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: Communication using a radio access network (RAN) including a primary cell for license spectrum access and a secondary cell for unlicensed spectrum access may be improved to provide optimal performance while considering characteristics of the primary cell and the secondary cell. The apparatus may be a core network entity. The core network entity is connected to a RAN including a primary cell utilizing a licensed spectrum and a secondary cell utilizing an unlicensed spectrum. The core network entity determines an authorization for data traffic to be offloaded to the secondary cell based on data traffic characteristics. The core network transmits an indication of the authorization to the RAN.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device transmits an indication of whether the device should be paged over a 3GPP access when a core network has data ready to transmit for PDU sessions over a non-3GPP access. A session management function (SMF) of the core network receives a data notification indicating that the core network has data ready to transmit to the wireless device for a PDU session over the non-3GPP access. The SMF determines whether to transmit a paging request to an access and mobility management function (AMF) of the core network based on a paging state of the SMG, a paging state of the wireless device, or a connection management idleness state of the wireless device. The AMF determines whether to transmit a paging message to the wireless device.

Abstract: Methods, systems, and devices are described for decreasing user plane latency in a wireless communication system. This may include routing a portion of bearer traffic to or from a UE through a local or serving gateway, or within or between base stations, rather than via the core network. In some examples, techniques for selected internet protocol flow ultra-low latency (SIPFULL) for systems in which users may have subscribed to enhanced services may be employed. The network may, for instance, authorize SIPFULL functionalities for UEs per access point name (APN) based on individual services subscribed by the UE to improve overall quality of service (QoS). In some examples, a UEs latency requirements or SIPFULL authorizations may affect mobility operations.

If the communication is delayed, the user equipment performs discontinuous reception to save power until the communication is available. If the communication is unavailable, the user equipment resumes a sleep mode.

Abstract: Techniques are provided for transmission of small data packets through a paging procedure in a MTC or cellular internet of things system (CIoT). A core network may receive data to be transmitted to a user equipment (UE) and may determine that a small data packet transmission may be initiated for the data. The core network may format the small data packet into a paging request that includes the data and a UE identification, and transmit the paging request to a base station. The base station may receive the paging request, and initiate a page process with the UE. The UE may receive a page message, and initiate an access procedure that may be used for transmission of the small data. The UE may be in idle mode prior to the small data transmission, and in some examples may return to idle mode following the transmission of the small data.

Abstract: Neutral host networks may offer one or more different services via one or more different service providers, but user equipment (UE) may not necessarily know which services/service providers are offered by the neutral host networks. Accordingly, nodes of the neutral host networks (e.g., an access point, such as an evolved Node B (eNB)) may transmit service discovery information (SDI) to advertise the one or more services or service providers offered by the node and/or the neutral host network. Thus, a UE can receive the SDI via broadcast by the node, dedicated message from the node, etc., and can accordingly present at least a portion of the SDI or determine whether to connect to the node or another node of the neutral host network based at least in part on the SDI.

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.
