图 3为根据本发明又一实施例的获取终端的位置信息的装置的结构示意 图。
具体实施方式 为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发明 实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于本发明中 的实施例, 本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其 他实施例, 都属于本发明保护的范围。
为使得本发明中的实施例更加清楚完整, 下面对本发明实施例中一些概念 做简单阐述。
判断终端发生无线链路失败的方式有三种: 无线链路失败检测定时器超时、 终端的 RLC ( Radio Link Control, 无线链路控制)层数据重传达到预设的最大 次数或终端的 MAC ( Media Access Control , 介质访问控制 )层指示随机接入 失败。
其中, 根据无线链路失败检测定时器超时判断该终端发送无线链路失败的 具体过程为: 终端的 RRC ( Radio resource control , 无线资源控制)层如果从 终端的物理层连续接收到 P个失步指示时, 则开启无线链路失败检测定时器。 如果在无线链路失败检测定时器超时前,终端的 RRC层未从该终端的物理层连 续接收到 Q个同步指示时, 则说明该终端发生无线链路失败, 并生成相应的无 线链路失败测量报告, 该无线链路失败测量报告中至少包括发生无线链路失败 时的无线信号质量; 如果在该无线链路失败检测定时器超时前连续接收到 Q个 同步信息, 则停止无线链路失败检测定时器, 并判断该终端未发生无线链路失 败。 这里的 P均为大于 0的整数, 可根据实际需要自行设定。 在长期演进网络 ( Long-Term Evolution , LTE ) 中, P可以为 N310, Q可以为 N31 1 , 无线链 路失败无线链路失败检测定时器为 T310, 其中 N310、 N31 1和 T310的值是可 以根据实际需要自行配置的。 在通用移动通信系统 ( Universal Mobile Telecommunications System , UMTS ) P可以为 N313,Q可以 N315, 无线链 路检测定时器无线链路失败为 T313, 其中 N313、 N315和 T313的值也是可以 根据实际需要自行配置的。 N310、 N31 1和 T310以及 N313、 N315和 T313的具 体配置过程, 可参照现有技术, 此处不再赘述。
终端发生切换失败即终端从源小区切换到目标小区时, 在检测定时器规定 的时间内没有完成和目标小区的同步。 终端从源小区切换到目标小区的具体操 作为: 终端在接收到源小区发送的切换命令后, 开启自身的切换失败检测定时 器, 例如 LTE协议中切换失败检测定时器为 T304 timer, 然后检测目标小区, 当检测到目标小区后发起随机接入过程,如果在切换失败检测定时器超时前没 有切换到目标小区, 即与目标小区的随机接入失败或没有成功向目标小区成功 发送切换完成消息, 则判断终端发生切换失败, 并生成相应的切换失败测量才艮 告或统称为无线链路失败测量报告, 该切换失败测量报告或无线链路失败测量 才艮告中至少包括发生切换失败时的无线信号质量。
在 LTE系统中, RRC ( Radio Resource Control, 无线资源控制)连接建 立失败的判断条件是: 终端发送 RRC 连接请求消息 ( RRC Connection Request )消息时启动连接失败检测定时器 T300,如果在 T300超时前没有收到 RRC 连接建立消息 (RRC Connection Setup)消息, 则认为 RRC连接建立失 败, 如果在 T300超时前接收到了 RRC连接建立消息, 则认为 RRC连接建立成 功。 在通用移动通信系统中, 随机接入失败或随机接入成功时启动连接失败 检测定时器 T300, 发送 RRC 连接请求消息, 计数器 V300加 1 , 该计数器 V300 用来计算发送 RRC 连接请求消息的个数, 在 T300截止前没有收到 RRC 连接 请求消息则终端重新发起随机接入操作, 再次发送 RRC 连接请求消息, 计数 器 V300再次加 1 , 直到 V300达到预设的最大值时都没有收到 RRC 连接建立消 息, 则认为 RRC连接建立失败。
随机接入失败的判断条件可以是: 前导( Preamble )发送达到最大次数或 者是 MAC层随机接入循环达到最大次数。 实施例一
本实施例提供一种获取终端的位置信息的方法, 其适用于现有的网络架构 (例如 LTE系统) , 该网络架构包括终端和网络侧, 网络侧可包括基站或无线 网络控制器。 本实施例以终端为执行主体具体说明获取终端的位置信息的方 法。
如图 1所示, 为获取终端的位置信息的方法的流程示意图。 该获取终端的 位置信息的方法包括以下内容。
步骤 101 , 当判断出终端发生无线链路失败、 切换失败、 RRC连接建立失 败、 随机接入失败或终端预设统计值达到预设触发值, 或者判断出满足无线链 路失败预发生条件、 切换失败预发生条件或 RRC连接建立失败预发生条件时, 获取终端的位置信息。
可选地, 无线链路失败或切换失败预发生条件包括下列条件中的至少一 种:
无线链路失败预发生条件包括下列条件中的至少一种:
连续接收到的失步指示数量达到第一阔值;
无线链路失败失步检测定时器运行时间内接收到的同步指示个数达到第 二预设阔值;
无线链路失败失步检测定时器运行时间达到第三阔值;
RLC层数据重传次数达到第四阔值;
MAC层随机接入次数达到第五阔值。
可选地, 切换失败预发生条件包括:
切换失败检测定时器运行时间达到第六阔值。
此外,可选地, RRC连接建立失败预发生条件包括下列条件中的至少一种: RRC连接请求消息发送次数达到第七阔值;
连接失败检测定时器运行时间达到第八阔值。
需要特别指出的是, 上述所有的阔值可以是预先设定的, 或者是由网络侧 配置的。例如, 网络侧设备从终端获得支持该定位触发的能力信息和 /或网络设 备从核心网获得终端的签约信息后, 可以通知终端执行定位触发过程, 该网络 侧设备可以是基站或无线网络控制器。
另外, 终端预设统计值可以根据实际需要自行设定, 例如是物理层、 MAC ( Media Access Control )层、 RLC层、 PDCP(Packet Data Convergence Protocol, 分组数据汇聚协议)层或 IP ( Internet Protocol, 网际协议)层的数据 误码率、 调度的 IP吞吐量、 全部的业务吞吐量、 数据包的平均延迟值中的一个 或多个。 例如, 数码误码率 =终端错误接收到数据和总的发送数据的比值, 调 度的 IP吞吐量 =在激活时间内成功发送的数据和激活时间的比值, 全部的业务 吞吐量 =预设时间段内所发送的所有数据和这个预设时间段时间的比值,数据 包的平均延迟值 =预设时间段内数据包发送延迟的平均值。 具体地过程可以 为: 终端在预设时间段内统计预设统计值, 当预设统计值达到预设触发值时, 就触发终端进行定位。 终端预设统计值达到预设触发值可以由网络侧进行配 置。
终端可以通过以下方式中的至少一种执行定位: GPS(Global Positioning System, 全球定位系统)、 A-GPS ( Assisted-Global Position System, 网络辅 助的全球定位系统) 、 GANSS ( Galileo and Additional Navigation Satellite Systems )或 OTDOA ( Observed Time Difference of Arrival, 观察时间差) 。 其中, 如果釆用的卫星定位方法 (例如 GPS或 A-GPS或 GANSS定位或这三者 至少两者的联合定位方法), 可以获取终端的位置信息前还包含触发终端打开 GPS或 A-GPS或 GANSS接收机进行定位。
步骤 102, 向网络侧上报终端的位置信息。
可选地, 向网络侧上报终端的位置信息, 包括: 当判断出终端发生无线链 路失败、 切换失败、 RRC连接建立失败、 随机接入失败或终端统计值达到预设 触发值时, 生成测量报告; 向网络上报测量报告, 测量报告包括终端的位置信 息。 此时, 终端的位置信息和测量报告(例如, 无线链路失败测量报告、 切换 失败报告、 RRC连接建立失败报告、 随机接入失败报告或终端统计值达到预设 触发值时的报告等等) 同时向网络侧报告。
当然, 向网络侧上报终端的位置信息, 可以是通过任何可以携带该终端的 位置信息的消息, 向网络侧上报。 此时, 由于终端在定位过程中, 往往需要一 定的定位时间, 测量报告和终端的位置信息有可能不是同时向网络侧上报的。
根据本实施例的获取终端的位置信息的方法, 当判断出要发生无线链路失 败、切换失败预发生条件或 RRC连接建立失败, 或者判断出已经发生无线链路 失败、 切换失败、 RRC连接建立失败、 随机接入失败或终端预设统计值达到预 设触发值时, 获取终端的位置信息, 并向网络侧上报该终端的位置信息。 能够 使网络侧或者运营商获知哪些区域的网络发生了问题并进行及时地处理,从而 实现网络性能的优化。 举个例子, 网络侧统计发生某个区域无线链路失败、 切 换失败、 RRC连接失败或随机接入次数的比例大于预设门限值时, 则认为这个 区域的网络覆盖有问题, 可以釆取在该信号较差的覆盖或覆盖空洞区域布置 (或启用) 小型基站, 以提高该区域的无线网络性能。
更进一步, 本发明实施例中, 获取终端的位置信息的可选实施方式中, 将 卫星定位的方法引入到本发明实施例中获取终端位置信息, 不仅可以快速准确 的获取终端信息, 而且全天高精度持续作业, 不受天气影响。 实施例二
基于实施例一, 本实施例二提供一种获取终端的位置信息的方法。 该方法 包括以下内容。
步骤 201 , 判断终端是否发生无线链路失败、 切换失败、 RRC连接建立失 败、 随机接入失败或终端预设统计值达到预设触发值, 或者判断是否满足无线 链路失败预发生条件、 切换失败预发生条件或 RRC连接建立失败预发生条件, 当判断结果为是时, 获取终端的位置信息。 连续接收到的失步指示数量达到第一阔值;
无线链路失败失步检测定时器运行时间内接收到的同步指示个数达到第 二预设阔值;
无线链路失败失步检测定时器运行时间达到第三阔值;
RLC层数据重传次数达到第四阔值;
MAC层随机接入次数达到第五阔值。
可选地, 切换失败预发生条件包括:
切换失败检测定时器运行时间达到第六阔值;
可选地, RRC连接建立失败预发生条件包括下列条件中的至少一种: RRC连接请求消息发送次数达到第七阔值;
连接失败检测定时器运行时间达到第八阔值。
本实施例中的第一阔值、 第二阔值、 第三阔值、 第四阔值、 第五阔值、 第 六阔值、 第七阔值和第八阔值是可以根据实际需要预定义的, 或者是网络侧配 置的, 以上阔值均小于判断是否发生无线链路失败、切换失败或 RRC连接建立 失败的值。 例如, 当无线链路失败失步检测定时器运行时间内接收到的同步指 示个数达到 Q个时, 判断未发生无线链路失败, 则第二阔值小于 Q, 或者是切 换失败检测定时器运行时间达到 S时, 则判断出发生切换失败, 此时第四阔值 需小于 S。 又如, 当 RRC连接请求消息发送次数达到 R时, 则认为 RRC连接建 立失败, 此时第七阔值小于 R值。
步骤 202, 当判断出终端发生无线链路失败、 切换失败、 RRC连接建立失 败、 随机接入失败或终端统计值达到预设触发值时, 生成测量报告。
测量 告中包括各种各样的信息, 例如无线信号功率大小, 网络侧可以通 过该测量报告获取到发生无线链路失败、 切换失败、 RRC连接建立失败、 随机 接入失败或终端统计值达到预设触发值时的具体信息。
步骤 203, 当接收到网络发送的请求发送测量报告的请求并判断出未获取 到终端的位置信息时, 向网络发送测量 4艮告。
具体地, 发送测量^艮告的方法可以为: 终端需要先向网络发送携带测量报告可获得性指示的消息, 该可获得性指 示消息代表终端存储有测量报告, 例如, 在 LTE系统中, 该可获得性指示消息 可以携带在 RRC 连接建立完成 (RRC Connection Setup Complete)消息或 RRC连接重西己完成(RRC Connection Reconfiguration Complete)消息、或 RRC 连接重建完成消息 (RRC Connection Reestablishment Complete)等, 在
UMTS系统中, 该指示可以携带在接入网移动信息确认 (UTRAN Mobility Information Confirmation)消息或小区更新 ( Cell Update ) 消息。 网络收到携 带测量报告可获得性指示消息后, 请求终端上报测量报告, 比如可以通过终端 信息请求 (UE Information Request ) 消息请求终端上报测量报告。 终端收到 网络侧请求终端上报测量报告的请求消息后, 上 ^艮测量报告。
需要指出的是, 是否获取到终端位置信息与是否生成测量报告无关。 这是 由于, 终端进行定位操作时, 一般需要一定的定位时间。 而根据现有协议, 当 终端接收到网络发送的请求上报测量报告的消息时, 则根据不同请求向网络发 送不同的测量报告。 如果此时还未获取到终端的位置信息, 可以先向网络发送 测量报告, 待获取到终端的位置信息后, 再将获取到的与测量报告相关的有效 的位置信息向网络发送。
步骤 204, 当获取到终端的位置信息时, 向网络发送终端的位置信息。 具体地, 位置信息中可以包括与测量报告关联的标识和终端的位置, 并向 网络发送该位置信息。 这里的与测量 "^告相关的标识, 具体操作可以为: 在每 个测量 4艮告中加入网络中唯一的标识, 可以由发送该测量 4艮告的终端的电话号 号码与发送测量报告次数的组成, 例如是 " 13810005247-12 " ,
"13810005247"代表发送该测量报告的终端号码, "12"代表该终端是第 12 次发送测量报告, 相应地, 位置信息中也可以加入标识 "13810005247-12" , 以使网络识别该位置信息与哪个测量报告或者测量报告中的哪个网络问题相 关联。 这样, 在终端侧判断该位置信息是否有效的情况下, 当发生发送位置信 息不顺畅导致位置信息延迟发送(例如测量报告先发送, 由于定位需要一定时 间, 终端的位置信息可能在获取后才能向网络侧发送)时, 仍然可以使网络侧 接收到与测量报告相关联的精确的位置信息,从而避免了先向网络侧发送测量 报告,后向网络侧发送终端的位置信息,而导致的测量报告中携带的问题信息, 与发生该问题时终端的位置信息可能不匹配的问题。
可选地, 本发明实施例提供的获取终端的位置信息方法, 还可以包括: 判断位置信息是否有效, 当判断结果为是时, 才向网络侧上报终端的位置 信息。
该判断位置信息是否有效的步骤具体可包括:
根据获取位置信息与生成测量报告的时间间隔判断位置信息是否有效; 或 根据终端的移动速度判断位置信息是否有效。
由于终端的移动性, 当获取位置信息与生成测量报告(或发生无线链路失 败或切换失败时)的时间间隔过长时, 很有可能此时终端与有问题的网络的地 点间隔距离过长, 此时获取的终端的位置信息对该测量报告是无用的信息, 此 时可以选择不向网络发送位置信息。 这里的时间间隔可以根据实际需要是定义 的或可配置的或者是终端自行设置的或时间间隔是随速度变化的, 比如终端移 动速度越高, 则间隔越短。 例如获取到位置信息与生成测量报告的时间间隔在
5秒内时, 判断该位置信息有效, 可以在位置信息中加入与测量报告相关的标 识, 并向网络发送, 以使网络在接收到该位置信息时能够识别该位置信息与哪 个测量报告相关。
另外,同样定位装置进行定位均需要一定的时间,如果终端移动速度过快, 则会出现定位装置定位完成后, 终端已经距离发生无线链路失败或切换失败的 地点较远的情况, 此时获取的位置信息也是无效的。 具体地, 当终端的移动速 度小于预设阔值或者终端处于低速移动状态时, 判断此时获取的位置信息有 效。 这里的预设阔值可根据实际需要自行设定, 或者预定义的, 或者网络可配 置的, 比如 10公里 /时。 其中获得终端移动速度的准则可以为: 通过 GPS或 A-GPS或 GANSS获得终端移动速度; 或通过一定时间内终端重选和或切换的 小区个数来判断终端的移动速度, 比如一定时间内终端重选和或切换的小区个 数越多, 则终端的移动速度越高, 比如一定时间内终端重选和或切换的小区个 数小于一定门限, 则认为终端处于低速移动状态; 或一定时间内终端测量的 Pathloss (路径损耗) 变化越大, 则终端的移动速度越高, 比如一定时间内终 端测量的 Pathloss变化范围小于一定门限, 则认为终端处于低速移动状态。
可选地, 判断位置信息是否有效的操作可以由网络侧完成。 即终端生成测 量报告并向网络侧发送, 随后终端将获取的位置信息向网络发送, 网络根据接 收到测量报告与位置信息的时间间隔判断该位置信息是否有效。
具体地, 比如网络设备基于收到的位置信息与测量报告的时间进行关联, 比如收到位置信息的时间与测量报告的时间差小于某一个间隔, 则认为该位置 信息与该测量报告是关联的, 即认为该位置信息就是发生无线链路失败或切换 失败终端所处的位置; 或者网络设备基于位置信息中的时间戳和收到测量报告 的时间进行关联, 比如位置信息中的时间戳与网络设备收到测量报告的时间小 于某一个间隔, 则认为该位置信息与该测量报告是关联的; 或者网络设备基于 位置信息中的时间戳和测量报告中的时间戳进行关联, 比如位置信息中的时间 戳和测量报告中的时间戳之间的间隔小于一个间隔, 则认为该位置性能系与该 测量报告是关联的。
根据本实施例的获取终端的位置信息的方法, 当终端判断出要发生无线链 路失败或切换失败或者已经发生无线链路失败或切换失败时, 触发定位装置获 取位置信息, 并在判断出位置信息有效的情况下向网络发送, 可以使所获取的 位置信息更加精确, 以便使得运营商根据该位置信息更加准确地判断哪些地方 的网络出现了问题, 并对网络进行优化。 实施例三
本实施例基于上述实施例提供一种获取终端的位置信息的方法。
步骤 301 , 判断终端是否发生无线链路失败、 切换失败、 RRC连接建立失 败、 随机接入失败或终端预设统计值达到预设触发值, 或者判断是否满足无线 链路失败预发生条件、 切换失败预发生条件或 RRC连接建立失败预发生条件, 当判断结果为是时, 获取终端的位置信息。
该步骤的具体操作与实施例二中的步骤 201—致, 在此不再赘述。
步骤 302, 当判断出终端发生无线链路失败或切换失败时, 生成测量报告。 该步骤的具体操作与实施例二中的步骤 202—致, 在此不再赘述。
步骤 303, 当接收到网络发送的请求发送测量报告的请求且判断出获取到 终端的位置信息时, 将位置信息加入到该测量报告中。
步骤 304, 向网络侧发送该携带有位置信息的测量 4艮告。
发送测量 ^艮告的方式与上述实施例一致, 在此不再赘述。
可选地, 在获取到位置信息之后且在将位置信息加入到测量报告之前, 还 包括:
判断位置信息是否有效, 当判断结果为是时, 执行向网络上报终端位置信 息的操作。
具体如何判断位置信息是否有效, 与上述实施例一致, 在此不再赘述。 根据本实施例的获取终端的位置信息的方法, 当终端判断出要发生无线链 路失败或切换失败或者已经发生无线链路失败或切换失败时, 触发定位装置获 取位置信息, 并将该位置信息加入到测量 ^艮告中向网络侧发送, 可以使得运营 商根据该位置信息更加准确地判断哪些地方的网络出现了问题, 并对网络进行 优化。
