  • Patent number: 9521644
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a target UE, an initiator UE, or an MME. In one configuration, the apparatus is an initiator UE. The initiator UE determines a network address of a target UE based on a target expression, sends a connection request including information associated with the initiator UE to the target UE at the determined network address, sends information associated with the target UE to an MME serving the initiator UE, and receives, from the MME serving the initiator UE, one or more parameters for communicating with the target UE. Further, the initiator UE communicates with the target UE based on the one or more parameters.

  • Publication number: 20160254993
    Abstract: Systems and methods are described that facilitate multiple registrations and flow based mobility in a wireless communication network. A flow routing component can be included in a mobile device, home agent/p-gateway, or a policy and charging rules function server that determines the manner in which to route one or more IP flows through a set of network access entry points. The flow routing component can determine the routing based on a set of policies and/or network data, such as quality of service requirements, bandwidth requirements, network congestion, currently active IP flows, and so forth.

  • Publication number: 20160212632
    Abstract: The disclosure generally relates to avoiding physical cell identifier (PCI) collision and confusion using LTE-Direct expressions. In particular, a small cell may discover LTE-Direct expressions that include PCIs associated with neighbor small cells and select (or reselect) a local PCI to ensure that the local PCI differs from the PCIs associated with each neighbor small cell. Furthermore, the small cell may detect PCI confusion where multiple neighbors broadcast LTE-Direct expressions with the same PCI and different E-UTRAN Cell Global Identifiers (eCGIs) and/or detect PCI confusion in neighbor small cells where the local PCI matches the PCI used in a neighbor's neighbor and the local eCGI used in the small differs from that used in the neighbor's neighbor. The small cell may additionally broadcast LTE-Direct expressions that include at least the local PCI and eCGI to enable neighbors to avoid PCI collision and confusion in the same manner.

  • Patent number: 9351145
    Abstract: Systems and methodologies are described that facilitate Mobile IP home agent (HA) discovery in a wireless communication system. Discovery of a HA for Mobile IP can be conducted as described herein for a mobile terminal located on a network wherein movement of the terminal is managed by a network-based mobility protocol. For example, various aspects described herein can be utilized for discovery of a HA located in a 3GPP network from 3GPP and/or non-3GPP access. Further, various aspects described herein can be utilized to discover a gateway acting as mobility anchor for a network mobility protocol utilized by the network. As additionally described herein, HA discovery can be conducted in connection with DNS query formation and communication, network attach and/or re-attach procedures, Neighbor Discovery signaling, and/or other procedures.

  • Patent number: 9179305
    Abstract: Aspects describe enabling two peers that have already paired together under some circumstances to re-identify themselves under different circumstances so that the peers can bypass performing another pairing only to discover that they are already paired. A Bloom filter is constructed from an available pool of locally selected identifiers and is sent to a peer node in a first message. Upon receiving the message with the Bloom filter, peer node checks all its known identifiers. If peer node finds that one of its identifiers is a member of the Bloom filter, peer node sends a reply in order to achieve a mutual identification.

  • Patent number: 9049645
    Abstract: Methods and apparatus for improved monitoring and tracking of communications devices, e.g., peer to peer devices, using assistance from WAN elements such as base stations, are described. In some embodiments, a wireless terminal requests peer to peer communications discovery assistance from one or more base stations. In some embodiments, the request includes information identifying peer communications discovery information the wireless terminal is seeking to detect. In some embodiments, upon receiving the request, nearby base stations listen to the common discovery channel and upon detecting the specified discovery information, send a response indicating the detection of the discovery information and a proximate location of the announcing peer device, to the wireless terminal. The wireless terminal can use the received information to locate and page the announcing peer via the base station serving the announcing peer.

  • Patent number: 9043862
    Abstract: Systems and methodologies are described that facilitate communicating encapsulation information for a related mobility protocol type utilized in communicating over a data flow with reduced specific implementation on the policy server to support different mobility protocol types. In this regard, encapsulation information can be transmitted to the policy server from a network gateway such that the policy server can forward the encapsulation information to a serving gateway along with policy rules related to a data flow type. The serving gateway can utilize the encapsulation information to detect and interpret the encapsulated data flow according to the policy rules. In this regard, the serving gateway can provide support (e.g., quality of service support) for the flow. The encapsulation information can relate to a mobility protocol type, an encapsulation header, an indication that encapsulation is required, parameters regarding locating an encapsulation header in a message, and/or the like.

  • Publication number: 20150043446
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a priority for performing a wide area network (WAN) operation or a device-to-device (D2D) operation using a downlink receive chain, and performs the WAN operation or the D2D operation using the downlink receive chain according to the priority. In another aspect, the apparatus determines downlink resources on which a WAN operation is performed, refrains from scheduling the WAN operation on the downlink resources when the WAN operation is not scheduled or expected to be scheduled on the downlink resources, and sends to a device priority information indicating a priority for the device to perform the WAN operation or the D2D operation using a downlink receive chain when the WAN operation is scheduled or expected to be scheduled on the downlink resources.

  • Publication number: 20150030003
    Abstract: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.

  • Publication number: 20150029893
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives information from a serving base station and at least one neighboring base station. The information indicates a time allocation of discovery resources allocated by each of the serving base station and the at least one neighboring base station for performing direct discovery. The apparatus further determines a subframe timing of the serving base station and the at least one neighboring base station, and performs direct discovery using the time allocation of the discovery resources allocated by each of the serving base station and the at least one neighboring base station based on a determined subframe timing of the serving base station or a neighboring base station corresponding to the discovery resources.
