Checks, balances, and measurements for your Lawful Interception IT Architecture

Lawful Interception (LI) architectures deployed in telecommunication networks consist of many complex building blocks which are connected and integrated together. If one of these building blocks fails for whatever reason, potential important and often crucial intercepted data can be lost. The result: insufficient proof in court and more important non-compliance with local regulation.

Both telecommunication operators and LEA’s have an increased demand to determine if the end-to-end communication and IT technology chain is acting according to requirements and standards. Hence the need for a comprehensive but cost-efficient monitoring and measurement solution was born. A solution reducing the complexity for all stakeholders in the domain whilst creating the unfailingly and consistently data you need for compliance (Network Operators) and guarantee to receive the right data (LEA’s).

Group 2000 has a long history regarding providing innovative and sustainable compliance solutions like LIMA Élite.

LIMA Élite was built around an existing monitoring and measurement platform used to simulate targets as the modems act as normal phones. Various actions are supported by the platform, like connecting to the right network and technology. Support for dialing, sending SMS and retrieving websites via the mobile connection was added to  complete the functionality of the existing platform. A new backend system orchestrates all tests and also acts as a law enforcement monitoring facility (LEMF) to validate the output of the LI environment.

Furthermore, we correlate the intercepted data with the right action taken and to verify that the interception is working. All relevant ID’s are embedded in the technology and functionality in order to ensure that correlation is done in a perfect way independently of the execution of the actions to support long delays in delivery of the intercepted data.

The LIMA Élite backend supports many input formats, like ETSI-232, LEMF specific export formats, ETSI-671, and many others. To support the flexibility in configurations of the backend, the software makes use of flexible and easy to configure open source technology like Docker.

The modularity of LIMA Élite solution also opens chances for other derived, however, useful solutions, which might be topic for a follow-up blog.
