| Sumario: | One of the objectives concerning fifth generation (5G) communication systems is tending to the growing amounts of user and the mobile data. The deployment of heterogeneous networks (HetNet) is an option to increase the capacity of these systems, but it also increases the amount of connection transfers (handovers), as well as the quantity of handover failures and ping-pong handovers. To reduce these failures, that deteriorate the network quality of service, a method is proposed in order to adapt the parameters that control the handover starting time, time-to-trigger (TTT) and handover-margin (HOM), based on the signal-to-interference-noise ratio (SINR). Numerical evaluations show a simultaneous reduction of the handover failure rate and the ping-pong handover rate for the proposed method with a perfect knowledge of future SINR) values, as opposed to a handover procedure with constant parameters, which presents a tradeoff among both failures. |
