  • Patent number: 8825109
    Abstract: Communication devices capable of at least two communication modes (e.g. WLAN, WMAN and WWAN and/or wired modes) can be configured to optimize communications using a policy-based mechanism to configure connections and routes. A rules engine evaluates its policies on a state change (e.g. network availability, time of day, etc.) to configure a routing table and, together with communication APIs, provides an appropriate connection to an application for its respective communications. Policies may be responsive to various factors such as Radio Access Technology (high/low bandwidth), cost, presence, time of day, location, application type and quality of service (QoS) requirements among others to optimize communications.

  • Patent number: 8687608
    Abstract: Techniques for extending coverage of a wireless communication network (e.g., a cellular network) to indoor and other locations are described. A wireless device may communicate with a base station in a wireless network via downlink and uplink frequency channels in a licensed frequency band using frequency division duplexing (FDD). The wireless device may communicate with a piconet base station (PBS) in a pico network (piconet) via the uplink frequency channel using time division duplexing (TDD). The PBS may communicate with the wireless device on the uplink frequency channel and may exchange data with the wireless network via a wireline communication link. The PBS may forward data received from the wireless device to the wireless network and may also forward data received from the wireless network for the wireless device to the wireless device. The PBS may receive paging messages from the wireless network for the wireless device and may forward the paging messages to the wireless device.

  • Patent number: 8666434
    Abstract: A location of a network user computing device is determined relative to a location of a point of interest. If the user device is determined to be stationary, the user device is monitored for movement, the movement resulting in re-determining the location of the user device relative to a location of the point of interest. If the user device is determined to be moving, the velocity of the user device is matched with a predetermined velocity, and a preliminary estimated time of arrival to the point of interest is determined based on the predetermined velocity matched to the user device. At a later time that is based on a function of the preliminary estimated time of arrival, an estimated time of arrival to the point of interest is verified based on the predetermined velocity matched to the user device.

  • Patent number: 8625482
    Abstract: The traffic of wireless communication between wireless access points can be lowered without requiring a change in the access point to which an associated station belongs, to thereby efficiently use a band for the wireless communication. For this purpose, (1) a station sends a packet, and a wireless access point and a wired access point receives the packet; (2) the wired access point stores an identifier indicating proxy transmission in an ACK packet and then transmits the ACK packet, and (3) the wireless access point confirms the proxy processing identifier of the ACK packet from wired access point and stops delivery of packets to the backhaul. The wired access point delivers the packet to a destination of the packet.

  • Patent number: 8626154
    Abstract: In one aspect, an exemplary method involves a WCD: (i) determining a likelihood of roaming, wherein the likelihood of roaming indicates a likelihood that the WCD will be handed off from a preferred coverage area to a non-preferred coverage area; and (ii) using the likelihood of roaming as a basis for managing an active set of the WCD. In particular, the WCD may manage its active set by setting at least one active-set parameter affecting the number of active sectors in an active set of the WCD, and then maintaining its active set according to the setting of the at least one active-set parameter. According to an exemplary embodiment, a WCD will make an effort to increase the number of sectors in its active set when the likelihood of roaming is greater, and vice versa.

  • Patent number: 8588777
    Abstract: A communication system that allows a soft handoff to be completed, even when the communications link between the active base station and the mobile station deteriorates before the mobile station has received the handoff direction message. The mobile station maintains a list of base stations that the mobile station is in communication with, referred to as an “Active Set”. In addition, the mobile station maintains another list of base stations that are proximate to the base stations in the active set. This list is referred to as the “Neighbor Set”. In accordance with the disclosed method and apparatus, the mobile station places a base station in the active set upon including the base station in a pilot strength measurement message (PSMM). The mobile station monitors transmissions from all of the base stations on the active set to receive a handoff direction message (HDM).

  • Patent number: 8509800
    Abstract: Systems and methods are provided for adaptive control of call quality-of-service. Using the systems and methods, if the uplink of a given mobile station is congested, the quality of the data, e.g., video data, sent by the mobile station along its uplink is adjusted to allow an optimal number of calls to be transmitted through the congested location. A centralized base station controller (CBSC) may obtain congestion information, such as frame loss ratio or frame delay, from its portion of the mobile network. The CBSC then relays this information to a mobile station and/or to a CBSC associated with one or more mobile station(s) at the other end of the call. The mobile stations may then adapt the quality of the video conferencing accordingly. Using the disclosed systems and methods, bandwidth utilization may be improved, allowing a high number of calls to be completed, and reducing the occurrence of dropped calls.
