Abstract
This paper proposes an optimised method to supervise free roaming calls. Since November 28th, 2016, West African countries and members of the Economic Community of West African States (ECOWAS) have decided to ban roaming charges among mobile phone users in these countries. Its implementation however poses a problem of performance costs of their visibility for certain actors such as regulatory authorities (R.A.). To improve this matter we proposed to set up a SIP proxy (Session Initiation Protocol) at the regulatory authorities in order to recover only the signaling of received calls in roaming. The SIP proxy is implemented by Kamailio. Compared to the literature, this article brings a new method of supervision by controlling and following the evolution of calls received in roaming. The results obtained have produced positive effects as only concerned calls will be supervised through the proxy. The proposed solution will facilitate regulators to perform their duties as taxing operators and resolving conflicts between them. It will allow end-users to have visibility into their calls.
