Lawful Interception

PertSol iNterceptor is a Lawful Interception system unified for network operators and telecom service providers which is fully compliant with international standards and has a proven track record. It is a complete solution that is capable of handling both circuit switch and packet switch traffic from both legacies as well as the latest telecom technologies including 2G, VoIP, 3G, 4G, 5G, IMS,5G Interception, NGN, PSTN, IPLC, OTT, IFMS, PS Interception, etc.

The core purpose of iNterceptor is to intercept the traffic and convert intercepted traffic into a format suitable for delivery to National Authorities or Law Enforcement agencies, over a secure network. It can also retain the intercepted traffic for future use by the LEAs compliant with international standards and has a proven track record. 

iNterceptor along with PertSol iNteliProbe forms one of the most comprehensive interception solutions available in the market. PertSol iNteliProbe supports capturing 100% of traffic, decoding the traffic from layer 2 to layer 7, and then either transmittal of interception of data and decoded data to the LEAs or its storage for future use. The probes actively support the capture and reconstruction of all non-encrypted IP, and voice traffic this includes reconstruction and capture of VoIP calls, TDM calls, and IP traffic reconstruction.

iNterceptor Lawful Interception system is designed to change and adapts as per the latest network upgradation and technologies. It protects investments through its modular setup, accommodating network expansion as well as network changes. It can also integrate with existing Lawful Interception vendors incorporating it into a centrally managed unified solution.

5G Ready Solutions

PertSol works closely with the leading telecom company, MNOs, network equipment providers, and regulators to evolve its products as per the technology and market trends. In its bid to keep track of the market and latest technology, PertSol has upgraded its product as per the 5G standards released by 3GPP in its Release 15. PertSol iNterceptor has also been upgraded to fulfill lawful interception system requirements for both standalone and non-standalone 5G networks.

iNterceptor: Benefits

High
Performance
Mediation

iNterceptor is capable of handling networks with very high throughput requirements. It can handle multiple 100 Gbps links and is capable of selecting required traffic from these links. PertSol iNteliProbe has been tested and implemented for traffic up to 40 Gbps per probe. The integrity check mechanism periodically checks the network elements and if required corrects the erroneous states. It will query the network element for the placed intercepts and add missing intercepts, remove invalid intercepts, etc. This mechanism is used to detect and correct both network flaws as well as tampering with the interception solution. In case of correction of an erroneous state, this will be notified to the operator.

Adapters

iNterceptor has a vast range of Input/Output adapters which makes it compatible with all the available access technologies and network equipment of all the major equipment providers. If required, customer-specific Input or Output adapters can be developed.
iNterceptor allows configuration of multiple Input and Output Adapters to be combined in one system and support any situation like inter-working between different technologies or scaling up to include latest technology. Due to iNterceptor’s modularity, telecom operators can leverage their investment for a longer duration and scale up their network with more flexibility.

Network

Due to its design philosophy, iNterceptor can support hybrid networks with equipment from different vendors on same server. When networks grow or change, iNterceptor can easily be extended to cater for the growth in traffic volumes or new types of network elements. Unified solution for all interception requirements of a service provider which is compliant to international standards like 3GPP, ETSI, ATSI, ANSI, CALEA and others. It also complies with local LI regulations of many countries across the world.
