摘要： In a discrete multitone spread spectrum 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.

摘要： An arbitration controller provides arbitration on a multipoint, high speed serial bus with a plurality of drivers. Each driver includes a data input pin, an output enable pin, and an output pin. The bus defaults to a first state when the output of the plurality of drivers are set to high impedance. The arbitration controller eliminates any unstable output states on the drivers by controlling the input signals on the drivers. The arbitration controller detects when the bus is in an arbitration mode. When this is detected, the arbitration controller inputs data to the output enable pin and inputs an opposite state of the first state to the data input pin. Further, the arbitration controller detects when the bus is in a data mode. When this is detected, the arbitration controller inputs data to the data input pin and inputs a driver control signal to the output enable pin.

摘要： A method and apparatus for determining the location of a mobile telephone within the serving area of a mobile telephone system are disclosed. A mobile switching center analyzes the calling mobile telephone number and called telephone number to determine if a location function is required. Upon initiation of the location function by the mobile switching center, a mobile location module calculates a location estimate of the mobile telephone. The mobile location module receives a list of signal strengths received by the mobile telephone from cell site antennas within the serving area. The distance between the mobile telephone and a plurality of cell site antennas is calculated using a technique which reduces the error component of the calculated distances. These reduced error distances are used to geometrically determine an estimate of the location area within the sewing area of a mobile telephone system.

摘要： A device and method wherein, using a keypad such as a standard alphanumeric telephone-style keypad, text entry is improved by employing a key-press combination which indicates which of the multiple characters associated with a key is chosen. The user will push-and-hold a first key, then press a second key; the position within the keypad, such the row number, of the first key indicates which of the characters represented by the second key are chosen. In this way, any standard character can be selected with a two-key combination.

摘要： A system is provided for receiving prepayment of telecommunication services is provided. The system comprises a wireless communication network, a wireline communication network, and a pre-payment server communicating with both the wireless communication network and the wireless communication network. The prepayment server stores a monetary amount associated with the telecommunication time paid for by a subscriber. A measuring module operating on the prepayment server monitors the amount of time the subscriber uses both the wireless communication network and the wireless communication network and decreasing the monetary amount accordingly. The system enables a subscriber to make a single prepayment for telecommunication services, and the amount applies to both the subscriber's wireline or wireless telecommunications devices.
