  • Patent number: 9838944
    Abstract: A wireless communication access path exists between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations directly or through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add information bearing on an identified QoS associated with the PDU to the PDUs before they are delivered to the downstream egress station(s) or intermediate relay station(s). The information may be used by the downstream stations to schedule the PDUs for further delivery. The information may also be used by the egress station to schedule the PDUs for delivery.

  • Patent number: 9426754
    Abstract: A system and method may dynamically control the total RF power emissions of a mobile device. The method may include determining the local RF operating situation of the mobile device; setting a maximum power limit according to the local RF operating situation; and/or adjusting an active transmitted power of the mobile device within the maximum power limit. The local RF operating situation may be determined based upon (1) the measuring of a matching of the mobile device's radio antenna(s); (2) currently active application(s); (3) the number/type of active radios; (4) frequency or wavelength of transmissions; (5) network, relay, or node RF operating or exposure conditions; and/or (6) a power control process. The mobile device may be a hand-held device, HomeNodeB, or other device capable of RF communications. The local RF operation situation and/or available headroom may be communicated to a network base station or node to facilitate enhanced mobile device performance.

  • Patent number: 9380642
    Abstract: A device and method are provided for concurrently using a plurality of radio access technologies (RATs) to support a wireless-enabled communications session. A set of data is processed at a client node to identify a subset of priority data. The set of data and the subset of priority data are respectively provided to a first and second protocol stack, which correspond to a first and second RAT. The first and second protocol stacks are then used to control the transmission of a first and second set of transmitted data, which in turn respectively comprise the set of data and the subset of priority data. The first and second sets of transmitted data are received by an access node, which uses corresponding first and second protocol stacks to control their reception. The first and second sets of transmitted data are then processed to generate a set of received data.

  • Patent number: 9325677
    Abstract: A telecommunications device is provided. The telecommunications device comprises a processor configured such that the device sends a first message to a database management component, the first message containing a communications key encrypted by a database management component key. The processor is further configured such that the device receives a second message from the database management component, the second message encrypted by the communications key. The processor is further configured such that, when the device is able to decrypt the second message, the device considers the database management component to be legitimate.

  • Patent number: 9237453
    Abstract: A spectrum channel sharing system may coordinate a shared usage of one or more spectrum channels between a first communication system and a second communication system. The first communication system may transmit a request to the second communication system to clear communication traffic associated with the second communication system from a spectrum channel. The first communication system may then initiate a communication session on the spectrum channel after the communication traffic associated with the second communication system has been at least partially cleared from the spectrum channel.

  • Patent number: 9143255
    Abstract: The present invention uses a portion of an orthogonal spreading code space in a CDMA spectrum for uplink from a user element to a base station. By assigning the user elements one or more codes, which are orthogonal to those used to spread data, to use for uplink , the present invention significantly reduces interference between channels, and between the data channels and the channels, while supporting additional capacity. The codes may be individually assigned to user elements or assigned to groups of user elements. Further, different length codes may be assigned to the user elements to support different rates depending on Quality of Service (QoS) requirements.

  • Patent number: 9084235
    Abstract: Devices and methods are provided for determining the proximity of client nodes within a wireless-enabled communication environment. A first client node comprises a database containing identification data associated with a plurality of wireless network access nodes and fingerprint data associated with the client node and a plurality of second client nodes. As the fingerprint information is updated, it is processed by the first client node to identify second client nodes that have matching, or similar, fingerprint information. Those that do are determined to be within a viable device-to-device (D2D) communication range.

  • Patent number: 9071987
    Abstract: A method of establishing communication links during a failure within a mobile communications network includes detecting disruptions in communications between a plurality of base stations and a plurality of mobile terminals. Survivability components are activated within the base station and the mobile terminal to operate in a survivability mode. The survivability mode enables communications and services to be provided by the surviving base stations to mobile terminals through activated survivability components. The alternate communication links may operate for as long as a disruption exists.

  • Patent number: 8958300
    Abstract: One or more relay stations may be employed along a wireless communication access path between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add scheduling information to the PDUs before they are delivered to the downstream intermediate relay stations or egress stations. The scheduling information is used by the downstream stations to schedule the PDUs for further delivery. The scheduling information may also be used by the egress station to schedule the PDUs for delivery. The scheduling information added to the PDU by the ingress station bears on a QoS class associated with the PDU, a deadline for the egress station to deliver the PDU, or a combination thereof.
