ABSTRAKSI: Teknologi telekomunikasi telah berkembang dengan pesat bukan hanya untuk suara (voice), gambar (video), tetapi juga data dengan mobilitas yang tinggi. Mobilitas user yang mengakibatkan perubahan yang dinamis terhadap kualitas jaringan menuntut kontinuitas layanan pada jaringan telekomunikasi tetap terjaga, oleh sebab itu dibutuhkan mekanisme handover yang handal yang diharapkan dapat meningkatkan performansi jaringan. handover merupakan aspek yang penting dalam system radio seluler untuk memastikan hubungan yang tidak terjalin akan tetap terjaga meskipun user berpindah posisi. Handover tidak hanya terjadi pada sistem atau teknologi yang sama, tetapi memungkinkan terjadi pada sistem yang berbeda yang disebut intersystem handover.
Dalam tugas akhir ini di lakukan analisis terhadap mekanisme proses handover dari HSDPA ke LTE berdasarkan pergerakan user. Parameter yang dipergunakan pada analisis proses intersystem Handover HSDPA ke LTE adalah RSCPmin, RSRPmin, Handover Margin, Time-to-Trigger, probabilitas dropping pada intersystem Handover.
Hasil analisis dari simulasi yang telah dilakukan, didapatkan Received Signal Strength pada user yaitu nilai RSRP yang baik berdasarkan probabilitas dropping yang paling minimum antar HSDPA dan LTE dalam rangka mendukung pengembangan LTE. Dari hasil analisis simulasi didapatkan nilai RSRPmin berdasarkan probabilitas droping yang paling minimum dengan parameter Handover Margin = 2 dB, TTT = 0.4 s yaitu ketika RSCPmin = -95 dBm maka RSRP = -99 dBm; RSCPmin = -96 dBm maka RSRP = -101 dBm, RSCPmin = -97 dBm maka RSRP = -98 dBm, RSCPmin = -98 dBm maka RSRP = -98 dBm;= RSCPmin = -99 dBm maka RSRP = -98 dBm; RSCPmin - 100 dBm maka RSRP = -98 dBm

User mobility causes dynamic changes of network quality requires maintained continuity of services in telecommunications networks , and therefore needed a reliable Handover mechanism which is expected to improve network performance. Handover is an important aspect in cellular radio systems to ensure the relationship which is established will always held even if user moves from its position. Handover is not only happening in the systems with similar technology, but also in a different system called intersystem Handovers.
In this final project is done an analysis on mechanism process intersystem handover from hsdpa to lte based on user movement. Parameters used on analysis process intersystem handover hsdpa to let are RSCPmin, RSRPmin, Handover Margin, Time-to-Trigger, dropping probabily on intersystem Handover.
The results of the simulation analysis has been done, was found Received Signal Strength in a user which is a good value of RSRP based on the minimum dropping probability between HSDPA and LTE in order to support the development of LTE. From the simulation analysis results obtained RSRPmin value based on the minimum droping probability with the parameters handover margin = 2 dB, TTT = 0.4 s when RSCPmin = -95 dBm then RSRP = -99 dBm; RSCPmin = -96 dBm then RSRP = -101 dBm, RSCPmin = -97 dBm then RSRP = -98 dBm, RSCPmin = -98 dBm then RSRP = -98 dBm; = RSCPmin = -99 dBm then RSRP = -99 dBm; RSCPmin - 100 dBm then RSRP = -98 dBm.
