Abstract
Since the number of user equipments has also increased rapidly, the problem of network load due to frequent handover of user equipments has occurred. As a solution to this we expect to be able to reduce network overload problems and the delay caused by handover using LTE-based D2D communication. In this paper, we proposed a proposal to support handover via a preceding user equipment using LTE-based D2D communication by handover method of existing LTE network. We proposed a method that can efficiently solve the handover situation of the user equipment via the preceding user equipment in order to reduce the overlapping signal used at the time of handover between the base station and the user equipment. The handover delay accompanying the change in the number of user equipments was able to confirm the result that the suggested scheme was reduced as compared with the existing LTE handover.
