摘要： Various arrangements for managing wireless network communication are described. Two cells using different radio access technologies (RATs), such as a 3G cell and a 4G cell, may provide overlapping coverage. A first cell using a first RAT, under certain circumstances, may be permitted to enter a powered down state such that less power is consumed. User equipment may communicate with the cell using the second RAT as the preferred network and only communicate with the cell using the first RAT when a service available through the first RAT but not the second RAT has been requested. Upon a request from the second cell, the first cell may enter a powered up state.

摘要： A novel power conservation scheme is provided for conserving power in client terminals by using a proxy server. The client terminal, having a low-power communication interface and a high-power communication interface, may power down its high-power communication interface, to conserve power. Prior to shutting off its high-power communication interface, the client terminal may assign a host terminal to act as a proxy for the client terminal. The host terminal monitors the paging channels for the client terminal via a high-power communication interface. If the host terminal detects a paging message for the client terminal, it forwards at least a portion of the paging message to the client terminal via a low-power communication interface. Upon receipt of the paging message from the host terminal via its low-power communication interface, the client terminal may power up its high-power communication interface and directly respond to an access terminal that initiated the paging message.

摘要： Techniques for extending coverage of a wireless communication network (e.g., a cellular network) to indoor and other locations are described. A wireless device may communicate with a base station in a wireless network via downlink and uplink frequency channels in a licensed frequency band using frequency division duplexing (FDD). The wireless device may communicate with a piconet base station (PBS) in a pico network (piconet) via the uplink frequency channel using time division duplexing (TDD). The PBS may communicate with the wireless device on the uplink frequency channel and may exchange data with the wireless network via a wireline communication link. The PBS may forward data received from the wireless device to the wireless network and may also forward data received from the wireless network for the wireless device to the wireless device. The PBS may receive paging messages from the wireless network for the wireless device and may forward the paging messages to the wireless device.

摘要： A system for facilitating handoff adapted for use with a telecommunications network. The system includes position equipment for determining the location of a mobile transceiver within a region containing a first cell and a second cell. A comparison circuit compares the location with a predetermined handoff area within the region and provides a control signal in response thereto. A handoff initiation circuit initiates handoff of the mobile transceiver between the first cell and the second cell in response to the control signal. In a specific embodiment, the handoff is a hard handoff. The position equipment includes Global Positioning System (GPS) equipment including a mobile unit GPS receiver and signal interface. The comparison circuit includes a positional database that stores latitudinal and longitudinal information corresponding to the predetermined handoff area. The comparison circuit also includes a Code Division Multiple Access selector. The selector begins tracking the position of the mobile transceiver when it is within a predetermined range of the predetermined handoff area. In a specific embodiment, the handoff initiation circuit includes a base station controller. The position equipment includes a base station positional detection system and a mobile unit positional detection system for determining the location of the mobile transceiver. The position database has map information depicting the coverage area of the first and second cells and the predetermined handoff area. The selector runs software for comparing the location to the map information and providing the control signal when the location is within the predetermined handoff area. The base station includes and implements instructions for completing hard handoff in response to the control signal.
