Enterprise LTE and WiFi interworking system and a proposed network selection solution

With a bandwidth reservation mechanism, we propose that LTE can assist existing WiFi networks to improve the Quality of Experience (QoE) of wireless communication in enterprise and meanwhile increase the available spectrum. To address the associated network selection problem between WiFi and LTE, in this paper based on the 3GPP standard Access Network Discovery and Selection Function (ANDSF) framework, a context-aware solution named Extended Dynamic Enterprise ANDSF (EDE-ANDSF) is presented. It can select interfaces according to real time network conditions and cater for specific enterprise requirements.
