技术领域Technical Field
本发明涉及通信技术领域,尤其是指一种邻区干扰检测方法、装置、边缘服务设备及接入网设备。The present invention relates to the field of communication technology, and in particular to a method and device for detecting neighboring cell interference, edge service equipment, and access network equipment.
背景技术Background technique
无线网络运维中的路测(Drive Test)是进行无线网络性能评估、网络优化的重要手段。对于评估无线网络中的业务性能、网络覆盖、网络干扰,发现网络故障均起到重要作用,也为网络的合理规划和优化提供依据。路测费时费力,需要人工驾驶车辆,携带路测仪在测试区域道路遍历行驶采集数据。除道路外的覆盖区域难以到达,不能反映所有覆盖区域的情况。路测作为一种评估手段,只是偶发性地使用,数据只反映测量当前时间的情况,受瞬时变化因素的影响大,难以大量统计反映网络的统计特征。并且,路测仅依靠终端侧的测量,是没有与网络侧的协同不能同步精细获得上行测量数据。进一步,路测是在终端进行实际业务的情况下进行,会占用网络资源。Drive Test in wireless network operation and maintenance is an important means of wireless network performance evaluation and network optimization. It plays an important role in evaluating service performance, network coverage, network interference, and discovering network faults in wireless networks, and also provides a basis for reasonable network planning and optimization. Drive testing is time-consuming and labor-intensive, requiring manual driving of vehicles and carrying drive testers to traverse the roads in the test area to collect data. Coverage areas other than roads are difficult to reach, and cannot reflect the situation of all coverage areas. Drive testing, as an evaluation method, is only used occasionally, and the data only reflects the situation at the current time of measurement. It is greatly affected by instantaneous changes, and it is difficult to reflect the statistical characteristics of the network in large quantities. In addition, drive testing relies only on measurements on the terminal side, and there is no coordination with the network side, and it is impossible to obtain uplink measurement data synchronously and precisely. Furthermore, drive testing is performed when the terminal is performing actual business, which will occupy network resources.
为了更便利地进行路测,减少运营成本,现有技术中引入了MDT(Minimization ofDrive Test,最小化路测)技术,通过普通用户的商用终端上报测量报告、基站收集测量结果的方式来获取网络优化所需要的相关数据。采用MDT可以收集传统路测无法收集的全区域的测量信息。但是,MDT需要商用终端的配合。In order to facilitate drive testing and reduce operating costs, the existing technology introduces the MDT (Minimization of Drive Test) technology, which obtains the relevant data required for network optimization by reporting measurement reports through the commercial terminals of ordinary users and collecting measurement results by the base station. MDT can collect measurement information of the entire area that traditional drive testing cannot collect. However, MDT requires the cooperation of commercial terminals.
此外,不管是采用路测还是采用MDT,因为主要依靠终端侧的测量,系统内的上行干扰是无法区分干扰来源的。In addition, no matter whether drive testing or MDT is used, because it mainly relies on the measurement on the terminal side, the source of uplink interference in the system cannot be distinguished.

具体实施方式Detailed ways
为使本发明要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.
同频组网情况下,网络中的系统内干扰主要来源是相邻小区间、相邻小区的用户间相互的干扰,其干扰产生机制如图1所示。由于无线信号的自由传播,受天线方位、天线倾角、空间损耗、信号功率、UE与天线间的距离等因素影响,图1中的终端(UE)发送的信号可能被Cell0、Cell1接收,UE也可能接收到Cell0、Cell1两个小区的信号。在下行方向,Cell0下接入的UE接收到Cell1下行信号成为对自己的下行干扰;在上行方向,Cell0下接入的UE所发送的信号是Cell0的有用信号,也成为对Cell1的上行干扰。In the case of co-frequency networking, the main source of intra-system interference in the network is the mutual interference between adjacent cells and users in adjacent cells. The interference generation mechanism is shown in Figure 1. Due to the free propagation of wireless signals, affected by factors such as antenna azimuth, antenna tilt, spatial loss, signal power, and the distance between UE and antenna, the signal sent by the terminal (UE) in Figure 1 may be received by Cell0 and Cell1, and the UE may also receive signals from both Cell0 and Cell1. In the downlink direction, the UE connected to Cell0 receives the downlink signal of Cell1, which becomes downlink interference to itself; in the uplink direction, the signal sent by the UE connected to Cell0 is a useful signal of Cell0, which also becomes uplink interference to Cell1.
同理,更多的邻区情况下,会有更复杂的干扰相互叠加。合理的网络规划需要充分考虑天线方位、天线倾角、小区覆盖范围、邻区重叠覆盖度、下行功率、上行功率控制等各种因素,使得邻区间的干扰尽量地降低。但实际情况是网络规划通常难以完全避免系统内的干扰。因此,分析小区是否存在严重的系统内干扰以及判别干扰来源,是网络智能化的重要应用场景。Similarly, with more neighboring cells, there will be more complex interference superimposed on each other. Reasonable network planning needs to fully consider various factors such as antenna azimuth, antenna tilt, cell coverage, overlapping coverage of neighboring cells, downlink power, uplink power control, etc., so as to minimize the interference between neighboring cells. However, the actual situation is that it is usually difficult to completely avoid interference within the system in network planning. Therefore, analyzing whether there is serious interference within the system in the cell and identifying the source of interference are important application scenarios of network intelligence.
为了达到上述目的,如图2所示,本发明实施例提供一种邻区干扰检测方法,由设置于接入网侧的边缘服务设备执行,所述方法包括:In order to achieve the above object, as shown in FIG. 2, an embodiment of the present invention provides a neighboring cell interference detection method, which is performed by an edge service device arranged on the access network side, and the method includes:
步骤201,采集多个小区的信令,得到各个小区对应的信道探测参考信号SRS参数;Step 201, collecting signaling of multiple cells to obtain channel sounding reference signal SRS parameters corresponding to each cell;
可选地,接入网中的边缘服务设备与基带单元BBU建立连接,根据邻区列表,交互不在本地的邻区的SRS参数;Optionally, the edge service device in the access network establishes a connection with the baseband unit BBU, and exchanges SRS parameters of neighboring cells that are not local according to the neighboring cell list;
步骤202,采集目标小区接收的SRS数据;Step 202, collecting SRS data received by the target cell;
步骤203,使用各个小区的SRS参数对目标小区接收到的SRS数据进行信号检测和功率测量,得到目标小区的上行干扰值。Step 203: Use the SRS parameters of each cell to perform signal detection and power measurement on the SRS data received by the target cell to obtain the uplink interference value of the target cell.
本发明实施例中,SRS作为上行参考信号具有众多用途,用户间通过不同的时频资源位置、不同的SRS序列、不同的循环移位进行区分。由于生成的SRS序列具有正交性,根据用户不同的SRS参数,只要知道SRS参数,对用户间混合叠加在一起的SRS数据可以进行准确区分,且无论用户来自哪个小区。In the embodiment of the present invention, SRS has many uses as an uplink reference signal, and users are distinguished by different time-frequency resource positions, different SRS sequences, and different cyclic shifts. Since the generated SRS sequence has orthogonality, according to different SRS parameters of users, as long as the SRS parameters are known, the SRS data mixed and superimposed between users can be accurately distinguished, regardless of which cell the users come from.
可选地,该SRS参数用于对应小区按照本小区的SRS参数进行接收到的SRS数据进行功率测量。例如,小区的SRS参数包括以下至少一项:SRS的时频资源位置、SRS序列、循环移位。Optionally, the SRS parameter is used for the corresponding cell to perform power measurement on the SRS data received according to the SRS parameter of the cell. For example, the SRS parameter of the cell includes at least one of the following: the time-frequency resource position of the SRS, the SRS sequence, and the cyclic shift.
可选地,目标小区接收的SRS数据包括:目标小区的SRS以及其他相邻小区的SRS。Optionally, the SRS data received by the target cell includes: the SRS of the target cell and the SRS of other neighboring cells.
如图1所示,同频组网情况下,虽然Cell0下接入的UE发送的上行信号可能对Cell1造成干扰,但对Cell1接收到的信号采用Cell0 UE的参数进行接收处理仍然可以对信号进行信道估计、功率测量。信号的接收处理并不局限于物理上射频单元与基带单元BBU、小区的连接关系,有相应的参数、有射频单元接收到的信号数据就可以通过信道估计、功率测量判断此射频单元是否接收到参数对应的用户的信号以及功率大小。As shown in Figure 1, in the case of co-frequency networking, although the uplink signal sent by the UE accessed under Cell0 may cause interference to Cell1, the signal received by Cell1 can still be channel estimated and the power measured by using the parameters of Cell0 UE for reception processing. The reception and processing of the signal is not limited to the physical connection relationship between the RF unit and the baseband unit BBU and the cell. With the corresponding parameters and the signal data received by the RF unit, it is possible to determine whether the RF unit has received the user's signal corresponding to the parameters and the power through channel estimation and power measurement.
针对以上问题,本方案将SRS应用于邻区间的上行干扰测量、上行干扰来源识别,因此需要打破数据与参数在小区内的固定对应关系,本方案设计以下数据及信令采集方案。To address the above issues, this solution applies SRS to uplink interference measurement and uplink interference source identification between neighboring cells. Therefore, it is necessary to break the fixed correspondence between data and parameters within the cell. This solution designs the following data and signaling collection scheme.
本方案中,在基带单元集中部署的近端机房部署边缘服务设备(也可以称为边缘服务器)负责信令和数据的采集及分析,汇总数据及信令,打破小区间的信令壁垒,打破数据与参数在小区内的一一对应关系。基于信令得到各小区的SRS参数。In this solution, edge service equipment (also called edge server) is deployed in the near-end machine room where the baseband unit is centrally deployed. It is responsible for the collection and analysis of signaling and data, aggregates data and signaling, breaks the signaling barriers between cells, and breaks the one-to-one correspondence between data and parameters within the cell. The SRS parameters of each cell are obtained based on the signaling.
作为一个可选实施例,步骤203包括:As an optional embodiment, step 203 includes:
使用各个小区的SRS参数对目标小区接收到的SRS数据进行信号检测和功率测量,得到目标小区接收到的各个邻小区终端的SRS的功率;Use the SRS parameters of each cell to perform signal detection and power measurement on the SRS data received by the target cell, and obtain the power of the SRS of each neighboring cell terminal received by the target cell;
根据预设时间段内目标小区接收邻小区终端的SRS的功率的平均值,得到目标小区的上行干扰值和干扰来源。The uplink interference value and interference source of the target cell are obtained according to the average value of the power of the SRS of the neighboring cell terminal received by the target cell within the preset time period.
可选地,所述目标小区包括所述多个小区中的一个或多个。Optionally, the target cell includes one or more of the multiple cells.
无线网络中为了满足移动性需求,覆盖区域通常为连续部署,如图3所示,某一位置下行可能接收到多个小区的信号,上行信号也可能被多个小区接收到。这也是实际网络中的一般情况。例如,当需要知道Cell0接收到的信号中,是否有接入小区为CellN的用户所发送的信号时,就需要对Cell0接收的信号,使用CellN的用户参数进行信号接收及功率测量。N取1,2,……时,即对Cell0接收到的信号遍历地检测是否有来自其他小区的用户的信号。对所有小区接收的信号均按所有小区用户参数进行遍历性信号检测后可以得到表1。In order to meet the mobility requirements in wireless networks, the coverage area is usually deployed continuously. As shown in Figure 3, a certain location may receive downlink signals from multiple cells, and uplink signals may also be received by multiple cells. This is also the general situation in actual networks. For example, when you need to know whether there are signals sent by users whose access cell is CellN among the signals received by Cell0, you need to use the user parameters of CellN to perform signal reception and power measurement on the signals received by Cell0. When N is 1, 2, ..., the signal received by Cell0 is ergodicly detected to see whether there are signals from users in other cells. After performing ergodic signal detection on the signals received by all cells according to the user parameters of all cells, Table 1 can be obtained.
表1遍历性功率测量Table 1 Ergodic power measurement
其中,表1中RSRPM-N的意义为小区CellM接收到的来自小区CellN的用户所发送信号的功率。例如RSRP0-1意义为小区Cell0接收到的小区Cell1中的UE发送的信号的功率。In Table 1, RSRP MN means the power of a signal sent by a user in cell CellN and received by cell CellM. For example, RSRP 0-1 means the power of a signal sent by a UE in cell Cell1 and received by cell Cell0.
单个用户由于位置分布等因素,不足以反应网络的一般情况,因此需要在一定时间段内对邻区所有用户进行功率测量并统计平均,更普遍意义上的反应各时间段内用户通常分布情况下的小区间用户的相互干扰功率。同频组网网络中,来自非本小区用户发送的信号对本小区来说完全是干扰,因此以上测量的信号功率完全视为干扰功率。Due to factors such as location distribution, a single user is not enough to reflect the general situation of the network. Therefore, it is necessary to measure the power of all users in the neighboring area within a certain period of time and statistically average it, which more generally reflects the mutual interference power of users between cells under the general distribution of users in each time period. In the same frequency networking network, the signal sent by users outside the cell is completely interference to the cell, so the signal power measured above is completely regarded as interference power.
根据统计结果,在不依赖路测及MDT的情况下,独立常态化测量评估上行方向系统内干扰及来源,在TDD系统中为覆盖(弱覆盖、重叠覆盖)优化、切换参数优化、天线工参优化、上行功控优化等网络优化提供依据。According to the statistical results, without relying on drive tests and MDT, independent normalized measurements are performed to evaluate the interference and its sources within the uplink system, providing a basis for network optimization such as coverage (weak coverage, overlapping coverage) optimization, switching parameter optimization, antenna engineering parameter optimization, and uplink power control optimization in the TDD system.
作为一个可选实施例,步骤202包括:As an optional embodiment, step 202 includes:
按照第一条件信息,对目标小区的原始通道级时域数据或频域数据进行采集处理,得到目标小区接收到的SRS数据。According to the first condition information, original channel-level time domain data or frequency domain data of the target cell is collected and processed to obtain SRS data received by the target cell.
其中,所述第一条件信息包括以下至少一项:The first condition information includes at least one of the following:
小区;Community;
通道;aisle;
帧号;Frame number;
时隙号;Time slot number;
时隙内符号;Symbols within a time slot;
采集周期。Collection cycle.
本发明实施例中,数据采集按指定条件对原始通道级时域数据或频域数据进行采集处理。其中,指定条件包括但不限于:小区、通道、帧号、时隙号、时隙内符号、采集周期。通过以上指定条件的限制,将大大减小数据采集量。SRS为周期性信号,且干扰测量不依赖于单次单个终端,而是采用采样统计方式。因此,采集周期可以间歇性采样,如每1024无线帧连续采样前160ms,每2048无线帧连续采样前320ms等。In an embodiment of the present invention, data acquisition is performed on the original channel-level time domain data or frequency domain data according to specified conditions. The specified conditions include, but are not limited to: cell, channel, frame number, time slot number, symbol in time slot, acquisition period. The amount of data acquisition will be greatly reduced by limiting the above specified conditions. SRS is a periodic signal, and interference measurement does not depend on a single terminal at a time, but adopts a sampling and statistical method. Therefore, the acquisition period can be intermittently sampled, such as 160ms before continuous sampling of every 1024 wireless frames, 320ms before continuous sampling of every 2048 wireless frames, etc.
可选地,如图4所示,当前的无线通信网络,基站通常采用射频光纤拉远的连接形式,射频单元(Radio Unit,RU)通过光纤与基带单元(baseband Unit,BBU)连接,基带单元集中部署于附近的机房,则在基带单元集中部署的近端机房部署边缘服务设备(也可以称为边缘服务器),边缘服务器负责信令和数据的采集及分析,汇总数据及信令,打破小区间的信令壁垒,打破数据与参数在小区内的一一对应关系,并利用采集的SRS数据,脱离正常基带处理流程,遍历进行信道估计、功率测量,以分析相邻小区间的上行干扰的方法,可以准确分析上行干扰大小以及干扰来源,从而推动网络智能化。Optionally, as shown in Figure 4, in the current wireless communication network, the base station usually adopts the form of RF optical fiber remote connection. The radio unit (Radio Unit, RU) is connected to the baseband unit (Baseband Unit, BBU) through optical fiber. The baseband unit is centrally deployed in a nearby computer room, and the edge service equipment (also called edge server) is deployed in the proximal computer room where the baseband unit is centrally deployed. The edge server is responsible for the collection and analysis of signaling and data, aggregating data and signaling, breaking the signaling barriers between cells, breaking the one-to-one correspondence between data and parameters in the cell, and using the collected SRS data to deviate from the normal baseband processing process, traverse channel estimation and power measurement to analyze the uplink interference between adjacent cells. The method can accurately analyze the size of uplink interference and the source of interference, thereby promoting network intelligence.
综上,设置于接入网侧的边缘服务设备采集多小区信令,得到各个小区对应的SRS参数,并采集目标小区接收的SRS数据,再使用各个小区的SRS参数对目标小区接收到的SRS数据进行信号检测和功率测量,得到目标小区的上行干扰值;该邻区干扰检测方法为网络自主行为,不依赖于路测终端或商用终端的测量上报,具有更好的可控性和可操作性,且在不增加终端负荷和电耗的情况下可以进行常态化检测。In summary, the edge service equipment set on the access network side collects multi-cell signaling, obtains the SRS parameters corresponding to each cell, and collects the SRS data received by the target cell, and then uses the SRS parameters of each cell to perform signal detection and power measurement on the SRS data received by the target cell to obtain the uplink interference value of the target cell; the neighboring cell interference detection method is a network autonomous behavior, does not rely on the measurement report of the road test terminal or the commercial terminal, has better controllability and operability, and can perform normalized detection without increasing the terminal load and power consumption.
