Analysis on Telephony Signalling System (ITU-T No.7) to Improve ILD/NLD Network Performance

K.Rajasri, M.Manimozhi, S.Sangeetha

In this paper we propose and develop the program for analysing the call failure in telecommunication network. Call failure analysis done through the SS7 signalling protocols. Presently there is no tool to analyse these protocols. Because everything is done manually with huge investment of time. To avoid this, a protocol is designed using NS2. The obtained text format of call failure is given to the protocol through which reason for call failure can be easily identified.
