Abstract: Mobile devices may receive page transmissions that include information related to a service for which the mobile device is being paged. The mobile device may be provided with a policy that describes a priority of radio access technologies (RATs) based on the type of service for which the mobile device is being paged. The mobile device, based at least in part on the service information, may access one or more of the wireless communications networks based on the identified service and/or based on the policy. A page transmission may include an indication of a RAT that is to be used for the page response and/or an index into the policy. A base station that transmits a page transmission may include an identifier of a particular network that is to be accessed in response to the page.

Abstract: Methods, systems, and devices for wireless communication are described. Relocation of a user plane may be minimized through the exchange of communication session information between network nodes. For example, a connectivity session manager and an access and mobility manager may exchange information associated with a user equipment (UE) communication session to prevent unnecessary reestablishment of an existing communication session. In such cases, the access and mobility manager may receive a session management request from a UE and send a request including the session management request to the connectivity session manager. Based on the received message, the connectivity session manager may identify a continuity mode, select a user plane anchor for the communication session, and send a response message to the access and mobility manager. In some examples, the connectivity session manager and the access and mobility manager may exchange session area codes associated with the location of the UE.

Abstract: A core network (CN) may establish and distribute a quality of service (QoS) policy across a wireless communication system, e.g., by sending QoS policy information to an access network and to user equipment. The QoS policy may be implemented with respect to data network (DN) sessions as well as data sessions. For each DN session or data session, the QoS policy may be applied by explicit or implicit request, and data sessions may in some examples utilize pre-authorized QoS policies without the need to request the QoS. Other aspects, embodiments, and features may also be claimed and described.

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: Methods, systems, and devices for wireless communication are described that provide for identification, on a per-PLMN basis of a type of core network associated with each PLMN in a list of networks associated with a base station. A user equipment (UE) may receive the list of networks and, based at least in part on the type(s) of core network accessible via each PLMN and a capability of the UE, initiate a connection establishment with a PLMN and associated core network. In some cases, UEs that are not capable of connections with a first type of core network (e.g., a 5G core network) may be restricted from camping on a cell or PLMN that may provide only connections with the first type of core network (e.g., a 4G core network).

Abstract: In an aspect, a network may support a number of client devices. In such a network, a client device transmits a request to communicate with a network, establishes a security context, and receives one or more encrypted client device contexts from the network. An encrypted client device context enables reconstruction of a context at the network for communication with the client device, where the context includes network state information associated with the client device. The client device transmits a message (e.g., including an uplink data packet) to the network that includes at least one encrypted client device context. Since the network device can reconstruct the context for the client device based on an encrypted client device context, the network device can reduce an amount of the context maintained at the network device in order to support a greater number of client devices.

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: Features pertain to determining, at a client device, to send a query to a network access node. The query may be associated with a plurality of serving networks, each serving network identified with a serving network identifier. A first serving network identifier may be selected to associate with the query. The query may be sent to the network access node. The query may include the first serving network identifier, and in some aspects, a second serving network identifier. Additional features pertain to receiving, at a network node, a query including a first serving network identifier. The network node may be associated with a plurality of serving networks. A first server to which to forward the query may be determined at the network node. The first serving network identifier identifies the first server. The query may be sent to the first server.

Abstract: Mobile devices may be paged via non-cellular or cellular radio access technologies (RATs). Mobile devices may determine that they are capable of receiving a paging message via a non-cellular RAT, and they indicate to a network that they are capable of such paging. Accordingly, in addition to cellular paging, mobile devices may be paged for cellular or non-cellular data via a non-cellular RAT. Non-cellular paging may be facilitated by a non-cellular paging server, which may be an independent network-side entity or may be an aspect of another network entity, such as an mobility management entity (MME).
