Properties of radio signals exchanged between the first unit and the second unit are measured ( ). A mode of informing the first unit of frame receipt status at the second unit during the message transfer transaction is selected ( ) based on the measured radio signal properties. The at least one frame is transferred ( ) from the first unit to the second unit while the first unit is informed of the frame receipt status at the second unit in accordance with the selected mode of informing.

Method and arrangement in a radio communication system

The present invention provides a method and system for quickly deallocating packet traffic channels. According to exemplary embodiments of the present invention, the capability of performing point-to-multipoint communications is provided on the PTCH by defining a multicast address that all mobiles read. Through the use of a multicast address, a plurality of mobile stations can simultaneously be notified of the termination of PTCH services. As a result, the network can reallocate PTCH resources in a minimum amount of time.
