Embodiment one, embodiments of the invention provide a kind of network load balancing method, include as shown in Figure 1：
S101, when it is determined that the RRC utilization rates in communication cell are more than or equal to predetermined threshold value, according to the industry of terminal device Business species, generation release SCC configuration information.
It should be noted that firstly the need of acquisition network parameter in the application of reality, and counted according to network parameter Calculate；Wherein, network parameter includes：The maximum that the current RRC connection number Num_RRC_now in communication cell and the communication cell are supported RRC connection number Num_RRC_max simultaneously calculate the RRC utilization rates P in communication cell by Num_RRC_now and Num_RRC_max； Then differentiate whether P is more than or equal to predetermined threshold value Th, as P >=Th, illustrate that present communications local resource load is higher, if Support that the terminal of carrier aggregation is more in network, the actual physical terminal quantity that can access of whole net drops significantly under limit scene It is low, influence new user's access；Wherein, here the actual physical terminal quantity that can access of the whole net under limit scene substantially reduces Refer to, due to supporting the terminal device of carrier aggregation to be transmitted using multiple CC simultaneously；Exemplary, terminal device branch 1 PCC is held, 3 SCC carry out data transmission, and terminal device may only need 1 PCC and 2 simultaneously in the application of reality SCC carries out data transmission ensuring that the service request of present terminal equipment, then an extra SCC is in itself not It is utilized；Based on the presence of such a phenomenon, the RB resource-constraineds of each carrier wave in communication cell, and when multiple equipment carries out data During transmission, the RB resources of possible each carrier wave are occupied, but these occupied RB resources do not carry out the transmission of data, New terminal device can not be assigned to enough RB resources, so as to cause accessible physical terminal quantity significantly in access Reduce.
When it is determined that the RRC utilization rates in communication cell are less than predetermined threshold value, without any operation, it is small to continue collection communication RRC utilization rates in area, and be monitored.
S102 simultaneously sends the control instruction for carrying configuration information to terminal device；Wherein, configuration information is included in default SCC is stopped using to carry out data transmission in time.
Network load balancing method provided in an embodiment of the present invention, by the analysis to RRC utilization rates in communication cell, from And the number of the SCC resources of current communication cell differentiated；When the RRC utilization rates in communication cell are more than or equal to predetermined threshold value When represent that current SCC resource loads are larger, if now support CA terminal device it is more, cause on multiple SCC simultaneously Same terminal device occurs, with being on the increase for terminal device access request, because each SCC is within the same period The terminal device of carrying is limited, and the terminal device that the SCC can be carried when reaching to a certain degree reaches the limit values；Therefore need According to the class of business of terminal device, generation release SCC configuration information and by the control instruction for carrying configuration information send to Terminal device is to cause terminal device in preset time without using the SCC, so as to discharge what is taken originally by terminal device SCC, so as to which the SCC can continue to access new terminal device or new service request, ensure the experience of user；Solve existing Because terminal device takes multiple CC simultaneously in some carrier aggregation systems, cause some CC when in saturation state, new Equipment or new service request do not have the resource of the RRC connections that can be established and distribution on the CC, cause new equipment can not The problem of access or new service request can not timely respond to the experience difference of user.
Embodiment two, embodiments of the invention provide a kind of network load balancing method, have as shown in Figure 2, Figure 3 and Figure 4 The implementation of body is as follows：
It should be noted that because terminal device is when carrying out Non_GBR business and GBR traffic, corresponding handling process It is different；Therefore, the concrete methods of realizing when class of business that terminal device is provided in scene one is Non_GBR business, feelings The concrete methods of realizing when class of business that terminal device is provided in scape two is GBR traffic.
Scene one, embodiments of the invention provide a kind of network load balancing method, include as shown in Figure 2 and Figure 4：
S1010, when it is determined that the RRC utilization rates in communication cell are more than or equal to predetermined threshold value, obtain SCC on RB money Source utilization rate is more than or equal to the terminal device of default utilization rate.
It should be noted that in the application of reality, step S1010 can filter out a kind of terminal device for meeting condition, The number of terminal device now be probably one or two or two and more than；Exemplary, it is (i.e. same in carrier wave K SCC on) in the △ t periods, it is ranked up, can be expressed as according to the average of the RB resources of each terminal device distribution：
Wherein, D tables Show that resource D, RB_CA_i_K that each CA UE are distributed on the carrier wave represent i-th of support CA terminal device on carrier wave K The average of the RB resources of distribution.
S1020, when the class of business of terminal device be more than or equal to for Non_GBR business and RB resource utilizations it is default During utilization rate, generation release SCC configuration information simultaneously sends the control instruction for carrying configuration information to terminal device.
S1030, acquisition discharge the RRC utilization rates in communication cell after the SCC of terminal device.
S1040, when RRC utilization rates are more than or equal to predetermined threshold value, obtain network in terminal device support SCC number Measure N.
It should be noted that step S1030 discharges a terminal device every time in the application of reality, i.e., only release step Meet in the terminal device of condition one obtained in rapid S1010；After step S1030, if in step S1040 RRC utilization rates are still greater than or equal to predetermined threshold value, it is also necessary to meet condition to what is obtained in step S1010 and do not discharge SCC terminal device sends control instruction and (obtains the RB resource utilizations on SCC and be more than or equal to not released for default utilization rate Put SCC terminal device), if during SCC is discharged, if RRC utilization rates are still less than predetermined threshold value in step S1040 When, then the control instruction for stopping sending carrying configuration information is sent to terminal device；Or meet the end of condition in step S1010 When the SCC of end equipment is released, RRC utilization rates are still greater than or equal to predetermined threshold value in step S1040, and now explanation also needs to Discharge other terminal devices；Terminal device is when carrying out data transmission, an only PCC and multiple SCC；Wherein, here It is multiple refer to one or two or two and more than；Therefore, the terminal device requirement minimum when carrying out data transmission be One PCC and SCC, as 1 SCC that terminal device is only supported, it is impossible to discharge the SCC of the terminal device.
S1050, when N be more than or equal to 2 when, obtain terminal device support each SCC RRC utilization rates.
S1060, when RRC utilization rates are more than or equal to predetermined threshold value, obtaining the RB resources of each terminal device on SCC makes With rate.
S1070, when RB resource utilizations are less than default utilization rate, generation release SCC configuration information simultaneously matches somebody with somebody carrying The control instruction of confidence breath is sent to terminal device.
It should be noted that when access network equipment is performing S1010, S1020 and S1030 in the application of reality, need It is repeated several times；Exemplary, illustrated by taking 5 terminal devices on the SCC on same wave band as an example, its The RB resource utilizations of middle terminal device 1, terminal device 2 and terminal device 3 on SCC are more than or equal to default utilization rate, And the RB resource utilizations that the RB resource utilizations of terminal device 1 are more than terminal device 2 make more than the RB resources of terminal device 3 With rate, the RB resource utilizations of terminal device 4 and terminal device 5 on SCC are less than default utilization rate and terminal device 3 The RB resource utilizations that RB resource utilizations are more than terminal device 4 are more than the RB resource utilizations of terminal device 5 (alternatively It is：5 equipment are accessed simultaneously on SCC, the wherein RB resource utilizations of terminal device 1 are more than the RB resources of terminal device 2 Utilization rate is more than RB of the RB resource utilizations more than terminal device 5 of terminal device 4 more than the RB resource utilizations of terminal device 3 Resource utilization；Therefore, can be numbered according to RB resource utilization of the terminal device on the SCC, it is forward by numbering The SCC of terminal device is preferentially discharged).
In order to reduce the situation of SCC resource occupation, access network equipment is set by step S1010 and S1020 in release terminal , it is necessary to confirm after dischargeing the SCC that terminal device takes, the RRC utilization rates of the communication cell after the standby SCC taken；Work as release After the SCC for falling section terminating equipment occupancy, when the RRC utilization rates of communication cell are still above or equal to predetermined threshold value, obtain eventually The quantity N for the SCC that end equipment is supported；Confirm whether the RRC utilization rates on each SCC are more than or equal to predetermined threshold value；When RB is provided When source utilization rate is more than or equal to default utilization rate, the RB resource utilizations of each terminal device on SCC are obtained, then should The minimum terminal device of the upper RB resource utilizations of SCC preferentially discharges, so as to ensure that the normal of other-end equipment on the SCC Operation, the SCC of release can be used for other new equipment or the access of other business, so as to improve Consumer's Experience；And due to The terminal device of Non_GBR business is carried out, its transmission rate need not be ensured when carrying out data transmission, therefore release meets first RB resource of the terminal device of the progress Non_GBR business of condition on SCC, so as to ensure other new equipment or other industry The access of business, so as to improve Consumer's Experience；Wherein, RB resource utilization of the terminal device on SCC exists equal to the terminal device The RB resource quantities divided by total RB resource quantities of the SCC taken on SCC.
After terminal device 1 discharges SCC according to the control instruction for carrying configuration information, the RRC utilization rates of communication cell During less than predetermined threshold value, terminal device 2 and terminal device 3 (need not discharge terminal device 2 on SCC without any operation RB resources on SCC of RB resources and terminal device 3)；The RRC utilization rates of communication cell are more than or equal to predetermined threshold value When, illustrate that now communication cell resource is still higher, it is necessary to continue to discharge the SCC of terminal device 2 and/or terminal device 3 SCC。
After terminal device 2 discharges SCC according to the control instruction for carrying configuration information, the RRC utilization rates of communication cell During less than predetermined threshold value, terminal device 3 is without any operation (need not discharge RB resource of the terminal device 3 on SCC)；Communication When the RRC utilization rates of cell are more than or equal to predetermined threshold value, illustrate that now communication cell resource is still higher, it is necessary to continue to release Put the SCC of terminal device 3.
After terminal device 3 discharges SCC according to the control instruction for carrying configuration information, the RRC utilization rates of communication cell During less than predetermined threshold value, whether the RRC utilization rates that access device monitors in communication cell again are more than or equal to predetermined threshold value；It is logical When the RRC utilization rates of letter cell are more than or equal to predetermined threshold value, illustrate that now communication cell resource is still higher, it is necessary to carry out S1040, S1050 and S1060 can just alleviate the still higher situation of present communications local resource, and specific implementation is such as Under：
The SCC count amount that each terminal device is supported in the application of reality is not unique, and (terminal device here refers to support CA equipment, if terminal device does not support CA, so this method can not be realized), because access network equipment is set dischargeing terminal After standby 1, terminal device 2 and terminal device 3, the RRC utilization rates of communication cell are still above or equal to predetermined threshold value, now eventually End equipment 4 and terminal device 5 still take the SCC；Therefore, in order to further reduce the RB resource occupation problems on SCC, need The RB resources on the SCC that terminal device 4 and terminal device 5 take are discharged according to condition；Wherein, condition here refers to： When RRC utilization rates are more than or equal to predetermined threshold value, the quantity N for the SCC that terminal device is supported is obtained；When N is more than or equal to 2 When, the RRC utilization rates for each SCC that acquisition terminal device is supported；When RB resource utilizations are more than or equal to default utilization rate, Obtain the RB resource utilizations of each terminal device on SCC；When RB resource utilizations are less than default utilization rate, generation release SCC configuration information simultaneously sends the control instruction for carrying configuration information to terminal device；Exemplary, have with terminal device 4 Illustrated exemplified by having the SCC of 2 wave bands, terminal device 5 that there is the SCC of 3 wave bands, wherein terminal device 4 is in first band SCC on RB resource utilizations be less than RB resource utilization of the terminal device 5 on the SCC of first band and set in terminal The standby 5 RB resource utilizations on the SCC of first band are less than default utilization rate, preset utilization rate and are more than terminal device 4 the The RB resource utilizations of RB resource utilizations and terminal device 4 on the SCC of second band on the SCC of two wave bands are more than eventually RB resource utilization of the end equipment 5 on the SCC of second band, RB resource of the terminal device 5 on the SCC of the 3rd wave band use Rate is less than default utilization rate.
Situation one, detect that RRC utilization rates on the SCC of first band are more than or equal to default threshold when access network equipment Value, the RRC utilization rates on the SCC of second band are less than predetermined threshold value, and the RRC utilization rates on the SCC of the 3rd wave band, which are less than, to be preset During threshold value, because RB resource utilization of the terminal device 4 on the SCC of first band is less than terminal device 5 in first band RB resource utilizations on SCC；Therefore the terminal device 4 on the SCC of first band can be preferentially discharged according to condition.
Situation two, detect that the RRC utilization rates on the SCC of first band are less than predetermined threshold value when access network equipment, RRC utilization rates on the SCC of two wave bands are more than or equal to predetermined threshold value, and the RRC utilization rates on the SCC of the 3rd wave band are less than default During threshold value, because RB resource utilization of the terminal device 4 on the SCC of second band is more than terminal device 5 in second band RB resource utilizations on SCC；Therefore the terminal device 5 on the SCC of second band can be preferentially discharged according to condition.
