LIMS Access Points
LIMS Access Points can be used for targeted interception as well as for the generation of IPDRs (IP
data records) for a large range of communications services. For this purpose, the LI probes leverage
state-of-the-art deep packet inspection technologies.
The LI probes are fully integrated with Utimaco LIMS
and the Utimaco DRS management system, serving
both the telephone monitoring as well as the deep packet inspection markets.
Real-time
Monitoring
with LIMS Access Points
Telecom operators have been performing real-time monitoring of network connections for years to
achieve various aims, for example to monitor service quality, to perform analyses, for fraud
detection, E911 location and billing.
Specialized network probes are typically connected to the network by non-intrusive taps, thus
receiving a copy of the communications traffic.
Utimaco offers a range of network probes, Utimaco LIMS Access Points, that analyze all network
data based on defined filter rules and which can extract data of specific interest.
Law enforcement and intelligence agencies make use of such probes for non-intrusive surveillance
of communication links.
Network Access and IP Monitoring
LIMS Access Point AAA detect user logins and device registrations by monitoring RADIUS and DHCP data in the core network. When a target is identified, LIMS automatically triggers the interception of the correlated IP data, either on IP routers with internal interception function or on one or more LIMS Access Point IP.
LIMS Access Point E-Mail are deployed in the core network of service providers to monitor and intercept targeted e-mails. As with all Utimaco LI probes they operate fully transparently, without any impact on the service.
VoIP / VoLTE / VoWIFI
Voice-over-IP monitoring requires deep analysis of the SIP signaling in the VoIP/VoLTE core network. LIMS Access Point VoIP can detect and intercept targeted SIP calls even with call forwarding and in call conferences.
Web Services
Lawful interception of web services requires deep packet inspection of http-based application protocols. The LIMS Access Point DPI can be tailored to intercept specific application data in the service provider’s core network.
Mobile Data
LIMS Access Point GTP enables passive interception of targeted data at various points in the network of a mobile operator. The traffic can be selectively extracted from 1G, 10G and 100G links in the radio access links, core networks and at roaming exchanges.
IP-Loggging
Tracing back source IP addresses in a carrier network requires high-speed logging of all IP
flows through Network Address Translation (NAT/NAPT).
This compute and data intensive task is a big burden on carrier routers and can be
accomplished by hardware accelerated LIMS Access Points in a much more efficient and
transparent way.
Our probes aggregate and correlate all IP logs with AAA data and forward the records to
Utimaco DRS in near real-time.
Mobile Voice, Fixed Voice
In cases where access to the call switching centers is not available, phone calls may be intercepted passively in the radio access network, respectively from the transmission line. Utimaco provides custom LI probes for IP-based and TDM-based links, such as A- and IuCS- interfaces.
Benefits
Transparent - Independent of the serving network, no negative impact on performance or
availability of the service, invisible for subscribers
High capacity – LI probes can be designed to capture large amounts of traffic and monitor
thousands of identities at the same time
Secure - probes are segregated from the serving network and protected from unauthorized access
Standards-compliant ETSI/3GPP compliant hand-over of intercepted calls and data via ISDN or IP
