Description

最小化路测的方法及装置 技术领域 本发明涉及通信领域， 具体而言， 涉及一种最小化路测的方法及装置。 背景技术 为了降低运营商利用专用设备进行人工路测的成本和复杂性， 第三代伙伴组织计 戈 ij ( Third Generation Partnership Projects, 简称为 3GPP ) 在通用陆地无线接入网 (Universal Terrestrial Radio Access Network, 简称为 UTRAN, 包括： 基站 （Node B) 和无线网络控制器（RNC))和演进的通用陆地无线接入网（Evolved Universal Terrestrial Radio Access Network, 简称为 E-UTRAN, 包括： 演进基站 （eNB)) ***的版本 10 (Release-10) 开始引入最小化路测 （Minimization of Drive Test, 简称为 MDT)功能。 UTRAN对应的核心网 （Core Network, 简称为 CN) 包括： 宿主用户服务器 （Home Subscriber Server,简称为 HSS)、移动交换中心服务器（Mobile Switching Centre Server, 简称为 MSC Server) 服务的 GPRS支持节点 （Serving GPRS Support Node, GPRS - General Packet Radio Service, 简称为 SGSN - 通用分组无线业务）等。 E-UTRAN对应 的核心网 （CN) 包括： 宿主用户服务器 （HSS)、 移动管理实体 （Mobile Management Entity, 简称为 MME) 等。 最小化路测功能利用用户设备 （User Equipment, 简称为 UE, 或称为终端） 自动收集测量信息通过控制面 （Control Plane) 信令报告给无线接 入网（Radio Access Network,简称为 RAN,对于 UTRAN***指 RNC，对于 E-UTRAN ***指 e B)， 再通过无线接入网报告给操作维护*** （Operation And Maintenance, 简称为 OAM)的跟踪收集实体（Trace Collection Entity,简称为 TCE)，用于网络优化， 例如， 发现及解决网络覆盖问题。 目前， 最小化路测主要用于实现覆盖优化。  TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a method and apparatus for minimizing drive test. BACKGROUND OF THE INVENTION In order to reduce the cost and complexity of operators using manual devices for manual road test, the third generation partner organization, Third Generation Partnership Projects (3GPP), is in the Universal Terrestrial Radio Access Network. , referred to as UTRAN, includes: a base station (Node B) and a radio network controller (RNC), and an evolved universal terrestrial radio access network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN, including: an evolved base station (eNB) )) Version 10 (Release-10) of the system began to introduce the Minimization of Drive Test (MDT) function. The core network (Core Network, referred to as CN) corresponding to the UTRAN includes: a Home Subscriber Server (HSS), and a Mobile Switching Centre Server (MSC Server) serving GPRS support node (Serving) GPRS Support Node, GPRS - General Packet Radio Service, referred to as SGSN - General Packet Radio Service, etc. The core network (CN) corresponding to E-UTRAN includes: Host User Server (HSS), Mobile Management Entity (MME), and so on. Minimize the drive test function. The user equipment (User Equipment, referred to as UE, or terminal) automatically collects measurement information and reports it to the radio access network (Radio Access Network, RAN for short) through Control Plane signaling. The UTRAN system refers to the RNC, and the E-UTRAN system refers to the e B), and then reports to the Operation and Maintenance (OAM) Trace Collection Entity (TCE) through the radio access network. For network optimization, for example, to discover and resolve network coverage issues. Currently, minimizing drive tests is mainly used to achieve coverage optimization.
MDT 支持基于管理的 MDT ( Management based MDT ) 和基于信令的 MDT ( Signaling based MDT)。 基于管理的 MDT的激活过程通常是 （以 E-UTRAN***为 例， 以下均同） OAM发送包含 MDT配置的跟踪激活消息 （Trace session activation) 给 eNB以激活某些 UE的 MDT测量， eNB选择合适的 UE进行 MDT， 并将 MDT配 置信息发送给选中的 UE。 基于信令的 MDT的激活过程通常是 OAM发送包含 MDT 配置的跟踪激活消息（Trace session activation)消息给 HSS以激活某个 UE的 MDT测 量， HSS将该 UE的 MDT配置信息发送给 MME， MME将该 UE的 MDT配置信息发 送给 e B， eNB最终将 MDT配置信息发送给 UE。 基于信令的 MDT通常用国际移动 用户标识（International Mobile Subscriber Identity, 简称为 IMSI)或国际移动站设备标 识 (International Mobile Station Equipment Identity, 简称为 IMEI)来指定某个 UE， 或 再加上区域信息以限制 UE的选择。基于管理的 MDT和基于信令的 MDT激活消息中 包含来自 OAM 的跟踪参考 （Trace Reference) 信息， 其中， 包括公共陆地移动网络 (Public Land Mobile Network, 简称为 PLMN) 信息， 由移动国家码 （Mobile country code, 简称为 MCC) 和移动网络码 （Mobile Network code, 简称为 MNC) 组成。 MDT supports Management-based MDT and Signaling based MDT. The activation process of the management-based MDT is usually (taking the E-UTRAN system as an example, the following are the same). The OAM sends a Trace Session activation containing the MDT configuration to the eNB to activate the MDT measurement of some UEs, and the eNB selects the appropriate one. The UE performs MDT and sends the MDT configuration information to the selected UE. The activation process of the signaling-based MDT is usually that the OAM sends a Trace Session Activation message including the MDT configuration to the HSS to activate the MDT measurement of the UE, and the HSS sends the MDT configuration information of the UE to the MME, and the MME will The MDT configuration information of the UE is sent to the e B, and the eNB finally sends the MDT configuration information to the UE. Signaling-based MDT usually uses International Mobile Subscriber Identity (IMSI) or International Mobile Station Equipment International Mobile Station Equipment Identity (IMEI) is used to specify a certain UE, or to add regional information to limit the UE's selection. The management-based MDT and signaling-based MDT activation messages contain Trace Reference information from OAM, including Public Land Mobile Network (PLMN) information, by mobile country code (Mobile) The country code (abbreviated as MCC) and the mobile network code (MNC) are composed.
MDT的工作模式包括在无线资源连接控制（Radio Resource Control,简称为 RRC) 空闲状态（IDLE) "记录最小化路测 （logged MDT)"和无线资源控制 （RRC)连接状 态 （CONNECTED) "立即最小化路测 （immediate MDT)"。 记录最小化路测指 UE在 无线资源控制空闲状态 （对于 E-UTRAN***指 RRC_IDLE状态； 对于 UTRAN*** 还包括小区 _寻呼信道状态 （CELL_PCH ) 和 UTRAN 注册区 _寻呼信道状态 (URA_PCH)) 当所配置的条件满足时收集并存储相关测量信息用于以后在无线接入 网要求时再报告给无线接入网， 再通过无线接入网报告给 TCE。 立即最小化路测指 UE在无线资源控制连接状态（对于 E-UTRAN***指 RRC_CO NECTED状态；对于 UTRAN ***指小区 _专用信道状态 （CELL_DCH)， 目前， 小区 _前向接入信道状态 ( CELL_FACH) 不支持立即最小化路测及记录最小化路测） 收集相关测量信息并当 报告条件满足时报告给无线接入网， 再通过无线接入网报告给 TCE。 The working mode of the MDT includes Radio Resource Control (RRC) idle state (IDLE) "recorded minimized drive test (logged MDT)" and radio resource control (RRC) connection status (CONNECTED) "immediately minimum Path test (immediate MDT). Recording minimized drive test means that the UE is in the radio resource control idle state (refer to the RRC_IDLE state for the E-UTRAN system; and includes the cell_paging channel state (CELL_PCH) and the UTRAN registration area_paging channel state (URA_PCH) for the UTRAN system) When the configured conditions are met, the relevant measurement information is collected and stored for later reporting to the radio access network when requested by the radio access network, and then reported to the TCE through the radio access network. Immediately minimizing the drive test means that the UE is in the RRC connection state (for the E-UTRAN system refers to the RRC_CO NECTED state; for the UTRAN system refers to the cell_dedicated channel state (CELL_DCH), currently, the cell_forward access channel state (CELL_FACH) It does not support immediate minimization of drive test and record minimization of drive test. Collect relevant measurement information and report it to the radio access network when the report conditions are met, and report it to the TCE through the radio access network.
RAN通过 RRC专用信令为 UE配置 logged MDT,配置内容主要包括无线（radio) 测量、 记录持续时间 （logging duration ) 记录周期 （ periodicity )、 记录触发条件 （如 周期性 Periodic或者基于事件 Event )、 绝对时间参考 （absolute time reference )、 区域 配置 （area configuration, 如小区列表 cell list或跟踪区列表 TA list; 没有配置区域范 围时时说明 logged MDT在 UE的注册公共陆地移动网络（Registered Public Land Mobile Network, 简称为 RPLMN) 范围内有效。 无线测量的内容包括下行导频强度测量 ( downlink pilot strength ) E-UTRAN ***中参考信号接收功率 (Reference Signal Received Power, 简称为 RSRP )、 UTRAN ***频分多路复用 （Frequency Division Duplex, 简称为 FDD)模式中公共导频信道（Common Pilot Channel, 简称为 CPICH) 接收信号码功率 （Received Signal Code Power, 简称为 RSCP)、 UTRAN*** FDD模 式 CPICH每调制比特与噪声谱密度比 Ec/No (Ratio of energy per modulating bit to the noise spectral density) UTRAN*** TDD模式主公共控制物理信道（Primary Common Control Physical Channel, 简称为 P-CCPCH) RSCP和干扰信号码功率 （Interference Signal Code Power, 简称为 ISCP)等。 UE根据 logged MDT配置所收集和存储的测量 内容还包括： 无线测量结果及对应的位置信息， 例如， 全球导航卫星*** （Global Navigation Satellite System, 简称为 GNSS) 位置信息或射频指印 （RF fingerprint) 信 息，和时间戳（time stamp)信息；时间戳为相对时间戳，相对于 UE接收到 logged MDT 配置时的绝对时间参考。 UE如果配置了 logged MDT且有存储的测量结果， 则在连接 状态无线资源控制连接建立完成消息 （RRC Connection Setup Complete ) 无线资源控 制连接重建立完成消息（RRC Connection Reestablishment Complete )、无线资源控制连 接重配置完成消息 （RRC Connection Reconfiguration Complete) 等消息中向无线接入 网报告记录最小化路测指示， 无线接入网通过 UE 信息请求消息 （UE information Request)通知 UE报告 logged MDT测量结果， UE在 UE信息响应消息（UE information Response)通过信令无线承载（SRB) (E-UTRAN中使用 SRB2、 UTRAN中使用 SRB4) 向无线接入网报告 logged MDT的测量结果。 Logged MDT所存储的测量结果在报告后 从 UE中清除， logged MDT配置信息在所配置的持续时间 （logging Duration) 超时后 清除， 如果无线接入网没有请求 UE报告 logged MDT， 则 logged MDT所存储的测量 结果在持续时间超时后 48小时以后清除。 相关技术中， UE仅在空闲状态根据 logged MDT配置进行相关测量信息的收集和 存储， 当 UE进入连接状态时， 停止上述行为； 当 UE重新进入空闲态时， 如果仍处 于所配置的记录持续时间范围内， 继续相关测量信息的收集和存储。 任意时刻， UE 仅支持一种无线接入技术（Radio Access Technology,简称为 RAT)特定的 logged MDT 配置， 当其它 RAT选择了同一个 UE配置 logged MDT时， 原来的 logged MDT配置 信息及记录内容被删除并被新的配置所取代。 UE仅在位于其配置了 logged MDT 的 RAT范围内收集并记录相关测量信息， 即 UE进入其它 RAT时， 停止上述行为， 也不 能报告所记录的测量结果； 当 UE重新进入其配置了 logged MDT的 RAT且处于空闲 状态时， 如果仍处于所配置的记录持续时间范围内， 继续相关测量信息的收集和存储。 Logged MDT配置信息也可以包括区域范围 （area scope) 信息， 该信息可以为小区列 表 （cell list) 或位置区列表 （LA list) 或 UTRAN注册区列表 （RA list), 非网络共享 情况下，区域范围属于同一个公用陆地移动网络（ Public Land Mobile Network, PLMN); 在没有配置区域范围的情况下， logged MDT配置在整个 PLMN范围内有效。 由此可见， 由于 UE仅在空闲状态进行相关测量信息的收集和存储， 对于连接态 的测量都是立即上报， 会导致信令开销比较大。并且有些测量记录得到之后， UE马上 转入了 IDLE态， 会导致测量结果没有办法立即上报到网络侧。 发明内容 本发明提供了一种最小化路测的方法及装置， 以至少解决相关技术中 UE对于连 接态的测量立即上报， 导致信令开销比较大的问题。 根据本发明的一个方面， 提供了一种最小化路测的方法。 根据本发明的最小化路测的方法包括： UE接收来自于网络侧设备的测量配置消 息； UE根据测量配置消息确定测量执行的状态，并在测量执行的状态下执行测量并保 存测量结果， 其中， 测量执行的状态包括以下之一： 空闲态； 连接态； 空闲态和连接 态； 当 UE进入连接态的过程中或处于连接态时， UE向网络侧设备发送有测量结果需 要上报的指示信息;

The configuration content mainly includes radio measurement, recording duration, periodicity, recording trigger condition (such as periodic Periodic or event-based Event), and absolute The time reference (absolute time reference), the area configuration (area configuration, such as the cell list cell list or the tracking area list TA list; when the area range is not configured, the logged MDT is registered in the UE's registered public land mobile network (Registered Public Land Mobile Network, referred to as Valid for RPLMN). Wireless measurement includes downlink pilot strength. Reference Signal Received Power (RSRP) in E-UTRAN system, UTRAN system frequency division multiplexing (Frequency Division Duplex, abbreviated as FDD) mode Common Pilot Channel (CPICH) Received Signal Code Power (RSCP), UTRAN system FDD mode CPICH per modulation bit and noise spectrum Density ratio Ec/No (Ratio of ene The UTRAN system TDD mode Primary Common Control Physical Channel (P-CCPCH) RSCP and Interference Signal Code Power (ISCP). The measurement content collected and stored by the UE according to the logged MDT configuration further includes: wireless measurement results and corresponding location information, for example, Global Navigation Satellite System (GNSS) location information or RF fingerprint information. And time stamp information; the timestamp is a relative timestamp, and the logged MDT is received relative to the UE. Absolute time reference at configuration time. If the logged MDT is configured by the UE and there is a stored measurement result, the RRC Connection Reestablishment Complete message (RRC Connection Reestablishment Complete) and the RRC Connection Reconnection Complete message are transmitted in the RRC Connection Setup Complete message. In the message such as RRC Connection Reconfiguration Complete, the report records the record minimization drive indication to the radio access network, and the radio access network informs the UE to report the logged MDT measurement result by using the UE information request message (UE information request), and the UE is in the UE. The information response message (UE information Response) reports the measurement result of the logged MDT to the radio access network through a Signaling Radio Bearer (SRB) (using SRB2 in E-UTRAN and SRB4 in UTRAN). The measurement result stored by the Logged MDT is cleared from the UE after the report. The logged MDT configuration information is cleared after the configured duration of the logging duration. If the radio access network does not request the UE to report the logged MDT, the logged MDT stores. The measurement results are cleared after 48 hours after the timeout expires. In the related art, the UE collects and stores related measurement information according to the logged MDT configuration only in the idle state, and stops the foregoing behavior when the UE enters the connected state; if the UE is still in the idle state, if it is still in the configured recording duration Within the scope, continue to collect and store relevant measurement information. At any time, the UE only supports one radio access technology (Radio Access Technology, RAT for short) specific logged MDT configuration. When other RATs select the same UE configuration logged MDT, the original logged MDT configuration information and recorded content are Removed and replaced by the new configuration. The UE collects and records related measurement information only within the RAT range in which the logged MDT is configured, that is, when the UE enters another RAT, the above behavior is stopped, and the recorded measurement result cannot be reported; when the UE re-enters the logged MDT configured by the UE When the RAT is in an idle state, if it is still within the configured recording duration, the collection and storage of related measurement information is continued. The Logged MDT configuration information may also include area scope information, which may be a cell list or a LA list or a UTRAN registration list (RA list), in the case of non-network sharing, the area The scope belongs to the same Public Land Mobile Network (PLMN); in the case of no configured area, the logged MDT configuration is valid throughout the PLMN. It can be seen that since the UE collects and stores related measurement information only in the idle state, the measurement of the connection state is immediately reported, which results in a relatively large signaling overhead. And after some measurement records are obtained, the UE immediately transfers to the IDLE state, which may result in the measurement result not being immediately reported to the network side.

Step S108: The UE receives the measurement result report request from the network side device, and reports the measurement result. In the related art, since the UE collects and stores the related measurement information only in the idle state, the measurement of the connection state is immediately reported, which results in a relatively large signaling overhead. And after some measurement records are obtained, the UE immediately switches to the IDLE state, which causes the measurement result to be reported to the network side immediately. In the method shown in FIG. 1, the measurement information is collected in both the connected state and the idle state by using the logged MDT method, and the measurement result is reported according to the measurement result of the network side device. The problem that the measurement of the connection state by the UE is immediately reported in the related art in the related art, which results in a relatively large signaling overhead, can effectively save signaling overhead.

Measure the status of execution. It can be seen that the UE can determine the state of measurement execution by using the above two methods, one is based on the network side. The indication information indicating the status of the measurement is sent to determine the status of the measurement execution; the other is based on the measurement target delivered by the network side device, and the UE can perform measurement according to the state that can be measured by itself, for example, some measurement target UEs Measurements can be made in both the idle state and the connected state, and measurements are made in both states.

Preferably, the measurement configuration message may also carry at least one of the following: radio measurement indication, recording period, the recording trigger condition (e.g., periodic or event-based Periodic E V ent), absolute time reference, area configuration, indicated by reference trace, Trace record session reference indication, Trace Collect Entity ID (TCE ID), measurement record retention time. In a specific implementation process, when the measurement configuration message carries the measurement record retention time, when the UE enters the connection state, after the UE sends the indication information that the measurement result needs to be reported to the network side device, the UE does not receive the network. The measurement result of the side device is reported. If the record storage time is greater than the received measurement record retention time, the UE can clear the recorded measurement record, thereby effectively saving the storage space capacity. In a preferred implementation process, for the evolved universal terrestrial radio access network E-UTRAN system, the UE carries the indication information that needs to be reported in the measurement result to be sent in one of the following messages: RRC connection establishment completion message, wireless The resource control connection re-establishment completion message, the RRC connection reconfiguration complete message, and the uplink message sent when the UE is in the connected state; for the UTRAN system of the universal terrestrial radio access network, the UE carries the indication information that needs to be reported.

In a preferred implementation, for the UTRAN system and the E-UTRAN system, the network side device carries the measurement result reporting request in the following message for sending: UE information request message. In a preferred implementation, for the UTRAN system and the E-UTRAN system, the UE carries the measurement result in the following message for reporting: UE information response message. Preferably, in step S108, the measurement result reported by the UE may include: a TCE identifier. By transmitting the identifier to the network side device, the network side device may map the measurement result to the signaling collection entity TCE according to the TCE ID and the IP address of the signaling collection entity. Through this process, the network side device can ensure that the measurement result is accurately reported. The above preferred embodiments are further described below in conjunction with FIGS. 2 through 5. 2 is a flow chart of a method of minimizing a drive test according to an example 1 of the present invention. As shown in FIG. 2, the method mainly includes the following processing: Step S202: The RAN receives an MDT measurement request from a CN or an OAM, where the measurement requirement includes a measurement target, a measured area configuration, and an IP address of Trace Collection Entity letter. Order to collect one or more of the entity's IP address and other content. Step S204: The RAN sends the logged MDT measurement configuration to the UE in the connected state by using dedicated signaling. Wherein, for the measurement requirement from 0AM, the RAN selects an appropriate UE to perform MDT measurement. The measurement configuration mainly includes measurement target, radio measurement, configuration of the logging duration, recording trigger condition (based on event Event), absolute time reference (absolute time referenced area configuration (area configuration) One or more of the list cell list or the tracking area list TA list), the traceReference, the TCE id, the state of the measurement execution, etc.; for example, the measurement target is Random access failure, and indicates that the measurement is for the idle state and the connected state, for example It can be indicated by two bits, for example, 00 means that measurement is only performed in the idle state, 01 means that it is only measured in the link state, and 11 means that it can be measured in the idle state and the connected state. Then the state of the measurement execution here is configured as 11. Step S206, UE Performing logged MDT measurement and storage. In a preferred implementation process, after the UE receives the measurement configuration message, the measurement configuration starts to take effect. The UE starts the measurement according to the indicated measurement state, and checks whether the current serving cell is in the regional configuration, and if so, Start, otherwise the measurement will not start. For example, U E starts the measurement of the RACH access failure in the connected state, and the UE may start the measurement of the RACH when the RACH process is started. For example, the method may include: starting radio signal quality measurement on the serving cell and the surrounding cell, and recording configuration information of the RACH access and the UE. The location information of the UE. When the RACH process fails, the UE stores the measurement result, and the UE may report the measurement result to the network side in the connected state, for example, when the stored measurement result exceeds a certain memory space size. When the UE transitions to the idle state, The UE continues to perform the measurement of the RACH access failure and records the result of the measurement. If the measurement configuration duration expires, the UE may clear the received measurement configuration and no longer perform the measurement. Step S208: The UE may use a new message in the connected state. Message 1 is reported to the network side, the network After receiving the message 1, the side determines whether to obtain the measurement result according to the situation. If the measurement result needs to be obtained, the message 2 is sent to the UE, and the UE is requested to send the logged MDT measurement result, and the UE reports the measurement result through the message 3. This only indicates the sequence relationship between message 1 and message 2. It does not limit the radio access network to send message 2 immediately after receiving message 1. If the base station receives message 1, it may request the UE to send the message after a long period of time. 2 (There may be other MDT-independent messages between Message 1 and Message 2). Specifically, in the E-UTRAN system, the message 1 is a RRC Connection Setup Complete message or a RRC Connection Reestablishment Complete message or a RRC connection reconfiguration complete message. (RRC Connection Reconfiguration Complete), where the available logged MDT indication (Log Meas Available) is carried. In the UTRAN system, message 1 is a radio resource control connection setup complete message (RRC)

Specifically: In the E-UTRAN system, message 2 is a UE information request message (UE Information Request in the UTRAN system, message 2 is a UE information request message (UE INFORMATION REQUEST) „ specific: in the E-UTRAN and UTRAN systems , message 3 is a UE information response message (UE Information
Response), 包含 RACH access failure信息、无线测量相关内容、位置信息、时间信息、 tce-Id、 trace Reference等其中的一项或多项。其中， RACH access failure信息可以包含Response), including one or more of RACH access failure information, wireless measurement related content, location information, time information, tce-Id, trace Reference, and the like. Wherein, the RACH access failure information may include
RACH失败原因和 RACH配置信息， 服务小区 id等其中的一项或多项。 若网络侧没有向 UE发送消息 2请求 UE上报测量结果，则 UE继续存储测量结果， 并可以多次上报有 logged MDT测量记录需要上报的指示。 直到超过一定时间门限， UE清除保存的测量结果。所述时间门限是测量配置中携带的测量记录保留时间或约定 的一个时间值。 步骤 S210、 网络侧获取到 logged MDT测量结果后， 根据 TCE id映射到信令收集 实体的 IP地址， 把测量结果发送到信令收集实体 TCE。 图 3是根据本发明实例二的最小化路测方法的流程图。 如图 3所示， 该方法主要 包括以下处理： 步骤 S302、 RAN接收到来自 CN或 OAM的 MDT测量需求， 其中， 该测量需求 中含有测量的目标、 测量的区域配、 IP address of Trace Collection Entity等内容中的一 项或多项。 步骤 S304、 RAN通过专用信令下发 logged MDT测量配置到链接态的 UE。其中， 对于来自 OAM的测量需求， RAN需要选择合适的 UE进行 MDT测量。 配置内容主 要包括测量目标、 无线 （radio)测量、 测量配置持续时间 （configuration of the logging duration ) 绝对时间参考 (absolute time reference )、 区域配置 (area configuration, 如 小区列表 cell list或跟踪区列表 TA list)、 trace Reference TCE id等其中的一项或多项； 其中， 测量目标为 radio link failure。 步骤 S306、 UE执行 logged MDT测量和存储。 在优选实施过程中， 在 UE接收到测量配置消息后， 根据指示的测量状态启动测 量， 并检查当前的服务小区是否在区域配置中， 若是则启动， 否则不启动测量。 例如， 测量目标为 radio link failure,则 UE只能在连接态开起测量。 UE在连接态检测到了 radio link failure, 则 UE记录测量的结果并存储， UE可以在进入连接态时上报测量结果到 网络侧。 可选的， UE在检到 radio link failure之前启动对服务小区和邻区的无线信号 质量的测量， 并只保留最后一次的测量结果直到检测到 radio link failure发生。 若测量 配置持续时间超时， 则 UE可以清除接收到的测量配置， 不再进行测量。 步骤 S308、 UE在消息 1中可以上报有 logged MDT测量记录需要上报的指示，无 线接入网接收消息 1后， 向 UE发送消息 2， 以请求 UE发送 logged MDT测量报告。One or more of the reasons for the failure of the RACH and the RACH configuration information, the serving cell id, and the like. If the network side does not send a message to the UE 2 and requests the UE to report the measurement result, the UE continues to store the measurement result, and may report the indication that the logged MDT measurement record needs to be reported multiple times. Until the threshold is exceeded, the UE clears the saved measurement results. The time threshold is a measurement record retention time or a predetermined time value carried in the measurement configuration. Step S210: After obtaining the logged MDT measurement result, the network side maps to the signaling collection according to the TCE id. The IP address of the entity sends the measurement result to the signaling collection entity TCE. 3 is a flow chart of a method of minimizing drive test in accordance with Example 2 of the present invention. As shown in FIG. 3, the method mainly includes the following processing: Step S302: The RAN receives an MDT measurement request from a CN or an OAM, where the measurement requirement includes a measured target, a measured regional allocation, and an IP address of Trace Collection Entity. One or more of the content. Step S304: The RAN sends the logged MDT to the UE in the link state by using the dedicated signaling. Among them, for the measurement requirements from OAM, the RAN needs to select an appropriate UE for MDT measurement. The configuration content mainly includes measurement target, radio measurement, configuration of the logging duration, absolute time reference, area configuration, such as cell list cell list or tracking area list TA list. One or more of trace Reference TCE id; where the measurement target is radio link failure. Step S306, the UE performs logged MDT measurement and storage. In a preferred implementation process, after receiving the measurement configuration message, the UE starts the measurement according to the indicated measurement state, and checks whether the current serving cell is in the area configuration, and if so, starts, otherwise the measurement is not started. For example, if the measurement target is radio link failure, the UE can only measure in the connected state. When the UE detects the radio link failure in the connected state, the UE records the result of the measurement and stores the result, and the UE may report the measurement result to the network side when entering the connected state. Optionally, the UE initiates measurement of the radio signal quality of the serving cell and the neighboring cell before detecting the radio link failure, and only retains the last measurement result until the detection of the radio link failure occurs. If the measurement configuration duration expires, the UE can clear the received measurement configuration and no longer perform measurement.

Until the threshold is exceeded, the UE clears the saved measurement result. The time threshold is the measurement record retention time or the agreed one carried in the measurement configuration. Time value. Step S310, after the network side obtains the logged MDT measurement result, according to the TCE id The IP address of the signaling collection entity is sent to the signaling collection entity TCE. Figure 4 is a flow chart of a method for minimizing the drive test according to Example 3 of the present invention. As shown in Figure 4, the method mainly includes the following Processing: Step S402: The RAN receives an MDT measurement requirement from the CN or the OAM, where the measurement requirement includes one or more items of the measured target, the measured regional allocation, and the IP address of Trace Collection Entity. S404: The RAN sends the logged MDT to the UE in the link state by using a dedicated message, where the RAN needs to select an appropriate UE to perform MDT measurement for the measurement requirement from the OAM.

In a preferred implementation process, after receiving the measurement configuration message, the UE starts the measurement according to the indicated measurement state, and checks whether the current serving cell is in the area configuration, and if so, starts, otherwise the measurement is not started. The measurement target is Qos, then the UE can only measure in the connected state. The UE performs periodic measurements according to the measurement configuration, and records the measurement results once every recording period and stores them. If the measurement configuration duration expires, the UE can clear the received measurement configuration and no longer perform measurements. Step S408: The UE may report an indication that the logged MDT measurement record needs to be reported in the message 1. After receiving the message 1, the radio access network sends a message 2 to the UE to request the UE to send the logged MDT measurement report. The UE reports the measurement result through the message 3. This only indicates the sequence relationship between message 1 and message 2. It does not limit the wireless access network to send message 2 immediately after receiving message 1. For example, after receiving the message 1, the base station may request the UE to send after a long time. Message 2 (There may be other MDT-independent messages between Message 1 and Message 2).

Until the threshold is exceeded, the UE clears the saved measurement result. The time threshold is the measurement record carried in the measurement configuration. Retaining time or a specified time value. Step S410: After obtaining the logged MDT measurement result, the network side maps to signaling according to the TCE id. The IP address of the entity is collected, and the Qos measurement result is sent to the signaling collection entity TCE.Figure 5 is a flowchart of a method for minimizing the drive test according to Example 4 of the present invention. As shown in Figure 5, the method mainly includes the following processing: S502. The RAN receives an MDT measurement requirement from the CN or the OAM, where the measurement requirement includes one or more items of the measured target, the measured regional allocation, and the IP address of Trace Collection Entity. Step S504, RAN The logged MDT is used to send the UE to the link state through the dedicated message.

The measurement configuration of the Qos measurement contains a periodicity. The measurement configuration of the RACH access failure measurement contains status information of the measurement execution, indicating that the UE is measuring in the idle state. Step S506, the UE performs logged MDT measurement and storage. In a preferred implementation process, after receiving the measurement configuration message, the UE starts the measurement according to the indicated measurement state, and checks whether the current serving cell is in the area configuration, and if so, starts, otherwise the measurement is not started. The measurement target is Qos, and the UE can only measure in the link state. The UE performs periodic measurements according to the measurement configuration, and records the measurement results once every recording period and stores them. The UE transitions to the idle state to enable the measurement of the RACH access failure when the regional configuration condition is met. The UE may start the measurement of the RACH when the RACH procedure is started. For example, the method may include: starting radio signal quality measurement on the serving cell and surrounding cells, and recording the RACH. The configuration information of the access and the location information of the UE, when the RACH process fails, the UE stores the measurement result. The time threshold is a measurement record retention time or a predetermined time value carried in the measurement configuration. If the measurement configuration duration expires, the UE can clear the received measurement configuration and no longer perform measurement. Step S508: The UE may report an indication that the logged MDT measurement record needs to be reported in the message 1. After receiving the message 1, the radio access network sends a message 2 to the UE to request the UE to send the logged MDT measurement report.

Specifically: In the E-UTRAN system, message 2 is a UE information request message (UE Information Request in the UTRAN system, and message 2 is a UE Information REQUEST) „ specific: In the E-UTRAN and UTRAN systems, the message 3 is a UE Information Response message, and includes one of Qos measurement information, wireless measurement related content, location information, time information, tce-Id, trace Reference, or the like. Multiple. The Qos measurement information includes: one or more of a throughput, a packet loss rate, and a packet delay indicator of the PDCP and or the RLC and or the MAC layer, and may also include a global identifier of the cell in which the measurement is performed. The RACH access failure information may include one or more of a RACH failure reason, a RACH configuration information, a serving cell id, and the like.

As shown in FIG. 6, the minimization drive test apparatus includes: a first receiving module 10 configured to receive a measurement configuration message from a network side device; and a determining module 20 configured to determine a state of the measurement execution according to the measurement configuration message, where The state of the measurement execution includes one of the following: an idle state; a connected state; an idle state and a connected state; a measurement module 30 configured to perform measurement and save the measurement result in a state in which the measurement is performed; and a transmitting module 40 configured to enter the connection at the UE In the process of the state or in the connected state, the network side device sends the indication information that the measurement result needs to be reported; the second receiving module 50 is configured to receive the measurement result report request from the network side device; the reporting module 60 is set to Report the measurement results. In the apparatus shown in FIG. 6, the measurement module 30 performs measurement information collection in both the connected state and the idle state, and the reporting module 60 reports the request to report the measurement result according to the measurement result of the network side device. The problem that the measurement of the connection state by the UE is immediately reported in the related art in the related art, which results in a relatively large signaling overhead, can effectively save signaling overhead. Preferably, the determining module 20 is configured to determine a state of the measurement execution according to the measurement target when the measurement configuration message carries the measurement target. Preferably, the determining module 20 is configured to determine a state of the measurement execution according to the indication information indicating the state of the measurement execution when the measurement configuration message carries the indication information indicating the state of the measurement execution and the measurement target. Preferably, the measurement module 30 may further include: a first processing unit configured to: When the measurement configuration duration is carried, the measurement is performed for the measurement duration in the state where the measurement is performed, and the measurement record is saved. When the state of the non-measurement execution is transferred to the measurement execution state for the duration of the measurement configuration, the measurement is continued and saved. Measurement record; The second processing unit, set to suspend the measurement configuration and save the measurement record when going to the state of non-measurement execution. Preferably, the foregoing measurement configuration message may further carry at least one of the following: a wireless measurement indication, a recording period, a recording trigger condition, an absolute time reference, an area configuration, a tracking reference indication, a tracking record session reference indication, a TCE identifier, and a measurement record reservation. time. In a preferred implementation process, the network side device configures the logged MDT for the UE through the RRC dedicated signaling, and the UE performs measurement according to the measurement configuration, and the configuration content mainly includes the measurement target, the radio measurement, and the measurement configuration duration (configuration of the logging duration). ), record the periodicity, record the horny condition (such as periodic Periodic or event-based Event), absolute time reference (area configuration, such as cell list cell list or tracking area list TA list) Tracking reference (trace collect entity ID), one or more of measurement execution status, measurement record retention time, etc.; UE first receiving module After receiving the logged MDT measurement configuration, the determining module determines the state of the measurement execution according to the measurement configuration message, wherein the state of the measurement execution includes one of the following: an idle state; a connected state; an idle state and a connected state; and a measurement module in the measurement configuration duration Measuring inside, The measurement result is recorded, and the sending module sends a log Meas Available indication to the UE in the connected state. After receiving the indication, the network side device may enable the UE to report the measurement report. The UE may report a log Meas Available indication in the connection state by using a message, where the message may be a message sent from the idle state to the link state, or an uplink message sent in the connected state. Further, for the logged MDT configuration, the network side device can set different measurement execution states for different measurement targets, such as: idle state, connected state, idle state, and connected state. The UE performs measurement only in the state in which the measurement is performed. In the state where the measurement is not performed, the suspended measurement configuration saves the measurement record, and continues to perform measurement when it is transferred to the measurement execution state for the measurement configuration duration. Further, for the logged MDT configuration, the UE may perform measurement according to the state that can be measured by the UE for different measurement targets. For example, some measurement target UEs may measure in both the idle state and the connected state, and then all are measured. For example, the measurement target periodic downlink pilot measurements, the serving cell becomes worse than threshold, the random access failure, the paging channel failure (Paging Channel Failure (Paging Channel Failure) PCCH Decode Error) Broadcast Channel Failure can be measured in idle state and connected state; measurement The target transmission power space is less than the threshold (Transmit power headroom becomes less than threshold). The radio link failure report, QoS (quality of service) performance and other measurement targets can only be measured in the connected state. INDUSTRIAL APPLICABILITY The technical solution of the present invention jointly considers that the measurement of the connection state by the UE is immediately reported, and the requirement of signaling overhead is reduced, and the measurement information is collected in both the connected state and the idle state by using the minimized drive test mode, thereby effectively saving the letter.
