Abstract

A method for retrieving a lost entity by means of a cell based wireless telecommunication network is disclosed, comprising

• • determining a presence probability distribution of the lost entity for a predetermined geographical area; and
  • transmitting information of the lost entity to at least one set of predetermined retrieving entities, as a function of the probability distribution, by means of the cell based wireless telecommunication network.
    Related systems, devices and wireless communication networks have also been provided.

Claims

1. A method for retrieving a lost entity by means of a cell based wireless telecommunication network comprising:

determining a presence probability distribution of said lost entity for a predetermined geographical area; and

transmitting information of the lost entity to at least one set of predetermined retrieving entities, as a function of said probability distribution, by means of said cell based wireless telecommunication network.

2. A method according to claim 1, further comprising mapping said presence probability distribution on a first set of geographically corresponding cells of said cell based wireless telecommunication network.

3. A method according claim 2, wherein said information is transmitted to retrieving entities which are present in a second set of cells.

4. A method according to claim 1, wherein said presence probability distribution is determined based partially or fully on environmental parameters and/or results of statistical analysis of historical data and/or models and/or facts and/or preferences of the lost entity.

5. A method according to claim 4, wherein said environmental parameters are provided by sensor devices positioned on said wireless network infrastructure.

6. A method according to claim 4, wherein said environmental parameters comprise wind direction.

7. A system for retrieving a lost entity, adapted for interacting with a cell-based wireless communication network comprising:

a means for determining a presence probability distribution of said lost entity for a predetermined geographical area;

a means for transmitting information of the lost entity to at least one set of predetermined retrieving entities by means of said cell-based wireless communication network, as a function of said probability distribution.

8. A system according to claim 7, further comprising a set of sensor devices adapted for measuring environmental parameters.

9. A system according to claim 7, further comprising a means for mapping said presence probability distribution on a first set of geographically corresponding cells of said cell based wireless telecommunication network.

10. A system according to claim 7, further comprising a means for transmitting information to retrieving entities which are present in a second set of cells.

11. A system according to claim 7, comprising a means for determining said presence probability distribution based on the location where said lost entity was seen for the last time and/or the time when said lost entity was seen for the last time and/or based on environmental parameters and/or results of statistical analysis of historical data and/or models and/or facts and/or preferences of the lost entity.

12. A cell-based wireless communication network comprising sensor nodes located at network infrastructure sites which are adapted for communicating environmental parameters to said cell-based wireless communication network.

13. A wireless communication network infrastructure element for use in a wireless communication network comprising at least one sensor adapted for measuring an environmental parameter, and a means for communicating the resulting measurement to said wireless communication network.

14. A device for use in retrieving an entity, wherein it is adapted for determining a presence probability distribution of said entity for a predetermined geographical area.

15. A module adapted for being comprised in a cell based wireless communication network, wherein it is adapted or arranged for mapping a presence probability distribution of an entity on a set of geographically corresponding cells of said cell based wireless telecommunication network.
