Abstract: A radio frequency (RF) coverage server for use in a wireless network comprising base stations that communicate with mobile stations located in a coverage area of the wireless network. The RF coverage server receives from the mobile stations geographic location data indicating positions of the mobile stations when communication links to the wireless network were dropped. The RF coverage server identifies areas of good RF coverage and areas of poor RF coverage in the wireless network. The RF coverage server also identifies a first one of the mobile stations that frequently drops communication links to the wireless network when the first mobile station is disposed in the good RF coverage areas.

Abstract: A variable bandwidth controller for use in a wireless network comprising base stations capable of operating on N carriers. The variable bandwidth controller determines a receiver capability of a first mobile station and, in response to the determination, assigns the first mobile station to operate on at least a first carrier and a second carrier. The variable bandwidth controller determines the receiver capability of the first mobile station based on a message received from the first mobile station. The variable bandwidth controller assigns the mobile station to operate on the first carrier during normal data traffic conditions and assigns the mobile station to operate on the second carrier during peak data traffic conditions.

Abstract: Beam-formed transmission from a transmitting wireless communication station to a receiving wireless communication station is supported by estimating a direction for the beamformed transmission. The receiving station reports to the transmitting station information about wide-beam and narrow-beam pilot signals that the receiving station has received from the transmitting station. The transmitting station estimates the direction of the beamformed transmission based on this information.

Abstract: There is disclosed a system and method wherein signals generated by a mobile station and received at multiple base transceiver stations (BTSs), are combined utilizing signal processing techniques. Signals received at non-target BTSs are directed, by each non-target BTS, to a target BTS where a combiner is utilized to assemble the received signals (bits) into a packet, or frame, and to determine if an error condition exists. The error condition of the frame or packet determines whether to utilize BTS power control circuitry to notify the mobile station to adjust the mobile station transmit power up or down.

The base station is divided into a main unit and a radio unit such that the radio unit is positioned proximate to the antennas and the main unit is remotely located from the radio unit. A single base station transceiver can provide service via multiple wireless protocols, such as CDMA, TDMA, GSM or Analog. The base station transceiver .can also operate on various transmit/receive frequencies as well as variable transmit power settings. Furthermore, the base station transceiver can be reprogrammed, reconfigured and/or statused by a network operations center.

Abstract: Two radio systems are provided for each coverage area within a wireless communications system, each radio system supporting a different wireless communications standard with at least one of the standards being compatible with the other (such as the backward-compatibility of either of 1xEV-DO or 1xEV-DV with IS-2000). Both of the radio systems may have a sectored configuration for selected coverage areas while a combination of sectored and omni configurations are employed for the radio systems for other coverage areas. When communications with a mobile station utilizing one standard fails within a coverage area due to antenna, radio frequency path, or radio system failure, wireless communications with that mobile station is automatically resumed utilizing the other, compatible wireless communications standard.

Abstract: A wireless communication system (200, 300, 400, 500) mitigates the effects of excess timing delay caused by varying lengths of communication paths. In one general implementation, a transition communication path (206, 323, 329) is used to transfer a time-advanced version of a timing reference signal so that the cumulative time delay at a transition cell (209, 325, 331) is reduced. In another general implementation, the timing reference signal is time-advanced in all communication paths (403-411), and selected communication paths (403-407) include a time delay means (423-427, 503-507) such that the cumulative time delay at an area (421) near a target coverage area (130) is reduced. By reducing the cumulative time delay at the area (421) near the target coverage area (130), a handoff of a communication of a mobile station (128) into the target coverage area (130) can be performed.

Abstract: A secretarial telephone station for use with a secretarial answering system and a switching system which includes a plurality of subscriber telephone stations each equipped with a buzzer. The secretarial answering system is connected to the subscriber stations and transmits subscriber station busy, idle and ringing status and line identification information to the secretarial station. The secretarial station includes a lamp and switch pair for each associated subscriber station, first and second processing units, and an audible signalling circuit. The first processing unit receives this information according to a link bus protocol for packetized messages. The second processing unit receives this information and causes the lamp associated with each of the subscriber stations to display dark, lit or flashing signals corresponding to the idle, busy and ringing status. The second processing unit also causes the audible signalling circuit to provide a ringing tone whenever a lamp is flashed.
