The collocation method of heterogeneous network ABS of the present invention as shown in Figure 1, mainly can comprise the steps:
Step 101: the interfered cell base station obtains the indication of ABS configure trigger from the interfered cell base station and/or ABS utilizes state information and/or user profile;
Concrete, ABS configuration adjustment cycle arrives or the ABS configuration is adjusted when being triggered, each interfered cell base station sends the indication of ABS configure trigger to the interfered cell base station and/or ABS utilizes state information and/or user profile, and the indication of ABS configure trigger and/or ABS that the interfered cell base station receives each interfered cell base station transmission utilize state information and/or user profile.Here, described ABS configuration adjustment cycle can adopt default configuration or can unify configuration; The triggering that described ABS configuration is adjusted can be: the interfered cell base station is according to the business load change triggers of self, perhaps by the interfered cell base station according to the business load change triggers.
Wherein, the interfered cell base station has judged whether to get access to the ABS configuration information that the interfered cell base station has been configured and wherein whether has had an effective ABS, if, then when ABS configuration adjustment cycle arrival or ABS configuration adjustment triggering, send ABS to the interfered cell base station and utilize state information and/or user profile; Otherwise, when ABS configuration adjustment cycle arrival or ABS configuration adjustment triggering, send the ABS configure trigger to the interfered cell base station and indicate and/or user profile.
Here, described ABS utilizes state information can comprise that whether expression interfered cell base station dispatched disturbed user's information and interfered cell base station in resource quantity or the ratio shared with the disturbed user of subframe scheduling corresponding to the ABS of interfered cell base station configuration in the subframe corresponding with the ABS of interfered cell base station configuration.Wherein, the expression interfered cell base station information of whether having dispatched disturbed user in the subframe corresponding with the ABS of interfered cell base station configuration be specially the interfered cell base station with subframe indication or quantity or the ratio of the disturbed CU of subframe scheduling corresponding to the ABS of interfered cell base station configuration.Perhaps, described ABS utilizes state information can comprise that the interfered cell base station is in the subframe ratio of the subframe scheduling disturbed CU corresponding with the ABS of interfered cell base station configuration, dispatching product between the shared resource ratio of disturbed user with the interfered cell base station with subframe corresponding to the ABS of interfered cell base station configuration.
Here, described user profile can comprise the total number of users amount of be interfered among the user of the interfered cell strongly disturbing number of users of cell base station and interfered cell.Perhaps, can comprise user's percent information of interfered cell, the ratio between the total number of users amount of be interfered among the user that this user's percent information is the interfered cell strongly disturbing number of users of cell base station and interfered cell.In the practical application, can judge the user strongly disturbing user of cell base station that whether is interfered according to the Reference Signal Received Power (RSRP, Reference Signal Received Power) of the base station in service sector of user terminal measurement report and/or neighbor cell base station.
Here, described interfered cell also obtains the user profile of self, and this user profile comprises the total number of users amount of interfered cell.
Step 102: the interfered cell base station utilizes state information and/or user profile according to described ABS configure trigger indication and/or ABS, determines current ABS configuration quantity;
Particularly, the interfered cell base station utilizes state information and/or user profile according to described ABS configure trigger indication and/or ABS, determines the ABS allocation ratio; Calculate again the ABS quantity of needs configuration according to determined ABS allocation ratio, and the smaller value between the described ABS configuration quantity maximum that needs the ABS quantity of configuration and set in advance is defined as current ABS configuration quantity.
