A Seamless Multi-link Switch Solution for LTE and Wi-Fi Integrated Networks

Abstract

Today, smart mobile devices drive the mobile traffic growth rapidly. The Integration of multiple radio access technologies is a viable solution for mobile operators to fulfill users' data usage. In this paper, we consider the inter work issue for the LTE and Wi-Fi integration network. Based on the GPRS Tunneling Protocol (GTP), a multi-link switch approach is proposed to solve the seamless handover and cooperating issues between LTE and Wi-Fi networks. The performance results show that the average switch delay is slight, which is efficient to support most of real-time application services, such as VOIP service and interactive games.
