Abstract :
To improve the interworking between LTE and WiFi wireless technologies, an efficient handover mechanism is proposed. Dynamic and critical measures like mobile-assisted parameters are inserted to the Access Network Discovery and Selection Function (ANDSF) entity defined by 3GPP standard. Moreover, Context Aware (CA) decision algorithm is integrated within the ANDSF server so that the inserted measurements are expeditiously invested to improve the handover decision policy. The performance enhancement of the proposed model compared to the traditional one is shown by numerical simulations.
