Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may include a service discovery indicator in a broadcast message. A user equipment (UE) may tune to the radio frequency spectrum band of the AP and receive the broadcast message. The UE may identify a web resource based on the service discovery indicator and access the web resource to determine the capability configuration of the AP. The UE may access the web resource using an existing internet connection of its currently serving AP.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may attempt to access a network at a local area network access point without prior context information. The access point may be a hotspot operating in unlicensed spectrum according to a Long Term Evolution (LTE)-based standard. The UE may be unable to determine if it is authorized to access the network, so the UE may attempt to obtain system information that provides a list of service providers supported by the network. The UE may then determine whether it has credentials for a supported service provider, and the UE may access the network using those credentials when a supported service provider is recognized. Other broadcast messages may provide information about system information for supported service providers. A UE that is unable to access the network using stored credentials may attempt access using a random access channel procedure.

Abstract: Methods, systems, and devices for enhanced neighbor discovery through enhanced automatic neighbor relations (ANR) and for detecting cell identifier confusion and are described. Neighboring base stations may provide information to one another, including using ANR, that may avoid or help to resolve cell identity confusion. For example, a NHN-ID may be defined to avoid or resolve cell identify confusion. A wireless device, such as a base station or a user equipment (UE), may determine whether neighboring cells are using a common cell identifier and may adjust operations accordingly. For example, a device may detect physical cell identity (PCI) confusion by determining whether two neighboring cells have the same PCI and different Evolved Universal Terrestrial Access Network (E-UTRAN) Cell Global Identifiers (ECGIs) or different Neutral Host Network Identifier (NHN-IDs). A network entity may then inform the neighboring cells having the same PCI of the confusion.

Abstract: A neutral home network (NHN) may support home-routed traffic between a user equipment (UE) and a network of a mobile network operator (MNO) associated with the UE. The NHN may transmit an access point name (APN) that indicates a public land mobile network (PLMN) identifier (ID) to the UE. If the NHN supports home-routed traffic, the NHN may transmit an APN that indicates an MNO PLMN ID. If the NHN does not support home-routed traffic, the NHN may transmit an APN that indicates an NHN PLMN ID. From the APN, the UE may determine whether the NHN supports home-routed traffic. If the NHN supports home-routed traffic, the UE may transmit a packet data network (PDN) connectivity request to the NHN. If the NHN does not support home-routed traffic, the UE may establish a tunnel to the MNO network through Internet access provided by the NHN.

Abstract: Methods, systems, and devices are described for assessing the quality of end-to-end connectivity for a wireless communication device. Data generated from at least one of existing traffic and networking operations caused by existing traffic of the wireless communication device may be monitored to obtain information related to connectivity quality. One or more values of one or more metrics may be determined using the obtained information. The quality of end-to-end connectivity for the wireless communication device may be assessed using the value(s) of the metric(s). Based at least in part on a result of the assessment, an action may be performed to improve connectivity quality for the wireless communication.

Abstract: Various features pertain to the authentication of mobile devices or other User Equipment. In some aspects, a Retail-based Neutral Host LTE is provided for use with Long Term Evolution (LTE) networks that, among other features, provides a WiFi Alliance HotSpot 2.0 (HS2.0) user experience using LTE technology for non-mobile network operator (non-MNO) Service Providers (SPs), while maintaining high security assurances as with LTE. That is, in some examples, Retail Neutral Host-LTE is configured to provide the same or similar security assurances as with MNO-based LTE. Moreover, retail Neutral Host-LTE offers options for provisioning credentials and authentication with the AAA that are analogous to the options for HS2.0, that is: username/password, SP-issued certificate, and pre-configured mobile device certificate. This is achieved, at least in part, while providing or ensuring that Retail Neutral Host-LTE security provides similar security assurances to MNO-based LTE.

Abstract: A door edge protector device includes a protector, a cam member and a link mechanism. Cam portions are formed in the cam member, and the cam member is rotated by an input corresponding to a close/open state of a door. The link mechanism includes cam followers which are engaged with the cam portions, and the protector is attached to the link mechanism. By the engagement between the cam portions and the cam followers, the link mechanism moves in an interlocking manner with rotation of the cam member. A locus T includes an accommodated position corresponding to the close state of the door and a set position covering a door edge corresponding to the close state of the door. The cam portions are configured so that the protector moves along the locus by movement of the link mechanism.

Abstract: The disclosure provides for a user equipment (UE) to change from a first network to a second network for an internet protocol (IP) multimedia subsystem (IMS) call. Initially, the UE has a connection to a first network providing an IP address for the UE. The UE may receive, via the first network, a message indicating an incoming IMS call. The UE may transmit one or more IMS call setup messages on the first network at an IP layer. The UE may change the connection from the first network to a second network that uses a same identifier for the UE (e.g., the IP address). The UE may complete setup of the IMS call on the second network using the same identifier for the UE.

Abstract: A plurality of neutral host network (NHN) deployments may share a common evolved packet core (EPC). When a plurality of NHNs share a common EPC, continuity and mobility may be facilitated for a user equipment (UE) when the UE moves between NHNs (e.g., because the NHNs share a common EPC). Accordingly, a UE may perform a tracking area update (TAU) procedure when moving between NHNs that share a common EPC. However, a UE may need to discover whether two NHNs share a common EPC in order to perform a TAU procedure. If the UE discovers that, when moving between a first NHN and a second NHN, the NHNs do not sure a common EPC, the UE may perform an attach procedure.
