Abstract: The invention can provide a movable wireless network that is capable of operating in a multiple network environment. The movable wireless network has a coverage area and includes a detector that detects a network event when the coverage area of the movable wireless network overlaps with a coverage area of another wireless network. The invention can further include a controller that changes an operational state of the movable wireless network when the detector detects the network event so that the movable wireless network is able to operate within the coverage area of the other wireless network.

Abstract: A remote unit for a personal wireless area network includes a receiver, an AC power supply, a battery-backup power supply and a controller. The battery-backup becomes operative when the AC power supply fails and supplied power to the receiver. The controller detects when the AC power supply fails and controls the receiver and the battery-backup power supply by invoking a sleep mode of operation. The sleep mode of operation is periodically interrupted by the controller controlling the receiver and the battery-backup power supply to enter a standby mode of operation in which the receiver scans for a CONNECT message from a base station indicating an incoming call. The controller coordinates the sleep mode and the standby mode of operations based on a frame count that is generated from an identification number of the remote unit.

Abstract: Improved communication service methods operate in conjunction with a wireless communications network that includes a plurality of cells, microcells, and/or picocells. A user zone is defined as including one or more cells, microcells, picocells, and/or one or more cell, microcell, and/or picocell sectors. A first set of communication features are provided within the user zone, and a second set of communication features are provided outside the user zone. According to an embodiment disclosed herein, a mobile telephone switching office (MTSO), coupled to the user zone, stores a user zone profile identifying the cells, picocells, microcells, picocell sectors, microcell sectors, and cell sectors included in the user zone. The MTSO selectively modifies a service profile for a cellular telephone if (I) that cellular telephone is situated within the user zone, and optionally (ii) that cellular telephone is authorized for that user zone.

Abstract: A mobile station communicates with both a cellular network, by which it is assigned a mobile identification number, and to a cordless cellular base station utilizing the same cellular frequency range and communications protocol. The cordless cellular base station is preferably connected to a public switched telephone network and is assigned a landline number. The cordless cellular base station acts as a conduit between the mobile station and the public switched telephone network. When the mobile station comes within range of a cordless cellular base station, it deregisters automatically from the cellular network and register with the cordless cellular base station. Once the mobile station is communicating with the cordless cellular base station, the cordless cellular base station communicates with the cellular network to instruct the cellular network to route all calls for mobile identification number to the cordless cellular base station's landline number.

Abstract: In a discrete tone system, a base station receives a transmission burst from a remote unit being installed that includes delay compensation pilot tones that are uniformly spread throughout the transmission bandwidth. The arrival time transmission burst is not synchronized with the other remote units transmitting to the base station. The base station measures the phase delay of each tone and calculates the delay of the remote unit from the slope of the line of phase angle versus tone frequency. The base station transmits a signal to the remote unit that includes the magnitude and direction of the delay, which allows the remote unit to adapt the timing of its transmission to be synchronized with the other remote units.
