Description

预置流分类器的建立方法及其系统和用户终端
本申请要求于 2006 年 7 月 11 日提交中国专利局、 申请号为 200610106528.2、 发明名称为"预置流分类器的建立方法及其系统和用户终端" 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
本发明涉及移动通信领域, 特别涉及微波接入全球互通 (Worldwide Interoperability for Microwave Access , 简称" WiMAX" )系统中的预置流分类器 建立技术。
背景技术
近年来, 以本地多 点分配系 统 ( Local Multipoint Distribution
System/Service , 简称" LMDS" )、 波多点分配系统 (Microwave Multipoint Distribution System , 简称" MMDS" )、 无线保真度 ( Wireless Fidelity, 简称 "Wi-Fi" )、 WiMAX等技术为代表的宽带无线接入技术成为宽带接入领域的生 力军。
与有线接入方式相比, 这类技术具备启动资金少、 初期投入少、 建设周期 短、 提供服务快速, 发展具备很大灵活性、 可按用户需求动态分配系统资源, 系统维护成本低等诸多优势。 而其高速接入速率, 甚至令一些有线接入技术也 难以企及, 因此为发展宽带数据综合业务提供了可能。
其中, WiMAX技术是一项无线城域网技术, 它是针对微波和毫米波频段 提出的一种新的空中接口标准。
WiMAX用于将无线接入热点连接到互联网, 也可连接公司与家庭等环境 至有线骨干线路。 它可作为线缆和数字用户线(Digital Subscriber Line, 简称 "DSL" )的无线扩展技术, 从而实现无线宽带接入。 将此技术与需要授权或免 授权的微波设备相结合之后, 由于成本较低, 将扩大宽带无线市场, 改善企业 与服务供应商的认知度。
图 1示出了 WiMAX端到端参考模型。 如图可见, WiMAX主要包括用户 站( Subscribe Station, 简称" SS" ) /移动台 ( Mobile Station, 简称" MS" )、 接入 服务网络( Access Service Network ,简称" ASN" )与连接服务网络( Connectivity Service Network, 简称" CSN" )。 ASN定义为为 WiMAX用户终端提供无线接入服务的网络功能集合, ASN 包括 BS和 ASN网关 (ASN GateWay, 简称" ASN-GW" ) 网元, 一个 ASN可 能被多个 CSN共享。
ASN的主要功能包含 BS的功能和 ASN-GW的功能。其中, BS的功能有: 提供 BS和 SS/ MS的 L2 (层二)连接、 无线资源管理、 测量与功率控制和空 口数据的压缩与加密。 ASN-GW的功能有: 为 SS/MS认证、 授权和计费功能 提供代理( proxy )功能;支持网络服务提供商 ( Network Service Provider, NSP ) 的网络发现和选择; 为 SS提供 L3 (层三)信息的中继 (Relay )功能, 如 IP 地址分配。
CSN定义为为 WiMAX用户终端提供 IP连接服务。 CSN主要提供如下功 能: SS/MS的 IP地址分配, Internet接入,验证、授权、计费协议( Authentication, Authorization, Account, 简称" AAA" ) 代理(proxy )或者服务(server ), 基 于用户的授权控制, ASN到 CSN的隧道, WiMAX用户的计费以及运营商之 间的结算, 漫游情况下 CSN之间的隧道, ASN之间的切换, 和各种 WiMAX 服务(如基于位置的业务、 多媒体多播和广播业务、 IP多媒体子系统业务)。
MS/SS为 (移动)用户设备, 用户使用该设备接入 WiMAX网络。
以上对 WiMAX及其网络构架进行了说明,接下来进一步说明 WiMAX网 络中的分类器以及预置流的概念。
在 WiMAX网络中,分类器用于将网络承载的各种业务分类到承载网络的 具体服务流中。 服务流是 WiMAX承载网络服务质量 (Quality of Service, 简称 "Qos")保证的最小操作对象,不同的服务流可以有不同的 QoS保证,分类器可 以根据上层业务不同的 QoS要求, 将其分配到相应的服务流中。
分类器由一系列分类规则组成, 如果承载的是 IP业务, 主要的分类参数 之一就是 IP地址。 例如对于 IPv4数据包, 根据源 /目的 IP地址、 协议类型、 源 /目的传输控制协议( Transmission Control Protocol , 简称" TCP" ) /用户数据 才艮文协议( User Datagram Protocol, 简称" UDP" )端口号就可将特定 IP包分类 到某个具体业务流。 上行业务的分类器在用户终端 (如 MS )上实现, 下行业 务分类器在 BS或 ASN-GW上实现。
用户终端入网后,通常网络侧会根据用户终端与网络服务提供商的签约信 息预先建立好相关的业务通道, 包括建立空口和网络侧相应的承载数据通道, 即预置流。
通过预置流, 用户终端就可使用网络提供的相应业务。 需要指出的是, 承 载在预置流之上的业务也包括 3层(网络层) 的信令传输。
下面对用户终端入网的过程进行具体说明, 根据现有技术, 如图 2所示, 用户终端在入网时, 首先进入步骤 210, 用户终端发起初始入网过程, 在初始 入网成功后, 接着进入步骤 220。
在步骤 220 中, 由 ASN-GW中的相关功能实体根据初始入网阶段 AAA 下发的用户终端预置流配置,发起预置流建立过程,在预置流建立过程中创建 相应的分类器。所建立的分类器包括预置流业务的分类器以及其他业务的分类 器, 主要用于将网络承载的上层业务分类到承载网络的服务流中。 网络承载的 上层业务包括 3层(网络层)及以上层的所有业务和信令。 其中, 上行业务的 分类器的创建在用户终端实现, 下行业务的分类器的创建在 BS 或 ASN-GW 上实现。
在预置流业务建立完成之后, 接着进入步骤 230, 通过已建立的预置流承 载 3 层信令, 为用户终端分配所需的 IP地址。 在 IP地址分配成功后, 由 ASN-GW记录相应用户终端使用的 IP地址。
在实现本发明的过程中,发明人发现现有技术中至少存在如下问题: 用户 终端初始入网后首先发起预置流建立过程,建立预置流业务和相应的预置流分 类器, 再通过已建立的预置流承载 3层信令, 为用户终端分配 IP地址, 按照 这种操作顺序, 在预置流建立过程中建立预置流分类器时, 由于用户终端 IP 地址尚未分配, 使得所建立的预置流分类器的用户终端 IP地址参数空缺, 而 未设置 IP地址的预置流分类器无法正常分流用户终端的预置流业务。 也就是 说, 在实际应用中, 按照上述方案所建立的预置流分类器可能无法正常工作。 发明内容

下面将结合附图对本发明实施例作进一步地详细描述。
本发明实施例在用户终端入网成功后 ,在网络侧和用户终端之间建立用于 承载 3层信令的初始业务通道( Initial Service Flow, 简称" ISF" ) , 通过在该初 始业务通道 载的 3层信令交互为该用户终端分配 IP地址, IP地址分配成功 后, 由网络侧以该 IP地址建立预置流分类器, 并设置预置流分类器的参数。 或者在用户终端入网成功后,先建立预置流分类器并设置其参数; 在为用户终 端进行 IP地址分配成功后, 再根据所分配的 IP地址修改已建立的预置流分类 器中的用户终端 IP地址参数。 在这种方式中, 可以通过已建立的预置流承载 信令, 为所述用户终端分配 IP地址。
下面对本发明第一实施方式的预置流分类器的建立系统进行说明。
本发明实施例的预置流分类器的建立系统包括网络侧的通道建立设备、地 址分配设备、 和分类器建立设备(第一分类器建立设备)。 其中, 网络侧的通 道建立设备用于在用户终端入网成功后 ,在网络侧和该用户终端之间建立用于 承载 3层信令的初始业务通道;网络侧的地址分配设备用于在通道建立设备建 立的初始业务通道上通过 3层信令的交互为用户终端分配 IP地址; 网络侧的 分类器建立设备用于在地址分配设备为用户终端成功分配 IP地址后, 以该 IP 地址建立预置流分类器, 并设置预置流分类器的参数。 网络侧建立的预置流分 类器包括: 上行预置流分类器和 /或下行预置流分类器。 例如, 需要传输双向 业务时, 可以同时建立上行预置流分类器和下行预置流分类器; 需要传输单向 业务(比如上行业务或下行业务), 则只建立上行预置流分类器或下行预置流 分类器。本领域的技术人员应能理解, 本申请所述网络侧建立上行预置流分类 器, 是指网络侧配置上行预置流分类器参数, 并将其下发给终端, 以用于在终 端侧实现上行预置流分类器; 本申请所述网络侧建立下行预置流分类器,是指 网络侧配置下行预置流分类器参数, 以用于在网络侧实现下行预置流分类器。
所述系统还可以包括用户终端 ,用于在所述地址分配设备为所述用户终端 成功分配 IP地址后, 以该 IP地址设置 (即修改)用户终端侧预置流分类器的 参数。
在实际应用中,上述系统中网络侧的通道建立设备可以是 ASN-GW或 BS, 地址分配设备可以是 ASN-GW、 家乡代理(Home Agent, 简称' ΉΑ,,)、 动态 主机控制协议( Dynamic Host Configuration Protocol, 简称" DHCP" )服务器、 AAA服务器中的一个或多个, 分类器建立设备可以是 ASN-GW或 BS。
以上对本实施方式的系统进行了说明,下面对本实施方式预置流分类器的 建立方法进行详细介绍。
如图 3所示, 在步骤 310中, 用户终端发起初始入网过程, 在用户终端成 功入网后, 进入步骤 320。 前述用户终端成功入网是指初始入网过程中鉴权认 证和用户终端与网络侧的能力协商(REG-REQ/REG-RSP , Registration Request/Registration Response)成功。
在步骤 320中, ASN-GW在网络侧和该用户终端之间建立用于承载 3层 信令的初始业务通道。
在建立初始业务通道的过程中, 由 ASN-GW记录用户终端标识( MS ID, Mobile Station Identifier )、 月良务流标识( SF ID, Service Flow Identifier )、 数据 通道标识(DP ID, Data Path Identifier )及其对应关系; BS记录初始业务通道 空口连接标识( CID , Connection Identifier )、 SF ID、 DP ID及其对应关系; 用 户终端记录初始业务通道的 CID、 SF ID和相关上下文信息。
接着进入步骤 330, 在建立的初始业务通道上, 通过 3层信令的交互进行 该用户终端 IP地址的分配。 为该用户终端分配的 IP地址可以是移动 IP用户 终端的家乡地址(Home Address, 简称' ΉοΑ" )或转交地址( Care-of Address, 简称" CoA" ), 或简单 IP ( Simple IP )用户终端的 IP地址。 在该初始业务通道 上进行交互的 3 层信令包括: 动态主机配置协议第四版 (Dynamic Host Configuration Protocol version 4 , 简称" DHCPv4" )的协议消息、 动态主机配置 协议第六版 ( Dynamic Host Configuration Protocol version 6 , 简称" DHCPv6,, ) 的协议消息、 移动网间互联协议第 4版( Mobile Internet Protocol version 4 , 简 称" MIPv4,, ) 的协议消息、 移动网间互联协议第 6版( Mobile Internet Protocol version 6, 简称" MIPv6" ) 的协议消息、 邻区发现协议消息等。
用户终端成功分配 IP地址后, 进入步骤 340, ASN-GW中相关功能实体 发起预置流业务建立过程, 在该过程中, ASN-GW根据所分配的用户终端 IP 地址, 建立网络侧的下行预置流分类器和 /或用户终端侧的上行预置流分类器 并对所建立的预置流分类器的参数进行设置。由于上行和下行的预置流分类器 的建立是在用户终端成功分配 IP地址之后进行的, 从而能够确保在建立上行 和 /或下行预置流分类器的过程中, 分类器的 IP地址参数得到正确设置, 使得 所建立的预置流分类器能够正常分类该用户终端的预置流业务,避免了现有技 术中因用户终端 IP地址缺失而导致的所建立的预置流分类器无法正常工作的 现象。
本发明第二实施方式预置流分类器的建立方法与第一实施方式大致相同, 其区别仅在于在第一实施方式中,在用户终端成功分配 IP地址后,由 ASN-GW 中相关功能实体发起预置流业务建立过程, 在该过程中, ASN-GW根据该成 功分配的 IP地址, 建立用户终端侧和 /或网络侧的预置流分类器; 而在本实施 方式中, 在用户终端成功分配 IP地址后, ASN-GW所发起的预置流业务建立 过程中, 由 BS才艮据该成功分配的 IP地址, 建立用户终端侧和 /或网络侧的预 置流分类器。 也就是说, 在本实施方式中, 由 BS 建立下行预置流分类器和 / 或上行预置流分类器。
下面对本发明第三实施方式预置流分类器的建立系统进行说明。
本实施方式中预置流分类器的建立系统与第一实施方式大致相同,包括地 址分配设备和分类器建立设备。 其区别仅在于本实施方式中, 分类器建立设备 还用于在用户终端入网成功后, 直接为其建立预置流分类器, 并在地址分配设 备为该用户终端成功分配 IP地址后, 根据所分配的 IP地址设置(即修改) 已 建立的预置流分类器的参数。
本发明第四实施方式的预置流分类器的建立系统与第一实施方式大致相 同, 包括地址分配设备、 分类器建立设备(第二分类器建立设备)、 和预置流 参数修改设备。其区别仅在于本实施方式中, 分类器建立设备用于在用户终端 入网成功后, 直接建立预置流分类器, 地址分配设备在已建立的预置流上, 通 过信令交互为用户终端分配 IP地址; 在地址分配设备为该用户终端成功分配 IP地址后, 由预置流参数修改设备根据所分配的 IP地址设置 (即修改) 已建 立的预置流分类器中的用户终端的 IP地址参数。 上述第三和第四实施方式的所述系统还可以包括用户终端,用于在所述地 址分配设备为所述用户终端成功分配 IP地址后, 以该 IP地址设置 (即修改) 用户终端侧预置流分类器(即上行预置流分类器) 的参数。
在实际应用中,上述系统中网络侧的地址分配设备可以是 ASN-GW、 HA、 DHCP服务器、 AAA服务器中的一个或多个,分类器建立设备可以是 ASN-GW 或 BS。
以上对本实施方式的系统进行了说明,下面对本实施方式预置流分类器的 建立方法进行介绍。
具体如图 4所示, 在步骤 410中, 用户终端发起初始入网过程, 在用户终 端成功入网后, 进入步骤 420。
在步骤 420中, ASN-GW直接发起预置流业务建立过程,在该过程中, BS 建立上行和 /或下行的预置流分类器, 所建立的上行和 /或下行预置流分类器的 IP地址参数为空。
接着进入步骤 430, HA或 DHCP服务器通过已建立的预置流承载 3层信 令, 为用户终端分配所需的 IP地址。 在 IP地址分配成功后, 由 ASN-GW记 录该用户终端所分配的 IP地址。
接着进入步骤 440, ASN-GW根据所记录的用户终端的 IP地址, 发起预 置流修改过程, 通知 BS和 /或用户终端为已建立的预置流分类器修改 IP地址 参数。 用户终端和 /或 BS收到通知后, 才艮据所分配的 IP地址对上行预置流分 类器和 /或下行预置流分类器中 IP地址参数进行修改, 确保所建立的上行和下 行预置流分类器中 IP地址参数的正确性, 使得所建立的预置流分类器能够正 常分类用户终端的预置流业务。由于本实施方式沿用了现有技术先建立预置流 分类器后分配 IP地址的流程, 使本发明实施例对现有技术的改动最小化, 提 高了本发明实施例对现有技术的兼容能力。
本发明第五实施方式的预置流分类器的建立方法与第四实施方式大致相 同, 其区别仅在于, 在第四实施方式中, 在用户终端 IP地址成功分配后, 由 ASN-GW根据该 IP地址发起预置流修改过程, 通知 BS和 /或用户终端修改已 建立的预置流分类器中的 IP地址参数; 而在本实施方式中, 在用户终端 IP地 址成功分配后, 由 BS根据下行 IP报文自行获取所分配的 IP地址, 根据该 IP 地址修改下行预置流分类器的 IP地址参数; 和 /或, 通过空口消息通知用户终 端根据该 IP地址修改上行预置流分类器的 IP地址参数。
本发明第六实施方式预置流分类器的建立方法与第四实施方式大致相同, 其区别仅在于, 在第四实施方式中, 在用户终端 IP 地址成功分配后, 由 ASN-GW根据该 IP地址发起预置流修改过程, 通知 BS和 /或用户终端修改已 建立的预置流分类器中的 IP地址参数; 而在本实施方式中, 在用户终端 IP地 址成功分配后, 由用户终端和 /或 BS 自行获取所分配的 IP地址, 并主动根据 该 IP地址分别修改上行和 /或下行预置流分类器的 IP地址参数。
本发明第七实施方式预置流分类器的建立方法与第四实施方式大致相同, 其区别仅在于在第四实施方式中,在 ASN-GW发起的预置流业务建立过程中, 由 BS建立上行和 /或下行预置流分类器; 而在本实施方式中, 在 ASN-GW发 起的预置流业务建立过程中, 由 ASN-GW建立上行和 /或下行预置流分类器。 在 IP地址分配成功后, ASN-GW直接根据该 IP地址修改下行预置流分类器的 IP地址参数,和 /或通知用户终端对上行预置流分类器的 IP地址参数进行修改; 或者, 在 IP地址分配成功后, 用户终端和 /或 ASN-GW通过内部原语自行修 改上行和 /或下行预置流分类器的 IP地址参数。
本发明的第八实施方式是一种用户终端, 至少包含以下单元:
在入网成功后与网络侧建立用于承载 3层信令的初始业务通道的单元;通 过初始业务通道与网络侧进行 3层信令的交互,获得网络侧为本用户终端分配 的 IP地址的单元; 在 IP地址分配成功后以该 IP地址设置预置流分类器的参 数的单元。
本发明实施例的用户终端可以保证建立的预置流分类器中用户终端 IP地 址的正确性, 使建立的预置流分类器能够正常分类该用户终端的预置流业务。
虽然通过参照本发明的某些优选实施方式,已经对本发明进行了图示和描 述,但本领域的普通技术人员应该明白, 可以在形式上和细节上对其作各种改 变, 而不偏离本发明的精神和范围。
