Analysis of the Application current X2 Interface Handover Process in LTE Technology

Abstract

LTE (Long Term Evolution) is a 4G technology which is in the developmental period. In its development we need to know the integrity of LTE networks in providing reliable service of the mobility when service users, so we need to discuss the handover process that occurs in LTE, where this handover process will determine the ability of communication networks in maintining the communication link is going. Problems arise when we talk handover is how the data transfer process occurs in LTE. X2 is an interface that must be passed whentheprocess of transferring data of time of handover between two eNodeB adjacentpieces in LTE. The capabilities of interface X2 also makes effect to maximization of the function on handover process, so it is necessary to analyze the function of interface X2 when handover happen between eNodeB in LTE. This research can be seen that the LTE quaranteering handover process when through on X2 interface at high speed that is greater than 60 km/hour. The existence makes use of the time required to performs faster handovers, seen from simulation result with TTT = 0,034 ms , Hom = 2,029 dB and TTD = 0,165 ms at speed 200 km/hour and angle direction of movement of user is 00 dan 600 . In addition , the faster movement of the user, the smaller the time required to perform handovers because the user through the area or areas slices cell or cell handovers
