Description
Technical field
The present embodiments relate to technical field of communication network, and in particular to a kind of indoor distribution base station method for building up and dress
It sets.
Background technique
Indoor distribution base station (abbreviation room point) construction is applied to indoor depth covering more, and covering scene is mostly residential block, row
Political affairs Administrative Area, market, shopping center etc..Since 4G is high frequency networking, and outdoor macro base station (abbreviation macro station) construction is applied more
In outdoor wide covering, covering scene is road, village, lake, farmland etc..It is different from 2G low frequency networking, signal was receiving
Attenuation is larger in journey.In construction, city county town macro station coverage distance is only 500 meters, and the regions such as rural area are only 2000 meters, than it
2G coverage distance has lacked more than 5 times.This is the main reason for causing the 4G epoch intensively to be built a station.
In addition, with the fast development of IT industry, user's use habit also occurs obviously to change, and user not only uses on road
Voice service, more time can use data service indoors.The prior art should be covered extensively in network construction and also want depth
Covering.Therefore, in the 4G epoch, other than intensively building macro base station and meeting wide covering demand, high-volume builds indoor distributed system
It is its important symbol for being different from the 2G epoch to meet depth covering, or even says in the following 5G " Internet of Things " or even " Wan Lian
Net " epoch, depth covering demand can be protruded more, and indoor distributed system base station construction certainly will enter " blowout " phase.
When now net construction, depth covering problem is usually two extreme, first, operator is usually before new building completion,
By establishing indoor distributed system in new building with property agreement to complete the covering of the depth of signal in building.At this point, because
For new building especially heavy construction, periphery macro station signal can be generated to block and cause ambient signal deterioration or no signal.And lead to
Normal solution is mostly newly-built macro station, or adjusts the parameters for having macro station and carry out covering tuning.Second, owner of estate considers
The problems such as investment, the non-construction area exploitation of more options, many building exploitation early periods are the unfrequented soils such as arable land, therefore
The building is built up rear surrounding and is covered without any signal, needs that newly-built macro station is mating to road and periphery covers.
The case where new building ambient signal caused by construction for new building deteriorates, usually by adjusting existing macro station
Parameters carry out covering tuning, and macro station is created after optimization has no resolution.However the new website in the case where intensively building a station relatively
Location problem becomes maximum difficult point.After building for new building, nearby related mating no coverage condition, can only pass through newly-built macro station
To solve the problems, such as the network coverage.And if new building is heavy construction, as 1000M × 1100M rectangular-ambulatory-plane is built.Consider 4G covering
Radius city is only 500M, and by the periphery covering of entire square building, conventional method needs at least two macro station just to can solve to build
The matched covering problem in periphery is built, in addition, this kind of annular building is also contemplated that annular middle position, it is possible to due to annular building
Blocking leads to Signal Degrade or no signal.
Both the above situation, removes addressing hardly possible, the objective factors such as coverage condition complexity, and newly-built station is built there is also reply is linked up
If process is longer, the high problem of human cost, while steel tower is submitted in steel tower, computer room part completely in macro station construction now
Company, the problems such as being substantially increased there is also whole construction cost, later period lease expenses, equipment maintenance cost；In addition, due to iron
Tower company adheres to different enterprises separately in communication common carrier, has different operation flow and way to manage, leads to equipment construction, failure dimension
Shield aspect time delay is serious, and user, which perceives, to be deteriorated, and complaint amount rises.

Specific embodiment
With reference to the accompanying drawing, further description of the specific embodiments of the present invention.Following embodiment is only used for more
Technical solution of the present invention is clearly demonstrated, and not intended to limit the protection scope of the present invention.
Fig. 1 shows a kind of flow diagram of indoor distribution base station method for building up provided in this embodiment, comprising:
S101, the perimeter data according to New Buildings, it is determined whether using the band networking mode of indoor distribution base station.
Wherein, the perimeter data of the New Buildings includes: the neighboring area type of New Buildings, New Buildings
With at a distance from peripheral base station, the height relationships of new building and neighboring buildings, the shape of New Buildings, newly-built room divide base station
Device type, transmission allotment, antenna distribution, electric power is taken, computer room is planned and the road test of New Buildings, measurement report
Data and complaint data.
The band networking mode is that networking mode of the networking not have an impact each other is carried out according to different frequency range.
S102, according to the band networking mode of the indoor distribution base station, then according to the periphery of the New Buildings
The frequency range of base station determines networking frequency range.
Specifically, the frequency range for counting peripheral base station, by peripheral base station, used frequency range is not considered, using not making
Used frequency range carries out networking, prevents mutual frequency range from having an impact.
If S103, judgement know that the plane of a loop shortest distance in the New Buildings is more than threshold value, according to the room
The band networking mode of interior distributed base station creates indoor distribution base station using the networking frequency range in the New Buildings.
Wherein, the plane of a loop shortest distance is the shortest distance of plane of a loop in annular building, i.e., most short in circular section
Diameter.
Specifically, when creating indoor distribution base station in the New Buildings, to be with newly-built indoor distributed system be according to
Support installs the macro station cell of different frequency range additional on its main equipment, specifically needs to consider following factor:
1) surrounding enviroment of New Buildings.Two kinds are broadly divided into, one is it is newly-built in former dense city, the second is opening
It is newly-built without overlay area to send out area's class original.Newly-built if it is former close quarters, then considering peripheral base station situation, which will be 2)
Illustrate together with peripheral base station distance factor.And in no overlay area new building, then new building and building periphery are nothings
Coverage condition.
So when original is without overlay area new building, periphery must no signal, at this point, putting aside other factors to net
The influence of network can be used newly-built indoor distributed system and build a station different networking plans, and specific comparison is as shown in Figure 2.According to fig. 2
(A) and (B) comparison uses newly-built indoor distributed system base station different frequency range if building is less than 500M*500M
Networking plan only needs 4 cells, as shown in Fig. 2 (B)；And traditional networking plan needs 2 base stations, as shown in Fig. 2 (A).Such as
The only greenbelt area of fruit building just so creates indoor distributed system base station different frequency range group more than 1000M*1000M
Net scheme only needs 8 cells, and traditional networking plan then needs 4 base stations that could complete same side covering.For traditional 4 stations
From cost, BBU equipment just saves 76000 yuan, and 100000 yuan of transmission line expense, 4 macro base station studio rent expense conservative estimations
100000/ year, about 3000 yuan of corollary equipments operating expenses such as 400000 yuan of steel tower expense and ammeter PTN etc., in square one
Under the fully invested expense of only First Year will save 700,000 yuan or more.
2) at a distance from peripheral base station.This factor and 1) new building in former dense city it is newly-built be it is unified, intensive
New building and peripheral base station distance will certainly be within 500M in city, and New Buildings are likely to cause to hide to periphery
Gear leads to be blocked regional signal deterioration or no signal.And due within 500M, being unsatisfactory for creating apart from peripheral base station
Outdoor macro station condition can pass through what is created preferentially using newly-built indoor distributed system base station different frequency range networking plan at this time
Room subsystem creates different frequency range macro station cell, solves the problems, such as the position signal deterioration that is blocked.At this time since original is close quarters,
Suggest using alien frequencies section with interference is also easy to produce frequently.If peripheral base station is mostly D band networking, then F frequency then can be used in newly-built community
Section, F-band resource abundance frequency range is clean, can reduce interference, promotes channel quality.
3) height of new building and neighboring buildings.In LTE network construction plan, outdoor macro station tower height is more than 50M view
For high station, high station may generate area covered, overlapping covering, and island effect etc. causes poor, call drop of co-channel interference, matter etc. more
Kind network problem, therefore the base station in existing net higher than 50M needs to adjust to 50M or less.
4) shape of New Buildings.Special shape building such as annular building, being blocked due to building annular may lead
Cause greenbelt or vacant lot covering deterioration or without covering.In addition, to consider as when the plane of a loop shortest distance is more than 1000M in building
Newly-built community is covered, as shown in Fig. 4 (A)；Or consider that newly-built station is covered, the tradition networking side as shown in Fig. 4 (B)
Formula.
In terms of cost, traditional networking plan needs to found tower, higher cost in greenbelt.And newly-built indoor distributed system
Base station different frequency range networking plan only needs to carry additionally antenna in architectural appearance.In terms of covering, traditional scheme is integrally covered preferably,
But high powered antenna can be used using newly-built indoor distributed system base station different frequency range networking plan to make up its covering and omit
The problem of difference.In terms of construction, traditional newly-built project needs cloth buried fiber optic cable, and construction volume is more very much not said, it is difficult to obtain owner of estate's
Approval, and newly-built indoor distributed system base station different frequency range networking plan does not need cloth buried fiber optic cable then, merely with nearest indoor point
Distribution system optical cable can be realized.Therefore, generally speaking, it is more excellent to create indoor distributed system base station different frequency range networking plan
Gesture achievees the effect that cost efficiency.
In addition, situation shown in Fig. 4 (A) and (B) is extremely extreme, consider green inside building cost etc. annular building
Change band or vacant lot be difficult to reach the diametral distance of 1km, therefore, low power easymarco or BOOKRRU installation, outside
See it is small and exquisite easy for installation, extremely be applicable in.
5) device type of room point base station is created, transmission is deployed, antenna distribution, electric power is taken, computer room is planned.
6) room is created to divide the road test of base station, MR data, complain data acquisition.
Factor 5) and 6) the considerations of and the newly-built room point base station of tradition be not much different, it is only necessary to pay close attention to following three and ask
Topic:
The hardware main equipment of first, TDD-LTE wireless device is usually by BBU (Building Base band Unit)
Also referred to as baseband processing unit, RRU (Radio Remote Unit) i.e. Remote Radio Unit and antenna feeder decorum composition.And
BBU equipment is then by machine frame, power module, blower module, UMPT (Universal Main Processing&
Transmission unit) i.e. master control transmit veneer, LBBP ((LTE BaseBand Processing board type d) D
Type LTE Baseband Processing Unit or the general baseband processing unit of UBBP (Universal BaseBandProcessing unit) and
GPS module, totally 6 parts form.Newly-built indoor distributed system base station different frequency range networking plan, needs support the more RRU of multiband
BBU equipment and baseband board (general device can be supported).
Second, for room subset support frequency range can according to configuration equipment specification determine, including RRU, antenna feeder can
The frequency range of choosing supports F, A, D frequency range such as Huawei DRRU3182-FAD model RRU, does not support E frequency range etc..
Third will consider electricity consumption situation in newly-built outdoor macro station cell at this time, if RRU is more than 30M apart from mains supply,
It then needs to purchase power source wire.Due to the electricity consumption particularity of RRU, newly-built indoor distributed system base station different frequency range group is being planned
Will make rational planning for Host equipment room when net scheme, and electric situation can not be taken by avoiding the occurrence of.Such as 12 layers of high building, machine is set in Stall
Cause scheme that can not implement then creating outdoor macro station cell at about 36 meters of 12 roofs will be difficult to take electricity in room.
The present embodiment determines the band networking using indoor distribution base station by investigating the perimeter data of New Buildings
Mode determines networking frequency range according to the frequency range of peripheral base station, and uses networking frequency range in new building according to band networking mode
Create indoor distribution base station in object, be not only able to satisfy indoor depth coverage, and solve because building it is newly-built caused by week
By-pass road network deteriorates and without covering problem, while this programme only relates to inside communication common carrier, without new website reply and complexity
Network optimization measure, the effectively save network optimization used time, reduce human cost and cost of investment, effectively promote business and receive
Enter, improves the networking cost performance of network.
Further, on the basis of above method embodiment, the method also includes:
S104, according to the height relationships of the New Buildings and surrounding building, determine outdoor macro station newly-built community
Position.
Specifically, in LTE network construction plan, outdoor macro station tower height is more than that 50M is considered as high station, and high station may generate
Area covered, overlapping covering, island effect etc. lead to the multiple networks problems such as the poor, call drop of co-channel interference, matter, therefore in existing net
Base station higher than 50M needs to adjust to 50M or less.After new building is built well, concrete condition is divided into three kinds, respectively such as Fig. 3
(A) shown in (B) (C).Situation one is shown as shown in Fig. 3, and surrounding buildings are more than 50M, and new building is less than 50M.Situation two is such as
Shown in Fig. 3 (B), surrounding buildings and new building are more than 50M.For situation three such as shown in Fig. 3 (C), new building is more than 50M and ratio
Neighboring buildings want high.
Situation one, situation two are possible to i.e. existing before new building is not built, it is possible to pass through newly-built indoor point
Distribution system, RRU zoom out or create the solution of the traditional means such as macro station.If unresolved then newly-built indoor distributed system can be passed through
Base station different frequency range networking plan solves, substantially as shown in Fig. 3 (A) and (B).Specific antenna is hung high and newly-built community number and is needed
Depending on actual conditions.
In three kinds of situations, situation third is that most common, do not discuss at this time neighboring buildings whether more than 50M because no matter
Whether neighboring buildings will all be blocked more than 50M by new building, and then generate Signal Degrade or no signal situation occur.This
Outside, since building is excessively high, to the bottom shops of surface road and neighboring buildings, it also will form " black under tower " phenomenon.Therefore,
Road coverage condition is taken into account when the different frequency range networking of newly-built indoor distributed system base station is implemented.It is sharp at new building 20-25M
With the newly-built outdoor macro station cell of indoor distributed system lightguide cable link, cell deflection should be towards road and neighboring buildings bottom door
Shop.Simultaneously because intensively build a station, phenomena such as when newly-built community uses different frequency range as far as possible, avoids co-channel interference generation.Substantially such as
Shown in Fig. 3 (C).Specific antenna hangs high and newly-built community number and antenna azimuth need to be depending on actual conditions.
For comprehensive three kinds of situations, depth can effectively be solved by newly-built indoor distributed system base station different frequency range networking
Insufficient problem is covered, and is directed to high station problem, we can make some new technologies such as BOOKRRU and easymarco equipment,
Equipment is smaller to be easily installed, and power is smaller, and coverage distance is relatively close it is possible to prevente effectively from antenna hangs high station that is excessively high and generating
Problem.3DMIMO technology, difference and traditional antenna, antenna can be used further for the higher high-rise of neighboring buildings
Vertical angle reaches 65 °, can effectively solve the problems, such as that skyscraper can not all standing.Generally speaking, some rooms point are covered
The long-standing problem that lid is complained is to build a kind of effective reduction of indoor distributed system base station different frequency range networking to complain, and is mentioned
Rise the means of index.
Further, on the basis of above method embodiment, before S101, further includes:
The perimeter data of S100, the acquisition New Buildings.
Specifically, data acquisition is a very important link in newly-built planning and designing, can be excellent to subsequent network
Chemical industry is made to provide huge convenience.Its perimeter data related generally to includes: the neighboring area type of New Buildings, builds
Build object at a distance from peripheral base station, the height relationships of new building and neighboring buildings, the shape of New Buildings, newly-built room divide base
The device type stood, transmission allotment, antenna distribution, electric power is taken, computer room plan and the road test of New Buildings, is measured
Data reporting and complaint data.
When acquiring perimeter data, clear New Buildings periphery is first had to, is broadly divided into two kinds, one is former close
It is newly-built to collect city, the second is newly-built without overlay area in development zone class original.With peripheral base station distance, the new building in dense city
It is likely to peripheral base station distance within 500M and generates block, lead to the regional signal deterioration that is blocked, if selected at this time
The frequency range that peripheral base station is considered when solving signal deterioration problem by newly-built community, due to being that close quarters are dry with being also easy to produce frequently
It disturbs suggestion and uses alien frequencies section.And in no overlay area new building, then can build and build periphery is no coverage condition.Its
It is secondary, after the situation of clear building periphery, relevant data acquisition, including new building and neighboring buildings height are carried out to building
The acquisition of degree and New Buildings shape.
New building and neighboring buildings height are boundary with 50M, and the macro station in base station planning design being more than 50M is height
It stands, that is to say, that outdoor more than 50M or more is substantially no signal.Conversely speaking, if neighboring buildings are more than 50M, it is possible to lead
Cause the deterioration of new building ambient signal or without covering.New Buildings shape, if it is rectangular-ambulatory-plane 8-shaped building or circle
Building and Center for Architecture have family the forms such as outer vacant lot or greenbelt outdoor environment when, being blocked due to building annular may
Greenbelt or vacant lot is caused to cover deterioration or without covering.In addition, being wanted when green bad band or the vacant lot plane shortest distance are more than 1km
Consider that newly-built station is covered, situation as shown in Figure 5.
Finally, being then the transmission allotment of newly-built room point base station, antenna distribution, electric power is taken, computer room plans the road Deng Ji drive test
Construction plan is divided in the conventional rooms such as examination, MR data, complaint data acquisition.
After completing above-mentioned multi-dimensional data acquisition and acquisition resource data support, as shown in fig. 6, further including judging whether
Using newly-built room point base station scheme and planning application is carried out, if it is, the implementation of progress project alternative and performance are tracked and tested
It receives.Completing one by whole each step both can solve existing issue, can also take into account the leftover problem for being possible to generate in the future
Room subsystem newly-built project enables and creates room subsystem and legacy network seamless interfacing, improves marketing profit improvement user
Perception.
Further, on the basis of above method embodiment, S103 is specifically included:
If judgement knows that the plane of a loop shortest distance in the New Buildings is more than threshold value, according to New Buildings
The antenna feeder installation of shape and design drawing planning indoor distributed system, determines according to the perimeter data of the New Buildings to outdoor
