  • Patent number: 7688260
    Abstract: Method and apparatus for locating position of a mobile device in an assisted satellite positioning system is described. In one example, satellite measurement data is obtained from a plurality of satellites at a mobile device. Position of the mobile device is computed using the satellite measurement data. The position is sent to a cellular device via a wireless ad hoc network. In one example, the wireless ad hoc network comprises a BLUETOOTH communication link. In one example, the mobile device is configured to receive assistance data from a position server through the wireless ad hoc network. For example, the mobile device may comprise a housing configured to plug into a cigarette lighter connector of an automobile and the cellular device may comprise a cellular telephone without location-determination capabilities (i.e., the cellular telephone does not include an integrated GPS receiver).

  • Patent number: 7689234
    Abstract: A method and device for transmitting at least one short messaging service message to at least one wireless device are disclosed. The method comprises receiving at least one short message service message request associated with a short message service message. The short message service message is destined for reception by a wireless device (106). Prior to receiving the request, a short message service center (114) determines if a wireless device (106) is registered with a registrar (210) associated with a session initiation protocol network for communicating over a packet data network (102). The short message service message is transmitted to the wireless device (106) through the session initiation protocol network communicating over the packet data network (102) in response to the request and with the determination that the wireless device (106) is registered with the registrar (210).

  • Patent number: 7689227
    Abstract: Method and apparatus for hashing mobile stations to frequencies in a communication system. The method uses two-level hashing to assign a mobile station first to frequency band and then to a specific frequency within the frequency band. Embodiments allow for weights to be assigned to frequencies and mobiles hashed to the weighted frequencies. Weighting allows for a non-uniform distribution of mobile stations among frequencies to optimize system operating parameters.

  • Patent number: 7680500
    Abstract: An apparatus, system, and method efficiently manage reverse link communication in a communication system having geographically distributed base stations. A base station functioning to at least one mobile station as a non-serving active base station estimates an expected coupled load due to the at least one mobile based on a previous total coupled load. The base station determines a total available capacity based on the difference between the total capacity of the base station and the estimated expected coupled load. The base station allocates reverse link resources to other mobile stations served by the base station so as not to exceed the total available capacity. Since the allocation of reverse link channels resources are controlled directly by the base station, delays due to communications with a central controller are eliminated. As a result, adverse effects of load scheduling based on obsolete reverse channel information are minimized.

  • Patent number: 7675842
    Abstract: A process is described to build physical layer frames with a modcode adapted to the signal quality of a destination terminal. Data packets assigned to the same modcode may be sent in the same frame, although packets associated with higher modcodes may be used to complete a frame before switching to the applicable higher modcode for construction of subsequent frames. After an interval, the order of progression is restarted with an out of order packet above a threshold age. Flow control filtering mechanisms and a variable reliability margin may be used to adapt dynamically to the current data traffic conditions.

  • Patent number: 7668126
    Abstract: Each of a plurality of nodes in a wireless network is capable of generating, transmitting, and receiving beacons in a distribute fashion. Each beacon contains information regarding the order of which other nodes are to transmit beacons and wireless medium access information at to when various nodes are to access the network. Nodes that are in separate “extended neighborhoods” are permitted to transmit their beacons simultaneously without risking beacon collisions. The beacons contain information that is used to ensure this result. Using the distributed beacon mechanism, each nod can reserve access to the wireless medium. In the disclosed embodiments, a central coordinator is not needed.
