Embodiment one
Aiming at the problems existing in the prior art, the embodiment of the present invention one provides a kind of cell parameter (cell parameter tool
Body can be q-RxLevMin, and by cell parameter be q-RxLevMin for) determination method, Network Management Equipment (such as: OMC
(Operation and Maintenance Center, operation and maintenance center) etc.) receiving sensitivity of UE is utilized at the beginning
Base station equipment initially corresponding q-RxLevMin is set, i.e., by the base station equipment, initially corresponding q-RxLevMin is set as UE's
Receiving sensitivity, such as by the base station equipment, initially corresponding q-RxLevMin is set as -125dBm, i.e. q-RxLevMin's is initial
Value is -125dBm.For example, then Network Management Equipment can choose connecing for 4 UE when having 4 UE in the serving cell of base station equipment
The average value of sensitivity is received as the initial corresponding q-RxLevMin of the base station equipment；Alternatively, Network Management Equipment can choose minimum
UE receiving sensitivity as the initial corresponding q-RxLevMin of the base station equipment；Alternatively, Network Management Equipment can choose maximum
UE receiving sensitivity as the initial corresponding q-RxLevMin of the base station equipment；Details are not described herein for corresponding manner.
Later, the corresponding q-RxLevMin of base station equipment is sent to base station equipment (the i.e. service base of UE by Network Management Equipment
It stands)；And the corresponding q-RxLevMin of base station equipment is sent to UE by the base station equipment.Specifically, base station equipment can pass through

UE；Alternatively, base station equipment can also pass through SIB5(system information block 5) it will be corresponding to the q- of the adjacent cell of serving cell
RxLevMin is sent to UE.
Network Management Equipment is such as schemed after by base station equipment, initially corresponding q-RxLevMin is set as the receiving sensitivity of UE
Shown in 1, the determination method of the cell parameter the following steps are included:
Step 101, Network Management Equipment obtains the corresponding RSRP value of base station equipment.
In the embodiment of the present invention, Network Management Equipment obtains the corresponding RSRP value of base station equipment, specifically includes:
Step A, Network Management Equipment receives the MR(Measurement Report from base station equipment, measurement report), the survey
The RSRP value that UE is measured and is reported to base station equipment is carried in amount report.
Wherein, base station equipment can periodically report the measurement report for carrying RSRP value, and Network Management Equipment meeting to Network Management Equipment
Periodically receive the measurement report of the carrying RSRP value from base station equipment.For example, base station equipment was set every 15 minutes to network management
It is standby to report the measurement report for carrying RSRP value, it is based on this, Network Management Equipment can be received every 15 minutes from base station equipment
Carry the measurement report of RSRP value.
Step B, the RSRP value that Network Management Equipment selects power headroom from measurement report when being 0；Wherein, power headroom 0

RSRP value when to select power headroom in measurement report be 0.If Network Management Equipment was every 15 minutes or 15 minutes integral multiples, from survey
RSRP value when selecting the power headroom to be 0 in amount report.
In the embodiment of the present invention, based on the measurement report from base station equipment, need that Network Management Equipment is made to support two dimensional pointer
Measurement makes Network Management Equipment that the two-dimensional measurement amount of power headroom and RSRP value be supported to count.Based on this, Network Management Equipment is received from base
After the measurement report of the carrying RSRP value of station equipment, it can know RSRP value corresponding to every kind of power headroom, can then obtain
Know RSRP value when power headroom is 0.
Step C, Network Management Equipment carries out ascending sequence to the RSRP value of selection.
Specifically, Network Management Equipment is after RSRP value when to select power headroom in measurement report be 0, more than these power
RSRP value when amount is 0 carries out ascending sequence.
Step D, Network Management Equipment chooses n-th RSRP value as the corresponding RSRP value of base station equipment.
In the embodiment of the present invention, the method for determination of N is specifically including but not limited to: as (the quantity * y% of the RSRP value of selection)
When being positive integer, Network Management Equipment determines that the value of N is (the quantity * y% of the RSRP value of selection)；When (the number of the RSRP value of selection
Measure * y%) when not being positive integer, Network Management Equipment determines that the value of N is just less than first of (the quantity * y% of the RSRP value of selection)
Integer.
For example, it is assumed that 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, Network Management Equipment determines that the value of N is 3 at this time, and chooses the 3rd RSRP value (i.e. by small
The 3rd RSRP value to after big sequence) it is used as the corresponding RSRP value of base station equipment；When the power headroom selected from measurement report
When the quantity of RSRP value when being 0 is 50, then (the quantity * y% of the RSRP value of selection)=2.5, Network Management Equipment determines taking for N at this time
Value is first positive integer of the 2(i.e. less than 2.5), and choose the 2nd RSRP value (the 2nd RSRP after i.e. ascending sequence
Value) it is used as the corresponding RSRP value of base station equipment.
