Mark in cell.
The bit error rate that Target cell decoded to the signal on high speed interface-free resources channel is judged according to measurement report, when
When the bit error rate of Target cell decoding is less than the default bit error rate, the Radio Link of current area is discharged, completes current area to mesh
Mark the baton handover on the physical channel of cell.Wherein, it is the default a certain absolute value of operator to preset the bit error rate, or is current
The bit error rate that cell decodes in high speed interface-free resources.
In the technical scheme of the present embodiment, the measurement report that cell baton handover device reports according to terminal judges terminal
Mobile status, if terminal is in high-speed moving state, the Target cell of terminal switching is further determined that, if terminal is at a high speed
Mobile status, Target cell are the cell associated under virtual subdistrict, it indicates that Target cell enables the monitoring of high speed interface-free resources should
Decoded signal on channel, judges whether the absolute value of the Target cell bit error rate is more than the default bit error rate, if then by the terminal
Switch in Target cell.Because the physical channel resources of terminal are distributed in current area, terminal is distributed to Target cell
Physical channel resources are identical, therefore terminal is always positioned at carrying out communications, bottom on same channel before the handover and after switching
Transmission does not switch, and reduce minizone frequent switching influences to caused by terminal data communication quality.Simultaneously for target
The calculating of the synchronizing process of cell mainly carries out calculating judgement by the cell baton handover device of network side, and virtual subdistrict is pre-
It is identical to define the high speed interface-free resources of all associated cells, substantially reduces terminal switch decision duration so that in GSM network
