Macro base station can preset network coverage cavity thresholding, can be with after macro base station receives Radio Link Failure instruction
The cell signal strength that Radio Link Failure instruction carries is obtained, when cell signal strength is lower than network coverage cavity thresholding,
Macro base station determines that UE is in network coverage cavity, it is therefore desirable to rebuild communication link for UE, execute step S103；Work as cell signal
When intensity is higher than network coverage cavity thresholding, macro base station determines that the Radio Link Failure of UE is caused by other reasons, such as adjacent
Frequency interference, poor transmission of information frame etc., macro base station can execute step S106.
Wherein, the threshold value of network coverage cavity thresholding can be set by experience, be also possible to obtain through actual measurement.
Cell signal strength is with Reference Signal Received Power (Reference Signal Receiving Power, abbreviation RSRP)
Example, when RSRP is less than -85dBm, service call success rate is very low, and cutting off rate is higher, and network coverage cavity thresholding can be set
For -85dBm.
S103, macro base station send different-frequency measure configuration information to UE according to the cell ID of serving cell so that UE according to
Different-frequency measure configuration information measures adjacent cell；
Wherein, measurement configuration information includes object, cell list, the report manner, measurement mark, service that UE needs to measure

Sample place 2 measurement obtain cell signal strength be respectively actual measurement information 2 be (B (R4), C (R5), D (R6)), in sampling site
It is respectively (R7, R8, R9) that 3 measurement of point, which obtains cell signal strength, then actual measurement information 3 is (B (R7), C (R8), D (R9)),
It is as shown in table 1:
Table 1
It is in practical applications, similar to above-mentioned measurement process in the mode of other sampling positions measurement cell signal strength,
Details are not described herein again.
It should be noted that in practical applications, if not needing to determine some place in UE corresponding network covering cavity,
So actual measurement information can also save place, as shown in table 2:
| Actual measurement information | Cell B | Cell C | Cell D |
| Actual measurement information 1 | R1 | R2 | R3 |
| Actual measurement information 2 | R4 | R5 | R6 |
| Actual measurement information 3 | R7 | R8 | R9 |
| … | … | … | … |
| Actual measurement information n | Ri | Rj | Rk |
Table 2
S104, macro base station receive the actual measurement information that UE is sent；
Since UE can not be communicated with serving cell, after UE obtains actual measurement information, actual measurement information is sent out
Macro base station is given, macro base station can receive the actual measurement information of UE transmission.
Actual measurement information is sent to micro-base station by S105, macro base station.
Wherein, the micro-base station is corresponding with above-mentioned serving cell.Actual measurement information is sent to the micro-base station by macro base station, should
After micro-base station obtains actual measurement information, actual measurement information can be stored in local, and build according to actual measurement information
Vertical actual measurement information aggregate.
It is understood that macro base station can be sent by the period, or the mode sent immediately sends actual measurement information,
It is not construed as limiting herein.
S106, macro base station execute other processes.
When UE is not at network coverage cavity, macro base station can execute the carrier policy of default, can also execute it
His process.
Optionally, macro base station establishes actual measurement information aggregate according to actual measurement information, by actual measurement information aggregate
It is sent to micro-base station.
Specifically, after macro base station receives several actual measurement information from serving cell, it can be according to practical survey
Amount information establishes actual measurement information aggregate, then actual measurement information aggregate is sent to the micro-base station of above-mentioned serving cell, should
The actual measurement information aggregate is stored in local by micro-base station.
In embodiment illustrated in fig. 1 and alternative embodiment, micro-base station can be according to the actual measurement from network coverage cavity
Information establishes the corresponding actual measurement information aggregate in network coverage cavity.
Two, metrical information is obtained, actual measurement information in metrical information and actual measurement information aggregate is matched:
S201, micro-base station receive the metrical information that UE is reported, and metrical information includes the cell mark of three or more adjacent cells
Knowledge and cell signal strength；
In the present embodiment, micro-base station is corresponding with serving cell, and UE can measure the cell of adjacent cell in serving cell
Signal strength obtains metrical information, which is sent to micro-base station, micro-base station can receive the metrical information.The survey
Amount information includes the cell ID and cell signal strength of three or more adjacent cells, shown in the format and Fig. 1 of metrical information
Actual measurement information format in embodiment is similar, and details are not described herein again.
S202, micro-base station judge to match with the presence or absence of actual measurement information with metrical information in actual measurement information aggregate,
If it exists, S203 is thened follow the steps；
Wherein, actual measurement information refers to the measurement measured in network coverage cavity to above-mentioned adjacent cell
Information.Since the cell signal strength that each place of serving cell measures three or more adjacent cells is different, measurement letter
The place of breath and serving cell corresponds, and matches if there are actual measurement information in actual measurement information aggregate with metrical information
When, show that the present position UE is located at around the sampling position of the actual measurement information, the probability of UE call drop is very big, therefore UE needs
It is switched in the preferable adjacent cell of signal strength, occurs to avoid the case where call drop, execute step S203, if it does not exist, then
Show that the present position UE not within the scope of network coverage cavity, does not need to switch, can execute operator's default policy.
Micro-base station judges to match with the presence or absence of actual measurement information with metrical information in actual measurement information aggregate, specifically may be used
To include following implementations:
Micro-base station with actual measurement information each in actual measurement information aggregate respectively, as target actual measurement information, to sentence
In disconnected metrical information in each cell signal strength and target actual measurement information the difference of corresponding cell signal strength it is absolute
Value, if no more than corresponding default cell threshold, if so, determining that target actual measurement information is matched with metrical information.
Specifically, as obtained by metrical information and actual measurement information measure in serving cell, metrical information
It is same or similar with adjacent cell corresponding in actual measurement information.Micro-base station can believe measurement by adjacent cell mark
Breath is matched with actual measurement information, for example, according to cell B, cell C, cell D, by the cell signal strength of metrical information
It is compared with the cell signal strength of target actual measurement information, if difference is minimum, it is believed that metrical information and practical survey
It is identical to measure information, or very close, determines that target actual measurement information is matched with metrical information.Wherein, different adjacent cells pair
The default cell threshold answered may be the same or different.
For example, actual measurement information is as shown in table 2, and metrical information is (B (Rx), C (Ry), D (Rz)), and measurement is believed
Breath is compared with actual measurement information 1, and specific judgement is as follows:
If the difference of corresponding cell signal strength in each cell signal strength and actual measurement information 1 in metrical information
Absolute value, no more than corresponding default cell threshold, i.e. ︱ Rx-R1 ︱≤Y1；︱ Ry-R2 ︱≤Y2；︱ Rz-R3 ︱≤Y3；Three
A inequality is set up simultaneously, it is determined that metrical information is matched with actual measurement information 1；If ︱ Rx-R1 ︱≤Y1；︱ Ry-R2 ︱≤
Y2；︱ Rz-R3 ︱≤Y3；Three inequality are not set up simultaneously, it is determined that metrical information and actual measurement information 1 mismatch；Its
In, Y1 is the corresponding default cell threshold of cell B, and Y2 is the corresponding default cell threshold of cell C, and Y3 is that cell D is corresponding pre-
If cell threshold.
It should be noted that can also be compared without using absolute value, can also be compared using other calculations
