Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is the C-RAN network plan method flow chart of the embodiment of the present invention, as shown in Figure 1, which comprises
Step S01, the overlapping coverage that RRU concentrates each other RRU of RRU is obtained.
LTE is as a kind of same display system, and overlapping covering bring interference generates strong influence to network performance between RRU,
The definition of overlapping coverage areas is the region there are the level intensity of two or more cells more than cell-edge, should
The throughput in region due to co-channel interference influence and degradation.Overlapping coverage areas certainly exists, it may ensure that net
The seamless coverage of network, mobile subscriber can normally be switched and gravity treatment；But excessive overlapping covering can bring harm,
Such as the problems such as area covered, alternate covering, overlapping covered interior interference is the main reason for LTE throughput declines.
It is planned in order to more preferable the RRU in C-RAN network and BBU, RRU is introduced in the embodiment of the present invention
Between overlapping coverage concept, overlapping coverage is that minizone is overlapped to covering to influence an index of situation quantization, fixed
Justice is adjacent within differing 6dB with main serving cell for RSRP value in the measurement report (Measurement Report, MR) of sampled point
The ratio of the total sampling number of sampling number Zhan in area, such as making RRU1 from the collected all MR data of background server
Sampling number for main serving cell is 10000, is using RRU2 as the sampling number of adjacent area in this 10000 MR data
5000, it is 3800 that the RSRP value of RRU2, which differs the sampling site number within 6dB with the RSRP value of RRU1, in this 5000 MR data,
Then the RRU2 is 38% for the overlapping coverage of RRU1.
By acquiring a large amount of MR data, the available RRU in preservation is concentrated, using each RRU as main serving cell
When other RRU overlapping coverage, to obtain an overlapping coverage table, such as shown in table 1 below:
Step S02, other RRU that the overlapping coverage is higher than default coverage threshold value are labeled as to the phase of the RRU
Adjacent RRU.
Coverage height is overlapped between RRU, the interference represented between RRU is big, Signal to Interference plus Noise Ratio SINR can be reduced, to reduce downloading speed
Rate, the embodiment of the present invention are attributed to the same submanifold by the way that minizone is overlapped the high RRU of coverage and are used to plan BBU, so as to
To realize wireless cooperation between RRU, overlapping coverage is substantially reduced, promotes network quality.
By the way that coverage threshold value, such as 20% is arranged, classify between the overlapping relation RRU.If the overlapping covering
Degree is higher than preset coverage threshold value, then the RRU as adjacent area can be labeled as to the adjacent of the RRU as main serving cell
RRU。
By taking the table 1 as an example, using the RRU2 as when main serving cell, obtain RRU1, RRU3, RRU4 and RRU5 for
The overlapping coverage of RRU2 is respectively 41%, 54.1%, 8.5%, 18.3%, it is seen that the adjacent area more than coverage threshold value is
The RRU1 and RRU3 is labeled as the adjacent R RU of RRU2 by RRU1 and RRU3 at this time.
Step S03, it is concentrated from the RRU and chooses a RRU as main RRU.
It is concentrated from the RRU of preservation and chooses one of RRU as main RRU, and start the rule of progress submanifold according to the main RRU
It draws.
If between step S04, described main RRU adjacent R RU corresponding with RRU concentration and any two are adjacent
It is all satisfied preset distance threshold between RRU, then the RRU and adjacent R RU are combined into a submanifold.
The adjacent R RU for finding the main RRU, the i.e. RRU labeled as the adjacent R RU of the main RRU are concentrated in the RRU.
According to the geographical location of each RRU, calculates separately the distance between these adjacent Rs RU and main RRU and any two are adjacent
The distance between RRU, and be compared respectively with preset distance threshold, such as 350m.If above-mentioned calculated distance is equal
Less than the distance threshold, then the main RRU RRU adjacent thereto is combined into a submanifold.
By taking the table 1 as an example, it is seen that the adjacent R RU of RRU4 is RRU3, RRU5, RRU6, RRU7 and RUU8.If described
For RRU3, RRU4, RRU5, RRU6, RRU7 and RUU8 mutual distance within 350m, then determining can be by these RRU
It is combined into a submanifold.If the distance between the RRU3 and RRU4 surpass for 400m, it has been more than distance threshold, has then needed RRU3
It is rejected from submanifold, a submanifold is combined by RRU4, RRU5, RRU6, RRU7 and RUU8.If the only described RRU5 and RRU7 it
Between distance be more than distance threshold, then the overlapping coverage for both needing to compare, as seen from the above table, overlapping of the RRU5 to RRU4
Coverage is 38.2%, and RRU7 is 46% to the overlapping coverage of RRU4, then rejects the RRU5 from submanifold, is retained
RRU7；It can also be compared, be retained by the distance between the two and RRU4 compared between RRU7 certainly for RRU5
That adjacent R RU being closer.The going or staying mode of RRU can carry out according to the actual needs in specific judgement and submanifold
Judgement, is not specifically limited herein.
Step S05, the RRU in the submanifold is concentrated from RRU and is rejected, then concentrated in remaining RRU and choose from the RRU
Next RRU is not the adjacent R RU of other RRU between the RRU concentrates remaining RRU as main RRU.
After obtaining a submanifold, the RRU in submanifold is concentrated from RRU and is rejected, then concentrates remaining RRU from RRU again
Middle another RRU of selection carries out the combination of submanifold as main RRU.Such as it can be with after first time chooses RRU1 as main RRU
It obtains RRU1 and RRU2 group is combined into a submanifold, then RRU1 and RRU2 is concentrated from RRU and rejected, it is new for can further choosing RRU3
Main RRU carry out submanifold combination.
Between institute RRU concentrates remaining RRU be other RRU adjacent R RU until.By taking the table 1 as an example, if institute
It states RRU and concentrates remaining RRU5 and RRU15, it is seen that RRU3 and RRU15 is not the adjacent R RU of other side, to end it is considered that submanifold
Combination it is so far.
The embodiment of the present invention concentrates the neighbouring relations of each RRU by obtaining RRU, thus in conjunction with mutual distance
The RRU RRU concentrated is divided into multiple submanifolds, facilitates the planning of BBU, is thereby reduced anti-interference between RRU
Effect improves spectrum efficiency function.
Fig. 2 is another C-RAN network plan method flow chart of the embodiment of the present invention, as shown in Fig. 2, in the step
After S04, the method also includes:
If the RRU quantity in step S041, the described submanifold is greater than preset submanifold amount threshold, chosen from adjacent R RU
Select adjacent R RU one submanifold of composition being closer to the RRU distance for meeting the submanifold amount threshold.
Since the performance of BBU is different, the RRU quantity that each BBU can be connected is limited, so in submanifold
RRU quantity needs to be defined according to the actual needs.Submanifold amount threshold, such as 6 can be preset, then by described
The submanifold obtained after step S04, whether RRU quantity included in the submanifold for needing first to judge is more than the submanifold quantity
Threshold value, if being more than the submanifold amount threshold, needing to reject part RRU from submanifold makes it meet the submanifold quantity threshold
Value.For how to select the method for needing the RRU rejected to have very much, can also lead to by comparing mutual distance
It crosses and compares overlapping coverage to be selected, one such mode is only provided in the embodiment of the present invention and is illustrated.
It is respectively compared the distance between each adjacent R RU and main RRU, is picked out from adjacent R RU and meets the submanifold number
The adjacent R RU of amount threshold value being closer to the main RRU distance forms a submanifold.Even submanifold amount threshold is 6, then from master
5 adjacent R RUs nearest from main RRU are picked out in the adjacent R RU of RRU to form submanifold, and remaining adjacent R RU is eliminated
It goes.
The embodiment of the present invention keeps the planning of BBU more reasonable by the limitation to RRU quantity in submanifold, flexibly, facilitates
The planning of BBU thereby reduces the anti-jamming effectiveness between RRU, improves spectrum efficiency function.
Fig. 3 is the another C-RAN network plan method flow chart of the embodiment of the present invention, as shown in figure 3, after step S05,
The method also includes:
Step S06, at least cluster will be combined by two submanifolds, wherein existing between the RRU that each submanifold in the cluster includes
Neighbouring relations.
Through the foregoing embodiment, the RRU RRU concentrated is divided into multiple submanifolds, for planning BBU, then may be used also
Using by these submanifold recombinants as cluster, for planning the pond BBU, so that the RRU for being attributed to the same pond BBU can be by the pond BBU
In virtual baseband processing unit focus on the data of connected RRU.
In obtained all submanifolds, inquiring the RRU that the RRU that each submanifold includes includes with other submanifolds whether there is phase
Whether adjacent relationship is adjacent R RU, if so, determining that the submanifold group with neighbouring relations the same cluster can be combined into.With table
For 1, if RRU1 and RRU2 group is combined into submanifold 1, RRU3-RRU8 group is combined into submanifold 2, RRU9 and RRU10 group is combined into son
RRU11-RRU16 group is combined into submanifold 4 by cluster 3.The adjacent R RU for being RRU2 in submanifold 1 by the RRU3 in submanifold 2 known to table 1,
RRU9 is the adjacent R RU of RRU6 in submanifold 2 in submanifold 3, the adjacent R RU of RRU9 in the RRU11 submanifold 3 in submanifold 4, it is possible thereby to
Determine, the submanifold 1, submanifold 2, submanifold 3 and submanifold 4 can be together to form a cluster, for planning the pond BBU, i.e. RRU1-
RRU16 is attributable to the pond BBU.
Since the processing capacity in the pond BBU is limited, wrapped so being also required to one cluster amount threshold of setting to limit in each cluster
The RRU quantity for including in the submanifold quantity contained either each cluster.It can specifically set, not make herein according to the actual needs
It is specific to limit.
If submanifold has been more than the cluster amount threshold in cluster obtained in through the foregoing embodiment, son again may be by
Mutual distance or neighbouring relations carry out the going or staying of submanifold in determinant between cluster.
The embodiment of the present invention is by will have the submanifold group of neighbouring relations to be combined into cluster, thus facilitate the planning in the pond BBU, into
And the anti-jamming effectiveness between RRU is reduced, improve spectrum efficiency function.
Based on the above embodiment, further, the step S03 specifically:
The quantity of adjacent R RU is concentrated in RRU according to the RRU, is successively concentrated from the RRU choose RRU work from high to low
For main RRU.
Concentrated from RRU the mode for choosing main RRU and sequence can there are many kinds of, overlapping that can be mutual according to RRU
Coverage selects, and can also be selected according to situation in RRU mutual distance set, the embodiment of the present invention is therein one
Kind way of example.
By being compared to each RRU in the adjacent R RU quantity that RRU is concentrated, successively concentrated from high to low from the RRU
RRU is chosen as main RRU.It is exemplified by Table 1 and is illustrated, it can be seen that the adjacent R RU quantity of each RRU is most from table 1
It is RRU4, shares 5 adjacent R RU, so RRU4 is carried out submanifold combination as main RRU, the RRU3-RRU8 group is combined into
Then RRU3-RRU8 is concentrated from RRU and is rejected by one submanifold, table 1 is changed into such as the following table 2 at this time:
Again from table 2 more each RRU adjacent R RU quantity, at this time the adjacent R RU quantity of visible RRU12 and RRU13 be
3 at most, can select one from RRU12 or RRU13 at this time and combine as new main RRU submanifold.
Further, the method also includes:
The identical RRU of at least two adjacent R RU quantity if it exists, then calculate separately each RRU and corresponding adjacent R RU
Between average distance, preferentially select the lesser RRU of average distance as main RRU.
The identical RRU of at least two adjacent R RU quantity if it exists, then can by each RRU and corresponding adjacent R RU it
Between distance or all adjacent R RU overlapping coverage come select one of them for main RRU carry out submanifold combination.The present invention is real
Applying example is one such citing.By taking table 2 as an example, the adjacent R RU quantity of the RRU12 and RRU13 are all 3, are just needed at this time
Compare the average distance between the average distance between RRU12 RRU adjacent thereto and RRU13 RRU adjacent thereto, it is preferential to select
The lesser RRU of average distance carries out submanifold combination as main RRU.
The embodiment of the present invention, which is concentrated by comparing the quantity of adjacent R RU from RRU, selects main RRU preferentially to carry out submanifold group
It closes, so that the combination of submanifold is more reasonable, facilitates the planning of BBU, thereby reduce the anti-interference effect between RRU
Fruit improves spectrum efficiency function.
Based on the above embodiment, further, the method also includes:
Remaining RRU is attributed to the submanifold that the RRU quantity for including is not up to submanifold amount threshold one by one, wherein the submanifold
In contain at least one RRU there are neighbouring relations with remaining RRU.
Through the foregoing embodiment, after the RRU concentrated to the RRU has carried out submanifold combination, the RRU is concentrated may be also
Meeting residue is a certain number of not mutually to be the RRU of adjacent R RU, so can not use the method for above-described embodiment will be therein any
RRU carries out submanifold combination as new main RRU.But if after remaining each RRU is carried out separately as a submanifold
Continuous BBU planning, will cause the waste of resource.
Remaining RRU can be included into the submanifold for being also not up to submanifold amount threshold in order to avoid wasting, wherein institute
It states and contains at least one RRU in submanifold there are neighbouring relations with residue RRU, that is, containing at least one RRU is the adjacent of residue RRU
The RRU or adjacent R RU for containing at least one RRU is remaining RRU.
In addition, in order to so more abundant that utilize resource, if there are neighbouring relations between the RRU that two submanifolds include, and
The RRU quantity that includes in two submanifolds and it is not above the submanifold amount threshold, equally also can be combined into a submanifold.
Certainly remaining RRU is either included into a submanifold or two submanifold merging groups is combined into a new submanifold,
Require to meet the mutual distance of RRU all in submanifold no more than the distance threshold.
The embodiment of the present invention is by being attributed to the submanifold with neighbouring relations for remaining RRU, so that more reasonable obtain
Submanifold is divided, facilitates the planning of BBU, thereby reduces the anti-jamming effectiveness between RRU, improve spectrum efficiency function.
Based on the above embodiment, further, the method also includes:
If can not be with other RRU by transmission route arrival, by the RRU from the son comprising RRU in the submanifold
It is rejected in cluster.
Since the construction of RRU exists successively, and the geographical environment of various regions and transmission situation are also different, it is possible that meeting
There is the case where RRU can not reach other RRU by transmission route, just needs to eliminate these RRU from submanifold at this time.
In the actual operation process when carrying out submanifold combination through the foregoing embodiment, it is also necessary to meet some other
Condition, such as need to meet following principle for the planning deployment of C-RAN:
(1) physical site in the region C-RAN requires continuous covering, not form " flower arrangement " networking.
