  • Patent number: 10251146
    Abstract: A method for registration-less paging includes establishing a mobile device identity for a mobile device in a wireless network, determining a time instance for the identified mobile device to listen to pages, and sending a page from the wireless network to the identified mobile device during the determined time instance. In one example, the method is for a network-initiated attach procedure and includes receiving a request to attach a mobile device in a wireless network, generating a paging message based on the request to attach the mobile device, sending a paging indicator to a mobile device based on the paging message during a time instance based on an agreed rule, and accepting an attach procedure from the mobile device based on the paging indicator.

  • Patent number: 9264868
    Abstract: Methods, systems, and devices are described for intercepting requests from applications installed on a mobile device. The requests are system calls that establish communication channels for the mobile device. The requests are captured and held from reaching TCP/IP stack of an operating system executing on the mobile device. An intercepted request is aggregated with other intercepted requests. The aggregated requests are bundled together and released to the operating system upon the detection of a triggering event. The capture, holding, and aggregation of requests from applications occur when the mobile device is in a background mode.

  • Patent number: 9143230
    Abstract: Various exemplary methods and apparatus are directed to using Visible Light Communication (VLC) in a downlink, e.g., a supplemental downlink, in combination with a wireless radio downlink/uplink pair. A gateway is coupled, via a wireline link, to a VLC access point. In some embodiments, the gateway includes a wireless radio base station. A user equipment device detects a visible light signal from the VLC access point, and transmits a radio signal to a communications device, e.g., a gateway including a base station or a macro base station, indicating that the UE device is in a VLC coverage area. The gateway configures the VLC access point to serve as a supplemental wireless cell which supports downlink communications. The gateway sends traffic signals to the VLC access point, via the wireline, which are converted by the VLC access point into VLC signals which are transmitted. The UE device receives VLC downlink traffic signals and transmits a corresponding acknowledgment signal via an uplink radio channel.

  • Patent number: 9049629
    Abstract: Systems and methodologies are described that facilitate inter-system handover in a wireless communication system. Various aspects described herein provide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes required to source system and/or target system. Techniques are described herein in which the radio link of a source system can be utilized to tunnel signaling messages which are in a format understood by a destination node in a target system. Further, fast inter-access handover can be facilitated by establishing a simple generic transmission tunnel between respective network nodes in source and target systems that handle intra-system mobility and providing a Layer 2 (L2) tunneling mechanism over the radio interface of each involved system technology.

  • 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.

  • Patent number: 8913537
    Abstract: A control scheme using packet headers allows GSM EDGE Radio Access Network (GERAN) systems to increase spectral efficiency through multiplexing techniques, such as superposition coding, multi-user packet transmission, joint detection, and/or joint decoding. A fast feedback scheme for GERAN allows Voice over Internet Protocol (VoIP) frames to be transmitted over GERAN air interfaces without excessive feedback latency. As a result, Hybrid Automatic Repeat-reQuest (H-ARQ) acknowledgements may be timely provided for end-to-end VoIP calls that traverse GERAN air interfaces. Additionally, Incremental Redundancy H-ARQ and link quality feedback latencies are decreased.

  • Patent number: 8804761
    Abstract: Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transitions that occur when the User Equipment (UE) moves from one cell to the other, or when the delivery of content changes from a Point-to-Point (PTP) connection to a Point-to-Multipoint (PTM) connection in the same serving cell, and vice-versa. Such transmission techniques enable seamless delivery of content across cell borders and/or between different transmission schemes such as Point-to-Multipoint (PTM) and Point-to-Point (PTP). Mechanisms for adjusting different streams and for recovering content from each data block during such transitions are also provided so that data is not lost during a transition. In addition, mechanisms for realigning data during decoding at a receiving terminal are also provided.

  • Patent number: 8787249
    Abstract: In a wireless communication system having multiple access nodes, a home agent (HA) maintains home address (HoA) for a mobile node so that an IP session can be established. As the mobile node moves within a coverage area of various access nodes, the mobile node can establish a secure relationship with a local access gateway and thereby register a local IP address, referred to as a care-of-address (CoA), with the HA. Mobile IP protocol can be established so that multiple sessions can be conducted. In maintaining policy and charging control (PCC), HA informs a policy and charging rules function (PCRF), which in turn can then send the appropriate PCC rules (e.g., IP flows and related policies) to a policy and charging enforcement function (PCEF) for a particular access gateway. Coordination necessary to associate CoA and HoA can further include filter information as to application can run on a particular interface.
