Abstract: The invention relates to a method for accomplishing a register recall from a subscriber unit of a radio system providing a wireless local loop, the radio system comprising a subscriber network element and base stations to transmit telecommunication signals between the subscriber units and a public switched telephone network. To obtain a register recall in a simple and fast manner, a register recall frame is transmitted from the subscriber unit in a conversion state of the unit to the subscriber network element, a message is awaited from the subscriber network element about receiving the frame, and diallings input from a user interface of the subscriber unit are transmitted on a speech path via the subscriber network unit to the public switched telephone network. The invention also relates to a subscriber unit and a subscriber network element.

Abstract: A method and a subscriber unit and a subscriber network element, in a radio system provided with a wireless local loop, for handling a collision of an outgoing call from the subscriber unit and a terminating call at the subscriber unit. When the collision is detected, the switching of the outgoing call is interrupted, a release frame is transmitted to the subscriber unit, a busy tone is transmitted from the subscriber unit to a subscriber in response to the release frame, a calling is transmitted to the subscriber unit, and the terminating call is switched to the subscriber unit after responding to the calling.

Abstract: The invention relates to a method for transmitting tariff data via radio-frequency signals to a chargeable subscriber unit (1) communicating with a telecommunication network (7). In order to charge the user of the subscriber unit as fairly as possible, a tariff frame corresponding to a lump sum is transmitted to the subscriber unit (1), charge-metering signals received from the telecommunication network (7) are counted, and when the monetary value corresponding to the number of the counted charge-metering signals exceeds a predetermined threshold value, a new tariff frame corresponding to a lump sum is transmitted to the subscriber unit (1). The invention also relates to a system where the method according to the invention can be applied.
