Technical field

本发明实施例涉及通信技术领域， 尤其涉及一种检测盲区的方 法、 ***及设备。 背景技术  The embodiments of the present invention relate to the field of communications technologies, and in particular, to a method, system, and device for detecting a blind zone. Background technique

在网络运行当中，经常会出现如基站硬件故障、传输中断等问题， 这些问题可以通过网络操作维护设备来发现， 找到解决方法。但是某 些没有导致严重掉话的上下行干扰、覆盖不合理等问题， 在统计中难 以被发现，而这些问题又是与用户联系最紧密、最直接的问题，对此， 应根据采集到的数据，通过分析网络运行过程中出现的问题做出准确 的判断， 同时依据测试结果， 对问题的改进或优化提出调整方案。 在 现有技术中， 可以通过路测设备实现上述功能。  In the network operation, problems such as base station hardware failure and transmission interruption often occur. These problems can be discovered through network operation and maintenance equipment, and solutions can be found. However, some problems such as uplink and downlink interference and unreasonable coverage that cause serious dropped calls are difficult to be found in statistics, and these problems are the closest and most direct problems to users. Data, make an accurate judgment by analyzing the problems that occur during the operation of the network, and at the same time, based on the test results, propose an adjustment plan for the improvement or optimization of the problem. In the prior art, the above functions can be realized by a drive test device.

路测设备是为网络优化、 规划工作而专门生产的软、 硬件设备， 其中包括数据采集前端、 GPS ( Global Positioning System, 全球定位 *** )及专用测试软件等。 目前的数据采集前端多为内部有特殊软件 的测试手机， 可以依靠网络完成一些特殊功能， 如锁频、 强制切换、 显示网络信息、确定网络盲区等；也可以不依靠网络来完成一些功能， 如全频段扫频和选频点扫频等； 同时还可以通过计算机与手机之间的 通信电缆接收计算机发来的指令，并且将采集到的数据传输给计算机 存储起来， 供计算机进一步处理。  The road test equipment is a software and hardware device specially produced for network optimization and planning work, including data acquisition front end, GPS (Global Positioning System) and special test software. The current data acquisition front-end is mostly a test mobile phone with special software inside. It can rely on the network to complete some special functions, such as frequency lock, forced switching, display network information, determine network blind zone, etc., or can complete some functions without relying on the network, such as Full-band frequency sweeping and frequency-selection point sweeping; etc.; At the same time, the computer can also receive the instructions sent by the computer through the communication cable between the computer and the mobile phone, and transmit the collected data to the computer for storage for further processing by the computer.

然而，采用路测方式检测盲区是需要人为干预的，费用较为昂贵， 成本高， 不符合运营商对网络费用成本的需求。 另外， 等到进行路测 时往往掉话现象已经较为严重， 并且已经给用户造成很大的影响， 不 能及时解决覆盖问题。 更进一步讲， 不是所有的地方都适合用路测的 方法， 因此路测方式受到一定的地域局限。 However, the use of road test to detect blind spots requires human intervention, which is expensive and costly, and does not meet the operator's demand for network cost. In addition, when the road test is performed, the call drop phenomenon is already serious, and it has already had a great impact on the user. Can solve the coverage problem in time. Furthermore, not all places are suitable for road test methods, so the way of road test is limited by certain geographical areas.

针对路测技术存在的上述问题，现有技术提出了另一种盲区检测 方法， 由 MS ( Mobile Station, 移动台）上报测量信息； 或在激活状 态下， 无需 MS提供测量信息， 而由网络记录终端的行踪， 对特殊状 态的信息进行搜集， 其中的特殊状态包括： 小区失去覆盖； 或重选小 区； 或在空闲状态下发起业务并发现失去覆盖。  For the above problems of the road test technology, the prior art proposes another blind zone detection method, which reports the measurement information by the MS (Mobile Station); or in the activated state, the MS does not need to provide measurement information, but is recorded by the network. The location of the terminal collects information of a special state, wherein the special state includes: the cell loses coverage; or reselects the cell; or initiates a service in an idle state and finds that the coverage is lost.

在实现本发明的过程中， 发明人发现现有技术至少存在以下问 题：  In carrying out the process of the present invention, the inventors have found that the prior art has at least the following problems:

此现有技术方案虽然提供了覆盖区域的检测报告，但是接收上报 信息的上报小区不会对上报信息进行选择性的接收，现有技术方案没 有考虑到上报小区当时的负载状况或上报小区重复接收来自不同终 端的相同或相似上报信息导致的积累情况，结果会影响上报小区中其 他用户业务的开展， 严重的可能会造成上报小区瘫痪等不良后果。 发明内容  Although the prior art solution provides the detection report of the coverage area, the reporting cell that receives the report information does not selectively receive the report information, and the prior art solution does not consider the load status of the reporting cell or the repeated reception of the reporting cell. The accumulation of the same or similar reported information from different terminals may result in the development of other users in the reporting cell, which may result in adverse consequences such as reporting cell defects. Summary of the invention

下面结合附图和实施例，对本发明的具体实施方式作进一步详细 描述：  The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.

本发明实施例提供了一种 SON ( Self-Organization Network, 自组 织网络）中 MS辅助检测盲区的方法。 其中盲区指用户无法与网络进 行通信的区域， 包括可以收到网络信息而无法上 信息的区域和无法 接收网络信息并且无法上报信息的区域。  An embodiment of the present invention provides a method for assisting detection of a blind zone in an SON (Self-Organization Network). The blind zone refers to the area where the user cannot communicate with the network, including the area where the network information can be received but the information cannot be received, and the area where the network information cannot be received and the information cannot be reported.

其中， SON 主要包括基站的规划、 搭建、 配置和升级过程中的 自动管理、 配置以及优化过程， 同时也可能包括网络中网元状态变化 引起的自动管理、 配置以及优化过程， 例如当网管告警产生时， 网络 需要能够完成自动侦测、 判断并修复等功能。 The SON mainly includes the automatic management, configuration, and optimization process during the planning, setup, configuration, and upgrade of the base station, and may also include changes in the network state of the network. The automatic management, configuration, and optimization process, for example, when the network management alarm is generated, the network needs to be able to perform automatic detection, judgment, and repair functions.

对于干扰情况， 网络中对干扰分类的依据参数分别是 RSSI ( Receive Signal Strength Indicator,接收信号强度指示）、 SNR( Signal Noise Ratio ,信噪比 )、 I( Interference,干扰 )、 INR( Interference-to-Noise Ratio, 干扰噪声比） ， 具体如下：  For the interference situation, the parameters for classifying the interference in the network are RSSI (Received Signal Strength Indicator), SNR (Signal Noise Ratio), I (Interference), and INR (Interference-to). -Noise Ratio, interference noise ratio, as follows:

首先， 各个相关的参数所确定门限值如下： First, the thresholds determined by each relevant parameter are as follows:

[SNR匪] =S;  [SNR匪] = S;

[Imargin]一工，  [Imargin] A job,

[賺匪 ]=log₁₀10，0)-l=N; [Make money]=log ₁₀ 10,0)-l=N;

其中， RSSI为接收信号强度指示； SNR为信噪比； INR为干扰 噪声比； I为干扰。  Wherein, RSSI is the received signal strength indication; SNR is the signal to noise ratio; INR is the interference to noise ratio; and I is the interference.

将干扰分类如下：  Classify the interference as follows:

可以接受的干扰条件：  Acceptable interference conditions:

RSSI>R, SNR>S, INR < N;  RSSI>R, SNR>S, INR < N;

有害干扰条件：  Harmful interference conditions:

RSSI>R, SNR>S, INR > N;  RSSI>R, SNR>S, INR > N;

变性干扰条件：  Denatured interference conditions:

RSSI>R, SNR<S, INR>N。  RSSI>R, SNR<S, INR>N.

根据不同的干扰条件， 在处理上也存在差异。 比如， 对于可以接 受的干扰， 不需要进行调整还可以继续通信； 对于有害干扰， 用户虽 然可以通信， 但是存在随时会被干扰导致通信中断的风险， 对此可以 通过某种技术来标识有害干扰源，并且通过协调机制保证网络信号不 受干扰； 对于变性的干扰， 用户已经无法与网络进行通信， 但是还可 以接收相关的信息， 此时若没有办法消除干扰， 用户就会因干扰而中 断通信。  There are also differences in processing depending on the interference conditions. For example, for acceptable interference, communication can be continued without adjustment; for harmful interference, users can communicate, but there is a risk that communication will be interrupted at any time, and a certain technology can be used to identify harmful interference sources. And through the coordination mechanism to ensure that the network signal is not interfered; for degraded interference, the user has been unable to communicate with the network, but can also receive relevant information, and if there is no way to eliminate the interference, the user will interrupt the communication due to interference.

上述盲区的判断依据和相关信息如下：  The judgment basis and related information of the above blind area are as follows:

RSSI>R, SNR<S, INR>N (带信号盲区， 即变性的干扰）或 RSSI < R, SNR < S, INR > N (无信号盲区） 。 本发明实施例主要针对无信号盲区进行处理，其主要的场景如图 1和图 2所示： 一个用户终端在某个小区处于激活 Active状态， 如图 1或图 2中 Serving (服务 ) BS ( Base Station, 基站 )覆盖区域位置 1。 RSSI>R, SNR<S, INR>N (with signal dead zone, ie degenerated interference) or RSSI < R, SNR < S, INR > N (no signal dead zone). The embodiment of the present invention mainly deals with a signal-free blind zone. The main scenario is as shown in FIG. 1 and FIG. 2: A user terminal is in an active Active state in a certain cell, as shown in FIG. 1 or FIG. 2 (Serving) BS ( Base Station, base station) coverage area location 1.

1 , 用户终端在移动过程中从有网络信号的区域进入盲区， 如图 1或图 2中位置 2所在的区域，用户终端可以通过接收到的 RSSI、SNR 以及 INR值来判断是否进入无信号盲区， 在盲区内用户终端接收不 到网络的任何信息时， 记录检测信息， 所述检测信息包括服务基站的 标识。 其中， 用户终端记录检测信息具体可以为用户终端记录预设时 间内的检测信息。  1. The user terminal enters the blind zone from the area with the network signal during the mobile process. As shown in Figure 1 or Figure 2, the user terminal can determine whether to enter the no-signal blind zone by receiving the RSSI, SNR and INR values. When the user terminal does not receive any information of the network in the blind zone, the detection information is recorded, and the detection information includes the identifier of the serving base station. The user terminal records the detection information, and specifically, the user terminal records the detection information in the preset time.

2, 当用户终端继续移动， 从盲区又回到了有网络信号的区域时， 如图 1中的 Target BS(目标基站）覆盖区域位置 3或图 2中的 Serving BS覆盖区域位置 3, 用户终端根据重获信号时检测得到的测量信息 获得目前的盲区相关信息。  2. When the user terminal continues to move and returns from the blind spot to the area with the network signal, the Target BS (target base station) coverage area position 3 in FIG. 1 or the Serving BS coverage area position 3 in FIG. 2, the user terminal is based on The measurement information detected when the signal is recovered obtains the current blind zone related information.

3 , 用户终端经过网络侧设备的确认后， 将获取的盲区相关信息 向网络侧设备报告。 具体包括： 用户终端与重获信号的网络侧设备建 立通信通道； 所述用户终端向网络侧设备发送指示信息， 表明所述用 户终端之前进入过盲区， 需要上报盲区相关信息； 网络侧设备判断是 否需要进行盲区检测信息上报，若不需要，进行正常的通信；若需要， 向所述用户终端发送盲区检测信息上报请求消息，该请求消息中可以 携带相关内容， 如分配给上报消息的资源位置； 所述用户终端通过响 应消息将所述网络侧设备需要上报的信息都统一报告给所述网络侧 设备。  3. After confirming the network side device, the user terminal reports the obtained blind zone related information to the network side device. Specifically, the user terminal establishes a communication channel with the network side device that regains the signal; the user terminal sends the indication information to the network side device, indicating that the user terminal has previously entered the blind zone, and needs to report the blind zone related information; The blind area detection information is reported, and if not, the normal communication is performed; if necessary, the blind area detection information reporting request message is sent to the user terminal, and the request message may carry related content, such as a resource location allocated to the reported message; The user terminal uniformly reports the information that the network side device needs to report to the network side device by using a response message.

4 , 网络侧设备由其中的盲区相关处理模块或设备来获取盲区的 位置。 具体的， 所述网络侧设备根据收到的所述用户终端上报的信息 进行盲区统计和位置计算， 得出盲区的位置信息。  4, the network side device is obtained by the blind zone related processing module or device to obtain the location of the blind zone. Specifically, the network side device performs dead zone statistics and location calculation according to the received information reported by the user terminal, and obtains location information of the blind zone.

在以上动态移动的过程中， 用户终端和网络侧的节点（如服务基 站或目标基站）存在一种通信机制或通信方法， 保证用户在需要向网 络侧报告盲区信息时有相关资源能够使用。 本发明实施例中一种检测盲区流程如图 3所示，具体包括以下步 骤： In the above dynamic movement process, the user terminal and the network side node (such as the service base) There is a communication mechanism or communication method for the station or the target base station to ensure that the relevant resources can be used when the user needs to report the blind spot information to the network side. A process for detecting a blind zone in the embodiment of the present invention is as shown in FIG. 3, and specifically includes the following steps:

步骤 301 , MS通过 Serving BS进行网络初始接入流程， 其中包 括 SBC ( SS Basic Capability, 用户基本能力）协商流程。 SBC协商 流程中包括可选步骤：协商 MS和网络侧是否支持用户辅助盲区检测 功能， 之后通过 Serving BS附着在网络上。  Step 301: The MS performs an initial network access process by using the Serving BS, where the SBC (SS Basic Capability) negotiation process is included. The SBC negotiation process includes optional steps: negotiating whether the MS and the network side support the user-assisted blind spot detection function, and then attaching to the network through the Serving BS.

步骤 302, MS在激活状态下， 通过服务网络得到信息， 通过关 联（association )方式记录盲区检测需要的相关信息， 之后由于移动， MS进入到无信号盲区即 RSSI < R, SNR < S, INR > N。  Step 302: In the activated state, the MS obtains information through the service network, records related information required for blind area detection by association, and then, by moving, the MS enters a no-signal dead zone, ie, RSSI < R, SNR < S, INR > N.

步骤 303, 当 MS移动出盲区， 即 MS接收到的 RSSI、 SNR低 于某一个阈值时， MS判断并记录下离开盲区的一些相关信息。  Step 303: When the MS moves out of the blind zone, that is, the RSSI and SNR received by the MS are lower than a certain threshold, the MS determines and records some related information about leaving the blind zone.

步骤 304, 对于如图 1所示情况， 即用户从 Serving BS覆盖区域 移动到盲区后， 再移动到目标基站（Target BS )覆盖区域的情况， 在 MS移动过程中，可能会得到 Target BS信号，在该 Target BS信号中， 得到相关信息后跟网络侧建立通信通道，通过该通信通道接入到网络 侧并跟网络侧 （例如 Target BS ) 交互盲区信息， 此后网络侧通过专 门模块或专门设备进行统计和计算出盲区的位置。对于如图 2所示情 况，即用户从 Serving BS覆盖区域移动到盲区后，再移动到 Serving BS 覆盖区域的情况， 在 MS移动过程中， 再次得到 Serving BS信号， 在 Serving BS信号中， 得到相关信息后跟网络侧建立通信通道， 通过该 通信通道接入到网络侧并跟网络侧（例如 Serving BS )交互盲区相关 信息，此后网络侧通过专门模块或专门设备进行统计和计算出盲区的 位置。  Step 304: For the case shown in FIG. 1, that is, after the user moves from the coverage area of the Serving BS to the blind area, and then moves to the coverage area of the target base station (Target BS), the Target BS signal may be obtained during the MS moving process. In the Target BS signal, the relevant information is obtained, and then the network side establishes a communication channel, and the communication channel accesses the network side and interacts with the network side (for example, Target BS) to exchange dead zone information, and then the network side performs statistics through a special module or a special device. And calculate the location of the blind spot. For the case shown in FIG. 2, that is, after the user moves from the Serving BS coverage area to the blind area and then moves to the Serving BS coverage area, the Serving BS signal is obtained again during the MS mobility process, and the relevant information is obtained in the Serving BS signal. The information is followed by a communication channel established on the network side, through which the communication channel accesses the network side and interacts with the network side (for example, Serving BS) to exchange blind zone related information. Thereafter, the network side performs statistics and calculates the location of the blind zone through a special module or a dedicated device.

上述实施例中的步骤 302是对无信号盲区检测上报过程，而实际 也可以去用类似方法对有信号盲区进行标识上 ·¾, 比如判断 RSSI > R, SNR < S, INR > N; 同时步骤 304调整为： MS在经过网络侧设备的确认后向网络侧 设备发送有信号盲区的标识和信息，使网络侧设备可以知道有信号盲 区情况， 根据一定时间内反馈的统计结果， 对有信号盲区附近网络蜂 窝小区覆盖进行调整。 本发明实施例一中，有 GPS或 OTDOA( Observed Time Difference of Arrival, 观察到达时间差异定位法）的情况下的用户终端协助检测 盲区实施例， 流程如图 4所示， 具体步骤如下： Step 302 in the above embodiment is a process for detecting a blind spot detection without signal, but actually, a similar method can be used to identify a signal dead zone, for example, determining RSSI > R, SNR < S, INR >N; At the same time, the step 304 is adjusted to: after the acknowledgment by the network side device, the MS sends the identifier and the information of the signal blind zone to the network side device, so that the network side device can know that there is a signal blind zone, according to the statistical result of feedback in a certain period of time, The network cell coverage near the signal dead zone is adjusted. In the first embodiment of the present invention, the user terminal assists in detecting the blind zone in the case of GPS or OTDOA (observed time difference of Arrival). The flow is shown in FIG. 4, and the specific steps are as follows:

步骤 401 , MS通过与 Serving BS交互进行网络初始接入流程， 其中包括 SBC协商流程。 SBC协商流程中包括可选步骤： 协商 MS 和网络侧是否支持 GPS/OTDOA功能，并可以协商用户设备和网络侧 是否支持盲区检测功能， 之后通过 Serving BS附着在网络上。  Step 401: The MS performs an initial network access procedure by interacting with the Serving BS, where the SBC negotiation process is included. The SBC negotiation process includes optional steps: Negotiate whether the MS/network side supports the GPS/OTDOA function, and negotiate whether the user equipment and the network side support the blind spot detection function, and then attach to the network through the Serving BS.

步骤 402, MS在激活状态下， 通过服务网络得到信息， 如服务 基站的标识 Serving BS ID等， 通过关联（ association )方式记录邻居 相关信息， 如邻居基站的标识列表（ the list of the neighbour BSs )等， 和 /或如果 MS定期进行了定位，则通过定位***得到 MS最后一次定 位信息等， 并保存。  Step 402: In the activated state, the MS obtains information through the service network, such as the identifier of the serving base station, the Serving BS ID, and the like, and records related information of the neighbor, such as the list of the neighbor BSs. Etc., and/or if the MS is periodically positioned, the last positioning information of the MS, etc., is obtained by the positioning system and saved.

步骤 403, MS进入到盲区， 即 MS接收到的 RSSI、 SNR低于某 一个阈值时， MS判断并记录下盲区的一些相关信息， 如进入盲区之 前最后一次 GPS/OTDOA定位信息等。  Step 403: The MS enters the blind zone, that is, when the RSSI and SNR received by the MS are lower than a certain threshold, the MS determines and records some related information of the blind zone, such as the last GPS/OTDOA positioning information before entering the blind zone.

步骤 404, 对于用户从 Serving BS覆盖区域移动到盲区后， 再移 动到 Target BS覆盖区域的情况， MS通过接收到的 RSSI、 SNR检测 值判断 MS进入到了有信号的网络中即退出了盲区， MS接入到新网 络中并建立通信通道； 然后， MS向网络侧发起定位请求， 随后开始 定位流程并得到 MS当前的位置信息； MS将在盲区过程中记录的信 息以及退出盲区的位置信息报告给 Target BS, Target BS将收到的报 告信息发送给盲区检测模块或设备， 并用某一个算法（如 GPS定位 算法、 OTDOA定位算法、 或 Cell_ID定位算法等）进行盲区统计和 位置计算， 得出盲区的位置信息。 对于用户从 Serving BS覆盖区域移动到盲区后，又移动到 Serving BS 覆盖区域的情况， MS 得到相关信息后跟网络侧重新建立通信通 道， MS通过建立的通信通道向 Serving BS发送定位请求消息并进入 定位流程得到当前位置， 随后通过报告流程与网络（如图 2 中的 Serving BS ) 交互盲区相关信息， 如进出盲区的 GPS/OTDOA定位信 息、 或进盲区前的 Serving BS ID 和邻居 BS ID 歹 ll表、 或 SNR/RSSI/CINR等； Serving BS将收到的盲区相关信息发送给专门的 模块或专门的设备， 并用某一个算法（如 GPS定位算法、 OTDOA定 位算法、 或 Cell_ID定位算法等）进行统计和计算出盲区的位置。 第三代合作伙伴计划）环境， 也可以应用于 IEEE 802.16标准环境， 只是两种应用环境中的实体名称有所区别。在以下实施例中，在 3GPP 环境中， 终端为 UE ( User Equipment, 用户设备） ， 基站为 Node B+SRNC ( Serving Radio Network Controller,服务无线网络控制器）， 其中， Node B 负责接收中转等功能， SRNC 负责处理调度等功能； 在 IEEE 802.16标准中， 终端为 MS, 基站为 BS。 两种环境中的实体 名称虽然不同， 但实际进行功能类似， 因此， 以下实施例以 3GPP环 境进行说明。 其中， 基于 Cell_ID的定位方法通过获取目标 UE的蜂窝小区的 ID来确定目标 UE所在的位置， 并提供给定位用户。 目标 UE处于不 同的状态， 如 CELL_DCH ( Dedicated Channel, 专用信道 ) (该状态 下， 在上行和下行给 UE分配一个专用物理信道， 根据 UE当前的活 动集可以知道 UE所在的小区， UE可以使用专用传输信道、 下行 /上 行共享传输信道或这些传输信道的组合） 、 CELL_FACH ( Forward Access Channel, 前向接入信道） （该状态下， 没有给 UE分配专用传 输信道， UE连续监听一个下行 FACH信道， 为 UE分配了一个默认 的上行公共信道或上行共享传输信道，使之能够在接入过程中的任何 时间内使用， UE的位置在小区级为 UTRAN( UMTS( Universal Mobile Telecommunications System, 通用移动通讯***) Terrestrial Radio Access Network, UMTS陆地无线接入网 )所知， 具体为 UE最近一 次发起小区更新时报告的小区）等， 当核心网发出 LCS ( LoCation Service, 位置定位业务） 的请求后， SRNC将查询 UE的状态， 如果 UE处于非激活状态， SRNC将对 UE进行寻呼， 以确定 UE所在的小 区的 ID。 为了提高精度， SRNC还可以采用 RTT ( Round Trip Time , 环路时长 ) (用于 FDD ( Frequency Division Duplex, 频分双工 ) 中 ) 或 Rx时间偏差 （用于 TDD ( Time Division Duplex, 时分双工 ) 中 ) 测量方法。当 UE处于软切换状态时，可能和多个小区处于链接状态， 通常由以下几种方法确定小区的 ID: 选择信号质量较好的小区； 选 择 UE和 Node B链接使用的小区； 选择最近与 UE有关的小区； 选 择 UE上一个使用的且还没有准备切换的小区； 选择到 Node B距离 最短的小区；选择在接收到 SRNC请求时与 UE处于链接状态的小区。 对小区的选择也可以基于 RTT 的测量或者 UE、 Node B 或 LMU ( Location Measurement Unit, 位置测量单元）收到的信号的功率强 度，其他如 IPDL ( Idle Period Downlink,下行链路空闲周期）或 SSDT ( Site Selection Diversity Transmit, 站点选择差异传输 )也可能用于 选择小区。在确定好小区的 ID后，还需要将小区的 ID转换为地理坐 标或服务区域。 以 RNC为中心的 CELL_ID定位方法如图 5所示，如 SAS ( Stand- Alone SLMU ( Serving Location Measurement Unit, 月良务 位置测量单元） ， 独立服务位置测量单元） 为中心的 CELL_ID定位 方法如图 6所示。 Step 404: After the user moves from the Serving BS coverage area to the blind area and then moves to the Target BS coverage area, the MS determines that the MS enters the signaled network and exits the blind area by using the received RSSI and SNR detection values. Accessing to the new network and establishing a communication channel; then, the MS initiates a location request to the network side, and then starts the location process and obtains the current location information of the MS; the MS reports the information recorded in the blind zone process and the location information of the exit blind zone to the Target BS, Target BS sends the received report information to the blind zone detection module or device, and uses an algorithm (such as GPS positioning algorithm, OTDOA positioning algorithm, or Cell_ID positioning algorithm) to perform blind zone statistics and position calculation to obtain the blind zone. location information. After the user moves from the coverage area of the Serving BS to the blind area and then moves to the coverage area of the Serving BS, the MS obtains the relevant information and then re-establishes the communication channel with the network side, and the MS sends a positioning request message to the Serving BS through the established communication channel and enters the positioning. The process gets the current location, and then interacts with the network (such as Serving BS in Figure 2) to exchange blind zone related information, such as GPS/OTDOA location information into and out of the blind zone, or Serving BS ID and neighbor BS ID 歹ll table before entering the blind zone. , or SNR/RSSI/CINR, etc.; the Serving BS sends the received blind zone related information to a dedicated module or a dedicated device, and performs statistics using an algorithm such as a GPS positioning algorithm, an OTDOA positioning algorithm, or a Cell_ID positioning algorithm. And calculate the location of the blind spot. The 3rd Generation Partnership Project environment can also be applied to the IEEE 802.16 standard environment, except that the entity names in the two application environments are different. In the following embodiments, in the 3GPP environment, the terminal is a UE (User Equipment), and the base station is a Node B+SRNC (Serving Radio Network Controller), where the Node B is responsible for receiving functions such as transit. SRNC is responsible for handling scheduling and other functions; in the IEEE 802.16 standard, the terminal is an MS and the base station is a BS. The entity names in the two environments are different, but the actual functions are similar. Therefore, the following embodiments are described in the 3GPP environment. The cell_ID-based positioning method determines the location of the target UE by acquiring the ID of the cell of the target UE, and provides the location to the located user. The target UE is in a different state, such as CELL_DCH (Dedicated Channel). In this state, the UE is allocated a dedicated physical channel in the uplink and downlink. According to the current active set of the UE, the UE can be known, and the UE can use the dedicated UE. a transport channel, a downlink/uplink shared transport channel, or a combination of these transport channels), CELL_FACH (Forward Access Channel) (in this state, no dedicated transport channel is allocated to the UE, and the UE continuously listens to a downlink FACH channel, The UE is assigned a default uplink common channel or uplink shared transport channel, so that it can be used at any time during the access process. The location of the UE is UTRAN at the cell level (UMTS (UMT) Telecommunications System (Universal Mobile Telecommunications System), known as the Terrestrial Radio Access Network (UMTS), specifically for the cell that was reported when the UE initiated the cell update last time, etc., when the core network issues LCS (LoCation Service, location location service) After the request, the SRNC will query the status of the UE. If the UE is in an inactive state, the SRNC will page the UE to determine the ID of the cell in which the UE is located. To improve accuracy, SRNC can also use RTT (Round Trip Time) (for FDD (Frequency Division Duplex)) or Rx time offset (for TDD (Time Division Duplex) ) Medium) Measurement method. When the UE is in the soft handover state, it may be in a link state with multiple cells. The ID of the cell is usually determined by the following methods: selecting a cell with better signal quality; selecting a cell used by the UE and the Node B link; selecting the nearest UE The relevant cell; selects a cell that is used by the UE and has not yet prepared for handover; selects a cell that has the shortest distance to the Node B; and selects a cell that is in a linked state with the UE when receiving the SRNC request. The selection of the cell may also be based on the measurement of the RTT or the power strength of the signal received by the UE, Node B or LMU (Location Measurement Unit), and others such as IPDL (Idle Period Downlink) or SSDT. (Site Selection Diversity Transmit) may also be used to select a cell. After determining the ID of the cell, it is also necessary to convert the ID of the cell into a geographic coordinate or a service area. The RELL-centric CELL_ID positioning method is shown in Figure 5. The positioning method of the CELL_ID centered on the SAS (Stand-Alone SLMU (Serving Location Measurement Unit), independent service location measurement unit) is shown in Figure 6. Shown.

OTDOA ( Observed Time Difference of Arrival, 观察到达时间差 异定位法）定位方法， 如图 4所示， UE测量不同基站的下行导频信 号， 得到不同基站的下行导频的 TOA ( Time of Arrival, 到达时刻）， 即所谓的导频相位测量。 根据测量结果， 并结合基站的坐标， 采用合 适的位置估计算法， 从而计算出 UE的位置。 实际的位置估计算法需 要考虑多个基站（3个或 3个以上）定位的情况， 因此算法比较复杂。 一般而言， UE测量的基站数目越多， 测量精度越高， 定位的性能改 变越明显， 算法也越复杂。 使用这种定位方法， 需要 UE所测量的基 站同时发送下行导频信号。 因此， 网络中的所有基站必须实现时间同 步， 一般可以通过在基站安装 GPS接收机或链接到时间同步网来实 现基站发送下行导频信号的同步。 OTDOA (observed time difference of Arrival) positioning method, as shown in FIG. 4, the UE measures the downlink pilot signals of different base stations, and obtains the TOA (Time of Arrival) of the downlink pilots of different base stations. ), the so-called pilot phase measurement. According to the measurement result, combined with the coordinates of the base station, an appropriate position estimation algorithm is used to calculate the position of the UE. The actual position estimation algorithm needs to consider the positioning of multiple base stations (3 or more), so the algorithm is more complicated. In general, the more the number of base stations measured by the UE, the higher the measurement accuracy, and the performance of the positioning is changed. The more obvious it becomes, the more complicated the algorithm is. With this positioning method, the base station measured by the UE needs to simultaneously transmit the downlink pilot signal. Therefore, all base stations in the network must implement time synchronization. Generally, the base station can synchronize the downlink pilot signals by installing a GPS receiver at the base station or linking to the time synchronization network.

When the last positioning is repeated to step 813, the SAS may include the last position estimate in the PCAP Position Initiation Response message sent to the SRNC.

基于 GPS的定位方法， 实现步骤如下： 网络侧接收到 GPS的辅 助信息； 网络侧将 GPS的辅助信息发送给 UE; UE得到 GPS的辅助 信息， 并计算出自己的准确位置； UE将位置信息发送给核心网。 基 于 GPS的定位方法的方式分为辅助方式和自主方式两种。  The GPS-based positioning method is implemented as follows: The network side receives the GPS auxiliary information; the network side sends the GPS auxiliary information to the UE; the UE obtains the GPS auxiliary information, and calculates its own accurate location; the UE sends the location information Give the core network. The methods based on GPS-based positioning methods are divided into auxiliary mode and autonomous mode.

其中， 辅助 GPS的定位方式， 将传统的 GPS接收机的大部分功 能移植到网络处理器上来实现， 需要天线、 RF单元和数据处理器等 设备。 网络侧向 UE发送一串极短的辅助信息， 包括时间、 可观测卫 星的清单、 卫星的多普勒参数和码相位搜索窗口。 这些参数有助于内 置 GPS模块减少 GPS信号的获取时间。辅助数据来自于经 UE的 GPS 模块处理后产生的伪距离数据， 且可持续数分钟。接收到这些伪距离 数据后， 相应的网络处理器或定位服务器能大致估算出 UE的位置， 网络侧增加必要的修正后， 能提高定位的精度。 Among them, the auxiliary GPS positioning method, which transplants most functions of the traditional GPS receiver to the network processor, requires antennas, RF units and data processors. The network side sends a string of very short ancillary information to the UE, including time, a list of observable satellites, a Doppler parameter of the satellite, and a code phase search window. These parameters help the built-in GPS module reduce the acquisition time of GPS signals. Auxiliary data comes from the UE's GPS The pseudo-distance data generated by the module processing can last for several minutes. After receiving the pseudo-distance data, the corresponding network processor or the positioning server can roughly estimate the location of the UE, and the network side can increase the accuracy of the positioning after adding necessary corrections.

其中， 自主 GPS的定位方式， UE包含了一个全功能的 GPS接 收机， 具有 UE辅助 GPS的定位方式中 UE的全部功能， 并且还具有 卫星位置和 UE位置的计算功能。 位置计算开始时， UE需要的数据 比 UE辅助的方式要多， 这些数据能够持续 4个小时以上或根据需要 进行更新， 通常包括时间、 参考位置、 卫星星历和时间校验参数等。 如果某些应用需要更高的精度， 则必须持续向 UE发送差分 GPS ( DGPS )信号。 DGPS信号在非常宽的地域范围内有效， 以一个参 考接收机为中心可服务于较宽的地域范围。 最终的位置由 UE自己计 算得出， 若需要， 此定位信息可以发送给任何应用。  Among them, the autonomous GPS positioning mode, the UE includes a full-featured GPS receiver, which has all the functions of the UE in the UE-assisted GPS positioning mode, and also has the calculation function of the satellite position and the UE position. At the beginning of the location calculation, the UE needs more data than the UE assists. The data can last for more than 4 hours or be updated as needed, usually including time, reference location, satellite ephemeris and time check parameters. If some applications require higher accuracy, they must continue to send differential GPS (DGPS) signals to the UE. The DGPS signal is effective over a wide geographical area and can serve a wide geographical area centered on a reference receiver. The final location is calculated by the UE itself and can be sent to any application if needed.

基于 RNC的网络辅助的 GPS定位方法， 如图 9所示， 包括以下 步骤：  The RNC-based network-assisted GPS positioning method, as shown in Figure 9, includes the following steps:

步骤 901 , CN中的应用程序发送 Location Request消息给网络侧 的 SRNC,请求目标 UE的位置信息。 SRNC将考虑请求以及 UTRAN 和 UE的定位能力。  Step 901: The application in the CN sends a Location Request message to the SRNC on the network side to request location information of the target UE. The SRNC will consider the request and the positioning capabilities of the UTRAN and UE.

步骤 902 ,根据 UE的能力， 网络侧的 SRNC发送携带 GPS辅助 信息的 GPS测量请求给 UE。 GPS辅助信息包括 GPS的参考时间、 卫星的 ID、 多普勒功率、 查找窗口和中心点、 星历表和时钟校正、 年历等。 根据 UE的能力， 网络侧发送 GPS定位请求给 UE。 如果步 骤 901的 Location Request消息中包含周期性报告信息， SRNC将周 期性请求周期性报告； 如果 UE没有足够的辅助信息执行测量， 将向 SRNC请求更多的辅助信息； 如果是基于 UE的定位方法， 则转步骤 908。  Step 902: According to the capability of the UE, the SRNC on the network side sends a GPS measurement request carrying the GPS auxiliary information to the UE. GPS assistance information includes GPS reference time, satellite ID, Doppler power, lookup window and center point, ephemeris and clock correction, almanac, and so on. According to the capabilities of the UE, the network side sends a GPS positioning request to the UE. If the Location Request message in step 901 includes periodic report information, the SRNC will periodically request periodic report; if the UE does not have enough auxiliary information to perform measurement, it will request more auxiliary information from the SRNC; if it is a UE-based positioning method , then go to step 908.

步骤 903 , 如果是基于 UE的定位方法， 在辅助信息发送到 UE 之前， SRNC将请求下列信息： LMU更新、 RTT测量等。 LMU将返 回 NodeB和 GPS的时间差给 SRNC; Node B返回 RTT测量给 CRNC。 如果 CRNC不是 SRNC, 则 CRNC将把这些信息转发给 SRNC。 步骤 904, 网络侧的 SRNC向 UE请求 GPS卫星伪范围的测量， 并请求其他信息。 SRNC可能向 UE请求 SFN-SFN Observed Time Difference测量和 Rx-Tx Timing Difference信息。 Step 903, if it is a UE-based positioning method, the SRNC will request the following information before the auxiliary information is sent to the UE: LMU update, RTT measurement, and the like. The LMU will return the time difference between the NodeB and the GPS to the SRNC; the Node B returns the RTT measurement to the CRNC. If the CRNC is not an SRNC, the CRNC will forward this information to the SRNC. In step 904, the SRNC on the network side requests the UE to measure the GPS satellite pseudo range and requests other information. The SRNC may request the SFN-SFN Observed Time Difference measurement and the Rx-Tx Timing Difference information from the UE.

步骤 911 , 如果在步骤 901和步骤 902中请求周期性 告， 将重 复步骤 905-步骤 910。 UE将在每个间隔时间发送一个新的位置估计。 如果 CN在步骤 901请求周期性报告，而 SRNC在步骤 902没有请求 周期性 告， SRNC将重复步骤 902-步骤 910。 SRNC将在每个间隔 时间发送一个新的位置估计给 CN, 直到位置报告的数目达到要求的 请求数目。  Step 911, if a periodic report is requested in step 901 and step 902, step 905-step 910 will be repeated. The UE will send a new location estimate at each interval. If the CN requests periodic reporting in step 901 and the SRNC does not request periodic reporting in step 902, the SRNC will repeat steps 902-step 910. The SRNC will send a new location estimate to the CN at each interval until the number of location reports reaches the requested number of requests.

SAS初始化的网络辅助的 GPS定位方法， 如图 10所示， 包括以 下步骤：  The SAS-initiated network-assisted GPS positioning method, as shown in Figure 10, includes the following steps:

步骤 1001 , CN中的应用程序发送 Location Request消息给 SRNC, 请求目标 UE的位置信息。 SRNC将考虑请求以及 UTRAN和 UE的 定位能力。  Step 1001: The application in the CN sends a Location Request message to the SRNC to request location information of the target UE. The SRNC will consider the request and the positioning capabilities of the UTRAN and UE.

步骤 1002, SRNC收到 Location Request消息中还包括周期性报 告消息、 以及包含在 PCAP Position Initiation Request中的 CELL_ID 和 UE的定位能力。 Step 1002: The SRNC receives the Location Request message, and includes a periodic report message and a CELL_ID included in the PCAP Position Initiation Request. And the positioning capabilities of the UE.

步骤 1003, 根据 UE的能力， SAS发送 PCAP Position Activation Request消息给 SRNC , 发起 GPS定位。 该消息包括 GPS辅助数据， 可能还包括周期性报告信息。 SAS可能提供多个 GPS的辅助数据。  Step 1003: According to the capability of the UE, the SAS sends a PCAP Position Activation Request message to the SRNC to initiate GPS positioning. The message includes GPS assistance data and may also include periodic reporting information. SAS may provide assistance data for multiple GPS.

步骤 1004, SRNC使用 RRC信令转发 SAS的定位请求到 UE。 Step 1004: The SRNC forwards the positioning request of the SAS to the UE by using the RRC signaling.

RRC信令可能还包括周期性报告信息。 The RRC signaling may also include periodic reporting information.

步骤 1005, 如果是 UE辅助的 GPS, SRNC从 UE请求 GPS卫 星伪范围信息和其他信息的测量。 SRNC可能向 UE请求 SFN-SFN Observed Time Difference测量和 Rx-Tx Timing Difference信息。 UE 返回 GPS卫星伪范围的测量信息和其他信息给网络。 如果需要， UE 也将返回 SFN-SFN Observed Time Difference测量和 Rx-Tx Timing Difference信息， 以及他们的时间戳给 SRNC。  Step 1005, if it is UE-assisted GPS, the SRNC requests measurement of GPS satellite pseudo-range information and other information from the UE. The SRNC may request the SFN-SFN Observed Time Difference measurement and the Rx-Tx Timing Difference information from the UE. The UE returns measurement information and other information of the GPS satellite pseudo range to the network. If required, the UE will also return SFN-SFN Observed Time Difference measurements and Rx-Tx Timing Difference information, along with their timestamps to SRNC.

步骤 1006, SRNC发送 PCAP Position Activation Response消息 给 SAS。 该消息包括步骤 1005中包含的信息。  In step 1006, the SRNC sends a PCAP Position Activation Response message to the SAS. The message includes the information contained in step 1005.

步骤 1007, SAS计算出定位估计和可选的速率估计。 如果在步 骤 1002 不携带周期性报告， SAS 将发送 PCAP Position Initiation Response消息给 SRNC。 该消息包括定位估计和可选的速率估计， 可 能还包括定位方法信息和定位估计的精度是否满足要求的精度。 否 则， SAS将发送 PCAP Position Periodic Result消息给 SRNC。 该消息 包括定位估计，可能还包括定位方法信息和定位估计的精度是否满足 要求的精度的指示。  In step 1007, the SAS calculates a location estimate and an optional rate estimate. If the periodic report is not carried in step 1002, the SAS will send a PCAP Position Initiation Response message to the SRNC. The message includes a location estimate and an optional rate estimate, which may also include whether the accuracy of the location method information and the location estimate meets the required accuracy. Otherwise, the SAS will send a PCAP Position Periodic Result message to the SRNC. The message includes a location estimate and may also include an indication of whether the location method information and the accuracy of the location estimate meet the required accuracy.

步骤 1008,如果是基于 UE的定位方法， UE通过 RRC信令返回 定位估计和可选的速率估计给 SRNC。 SRNC将定位估计和可选的速 率估计包含在 PCAP Position Activation Response消息中， 并转发给 SAS。 该消息可能还包括定位方法信息和定位估计的精度是否满足要 求的精度的指示。  Step 1008: If it is a UE-based positioning method, the UE returns a positioning estimate and an optional rate estimate to the SRNC through RRC signaling. The SRNC includes the location estimate and the optional rate estimate in the PCAP Position Activation Response message and forwards it to the SAS. The message may also include an indication of whether the location method information and the accuracy of the location estimate meet the required accuracy.

步骤 1009, SAS可能确认步骤 1008的定位估计（如 CELL_ID 信息） 。 如果在步骤 1002 不要求周期性报告， SAS 将发送 PCAP Position Initiation Response消息给 SRNC。 该消息包括定位估计和可 选的速率估计，可能还包括定位方法信息和定位估计的精度是否满足 要求的精度。 否则， SAS将发送 PCAP Position Periodic Result消息给 SRNC。 该消息包括定位估计， 可能还包括定位方法信息和定位估计 的精度是否满足要求的精度的指示。如果定位估计的信息不足， SRNC 将从步骤 1003重新启动新的定位流程。 In step 1009, the SAS may confirm the location estimate (eg, CELL_ID information) of step 1008. If periodic reporting is not required in step 1002, the SAS will send a PCAP Position Initiation Response message to the SRNC. The message includes location estimates and The selected rate estimate may also include whether the accuracy of the positioning method information and the positioning estimate meets the required accuracy. Otherwise, the SAS will send a PCAP Position Periodic Result message to the SRNC. The message includes a location estimate, which may also include an indication of whether the location method information and the accuracy of the location estimate meet the required accuracy. If the location estimate is insufficient, SRNC will restart the new location process from step 1003.

步骤 1010, SRNC传递定位信息和可选的速率估计给 CN。 该消 息还包括定位方法。 如果 CN要求定位估计的精度， 在 Location Response消息中将包括定位估计的精度是否满足要求的精度的指示。  In step 1010, the SRNC passes the positioning information and an optional rate estimate to the CN. The message also includes a positioning method. If the CN requires the accuracy of the location estimate, an indication of whether the accuracy of the location estimate satisfies the required accuracy is included in the Location Response message.

如果在步骤 1004请求周期性报告， UE在每个间隔时间发送一个 GPS 测量报告。 SRNC 将测量报告包含在 PCAP Position Periodic Report消息中，并转发给 SAS。 SAS可能计算出定位估计和可选的速 率估计， 并确认计算出的定位估计以及从 SRNC收到的定位估计， 并 将定位信息包含在 PCAP Position Periodic Result 消息中转发给 SRNC。 如果可以获得定位方法信息， SRNC会将定位方法信息转发 给 CN。 如果 CN要求定位精度， Location Response消息中将包括定 位估计的精度是否满足要求的精度的指示。 重复上述过程， 直到发送 的定位估计的次数达到要求的次数。 SAS可能将最后的定位信息包含 在 PCAP Position Initiation Response消息中发送给 SRNC, 由 SRNC 转发最后的定位估计给 CN。  If a periodic report is requested at step 1004, the UE transmits a GPS measurement report at each interval. The SRNC includes the measurement report in the PCAP Position Periodic Report message and forwards it to SAS. The SAS may calculate the location estimate and the optional rate estimate, and confirm the calculated location estimate and the location estimate received from the SRNC, and include the location information in the PCAP Position Periodic Result message and forward it to the SRNC. If the positioning method information is available, the SRNC forwards the positioning method information to the CN. If CN requires location accuracy, the Location Response message will include an indication of whether the accuracy of the location estimate satisfies the required accuracy. The above process is repeated until the number of times the positioning estimate is sent reaches the required number of times. The SAS may include the last positioning information in the PCAP Position Initiation Response message and send it to the SRNC, and the SRNC forwards the last positioning estimate to the CN.

如果在步骤 1004不要求周期性报告，但在步骤 1002要求周期性 报告， SAS将重复步骤 1003-步骤 1010, 直到发送的定位估计的次数 达到要求的次数，或 CN终止定位流程。当最后一次请求的步骤 1008, SAS将在 PCAP Position Initiation Response消息中包含最后的定位结 果发送给 SRNC。  If periodic reporting is not required in step 1004, but periodic reporting is required in step 1002, SAS will repeat steps 1003 - 1010 until the number of transmitted positioning estimates reaches the required number of times, or CN terminates the positioning process. At the last request step 1008, the SAS will send the final positioning result in the PCAP Position Initiation Response message to the SRNC.

以上介绍了 3GPP中规定的三种基本的定位方法， 它们可以在不 同情况下使用， 基于 CELL_ID的定位方法可以在定位精度要求较低 时使用； OTDOA方法可以在定位精度要求较高并且 UE和网络无 GPS 接收机装置时使用； 而基于 GPS 的定位方法则适用于定位精度要求 高且 UE和网络有 GPS装置时使用。另夕卜，这几种定位方法可以同时 混合使用， 以弥补彼此的不足。 例如， 同时使用基于 CELL_ID 和 OTDOA的定位方法，就可以在农村和密集城区获得较好的定位效果。 网络同时使用多种定位方法在不同的情况下为不同的应用和不同的 用户提供定位服务。 本发明实施例二中， 没有 GPS/OTDOA而只有 Cell_ID定位的情 况下的用户终端协助检测盲区实施例， 如图 11所示， 具体步骤如下： 步骤 1101 , MS通过与 Serving BS交互进行网络初始接入流程， 其中包括 SBC协商流程。 SBC协商流程中包括可选步骤： 协商 MS 和网络侧是否支持用户辅助盲区检测功能，之后通过 Serving BS附着 在网络上。 The above describes the three basic positioning methods specified in 3GPP, which can be used in different situations. The CELL_ID-based positioning method can be used when the positioning accuracy is low; the OTDOA method can require higher positioning accuracy and UE and network. It is used when there is no GPS receiver device; the GPS-based positioning method is suitable for use when the positioning accuracy is high and the UE and the network have a GPS device. In addition, these several positioning methods can be simultaneously Mixed use to make up for each other's shortcomings. For example, using CELL_ID and OTDOA-based positioning methods, you can get better positioning results in rural and dense urban areas. The network simultaneously uses multiple positioning methods to provide location services for different applications and different users in different situations. In the second embodiment of the present invention, the user terminal in the case where there is no GPS/OTDOA and only the Cell_ID is located is used to assist the detection of the blind zone embodiment. As shown in FIG. 11, the specific steps are as follows: Step 1101: The MS performs initial network connection by interacting with the Serving BS. Into the process, including the SBC negotiation process. The SBC negotiation process includes optional steps: Negotiating whether the MS and the network side support the user-assisted blind spot detection function, and then attaching to the network through the Serving BS.

步骤 1102, MS在激活状态下， 通过服务网络得到信息， 如服务 基站的标识 Serving BS ID等， 通过关联（ association )方式记录邻居 相关信息， 如邻居基站的标识列表 the list of the neighbour BS等， 并 緩存。  In step 1102, the MS obtains information through the service network, such as the identifier of the serving base station, the Serving BS ID, and the like, and records the neighbor related information, such as the list of neighboring base stations, the list of the neighbor BS, etc. And cache.

步骤 1103, MS进入到盲区， 即接收的 RSSI、 SNR低于某一个 阈值， INR高于某个阈值时， MS判断并记录保存盲区的一些相关信 息， 如进入盲区之前緩存的服务基站标识， 以及当时的邻居基站列表 信息等， 并关联到盲区相关信息。  Step 1103, the MS enters the blind zone, that is, the received RSSI and SNR are lower than a certain threshold. When the INR is higher than a certain threshold, the MS determines and records some related information of the saved dead zone, such as the serving base station identifier buffered before entering the blind zone, and The neighbor base station list information at the time, etc., and associated with the blind zone related information.

步骤 1104, 对于如图 1所示的情况， 即用户从 Serving BS覆盖 区域移动到盲区后， 再移动到 Target BS覆盖区域的情况； MS通过 接收到的 RSSI、 SNR, INR检测值判断 MS进入到了有信号的网络 中即退出了盲区， MS 接入到新网络中并建立通信通道， 然后， MS 向网络侧发送 MS在盲区过程中记录的信息以及退出盲区的信息， 即 进入盲区前的 Serving BS ID 和邻居 BS ID 歹 'J表、 或 RTD/SNR/RSSI/CINR等， 报告给 Target BS, Target BS将收到的报 告信息发送给盲区检测模块或设备， 并用某一个算法（如 CelUD定 位算法等）进行盲区统计和位置计算， 得出盲区的位置信息。  Step 1104: For the case shown in FIG. 1, that is, the case where the user moves from the Serving BS coverage area to the blind area and then moves to the Target BS coverage area; the MS determines that the MS has entered through the received RSSI, SNR, and INR detection values. In the network with signal, the blind zone is exited, the MS accesses the new network and establishes the communication channel. Then, the MS sends the information recorded by the MS in the blind zone and the information of the exit blind zone to the network side, that is, the Serving BS before entering the blind zone. ID and neighbor BS ID 歹 'J table, or RTD / SNR / RSSI / CINR, etc., reported to the Target BS, the Target BS sends the received report information to the blind zone detection module or device, and uses an algorithm (such as CelUD positioning algorithm) Etc.) Perform blind zone statistics and position calculations to obtain the location information of the blind zone.

对于如图 2所示的情况，即用户从 Serving BS覆盖区域移动到盲 区后， 再移动到 Serving BS覆盖区域的情况。 在 MS移动过程中， MS又回到服务基站 （如图 2中的 Serving BS )信号覆盖范围， 在此 信号中， MS得到相关信息后和网络侧建立通信通道， 此后 MS通过 该通信通道接入到网络侧并与 Serving BS (如图 2中的 Serving BS ) 交互盲区信息， 即进入盲区前后 RTD/SNR/RSSI/CINR 等， 最后， Serving BS将收到的盲区相关信息发送给专门模块或专门设备， 并用 某一个算法（如 CelUD定位算法等）进行盲区统计和位置计算， 得 出盲区的位置信息。 For the situation shown in Figure 2, that is, the user moves from the Serving BS coverage area to the blind After the zone, move to the coverage area of the Serving BS. During the MS mobile process, the MS returns to the coverage of the serving base station (such as Serving BS in FIG. 2). In this signal, after the MS obtains the relevant information, it establishes a communication channel with the network side, and then the MS accesses through the communication channel. Go to the network side and interact with the Serving BS (such as Serving BS in Figure 2) to exchange dead zone information, that is, RTD/SNR/RSSI/CINR before and after entering the blind zone. Finally, the Serving BS sends the received blind zone related information to the dedicated module or specializes. The device, and using an algorithm (such as CelUD positioning algorithm, etc.) to perform blind zone statistics and position calculation, and obtain the location information of the blind zone.

本发明实施例二中的定位算法与实施例一相同， 不再赘述。 本发明实施例三中，用户终端通过指示消息发送协助检测盲区信 息， 具体的流程如图 12所示， 包括以下步骤：  The positioning algorithm in the second embodiment of the present invention is the same as that in the first embodiment, and details are not described herein again. In the third embodiment of the present invention, the user terminal sends the assistance to detect the blind zone information by using the indication message. The specific process is as shown in FIG. 12, and includes the following steps:

步骤 1201 , MS通过 Serving BS进行网络初始接入流程， 其中包 括 SBC协商流程。 SBC协商流程中包括可选步骤： 协商 MS和网络 侧是否支持 GPS/OTDOA功能，并可以协商 MS和网络侧是否支持用 户辅助盲区检测功能， 之后通过 Serving BS附着在网络上。  Step 1201: The MS performs an initial network access procedure through the Serving BS, where the SBC negotiation process is included. The SBC negotiation process includes optional steps: Negotiate whether the MS/network side supports the GPS/OTDOA function, and can negotiate whether the MS and network side support the user-assisted blind spot detection function, and then attach to the network through the Serving BS.

步骤 1202, MS在激活状态下， 通过服务网络得到信息， 如服务 基站的标识 Serving BS ID等， 通过关联（ association )方式记录邻居 相关信息， 如邻居基站的标识列表 the list of the neighbour BSs等， 和 /或如果 MS 定期进行了定位， 则通过定位***得到 MS 最后一次 GPS/OTDOA定位信息等， 并保存。  Step 1202: In the activated state, the MS obtains information through the service network, such as the identifier of the serving base station, the Serving BS ID, and the like, and records related information of the neighbor, such as the list of neighboring base stations, the list of the neighbor BSs, etc. And/or if the MS is regularly positioned, the last GPS/OTDOA positioning information of the MS is obtained through the positioning system and saved.

步骤 1203, MS进入到盲区， 即 MS接收到的 RSSI、 SNR低于 某一个阈值时， MS判断并记录下盲区的一些相关信息， 如进入盲区 之前緩存的服务基站标识、 和 /或当时的邻居基站列表信息、 和 /或最 后一次定位信息等， 并关联到该盲区标识相关信息下。  Step 1203, the MS enters the blind zone, that is, when the RSSI and SNR received by the MS are lower than a certain threshold, the MS determines and records some related information of the blind zone, such as the serving base station identifier buffered before entering the blind zone, and/or the neighbor at the time. Base station list information, and/or last positioning information, etc., and associated with the blind spot identification related information.

步骤 1204, 对于如图 1所示的情况， 即用户从 Serving BS覆盖 区域移动到盲区后， 再移动到 Target BS覆盖区域的情况。 此时， MS 通过接收到的 RSSI、 SNR检测值判断 MS进入到了有信号的网络中 即退出了盲区， MS接入到 Serving BS网络中并建立通信通道；然后， MS向网络侧发送的其他消息或专用消息中携带一比特指示信息， 说 明该 MS之前进入过盲区， 现在需要上报盲区相关信息， 触发***进 入盲区检测处理流程阶段； 之后， Target BS根据某些信息， 如目前 的网络资源已经收集到的盲区信息情况，判断是否需要进行后续的盲 区检测信息上报流程。 若不需要， 用户在规定的时长后进行正常的通 信， 不然， Target BS则主动发送盲区检测信息上报请求消息， 消息 中携带盲区相关内容， 如需要上报的参数名、 分配给上报消息的资源 位置等。 接下来， 若 MS所需要上报的内容包括定位信息， 其 MS和 Target BS或其他邻居 BS要进行一个 GPS/OTDOA定位的流程，获得 MS的位置信息后， MS通过响应消息将 BS在请求消息中需要上报的 信息都统一报给 BS。 随后， Target BS将收到的报告信息发给盲区检 测模块或设备， 并用某一个算法（如 GPS定位算法、 OTDOA定位算 法、 Cell_ID定位算法等）进行盲区统计和位置计算， 得出盲区的位 置信息。 Step 1204, for the case shown in FIG. 1, that is, the case where the user moves from the Serving BS coverage area to the blind area and then moves to the Target BS coverage area. At this time, the MS judges that the MS enters the signaled network by the received RSSI and SNR detection value, and then exits the blind zone, and the MS accesses the Serving BS network and establishes a communication channel; then, The other message or the dedicated message sent by the MS to the network side carries a bit of indication information, indicating that the MS has entered the blind zone before, and now needs to report the blind zone related information, triggering the system to enter the blind zone detection processing flow phase; afterwards, the Target BS according to some information For example, if the current network resources have collected blind zone information, it is determined whether a subsequent blind zone detection information reporting process is required. If not required, the user performs normal communication after a specified period of time. Otherwise, the Target BS actively sends a blind spot detection information report request message, and the message carries the blind zone related content, such as the parameter name to be reported and the resource location allocated to the report message. Wait. Next, if the content that the MS needs to report includes the positioning information, the MS and the Target BS or other neighbor BSs perform a GPS/OTDOA positioning process, and after obtaining the location information of the MS, the MS sends the BS in the request message by using the response message. The information that needs to be reported is uniformly reported to the BS. Subsequently, the Target BS sends the received report information to the blind zone detection module or device, and uses a certain algorithm (such as GPS positioning algorithm, OTDOA positioning algorithm, Cell_ID positioning algorithm, etc.) to perform blind zone statistics and position calculation, and obtains the location information of the blind zone. .

对于如图 2所示的情况，即用户从 Serving BS覆盖区域移动到盲 区后， 再移动到 Serving BS覆盖区域的情况。 在 MS移动过程中， MS回到服务基站（如图 2中的 Serving BS )信号覆盖范围内， 在此 信号中， 其得到相关信息后和网络建立通信通道， 此后其通过此通信 通道接入到网络并与 Serving BS (如图 2中的 Serving BS )交互信息。 之后， MS会在向网络侧发送的其他消息或专用消息中携带一比特指 示信息， 说明该 MS之前进入过盲区， 现在需要上报盲区相关信息， 触发***进入盲区检测处理流程阶段。 之后， Serving BS根据一些信 息， 如目前的网络资源已经收集到的盲区信息情况， 判断是否需要进 行后续的盲区检测信息上报流程。 若不需要， 用户在规定的时长后进 行正常的通信； 不然， Serving BS则主动发送盲区检测信息上报请求 消息， 消息中携带盲区相关内容， 如需要上报的参数名 ( RSSI/ SNR/ CINR/ RTD/ RSSI/ SNR/ GPS/OTDOA information )、分配给上报消息 的资源位置等。 接下来， 若 MS所需要上报的内容包括 GPS/OTDOA 定位信息， MS和 Serving BS或其他邻居 BS要进行一个定位的流程， 获得 MS的位置信息后 , 通过响应消息将 BS在请求消息中需要上报 的信息都统一报给 BS; 随后， Serving BS将收到的报告信息发给盲 区检测模块或设备， 并用某一个算法（如 GPS定位算法、 OTDOA定 位算法、 CelUD定位算法等）进行盲区统计和位置计算， 得出盲区 的位置信息。 For the case shown in FIG. 2, that is, the case where the user moves from the coverage area of the Serving BS to the blind area, and then moves to the coverage area of the Serving BS. During the MS mobile process, the MS returns to the coverage of the serving base station (such as the Serving BS in FIG. 2). In this signal, after obtaining the relevant information, the MS establishes a communication channel with the network, and thereafter it accesses through the communication channel. The network interacts with the Serving BS (such as the Serving BS in Figure 2). Afterwards, the MS carries a bit of indication information in the other message or the dedicated message sent to the network side, indicating that the MS has entered the blind zone before, and now needs to report the blind zone related information, triggering the system to enter the blind zone detection processing flow stage. After that, the Serving BS judges whether the subsequent blind spot detection information reporting process needs to be performed according to some information, such as the blind spot information that has been collected by the current network resources. If not required, the user performs normal communication after a specified period of time; otherwise, the Serving BS actively sends a blind spot detection information report request message, and the message carries the blind zone related content, such as the parameter name to be reported (RSSI/SNR/CINR/RTD) / RSSI / SNR / GPS / OTDOA information ), the location of the resource assigned to the reported message, and so on. Next, if the content that the MS needs to report includes GPS/OTDOA positioning information, the MS and the Serving BS or other neighbor BSs need to perform a positioning process. After obtaining the location information of the MS, the information that needs to be reported by the BS in the request message is uniformly reported to the BS through the response message; then, the Serving BS sends the received report information to the blind spot detection module or device, and uses an algorithm (such as GPS positioning algorithm, OTDOA positioning algorithm, CelUD positioning algorithm, etc.) perform blind zone statistics and position calculation to obtain the location information of the blind zone.
