Abstract

A method of operating a server for remotely monitoring personal activity, the method comprising: generating and sending a message to at least one user equipment, UE, if one of the following conditions is met: the server receives a signal from an electrical plug device and the received signal is in accordance with an expected pattern of signals; or the server receives a signal from an electrical plug device and the received signal is not in accordance with an expected pattern of signals; or the server does not receive a signal from an electrical plug device when a signal is expected in accordance with an expected pattern of signals.

Claims

1. A method for remotely monitoring personal activity, the method comprising:

at an electrical plug device, sending a signal to a server each time an apparatus connected to the electrical plug device is switched on or switched off;

at the server, receiving the signal;

establishing whether the signal is in accordance with an expected pattern of signals of at least one of a plurality of signals wherein the expected pattern of signals is based on prior knowledge of personal activity;

generating a first message if the signal is in accordance with the expected pattern of signals or if the signal is not in accordance with the expected pattern of signals,

sending the first message to at least one of a plurality of user equipment, UEs; and

at the at least one of the plurality of UEs, receiving the message;

sending a second message from a first UE of the plurality of UEs to the server if the first message indicates that the signal is not in accordance with the expected pattern of signals, the second message indicating that a user of the first UE will take an action; and

sending a third message from the server to other UEs of the plurality of UEs to inform users of the other UEs that the user of the first UE will take an action.

2. The method of claim 1, wherein the at least one of the plurality of UEs is a mobile phone or a PC or a tablet computer.

3. The method of claim 1, wherein the expected pattern of signals is considered in a pre-set number of discrete time windows.

4. The method of claim 3, wherein the likelihood of receiving a signal in a time window depends on behavior in previous time windows and is calculated with a Markov model.

5. An assembly for remotely monitoring personal activity comprising a plug device and a server,

said plug device comprising:

means for plugging the plug device into a mains electrical socket;

means for receiving a plug from an electrical apparatus; and

means for communicating with a server;

the device being arranged to send a signal to the server if the state of the electrical apparatus changes;

said server comprising;

means arranged to generate and send a first message from the server to at least one of a plurality of user equipment, UEs, if one of the following conditions is met;

the server receives the signal from an electrical plug device and the received signal is in accordance with an expected pattern of signals;

or

the server receives the signal from an electrical plug device and the received signal is not in accordance with the expected pattern of signals;

or

the server does not receive the signal from an electrical plug device when a signal is expected in accordance with the expected pattern of signals,

wherein the expected patter of signals is based on prior knowledge of personal activity and is registered at the server by a user;

means arranged to generate and send a second message from a first UE of the plurality of UEs to the server if the first message indicates that the signal is not in accordance with the expected pattern of signals, the second message indicating that a user of the first UE will take an action; and

means arranged to generate and send a third message from the server to other UEs of the plurality of UEs to inform users of the other UEs that the user of the first UE will take an action.

6. The plug device of claim 5, wherein the server is a mobile network server.

7. The plug device of claim 5, wherein the server is an internet server and the plug device further comprises wireless communication means.

8. The plug device of claim 6, further comprising a subscriber identification module, SIM, card.

9. The plug device of claim 5, further comprising an electric current analyzer arranged to detect whether the electrical apparatus is switched on, switched off or on standby.
