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 embodiment of the present invention part embodiment, rather than whole embodiment.Embodiment based in the embodiment of the present invention, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of embodiment of the present invention protection.
As shown in Figure 2, in the embodiment of the present invention, proposed a kind of load-balancing method, comprised the following steps:
Step 201, obtains the load information of a plurality of adjacent areas.
Step 202, obtains the load difference between described a plurality of adjacent area according to the load information of described a plurality of adjacent areas.When the load difference between described a plurality of adjacent areas is less than default the first load threshold, forward step 203 to; When the load difference between described a plurality of adjacent areas is greater than default the second load threshold, forward step 205 to.
In the present invention, according to the load difference between a plurality of adjacent areas, judge whether to obtain to part adjacent area the load information of the adjacent area of this part adjacent area, when the load difference between described a plurality of adjacent areas is less than default the first load threshold, according to the load difference judgement between a plurality of adjacent areas, need to obtain to part adjacent area the load information of the adjacent area of this part adjacent area, forward step 203 to, and when the load difference between described a plurality of adjacent areas is greater than default the second load threshold, the load information that does not need to obtain to part adjacent area the adjacent area of this part adjacent area according to the load difference judgement between a plurality of adjacent areas, forward step 205 to.
Concrete, described default the first load threshold and described default the second load threshold are optional load threshold according to actual needs, in actual applications, this default first load threshold and default the second load threshold can be identical, also can be different, when the two is different, default the second load threshold need to be greater than default the first load threshold.
Take the two when identical as example describes, if will preset the first load threshold (or default second load threshold), be set to 20% of cell load, a plurality of adjacent areas are respectively community 1, community 2 and community 3, the load that 3 communities can be born is identical, if according to load information learn community 1 when preload be 20%, community 2 when preload be 25%, community 2 when preload be 30%, load difference between a plurality of adjacent areas is all less than 20% of cell load, is less than default the first load threshold.
In practical application, this default first load threshold is not limited to use cell load, for example, can also use community to bear the quantity of terminal, preset the first load threshold and be set to 8 terminals, according to load information, learn that the current terminal of community 1 is 30, the current terminal of community 2 is 40, the current terminal of community 3 is 50, and the load difference between a plurality of adjacent areas is all greater than 8 terminals, is greater than default the first load threshold.Situation for other default the first load thresholds, repeats in the embodiment of the present invention no longer in detail.
Step 203, obtains the load information of the adjacent area of described a plurality of adjacent areas.
Concrete, the load information that obtains the adjacent area of described a plurality of adjacent areas comprises: it is candidate adjacent that a plurality of adjacent areas that load difference is less than default the first load threshold are set, the load information of notifying described candidate adjacent to report adjacent area separately, and receive the load information of the adjacent area separately that described candidate adjacent reports.
For example, community 1, community 2 and community 3 are set to candidate adjacent, and the load information of notifying described candidate adjacent to report adjacent area separately, community 1, community 2 and community 3 all need the load information of self adjacent area to report.
Step 204, determines the Target cell of mobility load balance MLB according to the load information of the adjacent area of described a plurality of adjacent areas.
Step 205, determines the Target cell of MLB according to the load information of described a plurality of adjacent areas.
The Target cell of determining MLB according to the load information of described a plurality of adjacent areas comprises: according to the load information of described a plurality of adjacent areas, select the Target cell that the adjacent area of loading condition optimum is described MLB.For example, according to load information, learn that the current terminal of community 1 is 30, the current terminal of community 2 is 40, and the current terminal of community 3 is 50, and community 1 is the adjacent area of loading condition optimum, can be chosen as the Target cell of MLB.
Step 206, carries out load balancing according to the Target cell of described MLB.Wherein, according to the Target cell of described MLB, carrying out load balancing comprises: the Target cell that load is diverted to described MLB.
Visible, the method that the application of the invention embodiment provides, when the load difference between a plurality of adjacent areas is little, by considering the load information of the adjacent area of a plurality of adjacent areas, and according to the load information of the adjacent area of a plurality of adjacent areas, determine the Target cell of MLB, thereby making choosing of MLB Target cell is comprehensively more, the even running of safeguards system, and the favourable load balancing effect that reaches the whole network.
For the technical scheme providing in the invention described above embodiment is more clearly described, below in conjunction with the application scenarios of the double bounce MLB load information interaction shown in Fig. 3, the load-balancing method proposing in the embodiment of the present invention is described in detail.For convenience of description, in Fig. 3, the adjacent area of community A is community B and community D, and the adjacent area of community B is community C and community E, and the adjacent area of community D is community F, for other adjacent areas in practical application, and no longer explanation in this application scene.
As shown in Figure 4, under this application scene, this load-balancing method comprises the following steps:
Step 401, obtains the load information of adjacent area.Wherein, when load balancing need to be carried out in certain community, this community need to obtain the load information of adjacent area.The community A of take need to carry out load balancing as example, and community A need to obtain the load information of community B and community D.
Step 402, community A obtains the load difference of community B and community D according to the load information of community B and community D.Wherein, the load difference of community B and community D is at least divided into difference not quite and two kinds of situations of significant difference.When the load difference of community B and community D is difference when little, forward step 403 to, when the load difference of community B and community D is significant difference, forward step 405 to.
Concrete, in order more clearly to distinguish difference not quite and two kinds of situations of significant difference, can set in advance according to the actual needs a load threshold, when the load difference between community B and community D is less than this load threshold, illustrate that difference is little, otherwise, significant difference is described.
For example, load threshold is set to 20% of cell load, community B is identical with the load that community D can bear, if according to load information learn community B when preload be 20%, community D when preload be 25%, the load difference between community B and community D is less than 20% of cell load, is less than load threshold, and between community B and community D, difference is little.
In practical application, this load threshold is not limited to use cell load, for example, can also use community to bear the quantity of terminal, load threshold is set to 8 terminals, according to load information, learns that the current terminal of community B is 30, the current terminal of community D is 40, the load difference between community B and community D is greater than 8 terminals, is greater than load threshold, significant difference between community B and community D.Situation for other default the first load thresholds, repeats in the embodiment of the present invention no longer in detail.
Step 403, community A obtains the load information of the adjacent area of community B and community D.Wherein, the adjacent area of community B is community C and community E, and the adjacent area of community D is community F, and community A need to obtain the load information of community F, community C and community E.
Concrete, when the situation of the load difference of community B and community D is difference when little, the candidate adjacent of community A using community B and community D as self, and notifying cell B and community D report the load information of self adjacent area.
Community B is after receiving this notice, if community B has known the load information of community C and community E, the load information of community C and community E directly can be reported to community A, if community B does not know the load information of community C and community E, also need to from community C and community E, obtain load information, the load information of Bing Jiang community C and community E reports community A.For community D, processing procedure is identical with community B, the load information of community F need to be reported to community A.
Step 404, community A determines the Target cell of MLB according to the load information of community F, community C and community E.
Concrete, because the situation of the load difference of community B and community D is difference when little, in the embodiment of the present invention, according to the adjacent area of community B and community D, determine the Target cell of MLB, thereby making choosing of MLB Target cell is comprehensively more, the favourable load balancing effect that reaches the whole network.
For example, the load information of community C and community E is for there being 20 terminals need to be diverted on the B of community, and the load information of community F is for there being 5 terminals need to be diverted on the D of community, community A can be known when load is diverted to community D, more can guarantee the use of terminal in the A of community, community A determines that the Target cell of MLB is community D.If the load information of community C and community E is for there being 20 terminals need to be diverted on the B of community, and the load information of community F is upper for there being 20 terminals need to be diverted to community D, community A can select arbitrarily community D or the community B shunting of loading according to actual needs.
In practical application, according to the load information of community F, community C and community E, community A can also all be defined as the Target cell of MLB by community D and community B, thereby the load of part terminal is diverted to community D above, and the load of other-end is diverted on the B of community.
It should be noted that, this load information according to community F, community C and community E determines that the process of the Target cell of MLB can select arbitrarily according to actual needs, in the embodiment of the present invention, repeats no longer in detail.
Step 405, community A determines the Target cell of MLB according to the load information of community B and community D; Be that community A selects the community of loading condition optimum in community B and community D as the Target cell of MLB.For example, community A learns that according to the load information of community B and community D the current terminal of community B is 30, and the current terminal of community D is 40, and community A is by the Target cell of determining that community B is MLB.
Step 406, community A carries out load balancing according to the Target cell of MLB; The load that is about to need on the A of community to carry out load balancing is diverted to the Target cell of MLB.
In sum, the technical scheme that the application of the invention embodiment provides, angle from regional area, when MLB, obtain the load information of all hiding community (Hidden cell) of MLB community, avoid the demand thinking of oneself only, thereby stood in target or community that wider angle is selected MLB.And from the angle of the whole network, if each node is not the load balancing demand of self merely, but when having MLB demand, consider the even potential MLB demand in adjacent area of adjacent area of adjacent area, the effect of the load balancing of inevitable favourable the whole network more.
Wherein, can the adjusting according to the actual needs smoothly of each step in the present invention.
Visible, the method providing in the application of the invention embodiment, when the load difference between a plurality of adjacent areas is little, by considering the load information of the adjacent area of a plurality of adjacent areas, and according to the load information of the adjacent area of a plurality of adjacent areas, determine the Target cell of MLB, thereby making choosing of MLB Target cell is comprehensively more, the even running of safeguards system, and the favourable load balancing effect that reaches the whole network.
