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, said the plurality of access points being configured to:
- communicate by radio link with the plurality of remote-reading terminals to be updated, andcommunicate with a management server of the remote-reading installation by an intermediary of a telecommunication network;
each remote reading terminal of the plurality of emote-reading terminals to be updated being associated with an access point of the plurality of access points in order to transmit 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 the 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, whilst allowing the reception of the update data by the plurality of remote-reading terminals to be updated; and
