A method of communication between a user terminal powered by a battery and a base station allowing optimization of the management of the battery of the user terminal, includes a step of selecting from among terminals, termed surrounding terminals, powered by battery and situated in a zone within range of the base station, terminals whose distance with the user terminal is less than a predetermined distance and whose battery level is greater than a predetermined threshold, termed neighbour terminals, a step of configuring the neighbour terminals and the user terminal by way of a configuration setpoint, a step of transmitting data between the user terminal and the base station according to the configuration setpoint defining at least one neighbour terminal through which the data pass.

Method of communication between a battery powered terminal and a base station and associated communication network

A battery sharing method to increase the service life of the batteries of PMR terminals having important uses, such as the terminal of the head of a group such as the police, firefighters, or the like, is disclosed. The technique is based on the detection of neighboring networks and/or neighboring nodes. The detection is facilitated by reiterating a selection (or reselection) of cells and a handover (HO)/vertical handover (VHO) procedure, while relaying and coordinating transmission and reception. The aim of the techniques is to improve communications as well as the duration thereof, in order to enable improved management of the battery of each terminal and to broaden coverage in areas that are not served by a network.
