1. A method of detecting movement of a mobile transceiver in a radio system, which comprises at least one base station (1) and terminals (2-4), the method comprising the steps of:
- measuring the an acceleration of the mobile transceiver (2-4) by at least one acceleration sensor (114-116) and determining the a velocity of the mobile transceiver by integrating the acceleration, and determining the a frequency shift caused by the a Doppler phenomenon at the a frequency used for data transmission from the velocity of the mobile transceiver (2-4), in order to take the movement of the mobile transceiver into account in the at least one operation of the radio system.

Abstract
A mobile transceiver and a method of detecting movement of the mobile transceiver in a radio system. The radio system includes at least one base station and terminals. The movement of the mobile transceiver is measured by at least one acceleration sensor (114-116) to take the movement of the mobile transceiver onto account in the operation of the radio system.
