Abstract

An electronic monitoring system located in a second service area when an electronic monitoring target has moved from a first service area having a first authority to the second service area having a second authority starts electronic monitoring for the electronic monitoring target that has moved into the second service area, configures a temporary electronic monitoring authority based on the first authority and the second authority, and executes the electronic monitoring on the electronic monitoring target in the second service area according to the configured temporary electronic monitoring authority.

Claims

1. A method for performing electronic monitoring on an electronic monitoring target when the electronic monitoring target has moved from a first service area having a first authority to a second service area having a second authority by an electronic monitoring system located in the second service area, the method comprising:

receiving an electronic monitoring request on the electronic monitoring target; and

executing the electronic monitoring on the electronic monitoring target in the second service area based on the first authority and the second authority responding to the electronic monitoring request.

2. The method of claim 1, wherein

each of the first authority and the second authority includes at least one of electronic monitoring target information, electronic monitoring related information, electronic monitoring information, a service range of an electronic monitoring target, and a period of electronic monitoring,

the electronic monitoring target information includes at least one of the name, ID, registration number, telephone number, and address of the electronic monitoring target,

the electronic monitoring related information is information that is generated when the electronic monitoring target performs communication, and

the electronic monitoring information includes communication contents between the electronic monitoring target and other targets.

3. The method of claim 2, further comprising configuring a temporal electronic monitoring authority including both of the first authority and the second authority,

wherein the executing the electronic monitoring executes the electronic monitoring on an electronic monitoring target in the second service area based on the temporal electronic monitoring authority.

4. The method of claim 1, wherein

the executing the electronic monitoring includes

transferring electronic monitoring results acquired by executing the electronic monitoring to an external law enforcement agency system.

5. The method of claim 4, wherein

the transferring the electronic monitoring results includes

transferring all or a portion of the electronic monitoring results to the law enforcement agency system according to a concordance degree of the first authority and the second authority.

6. The method of claim 5, wherein

the transferring the electronic monitoring results further comprises

temporally storing an electronic monitoring result corresponding to a portion that the first authority and the second authority discord from each other among the results of the electronic monitoring for the electronic monitoring target.

7. The method of claim 6, wherein

the transferring the electronic monitoring results includes

when authority on the electronic monitoring target is approved, transmitting the temporally stored electronic monitoring result, and

when authority on the electronic monitoring target is not approved, deleting the temporally stored electronic monitoring results.

8. The method of claim 4, wherein

the executing the electronic monitoring includes

confirming whether the electronic monitoring system located in the second service area can execute the direct electronic monitoring,

when it is confirmed that the electronic monitoring system cannot execute the direct electronic monitoring, transmitting contents of the communication on the electronic monitoring target to another electronic monitoring system that is located in a different service area from the second service area to transmit the electronic monitoring results to the law enforcement agency system through the another electronic monitoring system, and

directly executing the electronic monitoring for the electronic monitoring target when it is confirmed the electronic monitoring system can execute the direct electronic monitoring.

9. A method for allowing a first electronic monitoring system to execute electronic monitoring on an electronic monitoring target that exists in a first service area to which the first electronic monitoring system belongs, the method comprising:

executing the electronic monitoring on an electronic monitoring target that exist in the first service area according to the corresponding electronic monitoring authority;

confirming whether the direct electronic monitoring is executed according to the electronic monitoring authority; and

when the direct electronic monitoring is impossible, transmitting contents of communication of the electronic monitoring target to a second electronic monitoring systems that are located in second service areas that are different from the first service area to transmit the electronic monitoring results to a external law enforcement agency system through the second electronic monitoring systems.

10. The method of claim 9, further comprising:

directly executing the electronic monitoring for the electronic monitoring target when the electronic monitoring is to be directly executed; and

directly transmitting a result of the execution of the electronic monitoring to the external law enforcement agency system.

11. An electronic monitoring method of an electronic monitoring system, comprising;

executing electronic monitoring on an electronic monitoring target in a second service area of the electronic monitoring system when the electronic monitoring target moves from a first service are to the second service area;

temporally storing a result of the electronic monitoring execution; and

waiting for an authentication message for the execution of the electronic monitoring on the electronic monitoring target in the second service area.

12. The method of claim 11, further comprising:

transmitting the temporally stored result of the electronic monitoring execution when receiving a positive authentication message for the electronic monitoring execution.

13. The method of claim 11, further comprising:

discarding the temporally stored result of the electronic monitoring execution when receiving a negative authentication message for the electronic monitoring execution.

14. The method of claim 11, further comprising:

discarding the temporally stored result of the electronic monitoring execution when the authentication message is not received with a maximum delay period.
