MESSAGE TRANSMISSION SYSTEM AND METHOD FOR USING SIM CARDS VIA REMOTE ACCESS FOR ECONOMICAL CONNECTIONS BETWEEN FIXED AND MOBILE RADIO TELEPHONE NETWORKS

摘要

Methods using a central SIM server and simulated SIM cards for measuring network quality at regular intervals are already known. However, too little attention is given to the fact that the control of the information to be transmitted via a central SIM server with a simulated SIM card is as a rule locally time-critical. In order to configure a message transmission system using SIM cards via remote access in such a way as to enable the utilization of transmission paths with a network-internal delay time in the range of seconds, the SIM server comprises a SIM card array having SIM cards arranged at least in lines and a SIM management device having a SIM multiplexer connected downstream of the SIM card array. The SIM server is connected to a standalone device via a transmission network, said standalone device having a SIM card emulator and a SIM card interface. A profile data record for SIM card emulation is stored in the memory of the SIM card emulator in order to remotely access the standalone device and only the authentication is transmitted via the transmission network. The invention relates to the field of message transmission systems.
