Description

Indoor distribution base station establishing method and device

Technical Field

The embodiment of the invention relates to the technical field of communication networks, in particular to a method and a device for establishing indoor distributed base stations.

Background

Indoor distributed base station (indoor branch for short) construction is mostly applied to indoor deep coverage, and coverage scenes are mostly residential areas, administrative office areas, shopping malls, shopping centers and the like. Because 4G is a high-frequency networking, the construction of an outdoor macro base station (macro station for short) is mostly applied to outdoor wide coverage, and the coverage scene is a road, a village, a lake, a farmland and the like. Different from 2G low-frequency networking, the signal attenuation is large in the receiving process. In the construction, the coverage distance of the city, county and city macro station is only 500 meters, and the coverage distance of the rural areas and other areas is only 2000 meters, which is more than 5 times less than the 2G coverage distance. This is the main reason leading to dense site building in the 4G era.

In addition, with the rapid development of the IT industry, the use habits of users are also obviously changed, and the users not only use voice services on roads, but also use data services indoors for more time. The prior art needs both wide coverage and deep coverage in network construction. Therefore, in the 4G era, besides the dense construction of macro base stations to meet the wide coverage requirement, the mass construction of indoor distribution systems to meet the deep coverage is an important sign different from the 2G era, even in the future 5G "internet of things" or even "ten thousand networking" era, the deep coverage requirement is more prominent, and the indoor distribution system base station construction tends to enter the "blowout" period.

In the existing network construction, the deep coverage problem is usually two extremes, and one of the two extremes is that an operator usually establishes an indoor distribution system in a new building by agreement with the property before the new building is finished to complete the deep coverage of signals in the building. In this case, the new building, especially a large building, may block the peripheral macro-station signal, thereby deteriorating or preventing the peripheral signal. However, the conventional solution is to newly build a macro station or adjust various parameters of the existing macro station to perform coverage tuning. Secondly, the property owners consider the problems of investment and the like, select the development of the non-constructed areas frequently, and develop a lot of buildings in the rare lands such as cultivated land in the early stage, so that the periphery of the built buildings is not covered by any signal, and a macro station needs to be newly built to cover roads and peripheral matching.

For the situation of signal degradation around a new building caused by the construction of the new building, coverage tuning is usually performed by adjusting various parameters of existing macro stations, and the macro stations are newly built after optimization is not achieved. However, the problem of locating new stations becomes the most difficult point in the case of stations that have been built relatively densely. After a new building is built, the problem of network coverage can be solved only by newly building a macro station under the condition that related nearby accessories have no coverage. And if the new building is a large building, such as a 1000M 1100M square-shaped building. Considering that the coverage radius of the 4G urban area is only 500M, the traditional method needs at least 2 macro stations to cover the periphery of the whole square building, and in addition, the annular building also needs to consider the annular middle position, and possibly causes signal degradation or no signal due to the shielding of the annular building.

In the two situations, objective factors such as difficult site selection and complex coverage situation are eliminated, the newly built station also has the problems of long communication batch construction process and high labor cost, and meanwhile, the existing iron tower and machine room part in the construction of the macro station are completely delivered to an iron tower company, and the problems of great increase of overall construction cost, later-stage lease cost and equipment maintenance cost and the like also exist; in addition, the iron tower company belongs to different enterprises from the communication company, and has different business processes and management modes, so that time delay in equipment construction and fault maintenance is serious, user perception is poor, and complaint amount is increased.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Fig. 1 shows a schematic flow chart of an indoor distribution base station establishment method provided in this embodiment, including:

s101, determining whether a frequency band networking mode of an indoor distributed base station is adopted or not according to peripheral data of a newly-built building.

Wherein, the peripheral data of the newly-built building comprises: the method comprises the following steps of determining the type of a peripheral area of a new building, the distance between the new building and a peripheral base station, the height relationship between the new building and the peripheral building, the shape of the new building, the equipment type of a new indoor base station, transmission allocation, antenna distribution, power taking, machine room planning, and road test, measurement report data and complaint data of the new building.

The frequency band networking mode is a networking mode which is implemented according to different frequency bands so as not to influence each other.

And S102, if the frequency band networking mode of the indoor distributed base station is adopted, determining a networking frequency band according to the frequency bands of the peripheral base stations of the newly-built building.

Specifically, the frequency bands of the surrounding base stations are counted, the frequency bands already used by the surrounding base stations are not considered, and the unused frequency bands are used for networking, so that the influence of the frequency bands is prevented.

S103, if the shortest distance of the ring plane in the newly-built building is judged and known to exceed a threshold value, the networking frequency band is adopted to newly build the indoor distributed base station in the newly-built building according to the frequency band networking mode of the indoor distributed base station.

Wherein, the shortest distance of the ring plane is the shortest distance of the ring plane in the annular building, namely the shortest diameter in the circular section.

Specifically, when an indoor distribution base station is newly built in the newly built building, a newly built indoor distribution system is used as a support, macro station cells with different frequency bands are additionally installed on the main device, and the following factors are specifically considered:

1) and (5) building the surrounding environment of the building. The method is mainly divided into two types, wherein the first type is newly built in the original dense urban area, and the second type is newly built in the original uncovered area of a development area. If the original dense area is newly built, the situation of the peripheral base station is considered, and the situation is explained in 2) and the distance factor of the peripheral base station. And when a building is newly built in an area without coverage, the new building and the periphery of the building are under the condition of no coverage.

Then, when a new building is built in the original coverage-free area, there is no signal around the area, and at this time, the influence of other factors on the network is not considered for the moment, and different networking schemes for building a station by using the newly built indoor distribution system can be used, specifically, the specific example is shown in fig. 2. According to the comparison between (a) and (B) in fig. 2, if the building is less than 500M × 500M, only 4 cells are needed for different frequency band networking schemes of the base station using the newly-built indoor distribution system, as shown in fig. 2 (B); whereas the conventional networking scheme requires 2 base stations as shown in fig. 2 (a). If the area of the green belt of the building only exceeds 1000M by 1000M, then the networking scheme of the different frequency bands of the base station of the newly-built indoor distribution system only needs 8 cells, while the traditional networking scheme needs 4 base stations to complete the same-side coverage. From the aspect of cost of the traditional 4 stations, BBU equipment saves 76000 yuan, transmission line cost is 100000 yuan, the conservative estimation of field rent cost of 4 macro base stations is 100000 yuan/year, iron tower cost is 400000 yuan, construction cost of matching equipment such as an electric meter PTN and the like is about 3000 yuan, and under the same condition, only the whole investment cost of the first year can be saved by more than 70 ten thousand yuan.

2) Distance from surrounding base stations. The factor is unified with 1) new construction of a new building in an original dense urban area, the distance between the new building and a peripheral base station in the dense urban area is certainly within 500M, and the newly-built building possibly shields the periphery, so that signals of a shielded area are degraded or no signals exist. And because the distance to peripheral base stations is within 500M, the condition of newly-built outdoor macro station is not satisfied, at the moment, a networking scheme of different frequency bands of a newly-built indoor distribution system base station can be preferentially used, and a macro station cell of different frequency bands is newly built through a newly-built indoor distribution system, so that the problem of signal degradation of a shielded position is solved. At the moment, because the original dense region is, the same frequency is easy to generate interference, and the different frequency bands are recommended to be used. If peripheral base stations are mostly networked in the D frequency band, the newly-built cell can use the F frequency band, the frequency band with sufficient F frequency band resources is clean, interference can be reduced, and channel quality is improved.

3) Height of new building and peripheral building. In LTE network construction planning, an outdoor macro station with a tower height exceeding 50M is regarded as a high station, and the high station may generate handover coverage, overlapping coverage, islanding effect, etc., resulting in various network problems such as co-channel interference, poor quality, dropped calls, etc., so that base stations higher than 50M in the existing network need to be adjusted to be lower than 50M.

4) The shape of the newly built building. Special shaped buildings, such as ring buildings, may have degraded or no coverage of green belts or open spaces due to the building's circular shade. In addition, when the shortest distance of the plane of the inner ring of the building exceeds 1000M, a newly-built cell is considered to be covered, as shown in fig. 4 (a); or consider a new station to be covered, as shown in fig. 4(B) in a conventional networking manner.

In terms of cost, the traditional networking scheme needs to erect a tower in a green belt, and the cost is high. And the networking scheme of the base station of the newly-built indoor distribution system in different frequency bands only needs to add a hanging antenna on the appearance of the building. In the aspect of coverage, the traditional scheme has better overall coverage, but the scheme of networking different frequency bands of a base station by using a newly-built indoor distributed system can use a high-power antenna to make up for the problem of slightly poor coverage. In the aspect of construction, the traditional new scheme needs to lay and bury optical cables, so that the construction amount is large, the approval of an owner is difficult to obtain, and the networking scheme of the new indoor distribution system base station in different frequency bands does not need to lay and bury the optical cables, and can be realized only by using the optical cables of the nearby indoor distribution system. Therefore, on the whole, the networking scheme of different frequency bands of the base station of the newly-built indoor distribution system is more advantageous, and the effects of cost reduction and efficiency improvement are achieved.

In addition, the situation shown in fig. 4(a) and (B) is extremely extreme, and it is difficult to reach the diameter distance of 1km in the green belt or open space inside the ring-shaped building in consideration of the building cost, etc., so that it is sufficient to install the easymarco or BOOKRRU with small power, and the appearance is small and convenient to install, and is very suitable.

5) The method comprises the steps of equipment type, transmission allocation, antenna distribution, power utilization, machine room planning and the like of a newly-built indoor sub-base station.

6) And (4) acquiring road test, MR data and complaint data of the base station of the newly-built room.

Factors 5) and 6) are not much different from the traditional newly-built indoor sub-base station, and only the following three problems need to be focused:

first, the hardware host of the TDD-LTE wireless device generally consists of a bbu (building Base band unit), also called a baseband processing unit, an rru (radio Remote unit), i.e. a radio Remote unit, and an antenna feeder system. The BBU device is composed of a machine frame, a power supply module, a fan module, a UMPT (Universal Main Processing and Transmission Unit), namely a Main control Transmission single board, an LBBP (LTE base band Processing board type D) D type BaseBand Processing board or UBBP (Universal base band Processing Unit) Universal BaseBand Processing unit and a GPS module, and 6 parts, wherein the BBU device is newly built with an indoor distribution system base station different frequency band multi-band networking scheme, and BBU devices and BaseBand boards (which can be supported by common devices) for supporting multiple RRUs.

Secondly, the frequency bands supported by the indoor distribution equipment can be determined according to the configuration equipment specification, and include optional frequency bands of an RRU and an antenna feeder, such as a DRRU3182-FAD model RRU, which supports F, A, D frequency bands and does not support E frequency bands.

Thirdly, the electricity utilization condition needs to be considered when an outdoor macro station cell is newly built, and if the distance between the RRU and a mains supply exceeds 30M, a special power line needs to be purchased. Due to the power utilization particularity of the RRU, the position of a machine room needs to be reasonably planned when a networking scheme of different frequency bands of a base station of a newly-built indoor distribution system is planned, and the situation that power cannot be taken is avoided. If a 12-storey building is provided with a machine room in the first floor, a newly-built outdoor macro-station cell at about 36 meters above the 12 th floor is difficult to take power, so that the scheme cannot be implemented.

The embodiment determines a frequency band networking mode of adopting the indoor distributed base station by observing peripheral data of a newly-built building, determines a networking frequency band according to the frequency band of the peripheral base station, adopts the networking frequency band to newly-build the indoor distributed base station in the newly-built building according to the frequency band networking mode, not only can the indoor deep coverage degree be met, but also the problems of peripheral road network degradation and no coverage caused by the newly-built building of the building are solved, meanwhile, the scheme only relates to the inside of a communication company, new station batch and complex network optimization measures are not needed, when the network optimization is effectively saved, the labor cost and the investment cost are reduced, the business income is effectively improved, and the networking cost performance ratio of the network is improved.

Further, on the basis of the above embodiment of the method, the method further comprises:

and S104, determining the position of the newly-built cell of the outdoor macro station according to the height relationship between the newly-built building and the surrounding buildings.

Specifically, in LTE network construction planning, an outdoor macro station tower with a height exceeding 50M is regarded as a high station, and the high station may generate handover coverage, overlapping coverage, islanding effect, etc., resulting in multiple network problems such as co-channel interference, poor quality, dropped call, etc., so that base stations higher than 50M in an existing network need to be adjusted to be below 50M. After the new building is constructed, the specific situations are divided into three types, which are respectively shown in fig. 3(a), (B) and (C). As shown in FIG. 3(A), the surrounding building exceeds 50M, while the newly constructed building does not exceed 50M. In the second case, as shown in fig. 3(B), both the surrounding building and the newly constructed building exceed 50M. In the third case, as shown in fig. 3(C), the newly constructed building exceeds 50M and is higher than the surrounding buildings.

The first and second cases may exist before the new building is not built, and may have been solved by traditional means such as building an indoor distribution system, RRU remote, or building a macro station. If not, the solution can be solved by the networking scheme of different frequency bands of the base station of the newly-built indoor distribution system, which is roughly shown in fig. 3(a) and (B). The specific antenna hanging height and the number of newly-built cells are determined according to actual conditions.

Of the three cases, case three is the most common, and it is not discussed whether the surrounding buildings exceed 50M, because whether the surrounding buildings exceed 50M will be blocked by new buildings, which results in signal degradation or no-signal condition. In addition, due to the over-height of the building, the phenomenon of "dark under tower" is also formed for the ground roads and the bottom stores of the surrounding buildings. Therefore, when networking of different frequency bands of a base station of a newly-built indoor distribution system is implemented, road coverage needs to be considered. And newly building an outdoor macro station cell by utilizing an indoor distribution system optical cable line at a new building 20-25M, wherein the cell direction angle faces to roads and a bottom store of a peripheral building. Meanwhile, due to intensive station building, different frequency bands are used as much as possible when a cell is newly built, and phenomena such as same frequency interference and the like are avoided. As generally shown in fig. 3 (C). The specific antenna hanging height, the number of newly built cells and the antenna azimuth angle are determined according to actual conditions.

Synthesize three kinds of circumstances and say, can effectively solve the not enough problem of degree of depth coverage through newly-built indoor distribution system base station different frequency channel network deployment, and to high station problem, we can make some new technologies such as BOOKRRU and easy marco equipment, and its equipment is less easily to install, and power is less, and the coverage distance is more can effectively avoid the antenna to hang and establish the too high station problem that produces. In addition, 3D MIMO technology can be used for high-rise buildings with higher buildings at the periphery, the difference from the traditional antenna is that the vertical angle of the antenna reaches 65 degrees, and the problem that the high-rise buildings cannot be covered completely can be effectively solved. On the whole, the 'old and difficult' problem of covering complaints by some indoor partitions is an effective means for reducing complaints and improving indexes by building different frequency bands of an indoor distribution system base station for networking.

Further, on the basis of the above embodiment of the method, before S101, the method further includes:

and S100, collecting peripheral data of the newly-built building.

Particularly, data acquisition is a very important link in new planning and design, and great convenience is provided for subsequent network optimization work. The peripheral data mainly involved include: the method comprises the following steps of determining the type of a peripheral area of a new building, the distance between the new building and a peripheral base station, the height relationship between the new building and the peripheral building, the shape of the new building, the equipment type of a new indoor base station, transmission allocation, antenna distribution, power taking, machine room planning, and road test, measurement report data and complaint data of the new building.

When peripheral data are collected, firstly, the periphery of a newly-built building is determined, the periphery is mainly divided into two types, one type is newly built in an original dense urban area, and the other type is newly built in an original uncovered area of a development area. And if the new building is selected to solve the signal degradation problem through a newly built cell at the moment, the frequency band of the surrounding base station needs to be considered, and the frequency band of the dense area is easy to generate interference and suggests to use a different frequency band. When a building is newly built in an area without coverage, the building and the periphery of the building are under the condition of no coverage. Secondly, after the surrounding situation of the building is clarified, relevant data acquisition is carried out on the building, wherein the relevant data acquisition comprises the acquisition of the height of the newly-built building and the surrounding building, and the shape of the newly-built building.

The height of the new building and the surrounding buildings is 50M, and the macro station exceeding 50M is a high station in the base station planning design, namely, the outdoor area exceeding 50M is basically without signals. Conversely, if the surrounding building exceeds 50M, the surrounding signal of the newly built building may be degraded or uncovered. When the shape of the newly built building is a Chinese character 'hui' shaped 8-shaped building or a circular building, and the building center has outdoor environment in the form of outdoor open space or green belts, the green belts or the open space can be covered or uncovered due to annular shielding of the building. In addition, when the shortest distance between the green bad zone or the empty ground plane exceeds 1km, a new station is considered to be covered, as shown in fig. 5.

And finally, performing transmission allocation, antenna distribution, power taking, machine room planning and the like of the newly-built room base station, and performing conventional room construction planning such as road testing, MR data acquisition, complaint data acquisition and the like.

After the above-mentioned multi-dimensional data acquisition and resource data acquisition support are completed, as shown in fig. 6, it is further determined whether a newly-built room-based station scheme is adopted and planning analysis is performed, and if so, the project scheme is implemented and performance tracking and acceptance is performed. Accomplish one through whole each step and can solve current problem, also can compromise the newly-built scheme of indoor branch system of the problem of leaving over that probably produces in the future for newly-built indoor branch system can seamless butt joint with original network, improves marketing profit and promotes user's perception.

Further, on the basis of the above method embodiment, S103 specifically includes:

if the shortest distance of the ring plane in the newly-built building is judged and known to exceed a threshold value, the antenna feeder installation of an indoor distribution system is planned according to the shape of the newly-built building and a design drawing, the direction angle, the pitch angle, the installation longitude and latitude and the hanging height planning of the antenna feeder of the newly-built cell of the outdoor macro station are determined according to the peripheral data of the newly-built building, and the networking frequency band is adopted to newly build the cell of the indoor distribution base station in the newly-built building.

Accordingly, the method further comprises:

and S105, performing data planning on the local cell identification, the base station ID, the tracking area code TAC, the downlink frequency point, the cell identification, the physical cell identification, the uplink and downlink subframe ratio, the root sequence index and the cell radius of the newly-built cell.

Specifically, if it is determined that the shortest distance between the planes of the rings in the new building exceeds the threshold, it is necessary to newly build a cell of an indoor distributed base station in the new building, and the method specifically includes the following steps:

and A1, carrying out indoor distribution system antenna feeder installation planning according to building models and design drawings.

And A2, according to the surrounding actual conditions acquired in the step A1, newly building a cell antenna feeder for the outdoor macro station to solve the problem of no coverage and weak coverage as a direction, and planning a direction angle, a pitch angle, an installation longitude and latitude and a hanging height by combining complaints and test conditions.

And A3, considering the situation of dense stations around, and using pilot frequency as much as possible according to the frequency band situation of the nearby macro station acquired in the step A1 to avoid interference.

A4, performing data planning on the newly-built cell, including local cell identification, ENODEBID, TAC, downlink frequency points, cell identification, physical cell identification, uplink and downlink subframe ratio, root sequence index, cell radius and the like.

and S106, debugging the newly-built indoor distributed base station, and testing the network after the newly-built indoor distributed base station.

Specifically, after the new indoor distributed base station is planned, a project scheme is implemented. And implementing according to the scheme planning, after the BBU, the RRU and the antenna feeder are installed, carrying out transmission debugging, determining that an optical path is smooth, finally carrying out cell activation, and determining that the cell can be normally started without a warning. And simultaneously, carrying out room distribution test and road test by using 4G special test software, checking whether a level is weak or not, comparing an average level value and an SINR value before building a station, checking whether improvement is obvious or not, simultaneously acquiring 4G MR coverage indexes of a local base station and peripheral base stations within 3 weeks after building, 4G switching rate, call drop rate and other perception indexes, and combining user complaints, tracking and checking whether the situation before networking of the indoor distribution system base stations in different frequency bands is improved or not, dynamically adjusting an antenna feeder pitch angle and a direction angle, testing whether the quality of wide coverage and deep coverage signals is improved or not, and then issuing a verification report if the quality of the wide coverage and deep coverage signals meets the requirement of an original planning scheme, and ending the process.

In practical applications, as shown in fig. 7(a), the situation after RSRP test is performed is shown in fig. 7(B), and in combination with the step of establishing the indoor distributed base station shown in fig. 6, the specific establishment method includes the following steps:

it should be noted that this embodiment is performed on the premise that the room sub-property has signed the property agreement or can sign the property agreement.

And B1, multi-dimensional related data acquisition.

Data acquisition is a very important link in new planning and design, and a high-quality design scheme can provide great convenience for subsequent network optimization work. The method mainly comprises 6 design steps of firstly, the periphery of a new building, secondly, the distance between the new building and a peripheral base station, thirdly, the height of the new building and the peripheral building, fourthly, the shape of the new building, and fifthly, the equipment type, transmission allocation, antenna distribution, power taking, machine room planning and the like of a new indoor base station. Sixthly, collecting data such as road test, 4G MR data, complaints and the like.

And B2, collecting resource data support.

Firstly, newly building the periphery of a building: the method is newly built for the original non-coverage area in the rural area. Distance from peripheral base station: the nearest base station is a macro base station of 3km Wuqiang flag agricultural reclamation 9 branch factories. And thirdly, the height of the newly built building and the surrounding buildings is as follows: the newly-built buildings are a 15M four-layer building, two 11M three-layer buildings and a factory area with the size of 300 Mx 200 Mx 10M. Fourthly, the shape of the new building is as follows: and (5) constructing a rectangular building. And fifthly, performing conventional indoor division construction planning such as transmission allocation, antenna distribution, power taking, machine room planning and the like of the base station of the newly built room, and performing uniform field survey by acquiring data such as road test, 4G MR data, complaints and the like.

And B3, networking different frequency bands of a newly-built indoor distribution system base station.

The networking scheme of different frequency bands of the newly-built indoor distribution system base station is based on the newly-built indoor distribution system, and a newly-built scheme of macro station cells with different frequency bands is additionally arranged on the main equipment of the newly-built indoor distribution system.

And (3) building periphery: the base stations with the distance of 3km can only cover outdoors, the indoor base stations are in a no-signal state, the user needs to completely cover buildings and factories, and due to the fact that a mobile private line protocol is signed, enterprise revenue is considered, theoretically, about 3km from the base stations in the nearest distance meets the requirement of a newly-built macro station, and the newly-built macro station can be reported. However, in the practical situation, the macro station construction planning is finished in 2017, construction needs to be reported in 2018, and a user indicates that the user cannot wait for more than one year.

Distance from peripheral base station: considering that the peripheral macro station is far away, the local macro station is actually in a weak coverage area, and is difficult to receive other base station signals, the frequency band is cleaner, but considering that the receiving attenuation of the D-band signal is larger than that of the F-band signal, and the F-band signal is more far propagated than the D-band signal, the F-band signal is selected.

And thirdly, the height of the newly built building and the surrounding buildings is as follows: there is no building around the whole garden, and the highest building is the west 15M4 floor office building. Therefore, there is no occlusion or the like.

Fourthly, the shape of the new building is as follows: the building is a traditional rectangular building, and the building is compact and square.

The overall situation is shown in fig. 8(a), and the corresponding live view is shown in fig. 8 (B).

And fifthly, the new indoor branch base station can meet the requirements of planning aspects such as equipment type, transmission allocation, antenna distribution, power utilization, machine room planning and the like.

Sixthly, the data acquisition of road test, 4G MR data, complaints and the like is completed.

The whole scheme is as follows: although deep coverage work is always a key promotion project in recent years, the new building division work has the problem that the properties cannot be coordinated in all regions because the properties are difficult to coordinate, so that the deep coverage work cannot be carried out. Therefore, after the 6 data are collected, the problem points which are similar to the industrial park and cannot be deeply covered are selected, the different-site work is carried out, and the deep coverage scheme is planned.

The design scheme is as follows: e-band indoor partition construction is carried out on three buildings, namely an office building, a dormitory building and a dining room. As the plant area is designed into a simple house, the holding pole and the equipment cannot be installed, and newly-built 2F frequency band cells are designed and installed on the office building with the highest 15M for plant area coverage, the coverage distance is long, the coverage height difference is small, the signal attenuation of the simple house is large, and the high-power antenna is preferentially used. And then, newly building 1F-band cell by additionally arranging a holding pole on the top of the dining hall to perform blind compensation on the factory coverage, as shown in fig. 8 (C).

And B4, establishing networking schemes of different frequency bands of the indoor distribution system base station in a matching way.

Firstly, planning the installation of an antenna feeder, and newly building a direction angle of 135 degrees and a pitch angle of 3 degrees in a1 cell; newly building 2 cells with direction angle of 75 degrees and pitch angle of 3 degrees; newly building a direction angle 115 degrees and a pitch angle 3 degrees of the 3 cells; (the pitch angle is a default value and is dynamically adjusted in the later verification process); longitude 108.6857683 and latitude 40.79287 are installed. The antenna installation position roof holds pole, hangs height 15 meters. Firstly, the wiring planning of the transmission line is carried out according to the antenna installation position of the indoor distribution system, and the newly-built macro station cell transmission line is reserved. And thirdly, wireless side data planning, wherein the data planning for the newly-built cell is shown as the following table:

b5, project embodiment implementation.

According to the scheme, planning is started in 2017 in 6 months, and by the end of 10 months, the networking scheme of different frequency bands of the base station of the newly-built indoor distribution system finishes the batch replication of deep coverage site different addresses and the planning and verification of the design scheme thereof. Because the equipment is not delivered, the construction cannot be carried out, and therefore the follow-up work is not finished.

B6, performance tracking and acceptance.

Since step B5 is not complete, this step only completes the investment cost and revenue assessment:

the scheme has the following cost:

the RRU equipment + construction material + license + field lease is 5000 × 3+8000+15000+0 ≈ 38000.

Cost of newly building a single macro station:

BBU + district RRU equipment + service charge + license + iron tower field lease + iron tower cost 19000+5000 x 3+10000+15000+10000+80000 ≈ 139000 yuan.

Under the same condition, the money is saved by about 100000 yuan, which is 3 times of the cost, meanwhile, the labor cost of the building network optimization personnel such as the station building, the acceptance inspection, the test and the like, the time cost of the batch and repeat period, the time and labor cost of the account reporting and the building of the non-mobile personnel are not calculated, and the cost reduction and the efficiency improvement effect are outstanding. In addition, with the difference of regions, the iron tower field rent also has great changes, the inner Mongolia regional population is rare, the amount of the field rent is in the end position of the whole country, and the project is placed in the northern wide equal places, which will save the cost by 20 times or even more than 50 times.

And (3) evaluating the profit cost: the plant area has about thousands of people, and the traffic volume of a single cell 1G per day and a single cell 1erl per day is shown in the following table, which is an extremely conservative estimate, and the total annual income is about 2.6 ten thousand yuan.

Gain of	3 newly-built macro station cells of industrial park	Unit price of	Income for one year (Yuan)
				Annual average flow	1095G	15 yuan/G	16425
Traffic volume	1095erl	0.15/min	9855

In general, a new macro station cell is only built in a networking scheme of different frequency bands of a base station of a newly-built indoor distribution system, nearly 10 ten thousand yuan is saved compared with a newly-built single macro station, and meanwhile, 2.6 ten thousand yuan of economic benefit is generated. Overall, the cost is reduced, the effect is obvious, and the proposed cost performance is extremely high.

It should be noted that, the networking scheme of different frequency bands of the base station of the newly-built indoor distribution system is only specific indoor division and networking of different frequency bands of the macro station, but is not limited to a specific unit, and all networking solutions of different frequency bands of the same base station of indoor distribution base stations of indoor division frequency bands and macro station frequency bands implemented according to the national radio frequency planning are protected.

The embodiment fully uses the resources of a newly-built indoor distribution system, utilizes the prophase planning advantage of the indoor sub-base station, and effectively solves the common network problems of no signal, signal degradation, island effect, tower blackness, high-rise coverage failure and the like generated along with a newly-built building through a novel networking construction scheme that the newly-built indoor sub-base station is simultaneously compatible with a different-frequency-range outdoor macro-station cell, thereby further reducing the investment cost and improving the network quality. The scheme for networking different frequency bands of indoor distributed base stations in the process of building a new building indoor distribution system is provided, the common networking of indoor frequency bands and macro station frequency bands and the same base station can be realized more reasonably according to the situation of a new building, and the problems of network degradation and no coverage of peripheral roads caused by the new building are solved under the condition of meeting the indoor deep coverage. The proposal only relates to the inside of a communication company, does not need new station replication, does not need complex network optimization measures, effectively saves the time for network optimization, reduces the labor cost and the investment cost, effectively improves the business income, and improves the networking cost performance of the 4G network.
