Fig. 1 is the collocation method flow chart of data service downlink power control function provided by the invention.
As shown in Figure 1, the method comprises:
In this step, can obtain the cell information of each community predeterminable area from network management platform or base station controller (BSC).Described presumptive area refers to need to carry out the data service downlink power control function region of configuration automatically, can comprise: the base station scope that one or more BSC control, or the control range of one or more network management platforms.Can from network management platform or BSC, obtain cell information in real time or periodically.
Described cell information comprises cell load information, can also comprise other information of community, such as adjacent cell list information of subdistrict frequency point information, community etc.Described cell load information can comprise voice load information, such as every line telephone traffic etc., and loads of data traffic information, such as data service TBF reusing degree etc.
Wherein, about the load of community, equal the situation of described predetermined threshold value, also can be according to making an appointment, execution step 104.
Unlatching in this step, refer to if there is no turn-on data business downlink power control function in this community, in Ze Gai community, turn-on data business downlink power control function, if opened data service downlink power control function in this community, is held open state.
Closing in this step, refer to if there is no turn-on data business downlink power control function in this community, turn-on data business downlink power control function in Ze Bugai community, keep closed condition, if opened data service downlink power control function in this community, close the data service downlink power control function in this community.
In order further to reduce presence of intercell interference, improve network communication quality, the application also proposes, when the load of community is more than or equal to described predetermined threshold value, in Gai community turn-on data business downlink power control function, can also the adjacent cell of Gai community in also turn-on data business downlink power control function.When the data service downlink power control function that judges whether to close in certain community, except judging whether the load condition of this community meets threshold value requirement, whether the load condition that can also judge the adjacent cell of this community also meets threshold value requirement, when the load of Ji Danggai community and adjacent cell thereof is all less than described predetermined threshold value, Cai Gai closes community data service downlink power control function.
Wherein, the adjacent cell of community can comprise: the adjacent cell list Zhong community of this community, can also comprise identical and nearest apart from this community community of frequency of Yu Gai community.Wherein, in the community beyond the adjacent cell list of Cong Gai community, find identical and nearest apart from this community community of frequency of Yu Gai community.
In Fig. 1, the information on load of community can comprise speech business information on load and loads of data traffic information.
At present, Zone information on load is general adopts the mode that loads of data traffic is converted to equivalent speech traffic load to represent, loads of data traffic and speech business load all adopt every line telephone traffic to weigh.If adopt the method for this expression Zone information on load, method shown in Fig. 1 can only arrange a kind of threshold value, loads of data traffic is converted to equivalent speech traffic load, whether the load sum that judges this equivalence speech business load and speech business itself is more than or equal to predetermined threshold value, if, carry out the action of described unlatching, otherwise, the action of closing described in execution.
Yet, applicant finds, if loads of data traffic is converted to equivalent speech traffic load, and whether turn-on data business descending power is adjusted function in Fig. 1, to adopt a kind of threshold decision, the accuracy of the cell load state obtaining is poor, and then it is lower to determine the accuracy of the suitable cell that needs turn-on data business downlink power control function.
Therefore, in order to improve the accuracy of turn-on data business downlink power control function in suitable community, applicant proposes, can adopt respectively different indexs to represent speech business information on load and loads of data traffic information, for example, adopt every line telephone traffic to represent speech business information on load, adopt Temporary Block Flow (TBF) reusing degree to represent loads of data traffic information, loads of data traffic information can also adopt (the PDCH number summation that every user is shared)/(maximum TBF reusing degree * available PDCH number of time slots) * 100% to represent.Correspondingly, in method shown in Fig. 1, speech business load threshold value and loads of data traffic threshold value are set respectively, when the speech business load of community is more than or equal to default speech business load threshold value or loads of data traffic and is more than or equal to default loads of data traffic threshold value, carry out the action of described unlatching, when the loads of data traffic that is less than default speech business load threshold value, Qie Gai community and adjacent cell thereof when the speech business load of community and adjacent cell thereof is less than default loads of data traffic threshold value, the action of closing described in execution.
In Fig. 1, can periodically perform step 103, periodically judge whether the load of community is greater than predetermined threshold value, the concrete value in judgement cycle can arrange according to the needs of network, but is limited to the update time of network condition data.For example, generally, network management platform can upgrade primary network information for 15 minutes the soonest, and the judgement cycle of therefore whether opening for data service downlink power control function is 15 minutes the soonest.But, because the power of this function effect network is controlled, therefore without frequently opening.Therefore, generally, each hour once adjudicates.
