Understanding Telecommunications Technologies for Law Enforcement
Agents, Intelligence Analysts and Non-Telecom Engineers
Presented by:
Dr. Jerry Lucas,
President, TeleStrategies (PhD, Physics)
Dr. Matthew Lucas, VP,
TeleStrategies (PhD, Computer Science)
This one day, pre-conference training seminar provides a technology primer for Law Enforcement Agents, Intelligence Analysts, Vendors and Non-engineers, who need to understand the basics of today’s telecommunications networks and services provided in order to support lawful interception and counterterrorism programs.

Telecom Infrastructure and Lawful Interception
-
PSTN Basics:
What’s do LEAs need to know about the public switched
telecommunications network, circuit switching, digital transmission,
fiber transport , access ( analog, E-1, DSL, etc), signaling ( DTMF,
ISDN, SS7, ect), billing systems and call detail records.
-
Intercept LI
Architectures: ETSI standards overview for lawful intercept,
basic LI elements (access, delivery and collection function), call
information and call content data collection, SS7 probes and
relevant telecom network elements.
VoIP
Infrastructure and Lawful Interception
-
VoIP Basics: Circuit switching versus VoIP, softswitches,
gateways, VoIP over broadband and interconnection with the PSTN.
-
VoIP Intercept: Options for intercept, routers, session
borders controllers, CISCO IOS model, layer 2 intercept,
intelligent probes, LEA to telecom operator provisioning, mediation
setup/teardown, signaling and IP content collection.
P2P Infrastructure and Lawful
Interception/Blocking
-
P2P Basics: what’s peer to peer( P2P) networking, hybrid P2P
( e.g. Napster) vs. true P2P ( e.g. Gnutella), legitimate P2P
networks, what’s Skype and how it works.
-
Blocking: Skype and other P2P traffic detection, content
monitoring and filtering, other blocking approaches and
distinguishing legitimate from malicious traffic.
-
Deep Packet Inspection: what is it and why is it needed, how
does real time surveillance work, isolating traffic streams points
of DPI deployment and more.
Mobile Wireless Infrastructure and Interception
-
Overview: Infrastructure basics ( GSM, GPRS, EDGE, UMTS,
HSPDA and CDMA), smart terminals, HLR, VLR and IMS.
-
Wireless Intercept : intercept at the switch, cell site or
tactical monitoring, location based technologies to track targets,
what call usage data is available, call detail records, SIM vs.
phone memory, cell site analysis to established targets travel path
and more.
