Immediate MDT, UE在连接态所进行的 MDT测量与上报, 通过 复用 RRM ( Radio Resource Management, 无线资源管理)测量的形 式, 一旦满足上报条件, UE立即对 eNB ( evolved Node B , 演进型基 站) /RNC ( Radio Network Controller, 无线网络控制器)进行测量结 果的上报。 Logged MDT, UE在空闲态进行的 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储存 ( log ), 在后续的合适时机上报给 eNB/RNC。
( 2 ) Logged MDT 配置
MDT的 Log配置由网络在连接态下发给 UE, 并不基于现有的
RRM测量进行扩展, 而是定义了一种新的配置方法。
在 UE侧, 当 UE释放掉 RRC ( Radio Resource Control, 无线资 源控制)连接时, 并不会将接收到的 Logged MDT配置同时释放, 而 是继续保留并开启空闲态的 log测量与测量结果收集。
在网络侧, 对于 Logged MDT, 网络不会保留 MDT context (上 下文)信息, 也不会将 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。
( 3 ) Logged MDT测量可用指示
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,则 UE需要将 Logged MDT测量可用指示(Log available )通过 RRC ( Radio Resource Control, 无线资源控制)信令 上报给网络。
以 LTE系统为例, RRC连接建立过程如图 1所示, UE首先向网 络侧发送 RRCConnectionRequest 消息, 网络侧向 UE 发送 RRCConnectionSetup消息; 当成功建立 RRC连接后, UE会向网络 侧 发 送 RRCConnectionSetupComplete 消 息 , 此 时 , 该 RRCConnectionSetupComplete消息中携带 UE是否保存有可用的 log 的指示信息, 当网络侧收到该指示后, 可以后续请求 UE将保存的 MDT测量 log结果进行上报。
同样的, 在 LTE的切换以及重建过程中, UE可以将给切换的目 标小区 /重建到的小区发送该 log available指示, 通知新小区是否在 UE有可用的 log结果。
另夕卜, 在 UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统) 系统中, 如果发生了 SRNS relocation过程, UE 也会将 log available指示发送给目标小区。
( 4 ) UMTS系统的 UE状态
UMTS系统下的 UE有五种状态, 分别为 Cell_DCH状态 (利用 专用信道进行通信过程的状态), CELL_FACH状态 (无需分配专用 信道,在公共 FACH/ RACH信道上传递消息的状态), CELL_PCH状 态 (只在下行方向侦听 PICH 信道上的寻呼指示消息时的状态)、 URA_PCH状态 (处于非连续接收, 在 URA范围内侦听 PICH消息 状态)、 idle (空闲)状态, 前四种归属于 RRC连接态, 各状态之间 的转移示意图如图 2所示。其中, idle状态的 UE可以通过 RRC连接 建立过程直接进入到 CELL_DCH 状态或 CELL_FACH 状态, 而 CELL_DCH状态或 CELL_FACH状态的 UE也可以通过 RRC连接释 放过程进入到 idle状态。
现有技术中,在 MDT的讨论中已经明确 UMTS中的 CELL_DCH 状态归属于 immediate MDT , 而 idle态归属于 logged MDT。
但是, 在实现本发明的过程中, 发明人发现现有技术中至少存在 以下问题:
在现有技术中并没有涉及 UE在 CELL_FACH状态、 CELL_PCH 状态和 URA_PCH状态下 MDT的处理方式。 发明内容

在 LTE系统中引入了 MDT技术, 并在 R10中确定 MDT将采用 控制面 (control plane ) 的架构, 这种架构的好处是基站可以准确的 控制 UE。采用控制面架构需要使用 RRC信令承载网络对 UE进行的 配置与 UE向网络的上报。 在 MDT技术中, 针对现有技术中并没有 涉及 UE在 CELL_FACH状态、 CELL_PCH状态和 URA_PCH状态下 MDT的处理方式的问题, 本发明实施例中提供一种 MDT信息的处 理方法和设备, 以根据 UMTS 系统的 UE 状态的特点, 在 CELL_FACH状态、 CELL_PCH状态和 URA_PCH状态下, UE能够 将 Logged MDT测量可用指示上报给网络侧,从而使得网络侧可以根 据 UE上报的情况合理的收集 MDT的数据。
下面将结合本发明中的附图, 对本发明中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明的一部分实施例, 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 在没有做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。 本发明实施例一提供一种 MDT信息的处理方法, 如图 3所示, 包括以下步骤: 步骤 301 ,在 CELL_PCH状态、 URA_PCH状态、或 CELL_FACH 状态下, 当用户设备中包含 logged MDT数据时, 所述用户设备向网 络侧发送 Logged MDT测量可用指示。

进一步的, 在 CELL_PCH状态下, 所述用户设备向网络侧发送 Logged MDT测量可用指示, 包括: 当发生 cell改变时, 所述用户设 备通过 cell update消息将所述 Logged MDT测量可用指示发送给网络 侧。
在 URA_PCH状态下, 所述用户设备向网络侧发送 Logged MDT 测量可用指示, 包括: 当发生 URA改变时, 所述用户设备通过 URA update消息将所述 Logged MDT测量可用指示发送给网络侧。
在 CELL_FACH 状态下, 所述用户设备向网络侧发送 Logged MDT测量可用指示, 包括: 所述用户设备通过无线承载建立过程、 无线承载重配置过程、 无线承载释放过程、 传输信道重配置过程、 物 理信道重配置过程、 或小区更新过程的上行消息将所述 Logged MDT 测量可用指示发送给网络侧。
需要注意的是,在 CELL_FACH状态下,如果 CELL_FACH状态 归属于 Logged MDT的 mute状态, 则 CELL_FACH状态为所述用户 设备的暂态, 所述用户设备在 CELL_FACH 状态下停止对 Logged MDT 的测量。
步骤 302 , 网络侧设备接收来自所述用户设备的 Logged MDT测 量可用指示。
其中,所述网络侧设备接收来自所述用户设备的 Logged MDT测 量可用指示, 包括: 所述网络侧设备接收所述用户设备通过上行消息 发送的所述 Logged MDT测量可用指示。
在 CELL_PCH状态下, 所述网络侧设备接收来自所述用户设备 的 Logged MDT测量可用指示, 包括: 当发生 cell改变时, 所述网络 侧设备接收所述用户设备通过 cell update 消息发送的所述 Logged MDT测量可用指示。
在 URA_PCH状态下,所述网络侧设备接收来自所述用户设备的 Logged MDT测量可用指示, 包括: 当发生 URA改变时, 所述网络 侧设备接收所述用户设备通过 URA update 消息发送的所述 Logged MDT测量可用指示。
在 CELL_FACH状态下,所述网络侧设备接收来自所述用户设备 的 Logged MDT测量可用指示, 包括: 在无线承载建立过程、 无线承 载重配置过程、 无线承载释放过程、 传输信道重配置过程、 物理信道 重配置过程、 或小区更新过程中, 所述网络侧设备接收所述用户设备 通过上行消息发送的所述 Logged MDT测量可用指示。
进一步的, 所述网络侧设备接收来自所述用户设备的 Logged MDT测量可用指示, 之后还包括: 所述网络侧设备根据所述 Logged MDT测量可用指示判断是否从所述用户设备获取 logged MDT数据; 如果是, 所述网络侧设备将所述用户设备转到 CELL_DCH状态, 并 在 CELL_DCH状态下从所述用户设备获取 logged MDT数据。
可见, 本发明实施例中, 根据 UMTS 系统的 UE状态的特点, 在 CELL_FACH状态、 CELL_PCH状态和 URA_PCH状态下, UE能 够将 Logged MDT测量可用指示上报给网络侧,从而使得网络侧可以 根据 UE上报的情况合理的收集 MDT的数据。 为了更加清楚的阐述本发明实施例提供的技术方案,以下结合具 体的实施例对该 MDT信息的处理方法进行详细论述。 本发明实施例 二提供一种 MDT信息的处理方法,该实施例中,以 UE为 CELL_PCH 状态为例。 假设 UE在 CELL_PCH状态下的 MDT 归属于 Logged MDT。
如图 4所示, 该 MDT信息的处理方法包括以下步骤:
步骤 401 , UE在 CELL_PCH状态下启动 Logged MDT的测量。 具体的, 当网络对 UE 进行了 Logged MDT 配置后, UE 在 CELL_PCH状态下会启动 Logged MDT的测量。
步骤 402, UE向网络侧发送 Logged MDT测量可用指示。
具体的, 当 UE在 CELL_PCH状态时存在 logged MDT数据时, 则 UE会向网络侧发送 Logged MDT测量可用指示。
其中,该 Logged MDT测量可用指示即为 Logged Meas Available, 用于表示 UE侧是否含有 logged MDT数据, 例如, 当 Logged Meas Available为 1时,表示 UE侧含有 logged MDT数据,而当 Logged Meas Available为 0时, 则表示 UE侧不含有 logged MDT数据。
需要注意的是, UE在 CELL_PCH状态时存在的 logged MDT数 据, 可以是 UE在 CELL_PCH状态下进行 Logged MDT的测量所得 到的 logged MDT数据,也可以是 UE在转移到 CELL_PCH状态之前, 在其他状态(例如, URA_PCH状态、 Idle状态等)进行 Logged MDT 的测量所得到的 logged MDT数据, 本发明实施例中不对该 logged MDT数据的来源进行限制,只要该 UE上包含(即存在) logged MDT 数据即可。
本发明实施例中, UE向网络侧发送 Logged MDT测量可用指示 的方式可以为 UE通过上行消息将 Logged MDT测量可用指示发送给 网络侧。 其中, 该上行消息可以根据实际情况具体选择, 在 UE与网 络侧不同的通信过程中,均可以通过上行消息将 Logged MDT测量可 用指示发送给网络侧。 在实际应用中, 可以基于现有的通信过程扩展 上行消息将 Logged MDT测量可用指示发送给网络侧,也可以新定义 上行消息将 Logged MDT测量可用指示发送给网络侧。
例如, 在 CELL_PCH状态下, 如果 UE发生小区改变时, 则 UE 会发起 CELL update过程, 如图 5所示的 CELL update过程示意图, 包括: ( 1 ) UE向网络发送 cell update消息; ( 2 ) 网络收到 UE的 cell update后, 向 UE发送 cell update confirm (确认) 消息。 可以看出, 基于该 CELL update过程, 通过扩展上行消息 cell update消息, 即可 以通过 cell update消息将 Logged MDT测量可用指示发送给网络侧。
又例如, 在 CELL update过程中, 如果 UE切换到 RNC时, 则 UE还会在移动性信息确认消息中上报 UE的能力, 如图 7所示的上 报 UE能力示意图, 包括: (1 ) UE向网络发送 cell update消息; (2 ) 网络收到 UE的 cell update后, 向 UE发送 cell update confirm消息; 息确认)消息。可以看出,基于该过程,如果 UE没有通过 cell update 消息将 Logged MDT测量可用指示发送给网络侧时, 则 UE可以通过 扩展上行消息移动性信息确认消息,即可以通过移动性信息确认消息 将 Logged MDT测量可用指示发送给网络侧。
步骤 403, 网络侧接收来自 UE的 Logged MDT测量可用指示。 其中, 网络侧将接收 UE通过上行消息发送的 Logged MDT测量可用 指示。
例如, 当 UE通过 cell update消息将 Logged MDT测量可用指示 发送给网络侧时, 则网络侧将通过 cell update消息接收 Logged MDT 测量可用指示。
步骤 404, 网络侧根据 Logged MDT测量可用指示判断是否从 UE获取 logged MDT数据。如果是,转到步骤 405, 否则, 结束流程。
具体的, 当接收到 Logged MDT测量可用指示后,根据该 Logged MDT测量可用指示中的 bit位, 网络侧即可以确定 UE 中是否存在 logged MDT数据(例如,当该 bit位为 1时表示 UE中存在 logged MDT 数据), 并当 UE中存在 logged MDT数据时, 根据自身的策略确定是 否从 UE获取 logged MDT数据。例如,网络侧需要 UE当前的 logged MDT数据时, 则确定从 UE获取 logged MDT数据, 如果网络侧不需 要 UE当前的 logged MDT数据时, 则确定不需要从 UE获取 logged MDT数据。
步骤 405 , 网络侧从 UE获取 logged MDT数据。 根据实际的需要, 网络侧可以在 CELL_PCH状态直接从 UE获 取 logged MDT数据,也可以将 UE从 CELL_PCH状态转移到其他状 态(例如, CELL_DCH状态)后, 在 CELL_DCH状态下从 UE获取 logged MDT数据,该获取 logged MDT数据的方式本发明实施例中不 再赘述。
以下结合在 cell update 消息中携带 Logged Meas Available的情 况对该 MDT信息的处理方法进行进一步的说明。
( 1 )在 cell update 消息中携带 Logged Meas Available
UE处于 CELL_PCH状态时, 当 UE发生小区改变后, UE会进 行 cell update过程, 如果 UE存在没有进行上报的 Logged MDT数据 时, 则 UE可以在 cell update 消息中携带 Logged Meas Available , 并 将 cell update 消息发送给网络。 当网络侧 (例如, 基站)收到这个 Logged Meas Available后,即可以决定是否将 UE转到 CELL_DCH进 行 logged MDT数据的获取,并通过 cell update confirm中的状态转变 指示, 指示 UE是否转移到 CELL_DCH进行 logged MDT数据的上 报。
可见, 本发明实施例中, 根据 UMTS 系统的 UE状态的特点, 在 CELL_PCH状态下, UE能够将 Logged MDT测量可用指示上报给 网络侧, 从而使得网络侧可以根据 UE上报的情况合理的收集 MDT 的数据。 本发明实施例三提供一种 MDT信息的处理方法, 该实施例中, 以 UE为 URA_PCH状态为例。假设 UE在 URA_PCH状态下的 MDT 归属于 Logged MDT。
如图 8所示, 该 MDT信息的处理方法包括以下步骤:
步骤 801 , UE在 URA_PCH状态下启动 Logged MDT的测量。 步骤 802, UE向网络侧发送 Logged MDT测量可用指示。
本发明实施例中, 步骤 801、 步骤 802的处理过程与步骤 401、 步骤 402的处理过程类似, 在此不再详加赘述。
具体的, 当 UE在 URA_PCH状态时存在 logged MDT数据时, 则 UE会向网络侧发送 Logged MDT测量可用指示。 即 UE向网络侧 发送 Logged MDT测量可用指示的方式可以为 UE通过上行消息将 Logged MDT测量可用指示发送给网络侧。
例如, 在 URA_PCH状态下, 如果 UE发生小区改变时, 则 UE 会发起 URA update过程, 包括: ( 1 ) UE向网络发送 URA update消 息;( 2 )网络收到 UE的 URA update后,向 UE发送 URA update confirm (确认) 消息。 可以看出, 基于该 URA update过程, 通过扩展上行 消息 URA update消息, 即可以通过 URA update消息将 Logged MDT 测量可用指示发送给网络侧。
步骤 803, 网络侧接收来自 UE的 Logged MDT测量可用指示。 其中, 网络侧将接收 UE通过上行消息发送的 Logged MDT测量可用 指示。
步骤 804, 网络侧根据 Logged MDT测量可用指示判断是否从
UE获取 logged MDT数据。如果是,转到步骤 805, 否则, 结束流程。
步骤 805 , 网络侧从 UE获取 logged MDT数据。
根据实际的需要, 网络侧可以在 URA_PCH状态直接从 UE获取 logged MDT数据, 也可以将 UE从 URA_PCH状态转移到其他状态 (例如, CELL_DCH状态)后,在 CELL_DCH状态下从 UE获取 logged MDT数据, 该获取 logged MDT数据的方式本发明实施例中不再赘 述。
其中,步骤 803-步骤 805的处理过程与步骤 403-步骤 405的处理 过程类似, 在此不再详加赘述。
以下结合在 URA update消息中携带 Logged Meas Available的情 况对该 MDT信息的处理方法进行进一步的说明。
UE处于 URA_PCH状态时, 当 UE发生 URA改变后, UE会进 行 URA update过程, 如果 UE存在没有进行上报的 Logged MDT数 据时, 则 UE可以在 URA update 消息中携带 Logged Meas Available , 并将 URA update 消息发送给网络。 当网络侧 (例如, 基站)收到这 个 Logged Meas Available后,即可以决定是否将 UE转到 CELL_DCH 进行 logged MDT数据的获取, 并通过 URA update confirm中的状态 转变指示, 指示 UE是否转移到 CELL_DCH 进行 logged MDT数据 的上才艮。
可见, 本发明实施例中, 根据 UMTS 系统的 UE状态的特点, 在 URA_PCH状态下, UE能够将 Logged MDT测量可用指示上报给 网络侧, 从而使得网络侧可以根据 UE上报的情况合理的收集 MDT 的数据。 本发明实施例四提供一种 MDT信息的处理方法, 该实施例中, 以 UE为 CELL_FACH状态为例。假设 UE在 CELL_FACH状态下的 MDT归属于 Logged MDT。
如图 9所示, 该 MDT信息的处理方法包括以下步骤:
步骤 901 , UE在 CELL_FACH状态下启动 Logged MDT的测量。 步骤 902, UE向网络侧发送 Logged MDT测量可用指示。
本发明实施例中, 步骤 901、 步骤 902的处理过程与步骤 401、 步骤 402的处理过程类似, 在此不再详加赘述。
具体的,当 UE在 CELL_FACH状态时存在 logged MDT数据时, 则 UE会向网络侧发送 Logged MDT测量可用指示。 即 UE向网络侧 发送 Logged MDT测量可用指示的方式可以为 UE通过上行消息将 Logged MDT测量可用指示发送给网络侧。
进一步的,本发明实施例中,可以在 UE发生从 CELL_FACH状 态到 CELL_DCH的状态转变时,通过相应的上行消息将 Logged MDT 测量可用指示发送给网络侧。
例如, 在 CELL_FACH状态下, 会发生无线承载建立过程( radio bearer establishment procedure ), 无线 载重酉己置过程 ( radio bearer reconfiguration procedure )、无线承载释放过程 ( the radio bearer release procedure )、传输信道重酉己置过程 ( the transport channel reconfiguration procedure )、物理信道重酉己置过程 ( the physical channel reconfiguration procedure )、 小区更新过程 ( CELL UPDATE procedure ) , 而在上述过 程中, UE即可以扩展相应过程的上行消息将 Logged MDT测量可用 指示发送给网络侧。 例如, 可以在上述过程相应的完成消息(成功消 息或失败消息等) 中携带 Logged Meas Available。
步骤 903 , 网络侧接收来自 UE的 Logged MDT测量可用指示。 步骤 904, 网络侧根据 Logged MDT测量可用指示判断是否从 UE获取 logged MDT数据。如果是,转到步骤 905 , 否则, 结束流程。
步骤 905 , 网络侧从 UE获取 logged MDT数据。
根据实际的需要, 网络侧可以在 CELL_FACH状态直接从 UE获 取 logged MDT数据, 也可以将 UE从 CELL_FACH状态转移到其他 状态(例如, CELL_DCH状态)后, 在 CELL_DCH状态下从 UE获 取 logged MDT数据, 该获取 logged MDT数据的方式本发明实施例 中不再赘述。
其中,步骤 903-步骤 905的处理过程与步骤 403-步骤 405的处理 过程类似, 在此不再详加赘述。
、下结合 the transport channel reconfiguration procedure the transport channel reconfiguration complete 中携带 Logged Meas Available的情况对该 MDT信息的处理方法进行进一步的说明。
UE处于 CELL_FACH状态时,如果当前 UE存在没有进行上报 的 logged MDT数据, 而此时基站对 UE 的传输信道进行重配、 且基 站并没有将 UE的状态从 CELL_FACH转移到 CELL_DCH状态, 则 UE可以在 the transport channel reconfiguration complete中携带 Logged Meas Available , -^ the transport channel reconfiguration complete发 送给网络侧。 当网络侧收到这个 Logged Meas Available后, 即可以决 定是否将 UE转到 CELL_DCH进行 logged MDT数据的获取。
当 <然, ^口果 UE通过 the transport channel reconfiguration过程 ^!夺 UE从 CELL_FACH 转移到 CELL_DCH 状态, UE 同样会在 the transport channel reconfiguration complete 中携带 Logged Meas Available以通知网络侧。
另外, 需要注意的是, 上述处理过程为假设 UE在 CELL_FACH 状态下的 MDT归属于 Logged MDT, 如果^ 设 CELL_FACH状态归 属于 Logged MDT的 mute状态,也就是 CELL_FACH为 UE的暂态, 因此, UE可以针对这段时间(即 UE处于 CELL_FACH状态的时间) 并不触发对 MDT的测量, 即当 UE在 CELL_FACH状态时, UE会 停止对 Logged MDT 的测量和记录, 而配置的 Logged MDT 的 duration timer 可以根据实际需要选择继续运行或停止运行。
进一步的, 当 UE接收到 Logged MDT的配置后, 只有当 UE从 CELL_FACH转移到其他状态(例如, CELL_PCH状态或 URA_PCH 状态或 idle状态) 时, 才进行 MDT 的测量。
可见, 本发明实施例中, 根据 UMTS 系统的 UE状态的特点, 在 CELL_FACH状态下, UE能够将 Logged MDT测量可用指示上报 给网络侧,从而使得网络侧可以根据 UE上报的情况合理的收集 MDT 的数据。 基于与上述方法同样的发明构思,本发明实施例中还提供了一种 用户设备, 如图 10所示, 包括:
发送模块 11 , 用于在 CELL_PCH状态、 URA_PCH状态、 或 CELL_FACH状态下, 当用户设备中包含 logged MDT数据时, 向网 络侧发送 Logged MDT测量可用指示。

停止模块 13 , 在 CELL_FACH状态下, 如果 CELL_FACH状态 归属于 Logged MDT的 mute状态, 则 CELL_FACH状态为所述用户 设备的暂态, 用于在 CELL_FACH状态下停止对 Logged MDT 的测 量。
其中,本发明装置的各个模块可以集成于一体,也可以分离部署。 上述模块可以合并为一个模块, 也可以进一步拆分成多个子模块。 基于与上述方法同样的发明构思,本发明实施例中还提供了一种 网络侧设备, 如图 11所示, 包括:
