Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention, in optional a kind of application scenarios, as shown in Figure 1, when terminal 20 sends upward signal to the base station 100 under community, place (Serving cell), base station 101-106 under base station 100 and neighbor cell under Serving cell can receive the upward signal of this terminal 20, now, and the upward signal that terminal 20 sends, will the other-end in Serving cell be produced and be disturbed, also can the terminal in neighbor cell be produced and be disturbed.
Be understandable that, be subject to the neighbor cell that this terminal 20 disturbs and can belong to same wireless network control apparatus, for example wireless network control apparatus (Radio Network Controller, RNC), also may belong to different wireless network control apparatus.
Neighbor cell in the embodiment of the present invention can be to receive the community except this Serving cell of the upward signal of terminal 20.
When base station 100 adopts method that the embodiment of the present invention provides to carry out scheduling of resource to terminal 20, can efficient balance terminal 20Dui community in the interference of other-end.
Below the method that the embodiment of the present invention is provided is described in detail.
As shown in Figure 2, the embodiment of the present invention provides a kind of resource regulating method, and the method can be carried out by base station, comprising:
201, base station obtains the dispatching priority of terminal, and described dispatching priority is determined the interference of community according to described terminal by base station;
Wherein, to the dispatching priority of the little terminal of area interference higher than the dispatching priority to the large terminal of area interference, be understandable that, the size of interference is herein relative concept, higher with respect to the dispatching priority of the terminal of disturbing larger terminal as long as disturbing the dispatching priority of less terminal.
For example, described base station can be the base station 100 in Fig. 1, described base station 100 can be dispatched terminal 20 in current dispatching cycle, it should be noted that, need the terminal of scheduling to have a scheduling base station 100 more than one, and in Fig. 1, be mainly used in illustrating the dispatching priority of base station 100 how to confirm terminals 20.
Wherein, described dispatching priority is determined according to the interference of terminal 20Dui community by base station 100;
The community here can be the Serving cell of terminal 20; Or described community comprises Serving cell and the neighbor cell of terminal 20, described neighbor cell is the community except described Serving cell that receives the upward signal of terminal 20.
In the time that described community comprises the Serving cell of terminal 20 and neighbor cell, can comprise multiple situation: for example, described community comprises in all communities that belong to base station 100 has with described terminal 20 all communities that are connected;
Or described community comprises all communities that belong to base station 100;
Or described community comprises in all communities that belong to all communities of base station 100 and belong to adjacent base station having with described terminal 20 community being connected;
Or described community comprises all communities that belong to base station 100 and all communities that belong to adjacent base station.
Wherein, adjacent base station is the base station under neighbor cell, and this adjacent base station is different from base station 100.
Wherein, and the mode of according to terminal, the interference of community being determined the dispatching priority of terminal can have multiple, as long as make can be balanced after dispatching priority is determined the interference that produces of terminal, the relation of the dispatching priority of the terminal of for example determining and the interference of described terminal to community can be: in the time that terminal is larger to the interference of community, the dispatching priority of described terminal can be lower, otherwise, when terminal to the interference of community more hour, the dispatching priority of described terminal can be higher.The embodiment of the present invention is follow-up will be described in detail the mode of the dispatching priority of the possible definite terminal of some of them.
202, described base station is carried out resource distribution according to the dispatching priority of described terminal to described terminal.
Wherein, the implementation of this step can be carried out resource distribution to the low terminal of dispatching priority for base station has precedence over the high terminal of dispatching priority, be understandable that, the height of dispatching priority is herein relative concept, as long as make the terminal that dispatching priority is higher can priority allocation resource, and can have various ways to the higher terminal priority allocation resource of dispatching priority, be for example the transmission rate that promotes the terminal that dispatching priority is higher, or reduce the transmission rate of the terminal that dispatching priority is lower.
For example, in the time there are available resources in the Serving cell of described terminal resource, base station can be according to dispatching priority order from high to low to all or part of available resources of terminal distribution, by such mode, can make the transmission rate of the terminal that dispatching priority is high get a promotion, optionally, also can be outside the transmission rate that makes the terminal that dispatching priority is high gets a promotion, reduce the sort transmission rate of a posterior N terminal of dispatching priority, N be herein natural number according to different actual conditions, its numerical value may be different; Or, in the time that the load of the Serving cell of described terminal is greater than default thresholding, described base station according to dispatching priority according to order from low to high, reduce the transmission rate of terminal, make the load of described Serving cell at least be reduced to described default thresholding, that is to say the transmission rate that reduces the terminal that dispatching priority is lower, alternatively, be no more than default thresholding in the case of meeting the load of Serving cell, also can reduce outside the transmission rate of the terminal that dispatching priority is low, consider the transmission rate of the high part terminal of dispatching priority to promote.Understandable, default thresholding herein can arrange according to actual needs, and the embodiment of the present invention does not limit this.
Concrete, how base station carries out resource is divided the transmission rate that is equipped with lifting terminal or the transmission rate that reduces terminal, can adopt multiple implementation, in this no limit.
Alternatively, in dispatching cycle, resource distribution can the higher terminal of priority scheduling priority be carried out in base station, and the terminal that more late dispatching priority is lower is carried out resource distribution.
For the higher terminal A of dispatching priority, base station can be for this terminal A allocation of transmission resources be to promote the transmission rate of this terminal A;
For the lower terminal B of dispatching priority, base station can be for this terminal B allocation of transmission resources be to reduce the transmission rate of this terminal B.
In the embodiment of the present invention, base station is before dispatch terminal, can determine the dispatching priority of terminal, because dispatching priority is that base station is determined the interference of community according to described terminal, thereby, base station adopts the dispatching priority of this terminal to carry out after resource distribution terminal, the interference can efficient balance terminal producing.
For example, base station is before dispatch terminal, if the interference that terminal produces is less, determines that the dispatching priority of this terminal can be higher, thereby base station is after this terminal of scheduling, and the transmission rate of this terminal may get a promotion, and the interference of corresponding generation can increase;
And base station is before dispatch terminal, if the interference that terminal has produced is larger, determine that the dispatching priority of this terminal can be lower, thereby base station is after this terminal of scheduling, the transmission rate of this terminal may be reduced, and the interference of corresponding generation can reduce.
Thereby, after base station is to terminal scheduling, the interference can efficient balance terminal producing.
Be understandable that, in the cycle of terminal being dispatched in base station, may there is more than one terminal, for each terminal, the mode of determining the dispatching priority of this terminal is similarly, can be within a dispatching cycle so, determine the dispatching priority of each terminal by the mode of traversal, as shown in Figure 2 a, the embodiment of the present invention provides a kind of implementation of above-mentioned resource regulating method, specifically comprises:
2011, base station, in current dispatching cycle, travels through each terminal, and for the current terminal being traversed, base station obtains the interference of this terminal to community;
2021, described base station obtains the dispatching priority of described terminal to the interference of community according to described terminal;
2031, described base station judges whether to exist the terminal not traversing;
If the terminal that existence does not traverse is judged in described base station, in the terminal never traversing, determine next terminal, and jump to step 2011 and obtain the interference of described next terminal to community;
If 2041, described base station is judged and do not had the terminal not traversing, according to dispatching priority, terminal is carried out to resource distribution.
Be understandable that, in above-described embodiment, to be that the dispatching priority of determining terminal in current dispatching cycle describes as example take base station, and in fact, be not limited to this opportunity of determining the dispatching priority of terminal, for example, dispatching priority that can uncertain terminal in current dispatching cycle, but obtain the dispatching priority of terminal definite in dispatching cycle before, divide timing when carrying out resource to terminal so, can be directly from the record of the dispatching priority of definite terminal during dispatching cycle before of preservation, obtain the dispatching priority of terminal.
In the embodiment of the present invention,, can adopt following several implementation to obtain the interference of terminal to community, following implementation all describes as example the interference of community to obtain a terminal:
As shown in Fig. 3 and Fig. 3 a, the embodiment of the present invention provides in a kind of resource regulating method and obtains a kind of implementation method of terminal to area interference, and community described in the method comprises Serving cell and neighbor cell.
Obtaining terminal 20 specifically comprises a kind of implementation method of area interference:
3011, the interference that described terminal 20 produces Serving cell is determined in base station 100;
3012, the interference that the described terminal 20 that the base station under 100 reception of neighboring cell, base station sends produces neighbor cell.
For example, take the interference of 100 terminal 20Dui communities, base station in Fig. 3 as example, the interference of terminal 20 to Serving cell can be determined in base station 100 under described terminal 20 Serving cells, base station 101-106 under neighbor cell determines the interference of described terminal 20 to adjacent base station, and send to base station 100(as shown in the solid line that the base station 101-106 under neighbor cell in Fig. 3 points to base station 100), thereby, base station 100 can obtain the interference of terminal 20 to Serving cell and neighbor cell, afterwards, base station obtains the dispatching priority of terminal 20 to the interference of Serving cell and neighbor cell according to terminal 20, and according to the dispatching priority of terminal 20, terminal 20 is carried out to resource distribution (as shown in the dotted line that terminal 20 is pointed in base station in Fig. 3 100).
It should be noted that, the base station under neighbor cell can be by the preset interface between base station, and terminal 20 is sent to the base station 100 described in Serving cell to the interference of neighbor cell;
Or the base station described in neighbor cell can first send to the wireless network control apparatus under neighbor cell to the interference of neighbor cell by terminal 20, is transmitted to the base station 100 under Serving cell by this wireless network control apparatus.
It should be noted that, the terminal 20 that Fig. 3 describes is above to be obtained by the base station under neighbor cell to the interference of neighbor cell, send to the base station 100 of Serving cell, certainly, alternately, base station under above-mentioned neighbor cell can will disturb relevant parameter to send to the base station 100 under Serving cell, then obtains the interference of terminal 20 to described neighbor cell by the base station 100 under Serving cell according to described interference relevant parameter.
Described interference relevant parameter can be for example the parameter that in following mode A-E, the separate equations relates to.
Be understandable that, it is identical to the conflicting mode of Serving cell that the mode that the base station under described neighbor cell obtains the interference of terminal 20 to described neighbor cell and base station 100 obtain terminal 20.
Obtain terminal below describes as example the interference of Serving cell take base station.
Further, base station obtains the mode of the interference of described terminal to Serving cell generation, can adopt following several realization:

For example, described base station 100 receives the interference of described terminal 20 to Serving cell that service radio network control appliance sends, and described terminal 20 is obtained and drawn and send to base station 100 by described service radio network control appliance the interference of Serving cell.
And for example, described base station 100 receives the interference of described terminal 20 to neighbor cell that service radio network control appliance sends, described terminal 20 is obtained and is drawn and send to service radio network control appliance by adjacent wireless network control apparatus the interference of the neighbor cell that does not belong to the management of service radio network control appliance, and described service radio network control appliance is transmitted to base station 100.
