Technical Field

Background
Mobility management is an important attribute of a mobile communication system, and handover is the key content of mobility management, so that reasonable handover behavior can reduce the overhead of the system for realizing mobility.
In the LTE (Long Term Evolution ) system, the state of a UE (User Equipment) can be divided into two states, i.e., a connected state and an idle state. When the UE in the connected state moves from the serving cell to another cell, a handover (handover) is triggered to ensure continuity of the service.
Since one cell has a plurality of neighbor cells when a network communication environment is set up in time. However, when a cell is switched, the misconfiguration of the values of certain configuration parameters causes the switching to and fro between two cells, namely the ping-pong switching effect. Ping-pong handoff also occurs when the service ranges of two base stations overlap and the signal quality of the two base stations varies strongly. When the ping-pong switching effect occurs, only the reasons can be searched manually and the configuration parameters can be modified to restrain the ping-pong switching, which is time-consuming and labor-consuming.
Aiming at the problem of lower suppression efficiency of ping-pong switching events in the related art, no effective solution is proposed at present.
