Description

A kind of many nets merge method of supplying power to and network

Technical field

The present invention relates to power supply technique field in the communications field, particularly, relate to many nets and merge method of supplying power to and network.

Background technology

In-door covering is the important component part of overall wireless network, builds indoor distributed system and is conducive to absorbing telephone traffic, promote user awareness, strengthen user's viscosity.Under the business development background that four nets merge, below GSM(can be called for short 2G), below TD-SCDMA(can be called for short TD or 3G), below TD-LTE(can be called for short 4G), WLAN possesses different covering powers and business scenario, by long-term co-existence.The design of many technology indoor distributed system needs to consider as a whole, how to make compartment system resource obtain fully, reasonably utilizing, avoids overlapping construction, repeats to construct and influence each other between system the problem becoming and need to think better of.

(1) construction of indoor distributed system will be considered GSM, TD-SCDMA, TD-LTE, WLAN tetra-as a whole and net the target merged, and considers that the factor such as WLAN large scale deployment and LTE introducing is on the impact of distributed architecture, avoids the later stage frequently to change in advance.

(2) various factorss such as network capacity, system interference, resource situation, construction difficulty, cost of investment should be considered and select best construction mode.

(3) design principle of compartment system under existing each technology standard should be followed, and meet the design objective of respective system.

(4) well-designed compartment system topological structure is answered, take into full account the impact of New Schemes, be convenient to the introducing of new system: with the technical conditions of TD-SCDMA standard to determine subregion, sub-clustering is determined with the technical conditions of WLAN standard, make the adjustment of compartment system local as far as possible sub-clustering or subregion among a small circle in carry out, avoid adjusting greatly the topological structure of whole system when introducing new technology.

(5) build the in-door covering that the property point of indoor distributed system should be able to ensure high-quality, will control indoor signal simultaneously well, avoid outdoor formation strong jamming.

(6) compartment system construction should consider the interference between multisystem, especially pays close attention to the antenna isolation of indoor LTE and WLAN, and the AF panel index of multisystem mixing device.

(7) indoor distributed system should carry out mould survey according to the frequency range of WLAN and lay antenna point, and adopts the principle of " multiple antennas, small-power " to build, and electromagnetic radiation must meet country and communications industry relevant criterion.

(8) only carried out to the website of GSM construction early stage, when introducing wlan system, first benefit point is carried out to the region that former gsm system does not reach WLAN coverage effect, then feed-in WLAN signal, then high to WLAN capacity requirement key area lays separately AP and carries out Networking Design.

(9) appeared to the website of GSM+TD-SCDMA scheme early stage, when feed-in wlan system, first to former GSM+TD-SCDMA system feed-in WLAN signal, then weak-strong test or the high key area of capacity requirement are covered to WLAN and lay separately AP and carry out Networking Design.

It should be noted that, four net Combined design schemes are for wlan system, in principle will in feed-in mode, the principle that key area (meeting room, multifunctional hall etc.) lays separately is considered, switch is mainly installed in machine room or Vertical Shaft for Light-Current, mainly be installed on during AP feed-in in machine room, Vertical Shaft for Light-Current, when AP lays separately, main cloth is placed in the furred ceiling of functional areas.

The common networking mode of multisystem indoor distributed system is: information source+conjunction channel platform (electric bridge/multiplefrequency mixer/POI)+(relaying+multiplefrequency mixer)+passive antenna-feedback system.When different system quantity is less, adopts up-downgoing to close road mode and cover, when system quantity is more, as during more than 5, for avoiding inter-system interference, up-downgoing can be adopted to divide cable+POI mode.For GSM, TD-SCDMA, TD-LTE, WLAN four networks one platform system, advise covering whole region by 1 Ji He road or 2 Ji He road modes.

(1) optimal way 1: through two-stage close road, the first via is 2G+TD-LTE, the second tunnel be TD-LTE+TD-SCDMA, WLAN on end feed-in GSM mono-tunnel, as shown in Figure 1.

(2) optimal way 2: close road through one-level, the first via is 2G+TD-LTE+WLAN, second tunnel is TD-LTE+TD-SCDMA, this kind of each system of situation needs to lay separately trunk cable, in building Vertical Shaft for Light-Current headspace can meet cable or device lays, preferred when installing, as shown in Figure 2.

(3) optimal way 3: close road through two-stage, the first via is 2G+TD-SCDMA+TD-LTE, and the second tunnel is TD-LTE, this mode of prioritizing selection is advised in transformation situation, do not change original 2G, TD system, WLAN adopts the mode of feed-in+lay separately AP, as shown in Figure 3.

Information source selects gsm system for adapting to multichannel, and the equipment of takeover diversity function is selected in suggestion.TD-SCDMA and TD-LTE system main equipment types are baseband extension type (BBU+RRU) base station.The wlan system AP present stage equipment of bid is 802.11n equipment.

Dry input power of putting must meet equipment requirement, dry put to export require to conform to actual situation of opening, after avoiding occurring opening, reduce the problem that dry power output of putting reduces uplink interference, the scene cpable of lowering power less to part area coverage designs.

TD-SCDMA and TD-LTE information source: TD-SCDMA indoor distribution selects BBU+RRU as information source, PCCPCH channel power should be used to carry out compartment system power budget, for ensureing common signal channel and each traffic balance of up-downgoing, Design of Indoor Signal Distributed System TD-SCDMA is fixed for 32dBm gets according to PCCPCH channel power (dicode road), the scene cpable of lowering power design less to part area coverage.The transmitting power of TD-LTE single channel 20M bandwidth presses 37dBm(20W equipment, and 4 carrier frequency calculate) design.

WLAN information source: wlan system puts dress type AP by 20dBm(100mw) consider, indoor distribution type AP is by 27dBm(500mw) consider.

Under capacity is adjusted and need be calculated minimum capacity regular situation needed for each standard according to building number of users and mobile subscriber's permeability and 2G, TD-SCDMA, TD-LTE, WLAN business proportion, capacity corresponding to each system configuration is as follows:

The interference that in system, the dry introducing of putting of multiple stage will inevitably cause the up end to make an uproar to base station, therefore in order to improve the performance of base station, single base station dry is put quantity and is exceeded some and need subregion, as follows:

(1), the dry quantity of putting of office building single base station needs subregion more than 6 (5W);

(2), house, community distribution and the base station of villa are with dry quantity of putting to be no more than 10 (10W);

(3), the dry quantity of putting of other building calculates with reference to office building.

Wlan system is under the single user throughput met the demands is not less than the prerequisite of 500kbps, and the supported concurrent user number of single AP is 20, and the most relevance number of users that single AP supports can be determined according to 64.

TD-LTE mainly carries high-speed data service (>500kbps), and possesses the ability of carrying language service.TD-LTE data rate coverage requirement is as follows: in the single community 20MHz networking situation in indoor, require that single community average throughput meets DL40Mbps/UL10M; If actual isolation condition does not allow, according to single community 10MHz, the planning of dual-frequency point inter-frequency networking, can require that single community average throughput meets DL20Mbps/UL5M/10MHz.The method of LTE volume calculation is different from traditional capacity estimation method, affects the many factors of LTE volume calculation, comprises the factors such as environment, multi-antenna technology, interference elimination, dispatching algorithm, equipment performance, therefore can not simply utilize formula to calculate.At present, the cell throughout under industry obtains various wireless scene mainly through the method for system emulation and actual measurement statistics, under network and the various configuration of UE and cell edge throughput:

(1) plot planning will consider indoor specific environment, and the penetration loss that can produce by natural covers such as the floor of building, bodies of wall forms the isolation of minizone, and this is even more important for the system that this quefrency of TD-SCDMA, TD-LTE is not abundant.

(2) (as: same floor is by the market of multiple MPS process, supermarket for spacious or closure is poor indoor environment, elevator and elevator hall in the building of upper and lower subregion, or the open indoor environment such as Tiao Kong hall, stadiums), strictly must control the overlay area between different districts, and by adopting the means such as inter-frequency networking between different districts, ensure that compartment system reaches performance index requirement.

(3) number of cells should balancedly cover and capacity, and comprehensively determines in conjunction with the equipment performance of building structure, different technologies standard, thus avoids later stage capacity increase to do large adjustment to existing network indoor distributed system.

(4), during many technology standard shared distributed system, subregion or sub-clustering concept are introduced in position, Ke He road.Because TD-SCDMA is the standard that indoor requirement generally covers, the compartment system loss that can allow in TD-SCDMA information source, as the standard of subregion loss, is defined between 25 ~ 30dB.WLAN information source can be used as the standard of sub-clustering, is defined in about 12 ~ 15dB without during power amplifier.With subregion and sub-clustering for base unit, build the compartment system topological structure being easy to adjust.

(5) 500mW indoor distribution type WLAN AP, can by support 4 ~ 6 antennas in design, and area coverage 800 ~ 1200 square metres is planned.

(6) put because WLAN is dry than WLANAP costliness, dry performance of putting is difficult to ensure easily to introduce interference, and does not meet country without committee's relevant regulations, and WLANAP end should not access dry putting again.

The planning proposal of indoor distributed system cell handover area follows following principle:

(1) Zone switched should consider require switching time and the setting of the factor such as inter-cell interference level.

(2) the Zone switched planning of indoor distributed system community and outdoor macro base station is in the porch of building.

(3) community of elevator divides: advise elevator and low layer to be divided into same community, and elevator hall uses as far as possible and covers with cell signal with elevator, guarantees that switching in elevator hall between elevator and flat bed occurs.

Leak the signal unduly outside covering chamber controlling indoor covering system, and the outer indoor covering system level of ensuring coverage building 10-15 rice is lower than outdoor 15dBm.For anti-stop signal excessive leakage, the antenna near building door and window place can process as follows:

Less than (1) 5 layer can adopt directional ceiling antenna;

(2) if building periphery has viaduct, overpass, the use floor of directional ceiling antenna can suitably be increased according to the height of bridge;

(3) the adjacent building covered by different base station, if distance is less than or equal to 20 meters, need to increase directional ceiling antenna, Leakage prevention.

Feeder line using priciple: in the subsystem flat bed feeder line of room, length need more use 7/8 feeder line more than 50m; In trunk feeder, length need use 7/8 feeder line more than 1/2 feeder line of 30m.

Information source installation specification, for meeting following multisystem demand, is required to be plurality of information resources and reserves suitable installation site.The integrated level of TD-LTE equipment is higher, and BBU device height is all no more than 4U, and can install in 19 frames of standard.When BBU installs, the space of 1U should be retained up and down for equipment cooling.The ground connection of BBU provides by 19-inch standard cabinet is unified.If adopted and existing base station computer room construction altogether, if there are corresponding 19 frames original base station, and there is the space of 6U that the BBU equipment of TD-LTE just can be installed.If newly-built base station, then need a seat in the plane can meet the installation requirement of BBU equipment.WLAN mainly adopts end to close the mode feed-in information source on road, therefore needs the feed-in position in WLAN information source, as the places such as vertical shaft reserve WLAN information source feed-in space.

Astronomical cycle requires aerial position: the installation site of antenna meets the designing requirement of antenna point position.Antenna is fixed: wall-hung type antenna must be fixedly mounted on wall, ensures that antennas orthogonal is attractive in appearance, and does not destroy indoor integrated environment.Ceiling type antenna can be fixedly mounted on outside furred ceiling or in furred ceiling, ensures that antenna level is attractive in appearance, and does not destroy indoor integrated environment.Isolation distance between portable antenna and other operator's antenna: for preventing the interference between different system, in same building mobile compartment system and other operators distribution system antenna between more than 1 meter should be had to isolate.

Acceptance requirement under resource-constrained condition has call demand for client and reality builds the larger region of difficult point, answers the technology such as active adoption degree of depth covering to make up.When estimating to adopt degree of depth covering scheme still cannot meet acceptance index, should set up session discussing mechanism, the departments concerned discusses solution jointly.Under resource-constrained scene, cell-edge coverage rate index should be not less than other operator's similar system (near frequency band) coverage rates.Client has the place of call demand must meet covering as far as possible, and the client such as high-rise stair, roof, unattended equipment room, the hydroelectric station low place of demand of conversing can be used as non-active overlay area, and non-active overlay area will control within 5%.

In special screne situation:

(1) outside light spike antenna carries out feed-in according to actual WLAN mould survey effect;

(2) in Vertical Shaft for Light-Current, elevator hoistways, installation whip antenna and directed plate antenna temporarily first do not consider that WLAN covers.

The ubiquitous problem of existing four net fusion indoor distribution radio signal coverage system is as follows at present:

wireless aspect: the major issue that 3G and TD-LTE faces is the problem that the degree of depth covers, and because 3G/4G system works is at ultrashort wave frequency band, radio wave diffraction ability, penetration loss is comparatively large, therefore certainly exists many deficiencies when profound level covers.Compare with current 2G network, 3G/4G network has more weak signal areas and occurs, particularly at interior of building, there is the shortcoming of many, the easy broken strings in blind area, network performance instability especially.

According to ASSOCIATE STATISTICS both domestic and external, the voice service in 3G epoch 70% and the data service of 90% occur in indoor.But the 3G practice of China does not but follow external rule.We add up the contained fan be exclusively used in covering chamber and traffic, no matter absorb or carrying user from flow, RRU all fails to play to answer role.

One group of data has proved above-mentioned conclusion: the ratio that indoor contained fan accounts for the whole network is 1.8%, and the ability absorbing flow only has 1.2%, and the ability of carrying user only has 1.5%.Therefore, the absorbability of RRU will be weaker than the absorbability of common grand sector.

At present, reason has three, the first, the less pertinence that indoor distributed system is built, and the indoor building of part are by macro station quorum sensing inhibitor; The second, indoor distribution build after, outdoor macro station fail Synchronous fluorimetry adjustment, cause indoor and outdoor signal to go wrong; 3rd, the aerial position of high-rise building has to be placed on corridor because of a variety of causes, and the user that result also in office employs outdoor signal.

The position that the environment such as the RRU of major part indoor distributed system is placed between cabling, light current well, piping shaft, stairs port are poor, because RRU port transmitting power, two-way length of cable and passive device loss there are differences, certain unbalanced power is there is between two passages of binary channels room subsystem by causing, have influence on the accuracy that terminal signaling is estimated, thus reduce MIMO performance.

power supply aspect: because signal between BBU to RRU only uses an optical fiber just passable, but the power between BBU and RRU how to solve be a large problem of 3G indoor distributed system.The operator that has now adopts the scheme of DC boosting confession far away, and some operators take inverter scheme, all represent the exploration of operator to powering mode under the BBU+RRU framework of 3G communication.But far away from there is lightning protection, antitheft, pressure drop, loss, safety, high in cost of production shortcoming, quantity few in actual applications.

In the construction in early stage, owing to ensureing that consideration is not enough to the standby electricity of the battery of 3G indoor distributed system, the initial stage of building a station adopts electric main directly to introduce in a large number, does not configure back-up source and batteries.Not power guarantee after interchange has a power failure, cause indoor distributed system often because clothes are moved back in power-off after commercial power interruption, have a strong impact on running quality and the reliability of network.

Indoor distribution scene, can be divided into Alternating Current Power Supply and direct current supply according to the power supply system of equipment, can be divided into centrally connected power supply and decentralized power supply according to supply power mode.Ac power supply method, has direct Alternating Current Power Supply not have the standby electricity of battery at present and adopts UPS to power two kinds of situations.The first situation is more in early days, and along with the attention ensured of powering to 3G indoor distribution, it is fewer and feweri that direct electric main is powered.Because the battery management function of UPS is more weak, UPS scheme is generally not too approved by operator.Just as outdoor base station recent years adopts outdoor switch power supply to replace outdoor UPS in a large number, under the application scenarios of 3G indoor distribution, the situation adopting UPS to power is little.

(1) concentration supply power solution

Concentration supply power solution adopts a set of power-supply system, both powers to BBU, and the mode simultaneously by zooming out is powered to far-end RRU.The advantage of scheme is: power supply is concentrated, be convenient to maintenance, save equipment investment; Shortcoming is: zooming out distance has certain restriction, line loss larger, general recommend zoom out distance within 100 meters.

(2) decentralized power-supply solution

Decentralized power-supply solution, be adopt how cover power-supply system is powered to BBU and RRU respectively nearby, its advantage is: power nearby, line loss is little, for electrodispersion, supply risk little; Shortcoming is: power-supply system is many, investment is large, equipment dispersion.

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.

The present invention is weigh the most basic index of mobile communications network according to the quality covered, and design a set of four completely newly active+passive+active nets and merge indoor distributed system, the degree of depth that namely this system can meet multiple indoor telephone traffic covers.Namely the demand of traffic City Regions can be met; Also can meet the regional demand that the telephone traffics such as medium telephone traffic area and underground parking such as commercial office complex are not high simultaneously.

Brand-new four nets merge indoor distributed systems wireless domain and field of power supplies are merged mutually realize GSM, TD-SCDMA, WLAN and TD-LTE four net and deposit and four net between cooperative development, thus fundamentally solution mobile communication three basic principles.

1. wireless aspect

The problem of the position that the environment such as the RRU for current most of indoor distributed system is placed between cabling, light current well, piping shaft, stairs port are poor.

So technological core of the present invention is exactly the installation question first solving RRU.The present invention is displaced to covering area range before can making all RRU directly by the equipment and system that four net fusion indoor distribution spider web mode power and wireless signal cover and installs.So just can reduce the quantity of the passive device such as antenna, mixer and antenna feeder cable length, improve indoor distributed system constructive ability targetedly, and RRU be played answer role.Comprehensive raising indoor distribution absorbs the ability of flow, carrying user.Thus because RRU port transmitting power, two-way length of cable and passive device loss there are differences after fundamentally solving four net fusions, certain unbalanced power is there is between two passages of binary channels room subsystem by causing, have influence on the accuracy that terminal signaling is estimated, thus reduce the problem of MIMO performance, and the problem that 3G and the TD-LTE degree of depth covers.

After raising indoor distributed system targetedly constructive ability, technological core of the present invention is exactly the silk screen that reference the Nature spider is made into, if there is insect to cast net, the principle that vibration through signal silk just can be heard the news and be taken food, devises four nets and merges indoor distributed system part zero traffic regions and carry out timesharing, segmentation, wirelessly reduce discharging operational mode with the environment protecting and power-saving of power-supply device dormancy.Its operation principle is summarized as follows:

Distributed type minisize alternating current-direct current spider web 48v main switch power supply, 2G/3G/4G-BBU/WLAN-ONU representative is the Nature spider, the cable of transmission power supply, transmission light photoelectric compound cable, the silk screen dividing active 7/8,1/2 antenna feeder common networking to form the Nature spider to be made into room.Distributed type minisize alternating current-direct current spider web 48v on spider web and Switching Power Supply, spider web is for the balanced sending module of Electrodynamic balance, spider web wireless network covers dynamic chain detecting module, 2G/4G/3G-RRU, spider web is for Electrodynamic balance balanced reception module, POE-WLAN, 2G/4G multifrequency active power filtering isolation mixer, 2G/WLAN multifrequency active power filtering isolation mixer, 3G/4G multifrequency active power filtering isolation mixer, 2G/4G active signal amplifying coupler, power splitter forms the vibration monitoring point of spider web signal silk.

When four nets merge equipment and system zones of different spider web monitoring point that indoor distribution spider web mode power and wireless signal cover test there is timesharing, segmentation zero traffic time.Spider (i.e. distributed type minisize alternating current-direct current spider web 48v Switching Power Supply, 2G/3G/4G-BBU/WLAN-ONU) changes according to silk screen electric current and voltage and vibration monitoring point up and down power, telephone traffic active equipment indoor distribution spider web system green environmental protection dormancy energy-saving and emission-reduction mode operations such as carrying out control realization power supply wireless.

2. power supply aspect

Field of power supplies utilizes the antenna feeder of existing network 2G, 3G system and FTTH optical cable to set up relevant wireless network and covers spider web supplying channels.In the area of the weak covering in indoor while powering to four net nucleus equipments, power also to transmitting terminal and receiving terminal different capacity size wireless network signal amplifying device and active monopolar/bipolar antenna.

The brand-new C-RAN of the one that the present invention takes centrally connected power supply and decentralized power supply to combine in practice distributed spider web indoor power supply scheme is the further innovation at present to existing power supply technique.The framework of the multistage different power voltage grade of the Radio Access Network of " green energy conservation (Clean) " of feature that the present invention has " centralization (Centralize), Collaborative Collaborative), cloud computing (Cloud) ".Such as, for the indoor distribution of a tens layers high building, same set of distributed type minisize alternating current-direct current spider web low-voltage 36-48v main switch power supply is used with BBU near the RRU of BBU, RRU away from BBU can concentrate 1-2 to overlap distributed type minisize alternating current-direct current spider web high voltage 50-60v on wall-hanging spider web from Switching Power Supply at the middle part in building, zoom out nearby and power.Principal and subordinate's power supply is carried out connecting by the spider web on spider web for the balanced sending/receiving module of Electrodynamic balance and carries out voltage control output, and this mode compensate for the deficiency of centrally connected power supply and decentralized power supply, solves and draws remote problem and reduce cost of investment.

Four net collaborative distributed spider web base station power supply systems need to adopt novel feed system, dynamic environment monitoring system etc.Therefore, based on distributed spider web base station power supply system under four net integrated environments, to meet new forms of energy base station requests and existing network power conservation requirement, following content is mainly comprised:

1) cable+composite cable under C-RAN distributed base station spider web power supply system+antenna feeder hybrid power supply Path Setup;

2) power distribution equipment is divided based on distributed group net mode spider web distributed intelligence;

3) spider web system controller sampling module, spider web switching value module realize;

4) design and implimentation of spider web centrally connected power supply power supply real-time monitoring system.

Technological core of the present invention is exactly use for reference the silk screen that the Nature spider is made into, if there is insect to cast net, the principle design that the vibration through signal silk just can be heard the news and be taken food four nets merge indoor distribution electric power systems.Spider web level Four Energy transmission control system, namely according to load timesharing, the segmentation change of 2G, 3G, 4G, WLAN, RRU on every one-level silk screen, match with spider distributed type minisize alternating current-direct current spider web 48v master slave switch power supply for Electrodynamic balance balanced sending/receiving module A, B, C, D, E, F through the spider web on signal silk, form a set of brand-new dynamic divergence form power spider web, dynamic seal closed form of spider web, dynamic convergence type of powering and to power spider web.Silk screen at different levels is different according to the load-carrying importance of institute, adopts differentiation to power output Support Mode, thus reaches the realization that the best power supply plan of whole compartment system configures automatically.

The selection of indoor distribution spider web system coverage mode scheme of the present invention depends primarily on the feature of building self, such as: the ambient conditions in the scale of building, building, the purposes etc. of building.Each building all has features different separately, so the indoor construction scheme of each building is made to measure depending on concrete condition.

The selection of 3G indoor distributed system scheme depends primarily on the feature of building self, such as: the ambient conditions in the scale of building, building, the purposes etc. of building.Each building all has features different separately, so the indoor construction scheme of each building is made to measure depending on concrete condition.

From narrow sense, in-door covering problem is only the improvement to in-door covering blind area, solves the problem that phone is not shown.From broadly, in-door covering problem comprises the improvement to indoor mobile communication speech quality, network quality, power system capacity, solves the problem of quality of making a phone call.Except to such as basement, the communication blind district such as, two layer provides outside covering, the high-level partial of simultaneously also tackling building because of receive to cause from multidirectional mixed and disorderly unstable signal call drop, interrupted, switch the aspect such as unsuccessful and improve.For commercial affairs, the commerce trading center of high traffic, also should solve indoor telephone traffic and absorb and congestion problems.Therefore, the improvement of in-door covering signal covers for expansion, improves covering quality, improves call completing rate, reduces weak signal call drop, reduces co-channel interference and be also very helpful.Meanwhile, in-door covering, as a kind of dilatation means, is sharing outdoor base station traffic, increases network capacity, makes indoor telephone traffic in indoor absorption, reduces co-channel interference and also cuts much ice.In addition, good in-door covering, for raising network operation image, for user provides better more perfect communication service whenever and wherever possible, improves enterprise competitiveness and has a very big significance.
