Description

最小化路测方法、 系统和设备 本申请要求在 2010年 8月 13日提交中国专利局、申请号为 201010254002.5、 发明名称为"最小化路测方法、 系统和设备"的中国专利申请的优先权,其全部 内容通过引用结合在本申请中。 技术领域
本发明涉及无线通信领域, 尤其涉及一种最小化路测方法、 系统和设备。 背景技术
在未来的移动通信系统中, 希望通过引入网络侧自优化的机制, 减少网 络侧规划和操作维护的人工参与, 由网络侧根据统计量自动优化参数, 降低 网络侧的建设和运营成本。 为了减少网络侧的运维成本, 希望能够釆取网络 侧配置终端 (UE )上报方法, 减少人工路测的工作。 另一方面, 也希望能够 获得普通路测无法到达的区域的无线测量信息。
目前长期演进(LTE ) 系统中在第 10 版本(R10 ) 已经立项确定最小化 路测 (MDT )釆用控制面 ( control plane ) 的架构, 这种架构的好处就是基站 可以准确的控制 UE。 釆用控制面架构需要使用无线资源控制 (RRC )信令承 载网络侧对 UE进行的配置与 UE向网络侧的上 ^艮。 RRC信令要经过分组数 据汇聚协议(PDCP )层的加密、 完整性保护。
MDT测量分为实时 MDT ( Immediate MDT )测量和记录 MDT ( Logged MDT )测量, 具体如下:
Immediate MDT测量是 UE在连接态进行 MDT测量与上报。 复用无线资 源管理(RRM ) 测量机制, 一旦满足上报条件, 立即向基站、 无线网络控制 器( eNB/RNC )进行上报。
Logged MDT测量是 UE在空闲态进行 MDT测量, 在后续连接态进行上 报。 一旦满足了配置的触发条件, 将获取测量结果并进行记录(log ), 在后续 的合适时机上艮给 eNB/RNC。
MDT的 Log配置由网络侧在连接态下发给 UE,不基于现有 RRM测量进 行扩展, 而是定义了一种新的配置方法。 具体的:
在 UE侧, 当 UE释放掉 RRC连接时, 不会将接收到的 MDT log配置同 时释放, 而是继续保留并开启空闲态的 MDT测量与测量结果收集。
在网络侧, 当 UE释放掉 RRC连接时, 对于 Logged MDT , 网络侧不会 保留 MDT 上下文( context )信息,更不会将 MDT context进行网络侧的传递。 当 RRC连接释放时 , 网络侧保存的 MDT context也同时释放。
Logged MDT的情况下, 当 UE有可用的 log时, 如果进入连接态或者移 动到新小区, UE将把 log可用指示 ( Log available )通过 RRC信令上报给网 络侧。 以 LTE系统为例, RRC连接建立过程如图 1所示。
当成功建立了 RRC连接后, UE将会给网络侧发送 RRC连接建立完成 ( RRC Connection Setup Complete ) 消息, 此时该消息中携带 UE是否保存有 可用的 log的指示信息。 网络侧接收到该指示后, 可以后续请求 UE将保存的 MDT测量 log结果进行上报。
同样, 在 LTE的切换以及重建过程中, 如果 UE保存有 log结果, 将给切 换的目标小区 /重建到的小区发送 log available指示,通知新小区可用 log结果 的存在。
在通用移动通信系统 (UMTS ) 中, 如果发生了服务无线网络子系统 ( SRNS )重新定位( relocation )过程, UE也会将 log available指示发送给 更新后的目标小区。
现有的 MDT测量确定了如下 7个 UE需要测量的测量量:
Periodical downlink pilot measurements (周期下行导频测量 )、 Serving Cell becomes worse than threshold (业务小区变得比设定门艮差 )、 Transmit power headroom becomes less than threshold ( PHR 变得 t匕设定门艮差)、 Random access failure (随机接入失败)、 Paging Channel Failure (寻呼信道接收失败)、 Broadcast Channel failure (广播信道接收失败)、 Radio link failure report (无 线链路失败报告)。
除了上述 7 个测量量外, 在后续的标准进程中, 不排除增加其他的测量 量, 如 UE的服务质量(QOS )相关的测量量。 这些测量量中的若干个如果用 于连接态的 immediate MDT时, 当网络侧下发了这些测量的配置后, UE将在 连接态进行监测, 当有事件被触发后, 仍旧复用 RRM测量所使用的上报消息 进行到网络侧的上 ·¾。
在实现本发明的过程中, 发明人发现现有技术中存在以下技术问题: UE的 MDT测量结果数据的上报使用信号无线承载 2 ( SRB2 )进行承载, 如果其大小超过了 PDCP模块可以容纳的范围,在上报时将会出现问题: PDCP 模块无法承受大数据量的 RRC信令, 无法应用后续的安全性保护并发送给底 层进行上报, 从而导致 MDT测量结果数据的上报失败。 发明内容

本方案中, 终端接收到基站发来的上报 MDT测量结果的通知后, 若存储 的需要上报的 MDT测量结果数据的总数据量大于 PDCP模块能够容纳的数据 量, 则向基站上报一次或多次 MDT测量结果数据, 每次上报的 MDT测量结 果数据的总数据量不大于 PDCP模块能够容纳的数据量。 可见, 釆用本发明, UE上报的 MDT测量结果数据的数据量不会超过 PDCP模块能够容纳的数据 量, 从而解决了 UE上报的 MDT测量结果数据的数据量超过 PDCP模块可容 纳数据量所导致的 MDT测量结果数据上报失败的问题。
一种周期性 MDT测量方法, 该方法包括:

为了解决 UE上报的 MDT测量数据的数据量超过 PDCP模块可容纳数据 量时导致的 MDT测量数据上报失败的问题, 本发明实施例提供一种 MDT测 量结果上报方法, 本方法中, 终端在接收基站发来的上报 MDT测量结果的通 知后,若存储的需要上报的 MDT测量结果数据的总数据量大于 PDCP模块能 够容纳的数据量, 则向基站上报一次或多次 MDT测量结果数据, 每次上报的 MDT测量结果数据的总数据量不大于 PDCP模块能够容纳的数据量。
参见图 2, 本发明实施例提供的 MDT测量结果上报方法, 具体包括以下 步骤:
步骤 20: 终端接收基站发来的上报 MDT测量结果的通知;
步骤 21 : 终端在存储的需要上报的 MDT测量结果数据的总数据量大于 PDCP模块能够容纳的数据量时,向基站上报一次或多次 MDT测量结果数据, 并且每次上报的 MDT测量结果数据的总数据量不大于所述 PDCP模块能够容 纳的数据量。
步骤 21中, 终端向基站上报一次或多次 MDT测量结果数据, 其具体实 现可以釆用如下两种方案: 第一种, 具体如下:
A、 终端向基站发送携带还未被上报的 MDT测量结果数据的数据包, 该 MDT测量结果数据的总数据量不大于所述 PDCP模块能够容纳的数据量;
B、 终端确定是否再次接收到基站发来的上报 MDT测量结果的通知, 在 确定为是时, 返回步骤 。
第二种, 具体如下:
C、 终端向基站发送携带还未被上报的 MDT测量结果数据的数据包, 该 MDT测量结果数据的总数据量不大于所述 PDCP模块能够容纳的数据量;
D、终端确定是否存在还未被上报的 MDT测量结果数据,在确定为是时, 返回步骤 。
本方案中,在终端向基站发送携带还未被上报的 MDT测量结果数据的数 据包之前, 终端可以将用于表示所述数据包的发送顺序的序列号, 携带在所 述数据包中。
上述两种方案中,为了使得基站能够确定终端是否还有未上报的 MDT测 量结果数据或上报是否完成, 可以釆用如下三种方法:
第一种, 在终端接收基站发来的上报 MDT测量结果的通知之前, 终端向 基站发送记录可用指示消息, 该可用指示消息中携带有需要上报的携带 MDT 测量结果数据的数据包的数目信息。
第二种,终端向基站发送携带还未被上报的 MDT测量结果数据的数据包 之前, 将上报进程信息携带在该数据包中, 上报进程信息用于指示终端是否 还有未上报的 MDT测量结果数据。
第三种, 在终端接收基站发来的上报 MDT测量结果的通知之前, 终端向 基站发送记录可用指示消息, 该可用指示消息中携带有需要上报的携带 MDT 测量结果数据的数据包的数目信息; 并且,
终端向基站发送携带还未被上报的 MDT测量结果数据的数据包之前,将 上报进程信息携带在该数据包中。
上述两种方案中, 可以通过 RRC协议的数据包格式限制终端每一次上报 的 MDT测量结果数据的数据量不大于 PDCP模块能够容纳的数据量,具体实 现如下:
首先,终端根据 MDT上报信令的设定格式在该数据包填写还未被上报的 MDT测量结果数据, 按照该设定格式填写的数据包携带的总数据量不大于所 述 PDCP模块能够容纳的数据量; 然后, 终端将填写有 MDT测量结果数据的 数据包发送给基站;
还可以通过终端的 RRC模块自身的统计计算, 主动控制每一次上报的 MDT测量结果数据的总数据量不会大于 PDCP模块能够容纳的数据量, 具体 实现如下:
首先, 终端在数据包填写还未被上报的 MDT测量结果数据, 并计算已填 写的 MDT测量结果数据的数据量;在该数据量小于所述 PDCP模块能够容纳 的数据量时, 继续在数据包填写 MDT测量结果数据, 且总体填写的总数据量 不大于所述 PDCP模块能够容纳的数据量; 然后, 终端将填写有 MDT测量结 果数据的数据包发送给基站。
参见图 3 , 本发明实施例还提供一种 MDT测量结果上报通知方法, 具体 包括以下步骤:
步骤 30: 基站在向终端发送上报 MDT测量结果的通知后, 接收到终端 上报的 MDT测量结果数据;
步骤 31 : 基站确定终端是否还有未上报的 MDT测量结果数据; 步骤 32: 基站根据确定结果判断是否需要再次向终端发送上报 MDT测 量结果的通知, 并在判断为是时再次向终端发送上报 MDT测量结果的通知。
步骤 31中, 基站可以根据携带 MDT测量结果数据的数据包中的上报进 程信息, 确定终端是否还有未上报的 MDT测量结果数据; 或者,
基站根据终端发送的可用指示消息中携带的需要上报 MDT 测量结果数 据包的数目信息, 确定终端是否还有未上报的 MDT测量结果数据; 或者, 基站根据携带 MDT 测量结果数据的数据包中的上报进程信息和终端发 送的可用指示消息中携带的需要上报 MDT测量结果数据包的数目信息,确定 终端是否还有未上报的 MDT测量结果数据。
步骤 32中基站可以在确定终端还有未上报的 MDT测量结果数据时, 再 次向终端发送上^艮 MDT测量结果的通知。
步骤 32中,基站还可以按照接收 MDT测量结果数据的顺序或携带 MDT 测量结果数据的数据包中的序列号,将接收到的各 MDT测量结果数据进行排 序后存储。
参见图 4, 本发明实施例还提供一种周期性 MDT测量方法, 具体包括以 下步骤:
步骤 40: 终端接收基站配置的 MDT 测量时间定时器信息, 该 MDT 测 量时间定时器的定时时长不大于设定时间长度, 该设定时间长度是终端按照 配置的 MDT 测量内容和 MDT 测量周期进行周期性 MDT测量时,测量得到 的 MDT测量结果数据的数据量达到 PDCP模块能够容纳的数据量所需的时间 长度; 这里的 MDT测量内容包括下行导频测量等。
步骤 41 : 终端在所述 MDT 测量时间定时器的定时时长内进行周期性 MDT 测量。
在步骤 41之后, 终端将存储的测量得到的 MDT 测量结果数据上报给基 站。 具体的:
终端在连接建立或连接重建或小区更新或切换完成过程中, 向基站发送 记录可用指示消息; 终端接收基站发来的上报 MDT测量结果的通知, 将存储 的 MDT 测量结果数据上报给基站。
参见图 5, 本发明实施例还提供一种 MDT测量时间定时器的配置方法, 具体包括以下步骤:
步骤 50: 基站确定终端在根据配置的 MDT 测量内容和 MDT 测量周期 进行周期性 MDT 测量时, 测量得到的 MDT 测量结果数据的数据量达到 PDCP模块能够容纳的数据量所需的时间长度;
具体的, 基站可以按照如下方法确定所述时间长度 T:
T =t*N= t* ( Q/q ), 其中, t为所述 MDT 测量周期, Q为 PDCP模块能 够容纳的数据量, q是对所述 MDT 测量内容进行一次测量所得到的数据量, N是在测量得到的 MDT 测量结果数据的数据量达到 Q,所需要进行的测量次 数。 这里的 MDT测量内容包括下行导频测量等。
步骤 51 : 基站向终端配置定时时长不大于所述时间长度的 MDT 测量时 间定时器信息, 以指示终端在该 MDT 测量时间定时器的定时时长内进行周 期性 MDT 测量。
下面结合具体实施例对本发明进行说明:
Logged MDT上报由网络侧控制, 但在网络侧通知 UE上报之前, UE会 给网络侧一个 log可用 ( log available ) 的指示通知。 该指示一般在建立过程 / 切换过程 /重建过程 /小区更新过程中进行发送, 其一般流程为图 6A所示:
UE从空闲状态进入连接状态, 或者在连接态更换了小区 (切换 /重建 /小 区更新), 将通知网络侧, 在上行 RRC信令中指示 log是否可用。 网络侧可以 在收到 log可用指示后, 请求 UE将可用的 log具体测量结果上报。
MDT log数据不能由 UE 主动上报给网络侧, 需要 UE 上报上述 log available指示告知 log的存在, 由网络侧决定是否进行 log数据获取。 如果网 络侧通知 UE上报 log结果, UE将储存的 log结果按照一定格式装入数据包, 向网络侧进行发送。
发明方案:如果一次 MDT测量配置后的上报量超过了 PDCP模块的承受 范围, 则在 RRC层进行分段, 分次进行上报; UE在每一条上报消息中指明 后续是否还有因大小原因未能上报的 log 结果; 网络侧解读每一条上报消息 后, 决定是否通知 UE继续上报 log结果; UE可以预先在上报 log available 的同时通知本次一共有多少条 log结果报告要进行发送;如果仅配置了周期性 log测量, 可以通过限制测量时间的定时器控制 UE的 log数据量, 以保证不 会超过 PDCP模块的限制范围。
实施例 1 :
图 6B中, UE在 MDT测量结果上报消息中, 指示后续是否还有 log结果 需要发送。 图 6C中, 每一个 Log结果上报信令中, 都会携带 log结果内容, 在上报 log结果的同时, 该信令中可以携带 lbit指示信息, 用于通知网络侧后续是否 还有 log结果需要上报, 即: 本次上报的数据包是否是 log结果的最后一个数 据包。 由于 log记录是 UE在不断的测量中有顺序的获取的, UE可以把 log 记录按照测量到的顺序进行存储,一旦填装向网络侧发送 log测量结果的数据 包时检测到数据量超过限制, 则不进行继续填装, 而是在数据包格式的相应 位置指示 "还有 log结果数据尚未填充, 将等待上报"。 UE将该数据包进行发 送, 网络侧接收后, 解析数据包内容获取上述指示, 决定是否再次向 UE获取 剩余的 log结果。
实施例 2:
UE接收一个网络侧的获取命令, 将所有存储的 log结果依次填入多个数 据包, 进行发送。
当网络侧向 UE发送通知上报 log结果的信令后,如果由于 PDCP模块容 量限制范围等原因, UE不能利用一个数据包将所有的 log结果发送完成, 则 分次发送。一条网络侧向 UE下发的通知信令可以允许 UE向网络侧发送一条 或多条 log结果上报信令, 可以将 log结果分别填入多个数据包中, 分多个 RRC信令发送给网络侧, 如图 6D所示。
由于 UE—般按照测量到的 log顺序进行存储, 所以希望上报顺序不会混 乱。 可以在每条上报信令中引入 "序列号", 使得网络侧在接收 UE的多条 log 结果上报信令后能够各自解析并将所有 log结果按照 UE的发送顺序进行排 列。
实施例 3:
UE在上报 log available时, 可以预先通知网络侧后续要上报的数据包数 量, 以便网络侧预留出充足的资源。
上报 log available指示可能是在连接建立 /连接重建 /小区更新 /切换完成过 程中, 此时如果 log 结果还未上报, 或者仅上报完成多个数据包中的几个, UE可以在向网络侧指示 log available的同时指示还有几个 log结果数据包等 待上报。
例如: 可以在 log available指示的平级添加一个整型格式 RestPackages: 【省略的部分】
logAvailable ENUMERATED {true} OPTIONAL, restPackages INTEGER (1..8) OPTIONAL,
【省略的部分】
上面在 log available后面添力口了一个 的 restPackages格式,最多可以 指示 8个 log上 ^艮消息的存在。 如果 logavailable出现, restPackage需要指示 为 1-8中的一个值;如果 logavailable的指示不出现,则相应的,这个 restPackage 也不出现, 表示为没有数据包等待上报。 根据上报策略的不同, 协议制定时, 上例中的 "8" 可以被指定为其他值。
或者:
【省略的部分】
logAvailable ENUMERATED {true} OPTIONAL, restPackages INTEGER (0..7),
【省略的部分】
上面在 log available后面添力口了一个 ^¾的 restPackages格式,最多可以 指示 8种情况。 如果 logavailable出现, restPackage需要指示为 1-7中的一个 值; 如果 logavailable的指示不出现, 则相应的, 这个 restPackage必须等于 0, 表示为没有数据包等待上报。 根据上报策略的不同, 协议制定时, 上例中的 "7" 可以被指定为其他值。 这种指示方法比上一种节省了一个比特, 同时可 以指示的数据包数量也减少了一个。
实施例 1与 3、 实施例 2与 3中的方法可以混合使用。
例如: UE可预先在指示 log available的同时告知网络侧一共有多少 log 结果数据包需要发送, 再进行实施例 1或实施例 2中的多次发送, 使网络侧 获知是否有数据包尚未发送过来, 或者是否发送完成。
实施例 4: 在有规律的周期性 log情况下, 由于网络侧能够事先预测上报量的大小, 也可通过限制测量时间的定时器控制 UE的 log数据量,以保证不会超过 PDCP 模块的限制范围。
由于在 R10阶段仅在空闲状态的 log MDT引入了周期性 log记录, 记录 的内容与周期都是网络侧来进行配置的。 网络侧通过计算,可以推导出 UE在 一定的记录周期间隔与记录内容条件下, 达到 PCPC模块容量限制所需要的 时间。 网络侧可以通过给 UE配置一次 MDT测量时间定时器的方式, 达到对 log结果数据量大小的控制。

本发明实施例提供的方案中, 基站确定终端在根据配置的 MDT 测量内 容和 MDT 测量周期进行周期性 MDT 测量时,测量得到的 MDT 测量结果数 据的数据量达到 PDCP模块能够容纳的数据量所需的时间长度, 向终端配置 定时时长不大于所述时间长度的 MDT 测量时间定时器信息, 终端在所述 MDT 测量时间定时器的定时时长内进行周期性 MDT 测量。可见,由于 MDT 测量时间定时器的定时时长不大于终端测量得到的 MDT 测量结果数据的数 据量达到 PDCP模块能够容纳的数据量所需的时间长度, 因此, 终端在 MDT 测量时间定时器的定时时长内进行周期性 MDT 测量后得到的数据量不会超 过 PDCP模块能够容纳的数据量, 也就不会出现 UE上报的 MDT测量结果数 据的数据量超过 PDCP模块可容纳数据量导致的 MDT测量结果数据上报失败 的问题。
