  • Publication number: 20140370830
    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 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.

  • Publication number: 20140248862
    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.

  • Publication number: 20140057598
    Abstract: Devices and methods are provided for automating client node access of a wireless network access node. A client node comprises a database containing identification data and access procedure data associated with a plurality of wireless network access nodes and credentials data associated with the client node. The client node receives identification data associated with a wireless network access node. The client node then processes the identification data to locate access procedure data in the database corresponding to the wireless network access node. Once identified, the client node then uses the access procedure data to provide its credential data to the wireless network access node. In response, the wireless network access node processes the credential data for approval, and once it is approved, grants the client node access.

  • Patent number: 8305897
    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.
