Along with the development of mobile Internet, the user of mobile data services gets more and more.In order to meet user's needs, the mode of different service types differentiated service is adopted for different user, realize the service quality (QualityofService, QoS) of business is controlled, charging control and thresholding control, third generation partner program (3 ^rdgenerationPartnershipProject, 3GPP) introduce policy control and charging (PolicyControlandCharging, PCC) technology.

PCC technology is according to specific policy reasonable distribution/schedule network resources, the technology realizing differentiated service and service management in packet network.Existing PCC framework mainly comprises: policy control and charging regulation function entity (PolicyandChargingRulesFunction, PCRF), policy control and charging execution function entity (PolicyandChargingEnforcementFunction, PCEF), Gateway GPRS Support Node (GatewayGPRSSupportNode, GGSN), business and OSS (Business & OperationSupportSystem, BOSS) etc.Wherein, PCEF can be arranged in gateway GGSN, also can independently dispose.

PCRF carries out decision-making according to the user signing contract information obtained from BOSS, business information and operator's pre-defined rule etc., generating network management and control strategy, and by the network management and control policy distribution that generates to PCEF, carry out Internet resources regulation and control according to the network management and control strategy received for the different service types of different user by PCEF.

According to such scheme, according to the static settings such as user signing contract information, business information, there is following problem in network management and control strategy in PCRF use procedure:

The first, when a large amount of low-level business takies wireless bandwidth, frequently cause network blockage, PCEF uses the network management and control strategy of static settings to decline causing the service quality of business;

The second, when wireless bandwidth is idle, PCEF uses the network management and control strategy of static settings to cause the utilance of wireless network resource lower.

In prior art, described network management and control strategy can be sent to the base station controller of corresponding base station by PCEF further, carries out direct regulation and control by base station controller to Radio Resource.

Step 202:PCC feedback unit, according to described Radio Resource load information, determines the wireless resource scheduling information adjusting described network management and control strategy.

In step 202., Radio Resource load information can be determined in the lte networks in the following manner:

N continuous in time domain _symbin individual single-carrier frequency division multiple access (Single-carrierFrequencyDivisionMultipleAccess, SC-FDMA) symbol and frequency domain continuously individual subcarrier is defined as a Physical Resource Block PRB.

Wherein, N _symbwith relation as shown in table 1.

Table 1

Therefore, a Physical Resource Block in up link by individual Resource Unit composition, 1 time slot of corresponding time domain and the 180kHz of frequency domain.

Wherein, described setting thresholding can be determined according to the utilization rate of PRB resource, also can be determine by other means, not limit here.

Suppose that described setting thresholding is determined according to the utilization rate of PRB resource, the described Radio Resource load information that now PCC feedback unit receives also is represented by the utilization rate of PRB resource.

When described Radio Resource load information is greater than setting thresholding, the Radio Resource heavier loads of current area is described, determines that the wireless resource scheduling information adjusting network management and control strategy is reduce the Radio Resource of described network management and control strategy.

Particularly, the mode reducing the Radio Resource of described network management and control strategy includes but not limited to one or more under type:

The first: according to the grade of type of service, discharge the PRB resource shared by non-bearer service user.

The second: release type of service grade is less than the PRB resource of the CU of setting grade threshold.

Wherein, the grade of type of service can be represented by the grade of load, and such as: the grade of load 0 represents non-loaded, the grade of load 1 represents slight load, and the grade of load 2 represents normal load, and the grade of load 3 represents important load, and the grade of load 4 represents severe load.

Wherein, described setting thresholding can be determined according to the utilization rate of PRB resource, also can be determine by other means, not limit here.

Suppose that described setting thresholding is determined according to the utilization rate of PRB resource, the described Radio Resource load information that now PCC feedback unit receives also is represented by the utilization rate of PRB resource.

When described Radio Resource load information is greater than setting thresholding, illustrate that the Radio Resource load of current area is comparatively light, determine that the wireless resource scheduling information adjusting network management and control strategy is the Radio Resource increasing described network management and control strategy.

Wherein, the mode increasing the Radio Resource of described network management and control strategy includes but not limited to:

According to the grade of type of service, increase the PRB resource that type of service grade is greater than the CU of setting grade threshold.

Like this, being greater than the PRB resource of the CU of setting grade threshold by increasing type of service grade, making to be in idle wireless network resource and being fully used, and then improve the utilance of wireless network resource.

Particularly, the Radio Resource of the described network management and control strategy after reducing/increasing is determined in the following manner:

$N_{\mathrm{PRB}}^{\mathrm{new}}=\frac{N_{\mathrm{PRB}}^{\mathrm{used}}}{N_{\mathrm{PRB}}^{\max }}\×N_{\mathrm{PRB}}^{\mathrm{old}\_\mathrm{used}}+\mathrm{\β}\×(N_{\mathrm{PRB}}^{\max }-N_{\mathrm{PRB}}^{\mathrm{old}\_\mathrm{used}});$

Wherein, for adjusting the Radio Resource of rear network management and control strategy, for adjusting the Radio Resource of front network management and control strategy, represent the Radio Resource that network management and control strategy configures at most, represent the utilization rate of current radio resource, β is predefined ratio value.

Described wireless resource scheduling information is sent to policy control and billing function entity PCRF by step 203:PCC feedback unit, and described PCRF is adjusted described network management and control strategy according to described wireless resource scheduling information.

In step 203, PCC feedback unit determines the PRB resource information needing adjustment, the described PRB resource information of adjustment that needs is sent to PCRF, and PCRF determines to need increase to call PRB resource according to the described PRB resource information of adjustment that needs, or PRB resource is called in minimizing.

Particularly, PCRF, according to the corresponding relation of system bandwidth in table 2 and PRB resource, determines the number needing the PRB resource increasing/reduce for any one community.
