Lid, downlink strong jamming and uplink strong jamming.
In some embodiments, low switching success is analyzed by the measurement report of low switching success rate cell in step S303
The step of covering state of rate cell, can specifically include：
The cell that Reference Signal Received Power RSRP values in measurement report are less than default RSRP threshold values is obtained, is less than default
RSRP threshold values cell quantity and low switching success rate cell quantity ratio be more than the first ratio thresholding, low switching
The covering state of success rate cell is the weak covering of downlink.
The cell that user equipment uplink power margin PHR values in measurement report are less than default PHR threshold values is obtained, is less than pre-
If the ratio of the quantity of the cell of PHR threshold values and the quantity of low switching success rate cell is more than the second ratio thresholding, low switching
The covering state of success rate cell is the weak covering of uplink.
The cell that Reference Signal Received Quality RSRQ values in measurement report are less than default RSRQ threshold values is obtained, is less than default
The ratio of the quantity of the cell of RSRQ threshold values and the quantity of low switching success rate cell is more than third ratio thresholding, and undercut changes into
The covering state of power cell is downlink strong jamming.
The cell that uplink interference plus noise in measurement report is less than default SINR threshold values than SINR value is obtained, is less than default
The ratio of the quantity of the cell of SINR threshold values and the quantity of low switching success rate cell is more than the 4th ratio thresholding, and undercut changes into
The covering state of power cell is uplink strong jamming.
Ratio less than the quantity and the quantity of low switching success rate cell of the cell of default RSRP threshold values is less than or equal to
First ratio thresholding is less than less than the ratio of the quantity and the quantity of low switching success rate cell of the cell of default PHR threshold values
The ratio of the quantity of cell equal to the second ratio thresholding, less than default RSRQ threshold values and the quantity of low switching success rate cell
The quantity of quantity and low switching success rate cell less than or equal to third ratio thresholding and less than the cell of default SINR threshold values
Ratio be less than or equal to the 4th ratio thresholding, the covering state of low switching success rate cell is normal condition.

The first ratio threshold value when, the covering state of low switching success rate cell is the weak covering of downlink.In this example, RSRP is preset
Threshold value can be -110dBm, and the first ratio threshold value for example can be 10%.
As an example, user equipment uplink power margin PHR values are less than the cell for presetting PHR threshold values in MR reports
When sampled point accounting is more than the second ratio thresholding of setting, the covering state of low switching success rate cell is the weak covering of uplink.
In the example, it can be 3dB to preset PHR threshold values, and the second ratio threshold value for example can be 10%.
As an example, RSRQ values are less than the cell sampled point accounting of default RSRQ threshold values more than setting in MR reports
Third ratio thresholding when, the covering state of low switching success rate cell is downlink strong jamming.In this example, RSRQ are preset
Limit value can be -16dB, and third ratio threshold value for example can be 10%.
As an example, upstream sinr value is more than less than the cell sampled point accounting of default SINR threshold values in MR reports
When the 4th ratio thresholding being arranged, the covering state of low switching success rate cell is uplink strong jamming.In this example, it presets
SINR threshold values can be 3dB, and the 4th ratio thresholding for example can be 10%.
In some embodiments, the step of adjusting wireless switching timer based on covering state in step S303 specifically can be with
Including：
When covering state is normal condition, increase the setting value of wireless switching timer；Covering state is the weak covering of downlink
Or when downlink strong jamming, increase the setting value of wireless switching timer；When covering state is the weak covering of uplink or uplink strong jamming,
Reduce the setting value of wireless switching timer.
In this embodiment, if MPS process state is to switch time-out in the case of normal condition, judge possibility
It is that switching timer setting value is too small to cause, therefore the setting value of switching timer can be increased.
If there is uplink, such as covering state for the weak covering of uplink or uplink strong jamming, then in MPS process state
Think switching overtime to cause to switch unsuccessful to be since EnodeB fails to receive the uplinks switchings such as the random access of UE transmissions in time
Signaling causes to eat dishes without rice or wine to provide at this time if the invalid switching number of attempt of UE may be increased instead by increasing switching timer setting value
The waste in source, therefore can reduce or maintain switching timer setting value.
If there is downlink in MPS process state, then it is assumed that it is since UE fails that switching overtime, which causes to switch unsuccessful,
The downlink hand off signaling of EnodeB transmissions is received in time, at this time if UE successful receptions can be increased by increasing switching timer setting value
The probability of downlink hand off signaling, to improve handover success rate, it is therefore proposed that increasing switching timer setting value.
In some embodiments, after being optimized and revised to switching timer, by a test period, webmaster can be passed through
Front and back handover success rate situation is optimized and revised in the comparison of KPI statistical data, and since the unsuccessful rate of switching caused by time-out accounts for
Than thus verifying the effect of switching timer optimal design-aside.
In further embodiments, can take repeatedly it is above-mentioned optimize and revise step, tune is optimized to switching timer
It is whole, until effect of optimization is optimal.
