  • Patent number: 10349329
    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.

  • Patent number: 10341239
    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.

  • Patent number: 10327278
    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.

  • Patent number: 10277515
    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.

  • Patent number: 10244381
    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.

  • Patent number: 10243839
    Abstract: In aspects of the disclosure, a method, an apparatus, and a computer program product for wireless communication by a user equipment (UE) are provided. In one aspect, the UE associates with an access point of a wireless local area network which may be untrusted, obtains a list comprising a plurality of public land mobile network (PLMN) entries and one or more selection conditions associated with each one of the plurality of PLMN entries, and selects a PLMN from the list when the one or more selection conditions associated with the PLMN are satisfied. The UE may further discover an evolved packet data gateway (ePDG) for the selected PLMN using one or more fully qualified domain name (FQDN) rules for the selected PLMN. The UE may then attach to the selected PLMN using the discovered ePDG.

  • Patent number: 10237795
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication. A user equipment (UE) device may be connected to a first evolved packet data gateway (ePDG) via a first radio access technology (RAT). The UE may evaluate, either periodically or based on a trigger event, an ePDG reselection metric associated with the first ePDG to determine whether selecting a second ePDG different from the first ePDG is viable. The UE may then reselect to a second ePDG based on whether the ePDG reselection metric satisfies one or more selection conditions. Selection conditions may include, for example, a change in the location or public land mobile network (PLMN) of the UE, UE movement between networks, or a connection failure associated with the first ePDG.

  • Patent number: 10231250
    Abstract: Techniques are described herein to communicate policy information and policy information requests between user equipments (UEs) and a core network using control plane signaling. In some examples, non-access stratum (NAS) messages may be used to communicate policy information requests from a UE to the core network. Similarly, NAS messages may be used to communicate up-to-date policy information from the core network to the UE. In some examples, the core network may include number of functions to manage the communication of policy information with the UE. In some examples where the UE is roaming away from its home network, the core network may engage in additional signaling to pass policy information to the UE.

  • Publication number: 20190075076
    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 a network security gateway to provide network security and internet working control based on the FQDN.
