE) provides, to a core network entity, an enhanced cell global identifier (CGI), where the enhanced CGI includes at least one field representing a location of the UE. Based on the enhanced CGI, the core network entity determines a location of the UE, and may provide a service to the UE based on the location. A core network may also provide an enhanced CGI to a RAN, e.g., to support wireless emergency alerting to UEs.
