And change.The embodiment of the present invention is according to the different corresponding PRB ratio of candidate edge user, the corresponding PRB ratio of central user
PRB utilization rate corresponding with central user specifically enumerates following several possible situations.
Situation one:
The network equipment determines that the corresponding PRB utilization rate of the central user is greater than first threshold, and the central user pair
After the PRB ratio answered is greater than the corresponding PRB ratio of the candidate edge user, the edge band value of the first community is adjusted
For first edge frequency band values.
First edge frequency band values obtain in the following manner:
Wherein, P1 is the first edge frequency band values, and W is the maximal margin frequency band values that first community is supported, X is each institute
The sum of the PRB assessed value of candidate edge user is stated, Y is the corresponding PRB ratio of the central user.
Specifically, in the embodiment of the present invention, first threshold can the utilization rate of the user PRB centered on threshold value it is (maximum
Value), the present invention does not limit the specific value of first threshold, and those skilled in the art can according to the actual situation or experience feelings
Condition is arranged.
Situation one is illustrated below with reference to specific example.
For example, the network equipment obtains 20 users of access cell A according to the setting period from the base station of cell A, wherein
The quantity of central user is 14, and the quantity of candidate edge user is 9, and the maximal margin frequency band values that known cell A is supported
(i.e. cell A support maximal margin PRB quantity) be 30, the sum of PRB assessed value of 9 candidate edge users be 24,9
The corresponding PRB ratio of a candidate edge user is that the corresponding PRB ratio of 0.827,14 central users is 1.178,14
The corresponding PRB utilization rate of central user is 73%, and network equipment preset first threshold value is 70%.So, pair of central user
The PRB utilization rate (73%) answered is greater than first threshold (70%), and, the corresponding PRB ratio (1.178) of central user, which is greater than, waits
The corresponding PRB ratio (0.827) of edge customer is selected, the edge band value of cell A can obtain in the following manner as a result:
Wherein, P1 is the edge band value of cell A；W1 is the maximal margin frequency band values that cell A is supported, X is each in cell A
The sum of the PRB assessed value of a candidate edge user, Y are the corresponding PRB ratio of central user in cell A.
So, it according to above-mentioned condition, can be obtained by calculation:
I.e. the edge band value of cell A is 20 PRB.
In the present invention, it is contemplated that the resource requirement of central user and edge customer is dynamic change, in central user height
Under the scene of portfolio, while needing to consider the portfolio of edge customer, that is to say, that the present invention, which passes through, determines central user pair
It is corresponding greater than the candidate edge user that the PRB utilization rate answered is greater than first threshold and the corresponding PRB ratio of central user
PRB ratio shows that central user portfolio is higher, and the PRB utilization rate of central user is higher, thus using candidate edge user
The PRB assessed values of Minimum requirements adjust edge band value, meet the resource requirement of edge customer as far as possible while, protect
Demonstrate,prove the resource requirement of central user, the total service quality of lifting system.
Situation two:
The network equipment determines that the corresponding PRB utilization rate of the central user is less than or equal to first threshold, or, the network is set
It is standby if it is determined that the corresponding PRB utilization rate of the central user is greater than first threshold and the corresponding PRB ratio of the central user is small
In being equal to the corresponding PRB ratio of the candidate edge user, the edge band value of the first community is adjusted to second edge
Frequency band values.
Second edge frequency band values obtain in the following manner:
P2=min (W, Z)
Wherein, P2 is the second edge frequency band values, and W is the maximal margin frequency band values that the first community is supported, Z is each
The sum of the PRB quantity of a candidate edge user actual schedule.
Specifically, it is likely to occur the network equipment in situation two and determines that the corresponding PRB utilization rate of the central user is less than
The case where equal to first threshold；Or the network equipment determines that the corresponding PRB utilization rate of the central user is greater than first threshold, and
The corresponding PRB ratio of the central user is less than or equal to the case where candidate edge user corresponding PRB ratio.Therefore, under
Face combines specific example to be illustrated to the case where being likely to occur in situation two.
Situation A, the network equipment determine that the corresponding PRB utilization rate of the central user is less than or equal to first threshold, will be described
The edge band value of first community is adjusted to second edge frequency band values.
For example, the network equipment obtains 25 users of access cell B according to the setting period from the base station of cell B,
Wherein, the quantity of central user is 17, and the quantity of candidate edge user is 11, and the maximal margin that known cell B is supported
Frequency band values (i.e. the quantity for the maximal margin PRB that cell B is supported) are 35, the PRB of the actual schedule of 11 candidate edge users
The sum of quantity is 36, and the corresponding PRB utilization rate of 17 central users is 68%, and network equipment preset first threshold value is
70%.So, the corresponding PRB utilization rate (68%) of central user is less than first threshold (70%), as a result, the edge of cell B
What frequency band values can obtain in the following manner:
P2=min (W2, Z1)
Wherein, P2 is the second edge frequency band values, and W2 is the maximal margin frequency band values that cell B is supported, Z1 is in cell B
The sum of the PRB quantity of each candidate edge user actual schedule.
So, it according to above-mentioned condition, can be obtained by calculation:
P2=min (35,36)=35；
I.e. the edge band value of cell B is 35 PRB.
In the present invention, by determining that the corresponding PRB utilization rate of central user is less than first threshold, the center of can show that is used for
Portfolio is lower, that is, distributes to the frequency band values of central user excessively to the phenomenon that center frequency-band waste occur, for this kind of field
Scape, the PRB number of candidate edge user actual schedule of the present invention adjust edge band, can be in the resource need for meeting central user
While asking, guarantee the resource requirement of edge customer, promotes the service quality of edge customer.
Situation B, the network equipment determine that the corresponding PRB utilization rate of the central user is greater than first threshold, and the center
The corresponding PRB ratio of user is less than or equal to the corresponding PRB ratio of the candidate edge user, by the edge frequency of the first community
Band value is adjusted to second edge frequency band values.
For example, the network equipment obtains 30 users of access cell C according to the setting period from the base station of cell C,
