Remote distribution of a software update to remote-reading terminals
First Claim
1. A method of managing a software update of a plurality of remote reading terminals to be updated in a remote-reading installation, the remote-reading installation comprising a plurality of access points, the plurality of access points being configured to:
- (1) communicate by radio link with the plurality of remote-reading terminals to be updated, and (2) communicate with a management server of the remote-reading installation by an intermediary of a telecommunication network, where each remote reading terminal of the plurality of remote-reading terminals to be updated is associated with an access point of the plurality of access points in order to transmit of remote-reading data to the management server, the method comprising the steps of;
(a) transmitting a message for planning reception of update data to the plurality of remote-reading terminals to be updated by the intermediary of their associated access points, the planning message comprising a start time for distribution of the update data;
(b) selecting a set of access points among the plurality of access points to limit the number of access points used for distributing the update data, while allowing the reception of the update data by the plurality of remote-reading terminals to be updated; and
(c) transmitting the update data by the selected set of access points, at the distribution start time,wherein step (b) comprises selecting a minimum number of access points for transmitting the updates to all of the remote-reading terminals to be updated simultaneously, the selection of the minimum number of access points being based on transmission range areas of the access points and locations of the remote-reading terminals relative to the transmission range areas, such that the transmission range areas of the minimum number of access points cover the remote-reading terminals.
