Participate in drafting of the technical specification in a tender.
Planning and Designing of the network
Life Cycle of the Software Management (i.e. software quality).
Implementation of projects
End to end testing of VoLTE or Fixed IMS network integration with Enterprise networks.The task requires IP tracing in a complex network and multi-protocol analysis
To understand customer requirements and realise it as technical requirements and implement it in the network
Conduct analysis of proper call flow requests, responses and/or updates using Tracing tools to capture SIP, TCP, UDP and other LTE-EPC and IMS Protocols
Conduct analysis of Telephony voice services to include call waiting, call barring, 3-way calling, etc.
Analyse the proper operation with PSTN (landline) and PLMN (mobile networks)
Verify proper operation of handsets in providing the Voice Services
Type approval of new interfaces, protocols and inter-working with 3 rd party system or new systems
Design and implement tools and applications to facilitate testing and workflow improvement
Degree/Masters in Engineering or Computer Science
Minimum 5 years’ relevant experience in the following aspects:
Mobility, LTE, Wireless Mobility Network Experience Domain and IMS architecture
SIP protocol and IMS based services
Protocol Specifications and Analysis
SS7 tracing, ability to discuss, identify and name the nodes in a typical SIP call flow and the nodes in an IMS/Application Server platforms and the function of each note.This includes validation with architects to ensure the correct call flow, clearly and accurately document and discuss the discrepancies, anomalies or issues with the test case
Packet Analysis for VoLTE (or VOIP) Protocols Wireless domain of LTE, 3G, 3G+PacketCore, /UMTS/LTE
Analyze inter- operation with 3,4, and 5 networks For example handover between any of the applicable network types
LTE, UMTS and GSM/GPRS Call flows
Network topology & various interfaces
Protocol testing of UMTS/LTE
Understanding of call processes between End to End system testing
