Abstract

A method and apparatus are provided for detecting an object to be detected. The object is associated with a profile, wherein the profile characterizes the reflection of a signal on the object. The method includes, for a device in a telecommunication network, the acts of selecting a first profile corresponding to a first object to be detected; requesting, based on the first profile, a resource allocation to the communication network; receiving the resource allocation from the communication network; transmitting a signal in the direction of a second object using the allocated resource; receiving a reflected signal, corresponding to the reflection of the transmitted signal on the second object; computing a second profile using the received reflected signal; and indicating the detection of the first object to be detected when the second profile matches the first profile.

Claims

1. A method of detecting an object to be detected, said object being associated with a profile, said profile characterizing reflection of a signal on the object, said method comprising, for a device in a telecommunication network, the acts of:

selecting a first profile corresponding to a first object to be detected,

requesting by the device, based on the first profile, a resource allocation to the communication network,

receiving the resource allocation by the device from the communication network,

transmitting a signal from the device in the direction of a second object using said allocated resource,

receiving a reflected signal, corresponding to the reflection of the transmitted signal on the second object,

computing a second profile using the received reflected signal, and

indicating detection of the first object to be detected when the second profile matches the first profile.

2. The method according to claim 1, wherein, in the act of requesting a resource allocation based on the first profile, the resource corresponds to a time slot at a defined time interval, said defined time interval being based on at least one attribute of the first profile.

3. The method according to claim 1, wherein the act of computing the second profile is computed based on the Doppler effect of the received reflected signal on the second object.

4. The method according to claim 1, wherein the first profile comprises attributes characterizing the first object and wherein the second profile comprises attributes characterizing the second object, said attributes comprising at least one attribute of the group consisting of range, azimuth, elevation and velocity.

5. The method according to claim 1, the act of indicating further comprising comparing attributes of the first and second profile in order to decide of a match between the first and the second profile.

6. The method according to any claim 1, said method further comprising an act of obtaining a request for triggering the selection of the first profile.

7. The method according to claim 1, wherein the act of selecting a first profile is performed automatically by the device.

8. The method according to claim 1, wherein the act of indicating further comprises comparing the computed second profile with at least one profile of a set of first profiles, said set of profiles being accessible to the device.

9. The method according to claim 1, wherein the resource allocated for detection is allocated with a high priority among the resources allocated in the communication network.

10. A device for detecting an object to be detected, said object being associated with a profile, said profile characterizing reflection of a signal on the object, said device, in a telecommunication network, comprising:

a selection unit configured to select a first profile corresponding to a first object to be detected,

a resource allocation request unit configured to request, based on the first profile, a resource allocation to the communication network,

a resource allocation reception unit configured to receive the resource allocation from the communication network,

a signal transmission unit configured to transmit a signal in the direction of a second object using said allocated resource,

a signal reception unit configured to receive a reflected signal, corresponding to the reflection of the transmitted signal on the second object,

a computing unit configured to compute a second profile using the received reflected signal, and

an indication unit configured to indicate detection of the first object to be detected when the second profile matches the first profile.

11. The device according to claim 10, wherein the computing unit is further configured to compute the second profile based on the Doppler effect of the received reflected signal on the second object.

12. The device according to claim 10, wherein the indicating unit is further configured to compare attributes of the first and second profile in order to decide of a match between the first and the second profile.

13. The device according to claim 10, said selection unit being further configured to obtain a request for triggering the selection of the first profile.

14. A system for detecting an object to be detected, said object being associated with a profile, said profile characterizing reflection of a signal on the object, said system comprising:

a telecommunication network,

an object to be detected, and

a device comprising;

a selection unit configured to select a first profile corresponding to a first object to be detected,

a resource allocation request unit configured to request, based on the first profile, a resource allocation to the communication network,

a resource allocation reception unit configured to receive the resource allocation from the communication network,

a signal transmission unit configured to transmit a signal in the direction of a second object using said allocated resource,

a signal reception unit configured to receive a reflected signal, corresponding to the reflection of the transmitted signal on the second object,

a computing unit configured to compute a second profile using the received reflected signal, and

an indication unit configured to indicate the detection of the first object to be detected when the second profile matches the first profile.

15. A non-transitory computer-readable medium having computer-executable instructions to configure a computer system to perform a method of detecting an object to be detected, said object being associated with a profile, said profile characterizing reflection of a signal on the object, said instructions comprising, for a device in a telecommunication network:

instructions that configure the computer system to select a first profile corresponding to a first object to be detected,

instructions that configure the computer system to request, based on the first profile, a resource allocation to the communication network,

instructions that configure the computer system to receive the resource allocation from the communication network,

instructions that configure the computer system to transmit a signal from the device in the direction of a second object using said allocated resource,

instructions that configure the computer system to receive a reflected signal, corresponding to the reflection of the transmitted signal on the second object,

instructions that configure the computer system to compute a second profile using the received reflected signal, and

instructions that configure the computer system to indicate detection of the first object to be detected when the second profile matches the first profile.
