Control message receiving unit is measured, control message is measured for receiving, is carried in the measurement control message and require terminal
Measure and send the information of its translational speed；
Reporting message transmitting element, disappears for periodically sending to report according to predetermined period according to the measurement control message
Breath, the translational speed for making to carry in the reporting message that base station sends according to all terminals received count counterpart terminal quantity
The first most translational speed class, and institute is obtained according to the correspondence of pre-set translational speed class and switching condition
State the corresponding handoff threshold value of the first translational speed class and terminal, the reporting message are sent it to after the handover trigger time
In carry the translational speed of terminal；
Second receiving unit, for receiving handoff threshold value and handover trigger time；
Measurement report transmitting element, for according to the handoff threshold value and handover trigger time, in the RSRP parameters measured or
When RSRQ parameters exceed the handoff threshold value, record is in the time of the state more than handoff threshold value, and more than switching
When the time of the state of threshold value exceedes the handover trigger time, measurement report is sent to base station, carry in the measurement report into
Parameter needed for the switching of row cell；
Second switch unit includes：
3rd receiving unit, for receiving cell handover command；
Second switching subelement, the cell handover command for being received according to the receiving subelement complete cell switching.
A kind of 13. cell handover system, it is characterised in that the system comprises：
Base station, at least one terminal as in claim 12 as described in any one of claim 7-11.
