摘要
A cellular radio communication system including a cellular radio communication network, such as GSM, adapted to provide a short message service (SMS) and including a plurality of mobile telephone stations and a number of base stations, each one of which is connected to a public switched telephone network and adapted to communicate with a number of said mobile stations. The system includes at least one portable graphic display unit, for example, a portable personal computer (PPC), such as a laptop computer, adapted to communicate with the network, via a mobile station, using SMS and, in response to receipt of SMS messages, to selectively display stored graphic images and to selectively superpose stored geographically related information symbols on a displayed image. The information symbols, superposed on a displayed map image, are continually updated with current information by the SMS messages. The graphic images and symbols are preferably stored by the PPC, for example, on a CD-ROM and/or hard disc.
