Abstract: The invention relates to a locating method and an arrangement for determining the location of a terminal in a radio system comprising a plurality of base stations and terminals. At least two base stations with known locations transmit a signal used in locating the terminal, and the signals are transmitted in beams with directional antenna patterns and the direction of the beams is changed as a function of time. The terminal determines the location of the base station and the transmission direction of the signal used in location determination by means of the beam transmitted by said at least two base stations. Since the terminal is located at the intersection of the beams of the base stations transmitting from known locations, the location of the terminal can easily be determined. The solution takes multipath propagation into account.

Abstract: A superregenerative circuit which is operable in a transmit mode and a receive mode of operation. A superregenerative oscillator and a single antenna are functional in both modes. To minimize any undesired RF energy which may be radiated during the receive mode of operation, the circuitry includes decoupling means connected between the antenna and the oscillator. During reception, the oscillator is periodically quenched, and received signals are recovered by circuitry which obtains, during unquenched periods, time samples indicative of the time required for the RF energy to build up to a predetermined level in the oscillator circuit.

Abstract: Landline facilities are linked to a wireless mobile network for calling party pays calls between wireless subscriber units. The wireless mobile network is provided with the ability to recognize that a called wireless station is a calling party pays subscriber. The wireless mobile network routes the call to a landline facility to undertake interactive communication with the calling station to determine whether the caller will agree to pay for both the called party's air-time charges and the calling party's air-time charges for the call. The landline facility can then access a database to determine if the carrier with which it is associated can provide billing functions with respect to the calling subscriber and, if so, activate such functions for a carrier entity so identified.
