INTERCEPTION METHOD INTERWORKING WITH COMMUNICATION NETWORK AND INTERNET NETWORK

摘要

Disclosed is an interception method that interworks with a communication network and an Internet network. A law enforcement agency system verifies whether an interception target presently uses an Internet service by using a terminal other than a terminal registered as the interception target on the basis of Internet service access information of the interception target. When the interception target uses the Internet service by using the other terminal, the law enforcement agency system updates interception target information on the basis of IP address information of the corresponding terminal, which is included in the Internet service access information and transmits the updated interception target information to a communication service provider.
