Abstract:
Certain aspects of the present disclosure relate to methods and apparatus relating to local area data network connectivity. In certain aspects, a method for use by a network device includes determining a set of available local area data networks (LADNs) for a user equipment (UE) based on a subscription of the UE to a set of data network names (DNNs) corresponding to the set of available LADNs and sending the UE information indicative of the set of available LADNs and a location of availability corresponding to each of the LADNs of the set of available LADNs.
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 handover from a next generation access network to a legacy access network may be performed via a next generation core network and a legacy core network. A handover request received at a next generation core network serving node may include an identifier of a target cell within the legacy access network. The next generation core network serving node may identify a legacy core network serving node to which the handover may be forwarded based on the target cell identifier. Packet data units may then be routed over the legacy access network and the next generation core network by mapping data flows in the next generation core network to packet data connections in the legacy access network.
Abstract:
Certain aspects of the present disclosure provide techniques for selecting policies for routing of data traffic. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes selecting at least one policy for routing of data traffic to a network, wherein the policy comprise an access network discovery and selection policy (ANDSP) if the UE has the ANDSP provisioned regardless of whether the UE is registered to evolved packet core (EPC) or fifth-generation core network (5GCN), and communicating the data traffic to the network based on the selection.
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:
Certain aspects of the present disclosure relate to methods and apparatus for handling mobility between areas with heterogeneous network slices in wireless communications systems operating according to new radio (NR) technologies. An exemplary method that may be performed by a UE includes receiving an indication that a network slice is not available, entering a connection management idle (CM-IDLE) state, and initiating a registration procedure with an access and mobility management function (AMF) subsequent to entering the CM-IDLE state.
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:
The present disclosure provides the UE with ePDG information that includes a list of networks that provide ePDG in the area where the WLAN access point is located. In an aspect, the list of networks may include a list of PLMN IDs. By receiving the ePDG information containing the list of networks that provide ePDG in the area where the WLAN access point is located, the UE may be prevented from selecting an incorrect ePDG. In aspects of the disclosure, a method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the apparatus associates with an access point of a wireless communication network. In another aspect, the apparatus receives, from the access point, ePDG information comprising a list of networks that provide ePDGs in an area of the access point. In a further aspect, the apparatus selects an ePDG based on the ePDG information.
Abstract:
In aspects of the disclosure, a method, an apparatus, and a computer program product for wireless communication are provided. In one aspect, the apparatus determines if a connection to a PLMN has been established. In another aspect, the apparatus builds a FQDN based on the determination by attempting to build the FQDN using each of the prioritized FQDNs in order of priority until the FQDN is built, building the FQDN using a PLMN ID of the PLMN if it is determined that the PLMN is found in the list, or building the FQDN based on the wildcard PLMN if it is determined that the list comprises the wildcard PLMN. Further still, the apparatus selects an ePDG based on the FQDN.
Abstract:
Aspects described herein relate to detecting wireless network services. A network that advertises access to a service provider network via a cellular radio access technology (RAT) in an unlicensed frequency can be discovered at a user equipment (UE). The UE can then determine one or more user-defined or operator-defined policies related to selecting the network, and select the network for access based at least in part on the one or more user-defined or operator-defined policies.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be aboard an aerial vehicle such that the UE is above ground, and in some cases, moving above ground (e.g., flying). The UE may determine to perform an emergency communication procedure (e.g., an emergency call) while the UE meets one or more flying state conditions, where the one or more flying state conditions may be indicative that the UE is in a flying state. The UE may transmit a message to a base station as part of the emergency communication procedure, where the message may be indicative that the UE meets the one or more flying state conditions. The UE may participate in the emergency communication procedure while the UE is in the flying state.
