Exemplary, the second base station calculates the 3rd RB utilization rates, if hypothesis K=2, i.e. measurement period are 2 TTI, I=3, I.e. the number of the first user equipment is 3.Wherein, RB_i,kFor institute in k-th of TTI of i-th of first user equipmenies in K TTI The RB sums used, RB_totIt is available for the 2nd FDD cells of all accesses to enter in each TTI in K TTI for the 2nd FDD cells The RB sums that the user equipment of industry business transmission uses, RB_tot=18.

Assuming that RB_1,1=3, i.e. RB sum of the 1st the first user equipment used in the 1st TTI in 2 TTI be 3；RB_1,2RB sum of=4 i.e. the 1st the first user equipment used in the 2nd TTI in 2 TTI is 4；RB_2,1=5 are RB sum of 2nd the first user equipment used in the 1st TTI in 2 TTI is 5；RB_2,2=3 i.e. the 2nd first use RB sum of the family equipment used in the 2nd TTI in 2 TTI is 3；RB_3,1=4 i.e. the 3rd the first user equipmenies are at 2 RB sums used in the 1st TTI in TTI are 4；RB_3,2=4 be the 2nd of the 3rd the first user equipment in 2 TTI RB sums used in individual TTI are 4.Thus, the second base station can be calculated the 3rd RB utilization rates according to formula two and be：

3rd RB utilization rates can be calculated by examples detailed above：α=63.8%.

The base stations of S201b ' second judge whether the 3rd RB utilization rates are more than the 3rd utilization rate threshold value.

Wherein, the 3rd utilization rate threshold value can be fixed value preset in the second base station, and the fixed value is by equipment vendors' root Obtained according to a large amount of emulation experiments；3rd utilization rate threshold value can also be that the second base station is used according in the 2nd FDD cells all first Quality of service determination of the family equipment to the first user equipment in RB service condition and the 2nd FDD cells, such as the second base station Can be with the RB utilization rates of the first user equipment of the FDD cells of real-time statistics the 2nd, and first in the 2nd FDD cells is monitored in real time The quality of service of user equipment；3rd utilization rate threshold value is determined according to statistics and monitoring result, the 3rd utilization rate threshold value can be with When being had an impact for the first user apparatus service quality in the 2nd FDD cells, the RB profits of the first user equipment of the 2nd FDD cells With the higher limit of rate.The embodiment of the present invention is not specifically limited to this.

If specifically, the 3rd RB utilization rates are more than the 3rd utilization rate threshold value, S201c ' is continued executing with：

S201c ', the second base station are dry to first base station transmission first by the X2 interface between first base station and the second base station Disturb instruction.

It should be noted that the first interference instruction may be referred in S201c to the associated description of the first interference instruction, this reality Example is applied to repeat no more here.

Wherein, first base station it is determined that the first FDD cells user equipment to the first user equipment produce interference after, then may be used So that the business of at least one second user equipment is transmitted by the first FDD cell schedulings to the first TDD cell, to reduce the first base The user equipment for the first FDD cells stood is to co-channel interference caused by the first user equipment.Wherein, first base station will be at least one The business of second user equipment is transmitted can specifically include S202- by the method for the first FDD cell schedulings to the first TDD cell S203：

S202, first base station are according to the attribute of second user equipment, it is determined that during the business transmission of scheduling second user equipment, The load balancing priority of second user equipment.

It should be noted that user equipment when accessing network, can report the access capability of the user equipment to base station Information, the access capability information can serve to indicate that the user equipment only possesses FDD cells access capability, user equipment only possesses TDD cell access capability or user equipment are provided simultaneously with FDD cells access capability and TDD cell access capability.First base station Can be according to the access capability information of user equipment to report, by the overlapping covered of the first FDD cells and the first TDD cell It is interior, FDD cells access capability and TDD cell access capability are provided simultaneously with, and access the use that the first FDD cells carry out business transmission Family equipment is defined as second user equipment.

Wherein, the attribute of second user equipment is used to indicate that second user equipment is carrier aggregation (Carrier Aggregation, CA) user equipment, or, the attribute of second user equipment is used to indicate that second user equipment is non-CA user Equipment；The load balancing priority of CA user equipmenies is higher than the load balancing priority of non-CA user equipmenies.

Wherein, CA user equipmenies are the second user equipment for possessing FDD cells access capability and TDD cell access capability In, the user equipment of FDD cells and TDD cell can be accessed simultaneously in synchronization, i.e. the business transmission of CA user equipmenies can To be carried out in FDD cells and TDD cell simultaneously, rather than CA user equipmenies is possess FDD cells access capability and TDD cell connects In the second user equipment for entering ability, synchronization may only access the user equipment of FDD cells or TDD cell, i.e., non-CA User equipment synchronization may only transmit in the enterprising industry business of a cell in FDD cells or TDD cell, and non-CA The interruption of Millisecond occurs when being switched to TDD cell by FDD cells for user equipment, influences quality of service, therefore the first base Priority scheduling of standing CA user equipmenies, the modes of such priority scheduling CA user equipmenies sufficiently consider the experience sense of user by.
