User's industry cannot be met in the case where number of users is larger in order to solve LTE network in the prior art
The problem of business demand, the invention provides the resource regulating method in a kind of LTE network, below in conjunction with accompanying drawing
And embodiment, the present invention will be described in further detail.It should be appreciated that specific reality described herein
Apply example to be only used to explain the present invention, do not limit the present invention.
Embodiment 1
The resource regulating method in a kind of LTE network is present embodiments provided, Fig. 1 is the flow chart of the method,
As shown in figure 1, the method can specifically include following treatment：
Step 101：Demand of the occupancy and UE of RB to RB in monitoring LTE cells；
Wherein, in monitoring Long Term Evolution LTE cells in the occupancy and cell of RB UE to the need of RB
Asking can specifically include：The occupancy situation of RB, total RB quantity in monitoring preset time period, in net UE
Flow, net UE traffic demand and UE GBR.
Step 102：Judge whether the scheduling of RB in cell balances according to the data that monitoring is obtained；
Before judging whether the scheduling of RB in cell balances according to the data that obtain of monitoring, according to it is default when
Between in section RB occupancy situation, total RB quantity, calculate the utilization rate of RB in preset time period；According to
In the flow and the traffic demand in net UE of net UE in preset time period, QoS satisfactions, meter are calculated
Calculate the GBR sums of UE in cell.
Wherein, according to the data that obtain of monitoring judge the scheduling of RB in cell whether balance including：It is determined that pre-
If whether more than the first preset value, in preset time period, not up to QoS expires the utilization rate of RB in the time period
Whether the UE of meaning degree accounts for the ratio of all UE quantity in cell more than in the second preset value, preset time period
The traffic demand of hot zones whether the ensures bit rate GBR more than the UE in the 3rd preset value and cell
Whether sum is more than the 4th preset value；When the judged result of at least one of the above situation is to be, cell is determined
The scheduling of interior RB is uneven.
Step 103：If balance, frequency division scheduling is maintained；
Step 104：If uneven, dispatching space division is carried out to the UE in cell.
Embodiment 2
Resource in the LTE network that the present embodiment is provided the present invention by disclosing more ins and outs
UE dispatching methods are further elaborated.
Because when the LTE local resources utilization rate time not high, all UE are dispatched using frequency division in cell
System requirements can just be met, without carrying out dispatching space division, and when local resource utilization rate is higher, continued
The QoS demand of more UE is not being met in it may result in cell by the way of frequency division is dispatched, or portion
The problem that the UE accessed after point cannot be accepted, therefore unlatching space division is taken when the utilization of resources is higher in the cell
The strategy of scheduling, then can improve cell throughout, and UE satisfaction.
Based on above-mentioned analysis, it is necessary first to count the occupancy situation of RB, calculating in cell in preset time period
Total RB quantity in the time period, calculates the utilization rate of RB in the time period；In statistics preset time period
In the traffic conditions of network UE, and the UE traffic demand situation, calculate eating dishes without rice or wine in the time period
Bandwidth, calculates the ratio of hot zones traffic demand in the time period；Calculate all UE in preset time period
GBR sums, and be compared with interface-free resources, calculate the phenomenon for whether being likely to occur network congestion.
After statistically stating parameters, if it is decided that the occupancy of total RB resources is more than preset judgement
Thresholding, the customer flow demand of hot zones are more than the decision threshold of threshold value, the GBR sums of user and are more than
The UE numbers that preset decision threshold, QoS satisfactions are not reaching to preset decision threshold are more than preset thresholding
When, then into dispatching space division flow, to user, the QoS of the traffic demand more than preset thresholding of hot zones
The user that satisfaction is not up to preset decision threshold carries out dispatching space division.
