Description
技术领域 technical field
本发明涉及无线通信领域,特别涉及对网络的测量技术。The invention relates to the field of wireless communication, in particular to the measurement technology for the network.
背景技术 Background technique
近年来移动通信飞速发展,网络规模不断扩大,用户数量急速上升,用户对网络性能质量的要求也不断提高,运行商对网络的管理也从对信号覆盖的定性要求转变为对网络性能指标的定量管理。In recent years, with the rapid development of mobile communication, the scale of the network has continued to expand, the number of users has increased rapidly, and the requirements of users for network performance and quality have also continued to increase. Operators' management of the network has also changed from qualitative requirements for signal coverage to quantitative network performance indicators. manage.
在移动通信网络的建设中,网络规划占据了很重要的位置,良好的网络规化能够大幅度地提升移动通信网络的性能。In the construction of mobile communication networks, network planning occupies a very important position, and good network planning can greatly improve the performance of mobile communication networks.
当然,仅有较完善的网络规化是不够的,因为移动无线网络运行状况动态变化较大,受外界客观环境影响因素较多。用户市场不断扩大,网络不停扩容,网络服务项目的不断增加,城乡建筑的日新月异,使得话务量分布动态变化。因此,需要在建网之后,对移动通信网络进一步维护。其中,网络优化是网络运行维护工作中的一个重要组成部分,其目的就是提高网络通信质量,改善服务形象,充分挖掘网络资源。Of course, a relatively complete network planning is not enough, because the mobile wireless network operation status changes dynamically and is affected by many external objective environment factors. The user market continues to expand, the network continues to expand, network service items continue to increase, and urban and rural buildings change with each passing day, resulting in dynamic changes in traffic distribution. Therefore, it is necessary to further maintain the mobile communication network after the network is built. Among them, network optimization is an important part of network operation and maintenance. Its purpose is to improve network communication quality, improve service image, and fully tap network resources.
随着新技术的发展,码分多址(Code Division Multiple Access,简称“CDMA”)/全球移动通信系统(Global System for mobile Communication,简称“GSM”)网络上开通的业务种类越来越多,不仅包括话音服务,还将会开通无线数据、图像等增值服务项目,向多媒体方向发展。这样,网络的维护质量要求也就越来越高,网络优化的任务越来越重。With the development of new technologies, there are more and more types of services opened on Code Division Multiple Access (CDMA)/Global System for mobile Communication (GSM) networks. It not only includes voice services, but also value-added services such as wireless data and images, and develops in the direction of multimedia. In this way, the maintenance quality requirements of the network are getting higher and higher, and the task of network optimization is getting heavier and heavier.
网络优化是在充分了解网络运行状态的前提下,通过各种技术手段,对网络中不合理的部分进行必要的调整,使网络达到最优运行状态的过程。Network optimization is the process of making necessary adjustments to unreasonable parts of the network through various technical means on the premise of fully understanding the network operation status, so as to make the network reach the optimal operation status.
移动通信网络是一个动态的多维系统,投入使用后,会在以下四个方面发生变化:第一,终端用户的变化,例如用户的地理分布、信令呼叫模型等;第二,网络运行环境的变化,例如新的建筑、道路、植被;第三,网络结构的变化,包括基站分布的变化、系统容量的变化等;第四,应用技术的变化。The mobile communication network is a dynamic multi-dimensional system. After it is put into use, it will change in the following four aspects: first, changes in end users, such as geographical distribution of users, signaling call models, etc.; second, changes in the network operating environment. Changes, such as new buildings, roads, and vegetation; third, changes in network structure, including changes in base station distribution and system capacity; fourth, changes in application technology.
这些变化都会影响到网络指标的变化,因此对网络的相关监测工作及网络优化工作都会随着网络的发展循序渐进地进行,不可能一蹴而就。要充分利用现有的网络设备、资源和容量,最大限度地提高网络的平均服务质量、提高效益,就要不断地进行网络优化工作。These changes will affect the changes of network indicators, so the relevant monitoring work and network optimization work on the network will be carried out step by step with the development of the network, and cannot be completed overnight. To make full use of existing network equipment, resources and capacity, to maximize the average service quality of the network, and to improve efficiency, it is necessary to continuously optimize the network.
对网络进行规划、优化同建立、配置网络一样需要付出巨大的努力。特别是现在正在使用的宽带码分多址(Wideband Code Division Multiple Access,简称“WCDMA”)网络,缺少支持网络维护的流程和工具。通信网络的发展使得如今的网络需要配置和选择的参数比以前显著增加,网络运营者为了得到最合适的设置需要花费大量的时间和金钱。为了运营商在长期演进(Long Term Evolution,简称“LTE”)系统中减少网络规划和优化方面的支出,LTE系统更多地需要支持对于系统进行操作维护的流程和工具。Planning and optimizing the network requires as much effort as establishing and configuring the network. In particular, the Wideband Code Division Multiple Access (WCDMA) network currently in use lacks processes and tools to support network maintenance. The development of communication networks makes the parameters that need to be configured and selected in today's networks significantly increased than before, and network operators need to spend a lot of time and money to obtain the most suitable settings. In order for operators to reduce expenditures on network planning and optimization in a Long Term Evolution ("LTE") system, the LTE system more needs to support processes and tools for operating and maintaining the system.
在LTE中,物理的信道分为专用信道和公共信道两种。专用信道是用户在进行业务的时候使用的信道,可以根据信道质量的反馈实时的进行调整,而公共信道的参数(如功率、调制方式等等)一般都是按照网络建设初期的缺省值进行配置的。一旦网络中的无线环境发生变化(比如修建了高楼、其他的发射塔等等),公共信道的传输就会受到长时间的影响。如果不能及时地调整参数,那么可能会影响网络的性能。In LTE, physical channels are divided into dedicated channels and common channels. Dedicated channels are channels used by users when performing services, and can be adjusted in real time according to channel quality feedback, while public channel parameters (such as power, modulation, etc.) are generally set according to the default values at the initial stage of network construction. configured. Once the wireless environment in the network changes (such as the construction of tall buildings, other transmission towers, etc.), the transmission of public channels will be affected for a long time. If the parameters cannot be adjusted in time, the performance of the network may be affected.
特别是在小区边缘的地方,可能存在移动终端虽然能够接收到导频信号但是其它的下行的公共信道发射功率不足或者误码率/误块率偏高导致用户终端无法正确接收的问题。在这种情况下虽然网络的覆盖没有问题,但是移动终端在小区的边缘是无法正常工作的。这种情况下就需要进行网络优化。Especially at the edge of the cell, although the mobile terminal can receive the pilot signal, there may be a problem that the user terminal cannot receive it correctly due to insufficient transmission power of other downlink common channels or high bit error rate/block error rate. In this case, although there is no problem with the coverage of the network, the mobile terminal cannot work normally at the edge of the cell. In this case, network optimization is required.
在现有技术中,运营商使用特殊的仪器(例如路测仪)在网络内各处进行测试并记录测试所得的数据,然后根据所测数据用于网络规划、优化。In the prior art, operators use special instruments (such as drive testers) to test everywhere in the network and record the data obtained from the test, and then use the measured data for network planning and optimization.
但是这种方法有如下几个缺点:首先路测本身需要花费大量的成本和人力;且要选取合适的路测点并不容易,进行路测不是很方便;另外,由于以上两点,所以在整个网络的生命周期内路测进行的次数也不可能很多。运营者无法及时地知道网络的运营情况,实时性差。However, this method has the following disadvantages: First, the drive test itself requires a lot of cost and manpower; and it is not easy to select a suitable drive test point, and it is not very convenient to conduct a drive test; in addition, because of the above two points, so in It is also impossible to carry out a lot of drive tests in the life cycle of the entire network. Operators cannot know the operation status of the network in a timely manner, and the real-time performance is poor.
除了进行定期路测,运营商还可以在收到用户的意见投诉时,根据投诉的内容对网络的参数进行调整。In addition to conducting regular drive tests, operators can also adjust network parameters according to the content of complaints when they receive complaints from users.
然而这种被动地进行优化的方法使得网络优化速度缓慢、不及时;且由于已经有用户进行投诉,使得用户满意度下降;另外,用户反馈的内容不一定准确,有时候并不能进行正确的优化。However, this passive optimization method makes network optimization slow and untimely; and due to complaints from users, user satisfaction decreases; in addition, the content of user feedback is not necessarily accurate, and sometimes correct optimization cannot be performed .

具体实施方式 Detailed ways
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
本发明各实施方式中,在需要对下行公共信道进行测量时,网络侧向移动终端下发测量下行公共信道的指示;移动终端根据该指示对下行公共信道进行测量,并保存测量结果;在恰当的时机向网络侧上报测量结果,供网络侧进行规划优化时使用,如图1所示。在该过程中无需进行人工操作或采用特殊仪器进行路测,成本较低,且能够进行实时检测,无需在出现相关问题后才进行补救,提高用户的满意程度。In each embodiment of the present invention, when it is necessary to measure the downlink public channel, the network side issues an instruction to measure the downlink public channel to the mobile terminal; the mobile terminal measures the downlink public channel according to the instruction, and saves the measurement result; report the measurement results to the network side at the right time for planning and optimization on the network side, as shown in Figure 1. In this process, there is no need for manual operation or use of special instruments for road testing, the cost is low, and real-time detection is possible, and there is no need for remediation after related problems occur, which improves user satisfaction.
本发明第一实施方式涉及一种下行公共信道测量方法,如图2所示。The first embodiment of the present invention relates to a downlink common channel measurement method, as shown in FIG. 2 .
在步骤210中,网络侧在需要时,下发测量下行公共信道的指示,可以将该下行公共信道测量指示以广播方式承载在小区广播消息中,下发给小区中的所有移动终端。该指示中包含下行公共信道测量的相关参数:进行测量的终端条件、测量时机、需要测量的信道、测量项目、测量结果保存条件、保存内容。In
进行测量的终端条件:用于指示哪些移动终端需要进行测量,可以指定需要进行测量的移动终端的无线网络临时标识(Radio Network TemporaryIdentity,简称“RNTI”)范围,或者移动终端需要具备的能力,等。符合该终端条件的移动终端根据网络侧的测量指示进行下行公共信道的测量。Terminal conditions for measurement: used to indicate which mobile terminals need to be measured, and can specify the range of Radio Network Temporary Identity ("RNTI" for short) of mobile terminals that need to be measured, or the capabilities that mobile terminals need to have, etc. . A mobile terminal that meets the terminal condition performs downlink common channel measurement according to the measurement instruction from the network side.
需要测量的信道:指示本次测量具体需要测量哪些下行公共信道,包括寻呼指示信道、寻呼信道、辅助广播信道、随机接入响应信道之一以及这四种信道的任意组合。Channels to be measured: Indicate which downlink common channels need to be measured for this measurement, including one of the paging indicator channel, paging channel, auxiliary broadcast channel, random access response channel, and any combination of these four channels.
测量项目:指示需要测量的参数,包括接收信号功率、信号干扰比、误块率。对于不同的信道,其测量项目可以不同。如表1所示,对于寻呼指示信道,其对应的测量项目为误块率,对于寻呼信道、辅助广播信道、和随机接入响应信道,其测量项目可以是接收信号功率、信号干扰比、误块率之一或其任意组合。Measurement items: Indicate the parameters to be measured, including received signal power, signal-to-interference ratio, and block error rate. For different channels, the measurement items can be different. As shown in Table 1, for the paging indicator channel, the corresponding measurement item is the block error rate, and for the paging channel, auxiliary broadcast channel, and random access response channel, the measurement items can be received signal power, signal-to-interference ratio , one of block error rate or any combination thereof.
表1Table 1
测量时机:移动终端进行测量的触发条件,移动终端在满足该测量时机时,开始对下行公共信道的测量。该测量时机包含以下之一或其任意组合:Measurement timing: the triggering condition for the mobile terminal to perform measurement. When the measurement timing is met, the mobile terminal starts to measure the downlink common channel. The measurement occasion includes one or any combination of the following:
1)、移动终端进行小区重选之前,即移动终端根据驻留小区的主导频信道信号质量或者接收信号功率变化自主地决定进行小区重选时。1) Before the mobile terminal performs cell reselection, that is, when the mobile terminal autonomously decides to perform cell reselection according to the signal quality of the dominant pilot channel or the change in received signal power of the cell where it resides.
2)、移动终端进行小区重选之后,驻入重选的小区时。2) After the mobile terminal performs cell reselection, when it camps in the reselected cell.
3)、移动终端在周期性地监测寻呼指示信道时。3) When the mobile terminal periodically monitors the paging indication channel.
4)、移动终端在寻呼指示消息的指示下收到网络侧下发的指示开始检测下行公共信道的寻呼消息时。4) When the mobile terminal receives a paging message from the network side indicating to start detecting the downlink common channel under the instruction of the paging instruction message.
5)、移动终端在收到网络侧下发的指示开始检测下行公共信道的寻呼指示消息时。5) When the mobile terminal receives a paging indication message from the network side indicating to start detecting the downlink common channel.
6)、移动终端进行切换之前,入移动终端收到网络侧的小区切换命令时。6) Before the mobile terminal performs handover, when the mobile terminal receives a cell handover command from the network side.
7)、移动终端切换到新的小区之后,如移动终端向网络侧发送切换完成消息时。7) After the mobile terminal switches to a new cell, for example, when the mobile terminal sends a handover completion message to the network side.
以上测量的时机大多为移动终端在小区边缘的情况,这样能大致确定测量发生的地点,有助于运营商进行后续的网规网优。The timing of the above measurements is mostly when the mobile terminal is at the edge of the cell. This can roughly determine the location where the measurement occurs, which is helpful for operators to carry out subsequent network planning and network optimization.
测量结果保存条件:如果测量结果满足该保存条件,则移动终端将测量数据记录下来,并进行保存。对于每一个需要测量的信道的每一个测量项目都有相应的保存条件。该保存条件可以为测量项目的阀值,如果测量结果低于或高于指定的阀值就认为是满足保存条件。Measurement result storage condition: if the measurement result satisfies the storage condition, the mobile terminal will record the measurement data and save it. There are corresponding storage conditions for each measurement item of each channel that needs to be measured. The storage condition may be a threshold value of the measurement item, and if the measurement result is lower or higher than the specified threshold value, the storage condition is considered to be met.
保存内容:指示在保存测量结果的同时还需要保存哪些信息,如还需要保存进行测量时大致的位置(如切换时的源小区ID和目标小区ID),进行定位测量的信道、测量的项目和错误时间等。网络侧可以根据移动终端测量时所处小区和相邻小区的信息定位测量结果所对应的地理位置。Save content: Indicate what information needs to be saved while saving the measurement results, such as the approximate location of the measurement (such as the source cell ID and target cell ID during handover), the channel for positioning measurement, the measured items and Error time etc. The network side can locate the geographic location corresponding to the measurement result according to the information of the cell where the mobile terminal is in the measurement and the information of the neighboring cells.
根据测量指示中包含的信息的不同,移动终端会对不同的下行公共信道进行不同项目的测量,十分灵活。According to different information included in the measurement instruction, the mobile terminal will perform measurements of different items on different downlink common channels, which is very flexible.
接着进入步骤220,移动终端从广播信道接收该下行公共信道测量指示。Then enter
接着进入步骤230,如果该移动终端满足该测量指示中的终端条件,如该移动终端的C-RNTI在网络侧要求的范围内,或该移动终端具备网络侧要求的能力,则进入步骤240,否则结束本流程。Then enter
在步骤240中,移动终端在满足测量指示中的测量时机时,触发本终端测量指定的下行公共信道的指定测量项目。通过测量时机的限定,使得移动终端通常在进行小区重选时、或驻入重选小区时、或进行小区切换时、或切换到新的小区时,等等处于小区边缘的情况下才进行信道测量,如图3所示。网络侧可以根据该移动终端当前所处小区和相邻小区的信息,定位测量结果所对应的地理位置,而不需要移动终端具备专门的定位功能,使得本方案对进行信道检测的移动终端的要求极低,且不会给移动终端带来明显的负担。In step 240, when the measurement opportunity in the measurement instruction is satisfied, the mobile terminal triggers the terminal to measure the specified measurement item of the specified downlink common channel. By limiting the timing of the measurement, the mobile terminal usually performs channeling when it is performing cell reselection, or when camping in a reselected cell, or when performing cell handover, or when switching to a new cell, etc. measurement, as shown in Figure 3. The network side can locate the geographic location corresponding to the measurement result according to the information of the cell where the mobile terminal is currently located and adjacent cells, without requiring the mobile terminal to have a special positioning function, so that the requirements of this solution for the mobile terminal performing channel detection It is extremely low and does not impose a significant burden on the mobile terminal.
接着进入步骤250,在得到测量结果后,判断该测量结果是否满足测量结果保存条件,如果满足,则进入步骤260,根据保存内容的指示,将该测量结果和保存内容要求的与该测量结果相关联的信息保存在本地,如将该测量结果和测量的信道、测量的项目、错误时间和测量的大致地理位置关联保存在本地,接着进入步骤270;如果不满足则直接进入步骤270,判断本次测量是否结束。进行测量的移动终端在测量时机不再被满足,或已经按照指示完成每个需要测量的信道相应测量项目的测量时,结束本次测量。如测量时机为:移动终端决定进行小区重选时,开始信道测量,则在重选完成后移动终端驻留到重选的小区时,或者移动终端已经按照指示完成每个需要测量的信道相应的测量项目的测量时,结束本次测量。如果本次测量已经结束,则结束本流程;如果本次测量未结束则进入步骤280,继续测量指定的下行公共信道的指定测量项目,接着进入步骤250,继续判断测量结果是否满足保存条件。Then enter
之后,移动终端在进行其它业务时,可以将已保存的内容携带在其它业务的上行消息中上报网络侧。从而尽可能减小移动终端的额外开销,使得进行下行公共信道测量不会增加网络传输资源的额外负担。其中,该移动终端是激活态的移动终端。Afterwards, when performing other services, the mobile terminal can carry the saved content in the uplink message of other services and report to the network side. Therefore, the additional overhead of the mobile terminal is reduced as much as possible, so that the measurement of the downlink common channel will not increase the additional burden of network transmission resources. Wherein, the mobile terminal is an activated mobile terminal.
具体地说,如图4所示,移动终端在需要发送其它业务数据时,进入步骤410,移动终端对所保存的测量结果及相关内容进行检查,删除超过时效的测量结果及相关内容。从而避免上传多余信息,浪费网络侧的传输资源。接着进入步骤420,移动终端判断是否有保存的测量结果需要发送。如果是则进入步骤430,否则结束本流程。在步骤430中,移动终端将已保存的内容作为一个信息元素携带在该其它业务的上行消息中上报网络侧。接着进入步骤440,移动终端删除已上报的信息。Specifically, as shown in FIG. 4, when the mobile terminal needs to send other service data, it enters step 410, and the mobile terminal checks the stored measurement results and related content, and deletes the measurement results and related content that exceed the time limit. This avoids uploading redundant information and wasting transmission resources on the network side. Then enter step 420, the mobile terminal judges whether there is any saved measurement result to be sent. If yes, go to step 430; otherwise, end this process. In step 430, the mobile terminal carries the saved content as an information element in the uplink message of the other service and reports it to the network side. Then enter step 440, the mobile terminal deletes the reported information.
