Nokia Corp. Software Developer/Engineer

Designed, developed, debugged, and tested object-oriented VoIP softswitch call processing control and voice transcoding systems for Nokia IP Telephony carrier-grade systems providing Signalling Gateway (SG), Media Gateway (MG), Media Gateway Controller (MGC), and Call Processing Server (CPS), Call Agent, Gatekeeper services in Java, C++ using SS7, SIP, IBM Rational Rose/RealTime, and ClearCase.

Designed, developed the Media Gateway Controller (MGC). MGC resides between the Media Gateway, the signalling Gateway and the Call Processing Server/Gatekeeper. It provides the call processing (call handling) function for the Gateway. It controls the Media Gateways; it receives PSTN signalling information from the Signaling Gateway and IP signalling from the Call Processing Server/Gatekeeper. An MGC handles the registration and management of the resources at the Media Gateway. The MGC may have the ability to authorize resource usage based on local policy. For signalling transport purposes, the MGC serves as a possible termination and origination point for PSTN application protocols, such as SS7 ISDN User Part Q.931/DDS1.Media Gateway Controller (MGC) communicates to the Call Processing Server (CPS) using Q.931 and H.323.

Designed, developed, tested, debugged, and troubleshot the Nokia VoIP MGC finite state machine (FSM). The Media Gateway Controller (MGC) state machine (FSM) consists of 9 states and 23 events (transitions). The Media Gateway Controller is a software application written in C++ and composed of 3 components: a (1) CPI (Call Processing Interface), a (2) SGI (Signalling Gateway Interface); and a (3) MGI (Media Gateway Interface).

Designed, developed, tested and integrated real-time embedded middleware framework applications for Nokia IP Telephony softswitch using the ACE (Adaptive Communication Environment) providing concurrency, thread management, interprocess communications, shared memory in C++ on WindRiver VxWorks/Windows host and MPC8260 PowerPC board support package (BSP) target.

Designed, planned, implemented, authored a R&D research study of voice over IP (VoIP) Quality of Service (QoS) and IP traffic engineering using MPLS, routing protocol using IGP (link-state: OSPF, IS-IS, distance-vector: RIP, E/IGRP); EGP (path-vector: BGP), traffic shaping and management for Nokia VoIP telephony systems platform.
