Detailed description of the invention
As stated in the Background Art, current load-balancing technique only allows for the loading condition of this community and adjacent cell, and does not consider those channel situation because being forced switching user needed for load balancing。These users are forced from after Serving cell switches to Target cell, and wireless signal will certainly decline to some extent, and then causes that customer service perception declines。If two cell powers are adjusted by base station, so as to coverage changes along with the change of Serving cell residing for edge customer, it will when not changing loading condition, improve the wireless channel environment of edge customer further。
In order to overcome such defect, the embodiment of the present invention proposes a kind of load-balancing method automatically adjusting covering based on community, on existing load-balancing technique, add the function that cell power is adjusted automatically, the coverage making neighbor cell can be adjusted correspondingly according to different loading levels, so that because load balancing needs the user that switches over, being still in relatively good channel circumstance。
As it is shown in figure 1, for the schematic flow sheet of the proposed a kind of load-balancing method automatically adjusting covering based on community of the embodiment of the present invention, the method specifically includes following steps:
Step S101, when the load of cell-of-origin reaches load balancing handoff threshold, source cell base station determines that in the edge customer meeting switching position thresholding needs switch to the edge customer of described Target cell。
In concrete application scenarios, this step also includes before performing:
The resource status that described source cell base station periodically sends according to other cell base stations updates, it is determined that sends and meets the Target cell that community is edge customer switching that the base station of pre-conditioned resource status renewal belongs to。
Needing to illustrate, proposed " other communities " of this example is specially has the community of neighboring BS relationship with cell-of-origin。
In this step, when the load of cell-of-origin reaches load balancing handoff threshold, the loading condition of all communities with it with neighboring BS relationship around can be inquired in cell-of-origin, respective loading condition (namely resource status updates) also can be informed in these communities always to the cell-of-origin of this overload, and cell-of-origin can select to carry out the Target cell of load balancing in those communities allowing load to enter。
The concrete rule that selects can be (specifically can include resources occupation rate according to the loading condition that each community is current; and/or surplus resources total amount etc.); can also be according to physical distance etc. actual between cell-of-origin and each community; concrete which kind of rule of employing can need determine according to real system, and such change can't affect protection scope of the present invention。
In actual application scenarios, described resource status updates, and triggers especially by the following manner:
When the loading that described cell-of-origin is current reaches resource reporting thresholding, described source cell base station sends resource status request to other cell base stations；
Described source cell base station is after receiving the resource status response that other cell base stations return, and the resource status that other cell base stations of periodic receipt send updates；
When the current loading in described cell-of-origin is lower than resource reporting thresholding, described source cell base station notifies that other cell base stations stop sending resource status and update。
On this basis, the concrete execution process of this step is as follows:
The measurement report that described source cell base station reports according to the described edge customer meeting switching position thresholding, it is determined that the positional information corresponding to each edge customer；
The described source cell base station resource state information according to described positional information and described Target cell, it is determined that need to switch to the edge customer of described Target cell。
Step S102, described source cell base station need the edge customer switching to described Target cell to switch to described Target cell by described。
Concrete, the concrete execution process of this step is as follows:
Described source cell base station sends handover request to described target cell base station；
Described source cell base station receives the Handover Request Acknowledge that described target cell base station returns；
Described source cell base station sends switching to the described edge customer needing to switch to described Target cell and starts instruction。
Step S103, be there is a need to switch to after the edge customer of described Target cell completes to switch in the instruction of described source cell base station, described source cell base station reduces the cell reference signals power of self, simultaneously, target cell base station raises self cell reference signals power, so that the described edge customer that be there is a need to switch to described Target cell is within the signal cover of described Target cell。
Compared with prior art, the technical scheme that the embodiment of the present invention is proposed has the advantage that
The technical scheme proposed by applying the embodiment of the present invention, cell-of-origin reduces the cell reference signals power of self after the switching carrying out edge customer, Target cell then raises the cell reference signals power of self, thus, the signal of cell-of-origin can reduce along with cutting out of edge customer, and the signal of Target cell can raise along with the incision of new edge customer, so, the two community is while proof load is constant, automatically have adjusted respective coverage, make because of load balancing needs, these edge customers of Target cell are switched to from cell-of-origin, the signal that Target cell is higher can be received when invariant position, and reduce the garbage signal intensity of cell-of-origin, optimize these wireless channel environments being switched user, improve customer service perception。
Below, in conjunction with concrete application scenarios, the technical scheme that the embodiment of the present invention is proposed is illustrated。
Concrete operation principle schematic diagram is as follows:
As shown in Fig. 2 A to 2D, for the schematic diagram of the application scenarios of the proposed a kind of load-balancing method automatically adjusting covering based on community of the embodiment of the present invention。
As shown in Figure 2 A, when community A transships, base station can attempt to switch to the user being in cell edge the community B that load is relatively low。
As shown in Figure 2 B, after edge customer switches to community B, this user is just in the middle of the covering of community B, but now still has stronger community a-signal in this position, causes that the wireless environment of this user declines to some extent。
As shown in Figure 2 C, after edge customer completes switching, if the power of self can be adjusted by community A automatically, reduce coverage, then when not affecting load, the interference to edge customer can be reduced, such that it is able to allow edge customer better receive the signal of community B。
As shown in Figure 2 D, by shifting mode, A, B Liang Ge community adjusts coverage automatically, ultimately forms stable state situation。
As it is shown on figure 3, for the schematic flow sheet of the load-balancing method automatically adjusting covering based on community under the proposed a kind of concrete application scenarios of the embodiment of the present invention, specifically include following steps:
Step S301, community A base station eNB B from base station eNB A to community B send resource status request (ResourceStatusRequest)。
In cell a, along with user is continuously increased, the loading in the A of community is gradually increased。When loading reaches resource reporting thresholding, community A starts to send ResourceStatusRequest to community B, sets up and the annexation of community B with this, and inquires its current loading condition to community B。
Step S302, eNBB send resource status response (ResourceStatusResponse) to eNBA。
Community B, after receiving resource status request, sends ResourceStatusResponse to community A, confirm with the connection establishment success of community A complete to initialize。
Step S303, eNBB periodically send resource status and update (ResourceStatusUpdate) to eNBA。
After the connection establishment success completing of community B and community A initializes in step s 302, community B will report ResourceStatusUpdate, the loading condition that reporting cell B is current to community A always。
Meanwhile, ResourceStatusUpdate switches over, as community A, the Main Basis selecting community。If the load of community B is lower than the community A handoff threshold arranged, then community A can select community B as the Target cell of switching。If the load of community B is higher than the community A handoff threshold arranged, then community A will not be selected into handoff list community B。When the load of community A is lower than when reporting thresholding, community A just can pass through resource reporting request and inform that community B stops reporting resource status to update。
Step S304, when the load of community A continues to increase and after arriving load balancing handoff threshold, the edge customer in the A of community can be reported by the positional information thresholding that base station configures。
Positional information thresholding is mostly configured to terminal measurement and obtains the difference of this community RSRP and adjacent cell RSRP。When the user being in edge meets after positional information reports thresholding, these users can pass through measurement report (MeasurementReport) and report the positional information of self。
So, the community A MeasurementReport according to ResourceStatusUpdate described before and edge customer, in that case it can be decided that by which user is switched to which community, in order to alleviate the loading condition of oneself。Such as, when the signal intensity of signal intensity and community A that one of them user measures community B meets the thresholding of reporting position information, this terminal Hui Gei community A reports the positional information of self, the ResourceStatusUpdate that community A was sent by the community B cycle, after thinking that community B meets load balancing switching condition, this user can be switched to community B。
Concrete handoff procedure such as step S305 is to shown in step S306。
Step S305, eNBA send handover request (HandoverRequest) to eNBB。
Step S306, eNBB return Handover Request Acknowledge (HandoverRequestAcknowledge) to eNBA。
Step S307, eNBA send switching to UE and start instruction (HandoverStart)。
When A base station, community by meet handoff threshold edge customer force switch to community B after, along with the reduction of self loading, gradually form stable state, will not Zai Jiangzhe community user force switch to community B。Now, for having been switched to the edge customer of community B before, channel circumstance is also bad。Reason is in that these edge customers factor such as signal intensity (RSRP, SINR) residing for self, should be in after attachment in the coverage of community A, but owing to the reason of community A overload is forced to switch to community B, and the reason of unprovoked wireless signal switches。Therefore, although these edge customers after switching are in the B of community, but remain able to receive stronger community a-signal, cause the SINR of these users to have and reduce in various degree, cause that quality of service declines。
Step S308, after eNBA indicates all edge customers to complete switching, automatically self cell reference signals power is reduced。
Meanwhile, because there being new edge customer to enter community B, community B performs step S308 further。
The cell reference signals power of self is also raised by step S309, eNBB。
So, the signal of community A can reduce along with cutting out of edge customer, the signal of community B can raise along with the incision of new edge customer, so the two community can while proof load be constant, automatically have adjusted respective coverage so that because load balancing needs, switch to these users of community B from community A, B higher signal in community can be received when invariant position, and reduce the garbage signal intensity of community A。Thus, optimize the wireless channel environment of these users, improve customer service perception。
