Estudio de la factibilidad técnica para la implementación de la tecnología Wi-Fi Calling en una operadora de la ciudad de Quito

Abstract

In the present degree work a study is made about the technical feasibility for the implementation of the service of Wi-Fi Calling in a cellular operator of the city of Quito. Wi-Fi Calling is a service that can be offered by cell phone companies, which enables users to make voice calls, and even send text messages from their smartphones using a Wi-Fi network instead of the traditional telephone connection. Allowing an extension of the cellular coverage signal, in places where the signal levels are not adequate for the call to be carried out normally. Determine the technical requirements necessary to implement Wi-Fi Calling in an operator, where the process of making a Voice over LTE call is analyzed. It is determined in which section of the EPC backbone network the changes must be made for Wi-Fi Calling to function correctly. Subsequently, a proposal is made for the implementation of Wi-Fi Calling in a mobile operator in the city of Quito. The results obtained in the feasibility study are analyzed and compared with other solution alternatives other than Wi-Fi Calling.
