| Interference macro station community ID | Disturbed Wei Zhan community ID |
| M1 | {P1} |
| M2 | {P1，P2} |
| M3 | {P2} |
Preferably, in S102, according to micro-station ABS resource utilization that each micro-station in disturbed micro-station set of each interference macro station reports, determine the ABS resource utilization of each interference macro station, comprise with under type:
To each interference macro station, perform following steps:
According to each micro-station cell ID in disturbed micro-station set of this interference macro station, from micro-station ABS resource utilization that each micro-station reports, determine micro-station ABS resource utilization at the micro-station by the interference of this interference macro station;
By micro-station ABS resource utilization weighted average at the micro-station by the interference of this interference macro station, obtain the ABS resource utilization of this interference macro station.
Particularly, as above in example, micro-station interference management unit gets the ABS resource utilization at disturbed micro-station that disturbed micro-station P1 and P2 reports, 80% and 90% respectively, micro-method of standing ABS resource utilization that then micro-station interference management cell processing P1 and P2 reports is: according to disturbed micro-station set of interference macro station each in table 2, search respectively and M1, M2, M3 is disturbed micro-station one to one, from disturbed micro-station of each interference macro station, disturbed micro-station of M1 is P1, the ABS resource utilization then disturbing macro station M1 is 80%, disturbed micro-station of M2 is P1 and P2, the ABS resource utilization then disturbing macro station M2 is (80%+90%)/2=85%, disturbed micro-station of M3 is P2, the ABS resource utilization then disturbing macro station M3 is 90%.
In step s 103, disturbed micro-station set of each interference macro station and/or the ABS resource utilization of interference macro station are sent to and disturb macro station accordingly; As in above-mentioned example, micro-station interference management unit have sent three message respectively to M1, M2 and M3, if do not adopt micro-station interference management cell processing method, then disturbed micro-station P1 and P2 can be caused to send 4 message to interference micro-station M1, M2 and M3 respectively; At step 104, receive the ABS pattern of each interference macro station, and gather according to disturbed micro-station of each interference macro station, the ABS pattern of interference macro station is sent to each micro-station in corresponding disturbed micro-station set; As in above-mentioned example, micro-station interference management unit sends two message respectively to disturbed micro-station P1 and P2, if do not adopt micro-station interference management cell processing method, then can cause disturbing micro-station M1, M2 and M3 to send 4 message respectively to disturbed micro-station P1 and P2, the visible centralized management by introducing micro-station interference management unit, reduce frequent information interaction between disturbed micro-station and interference macro station, reduce the load that interference macro station processes in real time further.
