参阅图 2所示, eNB和 MME进行通信时, 两者定义的协议栈包含层 1 ( LI )、 L2 (层 2 )、 IP层、 SCTP ( Stream Control Transmission Protocol, 流控制传输协议)层、 S1应用协 议( SI Application protocol, S l-AP )层, 而 MME和增强的移动位置服务中心 (Enhanced Serving Mobile Location Centre, E-SMLC ) 进行通信时, 两者定义的协议栈包含 LI、 L2、 IP层、 SCTP层和 LCS-AP层;如图 1所示, eNB和 E-SMLC之间通过位置定位 a协议( LPPa 协议)进行通信, S 1为 eNB和 MME之间采用的接口, SLs为 MME和 E-SMLC之间采用 的接口。
其中, S 1-AP是 S 1接口应用协议, 为 eNB与 MME之间的接口协议, 用于承载两个 实体间的交互信息; SCTP为流控制传输协议, 与 IP协议等为底层传输协议; LCS-AP为 位置服务应用协议, 为 SLs接口上的定位相关协议。
如图 2所示, MME对 LPPa消息而言是完全透明的, S 1接口定义两个独立传输过程 来承载 LPPa消息; 分别是用户设备 ( UE )相关的信令和非 UE相关的信令, 前者用于传 输针对 UE的增强小区标识 ( E-CID ) 定位过程, 后者用于获取定位辅助数据。
UE相关的信令主要包括 DOWNLINK UE ASSOCIATED LPPA TRANSPORT消息 (下 行 UE相关 LPPa传输消息)和 UPLINK UE AS SOCIATED LPPA TRANSPORT消息(上行 UE相关 LPPa传输消息), 两种消息都包含 MME UE S 1AP ID ( MME UE S 1AP标识号) 和 eNB UE S1AP ID ( eNB UE S 1AP标识号), 两者分别在 MME和 eNB中唯一标识一个
用户; 此外, 上述两种消息中还应当包含有 Routing ID (路由 ID ), 用来标识定位会话发 起的 E-SMLC ,此 Rounting ID由 MME分配,通过以 DOWNLINK UE ASSOCIATED LPPA TRANSPORT消息发给每个 e B , 并在 UPLINK UE ASSOCIATED LPPA TRANSPORT消 息中带回, MME根据该 Rounting ID , 路由到正确的 E-SMLC。
非 UE相关的信令主要包括 DOWNLINK NON UE ASSOCIATED LPPA TRANSPORT 消息(下行 UE无关 LPPa传输消息 UPLINK NON UE ASSOCIATED LPPA TRANSPORT 消息 (上行 UE无关 LPPa传输消息), 这两种消息都包含 Routing ID, 其作用与 UE相关 的信令相同, 不再赘述。
现有技术下, eNB是由运营商部署的, 其位置信息在部署时便已确定, 因此, 不需要 对 eNB进行定位。然而, HeNB是允许由用户部署的,运营商很难确定 HeNB的部署位置 , 这样, 运营商便很难掌握 HeNB的具体分布情况, 从而难以对 HeNB进行有效管理。 发明内容

具体实施方式
本发明实施例中, 为了令 LTE 系统中的 HeNB具有定位相关功能, 重新设计了针对 HeNB的定位流程。 由于 HeNB无法通过空口 (即无线接口 , S 1接口和 X2接口均属于有 线接口)与其他 HeNB或 eNB进行交互,因此,本发明实施例中, HeNB需要通过与 E-SMLC 进行信息交互,采用 S 1接口协议来承载定位流程中使用的 LPP消息( LTE定位协议消息), 即将 HeNB当做用户设备来进行定位, 采用用户设备使用的定位协议。 具体为:
HeNB基于 S 1接口将定位请求消息发往定位服务器 (即 E-SMLC ), 并根据 E-SMLC
的指示进行定位测量, 将定位测量结果发往 E-SMLC, 令 E-SMLC根据该定位测量结果针 对本 HeNB进行定位, 以及基于 S 1接口接收来自于 E-SMLC的定位响应消息, 该定位响 应消息中携带 E-SMLC针对 HeNB进行定位后获得的位置信息,并根据该位置信息确定本 HeNB的物理位置。
相应的, E-SMLC接收 HeNB基于 S 1接口发送的定位请求消息, 指示 HeNB进行定 位测量, 并接收 HeNB返回的定位测量结果, 以及根据该定位测量结果针对所述 HeNB进 行定位, 并基于 S1接口将定位响应消息发往 HeNB , 该定位响应消息中携带 E-SMLC针 对 HeNB进行定位后获得的位置信息,令 HeNB根据接收的位置信息确定该 HeNB的物理 位置。
本发明实施例中, HeNB和 E-SMLC之间交互的 LPP ( LTE定位协议)消息均通过
MME透传, 参阅图 3所示, 针对 HeNB、 MME和 E-SMLC定义了如下的协议栈:
在 HeNB和 MME进行通信时,两者定义的协议栈包含 Ll、 L2、 IP屋、 SCTP层、 Sl-AP 层, 而 MME和 E-SMLC进行通信时, 两者定义的协议栈包含 LI、 L2、 IP层、 SCTP层和 LCS-AP层;如图 1所示, eNB和 E-SMLC之间通过 LPP协议进行通信, S1为 eNB和 MME 之间采用的接口, SLs为 MME和 E-SMLC之间釆用的接口。 根据图 3可以看出, 本实施 例中, HENB与 E-SMLC之间采用 LPP消息进行定位, LPP消息通过 S1-AP承载, 对于 MME而言, LPP消息是透明传输的。
基于上述技术方案, 参阅图 4所示, 本发明实施例中, 对 HeNB进行定位的详细流程 如下:
步骤 401: HeNB基于 S 1接口向 MME发送定位请求消息。
本实施例中 HeNB向 MME发送的定位请求消息, 是符合 S1接口协议的新定义的消 息, 参阅表 1所示, 其消息格式可以设置为如下形式:
表 1
在本发明实施例中, 如表 1所示的定位请求消息是由 S1-AP承载的, 即是一条 S1-AP 消息。
在 HeNB发送的定位请求消息中, 一般携带有 HeNB的标识, MME可以根据 HeNB 的标识, 为 HeNB选择相应的 E-SMLC, 并分配 Rounting ID。
步骤 402: MME基于 SLs接口向选定的 E-SMLC转发定位请求消息。
MME向 E-SMLC转发定位请求消息中携带有分配的 Rounting ID, 或者, 携带 HeNB
的标识, HeNB的标识可以令 E-SMLC在内部进行记录以便和其他 UE分开, 为可选项。 步骤 403: E-SMLC 基于 LPP 协议向 HeNB 发送能力查询请求消息, 即 RequestCapabilitieSo
本实施例中, E-SMLC发往 HeNB的能力查询请求消息可以通过 SLs接口以及 S1接 口透传, 用于向 HeNB获取其能力信息, 即 MME接收到 E-SMLC通过 SLs接口发送的基 于 LPP协议的能力查询消息时, 通过 S1接口透传转发至 He B。 后续流程中 E-SMLC和 HeNB之间交互的下行 LPP消息均是采用此种方式透传, 将不再赘述。
其中, 所谓能力信息用于表示 HeNB可以支持哪些定位方式, 例如, HeNB的能力信 息表示 HeNB可以支持信号到达观察时间差( Observed Time Difference Of Arrival, OTDO A ) 定位方法、 E-CID定位方法(Enhanced Cell-ID positioning method ), 基于小区标识的定位 方法)、 辅助全球导航卫星系统( Assisted-GNSS , A-GNSS )定位方法等等。
步驟 404: HeNB基于 LPP协议发送能力查询响应消息, 该消息中携带有 HeNB的能 力信息。
本实施例中, HeNB发往 E-SMLC的能力查询响应消息可以通过 S1接口以及 SLs接 口透传, 用于向 E-SMLC发送 HeNB的能力信息, 即 MME接收到 HeNB通过 S 1接口发 送的能力查询响应消息时, 通过 SLs接口透传转发至 E-SMLC, 以辅助完成定位流程, 后 续流程中 HeNB和 E-SMLC之间交互的上行 LPP消息均是采用此种方式透传,将不再赘述。
步骤 405: E-SMLC根据 HeNB的能力信息选择相应的定位方式。
例如,假设 HeNB的能力信息表示 HeNB可以支持 OTDOA定位方法;相应的, E-SMLC 选择的定位方式为 OTDOA定位方法。
步骤 406: E-SMLC基于 LPP协议向 HeNB发送定位辅助数据。
本实施例中,假设 E-SMLC基于 LPP协议向 HeNB发送用于实施 OTDOA定位方法的 定位辅助数据, 如, OTDOA小区列表, 该 OTDOA小区列表用于通知 HeNB需要进行定 位测量的小区的定位参考符号 (PRS )信息、 参考小区等信息。 所谓参考小区即是指用于 定位测量的时间基准小区, 也就是以参考小区的时间作为基准, 将其他小区的信号到达时 间和参考小区的相应时间进行比较。
其中, E-SMLC使用的基于 LPP 协议的消息可以是已有的用于提供定位辅助数据 ProvideAssistanceData消息, 也可以是新定义的 LPP消息,关于新定义的 LPP消息, 在后续 实施例中将作出详细介绍。
步骤 407: E-SMLC基于 LPP协议向 HeNB发送位置信息请求消息, 即
RequestLocationlnformatio
E-SMLC基于 LPP协议向 HeNB发送的位置信息请求消息,也可以视为通知 HeNB 进行定位测量的指示消息, HeNB接收到位置信息请求消息后, 会根据之前接收的定位辅
助数据对自身进行定位测量。
步驟 408: HeNB根据 E-SMLC发送的定位辅助数据进行相应的定位测量,获得 HeNB 的定位测量结果, 再基于 LPP 协议向 E-SMLC 发送位置信息响应消息, 即 ProvideLocationlnformation , 该消息中携带有 HeNB的定位测量结果。
本实施例中, 所谓的定位测量结果主要包含 HeNB测量的各个被测小区的信号到达时 间相对于参考小区的信号到达时间的偏差, 以及参考小区时间等等。
步骤 409: E-SMLC根据 HeNB上 4艮的定位测量结果对 HeNB进行定位, 获得 HeNB 的位置信息。
本实施例中, HeNB的位置信息是指 HeNB的具体物理位置, 包含但不限于以下参数 中的至少一种: HeNB的经度、 纬度、 高度等等。
在执行步骤 409时, E-SMLC知道每个被测小区的地理位置信息, 每个被测小区在同 一个时刻发出信号, HeNB测量各个被测小区的信号到达该 HeNB时的时间偏差, E-SMLC 根据时间差可以算出距离差, 进而得到 HeNB与各个被测小区的相对位置, 再根据各被测 小区的地理位置信息, 获得 HeNB的地理位置信息。
步骤 410: E-SMLC基于 SLs接口向 MME发送携带位置信息的定位响应消息。
E-SMLC可以保存 HeNB的位置信息, 以便在后续流程中辅助用户设备进行定位, 即 基于在 HeNB的位置信息,对 HeNB下的普通用户设备进行定位计算,或者也可以将 HeNB 作为邻小区, 辅助其他小区下的普通用户设备的定位计算, 在此不再赘述。
步骤 411 : MME基于 S1接口向 HeNB转发定位响应消息, 用以通知 HeNB定位流程 已结束, 网络侧已获得 HeNB的位置信息。
本实施例中, MME在转发的定位响应消息中, 将网络侧获得的位置信息通知 He B。 与步骤 401同理, 本实施例中 MME向 HeNB发送的定位响应消息, 也可以是符合 S1 接口协议的新定义的消息, 其消息格式可以设置为表 1所示的格式。
步骤 412: HeNB基于 S 1接口向 MME发送释放定位通知消息, 用于通知 MME释放 与本次定位流程相关的定位上下文信息( context )。
本实施例中, HENB在不需要继续进行定位的情况下, 会向 MME发送释放定位通知 消息, 该释放定位通知消息中可以携带 HeNB的标识, 或者 Rounting ID, 用以通知 MME 释放相关的定位上下文信息。
与步骤 401同理, 本实施例中 HeNB向 MME发送的释放定位通知消息, 也可以是符 合 S1接口协议的新定义的消息, 其消息格式可以设置为表 1所示的格式。
在上述实施例的步驟 403、 步骤 404、 步骤 406、 步骤 407和步骤 408中, E-SMLC与 HeNB之间交互的基于 LPP协议的各上下行消息, 可以釆用新定义的 LPP消息, 参阅图 5 和图 6所示, 其中, 图 5中记录的 DOWNLINK LPP TRANSPORT消息(下行链路 LPP传
输消息)是从 E-SMLC发给 HeNB的下行的 LPP消息,如 , 步骤 403中的能力查询请求消 息, 步驟 406中发送的携带定位辅助数据的消息, 步驟 407中发送的位置信息请求消息; 而图 6中记录的 UPLINK LPP TRANSPORT (上行链路 LPP传输消息)是从 HeNB发给 E-SMLC的上行的 LPP消息, 如, 步骤 404中发送的能力查询响应消息, 步骤 408中发送 的位置信息响应消息。
本实施例中,基于 LPP协议的各上下行消息可以采用以下消息格式,具体如表 2所示:
表 2
如表 2所示, HeNB ID为可选信息,也可以用 EUTRAN全球小区标识( EUTRAN Cell Global Identity, ECGI; EUTRAN, Evolved UMTS Terrestrial Radio Access Network, 演进的 UMTS陆地无线接入网; UMTS , Universal Mobile TelecommunicationSystem, 通用移动通 信系统)替代。
即将 S1协议的消息中增加 LPP协议的传输容器 /通道以及部分非接入层(Non Access Stratum, NAS )协议的消息内容, 达到与定位服务器之间交互信息, 并对家庭基站自身进 行定位的目的。
从上述实施例可以看出, 本发明实施例中, 对 HeNB进行物理位置定位时, 各网元执 行的具体操作为:
首先, 对于 HeNB而言,
HeNB开机后, 通过基于 S1接口向 MME发送新定义的定位请求消息,在定位请求消 息中, 可以携带 HeNB的标识, 也可以携带该 HeNB能够搜索到的信号强度达到预设门限 值的宏小区信息; 接着, HeNB根据 E-SMLC基于 LPP协议发送的能力查询请求消息, 向 E-SMLC返回自身的能力信息,并根据 E-SMLC下发的定位辅助数据及基于 LPP协议的位 置信息请求消息,将自身经定位测量获得的位置信息采用基于 LPP协议的位置信息响应消 息发往 E-SMLC, 其中, 在根据 E-SMLC下发的定位辅助数据进行定位测量时, HeNB并 不像用户设备一样会驻留在某个服务小区下,而 LPP协议中规定在进行定位测量时需上报 服务小区的信息, 则本实施例中, HeNB可以采用自身搜索到的信号最强的宏小区的信息 替代服务小区的信息,最后, HeNB接收到 MME基于 S1接口发送的来自于 E-SMLC的位 置信息时, 保存该位置信息从而完成自身位置的定位, 进一步地, HeNB还需要通过基于
S I接口的消息通知 MME释放相关的定位上下文信息,以及将自身的位置信息上报给操作 维护( Operation and Maintenance, OM ) 实体, 不同的实体都有各自的 OM, 可以认为是 运营商的管理平台。
其次, 对于 MME而言,
MME接收到 HeNB基于 S1接口发送的定位请求消息, 分配相应的 Rounting ID , 并 基于 SLs接口将定位请求消息转发给 E-SMLC , 可以携带 HeNB 的标识; MME接收到 E-SMLC通过 SLs接口发送的各类下行 LPP消息时, 通过 S 1接口透传转发至 HeNB, 以 及在接收到 HeNB通过 S1接口发送的各类上行 LPP消息时, 通过 SLs接口透传转发至 E-SMLC, 以辅助完成定位流程, 最后, MME通过 SLs接口到 E-SMLC发送的携带针对 HeNB的位置信息的定位响应消息时,保存该位置信息,并将该位置信息通过基于 S 1接口 新定义的定位响应消息发送至 HeNB息, 以及在接收到 HeNB通过基于 S 1接口新定义的 释放定位通知消息时, 释放针对该 HeNB的定位上下文信息, 以及释放该 HeNB的标识。
再次, 针对 E-SMLC而言,
E-SMLC接收到来自于 HeNB由 MME转发的定位请求消息后 , 保存 MME为 HeNB 分配的 Rounting ID , 若存在 HeNB的标识, 则也一并保存; 接着, E-SMLC通过基于 LPP 协议的能力查询请求消息请求 HeNB上 4艮其定位能力,在通过基于 LPP协议的能力查询响 应消息接收到 HeNB的能力信息后, 根据该能力信息为 HeNB选择相适应的定位方法, 并 基于 LPP协议向 HeNB提供相应的定位辅助数据, 并基于 LPP协议向 HeNB发送位置信 息请求消息, 并通过基于 LPP协议的位置信息响应消息,接收 HeNB发送的基于定位辅助 数据进行定位测量后获得的 HeNB的位置信息,以及基于该位置信息对 HeNB进行物理位 置定位, 获得位置信息, 并将该位置信息通过 SLs接口发往 MME进行保存, 其中, 若 E-SMLC保存有 HeNB的标识, 则可以保存其相应的位置信息, 用于后续的用户设备辅助 定位。
本实施例中, 较佳的, 为了避免 HeNB与 HeNB GW相连再接入到 MME后, MME 无法识别 HeNB ,则 HeNB在采用新定义的 S 1消息时,可以携带 HeNB自身的标识加以区 分。
基于同一发明构思, 本发明实施例中还提供了一种 HeNB和 E-SMLC, 由于这些设备 解决问题的原理与本发明实施例对 HeNB进行定位的方法相似, 因此这些设备的实施可以 参见方法的实施, 重复之处不再赘述。
基于上述实施例, 参阅图 7所示, 本发明实施例中, HeNB包含发送单元 70、 测量单 元 Ί 1和接收单元 72 , 其中,
发送单元 70, 用于基于 S 1接口将定位请求消息发往 E-SMLC;
测量单元 71 ,用于根据 E-SMLC的指示进行定位测量,并将定位测量结果通过发送单
元 70发往 E-SMLC , 令 E-SMLC根据该定位测量结果针对本 HeNB进行定位; 接收单元, 用于基于 S 1接口接收来自于 E-SMLC的定位响应消息, 该定位响应消息 中携带 E-SMLC针对本 HeNB进行定位后获得的位置信息,并根据该位置信息确定本 HeNB 的物理位置。
参阅图 8所示, 本发明实施例中, E-SMLC包括接收单元 80、 定位单元 81和发送单 元 82 , 其中,
接收单元 80, 用于接收 HeNB基于 S 1接口发送的定位请求消息;
定位单元 81 , 用于指示 HeNB进行定位测量, 并通过所述接收单元 80接收 HeNB返 回的定位测量结果, 以及根据该定位测量结果针对所述 HeNB进行定位;
发送单元 82 , 用于基于 S 1接口将定位响应消息发往 HeNB , 该定位响应消息中携带 本 E-SMLC针对 HeNB进行定位后获得的位置信息,令 HeNB根据接收的位置信息确定该 HeNB的物理位置。
综上所述,本发明实施例中 , HeNB基于 S 1接口将定位请求消息发往 E-SMLC , E-SMLC 指示 HeNB进行定位测量, 并根据 HeNB返回的定位测量结果针对所述 HeNB进行定位, 获得 HeNB的位置信息,而所述 HeNB基于 S 1接口接收来自于 E-SMLC的定位响应消息, 并根据该定位响应消息中携带所述位置信息确定本 HeNB 的物理位置, 这样, 便基于 S 1 接口协议及 LPP协议重新定义了 HeNB和 E-SMLC之间的交互流程,从而实现了网络侧对 HeNB的准确定位,令运营商可以及时掌握 HeNB的具体分布情况,进而实施有效的管理, 确保了系统的性能。
