Abstract
The invention relates to wireless telecommunication systems employing ATM technique (Asynchronous Transfer Mode) in transmission systems. A signalling arrangement between network elements comprises a protocol stack comprising on top a layer 3 user function for signalling between a wireless mobile station and a network, an ATM adaptation layer, an ATM layer and a physical later. In accordance with the invention the ATM adaptation later comprises on top a service-specific coordination function immediately between said higher user function and a service-specific connection-oriented protocol. Said service-specific coordination function comprises as functions the adaptation of the user function to the service-specific connection-oriented protocol and the establishment, discrimination and release of the signalling connections of the ATM adaptation later needed for conveying signalling messages of the layer user function. The invention provides a simple protocol stack that is easy to implement. The efficiency of the protocol stack also increases as the number of layers decreases.
