Abstract

Provided are an electronic surveillance system and a method thereof. In the electronic surveillance system that performs electronic surveillance on a subscriber in a communication network, the electronic surveillance system includes: one or more communication service providers that provide retained data, which is information generated while the subscriber uses a communication service; a dedicated storage that stores and manages the retained data provided by the communication service providers; and a law enforcement agency that requests the dedicated storage to send electronic surveillance information on a specific subscriber so as to be provided with the surveillance information when the electronic surveillance information on the specific subscriber is required. Accordingly, retained data, which is subscriber electronic surveillance information is integrally managed and stored in a dedicated storage. Thus, a communication service provider can reduce costs when a law enforcement agency requests subscriber electronic surveillance information. Furthermore, the subscriber electronic surveillance information can be efficiently managed.

Claims

1. A method for an electronic surveillance system to perform electronic surveillance on a subscriber in a communication network, the method comprising:

receiving, from at least one communication service provider, retained data including subscriber information, the retained data being information generated while subscribers use communication services of the communication service provider;

classifying and storing the retained data provided by the communication service provider; and

searching the retained data for retained data on a specific subscriber when a request for the retained data on the specific subscriber is received from an electronic surveillance requestor that includes a law enforcement agency, and providing the results of the searching the retained data to the electronic surveillance requestor.

2. The method of claim 1, wherein the providing the results of the searching the retained data comprises receiving a message related to the request for the retained data on the specific subscriber from the electronic surveillance requestor through an interface that supports a handover interface A (HI-A).

3. The method of claim 1, wherein the results of the searching the retained data is provided to the electronic surveillance requestor through an interface that supports a handover interface B (HI-B).

4. A method for an electronic surveillance system to perform electronic surveillance on a subscriber in a communication network, the method comprising:

receiving, from an electronic surveillance requestor including a law enforcement agency, retained data including subscriber information provided by at least one communication service provider, the retained data being information generated while subscribers use communication services of the communication service provider;

classifying and storing the retained data; and

searching the retained data for retained data on a specific subscriber when a request for the retained data on the specific subscriber is received from the electronic surveillance requestor, and providing the results of searching the retained data to the electronic surveillance requestor.

5. The method of claim 4, further comprising:

receiving, by the electronic surveillance requestor, from at least one communication service provider, the retained data including subscriber information; and

analyzing the retained data, and providing the retained data to the electronic surveillance system based on a result of the analyzing.

6. The method of claim 4, wherein the providing the results of searching the retained data comprises receiving a message related to the request for the retained data on the specific subscriber from the electronic surveillance requestor through an interface that supports a handover interface A (HI-A).

7. The method of claim 4, wherein the results of searching the retained data is provided to the electronic surveillance requestor through an interface that supports a handover interface B (HI-B).

8. An electronic surveillance system for performing electronic surveillance on a subscriber that uses a communication service, the system comprising:

a law enforcement agency configured to receive, from at least one communication service provider, retained data including subscriber information, analyze, and classify the retained data, the retained data being information generated while subscribers use communication services of the communication service provider; and

a dedicated storage unit configured to receive the retained data from the law enforcement agency, store the received retained data, search the retained data for retained data on a specific subscriber when the law enforcement agency requests the retained data on the specific subscriber, and provide the results of searching the retained data to the law enforcement agency.

9. The electronic surveillance system of claim 8, wherein the law enforcement agency transmits a message related to a request for the retained data on the specific subscriber to the dedicated storage unit through an interface that supports a handover interface A (HI-A).

10. The electronic surveillance system of claim 8, wherein the dedicated storage unit transmits the results of searching the retained data to the law enforcement agency through an interface that supports a handover interface B (HI-B).
