Abstract:
A method for transmitting short messages between a portable part (PP), a fixed part (FP), and a short message service center (SC) so that the information is transferred between the portable part (PP) and the fixed part (FP) through a radio interface, comprising the steps of:a first data transfer protocol corresponding with the DECT system is used in the data transfer between the portable part (PP) and the fixed part (FP), anda second data transfer protocol is used in the data transfer between the fixed part (FP) and the short message service center (SC), andwherein the first data transfer protocol and the second data transfer protocol both comprise different protocol layers, and a determined protocol level is used as an interworking level between the first data transfer protocol and the second data transfer protocol so that the interworking level of the second data transfer protocol interworks with the respective level of the first data transfer protocol; andwherein there are protocols on at least two layers comprising a higher protocol layer and a lower protocol layer. the higher protocol layer comprising a short message transfer protocol (SM- TP), and said interworking level comprises a protocol under the short message transfer protocol (SM-TP) and the protocol under the transfer protocol interworks with the respective DECT protocol, whereas the transfer protocol (SM-TP) is transmitted between the portable part and the short message service center substantially intact.
