  • Patent number: 8744391
    Abstract: Embodiments include signal strength indication methods for use in wireless communication devices. In an embodiment, a method includes producing a default received signal strength indicator (RSSI) using default RSSI determination parameters. The method also includes determining that a received signal strength is inadequate, and producing an alternate RSSI, in response, where the alternate RSSI is produced using at least one alternate RSSI determination parameter that is different from at least one default RSSI determination parameter. In another embodiment, a method includes measuring multiple received signal strengths for multiple received signals from multiple base stations, and producing an alternate RSSI based on a received signal strength measurement for a strongest signal of the multiple received signals. An embodiment of a wireless communication device may include a processing subsystem adapted to perform embodiments of the methods.

  • Patent number: 8204477
    Abstract: Disclosed are methods and devices including a mobile communication device, a proximity application server and a receiving device. The methods of the mobile communication device include receiving an enterprise identification signal that may be an SSID transmitted by an enterprise access point. The user of the mobile communication device may have opted into receiving the services of the enterprise in accordance with the disclosed methods and devices. Therefore, the mobile communication device may generate a proximity data signal including an indication of receipt of the enterprise identification signal and an identifier of the mobile communication device. The identifier may be the telephone number of the mobile communication device. The mobile communication device can then transmit the proximity data signal to a proximity application server.

  • Patent number: 7242955
    Abstract: A method, apparatus and system are provided for use in better optimizing switched beam, wireless communications. In some embodiments, a method is provided that receives a communication over a first wireless reverse link beam, selects a type of beam weighting control, determines a rule according to the type of beam weighting control, and determining a weighting of a forward link beam according to the rule. The method can further determine an energy of the first reverse link beam, and determine a first gain energy ratio based on the first reverse link beam energy, such that the weighting is determined by applying the first gain energy ratio to the rule. Some embodiments further determine a pilot beam configuration, wherein the rule is determined according to the pilot beam configuration and the selected type of beam weighting control.

  • Patent number: 6754193
    Abstract: A method (700) and a base station controller (120) for operating in accordance with a wireless communication protocol are described herein. In a wireless communication system (100), the base station controller (120) may detect that the mobile station (160) is operable in accordance with the wireless communication protocol based on information associated with the mobile station. In response to detecting at least one of condition of the system (100) suggesting a potential for improved system performance, the base station controller (120) may transmit a handoff message from the first base station (140) to the mobile station (160). The handoff message may notify the mobile station (160) to operate in accordance with the wireless communication protocol.

  • Patent number: 5999815
    Abstract: The present invention provides a method for implementing diversity for a dual-mode communication unit in a communication system. The communication system includes a first transceiver utilizing a first air interface and a second transceiver utilizing a second air interface distinct from the first air interface. The system also includes a controller that includes a selector function. The dual-mode communication unit transmits a first copy of bearer data to the first transceiver utilizing the first air interface. The dual-mode communication unit transmits a second copy of the bearer data to the second transceiver utilizing the second air interface. The first transceiver and the second transceiver sending the copy of the bearer data to the controller. The first transceiver and the second transceiver also send a quality metric to the controller. The controller selects a preferred copy of the bearer data based at least in part upon the quality metrics.

  • Patent number: 5901354
    Abstract: Generally stated, a method for performing soft-handoff within a wireless communication system 100 is described herein. The wireless communication system 100 includes, inter alia, a mobile station 104, a first base station 102 in communication with said mobile station via a first communication resource 120, and a second base station 106 with a corresponding second communication resource 130. In a first preferred embodiment, a determination is made that the first communication resource 120 is no longer necessary. The wireless communication system 100 verifies that the second base station 106 has acquired the mobile station 104 via the second communication resource 130. If the second base station 106 has yet to acquire the mobile station 104 on the second communication resource 130, the wireless communication system 100 will override the normal power control mechanisms, increasing the mobile station's 104 transmit power, thereby mitigating the opportunity for an orphan condition to develop.
