LIMA Lawful Intercept

 The LIMA Management console is designed to fulfill a central role in our platform. Its scalable design allows it to be deployed in solutions ranging from a self-contained lawful interception solution in a single unit to a distributed system spanning multiple countries and operators.
As a user-friendly and field-proven solution, our LIMA Management console supports operators to manage and oversee their active warrants from a central location, regardless of the type and number of networks in which the interception measures are deployed. It protects investments through its modular setup, accommodating network expansion as well as network changes. The LIMA Management system also integrates with existing legacy Lawful Interception solutions and manages these solutions where the LIMA umbrella functions as a centrally managed solution. 

 Our LIMA Mediator can be integrated with a wide variety of network elements. To accommodate this variety of situations, our LIMA Mediator is designed around the concept of using input adapters that handle intercepted X2 (IRI or CDC) and X3 (CC or CCC) traffic. Input adapters are available for most network equipment commonly found in telecom and ISP networks. This includes adapters for PSTN/ISDN, VoIP/IMS/LTE, E-Mail, fixed IP, mobile IP, including support for the latest generation of 5G X-interfaces. Many adapters have been factory-tested with the network equipment vendors. On the output side, the LIMA Mediator supports all commonly used handover standards, implemented by output adapters. Supported protocols include ETSI TS 102 232, ETSI TS 103 120, ETSI ES 201 671, 3GPP TS 33.108, J-STD-025-B, ATIS T1.678 DSR, ATIS LEAS, Packetcable CBIS. Country specific requirements can be supported also.  To control the outbound bandwidth needs in a 5G environment, the LIMA Mediator provides the capability for layer-3 and layer-4 black/white list filtering. 

  The LIMA IP monitor is a robust, powerful and integrated IP probe which combines multiple IP interception functions in one physical system. The probe is able to intercept and capture all common IP, Email and VoIP traffic. The LIMA IP monitor is truly flexible, powerful and multi-functional whilst combining traffic analysis, interception and mediation in a single box when combined with the LIMA Mediator.

The LIMA IP monitor is a passive probe, which can be easily installed in a network. Implementation of the interception solution requires minimal impact and visibility by avoiding integration with existing network elements.

CC-PAG or CC PoI Aggregation is an optional component in the 3GPP 5G LI Architecture, but would be beneficial for any carrier requiring a high speed 5G LI architecture. When deploying the LIMA CC-PAG function as a component in high speed 5G LI architecture, carriers will benefit from optimized network connectivity and improved UPF efficiency. Increased UPF efficiency is achieved by offloading specific UPF function to our LIMA CC-PAG, which will reduce the number of required UPF components. Main functions provided by the LIMA CC-PAG function are the aggregation of CC from different CC-POIs towards the MDF3 function of the LIMA Mediator, support for a more efficient X3 transport protocol from CC-POI towards the MDF3 function of the LIMA Mediator, offload encryption from UPF to CC-PAG for X3 traffic.
