  • Patent number: 7620398
    Abstract: A method and apparatus is provided for simultaneously accessing a broadcast channel which allows for maintaining registration on the broadcast channel and a second channel. The broadcast channel includes a reverse link access channel for a portable communication device (120) to send registration messages to a base station and the method initially includes the step of determining whether a predetermined event requiring registration of the portable communication device on the broadcast channel has been detected (302, 304, 306). After detecting the predetermined event, it is determined whether the portable communication device is communicating on the second channel (308). If not communicating on the second channel (308), registration on the broadcast channel is accomplished by transmitting a registration message on the reverse link access channel (320).

  • Patent number: 7433331
    Abstract: A circuit (2) and method employing logic circuitry (30) and memory (40) identifies a reverse link limited channel (80). The logic circuitry (30) identifies a reverse link limited channel based on determining that an access probe failure occurred on a channel (64). The logic circuitry (30) causes the memory to store reverse link limited channel data (80) in response to the logic circuitry (30) determining that the access probe failure occurred. The reverse link limited channel data (80), for example, may be a channel identification associated with the channel (64), a base station identification associated with the channel (64), a location identification of the circuit (2) or any data suitable for identifying and adapting dynamically to the reverse link limited channel.

  • Publication number: 20080103686
    Abstract: An apparatus and method for route navigation for multiple destinations. Route parameters can be received and a route (140, 142) can be generated for multiple destinations (132, 134). An estimated time of arrival can be calculated for each destination. An updated estimated time of arrival can be generated for one of the destinations. A messaging service message including the updated time of arrival can be sent to a recipient (122, 124) associated with the respective destination if the updated time of arrival deviates from the original estimated time of arrival.

  • Publication number: 20080090587
    Abstract: In a method of configuring a mobile communication between a position determination entity and a mobile device, an indication that the mobile device has an ability to perform a positioning system search simultaneously with a communication is sent to the position determination entity. A preferred response quality indicator is set to a state that will allow the mobile device an extended period to provide to a location of the mobile device to the position determination entity when the mobile device has the ability to perform a positioning system search simultaneously with a communication.

  • Patent number: 7239396
    Abstract: This invention relates to a method and apparatus for measuring the phase change of an output optical signal from a device. In one embodiment an input optical signal is split into first and second optical signals, and the first optical signal is passed through the device while applying an external stimulus to the device, to produce an output optical signal having a phase shift. The carrier frequency of the second optical signal is changed, and the output optical signal and the changed second optical signal are then combined. The combined signal is detected in accordance with the external stimulus applied to the device, and the phase change of the output signal of the device is measured as a function of the external stimulus applied to the device.

  • Patent number: 7209742
    Abstract: Methods in communications devices and networks for reducing an infrastructure registration race condition. In one embodiment, a communications device transmits (310) a first network connection request is a first network, and after waiting a specified time interval, the communication device transmits (320) another network connection request to the first network. The communications device may determine the time interval, or it may be received (302) from the network. Alternatively, a time stamp or some other indicium is applied to the connection requests transmitted by the communications device so that a home location register or other entity may determine the order in which the requests were transmitted.

  • Patent number: 7181170
    Abstract: An apparatus and method for adaptive broadcast transmission. A broadcast transmission can be received. Insufficiency of a broadcast channel quality can be determined. A negative acknowledgement signal can be sent on a common uplink channel in response to determining the broadcast channel quality is insufficient. The negative acknowledgement signal can be received on the common uplink channel at another location, the negative acknowledgement signal indicating broadcast channel quality is insufficient. The broadcast channel quality can be adjusted in response to receiving the negative acknowledgement signal.

  • Patent number: 6160799
    Abstract: An apparatus (100) maintains a Pilot Set in a digital communication system that utilizes Code Division Multiple Access. The apparatus comprises a logic and control circuit (113) for providing instructions to a searcher receiver (109). The searcher receiver, in response to the instructions, sequentially scans active pilots, then candidate pilots, and then pre-candidate pilots. The scan of the pre-candidate pilots continues until all but a predetermined number of pre-candidate pilots have been promoted or demoted. Then the searcher receiver alternately scans the predetermined number of pre-candidate pilots and the neighbor pilots. The searcher receiver terminates alternate scans of the predetermined number of pre-candidate pilots and the neighbor pilots when a one of the neighbor pilots is promoted, and resumes the scan of the pre-candidate pilots.

  • Patent number: 5889768
    Abstract: A wireless communication device 100 acquires a pilot channel before an assigned slot when the wireless communication device is operating in the slotted mode of a CDMA system. The wireless communication device comprises a searcher receiver 107 that determines the short-term average pilot strength of active and neighbor pilot channels. Finger receivers 107 determine the long-term average pilot strength of the active and neighbor pilot channels. A logic and control circuit 113 assigns the finger receivers to the pilot channels according to their short-term average pilot strength, determines if the long-term average pilot strength of a neighbor channel is greater than the active pilot channel's pilot strength, and determines to hand off to the neighbor pilot channel with the greater long-term average pilot strength. Moreover, an early detection correlation length can be dynamically adjusted according to the pilot strength of the active pilot channel to shorten the pilot acquisition process.
