Cell, according to the cell ID of Target cell, if being switched to Target cell handover failure from first community, electronic device is from time
It selects and chooses the high candidate cell of preferential level in cell as Target cell, switched over to new Target cell, so repeated,
Until handover success.
Optionally, another that following method may include according to the progress cell switching of cell switching command：Electronic device according to
Cell ID in the multiple candidate cell obtains the multiple candidate cell current signal strength value；According to described current
Signal strength values determine the target switching priority of the multiple candidate cell；If the target switching priority and the reference
Switching priority is different, and the candidate cell of highest priority refers to switching priority with described in the target switching priority
The candidate cell of middle highest priority is different, then the mark of the Target cell is obtained according to the target switching priority；Root
According to the mark of the Target cell, the Target cell is switched to from first community.
Wherein, electronic device is receiving cell switching command, parses the multiple candidate cells carried in cell switching
Cell ID after, according to the cell ID of multiple candidate cells, it is small to obtain the candidate that the cell ID of candidate cell is characterized
Then area obtains the current signal strength value of multiple candidate cells.According to the cell ID of Target cell, if being cut from first community
Target cell handover failure is changed to, then it is small as target to choose the high candidate cell of preferential level from candidate cell for electronic device
Area is switched over to new Target cell, is so repeated, until handover success.
As can be seen that in this example, first where reporting speech quality evaluation parameter, electronic device to the network equipment is small
First signal strength values in area and the second signal intensity value of multiple second communities, second community are the neighbouring small of first community
Area, the network equipment are judged according to above-mentioned data by the first preset range switching condition and the second preset range switching condition
When electronic device needs to carry out cell switching, then candidate cell is determined from multiple second communities, and candidate cell is arranged
With reference to switching priority, different candidate cells has different reference switching priorities, and generates carrying and refer to priority mark
Know and the cell switching command of the cell ID of candidate cell is to electronic device, electronic device is according to reference to priority tag and time
It selects the cell ID of cell to carry out cell switching, with this, the generation for the case where speech quality declines after cell switches can be reduced,
The intelligent and reliability of cell switching can be also promoted simultaneously, meanwhile, electronic device can also be according to the cell mark of candidate cell
Know, obtain the signal strength values of candidate cell in real time, and generate target switching priority, and by target switching priority and joins
It examines switching priority to be compared, if the two is different, cell switching is executed using target switching priority, then can be promoted small
The efficiency of area's switching, and the generation for the case where speech quality reduces after cell switches is reduced to a certain extent.
