异频硬切换故障分析方法 Inter-frequency hard handover failure analysis method

技术领域 FIELD

[0001] 本发明涉及移动通信中的切换技术,特别涉及宽带码分多址系统的异频硬切换技术。 [0001] The present invention relates to different mobile communication handover technology, and particularly relates to wideband code division multiple access system frequency hard handover technique.

背景技术 Background technique

[0002]宽带码分多址(Wideband Code Division Multiple Access,简称“WCDMA”)是国际电信联盟(International Telecommunications Union,简称“ ITU”)接纳的全球第三代移动通信的国际标准之一。 [0002] Wideband CDMA (Wideband Code Division Multiple Access, referred to as "WCDMA") is an international standard ITU (International Telecommunications Union, referred to as "ITU") receive a global third generation mobile communications. 也可以说是世界上最早投入商用的第三代移动通信系统,同时是欧洲第三代移动通信系统频分双工(Frequency Division Duplex,简称“FDD”)频段的标准。 It can be said that the world's first commercially available third-generation mobile communication systems, and is Europe's third-generation mobile communication system, frequency division duplex (Frequency Division Duplex, referred to as "FDD") standard band. 由于UMTS米用宽带码分多址(Wideband Code Division Multiple Access,简称“WCDMA”)空中接口技术,因此,通常也把UMTS系统称为WCDMA通信系统。 Because broadband CDMA UMTS meters (Wideband Code Division Multiple Access, referred to as "WCDMA") air interface technology, and therefore, also commonly referred to as a WCDMA communication system of the UMTS system.

[0003] 如图I所示,UMTS系统采用了与第二代移动通信系统类似的结构,由诸如移动手机、便携式电脑、车载式电话之类的用户设备(User Equipment,简称“UE”)、负责处理所有与无线有关的功能的通用移动通信系统地面无线接入网(UMTS Terrestrial Radio AccessNetwork,简称“UTRAN”),以及负责处理UMTS系统内所有的话音呼叫和数据连接,并实现与外部网络的交换和路由功能的核心网(Core Net,简称“CN”)构成。 [0003] As shown in FIG. I, UMTS system uses a second generation mobile communication system with a similar structure, such as a mobile phone, a portable computer, a vehicle-mounted telephone or the like of a user equipment (User Equipment, referred to as "UE"), is responsible for handling all radio-related functions of the universal mobile telecommunication system terrestrial radio access network (UMTS terrestrial radio AccessNetwork, referred to as "UTRAN"), and handles all the voice calls and data connections UMTS system, and with an external network the core network switching and routing functions (core net, referred to as "CN") constitute.

[0004] 其中CN从逻辑上分为电路交换(Circuit Switching,简称“CS”)域和分组交换(Packet Switching,简称“PS” )域。 [0004] where CN is divided into circuit switched (Circuit Switching, referred to as "CS") domain and a packet switched (Packet Switching, referred to as "PS") from the field logic.

[0005] 而UTRAN包含一个或几个无线网络子系统(Radio Network Subsystem,简称“RNS”)。 [0005] the UTRAN includes one or several radio network subsystems (Radio Network Subsystem, referred to as "RNS"). 如图2所不,每一个RNS由一个无线网络控制器(Radio NetworkController,简称“RNC”)和一个或多个基站节点(Node Base Station,简称“NodeB”)组成。 2 do not each RNS consists of a radio network controller (Radio NetworkController, referred to as "RNC") and one or more base station node (Node Base Station, referred to as "NodeB") composition. 其中,RNC与CN之间通过Iu接口连接;NodeB和RNC通过Iub接口连接;RNC之间通过Iur接口连接,Iur接口可以通过RNC之间的直接物理连接或通过传输网连接实现。 Wherein the connection between the RNC and the CN via Iu interface; NodeB and the RNC is connected via the Iub interfaces; via interface Iur, Iur interface or through a transport network between RNC achieved by direct physical connection between the RNC.

[0006] 在上述结构中,RNC负责分配和控制与之相连或相关的NodeB的无线资源,换句话说,即负责控制UTRAN的无线资源,主要完成连接建立和断开、切换、宏分集合并、无线资源管理控制等功能。 [0006] In the above structure, the RNC is responsible for allocation and control of radio resource-related or connected thereto in the NodeB, in other words, responsible for controlling UTRAN radio resources, mainly to complete the connection establishment and disconnection, switching, macro diversity combining, radio resource management control.

[0007] NodeB则负责完成Iub接口和UU接口之间的数据流的转换,同时也参与一部分无线资源管理。 [0007] NodeB is responsible for the completion of the conversion of data flow between the Iub interface and UU interfaces, as well as take part in radio resource management. 具体的说,它包括无线收发信机和基带处理部件,如上所述,通过标准的Iub接口和RNC互连,主要完成UU接口物理层协议的处理。 Specifically, it includes a wireless transceiver and a baseband processing section, as described above, by the RNC, and Iub interface standard are interconnected, the main processing is completed UU Interface physical layer protocol. 它的主要功能是扩频、调制、信道编码及解扩、解调、信道解码,还包括基带信号和射频信号的相互转换等功能。 Its main function is to spread spectrum, modulation, channel coding and despreading, demodulation, channel decoding, further comprising a mutual conversion baseband signal and RF signal functions.

[0008] UE开机后,在一个小区中驻留后便开始接收网络侧的服务,比如接收系统消息和接收寻呼消息。 After the [0008] UE power, resident service starts after the network side is received in a cell, such as a message receiving system and receiving a paging message. 当UE拨打电话或者接听电话的时候,那么UE就会在这个小区发起呼叫,并触发一系列标准接口的流程。 When the UE make a call or answer the phone, the UE will initiate a call in this district, and trigger a series of standard interfaces of the process.

[0009] 在用户接入成功后便开始处于通话状态,但是很多时候用户都是一边打电话一边移动的(这就是移动电话与固定电话的一个区别)。 [0009] In the user access after a successful start in a call, but users are often side of the phone (which is the difference between a mobile phone and fixed phone) while moving. 对于无线通信系统来说,每个小区都是有一定的覆盖范围的,这个覆盖范围与NodeB的发射功率以及小区中用户的多寡有关,一般来说在小区的边缘,由于路径损耗已经很大,所以UE接收到的信号一般都比较弱了,同时NodeB收到UE的发射功率也会相应的很弱,这样就会导致用户通话质量变的很差,甚至由于信号太弱而掉话。 For a wireless communication system, each cell have a certain coverage area, the coverage area of ​​the cell transmit power and the amount of the NodeB user, in general edge of a cell, since the path loss has been great, the UE receives a signal weaker than normal, while the NodeB will receive the transmit power of the UE corresponding weak, this will result in poor call quality becomes the user, since the signal is too weak or even call drop.

[0010] 换句话说,一个NodeB的覆盖区域有限,而随着UE的移动,为了保持通信的连续,UE与网络间的无线连接必须由一个小区转移到另外一个小区,这就是切换。 [0010] In other words, the NodeB a limited coverage area, and with the movement of the UE, in order to maintain a continuous, wireless connections between UE and network communication must be transferred from one cell to another cell, which is switched. 在WCDMA系统中切换包含硬切换、软切换以及系统间切换。 In a WCDMA system handover comprising a hard handover, soft handover and inter-system handover.

[0011] 硬切换是3G系统移动性管理中的一个重要组成部分。 [0011] The hard handover is an important part of the 3G system mobility management. 硬切换是指UE在异频邻区间的切换,这时候UE会先在当前的异频邻区增加链路,新链路建立完成后,便会释放原来的小区中的链路,这样做一方面保持了通话·的连续性,增加了网络的覆盖,同时释放了原来的链路,减少了对无线以及传输资源的占用,异频硬切换是解决无线网络覆盖的重要方法,它包含:在同一个NodeB的两个小区中的异频硬切换;同一个RNC,不同NodeB之间的异频硬切换;不同RNC间的异频硬切换。 Hard handover refers to UE in different frequency range switching neighbor, this time the UE will first increase the link, the new link is established to complete the current inter-frequency neighbor after, it will release the original cell link, do so · maintaining the continuity of the call, increasing the coverage of the network, while freeing the original link, reducing the occupation of radio and transmission resources, inter-frequency hard handover is an important method of wireless network coverage solution, which includes: the NodeB same two cell inter-frequency hard handover; the same RNC, inter-frequency hard handover between different NodeB; inter-frequency hard handoff between different RNC.

[0012] 在硬切换处理的过程中,涉及到了RNC、NodeB以及UE三部分网元,由于存在着一些意外或者不正常的情况导致硬切换处理失败:比如切换的目标小区拥塞、或者目标小区质量太差,由于这种情况的出现,导致切换失败,进而可能会导致掉话。 [0012] During the hard handover process, involving the RNC, NodeB and UE three parts NE, since there are some unexpected or unusual circumstances result in a hard handover process has failed: a target such as handover cell is congested, or a target cell mass too bad, since this happens, the switch fails, which may lead to dropped calls.

[0013] 在无线网络运行的过程中,尤其是建网初期,经常会出现这种问题,同时3GPP的协议对这种TRACE没有相应的协议标准,如何进行协议输出以便于定位硬切换故障问题,在网络运营的过程中会成为一个重点。 [0013] During operation of the wireless network, in particular the initial network construction, which is often the problem, while there is no corresponding protocol 3GPP protocol standards such the TRACE, how to facilitate positioning protocol output hard handover failure problems, in the process of network operations will become a priority.

[0014] 下面介绍几种现有技术中常用的故障分析方法: [0014] The following describes the common fault analysis of several prior art:

[0015] 一、性能统计功能。 [0015] First, the performance statistics.

[0016] 性能统计是通过统计网络中关键的统计项来衡量当前网络的质量,该方法是统计在一个特定的测量周期内硬切换成功/失败次数,并将该统计值反馈给网络管理系统,由网络管理系统进行全面的分析,通过分析结果指导对现有网络的扩容和问题解决。 [0016] The performance statistics are used to measure the quality of the current network key through the network statistics statistical terms, the statistical method is a hard handover success / failure of times within a specified measurement period, and feeds the count value to the network management system, conduct a comprehensive analysis by the NMS, by analyzing the results and guidance on the expansion of existing networks to solve problems.

[0017] 二、全网信令检测方法。 [0017] Second, the whole network signaling detection method.

[0018] 信令跟踪的方法是通过信令跟踪仪器在标准协议接口(如UU,IUB)中跟踪呼叫过程尤其是来自不同网元中的标准协议消息,并将这些相关的消息发送给网络管理中心,通过对这些捕获的消息来进行分析,根据分析结果对网络进行优化,同时解决部分问题。 [0018] A method for tracking signaling by signaling a call tracking instrument track in the standard protocol interfaces (e.g., UU, IUB), especially in people from different message elements in the standard protocol, and send those messages to the associated network management Center, to those captured by news analysis, optimize the network based on the analysis results, while part of the solution.

[0019] 三、告警。 [0019] Third, alarm.

[0020] 网络管理系统对告警信息的处理和分析可以进行网络故障的排除和管理。 [0020] The network management system of the processing and analysis of the alarm information may be a network management and troubleshooting. 在系统发生故障时,告警系统可以实时的将告警产生的原因发送给网络管理系统,网络管理系统可以根据产生告警的原因以及设备来分析并排除所发生的故障。 In the case of system failure, the alarm system can send alerts in real-time to cause the network management system, the network management system can analyze and troubleshoot occurred based on the cause of the alarm and equipment.

[0021] 在实际应用中,上述方案存在以下问题:无法高效查找故障原因。 [0021] In practice, the existence of the program the following issues: Unable to find the efficient cause of the malfunction. 具体的说,对于性能统计功能,性能统计是一种长时间,或者说是一种周期任务的统计功能,在一段时间内统计硬切换成功率或者失败率是多少,这种统计结果本身就很粗糙,并且该功能是统计历史数据,不能对硬切换出现故障的原因进行异常分析。 Specifically, the performance statistics, performance statistics is a long time, or that is one kind of periodic task statistics, statistics over time hard handover success rate or failure rate is the number, which is inherently statistical results rough, and this function is a statistical historical data, not the cause of the hard handoff failure anomaly analysis. 如果提高性能统计的力度,增加对硬切换失败原因的统计,势必会导致大量数据的出现,对正常业务有影响。 If you improve the performance statistics of efforts to increase the statistical reason for the failure of the hard handover, it will inevitably lead to large amounts of data, impact on normal business. 对于全网信令检测方法,这是一种实时的跟踪,需要在所有的接口都要通过特殊的第三方仪器进行跟踪,这种跟踪会产生大量的数据,目前的2G全网信令跟踪只是跟踪了网间的消息,也就是核心网部分的消息,没有跟踪接入网部分。 For the whole network signaling detection method, which is a real-time tracking, need to be tracked through a special third-party instrument interfaces in all, this track will generate a lot of data, the current 2G network-wide signaling tracking only tracking the inter-network message, a message that is part of the core network, access network did not track section. 对于3G系统来说,这些跟踪消息将会是海量的,尤其是如果要跟踪接入网部分的消息。 For 3G systems, these trace messages will be massive, especially if you want to track access network part of the message. 如何从大量的消息跟踪中获取有用的信息,将会是非常大的工作量。 How to obtain useful information from a large number of message tracking, it will be a very large amount of work. 另外通过信令跟踪还需要有很丰富的经验,能够很敏锐的发现消息中存在的问题,这种方法也不便于在维护人员中推广。 Also by signaling tracking also need to have a lot of experience, can very keen to discover problems in the message, this method is not easy to promote the maintenance staff. 对于告警,告警一般来说关注的都是设备故障,对用户故障的关注比较少。 For alarms, alarm devices in general are concerned about the failure, the failure of concern for users is relatively small. 比如用户由于无线原因导致切换出现故障的时候,在告警上是无法体现出来。 Due to reasons such as the user when the wireless switch failure in the alarm is not reflected. 所以告警基本上不能反映或者解决切换出现的问题。 So basically do not reflect the alarm switch or solve the problem arise.

[0064] 通过比较可以发现,本发明的技术方案与现有技术的主要区别在于,当异频硬切换失败或出现故障时,控制切换过程的设备(如RNC)输出指定类型的信息,网管中心(如0MC)据此分析故障原因。 [0064] By comparison found that the main difference between the aspect of the present invention and the prior art is that, when the inter-frequency hard handover failure or malfunction, the control device of the handover process (e.g., RNC) outputting a specified type of information, the network management center (such as 0MC) accordingly analyze the cause. 输出的指定类型的信息包括:消息类型、IMSI、最优小区信息、异频邻区信息、异频硬切换掉话原因、活动集信息、无线接入承载信息、目标小区信息、异频硬切换触发器等;同时还指出了如何利用这些信息进行故障分析。 Specify the type of information output comprises: message type, IMSI, optimal cell information, inter-frequency neighboring cell information, inter-frequency hard handover reason for dropped calls, the active set information, the radio access bearer information, target cell information, inter-frequency hard handover triggers, etc.; also points out how to use this information for fault analysis.

[0065] 这种技术方案上的区别,带来了较为明显的有益效果,即因为指定类型的信息已覆盖了与异频硬切换相关的方方面面,所以可以帮助网管人员有效分析出故障的原因,进而采取相应的改进措施。 [0065] The difference in this solution brings obvious advantageous effect, i.e., because the specified type of information has been covered with the inter-frequency hard handover-related aspects, it is possible to help administrators to effectively analyze the cause of the fault, and then take corresponding measures.

[0066] 因为仅在异频硬切换失败或出现故障时才输出信息,所以对整个移动通信系统增加的额外负担很小,几乎不会对系统的正常业务处理产生影响。 [0066] Since only the inter-frequency hard handover failure or when the output failure information, so that the entire mobile communication system adds additional burden is small, almost no normal business processing system impact occurs.

[0071] 总的来说,本发明的原理在于,当异频硬切换失败或出现故障时,控制切换过程的设备输出指定类型的信息,并根据所述指定类型的信息,更加高效地分析所述异频硬切换故障的原因。 [0071] In general, the principles of the present invention is that, when the inter-frequency hard handover failure or malfunction, the control device outputs information of the specified type handover procedure, and according to the specified type of information, analysis more efficiently said inter-frequency hard handover failure reason. 图3示出根据本发明的一个实施例的异频硬切换故障分析方法的流程。 FIG 3 shows a different embodiment of the present invention frequency hard handover failure flow analysis method.

[0072] 如图所示,首先在步骤310,当UE呼叫建立成功后,RNC将向UE发送测量控制消息,通知UE对异频邻区进行质量测量。 [0072] As shown, first in step 310, a successful call establishment after the UE, the RNC sends a measurement control message to the UE to notify the UE for inter-frequency neighbor cell quality measurement. UE在移动的过程中进行实时测量,当发现有异频邻区的质量满足测量报告触发的条件(详细参见3GPPTS25331)时,UE向RNC发送测量报告(Measurement Report),该消息中包含目标小区的信息。 When the UE performs real-time measurement in the process of moving, and when there inter-frequency quality of a neighboring condition measurement report triggering (see detail 3GPPTS25331) meet, UE sends a measurement report (Measurement Report) to the RNC, the message contains a target cell information.

[0073] 此后,在步骤320,如果RNC根据来自UE的测量报告,如果判定可以切换,则向目标小区所在的NodeB发送无线链路建立请求“Radio Link SetupRequest”消息。 [0073] Thereafter, at step 320, if the RNC according to the measurement report from the UE, if it is determined to switch, to the target cell where the NodeB sends a radio link setup request "Radio Link SetupRequest" message.

[0074] 接着,在步骤330,NodeB收到来自RNC的请求消息后,随即向RNC反馈无线链路建立响应“Radio Link Setup Response”消息,通知RNC无线链路建立完成。 After [0074] Next, at step 330, NodeB receives the request message from the RNC, then the RNC to establish a radio link feedback in response to "Radio Link Setup Response" message, RNC notifies the radio link setup is completed.

[0075] 在步骤340,RNC收到NodeB的成功响应后,开始建立ALCAP传输层部分。 [0075] In step 340, the RNC receives a successful response NodeB, the transmission start building ALCAP layer portion. 参见图中的ALCAP Iub 数据传输承载建立(ALCAP Iub Data TransportBearer Setup)。 ALCAP Iub data transport bearer setup see Figure (ALCAP Iub Data TransportBearer Setup).

[0076] 在步骤350,传输层建立完成后,RNC向UE发送DDCH :物理信道重配置“DCCH :Physical Channel Reconfiguration”消息,通知UE修改相应的参数,以便接收来自另外一个小区的信息。 [0076] Once created, at step 350, the transport layer, the RNC transmits to the UE DDCH: a physical channel reconfiguration "DCCH: Physical Channel Reconfiguration" message to notify the UE modifying the corresponding parameters in order to receive a further message from the cell.

[0077] 此后,在步骤360,这时由于UE移动到来目标NodeB下面的小区,源NodeB向RNC发送无线链路失败指示(Radio Link Failure Indication),通知RNC该UE已经同NodeB失步。 [0077] Thereafter, in step 360, the arrival time due to the movement of the target UE NodeB following cell, the source NodeB transmits a radio link failure indication to the RNC (Radio Link Failure Indication), informs the RNC that the UE has been out of synchronization with the NodeB.

[0078] 接着,在步骤370,目标NodeB发送无线链路恢复指示“Radio LinkRestoreIndicator”消息通知RNC,UE目前在目标NodeB已经无线链路恢复。 [0078] Next, at step 370, the target NodeB transmits a radio link restore indication "Radio LinkRestoreIndicator" message to notify RNC, UE currently in the target NodeB has a radio link recovery.

[0079] 在步骤380,此时UE向RNC发送DCCH :物理信道重配置完成“DCCH physicalChannel Reconfiguration Complete”消息,告知RNC物理信道重配置已经完成,可以在新的链路上发送数据。 [0079] In step 380, when the UE sends the RNC DCCH: Physical Channel Reconfiguration Complete "DCCH physicalChannel Reconfiguration Complete" message informs the RNC of the physical channel reconfiguration has been completed, data can be sent on the new link.

[0080] 然后,在步骤390, RNC向源NodeB发送无线链路删除请求“Radio LinkdeletionRequest”消息,释放上面的无线链路。 [0080] Then, in step 390, RNC to the source NodeB transmits a radio link deletion request "Radio LinkdeletionRequest" message, to release the radio link above.

[0081] 最后,源NodeB向RNC发送无线链路建立响应“Radio Link DeletionResponse”消息。 [0081] Finally, the source NodeB transmits to the RNC a radio link setup response "Radio Link DeletionResponse" message.

[0082] 在上述步骤中,都可能出现硬切换失败。 [0082] In the above steps, both the hard handoff failure may occur. 举例来说,当RNC发现目标小区拥塞,那么就不会向NodeB发送无线链路建立请求“Radio Link SetupRequest”消息,从而导致切换过程失败,如果发生硬切换失败,则RNC向诸如操作维护中心(Operations&MaintenanceCenter,简称“0MC”之类的网络管理中心发送相关的消息,其中包含指定类型的信息。OMC的网管人员通过对这些信息的分析,可以知道硬切换失败原因,并采取相应的措施。 For example, when the target cell is congested RNC found, it will not be sent to the NodeB radio link setup request "Radio Link SetupRequest" message, resulting in failure of the handover process, if the hard handover failure occurs, such as the RNC to the Operation and Maintenance Center ( Operations & MaintenanceCenter, network management center referred to "0MC" like sending relevant message containing network administrators to specify the type of information .OMC through the analysis of this information, you can know the hard handover causes of failure and take appropriate measures.

[0083] 下面将通过表I〜表19,对上述“指定类型的信息”,以及这些信息的分析方法进行说明。 The [0083] Table 19 below, by I~ table, the above-described "specify the type of information", the information and the analysis method will be described. 其中,黑体字部分是信息元素分组的组名,非黑体字的是信元。 Wherein, the group name is boldface packet information elements, the cell is non-bold.

[0121] 根据上述说明,如果用户正在进行CS12.2K语音通话,当移动到小区边缘的时候进行异频硬切换,但是失败。 [0121] According to the above description, if the user is making a voice call CS12.2K, when moved to the edge of the cell inter-frequency hard handover, but failed. 可以通过用户的手机号码,也就是MSISDN,根据MSISDN查找到该用户手机的MSI。 Yes, that is MSISDN, find the user's mobile phone via MSI user's mobile phone number based on MSISDN. 或者通过小区进行搜索,生成如下表格: Or search through the cell, generate the following table:

[0122] [0122]

[0123] 通过对上述表格中内容的分析,可以获得如下信息:一、目前用户已经移动到小区101和120的共同覆盖区,此时最好小区101的质量已经比较差了,而UE检测到小区120的小区已经满足了异频硬切换2D的门限,从而UE报了2D事件。 [0123] By analyzing the contents of the above table, the following information can be obtained: First, the current user has moved to a cell coverage area 101 and 120 together, in which case the quality of the best cell 101 has a relatively poor, and the UE detects cell cell 120 has met inter-frequency hard handover threshold 2D, 2D so that the UE reported events. 二、RNC判断出该120号小区满足异频硬切换条件后,触发了异频硬切换,但是由于120号小区当前的负载已经非常高了。 Two, the RNC 120 determines that the number of inter-frequency cell satisfies the condition of hard handover, triggers the inter-frequency hard handover, but since the number of current load cell 120 is already very high. 其中TCP达到了90%,超过了接入该小区的门限,从而导致异频硬切换在120小区失败。 Wherein the TCP reached 90%, exceeding the threshold of the cell access, resulting in inter-frequency hard handover failure in 120 cells.

[0124] 从上面的输出参数可以知道,本次异频硬切换失败的原因是因为目标小区已经负载很重,导致准入失败而引起的切换失败,由此可以得出以下分析结果:第一,目标小区是否处于热点的中心位置。 [0124] The above can be known from the output parameter, in this inter-frequency hard handover failure reason is because the target cell has heavy load, leading to failure due to access handover failure, the following results can be concluded: a first , the target cell is in the center position of the hot spot. 如果是,那么应当优化网络,减少将该目标小区作为邻区;第二,目标小区的导频功率是否设置太大了,导致太多用户接入到该小区中。 If so, the network should be optimized to reduce the target cell as neighbor; second, the target cell pilot power is set too high, resulting in too many users access to the cell. 如果是,那么应当减小功率,以便使得用户可以平均分布到其它相邻小区;第三,修改目标小区的小区选择与重选参数,以便使得在该小区中的用户在空闲的时候更容易重选到其它邻区;第四,是否应当修改到目标小区的异频硬切换启动门限,减少到目标小区的切换。 If so, the power should be decreased, so that the user can be evenly distributed to the other adjacent cells; third, modify the target cell selection and cell reselection parameters, so that the user is in the cell free time easier weight is selected from the neighboring other; fourth, whether the cell should be modified to target inter-frequency hard handover start threshold, to reduce the handover target cell.

[0125] 下面再举出一个硬切换失败原因分析例子。 [0125] The following further include a hard handoff failure cause analysis example. 该例子仍然采用上述情况,但是用户只有一个PS384K的业务,异频硬切换故障输出表格如下: To continue with the example situation, but only a user traffic PS384K, inter-frequency hard handover failure output the following table:

[0126] [0126]

[0127] 从异频硬切换失败的输出可以获取以下信息:一、该用户接收到的信号质量已经非常差了,需要进行切换以便继续满足通话的要求,否则就会掉话;二、异频硬切换的目标小区是RNC 10的120号小区,该小区的质量是很好的,可以异频硬切换到该小区,另外除了这个小区后,没有其它邻区质量比较好;三、RNC触发了异频硬切换后,发现IUB接口的传输带宽不能满足384K业务所需带宽,那么本次异频硬切换失败。 [0127] Output from the hard inter-frequency handover failure can obtain the following information: First, the user has the received signal quality is poor, handover is required to continue to meet the requirements of the call, otherwise dropped calls; Second, inter-frequency hard handover target cell is the 120 cell RNC 10, the cell quality is good, can be inter-frequency hard handover to the cell, the cell after further addition, no other neighbor is better quality; Third, the RNC triggers after the inter-frequency hard handover, found IUB interface bandwidth can not satisfy the required bandwidth traffic 384K, then this inter-frequency hard handover failure.

[0128] 从上面的信息我们可以知道,当前的IUB接口资源已经不足,无法在IUB接口建立无线链路,从而导致了异频硬切换失败。 [0128] From the above information we can know the current IUB interface resources have been insufficient to establish a wireless link IUB interfaces, leading to inter-frequency hard handover failure. 由此,通过上述输出,可以得出如下分析结果••第一,384K的PS业务占用的传输信道带宽资源大概是570k byte左右,对于PS业务的切换应当尽量将这些用户切换到负载较轻的NodeB上。 Thus, by the output, the following results can be derived •• a first, 384K PS service transmission channel bandwidth occupied resource is probably about 570k byte, for the PS service handover should try to switch the user to load these lighter NodeB on. 比如在网络规划的时候,可以将这些PS用户较集中的NodeB上的小区多配置一些负载较轻的小区作为邻区,以便这些用户在移动的过程中能够成功的异频硬切换到其它小区。 For example when the network planning, the cell can be a higher concentration of these PS NodeB multiple users to configure some lighter load cell as a neighbor, so that those different users on the move can be successfully frequency hard handover to another cell. 第二,检查IUB接口带宽,是否该带宽配置不合适,因为在建网初期可能由于用户不多,那么传输带宽一般都比较小,但是随着用户的增多,那么用户业务量就会相应的增加,所以就应当根据实际情况增加IUB接口的带宽,以满足用户需求。 Second, check the IUB interface bandwidth, whether the bandwidth configuration is not appropriate, because users may be due to much, then the transmission bandwidth are generally small, but with the increase of users, then the user will be a corresponding increase in business volume in the initial network construction , so that IUB interface bandwidth should be increased according to the actual situation, in order to meet user needs.

[0129] 通过对上述内容的分析,可以理解,本发明为了可以高效地分析异频硬切换的故障原因,在异频硬切换失败或出现故障时,控制切换过程的设备输出指定类型的信息,网管中心据此分析故障原因。 [0129] Through the analysis of the above, it is understood, the present invention in order to analyze the fault reason for inter-frequency hard handover efficiently, the inter-frequency hard handover failure or malfunction occurs, the control device outputs the specified type of information of the handover procedure, NMC accordingly analyze the cause. 输出的指定类型的信息包括:消息类型、IMSI、最优小区信息、异频邻区信息、异频硬切换掉话原因、活动集信息、无线接入承载信息、目标小区信息、异频硬切换触发器等;同时还指出了如何利用这些信息进行故障分析。 Specify the type of information output comprises: message type, IMSI, optimal cell information, inter-frequency neighboring cell information, inter-frequency hard handover reason for dropped calls, the active set information, the radio access bearer information, target cell information, inter-frequency hard handover triggers, etc.; also points out how to use this information for fault analysis. 由于指定类型的信息覆盖了与异频硬切换相关的方方面面,所以可以帮助网管人员有效分析出故障的原因,进而采取相应的改进措施。 Since the type of information specified cover and inter-frequency hard handover-related aspects, it is possible to help administrators to effectively analyze the cause of the failure, and then take corresponding measures. 此外,本发明仅在异频硬切换失败或出现故障时才输出信息,所以对整个移动通信系统增加的额外负担很小,几乎不会对系统的正常业务处理产生负面影响。 Further, in the present invention is only inter-frequency hard handover or failure information output when a failure occurs, so that the entire mobile communication system adds an additional burden is small, almost does not adversely affect the normal operations of the processing system.
