LAWFUL INTERCEPTION OF PSTN /GSM /UMTS ETC. NETWORKS AND MONITORING CENTER
Lawful Interception (LI) is the legally approved interception of telecommunications networks and has become an important tool for Law Enforcement Agencies (LEA s) around the world. Lawful Interception provides access to calls and call-related information (telephone numbers, date, time, etc.) within telecommunication networks, and delivers this data to a strategic Monitoring Center (MC). The MC can decode, store and playback/ view the data (call, data, fax). The interface between the MC and the telecommunication network varies depending on the networks (PSTN, GSM, GPRS, UMTS, CDMA, IP, etc.) and the switches used (Nokia-Siemens, Ericsson, Huawei, Alcatel-Lucent, Cisco, Juniper, etc.). Such an MC gives access to an entire country's telecommunication network from one central place, but it needs the support of operators and the relevant interception capabilities of the network elements (Hardware and Software).
