Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts Embodiment shall fall within the protection scope of the present invention.
It is that a kind of flow of the carrier wave measurement method based on unauthorized frequency range provided in an embodiment of the present invention is shown referring to Fig. 1 It is intended to, in embodiments of the present invention, the method includes：
If the ratio that CQI is less than the user equipment of default CQI thresholdings in S101, cell is more than preset value, the base station inspection Survey the disturbed condition of the corresponding operating carriers of the cell.
Wherein, the base station of the embodiment of the present invention and user equipment are operated in the cell of unauthorized frequency range, i.e. cell is corresponding Carrier wave is that operating carriers are the currently used carrier wave of the cell belonging to base station.Multiple user equipmenies in cell can each self feed back The CQI (Channel Quality Indicator, channel quality instruction, abbreviation CQI) of up channel, base station is in preset duration It is interior to receive the CQI of multiple user equipment feedbacks, and the CQI received and default CQI thresholdings are compared, determine that CQI is less than The quantity of the user equipment of default CQI thresholdings is calculated and is used in the quantity and cell for the user equipment that CQI is less than default CQI thresholdings The ratio of the quantity of family equipment, if the ratio being calculated is more than preset value, the corresponding operating carriers of cell are detected in base station Disturbed condition, whether to determine operating carriers by strong jamming, if being shown that the operating carriers of base station may need by strong jamming It switches over.
If S102, the operating carriers, by strong jamming, multiple user equipmenies of the base station into the cell, which are sent, to be carried Wave measurement indicates that the carrier wave, which measures, indicates that being used to indicate the multiple user equipment measures corresponding operating carriers RSSI, and the RSSI obtained to the base station return measurement.
Specifically, if operating carriers are by strong jamming, multiple user equipmenies of the base station into cell send carrier wave and measure Instruction, wherein carrier wave are measured to indicate can be used and be sent by the carrier wave of authorized spectrum band or the carrier wave of unauthorized frequency range, such as：It is logical It crosses scheduling information or RRC (Radio Resource Control, wireless heterogeneous networks, abbreviation RRC) signaling is carried.Carrier wave Multiple user equipmenies that instruction is sent in cell are measured, multiple user equipmenies are in the user equipment of connected state, each user Equipment is received after carrier wave measures instruction and is measured to corresponding operating carriers, to obtain the RSSI of operating carriers (Received Signal Strength Indicator, received signal strength indicator, abbreviation RSSI), and respectively returned to base station Return the RSSI for measuring and obtaining.

Wherein, the duration of preset duration and measurement in preset duration are herein, the time interval present invention do not limit System, can be configured as needed.
S205, it is measured without carrier wave.
S206, the base station obtain average RSSI after being averaged the RSSI repeatedly measured.
Specifically, the method present invention that obtained multiple RSSI are averaged is measured for more times of S204 not to be restricted, it can be with Simple arithmetic mean value, geometrical mean and weighted arithmetic average etc. are taken, can also be averaged using other methods.
Whether S207, the average RSSI are more than default RSSI threshold values.
Wherein, if the average RSSI that S206 is calculated is more than default RSSI threshold values, S208 is executed；If S206 is counted Obtained average RSSI is not more than default RSSI threshold values, executes S209.
S208, determine the corresponding operating carriers of the cell by strong jamming.
Wherein, base station determines that operating carriers by strong jamming, show that the service quality decline of business may influence business Be normally carried out, user equipment in indicating cell carries out carrier wave measurement, according to carrier measurements come further confirm that whether It needs to carry out carrier switch, to ensure the service quality of business.
S209, determine that the corresponding operating carriers of the cell are not affected by strong jamming.
S210, base station based on unauthorized carrier wave or authorize the scheduling information of carrier wave or RRC signaling more into the cell A user equipment sends carrier wave and measures instruction, and it is respectively right that the carrier wave measurement instruction user indicates that the multiple user equipment measures The RSSI for the operating carriers answered, and the RSSI obtained to the base station return measurement.
Wherein, each user equipment takes multiple measurements operating carriers in preset duration, takes what is repeatedly measured to be averaged Value returns to the RSSI after being averaged to base station, and detailed process is referred to the method that base station side measures average RSSI.
S211, feedback RSSI whether be more than the default RSSI threshold values.
Wherein, the size of the RSSI and default RSSI threshold values of the more each user equipment feedback in base station, if feedback RSSI is more than default RSSI threshold values, executes S213, otherwise executes S212.
S212, do not indicate that user equipment switches over.
S213, instruction user equipment switch over.
Wherein, base station determines to be switched target carrier, and mesh is carried to needing the user equipment for carrying out carrier switch to send The carrier switch standard of the frequency point and bandwidth of carrier wave is marked, which receives carrier switch instruction, current work is carried Wave is switched to target carrier.
Implement the embodiment of the present invention, the ratio for the user equipment that base station CQI in cell is less than default CQI, which is less than, to be preset When value, to itself measure operating carriers disturbed condition and intra-cell users device measuring operating carriers disturbed condition into Row assessment, to determine whether to carry out carrier switch.It thus is avoided that base station periodically carries out carrier wave measurement, is become from active detecting The passive detection of trigger-type reduces the processing expense of base station, while the accuracy of the carrier switch assessment improved.
