Abstract

The invention discloses an LTE cell handover method based on a decision section. The LTE cell switching method comprises the following steps: step 1, calculating a handover failure rate; step 2, carrying out section correction; step 3, carrying out handoff decision; and step 4, figuring out an optimal cell. The LTE cell handover method disclosed by the invention is used for analyzing the handover failure rate index of a service cell, importing a correction factor of a section function and adaptively tracking the deterioration situation of cell handover performance, so as to dynamically switch hysteresis parameters for adjustment, improve the continuity of business development and guarantee the customer perception.

Description

technical field [0001] The present invention relates to a handover method of an LTE system, in particular to a decision interval-based LTE cell handover method that can better match the external environment, adaptively adjust handover parameters, and select a target serving cell according to evaluation criteria perceived by customers . Background technique [0002] By adopting multiple key technologies such as OFDM, SC-FDMA, and MIMO, LTE can significantly reduce the delay of the user plane and the control plane, achieve faster data rates than current 2 / 3G systems, and provide higher cell throughput. Similar to 2 / 3G mobile communication systems, handover is still one of the most common procedures in LTE. When the terminal moves between cells, the eNodeB may initiate a handover process based on a certain strategy to maintain the continuity of mobile communication and provide more users with guaranteed QoS (Quality of Service, Quality of Service) services.
