Solution introduces the cell switching method below by taking cell switching method provided in an embodiment of the present invention is applied to mobile phone as an example.
As shown in Fig. 2, the embodiment of the present invention provides a kind of cell switching method, which may include following
Step 201 to step 203.
Step 201, terminal device, will be each in current scene and target switching script when carrying out cell handover measurement
Scene is matched.
It wherein, include at least one handoff scenario in target switching script, each at least one described scene
The handoff error rate of scene is all larger than or is equal to preset threshold.
Specifically, terminal device progress cell handover measurement is are as follows: signal quality and neighbour of the terminal device to current area
The signal quality of cell measures, and the measuring configuration (Measurement based on measurement result and server cell
Configuration parameter), it is determined whether to network side equipment reporting measurement reports (Measurement Report).
It is obtained in addition, the target switching script in above-described embodiment can be carried out big data statistics by terminal device, it can also
It is obtained with carrying out big data statistics by server, is then set being sent to terminal by the link between terminal device and server
It is standby.
In above-mentioned steps 201, if do not have at least one described scene scene matched with current scene (serving cell,
In the parameter of adjacent cell and measuring configuration to one mismatch), then terminal device directly carry out carry out cell handover measurement,
And event (Event) information sent based on measurement result to serving cell, last triggering terminal device carry out cell switching, and
If the serving cell of the current scene and the serving cell of target scene in target switching script are identical, described current
The adjacent cell of scene is identical as the adjacent cell of the target scene, and the parameter of the measuring configuration of the current scene and the mesh
The parameter for marking the measuring configuration of scene is identical, then executes following steps 202.
Step 202, terminal device obtain corrected parameter according to the target scene.
It should be noted that corrected parameter in above-mentioned steps 202 can for the parameter to a measuring configuration into
The modified parameter of row, or the parameter that the parameter to a measuring configuration is modified.
Illustratively, corrected parameter can be able to be to be modified to the triggered time (Time To Trigger, TTT)
Parameter, such as: TTT shortens 20 milliseconds；Corrected parameter may be specific frequency offset (the offset of to adjacent cell
The neighbour cell, Ocn) parameter that is modified, such as: Ocn reduces 1dB；Corrected parameter may be to TTT with
And the parameter that Ocn is modified, such as: Ocn is reduced into 1dB and TTT is shortened 20 milliseconds.
Step 203, terminal device are repaired based on parameter of the corrected parameter to the measuring configuration of the current scene
After just, cell handover measurement is carried out.
That is, then carrying out cell again after being first modified based on parameter of the corrected parameter to the measuring configuration of current scene
Handover measurement.
Cell switching method provided in an embodiment of the present invention, when carrying out cell handover measurement, first by current scene with
Each scene in target switching script is matched, if in the serving cell of the current scene and target switching script
Target scene identical, the described current scene of serving cell adjacent cell it is identical as the adjacent cell of the target scene, and institute
The parameter for stating the measuring configuration of current scene is identical as the parameter of the measuring configuration of the target scene, then according to the target field
Scape obtains corrected parameter, after being finally modified based on parameter of the corrected parameter to the measuring configuration of the current scene,
Carry out cell handover measurement, wherein the handoff error rate that target switches each scene at least one scene in script is equal
More than or equal to preset threshold, that is, the embodiment of the present invention can be greater than or equal to default threshold in the handoff error rate of current scene
When value, corrected parameter is obtained according to target scene, and based on the corrected parameter to the ginseng of the measuring configuration of the current scene
After number is modified, cell handover measurement is carried out, therefore the embodiment of the present invention can be greater than in the handoff error rate of current scene
Or when being equal to preset threshold, the parameter of the measuring configuration of current scene is modified, so that the generation for reducing handoff error is general
Rate, thus the embodiment of the present invention can solve the parameter setting of the measuring configuration of serving cell it is inappropriate when, terminal device exists
The probability of happening of handoff error larger problem when cell switches.
Under be described in detail with the implementation to cell switching method provided by the above embodiment.
Implementation one,
Referring to shown in Fig. 3, cell switching method provided in an embodiment of the present invention includes the following steps 301 to step 306.
Step 301, server obtain target and switch script.
Wherein, the target switching script includes at least one scene, each scene at least one described scene
Handoff error rate is all larger than or is equal to preset threshold.
Specifically, server can be obtained under each scene by the switch data that terminal device reports, handover success is gone through
The number and probability, too late of the number and probability of historical event part, too early switching (Too Early Handover) history of errors event
The number of (Too Late Handover) the history of errors event of switching and probability and it is switched to wrong cell (Wrong Cell
Handover) the number and probability of historical events, and be screened out from it handoff error rate (too early handoff error historical events it is general
Rate+probability of handoff error historical events too late+is switched to the probability of wrong cell historical events) it is greater than or equal to preset threshold
Scene obtain target switching script.
Further, the implementation that server obtains target switching script may include the following two kinds mode:
Mode 1,
The radio resource control information that multiple terminal devices are crossed to server undecoded (Decode), server pass through parsing
Radio resource control information simultaneously calculates the number and probability for switching successfully number and probability and various handover failures.
Mode 2,
Multiple terminal devices voluntarily decode and analyze radio resource control information, sum up itself handover success number with
Then the number and probability of various handover failure numbers and probability and various handover failures will analyze result upload server.
Illustratively, the scene in target switching script can be as follows:
Scene X,
● serving cell: SC001；
● target adjacent section: TNC002；
● the parameter of measuring configuration:
■ TTT001
■ offsetFreq/offsetMO 001

■ Hysteresis 001
■ ……
● result
The switching of ■ mistake:
Number X, probability Y%.
Further alternative, the target switches script further include: pair of each scene at least one described scene
The corrected parameter answered.
When target switches script further include: at least one described scene when the corresponding corrected parameter of each scene,
The scene that target switches in script can be as follows:
Scene Y,
● serving cell: SC001；
● target adjacent section: TNC002；

In addition, above-mentioned corrected parameter is specifically as follows the cloud that Cloud Server provides and builds when server is Cloud Server
Discuss interim antidote (Cloud Suggested TempCure 001).
Further alternative, the target switches script further include: each scene is corresponding at least one described scene
Error event.
Wherein, wherein the error event include: too early handoff error, too late handoff error and be switched to mistake it is small
At least one of area's mistake.
When target switches script further include: at least one described scene when the corresponding error event of each scene, mesh
Scene in mark switching script can be as follows:
