Abstract: The mobile telephone system employs a fleet of satellites (214) and a set of gateway ground stations (210) arranged around the globe for handling communications to and from mobile communication units such as mobile telephones. Signals are transmitted between a subscriber (212) unit and the nearest gateway (210) via one or more of the satellites (214). The gateway is connected to a set of individuel service providers (216) such as local telephone systems. The individual service providers may be constrained for various reasons such as contractual or other legal constraints to handle communications only from subscriber units (212) located in certain geographical areas such as within only certain countries or portions of countries. For a mobile communication from a particular subscriber unit (212), the gateway selects (210) a service provider (216) capable of handling the communication. In one implementation, the selection is based upon the location of the subscriber unit and upon any references specified by the subscriber unit. In other implementations, the selection is based on other parameters such as the altitude, speed or velocity of the subscriber unit or the time of day or date upon which the communication is initiated.

Abstract: Disclosed herein is a system for rapidly resolving position with centimeter-level accuracy for a mobile or stationary receiver (4). This is achieved by estimating a set of parameters that are related to the integer cycle ambiguities which arise in tracking the carrier phase of satellite downlinks (5, 6). In the preferred embodiment, the technique involves a navigation receiver (4) simultaneously tracking transmissions (6) from Low Earth Orbit Satellites (LEOS) (2) together with transmissions (5) from GPS navigation satellites (1). The rapid change in the line-of-sight vectors from the receiver (4) to the LEO signal sources (2), due to the orbital motion of the LEOS, enables the resolution with integrity of the integer cycle ambiguities of the GPS signals (5) as well as parameters related to the integer cycle ambiguity on the LEOS signals (6). These parameters, once identified, enable real-time centimeter-level positioning of the receiver (4).

Abstract: Disclosed is a method for transmitting a signal from a base station transceiver system (BTS) to a base station controller (BSC) when there is no data transmitted from a mobile station while in discontinuous transmission (DTX) mode, in a mobile communication system. The mobile communication system includes a mobile station for transmitting and receiving data in a predetermined period, a base station transceiver system and a base station controller for controlling the base station transceiver system. Upon detection of the discontinuous transmission mode, it is determined what type of frame was last transmitted from the mobile station, and the present power control information is set according to the type of frame. If it is a null frame, the base station transceiver system sets previous power control information that the base station transceiver system has used for power control of the mobile station before detection of discontinuous transmission mode, to present power control information. Thereafter, the base station transceiver system transmits a reverse message including the present power control information to the base station controller over a dedicated control channel. If there is data being transmitted between the mobile station and the base station transceiver system at the time where the discontinuous transmission mode is detected, the previous power control information is set to the present power control information.

Abstract: There is disclosed a method for performing channel assignment in a base station for a mobile communication system. Upon receipt of a request for assigning a channel to a mobile station, a base station transceiver system (BTS) generates a connect message including channel information, which indicates a Walsh code, out of 256 Walsh codes, to be used for a channel to be assigned to the mobile station, and a quasi-orthogonal function (QOF) index. The BTS transmits the generated connect message to a base station controller (BSC). The BSC generates a connect ACK message for acknowledging the channel assignment-related information included in the connect message and transmits the generated connect ACK message to the BTS. Upon receipt of the connect ACK message, in the BTS assigns the channel that was acknowledged by the BSC to the mobile station.

Abstract: A method of establishing a supplemental channel (SCH) to provide burst timing for high-speed data transmission in a mobile communication system is disclosed. In the SCH establishing method, a source base station transceiver determines that a traffic burst exists and sends a target base station transceiver a burst request message. The burst request message includes forward and reverse burst timing information and channel use time information, which is determined in consideration of a discontinuous transmission (DTX) mode, in order to reserve necessary resources, when a large amount of high rate data is to be transmitted. Then, the target base station transceiver sends the source base station transceiver a burst response message including information about resources committed to the traffic burst.
