一种长期演进无线网络全网跟踪的方法、装置及系统A method, device and system for network-wide tracking of long-term evolution wireless networks

技术领域technical field

本发明涉及无线通信技术领域，尤其涉及一种LTE(Long Term Evolution，长期演进)无线网络全网跟踪的方法、装置及系统。The present invention relates to the technical field of wireless communication, in particular to a method, device and system for whole-network tracking of an LTE (Long Term Evolution, Long Term Evolution) wireless network.

背景技术Background technique

全网跟踪是无线网络测试、网络监视、问题发现与定位、网络评估的重要手段。目前LTE无线网络跟踪的方法主要有基于IMSI(International MobileSubscriber Identification Number，国际移动用户识别码)的跟踪和基于小区的跟踪。下面分别介绍现有的基于IMSI的跟踪和基于小区的跟踪。Network-wide tracking is an important means for wireless network testing, network monitoring, problem discovery and location, and network evaluation. At present, the methods of LTE wireless network tracking mainly include tracking based on IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number) and tracking based on cells. The existing IMSI-based tracking and cell-based tracking are introduced respectively below.

现有的基于IMSI的跟踪流程如下：The existing IMSI-based tracking process is as follows:

1)跟踪后台向MME(Mobility Management Entity，移动性管理实体)发送指定IMSI的跟踪激活消息，跟踪激活消息中包括跟踪标识Trace id、跟踪深度、跟踪级别等参数；1) The tracking background sends a tracking activation message of the specified IMSI to the MME (Mobility Management Entity, Mobility Management Entity), and the tracking activation message includes parameters such as the tracking identifier Trace id, tracking depth, and tracking level;

2)MME判断对应的UE(User Equipment，用户设备)的偶联是否存在，若存在，进入3)，若不存在，进入4)；2) The MME judges whether the coupling of the corresponding UE (User Equipment, user equipment) exists, if it exists, enter 3), if it does not exist, enter 4);

3)MME下发Trace Start消息给eNB(evolved Node B，演进型基站)，进入5)；3) MME sends a Trace Start message to eNB (evolved Node B, evolved base station), enter 5);

4)在该UE的S1偶联建成后，将跟踪配置立即下发，转5)，遵循原则：4) After the S1 coupling of the UE is completed, the tracking configuration will be issued immediately, and then go to 5), following the principle:

-要尽可能早的下发Trace配置；- Trace configuration should be delivered as early as possible;

-若当前下发的S1口消息可以携带跟踪信元，则携带在该消息中下发；- If the S1 port message sent currently can carry tracking cells, carry them in the message and send them;

-若当前下发的S1口消息不可以携带跟踪信元，则通过Trace Start消息下发；- If the S1 port message sent currently cannot carry trace cells, it will be sent through the Trace Start message;

5)eNB收到Trace Start消息后，激活该UE的指定IMSI跟踪；5) After receiving the Trace Start message, the eNB activates the specified IMSI tracking of the UE;

6)跟踪任务结束，跟踪后台向MME发送去激活该IMSI的跟踪；6) When the tracking task ends, the tracking background sends a tracking message to the MME to deactivate the IMSI;

7)MME收到去激活消息，立即向eNB发送Deactive Trace消息；7) The MME immediately sends a Deactive Trace message to the eNB after receiving the deactivation message;

8)eNB收到Deactive Trace消息后，停止对该UE指定的IMSI跟踪；8) After receiving the Deactive Trace message, the eNB stops tracking the IMSI specified by the UE;

可携带跟踪信元的S1口消息包括：Initial Context Setup Req、HandoverRequest和Trace Start消息。S1 port messages that can carry trace cells include: Initial Context Setup Req, HandoverRequest, and Trace Start messages.

从上述流程可以看出，基于指定IMSI的跟踪，在UE切换后继续保持相关指定IMSI的跟踪任务信息，保持相关跟踪任务信息的方式如下：It can be seen from the above process that based on the tracking of the specified IMSI, the tracking task information of the relevant specified IMSI will continue to be maintained after the UE is handed over, and the way of maintaining the relevant tracking task information is as follows:

1)若UE为X2口切换，将该UE在源侧激活的Trace跟踪配置信息(包括Trace id，跟踪深度，跟踪级别等参数)携带在X2口的Handover Request消息中，携带至目的eNB，用于目的eNB开启此UE的指定IMSI跟踪；1) If the UE is switched to the X2 port, the Trace tracking configuration information (including parameters such as Trace id, trace depth, and trace level) activated by the UE on the source side is carried in the Handover Request message of the X2 port, and carried to the target eNB. Enable the specified IMSI tracking of the UE in the target eNB;

2)若UE为S1口切换，跟踪任务相关信息由MME来保证，MME需将该UE在源eNB的跟踪配置信息携带在S1的Handover Request消息中，携带至目的eNB，用于目的eNB开启此UE的指定IMSI跟踪。2) If the UE is handed over to the S1 port, the tracking task-related information is guaranteed by the MME, and the MME needs to carry the tracking configuration information of the UE in the source eNB in the Handover Request message of S1, and carry it to the target eNB for the target eNB to open this UE's specified IMSI tracking.

现有的基于小区的跟踪流程包括以下步骤：The existing cell-based tracking process includes the following steps:

1)跟踪后台向eNB发送小区跟踪激活消息激活小区跟踪；1) The tracking background sends a cell tracking activation message to the eNB to activate cell tracking;

2)eNB收到小区跟踪激活消息后，对于已存在的UE和新接入的UE(包括切入小区的UE)生成跟踪标识Trace id，并立即组装小区流量跟踪CellTraffic Trace消息发送给MME；2) After the eNB receives the cell tracking activation message, it generates a tracking identifier Trace id for the existing UE and the newly accessed UE (including the UE that has switched into the cell), and immediately assembles the cell traffic tracking CellTraffic Trace message and sends it to the MME;

3)MME上报Trace id与IMSI的关系到跟踪后台；3) MME reports the relationship between Trace id and IMSI to the tracking background;

4)跟踪任务结束，跟踪后台向eNB发送小区去激活消息，eNB停止对小区的跟踪。4) After the tracking task ends, the tracking background sends a cell deactivation message to the eNB, and the eNB stops tracking the cell.

从上述流程可以看出，基于小区的跟踪，在UE切换出激活小区后不保持在原小区的相关跟踪任务信息。It can be seen from the above process that the cell-based tracking does not keep the relevant tracking task information in the original cell after the UE switches out of the activated cell.

然而，异常跟踪、测量报告和用户话单详细信息跟踪通常都是基于小区级别或者全网跟踪的，由于现有的基于小区的跟踪在UE切换出跟踪激活小区后不保持在原小区的相关跟踪任务信息，并且切换后不能将源侧eNB跟踪配置信息(主要是跟踪标识Trace id)携带到目标eNB，导致后续关联和分析一次通话的话单信息、及分析哪次通话出现异常以及此次通话话单异常信令信息十分困难。However, abnormality tracking, measurement reports, and detailed information tracking of user bills are usually based on cell-level or network-wide tracking, because the existing cell-based tracking does not maintain the relevant tracking tasks in the original cell after the UE switches out of the tracking active cell information, and the tracking configuration information (mainly the tracking identifier Trace id) of the source side eNB cannot be carried to the target eNB after switching, resulting in subsequent association and analysis of the bill information of a call, and analysis of which call is abnormal and the bill of this call Exception signaling information is difficult.

因此，亟待提供一种改进的LTE无线网络全网跟踪的方法、装置及系统以克服上述缺陷。Therefore, it is urgent to provide an improved method, device and system for network-wide tracking of an LTE wireless network to overcome the above-mentioned defects.

下面结合图1对本发明的蓄电池工作状态的指示方法的实施例进行说明。An embodiment of the method for indicating the working state of the storage battery of the present invention will be described below with reference to FIG. 1 .

图1为本发明LTE无线网络全网跟踪的方法的一个实施例的流程示意图。本实施例的LTE无线网络全网跟踪的方法包括：FIG. 1 is a schematic flowchart of an embodiment of a method for network-wide tracking of an LTE wireless network according to the present invention. The method for the whole network tracking of the LTE wireless network of the present embodiment includes:

步骤S101：跟踪后台向一个或多个eNB发送小区跟踪激活消息，所述小区跟踪激活消息中包括跟踪配置信息，如跟踪深度、跟踪级别、数据上报IP地址等。所述小区跟踪激活消息可以分为小区异常跟踪、小区详细跟踪、测量报告跟踪激活消息等。具体的，所述跟踪后台可以是网管，也可以是独立的跟踪工具。所述跟踪深度是指跟踪过程中将根据具体需要设置不同跟踪深度，网元根据跟踪深度的要求上报跟踪消息的IE项范围。所述跟踪级别是指：为了既满足跟踪使用的需要又能够尽量降低跟踪消息量，根据应用场景不同，对用户跟踪、小区跟踪所牵涉消息的范围进行分级。其包括基本级、切换级、详细级、调试级4种。其中，基本级：跟踪用户的UU、X2、S1接口呼叫相关、测量相关的无线网络层消息(包括位置测量)；详细级：除基本级范围外，还包括传输网络层消息；调试级：除切换级范围外，还包括设备内部子系统间用户相关的消息，用于研发人员调试和定位问题，对外部用户不可见。Step S101: The tracking background sends a cell tracking activation message to one or more eNBs, and the cell tracking activation message includes tracking configuration information, such as tracking depth, tracking level, and data reporting IP address. The cell tracking activation message may be divided into cell abnormal tracking, cell detailed tracking, measurement report tracking activation messages, and the like. Specifically, the tracking background can be a network administrator, or an independent tracking tool. The tracking depth refers to the range of IE items in which different tracking depths will be set according to specific needs during the tracking process, and the network elements will report tracking messages according to the requirements of the tracking depth. The tracking level refers to grading the scope of messages involved in user tracking and cell tracking according to different application scenarios in order to meet the needs of tracking and reduce the amount of tracking messages as much as possible. It includes four types: basic level, switching level, detailed level, and debugging level. Among them, the basic level: track the user's UU, X2, S1 interface call-related and measurement-related wireless network layer messages (including location measurement); detailed level: in addition to the scope of the basic level, it also includes transmission network layer messages; debugging level: except Outside the scope of the switching level, it also includes user-related messages between internal subsystems of the device, which are used by developers to debug and locate problems, and are invisible to external users.

步骤S102：eNB收到小区跟踪激活消息后，为小区中的已存在的和新接入的UE生成新的跟踪标识Trace id，同时生成跟踪消息，所述跟踪消息携带所述新生成的跟踪标识Trace id并记录了所述跟踪标识Trace id的生成原因和时间。具体的，所述跟踪标识Trace id是全网唯一的，由所述跟踪标识Trace id生成时的时间、所述用户设备所在的基站标识和所述用户设备的标识组成，共64bit，具体生成方式如下：Trace id＝小时(5bit)+分钟(6bit)+秒(6bit)+毫秒(10bit)+eNB_id(20bit)+UE_Gid(16bit)。Step S102: After receiving the cell tracking activation message, the eNB generates a new trace ID for existing and newly accessed UEs in the cell, and generates a trace message at the same time, and the trace message carries the newly generated trace ID Trace id and recorded the generation reason and time of said tracking identification Trace id. Specifically, the trace ID Trace id is unique in the entire network, and is composed of the time when the trace ID Trace id is generated, the base station identifier where the user equipment is located, and the identifier of the user equipment, a total of 64 bits, and the specific generation method As follows: Trace id = hour (5bit) + minute (6bit) + second (6bit) + millisecond (10bit) + eNB_id (20bit) + UE_Gid (16bit).

步骤S103：根据切换方式确定新切入的UE的跟踪标识Trace id，对于生成了新的跟踪标识Trace id的UE，同时生成相应的跟踪消息，所述跟踪消息携带所述新生成的跟踪标识Trace id并记录了所述跟踪标识Trace id的生成原因和时间。Step S103: Determine the Trace id of the newly cut-in UE according to the handover method, and generate a corresponding trace message for the UE that has generated a new Trace id, and the trace message carries the newly generated Trace id And record the generation reason and time of described tracking mark Trace id.

进一步地，若所述新切入的UE基于X2口切换，在这种情况下，若所述新切入的UE的指定IMSI跟踪和小区跟踪同时开启，那么源侧eNB在HandoverRequest消息中携带的是指定IMSI跟踪的Trace id和相关跟踪配置信息，而不能携带源侧小区跟踪的Trace id；目标侧eNB为此切换的UE生成新的跟踪标识Trace id，同时生成相应的跟踪消息以记录所述跟踪标识Trace id是由于X2口切换所致并记录所述跟踪消息的生成时间。Further, if the newly switched-in UE is handover based on the X2 interface, in this case, if the specified IMSI tracking and cell tracking of the newly switched-in UE are enabled at the same time, then the source side eNB carries the specified IMSI tracking and cell tracking in the HandoverRequest message The Trace id and related tracking configuration information tracked by the IMSI cannot carry the Trace id tracked by the source cell; the target eNB generates a new Trace ID for the handed over UE, and generates a corresponding trace message to record the Trace ID Trace id is due to X2 interface switching and records the generation time of the trace message.

若该新切入的UE没有指定IMSI跟踪，则源侧eNB在Handover Request消息中携带在源侧eNB激活的跟踪标识Trace id和所述跟踪配置信息，那么目标侧eNB检测X2口Handover Request消息中携带的Trace id和相关跟踪配置信息，以确定所述新切入的用户设备的跟踪标识Trace id，并激活此UE的小区跟踪。If the newly cut-in UE does not specify IMSI tracking, the source side eNB carries the trace identifier Trace id activated by the source side eNB and the tracking configuration information in the Handover Request message, and the target side eNB detects that the X2 port Handover Request message carries Trace id and related trace configuration information to determine the trace identifier Trace id of the newly switched-in user equipment, and activate the cell trace of this UE.

若所述新切入的UE基于S1口切换，则eNB为所述UE生成新的跟踪标识Trace id，以激活此UE的小区跟踪；同时生成相应的跟踪消息以记录所述跟踪标识Trace id是由于S1口切换所致并记录所述跟踪消息的生成时间。If the newly switched-in UE is handed over based on the S1 port, the eNB generates a new tracking identifier Trace id for the UE to activate cell tracking of the UE; at the same time, generates a corresponding tracking message to record that the tracking identifier Trace id is due to It is caused by the switching of the S1 port and records the generation time of the trace message.

步骤S104：将所述跟踪消息发送给所述跟踪后台。Step S104: Send the tracking message to the tracking background.

步骤S105：eNB组装小区流量跟踪Cell Traffic Trace消息，并将所述小区流量跟踪Cell Traffic Trace消息发送给MME，所述小区流量跟踪Cell TrafficTrace消息携带所述跟踪标识Trace id。Step S105: The eNB assembles a Cell Traffic Trace message, and sends the Cell Traffic Trace message to the MME, and the Cell Traffic Trace message carries the trace identifier Trace id.

步骤S106：所述跟踪后台收到MME上报的跟踪标识Trace id与国际移动用户识别码IMSI的关系。Step S106: The tracking background receives the relationship between the tracking identifier Trace id and the International Mobile Subscriber Identity IMSI reported by the MME.

步骤S107：eNB将跟踪结果数据发送给所述跟踪后台。具体的，eNB将需要的跟踪信令和信息等数据进行缓存，当UE掉话、切出或者缓冲区满，则经过流控将缓存的数据发送到所述跟踪后台。Step S107: the eNB sends the tracking result data to the tracking background. Specifically, the eNB caches data such as tracking signaling and information required, and when the UE drops calls, switches out, or the buffer is full, the buffered data is sent to the tracking background through flow control.

前述步骤S105～S107为本领域技术人员熟知，故在此省略详细描述。The aforementioned steps S105-S107 are well known to those skilled in the art, so detailed descriptions are omitted here.

由于本实施例的LTE无线网络全网跟踪的方法在UE切换后，目标eNB接收源侧eNB的UE的Trace id，为UE生成新的Trace id并生成跟踪消息以记录新的Trace id的生成原因和时间，然后将该跟踪消息发送给跟踪后台，从而所述跟踪后台可以根据跟踪结果、Trace id与IMSI的关系、以及Trace id生成的原因和时间，进行话单关联分析。采用本实施例的LTE无线网络全网跟踪的方法可以很容易区分一次通话过程中的相关信息，大大提高网络问题发现与定位、用户投诉解决，优化分析的效率。Since the method for tracking the entire network of the LTE wireless network in this embodiment is after the UE is handed over, the target eNB receives the Trace id of the UE of the source eNB, generates a new Trace id for the UE, and generates a trace message to record the reason for the generation of the new Trace id and time, and then the tracking message is sent to the tracking background, so that the tracking background can perform bill correlation analysis according to the tracking result, the relationship between the Trace id and the IMSI, and the reason and time that the Trace id generates. The method for tracking the whole network of the LTE wireless network of this embodiment can easily distinguish relevant information during a call, greatly improving the efficiency of network problem discovery and location, user complaint resolution, and optimization analysis.
