Vertical Handover in Long Term Evaluation (LTE)

In mobile network the handover process is very important to allow the call continuation with high mobility. However the high handover rate increases the signaling load. In this paper a vertical handover in LTE (Long Term Evaluation) was proposed according to two scenarios, the first scenario initialize the handover according to the signals strength and the second scenario initialize the handover according to the costs optimization. A MAT LAB simulation code is written and the results of the two mechanisms are given.
