Abstract
A remote machine (10) communicates with a server (24). A mobile telecommunications module (14) is used to send a unstructured supplementary services data (USSD) message from the remote machine, and the remote machine then switches off. By polling the server (24), using USSD, the mobile telecommunications module (14) can be kept normally off, saving power.
Claims15
A method of operating intermittently a remote apparatus (10) comprising a data system (12) for capturing data, displaying data and/or actuating based on data, a wireless modem (14) and a controller (16), the remote machine being able to communicate with a server (24) through a mobile telecommunications network, the method comprising:
- (a) leaving the wireless modem (14) switched off;
- and when data has been captured by the data system (12) and is ready to send to the server and/or at intervals carrying out steps (b) to (d):
- (b) automatically, in the controller (16), switching on the wireless modem (14);
- (c) sending a signal from the remote apparatus (10) to the server (24) using a signalling channel message, including the data that is ready to send if the amount of data that is ready to send is sufficiently small to include in the signalling channel message;
- and
- (d) automatically in the controller (16) switching off the wireless modem to release network resources and conserve power.
A remote apparatus (10), for intermittently communicating with a server, the remote apparatus comprising:
- a data system (10) for capturing data, displaying data and/or actuating based on data;
- a wireless modem (14) that can be independently switched on and off;
- and
- a controller (16), arranged to control the wireless modem (14);
- wherein the controller (16) is arranged to control the wireless modem (14) to be normally switched off, the controller being arranged, when data has been captured by the data capture system (12) and is ready to send to the server and/or at intervals:
- to control the remote apparatus (10) to automatically switch on the wireless modem (14);
- to send a signal from the remote apparatus (10) to the server (24) using a signalling channel message, including the data that is ready to send if the amount of data that is ready to send is sufficiently small to fit in the signalling channel message;
- and
- to automatically switch off the wireless modem (14) to release network resources and conserve power.
A network comprising a remote apparatus (10), for intermittently communicating with a server, the remote apparatus comprising:
- a data system (10) for capturing data, displaying data and/or actuating based on data;
- a wireless modem (14) that can be independently switched on and off;
- and
- a controller (16), arranged to control the wireless modem (14);
- wherein the controller (16) is arranged to control the wireless modem (14) to be normally switched off, the controller being arranged, when data has been captured by the data capture system (12) and is ready to send to the server and/or at intervals;
- to control the remote apparatus (10) to automatically switch on the wireless modem (14);
- to send a signal from the remote apparatus (10) to the server (24) using a signalling channel message, including the data that is ready to send if the amount of data that is ready to send is sufficiently small to fit in the signalling channel message;
- and
- to automatically switch off the wireless modem (14) to release network resources and conserve power;
- and a server (24), wherein
- the server (24) is arranged to store data for the remote apparatus (14);
- and
- on receipt of a signal from the remote apparatus (10) through the USSD channel, the server (24) is arranged to send a message back to the remote apparatus (10) indicating whether the server (24) has data to send to the remote apparatus (10), and
- if the message indicates that the server (24) has data to send to the remote apparatus (10), to send the data to the remote apparatus (10).
