摘要： In a time division duplex (TDD) system, compensation measurements are made for the transmission circuitry during the receive portion of the TDD cycle and compensation measurements are made for the receive circuitry during the transmit portion of the TDD cycle. A base station has multiple antennas for spatial, as well as spectral, spreading and despreading of discrete multitone spread spectrum (DMT-SS) communications. Each antenna has its own transmission path components and receive path components. The transmit amplifier, for example, in the transmit path and the receive amplifier, for example, in the receive path tend to drift in their characteristics over time. The invention manages the sequential testing of each respective transmission path and receive path for each antenna. The invention measures the drift of the transmit path components and the receive path components and prepares compensating weights to be applied to signals processed in each path.

摘要： A method for transmitting packetized data in a cellular communication system uses a dynamic channel assignment scheme. In this aspect of the invention a data control channel is used in addition to the data traffic channel. The mobile end system uses the data control channel to send a request for assignment of a channel for transmission of data--such as a particular frequency/time-slot in a TDMA system. The network responds with the identification of a particular channel that may be used for a particular time period to transmit data. In this aspect of the invention there is no dedicated channel that is used for data transmission. Rather, the network determines a channel that will be free for the specified time period and assigns it for data transmission.

摘要： A method and apparatus for determining the location of a mobile telephone within the serving area of a mobile telephone system. 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. In addition, the mobile telephone comprises a GPS receiver/processor for sending the most recent GPS coordinates of the mobile telephone which are within a predetermined confidence level to the mobile location module. These GPS coordinates are compared with the calculated location area to increase the accuracy of the location determination.

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.
