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.

Signal strength indication methods for use in wireless communication devices

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. The proximity application server can correlate the proximity data signal. Correlated data in turn may be sent back to a receiving device of the enterprise.

Systems and method for triggering proximity detection

A method and apparatus provide for soft handoff operation of at least a first signal transmitted according to a first communication standard (IS-95B) and a second signal transmitted according to a second communication standard (IS-95C). A mobile station () initially receives the first signal, detects presence of a pilot signal, measures pilot signal strength, transmits a pilot strength measurement message, fails to receive a handoff direction message after transmitting the pilot strength measurement message, searches for detecting presence of a broadcast control channel associated with the type IS-95C cell sites, measures a carrier to interference ratio of the broadcast control channel, compares the carrier to interference ratio to a threshold, if the carrier to interference ratio is above the threshold, initiates a second communication according to IS-95C standard, thus, allowing initiating a soft handoff operation by allowing the base sites to transmit information according to the IS-95B and IS-95C standards respectively via the first and second signals. MScombines the first and second signals to take advantage of the soft hand-off operation.

Method and apparatus for soft handoff communications in a communication system operating according to IS-95B and IS-95C standards

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.
