An Improved Call Routing Framework for Mobile Number Portability in Nigeria

Call routing is a call management feature where each incoming call is placed in a queue and is then routed to a specific person or group of people based on pre-established rules and criteria. Call routing issues occurs when incoming calls do not reach the appropriate agent because of technical or configuration issues. This work aims at improving call routing framework for mobile number portability in Nigeria. A mobile number portability mathematical predictive model was developed to determine the routing of both originating and received calls. The model was used to create figures of the donor network and Recipient network during mobile number portability (MNP) in MATLAB using number of nodes The performance of the model was evaluated through the result of the analysis. The result shows how a mobile user A with Mobile Station International Subscriber Directory Numbers (MSISDN) 08130721624 operating on a donor network ported to a recipient network B. The research succeeded in solving the setbacks of poor quality of service common in our networks due to incompetent techniques of routing calls to called numbers. This has thus opened other research questions or perspective in academic environments and other research fields.
