Description

位置服务中识别用户的方法和系统
技术领域 本发明涉及通信领域,更具体地涉及位置服务中识别用户的方法和系统。
背景技术
参考图 1所示,现有技术的全球微波互联接入(Worldwide Interoperability for Microwave Access, WiMAX ) 系统一般由三部分组成: 终端、 接入业务 网络 ( Access Service Network, ASN ) 和连接业务网络 ( Connect Service Network, CSN ) 。
ASN主要执行如下的功能: 完成 WiMAX终端的二层(L2 )连接、 传递 认证授权计费 ( Authentication Authorization Accounting, AAA ) 消息到归属 CSN ( Home-CSN, H-CSN ) 、 网络服务运营商 ( Network Service Provider, NSP ) 的网络选择与发现、 为 WiMAX终端的三层(L3 )连接提供中继、 无 线资源管理、 以及 ASN与 CSN之间隧道维护。 在移动的场景下, ASN还需 要支持如下的功能: ASN 锚定的移动性管理 (ASN Anchored Mobility Management, ASN Anchored MM ) 、 CSN锚定的移动性管理( CSN Anchored MM ) 、 寻呼和空闲模式( Idle Mode )操作。
ASN还用于管理 IEEE 802.16空中接口, 为 WiMAX终端用户提供无线 接入。 ASN至少由一个基站 (Base Station, BS )和一个 ASN 网关 (ASN Gateway, ASN-GW )组成, 可以包含单个 ASN-GW或多个 ASN-GW, 参考 模型如图 2和图 3所示。 ASN在 R1参考点与移动站( Mobile Station, MS ) 互通, 在 R3参考点与 CSN互通, 在 R4参考点与另一个 ASN互通。 管理 ASN的运营商称为网络接入运营商 (Network Access Provider, NAP ) 。 CSN是一套网络功能的组合, CSN 可以由移动 IP 的家乡代理(Home
Agent, HA ) 、 AAA代理或服务器( AAA Proxy/Server ) 、 计费服务器、 以 及互连网关设备等组成。 管理 CSN的运营商称为 NSP。 CSN主要提供如下的功能: 终端用户会话连接、 终端的 IP地址分配、 Internet接入、 AAA代理或服务器、终端用户的策略及许可控制、 ASN与 CSN 之间的隧道维护、 终端用户计费和结算、 CSN间的漫游、 CSN间的移动性管 理和 WiMAX业务。 WiMAX网络中的位置服务( Location-Based Service, LBS )参考模型如 图 4所示。 LBS架构是和 WiMAX网络参考模型共存的功能模型。 LBS架构 支持控制面位置测量、用户面位置测量、以及控制面和用户面混合位置测量。 位置服务器 (Location Server, LS )位于 CSN, 接收位置请求者 (Location Requester, LR )的位置请求, 并触发位置测量流程。 在漫游场景中, 拜访位 置服务器( Visit LS, vLS )位于 vCSN中, 归属位置服务器( Home LS, hLS ) 位于 hCSN中。位置控制器( Location Controller, LC )位于服务 ASN( Serving ASN ) 的 AGW, LC收到 LS的位置测量请求后, 触发位置相关的测量, 并 收集位置相关数据。 位置代理(Location Agent, LA )位于 BS, 负责测量、 收集和报告测量数据给 LC。 LR是 MS位置信息的请求者,可以位于 WiMAX 网络内或 WiMAX网络外, 如, 可以是 MS或者外部的应用服务器。 当 LR 是外部的应用服务器时, LR通过 U1参考点和 LS互通。
WiMAX网络中的位置服务有两种应用模型: MS管理位置和网络管理位 置。 MS管理位置指 MS测量、 计算和使用位置信息。 MS从 BS的广播消息 中获得 BS的位置信息, 从而计算 MS的位置信息, 不涉及其他网元识别用 户的场景。 而网络管理位置中, 在触发、 测定或报告位置时需要途径的各个 网元都能够识别用户。 网络参与位置判断和管理过程, 又有三类: 控制面位置测量, 用户面位 置测量, 及控制面和用户面混合位置测量。 控制面位置测量是 LS通过 R3参考点从 LC获得测量, 并在 LS执行位 置判断。 LR可以是 MS或外部的第三方实体。 用户面位置测量中, 由 MS和 LS通过 R2参考点传递测量、 全球定位系 统(Global Positioning System, GPS )辅助信息和接入网络信息用于位置判 断。 位置判断可以由 LS完成, 或者由 MS完成。 MS或者外部实体均可向 LS发起位置请求。在用户面位置测量流程中, L S还会向锚定鉴权器( Anchor Authenticator )获取一些信息, 如基站识别码 ( Base Station Identity Code, BSID ) 。 混合控制面和用户面的位置测量中, LS可以同时支持用户面和控制面判 断机制, 综合控制面和用户面测量的信息为 MS提供最终的位置判断。 控制面测量涉及用户处于正常(Normal ) 态时的控制面测量和用户处于 Idle态时的控制面测量。 用户处于正常态时的控制面测量和用户处于 Idle态 时的控制面测量的区别是在 Idle态下, 需要把用户寻呼起来, 再继续测量流 程。 用户的位置信息作为用户的隐私应受保护。 AAA和 LS对 LR执行认证 和授权, 以保护目标 MS的隐私。 在认证授权过程中, LS从 AAA获得授权 及目标 MS的信息。 如图 5所示。 以控制面的位置测量流程为例, LS获得 AAA的 4受权后, 向 Anchor Authenticator发起该目标 MS的位置获取流程, Anchor Authenticator通知 LC获取 MS的位置信息, LC和 BS/LAs、 MS交互 获取 MS的位置信息, 再传递给 LS。 如图 6和图 7所示。
图 5是 WiMAX网络位置服务基于 Radius的认证授权流程,简要概述如 下:
步骤 501 : LR 向 LS 发送位置请求消息, 携带信息包括 LR 的标识 ( Identifier )和目标 MS的 Identifier (用户接入时的外层网络接入标识( Outer Network Access Identifier, Outer NAI ) ) 。 LR可以是外部实体或 MS。 LR 可以是一次性请求目标 MS的位置, 也可以是周期性请求目标 MS的位置。 步骤 502: LS向 AAA发送远程用户拨号认证系统( Remote Authentication Dial In User Service, RADIUS )接入请求( RADIUS Access-Request ) 消息, 携带从 LR收到的属性, 并通知 AAA对 LR进行认证, 决定是否授权 LR使 用该月良务, 并定位目标 MS。 步骤 503: AAA对 LR认证通过,向 LS返回 RADIUS接入响应( RADIUS Access-Accept )消息,携带信息包括: Anchor Authenticator和 MS的 IP地址。 步骤 504: LS发起位置测量流程。
图 6是 Normal态下基于 MS/BS扫描测量的控制面位置测量流程, 简要 概述如下: 步骤 601: LR向 LS发送位置请求( Location Request ) 消息, 触发位置 测量流程; LR可以是外部实体或者 MS。 LR可以是一次性请求目标 MS的 位置, 也可以是周期性请求目标 MS的位置。 步骤 602: LS和 AAA执行对 LR的认证和授权流程, 如图 5所示。 步骤 603: LS向 Anchor Authenticator发送 RADIUS授权改变( Change of Authorization, Co A ) Request才艮文, 包含测量请求( Measurement Request ) 消息。 步骤 604: Anchor Authenticator收到包含测量请求( Measurement Request ) 消息的 Co A Request才艮文, 向 LS回 Radius CoA确认 ( Acknowledgement, ACK )才艮文, 包含测量请求确认 ( Measurement Request Acknowledgement ) 消息。 步骤 605: Anchor Authenticator向 LC发送 R4 Measurement Request消息 请求位置测量; Anchor Authenticator和 LC可以位于相同的 ASN, 在发生切 换后, Anchor Authenticator和 LC也可以位于不同 ASN , J¾时, R4 Measurement Request消息需要经过 Anchor Authenticator所在的 ASN和 LC所在的 ASN 之间的 ASN对 R4 Measurement Request消息中转至 LC。 步骤 606: LC向 Anchor Authenticator返回 R4测量请求确认( Measurement Request ACK ) 消息。 步骤 607: LC向 Serving BS发送 R6 Measurement Request消息。 步骤 608: Serving BS向 LC返回 R6 Measurement Request ACK ) 消息。 步骤 609: Serving BS及邻接的 BS和 MS间交互, 执行位置扫描和测量 计算, 可以在 MS计算也可以在 BS计算。 步骤 610: Serving BS向 LC发送 R6测量响应 ( Measurement Response ) 消息。 步骤 611: LC向 Serving BS返回 R6测量响应确认( Measurement Response ACK ) 消息。 步骤 612: LC将测量报告上报给 LS , LC可以直接发送给 LS, 或者通 过 Anchor Authenticator及中间的 ASN发送测量报告给 LS。 步骤 613: LS收到测量报告后,向 LR返回位置响应(Location Response ) 消息, LR可以是外部实体或者 MS。如果 LR需要周期性地获取 MS的位置, 则 LS需要周期性地触发 LBS流程 (从步骤 603至步骤 613 ) 。
图 7是 Normal态下基于 BSID的控制面位置测量流程, 简要概述如下: 步骤 701 : LR向 LS发送 Location Request消息, 触发位置测量流程; LR可以是外部实体或者 MS。 LR可以是一次性请求目标 MS的位置, 也可 以是周期性请求目标 MS的位置。
步骤 702: LS和 AAA执行对 LR的认证和授权流程, 如图 5所示。 步骤 703: LS向 Anchor Authenticator发送 RADIUS CoA Request报文, 包含 Measurement Request消息。 步骤 704: Anchor Authenticator收到包含 Measurement Request消息的 CoA Request报文, 向 LS回 RADIUS CoA ACK报文, 包含 Measurement Request Acknowledgement消息。 步骤 705 : Anchor Authenticator收到的测量请求消息仅请求 BSID , Anchor Authenticator直接向 LS发送包含 Measurement Response消息的 Accounting Request报文, 携带 BSID。 步骤 706 : LS 收到包含 Measurement Response 消息的计费请求 ( Accounting Request )才艮文, 向 Anchor Authenticator返回包含 Measurement Response ACK消息的计费响应 ( Accounting Response )报文。 步骤 707: LS向 LR返回 Location Response消息, LR可以是外部实体 或者 MS。 如果 LR需要周期性地获取 MS的位置, 则 LS需要周期性地触发 LBS流程 (从步骤 703至步骤 707 ) 。 在 WiMAX网络的位置服务中, 位置测量流程涉及到 CSN内的 AAA和 LS网元, 及 ASN内的 BS、 Anchor Authenticator和 LC网元, 这些网元都需 要能够识别目标 MS, 才能进一步对该用户提供位置测量服务。 上述的控制 面位置测量流程中, ASN内的 BS和 LC交互的 R6 Measurement Request消 息 , 及 Anchor Authenticator和 LC交互的 R4 Measurement Request消息中均 携带了目标 MS的唯一标识。 而在 LS通知 Anchor Authenticator位置测量请 求的 CoA Request 消息中则没有携带 MS 的唯一标识, 而是携带了用户的 Outer-NAI。 如果期望根据 Outer-NAI来识别目标 MS, 在 MS接入 WiMAX 网络后保持该 Outer-NAI不变的场景下是可行的。 然而, MS在重鉴权流程中, Outer-NAI是可以改变的。 LS无法获知 MS 是否执行了重鉴权流程, 也无法实时获得 MS最新的 Outer-NAI, 因此, 在 LS 周期性获取目标 MS 位置的场景中, LS 始终以首次向 AAA 获取的 Outer-NAI来标识目标 MS, 而 Anchor Authenticator是以重鉴权后用户最新 的 Outer-NAI来标识用户, 此时, LS和 Anchor Authenticator用以标识用户 的信息不一致。 因此, 在上述场景下, Anchor Authenticator 在收到包含 Measurement Request消息的 CoA Request才艮文时, 会查询用户失败, 例如以 下两种情况: 一个是 Anchor Authenticator找不到需要被定位的终端, 这是因 为该终端的 Outer-NAI改变了, 因此也无法进一步地向 LC、 BS发起位置测 量流程; 另一个是 Anchor Authenticator可能会找错被定位的终端, 这是因为 原来终端的 Outer-NAI改变以后, 可能会有其他终端占用该 Outer-NAI。 前 一种情况将导致定位流程无法继续; 后一种情况会导致定位错误的终端。 无 论哪种情况, 都会导致定位流程无法正确执行, 造成用户满意度下降, 不利 于业务开展。
发明内容 本发明提供了一种位置服务中识别用户的方法和系统, 以解决如何能够 准确识别用户, 使得定位流程正确执行, 提高用户满意度的问题。 为了解决上述问题, 本发明提供了一种位置服务中识别用户的方法, 该 方法包括: 位置服务器接收位置请求者的位置请求, 向锚定鉴权器发送测量请求消 息, 所述测量请求消息中携带待定位终端的唯一标识; 以及 所述锚定鉴权器根据所述测量请求消息中携带的所述唯一标识, 识别所 述待定位终端。 上述方法中, 所述位置请求为一次性位置请求或周期性位置请求。 所述位置服务器向所述锚定鉴权器发送测量请求消息的步骤之前, 所述 方法还包括: 所述位置服务器与所述 AAA交互进行认证授权, 在所述认证授权过程 中, 所述位置服务器从所述 AAA获取所述待定位终端的唯一标识。 所述方法还包括: 所述 AAA在所述待定位终端的初始接入过程中获取 所述待定位终端的唯一标识。 所述方法还包括: 所述锚定鉴权器识别所述待定位终端后, 发起对所述 待定位终端的位置测量过程。 为了解决上述问题, 本发明还提供了一种位置服务中识别用户的系统, 所述系统包括: 位置服务器和锚定鉴权器, 其中: 所述位置服务器设置为: 接收位置请求者的位置请求, 向锚定鉴权器发 送测量请求消息, 所述测量请求消息中携带待定位终端的唯一标识; 所述锚定鉴权器设置为:根据所述测量请求消息中携带的所述唯一标识 , 识别所述待定位终端。 上述系统中, 所述位置请求为一次性位置请求或周期性位置请求。 上述系统中, 所述位置服务器还设置为: 向所述锚定鉴权器发送测量请 求消息前, 与所述 AAA交互进行认证授权, 在所述认证授权过程中, 从所 述 AAA获取所述待定位终端的唯一标识。 上述系统中, 所述锚定鉴权器还设置为: 识别所述待定位终端后, 发起 对所述待定位终端的位置测量过程。 为了解决上述问题, 本发明还提供了一种位置服务中识别用户的方法, 所述方法包括: 在位置服务器周期性获取待定位终端的位置信息的过程中, AAA在所述 待定位终端的外层网络接入标识(Outer-NAI ) 改变时, 将改变的 Outer-NAI 通知所述位置服务器; 在每次获取所述待定位终端的位置信息过程中, 所述位置服务器向锚定 鉴权器发送测量请求消息, 所述测量请求消息中携带待定位终端的外层网络 接入标识; 以及 所述锚定鉴权器根据所述外层网络接入标识, 识别所述待定位终端。 该方法中, 在所述位置服务器周期性获取待定位终端的位置信息的过程中, AAA在 所述待定位终端的 Outer-NAI改变时, 将改变的 Outer-NAI通知所述位置服 务器的步骤包括: 所述位置服务器接收到周期性位置请求时, 发送开始周期性定位指示信 息给所述 AAA, 指示开始对所述待定位终端进行周期性定位; 以及 所述 AAA接收到所述开始周期性定位指示信息后, 在所述待定位终端 的 Outer-NAI改变时, 将改变的 Outer-NAI通知所述位置服务器。 所述方法还包括, 所述位置服务器在不需要周期性获取所述待定位终端的位置信息时, 发 送停止周期性定位指示信息给所述 AAA; 以及 所述 AAA接收到所述停止周期性定位指示信息后, 停止在所述待定位 终端的 Outer-NAI改变时, 将改变的 Outer-NAI通知所述位置服务器。 为了解决上述问题, 本发明还提供了一种位置服务中识别用户的系统, 所述系统包括: 认证授权计费 (AAA ) 、 位置服务器和锚定鉴权器, 其中: 所述 AAA设置为: 在所述位置服务器周期性获取待定位终端的位置信 息的过程中, 当所述待定位终端的外层网络接入标识(Outer-NAI ) 改变时, 将改变的 Outer-NAI通知所述位置服务器; 所述位置服务器设置为: 在每次获取待定位终端的位置信息过程中, 向 锚定鉴权器发送测量请求消息, 所述测量请求消息中携带待定位终端的外层 网络接入标识; 所述锚定鉴权器设置为: 根据所述外层网络接入标识, 识别所述待定位 终端。 该系统中, 所述位置服务器还设置为: 接收到周期性位置请求时, 发送开始周期性 定位指示信息给所述 AAA, 指示开始对所述待定位终端进行周期性定位; 所述 AAA是设置为按如下方式将改变的 Outer-NAI通知所述位置服务 器:接收到所述开始周期性定位指示信息后,在所述待定位终端的 Outer-NAI 改变时, 将改变的 Outer-NAI通知所述位置服务器。 该系统中, 所述位置服务器还设置为: 在不需要周期性获取所述待定位终端的位置 信息时, 发送停止周期性定位指示信息给所述 AAA; 所述 AAA还设置为: 接收到所述停止周期性定位指示信息后, 停止在 所述待定位终端的 Outer-NAI改变时, 将改变的 Outer-NAI通知所述位置服 务器。 本发明所述方法在测量请求消息中携带待定位终端的唯一标识, 由于该 唯一标识保持不变, 因此, 根据该唯一标识能够准确找到需要定位的终端。 本发明另一方法及时将改变的 Outer NAI发送给位置服务器, 同样达到了准 确找到需要定位的终端的目的。 通过釆用本发明, Anchor Authenticator可以 从 LS获得目标 MS的准确唯一标识, 从而能使对终端的定位流程正确执行。

本发明的较佳实施方式 为使本发明的目的、 技术方案和优点更加清楚明白, 下文中将结合附图 对本发明的实施例进行详细说明。 需要说明的是, 在不冲突的情况下, 本申 请中的实施例及实施例中的特征可以相互任意组合。 本发明实施例中, 在 LS发送给 Anchor Authenticator的测量请求消息中 携带目标 MS (待定位终端) 的唯一标识, 由于该唯一标识不会改变, 所以 Anchor Authenticator可以准确查找到对应的终端; 或者, 由 AAA在目标 MS 的 Outer NAI时, 及时将改变的 Outer NAI同步给 LS, 使得 LS和 Anchor Authenticator处的目标 MS的 Outer NAI同步, 从而 Anchor Authenticator可 以根据 Outer NAI准确查找到对应的终端。 本发明实施例提供一种位置服务中识别用户的方法, 该方法包括: 位置服务器接收位置请求者的位置请求, 向锚定鉴权器发送测量请求消 息, 所述测量请求消息中携带待定位终端的唯一标识, 所述锚定鉴权器根据 所述测量请求消息中携带的所述唯一标识, 识别所述待定位终端, 从而实现 准确识别用户。 所述锚定鉴权器识别所述待定位终端后, 发起对所述待定位 终端的位置测量过程。 上述方法中, 所述位置请求为一次性位置请求或周期性位置请求。 上述方法中, 所述位置服务器向所述锚定鉴权器发送测量请求消息前, 还与所述 AAA交互进行认证授权, 在所述认证授权过程中, 所述位置服务 器从所述 AAA获取所述待定位终端的唯一标识。 所述唯一标识可以是待定 位终端的媒体访问控制 (Medium Access Control, MAC )地址, 也可是其他 可唯一标识终端的信息。 所述位置服务器也可能从位置请求者处获取待定位 终端的唯一标识。 上述方法中, 所述 AAA在所述待定位终端的初始接入过程中获取所述 待定位终端的唯一标识。 本发明另一实施例还提供一种位置服务中准确识别用户的方法, 该方法 包括: 在位置服务器周期性获取待定位终端的位置信息的过程中, AAA在所述 待定位终端的外层网络接入标识(Outer-NAI ) 改变时, 将改变的 Outer-NAI 通知所述 LS; 以及 在每次获取所述待定位终端的位置信息过程中, 所述位置服务器向锚定 鉴权器发送测量请求消息, 所述测量请求消息中携带待定位终端的外层网络 接入标识, 所述锚定鉴权器根据所述外层网络接入标识, 识别所述待定位终 端, 从而实现准确识别用户。 该方法中, 所述位置服务器接收到周期性位置请求时, 发送开始周期性 定位指示信息给所述 AAA,指示开始对所述待定位终端进行周期性定位; 以 及 所述 AAA接收到所述开始周期性定位指示信息后, 在所述待定位终端 的 Outer-NAI改变时, 将改变的 Outer-NAI通知所述位置服务器。 所述位置服务器在不需要周期性获取所述待定位终端的位置信息时, 发 送停止周期性定位指示信息给所述 AAA; 所述 AAA接收到所述停止周期性定位指示信息后, 停止在所述待定位 终端的 Outer-NAI改变时, 将改变的 Outer-NAI通知所述位置服务器。 具体地, 所述开始周期性定位指示信息或停止周期性定位指示信息可通 过周期性定位标识字段携带。 LS在到 AAA认证时通过该周期性定位标识字 段携带开始周期性定位指示信息。
以下结合附图对本发明的优选实施例进行说明, 应当理解, 此处所描述 的优选实施例仅用于说明和解释本发明, 并不用于限定本发明。 下面的实施例中的位置测量方法以控制面测量流程为例, 并基于 RADIUS协议用于用户标识的下发, 在实际的环境中还可能存在别的类型的 协议可用于用户标识的下发, 如 Diameter等。 这些实施例中的方法也同样适 用于用户面位置测量流程需要 AGW内功能实体参与的场景。 为功能描述清 晰, 这里以 Anchor Authenticator和 LC分开的方式进行描述, 实现时 Anchor Authenticator和 LC也可以合一。 Anchor Authenticator和 LC合一时, 将省略 Anchor Authenticator和 LC之间的 R4消息。 为了使图简明扼要, 图中忽略了对关键参数传递无影响的转发网元及相 关场景, 如漫游, 切换以及 Idle等, 但是这些在实际环境中是可以存在的。
