技术领域 本发明涉及通信领域, 尤其涉及一种获取终端身份标识的方法、 装置及 终端。
背景技术
在现有的通信网络中, 当终端获取到了 IP ( Internet Protocol , 网际协议) 地址后, IP地址就成了该终端在路由层面上的位置标识, 也是身份标识。 用 户发送或者接收数据包时,是通过网络侧已分配的 IP地址来实现发送或者接 收数据包。 如果终端发生移动 (跨分配地址的网元的移动) , 就会出现更换
IP地址的问题, 于是在 LTE ( Long Term Evolution, 长期演进)或者 eHRPD ( evolved High Rate Packet Data, 演进的高速率分组数据 ) 网络中引入了移 动 IP的方案, 但是移动 IP方案并没有彻底解决由于终端发生移动而导致更 换 IP地址的问题。 针对以上问题, 将位置和身份分离的思想运用到 LTE网络或者 eHRPD 网络或者其他的分组域网络中, 将是一个行之有效的解决方案。 在现有 LTE网络中, 用户是通过 IMSI ( International Mobile Subscriber Identity, 国际移动用户标识 )标识用户的唯一身份, 在 3GPP2的 eHRPD网 络中是通过 NAI ( Network Access Identifier, 网络接入标识)来标识用户的 唯一身份, 在其他分组域网络中, 也有其他不同的唯一标识来标识该用户的 身份。 如果直接利用现有网络中的该些传统用户身份标识(IMSI或者 NAI 等)实现身份位置分离, 会对终端造成很大的改动, 影响终端的协议栈结构, 而且不能兼容传统的终端。

本发明的较佳实施方式 下面将结合附图及实施例对本发明的技术方案进行更详细的说明。 具有位置和身份分离的网络架构的通信系统中有两种标识类型: 接入标 识(AID: Access Identifier )和路由标识(RID: Routing Identifier ) 。 其中, AID是终端的用户身份标识, 网络为每个终端用户唯一分配一个 AID , 在终 端移动过程中始终保持不变; RID是网络为终端分配的位置标识, 在骨干网 使用。 身份标识和位置标识在不同的网络架构可以有不同的名称。 图 1 ( a )示出了位置和身份分离的网络架构的部分拓朴, 包括接入网、 接入节点(图中接入节点为 ASN ( Access Service Node, 接入服务节点 ) ) 、 分组数据网络、 认证中心和身份位置寄存器。 如图 1 ( b )和图 1 ( c )所示, 在位置和身份分离的网络架构下, 网络划 分为接入网和骨干网, 接入网位于骨干网的边缘, 负责本网络终端的接入。 骨干网负责通过接入网接入的终端的数据报文的路由和转发。 ASN位于骨干 网和接入网的分界点, 与接入网、 骨干网接口。 接入网与骨干网在拓朴关系 上没有重叠。 其中, 在基于身份标识和位置分离架构网络中, 为每个用户终端唯一分 配一个 AID, AID在接入网使用, 在终端的移动过程中始终保持不变; RID 是为终端分配的位置标识, 在骨干网使用。 骨干网分为映射转发平面和广义转发平面, 广义转发平面主要用于根据 数据报文中的 RID进行选路和转发以 RID为目的地址的数据报文,广义转发 平面内的数据路由转发行为与传统 IP网络(Legacy IP网络)一致。 广义转 发平面的主要网元包括 CR( Common Router,通用路由器)和 ISN( Interconnect Service Node, 互联服务节点)。 映射转发平面主要用于保存终端的身份位置 映射信息 (即 AID-RID的映射信息) , 处理对终端位置的登记注册和查询, 路由并转发以 AID 为目的地址的数据报文。 映射转发平面的主要网元包括 ILR/PTF ( Identity Location Register/Packet Transfer Function, 身份位置哥存器 /分组转发功能) 。 在图 1 ( b ) 中, ASN在架构的划分中独立于骨干网。 在图 1 ( c ) 中, 骨干网包括 ASN。 图 1 ( b )和图 1 ( c )只是架构划分的不同, ASN实际完 成的功能是一样的。 参见图 1 ( a ) 〜 ( c ) , 其中: 接入网为用户终端提供二层(物理层和链路层)接入服务, 可以是蜂窝 移动网、 DSL ( Digital Subscriber Line , 数字用户线) 、 宽带光纤接入网或 WiFi ( WirelessFidelity, 无线相容性认证)接入网等。 分组数据网络可以是 IP网络。 终端: 基于网络的身份标识和位置分离架构中, 接入的用户终端可以是 移动节点、 固定节点及游牧节点中的一种或多种。 接入节点: 是连接无线接入网和分组数据网络的边界节点, 负责终端到 分组数据网络的接入, 为了实现终端的身份标识和位置分离, 接入节点还为 终端分配 RID, 维护终端的 AID-RID映射信息, 到 ILR ( Identity Location Register, 身份位置寄存器)登记注册和查询终端的 RID, 实现无线接入网与 分组数据网络之间, 接入节点之间的数据报文的路由和转发, 以及与其他接 入节点配合实现终端切换等。 接入节点还负责代理 IPV4/IPV6终端实现基于 网络的身份标识和位置分离架构 AID数据报文与 IPV4/IPV6数据报文的兼容 性处理。 在本发明实施例中, 接入节点为 ASN。
CR ( Common Router, 通用路由器): 路由并转发以 RID格式为源地址
/目的地址的数据报文。该通用路由器的功能作用与现有技术中的路由器没有 区别。 认证中心: 负责记录身份标识和位置分离架构网络中的用户属性, 包括 用户类别、 鉴权信息和用户服务等级等信息, 产生用于鉴权、 完整性保护和 加密的用户安全信息, 在用户接入时对用户进行合法性认证和授权。 认证中 心支持身份标识和位置分离架构网络与用户间的双向鉴权。
ILR/PTF ( Identity Location Register/Packet Transfer Function, 身份位置哥 存器 /分组转发功能): ILR和 PTF可以为同一实体上的两个功能模块, 位于 骨干网的映射转发平面中。 ILR维护 /保存基于网络的身份标识和位置分离架 构中用户的 AID-RID映射关系, 实现登记注册功能, 处理通信对端的位置查 询流程; PTF在收到 ASN送达的数据报文后, 由 PTF根据目的 AID路由并 转发。 映射转发平面内 PTF节点在查到目的 AID-RID的映射关系后, 在数 据报文头部封装 RID信息并转发到广义转发平面内路由到通信对端。 ISN ( Interconnect Service Node, 互联服务节点): 用于查询、 维护本架 构网络终端的 AID-RID映射信息, 封装、 路由和转发本架构网络与传统 IP ( Legacy IP ) 网络之间往来的数据报文, 实现本架构网络与 Legacy IP网络 间的互联互通功能。 在本架构移动终端发生切换时, ISN作为该移动终端在 本架构网络与 Legacy IP间的代理锚点。 在不同的位置和身份分离的网络架构中,上述节点可能具有不同的名称, 如接入节点也可以叫作接入路由器、 接入服务器, 在 LISP ( Locator/ID Separation Protocol ,位置身份分离协议 )架构中则相当于隧道入口路由器和 隧道出口路由器的合体。 而身份位置寄存器也可以叫作映射服务器, 等等。
为了能够在对传统终端改动最小或者不影响传统终端的前提下, 在分组 域网络中实现终端位置和身份标识的分离,本发明提出一种终端获取 AID的 方法, 应用于具有身份标识和位置分离的网络架构的通信系统, 参见图 2, 包括步骤: 步骤 201 : 在所述通信系统中配置终端的传统用户身份标识与接入标识 (AID)的对应关系信息, 所述 AID是所述通信系统为终端用户分配的唯一标 识, 也可称为身份标识; 在现有的通信网络中, 终端用户釆用传统身份标识来标识所述终端用户 的唯一身份, 在不同的分组网络中终端的传统用户身份标识不同, 例如, 在 现有 LTE 网络中, 终端的传统用户身份标识是 IMSI ( International Mobile Subscriber Identity, 国际移动用户标识), 在 eHRPD网络中终端的传统用户 身份标识是 NAI ( Network Access Identifier, 网络接入标识) , 在其他分组 域网络中, 终端的传统用户身份标识为其他用以标识终端用户的唯一身份的 标识。 步骤 202: 所述终端接入所述通信系统时, 在向所述通信系统发送的信 令中携带所述终端的传统用户身份标识; 步骤 203 : 所述通信系统从所述信令中获取所述终端的传统用户身份标 识, 从所述对应关系信息中查找到所述传统用户身份标识对应的 AID, 并将 该 AID返回给所述终端。
