Abstract: A technique for transferring a data message between a first terminal device and a second terminal device via an intermediate terminal device includes: entering a data message into the first terminal device; transmitting the data message from the first terminal device to the intermediate terminal device; formatting the data message into at least one SMS (Short Message Service) message in the intermediate terminal device; and transmitting the at least one SMS message from the intermediate terminal device to the second terminal device. Formatting the data message may include formatting the data in a SyncML format. The intermediate terminal device may include a mobile terminal and the data message may be transferred from the first terminal device to the intermediate terminal device via a short range communication link which may include an IR or Bluetooth communication link.

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.
