PCF is telecom network component in 5G network architecture to support unified policyframework, providing policy rules to CP functions, and access subscription information for policy decisions. This enhancement provided support to delete subscriber N7 session and associated N28 session from PCF, and database via Ops Center CLI (Command Line Interface).

Mediation Device and DC1812(Radius Probe) applications of MCng system communicate with each other to collect Radius data from Radius Server. Radius (Remote Authentication Dial-In User Service) is a networking protocol used by Internet Service Providers(ISPs). When user dial in to the ISP he must enter username and password. This information is passed to a RADIUS server, which checks that the information is correct, and then authorizes access to the ISP system. This project is developed to extract information from Radius packets and sends to LEA in ASN.1 format.

MCng(Monitoring Center next generation) application interacts with Huawei passive interception management system to collect telecom data like voice, sms, and fax from network for Lawful Interception. This implementation is done in Mediation Device (MDng) to set triggers/filters on Huawei system to collect data. Trigger states are managed in Mediation Device to mark active/inactive based on requirement for data capture. Data received from Huawei system is captured into MCng database for analysis in the form of intercepts.

Mediation Device (MDng) is one of the components of MCng (Monitoring Center next generation) works as a mediator between passive data collectors and MCng to capture live traffic fromtelecom network and forward to MCng. Radius Probe collector captures Radius protocol packets and extracts IP addresses, and send to Mediation Device, then Mediation Device creates/manages triggers/filters using these IP addresses on IQProbe collector which collects/captures IP based data. This implementation was done to enhance the capability of IQ Probe to capture IP packets/data routed through Delegated IPv6 addresses for interception in MCng.

Sovereign is a middleware application developed using REST service and Hibernate to servethe request of different channels requested for data by providing/consuming web Services to/of other applications, was used for cache. Earlier caches were implemented in Sovereign using JBoss Infinispan,in-memory distributed cache which stores data at local JBoss servers JVM, due to that memory consumption was getting increased. This project is aimed to migrate all caches from local JBoss infinispan to JBoss Datagrid (JDG) which stores data on another server and releases some memory overload from JBoss.

Description: Mediation Device application works as a Mediator to set triggers on frontend

application and receive IP data from network, and accumulate in the form of PCAP, then send to

another application for processing. Hazelcast cache is implemented to store metadata about

captured data to Hazelcast server in case of system failure, so stored PCAPs can be processed

again After MD application started.

Responsibilities: Involved in developing new module in MD for Hazelcast, which works as a server.
