Network Management Equipment is after being set to the receiving sensitivity of UE by initial for base station equipment corresponding q-RxLevMin, and as shown in Figure 1, the defining method of this cell parameter comprises the following steps:
Step 101, Network Management Equipment obtains RSRP value corresponding to base station equipment.
In the embodiment of the present invention, Network Management Equipment obtains RSRP value corresponding to base station equipment, specifically comprises:
Steps A, Network Management Equipment receive the MR(Measurement Report from base station equipment, measurement report), carry UE in this measurement report and measure and the RSRP value reporting base station equipment.
Wherein, base station equipment periodically can report to Network Management Equipment the measurement report carrying RSRP value, and Network Management Equipment periodically can receive the measurement report carrying RSRP value from base station equipment.Such as, base station equipment reports every 15 points of clockwise Network Management Equipments the measurement report carrying RSRP value, and based on this, namely Network Management Equipment can receive the measurement report carrying RSRP value from base station equipment every 15 minutes.
RSRP value when step B, Network Management Equipment select power headroom to be 0 from measurement report; Wherein, RSRP value when power headroom is 0 is the RSRP value of UE under maximum transmission power.
Concrete, Network Management Equipment receive from base station equipment carry the measurement report of RSRP value after, RSRP value when periodicity selects power headroom to be 0 from this measurement report.If Network Management Equipment is every the integral multiple of 15 minutes or 15 minutes, RSRP value when selecting power headroom to be 0 from measurement report.
In the embodiment of the present invention, based on the measurement report from base station equipment, two dimensional pointer is measured to need that Network Management Equipment is supported, Network Management Equipment is supported, and the two-dimensional measurement amount of power headroom and RSRP value is added up.Based on this, Network Management Equipment receive from base station equipment carry the measurement report of RSRP value after, the RSRP value corresponding to often kind of power headroom can be known, then can know RSRP value when power headroom is 0.
Step C, Network Management Equipment carry out ascending sequence to the RSRP value selected.
Concrete, after RSRP value when Network Management Equipment selects power headroom to be 0 from measurement report, RSRP value when being 0 by these power headroom carries out ascending sequence.
Step D, Network Management Equipment choose N number of RSRP value as RSRP value corresponding to base station equipment.
In the embodiment of the present invention, the determination mode of N specifically includes but not limited to: when (the quantity * y% of the RSRP value of selection) is positive integer, and Network Management Equipment determines that the value of N is (the quantity * y% of the RSRP value of selection); When (the quantity * y% of the RSRP value of selection) is not positive integer, Network Management Equipment determines that the value of N is for being less than first positive integer of (the quantity * y% of the RSRP value of selection).
Such as, suppose y=5, when the quantity of the RSRP value when the power headroom selected from measurement report is 0 is 60, then (the quantity * y% of the RSRP value of selection)=3, now Network Management Equipment determines that the value of N is 3, and chooses the 3rd RSRP value (the 3rd RSRP value namely after ascending sequence) as RSRP value corresponding to base station equipment; When the quantity of the RSRP value when the power headroom selected from measurement report is 0 is 50, then (the quantity * y% of the RSRP value of selection)=2.5, now Network Management Equipment determines that the value of N is first positive integer that namely 2(is less than 2.5), and choose the 2nd RSRP value (the 2nd RSRP value namely after ascending sequence) as RSRP value corresponding to base station equipment.
