背景技术Background technique
室内覆盖是整体无线网络的重要组成部分,建设室内分布系统有利于吸收话务量,提升用户感知,增强用户粘性。在四网融合的业务发展背景下,GSM(以下可以简称2G)、TD-SCDMA(以下可以简称TD或3G)、TD-LTE(以下可以简称4G)、WLAN具备不同的覆盖能力和业务场景,将长期共存。多技术室内分布系统的设计需要统筹考虑,如何使分布系统资源得到充分、合理地利用,避免重复建设、重复施工以及系统间相互影响成为需要认真考虑的问题。Indoor coverage is an important part of the overall wireless network. Building an indoor distribution system is conducive to absorbing traffic, improving user perception, and enhancing user stickiness. Under the background of business development of four-network integration, GSM (hereinafter referred to as 2G), TD-SCDMA (hereinafter referred to as TD or 3G), TD-LTE (hereinafter referred to as 4G), and WLAN have different coverage capabilities and business scenarios. will coexist for a long time. The design of multi-technology indoor distribution system needs to be considered as a whole. How to make full and reasonable use of distribution system resources and avoid repeated construction, repeated construction and mutual influence between systems has become a problem that needs to be carefully considered.
(1)室内分布系统的建设要统筹考虑GSM、TD-SCDMA、TD-LTE、WLAN四网融合的目标,提前考虑WLAN大规模部署以及LTE引入等因素对分布结构的影响,避免后期频繁改动。(1) The construction of the indoor distribution system should take into account the goal of four-network integration of GSM, TD-SCDMA, TD-LTE, and WLAN, and consider the impact of large-scale deployment of WLAN and the introduction of LTE on the distribution structure in advance to avoid frequent changes in the later stage.
(2)应综合考虑网络容量、系统干扰、资源情况、建设难度、投资成本等各种因素选择最佳建设模式。(2) Various factors such as network capacity, system interference, resource conditions, construction difficulty, and investment costs should be considered comprehensively to select the best construction mode.
(3)应遵循现有的各技术制式下分布系统的设计原则,并满足各自系统的设计指标。(3) The existing design principles of distributed systems under various technical standards should be followed, and the design indicators of their respective systems should be met.
(4)应精心设计分布系统拓扑结构,充分考虑新制式的影响,便于新系统的引入:以TD-SCDMA制式的技术条件来确定分区,以WLAN制式的技术条件来确定分簇,使分布系统局部的调整尽量在分簇或分区的小范围内进行,避免引入新技术时对整个系统的拓扑结构进行大调整。(4) The topological structure of the distributed system should be carefully designed, fully considering the influence of the new standard, and facilitating the introduction of the new system: the technical conditions of the TD-SCDMA standard are used to determine the partition, and the technical conditions of the WLAN standard are used to determine the clustering, so that the distributed system Local adjustments should be made within a small range of clustering or partitioning as much as possible, to avoid major adjustments to the topology of the entire system when new technologies are introduced.
(5)建设室内分布系统的物业点应能保证优质的室内覆盖,同时要控制好室内信号,避免对室外构成强干扰。(5) The property site where the indoor distribution system is built should be able to ensure high-quality indoor coverage, and at the same time control the indoor signal to avoid strong interference to the outdoors.
(6)分布系统建设应考虑多系统间的干扰,尤其关注室内LTE与WLAN的天线隔离,以及多系统合路器的干扰抑制指标。(6) The construction of the distributed system should consider the interference between multiple systems, especially the antenna isolation between indoor LTE and WLAN, and the interference suppression index of the multi-system combiner.
(7)室内分布系统应按照WLAN的频段进行模测和布放天线点,并采用“多天线、小功率”的原则进行建设,电磁辐射必须满足国家和通信行业相关标准。(7) The indoor distribution system should be modeled and placed according to the frequency band of the WLAN, and the principle of "multi-antenna, low power" should be adopted for construction. The electromagnetic radiation must meet the relevant standards of the country and the communication industry.
(8)对于前期只进行GSM建设的站点,在引入WLAN系统时,首先对原GSM系统达不到WLAN覆盖效果的区域进行补点,再馈入WLAN信号,然后对WLAN容量需求高的重点区域单独布放AP进行组网设计。(8) For sites that only have GSM construction in the early stage, when introducing the WLAN system, first make up points for areas where the original GSM system cannot reach the coverage effect of WLAN, and then feed in WLAN signals, and then focus on key areas with high demand for WLAN capacity Deploy APs independently for networking design.
(9)对于前期出过GSM+TD-SCDMA方案的站点,在馈入WLAN系统时,首先对原GSM+TD-SCDMA系统馈入WLAN信号,然后对WLAN覆盖弱区域或容量需求高的重点区域单独布放AP进行组网设计。(9) For sites that have previously developed a GSM+TD-SCDMA solution, when feeding into the WLAN system, first feed the WLAN signal into the original GSM+TD-SCDMA system, and then feed into the key areas with weak WLAN coverage or high capacity requirements Deploy APs independently for networking design.
需要说明的是,四网融合设计方案对于WLAN系统而言,原则上要以馈入方式为主,重点区域(会议室、多功能厅等)单独布放的原则来考虑,交换机主要安装于机房或弱电竖井内,AP馈入时主要安装于机房、弱电竖井内,AP单独布放时主要布放在功能区的吊顶内。It should be noted that for the WLAN system, the four-network integration design scheme should be based on the principle of feed-in, and the key areas (meeting rooms, multi-function halls, etc.) should be separately deployed. The switch is mainly installed in the computer room Or in weak current shafts, AP feed-in is mainly installed in the equipment room and weak current shafts, and APs are deployed separately in the ceiling of the functional area.
多系统室内分布系统常见组网方式为:信源+合路平台(电桥/多频合路器/POI)+(中继+多频合路器)+无源天馈系统。异系统数量较少时,采用上下行合路方式覆盖,当系统数量较多,如超过5个时,为避免系统间干扰,可采用上下行分缆+POI方式。对于GSM、TD-SCDMA、TD-LTE、WLAN四网合一系统,建议通过1级合路或2级合路方式覆盖整个区域。The common networking mode of the multi-system indoor distribution system is: signal source + combining platform (bridge/multi-frequency combiner/POI) + (relay + multi-frequency combiner) + passive antenna system. When the number of different systems is small, the uplink and downlink combination method is used for coverage. When the number of systems is large, such as more than 5, in order to avoid inter-system interference, the uplink and downlink splitting + POI method can be used. For the GSM, TD-SCDMA, TD-LTE, and WLAN four-network integration system, it is recommended to cover the entire area through 1-level combination or 2-level combination.
(1)优选方式1:经过两级合路,第一路为2G+TD-LTE,第二路为TD-LTE+TD-SCDMA,WLAN在末端馈入GSM一路,如图1所示。(1) Preferred method 1: After two-stage combination, the first path is 2G+TD-LTE, the second path is TD-LTE+TD-SCDMA, and WLAN feeds into GSM path at the end, as shown in Figure 1.
(2)优选方式2:经过一级合路,第一路为2G+TD-LTE+WLAN,第二路为TD-LTE+TD-SCDMA,此种情况各系统需要单独布放主干线缆,在楼宇内弱电竖井预留空间能满足线缆或器件布放、安装的情况下优选,如图2所示。(2) Optimum method 2: After a first-level combined circuit, the first channel is 2G+TD-LTE+WLAN, and the second channel is TD-LTE+TD-SCDMA. In this case, each system needs to lay out the backbone cables separately. It is preferred when the reserved space of the weak current shaft in the building can meet the layout and installation of cables or devices, as shown in Figure 2.
(3)优选方式3:经过两级合路,第一路为2G+TD-SCDMA+TD-LTE,第二路为TD-LTE,改造情况下建议优先选择此方式,不改动原有的2G、TD系统,WLAN采用馈入+单独布放AP的方式,如图3所示。(3) Optimum method 3: After two-level combination, the first path is 2G+TD-SCDMA+TD-LTE, and the second path is TD-LTE. In the case of transformation, it is recommended to choose this method first, without changing the original 2G , TD system, the WLAN adopts the way of feed-in + separate AP deployment, as shown in Figure 3.
信源选择GSM系统为适应多通道,建议选用有接收分集功能的设备。TD-SCDMA和TD-LTE系统主要设备类型为基带拉远型(BBU+RRU)基站。WLAN系统AP现阶段招标设备均为802.11n设备。Source selection GSM system In order to adapt to multi-channel, it is recommended to choose equipment with receive diversity function. The main equipment type of TD-SCDMA and TD-LTE system is the remote baseband (BBU+RRU) base station. The current bidding equipment for the WLAN system AP is 802.11n equipment.
干放的输入功率必须满足设备要求,干放输出要求与实际开通情况相符,避免出现开通后,降低干放的输出功率减少上行干扰的问题,对部分覆盖面积较小的场景可降低功率设计。The input power of the dry amplifier must meet the requirements of the equipment, and the output requirements of the dry amplifier must be consistent with the actual opening conditions. After opening, the problem of reducing the output power of the dry amplifier to reduce uplink interference can be avoided. For some scenarios with small coverage areas, the power design can be reduced.
TD-SCDMA及TD-LTE信源:TD-SCDMA室内分布选用BBU+RRU作为信源,应使用PCCPCH信道功率进行分布系统功率预算,为保证公共信道和上下行各业务平衡,室内分布系统设计TD-SCDMA按照PCCPCH信道功率(双码道)为32dBm取定,对部分覆盖面积较小的场景可降低功率设计。TD-LTE单通道20M带宽的发射功率按37dBm(20W设备,4载频计算)设计。TD-SCDMA and TD-LTE signal source: TD-SCDMA indoor distribution uses BBU+RRU as the signal source, and PCCPCH channel power should be used to distribute the system power budget. In order to ensure the balance of public channels and uplink and downlink services, the indoor distribution system design TD -SCDMA is determined according to the PCCPCH channel power (dual-code channel) as 32dBm, and the power design can be reduced for some scenarios with small coverage areas. The transmit power of TD-LTE single channel 20M bandwidth is designed according to 37dBm (20W equipment, 4 carrier frequency calculation).
WLAN信源:WLAN系统放装型AP按20dBm(100mw)进行考虑,室内分布型AP按27dBm(500mw)进行考虑。WLAN signal source: 20dBm (100mw) for WLAN installed APs, and 27dBm (500mw) for indoor distributed APs.
容量核算需根据楼宇用户数及移动用户渗透率及2G、TD-SCDMA、TD-LTE、WLAN业务比例测算各制式所需最小容量常规情况下,各系统配置对应的容量如下:Capacity calculation needs to calculate the minimum capacity required by each system based on the number of building users, mobile user penetration rate and 2G, TD-SCDMA, TD-LTE, WLAN business ratio. Under normal circumstances, the corresponding capacity of each system configuration is as follows:
系统中多台干放的引入必然会对基站造成上行底噪的干扰,因此为了提高基站的性能,单个基站的干放数量超过一定数量需要分区,如下:The introduction of multiple dry amplifiers in the system will inevitably cause interference to the uplink noise floor of the base station. Therefore, in order to improve the performance of the base station, the number of dry amplifiers in a single base station exceeds a certain number and needs to be partitioned, as follows:
(1)、写字楼单个基站的干放数量超过6台(5W)需要分区;(1) The number of dry discharge of a single base station in an office building exceeds 6 (5W) and needs to be partitioned;
(2)、住宅、小区分布和别墅的基站所带干放数量不超过10台(10W);(2), the number of dry discharges carried by the base stations of residences, community distribution and villas shall not exceed 10 (10W);
(3)、其它楼宇的干放数量参考写字楼计算。(3) The dry discharge quantity of other buildings is calculated with reference to the office buildings.
WLAN系统在满足要求的单用户吞吐量不低于500kbps的前提下,单AP可支持的并发用户数为20个,单AP支持的最大关联用户数可按照64个确定。Under the premise that the WLAN system meets the required single-user throughput not less than 500kbps, the number of concurrent users that a single AP can support is 20, and the maximum number of associated users supported by a single AP can be determined as 64.
TD-LTE主要承载高速数据业务(>500kbps),并具备承载语言业务的能力。TD-LTE数据速率覆盖要求如下:在室内单小区20MHz组网情况下,要求单小区平均吞吐量满足DL40Mbps/UL10M;若实际隔离条件不允许,可以按照单小区10MHz、双频点异频组网规划,要求单小区平均吞吐量满足DL20Mbps/UL5M/10MHz。LTE容量估算的方法不同于传统的容量估算方法,影响LTE容量估算的因素较多,包括环境、多天线技术、干扰消除、调度算法、设备性能等因素,因此不能简单的利用公式来进行计算。目前,业界主要通过系统仿真和实测统计数据的方法获得各种无线场景下、网络和UE各种配置下的小区吞吐量和小区边缘吞吐量:TD-LTE mainly carries high-speed data services (>500kbps), and has the ability to carry language services. TD-LTE data rate coverage requirements are as follows: In the case of indoor single-cell 20MHz networking, the average throughput of a single cell is required to meet DL40Mbps/UL10M; if the actual isolation conditions do not allow, it can be based on single-cell 10MHz, dual-frequency point and different frequency networking According to the plan, the average throughput of a single cell is required to meet DL20Mbps/UL5M/10MHz. The LTE capacity estimation method is different from the traditional capacity estimation method. There are many factors affecting the LTE capacity estimation, including environment, multi-antenna technology, interference cancellation, scheduling algorithm, equipment performance and other factors. Therefore, formulas cannot be used for calculation. At present, the industry mainly obtains cell throughput and cell edge throughput under various wireless scenarios, network and UE configurations through system simulation and measured statistical data:
(1)小区规划要考虑室内具体环境,可借助建筑物的楼板、墙体等自然屏障产生的穿透损耗形成小区间的隔离,这对于TD-SCDMA、TD-LTE这类频率并不充裕的系统尤其重要。(1) The specific indoor environment should be considered in the planning of the residential area. The penetration loss generated by the natural barriers such as the floor and the wall of the building can be used to form the isolation between the residential areas, which is not sufficient for frequencies such as TD-SCDMA and TD-LTE. System is especially important.
(2)空旷或封闭性较差的室内环境(如:同一楼层由多个小区覆盖的商场、超市,上下分区的楼宇中电梯及电梯厅,或挑空大堂、体育场馆等开放性室内环境),必须严格控制不同小区之间的覆盖区域,并通过不同小区之间采用异频组网等手段,保证分布系统达到性能指标要求。(2) Empty or poorly enclosed indoor environments (such as shopping malls and supermarkets covered by multiple communities on the same floor, elevators and elevator halls in buildings with upper and lower partitions, or open indoor environments such as empty lobbies and stadiums) , must strictly control the coverage area between different cells, and adopt different frequency networking and other means between different cells to ensure that the distribution system meets the performance index requirements.
(3)小区数量应均衡覆盖和容量,并结合楼宇结构、不同技术制式的设备性能来综合确定,从而避免后期容量增加对现网室内分布系统做大的调整。(3) The number of cells should balance coverage and capacity, and be comprehensively determined in combination with building structures and equipment performance of different technical standards, so as to avoid large adjustments to the existing network indoor distribution system due to later capacity increases.
(4)多技术制式共用分布系统时,可在合路位置引入分区或分簇概念。由于TD-SCDMA是室内要求普遍覆盖的制式,可以在TD-SCDMA信源允许的分布系统损耗作为分区损耗的标准,定义在25~30dB之间。WLAN信源可作为分簇的标准,无功放时定义在12~15dB左右。以分区及分簇为基本单位,构建易于调整的分布系统拓扑结构。(4) When multiple technical standards share the distribution system, the concept of partition or clustering can be introduced at the joint position. Since TD-SCDMA is a standard that requires universal coverage indoors, the distribution system loss allowed by the TD-SCDMA source can be used as the standard for partition loss, which is defined between 25 and 30dB. The WLAN source can be used as a clustering standard, and it is defined as about 12-15dB when there is no power amplifier. Taking partition and clustering as the basic unit, construct an easily adjustable distributed system topology.
(5)500mW室内分布型WLAN AP,设计中可按支持4~6个天线,覆盖面积800~1200平方米进行规划。(5) The 500mW indoor distributed WLAN AP can be designed to support 4 to 6 antennas and cover an area of 800 to 1200 square meters.
(6)由于WLAN干放比WLANAP昂贵,干放性能难以保证易引入干扰,且不符合国家无委相关规定,WLANAP末端不应再接入干放。(6) Since the WLAN dry amplifier is more expensive than the WLANAP, the performance of the dry amplifier is difficult to guarantee and it is easy to introduce interference, and it does not meet the relevant regulations of the State Council, so the WLANAP end should not be connected to the dry amplifier.
室内分布系统小区切换区域的规划建议遵循以下原则:The planning of the cell switching area of the indoor distribution system is recommended to follow the following principles:
(1)切换区域应综合考虑切换时间要求及小区间干扰水平等因素设定。(1) The handover area should be set with comprehensive consideration of factors such as handover time requirements and inter-cell interference levels.
(2)室内分布系统小区与室外宏基站的切换区域规划在建筑物的入口处。(2) The switching area between the indoor distribution system cell and the outdoor macro base station is planned at the entrance of the building.
(3)电梯的小区划分:建议将电梯与低层划分为同一小区,电梯厅尽量使用与电梯同小区信号覆盖,确保电梯与平层之间的切换在电梯厅内发生。(3) Elevator community division: It is recommended to divide the elevator and the lower floors into the same community, and the elevator hall should try to use the signal coverage of the same community as the elevator to ensure that the switch between the elevator and the leveling floor occurs in the elevator hall.
外泄控制室内覆盖系统的信号不过度覆盖室外,保证覆盖建筑物10-15米外室内覆盖系统电平低于室外15dBm。为防止信号过度泄漏,靠近楼宇门窗处的天线可按如下方法处理:Leakage control The signal of the indoor coverage system does not cover the outdoors too much, and the level of the indoor coverage system covering 10-15 meters away from the building is guaranteed to be 15dBm lower than that of the outdoors. In order to prevent excessive signal leakage, the antenna near the door and window of the building can be handled as follows:
(1)5层以下可以采用定向吸顶天线;(1) Directional ceiling antennas can be used below 5 floors;
(2)如果楼宇周边有立交桥、过街天桥,可以根据桥的高度适当增加定向吸顶天线的使用楼层;(2) If there are overpasses and overpasses around the building, the use floor of the directional ceiling antenna can be appropriately increased according to the height of the bridge;
(3)由不同基站覆盖的相邻楼宇,如果距离小于等于20米,需要增加定向吸顶天线,防止泄漏。(3) For adjacent buildings covered by different base stations, if the distance is less than or equal to 20 meters, directional ceiling antennas need to be added to prevent leakage.
馈线使用原则:室分系统平层馈线中长度超过50m的需更使用7/8馈线;主干馈线中长度超过30m的1/2馈线需使用7/8馈线。Principles of feeder use: 7/8 feeder should be used for leveling feeder of room distribution system longer than 50m; 1/2 feeder of main feeder longer than 30m should use 7/8 feeder.
信源安装规范为满足未来多系统需求,需为多种信源预留适当的安装位置。TD-LTE设备的集成度较高,BBU设备高度均不超过4U,并且都可以在标准的19机架上安装。BBU安装时,上下应该保留1U的空间用于设备散热。BBU的接地由19英寸标准机柜统一提供即可。如果采用与现有基站共机房建设,原有基站如果有相应的19机架,并且有6U的空间就可以安装TD-LTE的BBU设备。如果是新建基站,则需要一个机位即可满足BBU设备的安装要求。WLAN主要采用末端合路的方式馈入信源,因此需要在WLAN信源的馈入位置,如竖井等处预留WLAN信源馈入空间。Information Source Installation Specifications In order to meet future multi-system requirements, it is necessary to reserve appropriate installation locations for various information sources. TD-LTE equipment has a high degree of integration, and the height of BBU equipment does not exceed 4U, and all of them can be installed on a standard 19 rack. When installing the BBU, a 1U space should be reserved above and below for heat dissipation of the device. The grounding of the BBU can be provided uniformly by a 19-inch standard cabinet. If the same computer room is used with the existing base station, if the original base station has a corresponding 19 racks and a 6U space, TD-LTE BBU equipment can be installed. If it is a new base station, one camera position is needed to meet the installation requirements of BBU equipment. WLAN mainly uses end-combining to feed signal sources, so it is necessary to reserve WLAN signal source feed-in space at the feed-in position of WLAN signal sources, such as shafts.
天线安装要求天线位置:天线的安装位置符合天线点位的设计要求。天线固定:挂墙式天线必须牢固地安装在墙上,保证天线垂直美观,并且不破坏室内整体环境。吸顶式天线可以固定安装在天花吊顶外或天花吊顶内,保证天线水平美观,并且不破坏室内整体环境。移动天线与其它运营商天线之间的隔离距离:为防止不同系统之间的干扰,同一楼宇内移动分布系统与其它运营商分布系统的天线之间应有1米以上隔离。Antenna installation requirements Antenna position: The installation position of the antenna meets the design requirements of the antenna point. Antenna fixation: The wall-mounted antenna must be firmly installed on the wall to ensure that the antenna is vertical and beautiful without damaging the overall indoor environment. The ceiling-mounted antenna can be fixed outside or inside the suspended ceiling to ensure that the antenna is horizontal and beautiful without damaging the overall indoor environment. Isolation distance between mobile antennas and antennas of other operators: In order to prevent interference between different systems, there should be more than 1 meter isolation between the antennas of the mobile distribution system and the distribution systems of other operators in the same building.
资源受限条件下的验收要求对于客户有通话需求而实际建设难点较大的区域,应积极采用深度覆盖等技术来弥补。预计采用深度覆盖方案仍无法满足验收指标时,应建立会议讨论机制,各有关部门共同讨论解决。在资源受限场景下,边缘场强覆盖率指标应不低于其他运营商类似系统(相近频段)覆盖率。客户有通话需求的地方必须尽量满足覆盖,高层楼梯、楼顶、无人值守机房、水电站等客户通话需求低的地方可作为非主动覆盖区域,非主动覆盖区域要控制在5%以内。Acceptance requirements under resource-constrained conditions For areas where customers have call needs but actual construction difficulties are relatively large, technologies such as deep coverage should be actively used to make up for it. When it is expected that the acceptance index cannot be met by adopting the deep coverage scheme, a meeting discussion mechanism shall be established, and all relevant departments shall jointly discuss and solve the problem. In resource-constrained scenarios, the edge field strength coverage index should not be lower than the coverage of similar systems (similar frequency bands) of other operators. Places where customers have call needs must meet the coverage as much as possible. Places with low call needs such as high-rise stairs, building roofs, unattended computer rooms, and hydropower stations can be used as inactive coverage areas, and the inactive coverage areas should be controlled within 5%.
特殊场景情况下:In special scenarios:
(1)室外灯杆天线根据实际WLAN模测效果进行馈入;(1) The outdoor light pole antenna is fed in according to the actual WLAN modeling results;
(2)弱电竖井、电梯井道内安装鞭状天线和定向板状天线暂时先不考虑WLAN覆盖。(2) The installation of whip antennas and directional plate antennas in weak current shafts and elevator shafts does not consider WLAN coverage for the time being.
目前现有四网融合室内分布无线信号覆盖系统普遍存在的问题如下:At present, the common problems in the existing four-network fusion indoor distributed wireless signal coverage system are as follows:
无线方面:3G与TD-LTE面临的一个重要问题是深度覆盖的问题,由于3G/4G系统工作在超短波频段,电波绕射能力差,穿透损耗较大,因此在深层次覆盖时必然存在诸多不足。和目前的2G网络相比,3G/4G网络会有更多弱信号区出现,特别是在建筑物内部,更是存在着盲区多、易断线、网络表现不稳定的缺点。Wireless aspects : An important problem faced by 3G and TD-LTE is the problem of deep coverage. Since the 3G/4G system works in the ultra-short wave frequency band, the radio wave diffraction ability is poor, and the penetration loss is large, so there must be many problems in deep coverage. insufficient. Compared with the current 2G network, there will be more weak signal areas in the 3G/4G network, especially in the interior of the building, which has the disadvantages of many blind spots, easy disconnection, and unstable network performance.
根据国内外的相关统计,3G时代70%的话音业务和90%的数据业务发生在室内。但是,中国的3G实践却并没有遵循国外的规律。我们对专用于覆盖室内的载扇和话务进行了统计,不论从流量吸收还是承载用户看,RRU均未能起到应起的作用。According to relevant statistics at home and abroad, 70% of voice services and 90% of data services in the 3G era take place indoors. However, China's 3G practice does not follow the laws of foreign countries. We made statistics on the bearing fans and traffic dedicated to covering the indoor. No matter from the perspective of traffic absorption or bearing users, the RRU failed to play its due role.
一组数据佐证了上述结论:室内载扇占全网的比例为1.8%,吸收流量的能力只有1.2%,承载用户的能力只有1.5%。因此,RRU的吸收能力要弱于普通宏扇区的吸收能力。A set of data supports the above conclusion: indoor fans account for 1.8% of the entire network, only 1.2% of the traffic can be absorbed, and only 1.5% of the users can be carried. Therefore, the absorbing capacity of the RRU is weaker than that of common macro sectors.
目前来看,原因有三,第一,室内分布系统建设的针对性不够,部分室内楼宇已被宏站信号覆盖;第二,室内分布建设后,室外宏站未能同步优化调整,导致室内外信号出现问题;第三,高层楼宇的天线位置因各种原因不得不放置在走廊,也导致了办公室内的用户使用了室外信号。At present, there are three reasons. First, the construction of the indoor distribution system is not targeted enough, and some indoor buildings have been covered by macro station signals. Second, after the construction of the indoor distribution system, the outdoor macro stations have not been optimized and adjusted synchronously, resulting in indoor and outdoor signals. There are problems; thirdly, the antennas of high-rise buildings have to be placed in the corridors for various reasons, which also causes users in the office to use outdoor signals.
大部分室内分布系统的RRU都放置在走线间、弱电井、管道井、楼梯口等环境较差的位置,由于RRU端口发射功率、两路线缆长度和无源器件损耗存在差异,将导致双通道室分系统的两通道之间存在一定的功率不平衡,影响到终端信号估计的准确度,从而降低MIMO性能。Most of the RRUs of the indoor distribution system are placed in places with poor environments such as wiring rooms, weak current wells, pipe wells, and stairways. Due to differences in the transmit power of the RRU port, the length of the two cables, and the loss of passive components, it will cause There is a certain power imbalance between the two channels of the dual-channel indoor distribution system, which affects the accuracy of terminal signal estimation, thereby reducing MIMO performance.
电源方面:由于BBU到RRU之间信号只用一个光纤就可以,但BBU与RRU之间的动力如何解决是3G室内分布系统的一个大问题。现在有的运营商采用直流升压远供的方案,一些运营商采取了逆变器方案,都代表了运营商对3G通讯的BBU+RRU架构下供电模式的探索。但远供存在防雷、防盗、压降、损耗、安全、成本高等缺点,在实际应用中数量并不多。In terms of power supply : Since the signal between the BBU and the RRU can only use one optical fiber, how to solve the power between the BBU and the RRU is a big problem in the 3G indoor distribution system. Now some operators adopt the DC step-up remote power supply solution, and some operators adopt the inverter solution, which represent the exploration of the power supply mode under the BBU+RRU architecture of 3G communication. However, remote supply has disadvantages such as lightning protection, anti-theft, voltage drop, loss, safety, and high cost, and there are not many in practical applications.
在前期的建设中,由于对3G室内分布系统的电池备电保障考虑不足,建站初期大量采用交流市电直接引入,没有配置后备电源和蓄电池组。在交流停电后没有供电保障,导致室内分布系统经常因市电中断后断电退服,严重影响网络的运行质量和可靠性。In the early stage of construction, due to insufficient consideration of the battery backup power guarantee of the 3G indoor distribution system, a large number of AC mains were directly introduced into the station at the initial stage of construction, and no backup power supply and battery pack were configured. There is no power supply guarantee after the AC power outage, resulting in the indoor distribution system often being out of service due to power outages after mains power outages, which seriously affects the operation quality and reliability of the network.
室内分布场景,按照设备的供电制式可以分为交流供电和直流供电,按照供电方式可以分为集中供电和分散供电。交流供电方式,目前有直接交流供电没有电池备电和采用UPS供电两种情况。第一种情况在早期较多,随着对3G室内分布供电保障的重视,直接交流市电供电的越来越少。由于UPS的电池管理功能较弱,运营商普遍不太认可UPS方案。就像最近几年室外基站大量采用室外开关电源代替室外UPS一样,在3G室内分布的应用场景下,采用UPS供电的情况很少。Indoor distribution scenarios can be divided into AC power supply and DC power supply according to the power supply system of the equipment, and can be divided into centralized power supply and decentralized power supply according to the power supply mode. AC power supply mode, currently there are two cases of direct AC power supply without battery backup and UPS power supply. The first situation was more common in the early stage. With the emphasis on 3G indoor distributed power supply guarantee, direct AC power supply is less and less. Due to the weak battery management function of UPS, operators generally do not approve of UPS solutions. Just as outdoor base stations have largely used outdoor switching power supplies instead of outdoor UPSs in recent years, in the application scenarios of 3G indoor distribution, UPS power supply is rarely used.
(1)集中式供电解决方案(1) Centralized power supply solution
集中式供电解决方案采用一套电源系统,既给BBU供电,同时通过拉远的方式对远端RRU进行供电。方案的优点是:电源集中、便于维护、节省设备投资;缺点是:拉远距离有一定的限制、线路损耗比较大,一般推荐的拉远距离在100米以内。The centralized power supply solution adopts a power supply system, which not only supplies power to the BBU, but also supplies power to the remote RRU in a remote manner. The advantages of the solution are: centralized power supply, easy maintenance, and equipment investment savings; the disadvantages are: there is a certain limit to the remote distance, and the line loss is relatively large.

本发明依据覆盖的优劣是衡量移动通信网络最基础的指标,设计一套全新有源+无源+有源的四网融合室内分布系统,该系统即可以满足多种室内话务量的深度覆盖。即可以满足话务密集地区的需求;同时也可以满足商业办公楼等中等话务量地区和地下停车场等话务量不高的地区需求。According to the quality of coverage, which is the most basic index to measure the mobile communication network, the present invention designs a new set of active + passive + active four-network fusion indoor distribution system, which can meet the depth of various indoor traffic cover. It can meet the needs of traffic-intensive areas; at the same time, it can also meet the needs of areas with low traffic such as commercial office buildings and underground parking lots.
全新四网融合室内分布系统将无线领域与电源领域相融合来实现GSM、TD-SCDMA、WLAN与TD-LTE四网并存与四网间协同发展,从而从根本上解决移动通信三个基本原则。The new four-network fusion indoor distribution system integrates the wireless field and the power supply field to realize the coexistence of GSM, TD-SCDMA, WLAN and TD-LTE four-network and the coordinated development of the four-network, so as to fundamentally solve the three basic principles of mobile communication.
1.无线方面1. Wireless
针对目前大部分室内分布系统的RRU都放置在走线间、弱电井、管道井、楼梯口等环境较差的位置的问题。Aiming at the problem that the RRUs of most of the indoor distribution systems are placed in places with poor environments such as wiring rooms, weak current wells, pipe wells, and stairways.
所以,本发明的技术核心就是首先解决RRU的安装问题。本发明通过四网融合室内分布蛛网模式供电与无线信号覆盖的装置与系统可以使所有RRU直接前移置到覆盖区域范围进行安装。这样就可以减少天线、合路器等无源器件以及天馈线缆长度的数量,提高室内分布系统有针对性的建设能力,并使RRU起到应起的作用。全面提高室内分布吸收流量、承载用户的能力。从而从根本上解决四网融合后由于RRU端口发射功率、两路线缆长度和无源器件损耗存在差异,将导致双通道室分系统的两通道之间存在一定的功率不平衡,影响到终端信号估计的准确度,从而降低MIMO性能的问题,以及3G与TD-LTE深度覆盖的问题。Therefore, the technical core of the present invention is to firstly solve the installation problem of the RRU. In the present invention, the device and system for indoor distribution of cobweb mode power supply and wireless signal coverage through the integration of four networks can make all RRUs be directly moved forward to the coverage area for installation. In this way, the number of passive components such as antennas and combiners and the length of antenna feeder cables can be reduced, the targeted construction capability of the indoor distribution system can be improved, and the RRU can play its due role. Comprehensively improve the ability of indoor distribution to absorb traffic and carry users. So as to fundamentally solve the problem that due to the differences in the transmission power of the RRU port, the length of the two cables, and the loss of passive components after the four-network integration, there will be a certain power imbalance between the two channels of the dual-channel indoor distribution system, which will affect the terminal. The accuracy of signal estimation, thereby reducing the problem of MIMO performance, and the problem of deep coverage of 3G and TD-LTE.
在提高室内分布系统有针对性的建设能力后,本发明的技术核心就是借鉴大自然蜘蛛所织成的丝网,若有昆虫投网,透过信号丝的振动便可闻讯而来取食的原理,设计了四网融合室内分布系统部分零话务区域进行分时、分段、无线与电源设备休眠的绿色环保节能减排运行模式。其工作原理简述如下:After improving the targeted construction ability of the indoor distribution system, the technical core of the present invention is to learn from the silk webs woven by natural spiders. If insects cast their nets, they can hear the information and feed through the vibration of the signal wires. Based on the principle, a green environment-friendly energy-saving and emission-reducing operation mode is designed for time-sharing, segmentation, wireless and power supply equipment sleep in part of the zero-traffic area of the four-network fusion indoor distribution system. Its working principle is briefly described as follows:

Distributed micro AC and DC cobweb 48v and switching power supply on the cobweb, cobweb power supply dynamic balance and equalization sending module, cobweb wireless network coverage dynamic chain detection module, 2G/4G/3G-RRU, cobweb power supply dynamic balance and equalization receiving module, POE- WLAN, 2G/4G multi-frequency active filter isolation combiner, 2G/WLAN multi-frequency active filter isolation combiner, 3G/4G multi-frequency active filter isolation combiner, 2G/4G active signal amplifier coupler , The power divider forms the vibration monitoring point of the spider web signal wire.
当四网融合室内分布蛛网模式供电与无线信号覆盖的装置与系统不同区域蛛网监测点测试出现分时、分段零话务时。蜘蛛(即分布式微型交直流蛛网48v开关电源、2G/3G/4G-BBU/WLAN-ONU)依据丝网电压电流与振动监测点上下行功率、话务量变化来控制实现电源无线等有源设备室内分布蛛网系统绿色环保休眠节能减排模式运行。When the four-network fusion indoor distributed cobweb mode power supply and wireless signal coverage are tested with cobweb monitoring points in different areas of the system, time-sharing and segmental zero traffic occurs. Spider (i.e. distributed miniature AC-DC cobweb 48v switching power supply, 2G/3G/4G-BBU/WLAN-ONU) is controlled according to the voltage and current of the wire mesh and the vibration monitoring point uplink and downlink power, and traffic changes to realize power wireless and other active The cobweb system distributed in the equipment room operates in a green, environmentally friendly, dormant, energy-saving and emission-reduction mode.
2.电源方面2. Power supply
电源领域利用现网2G、3G系统的天馈线与FTTH光缆建立相关的无线网络覆盖蛛网供电通道。在室内弱覆盖的地区在给四网核心设备供电的同时,也给发射端和接收端不同功率大小无线网络信号放大器件与有源单极/双极天线供电。In the field of power supply, the antenna feeder and FTTH optical cable of the existing network 2G and 3G systems are used to establish a related wireless network covering the cobweb power supply channel. In areas with weak indoor coverage, while supplying power to the core equipment of the four networks, it also supplies power to wireless network signal amplifiers and active monopole/dipole antennas of different power levels at the transmitter and receiver.
本发明在实际中采取集中供电和分散供电相结合的一种全新C-RAN分布式蛛网室内供电方案,是目前对现有供电技术的进一步创新。本发明具有“集中化(Centralize)、协作化Collaborative)、云计算化(Cloud)”特征的“绿色节能(Clean)”的无线接入网络的多级不同供电电压等级的构架。例如,针对一栋几十层高楼的室内分布,靠近BBU的RRU同BBU使用同一套分布式微型交直流蛛网低电压36-48v主开关电源,远离BBU的RRU可以在楼的中部集中1-2套壁挂式蛛网上的分布式微型交直流蛛网高电压50-60v从开关电源,就近拉远进行供电。主从电源通过蛛网上的蛛网供电动态平衡均衡发送接收模块进行连接并进行电压控制输出,这种方式弥补了集中供电和分散供电的不足,解决了拉远距离的问题并降低投资成本。In practice, the present invention adopts a new C-RAN distributed spider web indoor power supply scheme combining centralized power supply and decentralized power supply, which is a further innovation of the existing power supply technology. The present invention has the characteristics of "centralization (Centralize), collaborative (Collaborative), cloud computing (Cloud)" and a "green energy-saving (Clean)" wireless access network with multiple levels of different power supply voltage levels. For example, for the indoor distribution of a building with dozens of floors, the RRUs close to the BBU and the BBU use the same set of distributed micro-AC/DC low-voltage 36-48v main switching power supply, and the RRUs far away from the BBU can be concentrated 1-2 in the middle of the building. The distributed miniature AC and DC spider webs on the set of wall-mounted spider webs have a high voltage of 50-60v from the switching power supply, and the power supply is carried out at the nearest distance. The master-slave power supply is connected through the cobweb power supply dynamic balance and equalization sending and receiving module and performs voltage control output. This method makes up for the shortage of centralized power supply and decentralized power supply, solves the problem of long distance and reduces investment costs.

本发明的技术核心就是借鉴大自然蜘蛛所织成的丝网,若有昆虫投网,透过信号丝的振动便可闻讯而来取食的原理设计了四网融合室内分布供电系统。The technical core of the present invention is to design a four-net fusion indoor distributed power supply system based on the principle that insects cast their nets through the vibration of the signal wires to feed on the silk webs woven by natural spiders.

Through the cobweb power supply on the signal wire, the dynamic balance and equalization sending and receiving modules A, B, C, D, E, F cooperate with the distributed micro AC and DC cobweb 48v master-slave switching power supply (spider) to form a new set of dynamic divergence Type power supply spider web, dynamic convergent power supply spider web, dynamic closed power supply spider web. According to the importance of the loads carried by the screens at all levels, a differentiated power supply output guarantee mode is adopted, so as to achieve the realization of the automatic configuration of the best power supply scheme for the entire distributed system.
3G室内分布系统方案的选择主要取决于建筑物自身的特点,例如:建筑物的规模、建筑物内的环境情况、建筑物的用途等。每个建筑物均有各自不同的特点,所以每个建筑物的室内建设方案都是视具体情况量身定做的。The choice of the 3G indoor distribution system solution mainly depends on the characteristics of the building itself, such as: the scale of the building, the environment inside the building, and the purpose of the building. Each building has its own unique characteristics, so the interior construction plan of each building is tailor-made according to the specific situation.
从狭义上来讲,室内覆盖问题仅仅是对室内覆盖盲区的改善,解决电话打不出去的问题。从广义上来讲,室内覆盖问题包括对室内移动通信话音质量、网络质量、系统容量的改善,解决打电话质量的问题。除了对诸如地下室,一、二层等通信盲区提供覆盖外,同时也应对建筑物的高层部分因接收到来自多方向的杂乱不稳定信号而导致掉话、断续、切换不成功等方面进行改善。对于高话务量的商务、商贸中心,还应该解决室内话务吸收及拥塞问题。因此,室内覆盖信号的改善对于扩大覆盖、提高覆盖质量、提高接通率、减少弱信号掉话、减少同频干扰也有很大的帮助。同时,室内覆盖作为一种扩容手段,在分担室外基站话务,增加网络容量,使室内话务在室内吸收,减少同频干扰也起很大作用。另外,良好的室内覆盖,对于提高网络运营形象,为用户提供更好更完善的随时随地通信服务,提高企业竞争力具有很大的意义。In a narrow sense, the problem of indoor coverage is only the improvement of indoor coverage blind spots, and solves the problem of inability to make calls. In a broad sense, indoor coverage issues include improving the voice quality, network quality, and system capacity of indoor mobile communications, and solving the problem of call quality. In addition to providing coverage for communication blind areas such as the basement, the first and second floors, it is also necessary to improve the high-rise parts of the building due to reception of messy and unstable signals from multiple directions, resulting in call drop, intermittent, and unsuccessful switching. . For business and trade centers with high traffic volume, the problems of indoor traffic absorption and congestion should also be solved. Therefore, the improvement of indoor coverage signals is also of great help to expand coverage, improve coverage quality, increase connection rate, reduce weak signal drop calls, and reduce co-channel interference. At the same time, indoor coverage, as a means of capacity expansion, plays an important role in sharing the traffic of outdoor base stations, increasing network capacity, allowing indoor traffic to be absorbed indoors, and reducing co-channel interference. In addition, good indoor coverage is of great significance for improving the image of network operation, providing users with better and more complete communication services anytime and anywhere, and improving the competitiveness of enterprises.
在室内覆盖系统中,可以作为信号源的有:蜂窝基站、直放站和射频远端模块等,其中微蜂窝基站和直放站应用的最多。In the indoor coverage system, signal sources can be: cellular base stations, repeaters, and radio frequency remote modules, among which microcellular base stations and repeaters are most widely used.
蜂窝系统的优点是信号稳定、可靠,通信质量好,可以有效地吸收话务量,适用于话务繁忙区域的室内覆盖;缺点是工程一次性投资大,需要解决传输线路等问题,受地理位置条件的限制。蜂窝型室内分布系统大多应用于星级酒店、高级写字楼等比较大型的室内建筑。The advantage of the cellular system is that the signal is stable and reliable, the communication quality is good, it can effectively absorb the traffic, and it is suitable for indoor coverage in areas with heavy traffic. Conditional restrictions. The cellular indoor distribution system is mostly used in relatively large indoor buildings such as star hotels and high-end office buildings.
直放站安装方便,投资最小,但有可能造成系统内与外界网络的干扰,同时在系统服务区域话务量较高时会增加施主基站小区的负担,而且在有源电分布系统中为避免多个放大器级联引起的质量下降,一般不再级联干线放大器,限制了系统的服务区域。直放站作为信号源接入室内分布系统,是利用施主天线空间耦合或利用耦合器件直接耦合存在富余容量的基站信号,再利用直放站设备对接收到的信号进行放大,为室内分布系统提供信号源。The repeater is easy to install and has the least investment, but it may cause interference between the system and the external network. At the same time, when the traffic volume in the system service area is high, it will increase the burden on the donor base station. In addition, in the active power distribution system to avoid The quality degradation caused by the cascading of multiple amplifiers is generally not cascaded with the trunk amplifier, which limits the service area of the system. The repeater is used as a signal source to access the indoor distribution system. It uses the donor antenna space coupling or the coupling device to directly couple the base station signal with surplus capacity, and then uses the repeater equipment to amplify the received signal to provide indoor distribution system. signal source.
射频远端模块通过光纤将基站的射频部分拉远,实现基站射频部分与基带部分的分离,使得大容量基站可以集中放置在可获取的中心机房,基带部分进行集中处理,射频部分光纤拉远放置在规划确定的站点上,这种技术也称为射频拉远。采用这种技术,可以节省常规建网方式中需要的大量机房,节约基带单元的投资,减小馈线损耗。The radio frequency remote module pulls the radio frequency part of the base station far away through the optical fiber to realize the separation of the radio frequency part and the baseband part of the base station, so that the large-capacity base station can be centrally placed in an accessible central computer room, the baseband part is processed centrally, and the radio frequency part is placed far away by optical fiber On planned sites, this technology is also called remote radio. Using this technology can save a large number of computer rooms required in conventional network construction methods, save investment in baseband units, and reduce feeder loss.
室内覆盖系统在选择信号源时,主要应根据无线环境情况、要服务的区域的话务情况和所选室内覆盖系统类型确定。选取信号源时,需要综合考虑目标话务量、覆盖要求、电源要求、机房要求、具体场景特点要求等因素,最终采用既可达到所需的覆盖要求又可合理控制成本的分布系统。其中最重要的考虑因素为容量和覆盖:从容量角度考虑信号源的选取,主要是根据信号源可以支持的话务量和总的等效语音话务量需求来决定。一般对较小的室内覆盖系统,在话务量较低时可选用直放站从周边小区耦合信号;对较大的室内覆盖系统,根据其可能达到的话务情况及安装条件选用微基站或宏蜂窝基站作为信源。When selecting a signal source for an indoor coverage system, it should be determined mainly based on the wireless environment, traffic conditions in the area to be served, and the type of indoor coverage system selected. When selecting a signal source, it is necessary to comprehensively consider factors such as target traffic volume, coverage requirements, power supply requirements, equipment room requirements, and specific scene characteristic requirements, and finally adopt a distribution system that can meet the required coverage requirements and reasonably control costs. The most important considerations are capacity and coverage: from the perspective of capacity, the selection of signal source is mainly determined according to the traffic volume that the signal source can support and the total equivalent voice traffic demand. Generally, for smaller indoor coverage systems, repeaters can be used to couple signals from surrounding cells when the traffic volume is low; for larger indoor coverage systems, micro base stations or micro base stations can be selected according to the possible traffic conditions and installation conditions. The macro cell base station is used as the source.
从覆盖角度考虑信号源的选取时,对于低话务密度、小规模覆盖且较为封闭的场景,优先选用直放站作为信号源;对于中等话务密度和中等覆盖规模的场景,可以选用微基站作为信号源;对于高话务密度和大覆盖规模的场景,建议采用选用宏基站+远端射频模块(RRU)作为信号源。除了容量和覆盖,还要考虑机房和电源等配套设施,综合这些因素后最终决定采用那种方式进行室内覆盖。When considering the selection of signal sources from the perspective of coverage, for low traffic density, small-scale coverage and relatively closed scenarios, repeaters are preferred as signal sources; for medium traffic density and medium coverage scenarios, micro base stations can be selected As a signal source; for scenarios with high traffic density and large coverage scale, it is recommended to use a macro base station + remote radio frequency unit (RRU) as a signal source. In addition to capacity and coverage, supporting facilities such as computer rooms and power supplies must also be considered. After considering these factors, it is finally decided which method to use for indoor coverage.
