Abstract: Heterogeneous handover always had been a challenge for seamless roaming. Security aspects like authentication and re-authentication is a key factor in providing seamless connectivity. Self Organizing Network (SON), an innovative intelligent network management system proposed by 3G Partnership Project (3GPP) enhances the best possibility of Inter-Rat handover and security re-authentication by using advanced mobility management procedures. A novel SON based simple light-weight seamless handover Rapid Re-authentication Protocol (3SH_RRP) is proposed in this study. This protocol provides fast seamless handover using Cloud RAN architecture based deployment. It provides a rapid re-authentication within Cloud RAN with the help of Virtual Homing (VH) concept in SON. 3SH_RRP is implemented in SON which gives better results as it eliminates involvement of too many network elements causing severe processing overhead and multilevel communications. This protocol uses log likelihood weighted factor (Bandwidth, Security level, Power Level and Received Signal Strength Indicator) function to maximize the probability of successfully selecting the most appropriate BBU well in advance to perform super-fast or rapid re_authentication during inter_RAT HO. This Work helps service provider to offer spectrum efficient distribution of services. It aims at supporting future bandwidth and delay sensitive applications like high definition digital TV broadcast, telepresence and other multimedia applications by with-holding fairer usage to other services like voice and low bandwidth internet data. Simulation was implemented using OMNET++ with Simu-LTE network simulation package. Experimental results have shown that multi-media serviced user was able to seamlessly connect to networks with low latency and improved quality of service. The proposed algorithm has shown better results with higher transition rate, lower delay upto 300km/¯1 h fast mobility of user equipment.
