Abstract (en)
[origin: WO2021048487A1] The invention relates to a method and a device for detecting the reachability of a terminal previously served by a first access device in a registration area of a communications network, the area comprising the first access device, which is incapable of managing resting and waking periods of the terminal, and a second access device, which is capable of managing said periods. A terminal, in particular in the passive state, is unable to update its location until it wishes to transmit data. However, if a network apparatus wishes to transmit data to said terminal, it must be able to contact the terminal. It therefore needs to communicate with the terminal during a period when the latter starts listening and waking up. If the network apparatus thinks that the terminal is served by an access station that does not manage the resting and waking phases of the terminal, it does not attempt to communicate with the terminal during these phases. The detection method enables this problem to be solved and enables improvement in the awareness of the network apparatus regarding the availability of the terminal.
