| 摘要 |
The invention provides a data communication system including a communication network having a computer terminal for each subscriber to the network and adapted to communicate with other subscribers to said network, at least one communication unit adapted to communicate with each of the subscriber computer terminals, and synchronisation means for enabling a database associated with a subscriber's computer terminal to be synchronised with a database associated with said at least one communication unit. The communication network is preferably a cellular radio communication network, such as a GSM network, that is adapted to provide a short message service (SMS), the databases being synchronised using SMS messages. The synchronisation means enable identical information to be retrieved from each of the databases and respectively displayed on a display screen of the subscriber's computer terminal and on a display screen of the said at least one communication unit. The displayed information is preferably used to provide a response to a subscriber requiring expert advice. |
