Description

一种标识网与传统网络互联互通的方法、 ASR及 ISR
技术领域
本发明涉及通信技术领域, 尤其涉及一种标识网与传统网络互联互通的 方法、 ASR及 ISR。 背景技术
现有因特网广泛使用的 TCP/IP ( Transmission Control Protocol/Internet Protocol, 传输控制协议 /互联网络协议)协议中的 IP地址具有双重功能, 既 能作为网络层的通信终端主机的网络接口在网络拓朴中的位置标识, 又能作 为传输层主机的网络接口的身份标识。但 TCP/IP协议在设计之初并未考虑主 机移动的情况。 因此, 当主机移动越来越普遍时, 这种 IP地址的语义过载缺 陷日益明显。 当主机的 IP地址发生变化时, 不仅路由会发生变化, 通信终端 主机的身份标识也会发生变化, 这将导致路由负载越来越重, 而且主机标识 的变化还将导致应用和连接的中断。
身份标识和位置分离问题的提出,是为了解决 IP地址的语义过载和路由 负载严重等问题,将 IP地址的双重功能进行分离, 实现对移动性、多家乡性、 IP地址动态重分配、 减轻路由负载及下一代互联网中不同网络区域之间的互 访等问题的支持。
现有技术中, 基于网络路由器的实现方法是对身份标识和位置进行分离 的解决方案之一。
申请号为 200910174691.6的中国发明申请公开了一种基于网络的身份标 识和位置分离方法, 以下对该方法所应用到的网络简称为标识网, 该方案的 基本思想是: 将标识网划分为接入层和核心层, 网络中的移动节点有两种标 识类型: 用户身份标识 (Access Identifier, 简称为 AID ) 和路由位置标识 ( Routing-Location Identifier, 简称为 RID ) ; 为网络中的每个用户配置唯一 的 AID, 该 AID在移动过程中始终保持不变; 在数据转发过程中, AID只能 在接入层使用, RID只能在核心层使用; 在用户终端间进行应用层通信时, 使用 AID识别对端。
上述基于网络的身份标识和位置分离框架的标识网拓朴示意图如图 1所 示, 主要包括: 接入业务路由器 ( Access Service Router, 简称为 ASR ) 、 身 份位置寄存器(Identifier Locator Register, 简称为 ILR ) 、 互通业务路由器 ( Interworking Service Router, 简称为 ISR )等。 移动节点、 固定节点及游牧 节点通过接入网接入到标识网中。下面对标识网中的相关网元分别给予介绍:
ASR负责为各种移动节点提供接入服务, 为接入的用户分配 RID, 并将 用户的数据报文进行标识封装后在骨干网中进行传输。
ASR在收到终端发来的数据报文时, 根据数据报文中目的地址(即通信 对端的 AID )查询本地緩存 ( CACHE )中的 AID-RID映射表: 如果查找到对 应的 AID-RID映射条目,则将查到的通信终端的 RID封装在报文头部发送到 骨干网进行转发处理; 如果没有查到对应的 AID-RID映射条目, 则将数据报 文转发到骨干网, 并向 ILR发起查询通信对端的 AID-RID映射信息的流程, 将 ILR返回的相应的 AID-RID映射条目保存在本地, 以备后续报文转发时查 询。
或者, ASR在本地没有查找到对应的 AID-RID映射条目时, 也可以选择 不将数据报文转发到骨干网, 而是直接向 ILR 发起查询该通信对端的 AID-RID映射信息的流程 , 待 ILR返回相应的 AID-RID映射条目后 , 将查到 的该通信终端的 RID封装在报文头部发送到骨干网进行转发处理。
ASR在收到发往终端的数据报文时, 对该数据报文进行解封装处理, 剥 去该数据报文中新增的包含 RID的报文头后, 发往终端。
ILR 主要负责维护网络中用户身份标识和位置标识的映射关系, 并向 ASR和其它映射服务器提供查询服务。
在相关技术中, 标识网的终端访问传统网络的终端需要通过 ISR进行互 访。
ISR作为标识网与传统网络的互通网关路由器, 负责向传统网络发布标 识网 AID的路由信息; 当传统网络终端访问标识网的 ^艮文通过 ISR进入标识 网时, ISR根据目的地址( AID )查询 AID-RID映射关系, 然后进行外层 RID 封装。
标识网内终端访问传统网络的 文通过 ISR出口, 具体流程为: ASR在 收到终端发来的报文后, 判断该报文的目的地址是否是标识网 AID范围内的 地址, 如果不是标识网 AID范围内的地址, 则用 ISR的 RID进行外层封装后 发往 ISR, ISR在收到后去掉 "^文的外层 RID封装后发往传统网络。
但是在实际组网部署时, 标识网通常会同时与多个传统网络互通, 如图 2所示, 也就是说, 一个标识网会存在多个 ISR (如 ISR1和 ISR2 ) 。 因此, ASR在收到终端 (UE )发来的报文后, 当判断出目的地址不是标识网 AID 范围内的地址时, 无法判断出应该把该报文发送给哪一个 ISR。
发明内容
本发明针对上述问题,提供一种标识网与传统网络互联互通的方法、 ASR 统网络的 ^艮文发送给哪一个 ISR的问题。

图 1为相关技术的基于网络的身份标识和位置分离架构的网络拓朴示意 图;
图 2为相关技术的基于网络的身份标识和位置分离框架的网络与多个传 统网络互通的示意图;
图 3为本发明实施例中 ISR与 ILR交互流程示意图。 本发明的较佳实施方式
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。
本实施例主要基于身份标识和位置分离的网络架构和协议, 提出一种标 识网与传统网络互联互通的方法。 需要说明的是, 在本文中, 目的地址即指 目的 AID, 相应地, 目的 AID即指目的地址。
ASR侧的具体处理流程如图 3所示, 包括:
( 301 ) ASR接收到 UE发来的报文;
( 302 ) ASR根据该报文携带的目的 AID判断该目的 AID是否属于标识 网 AID范围内的地址; 如果判断出该目的 AID属于标识网 AID范围内的地 址, 执行步骤 303a; 否则, 执行步骤 304;
( 303a ) ASR根据本地緩存的 AID和 RID映射条目查找该目的 AID对 应的 RID; 如果在本地没有查找到该目的 AID对应的 RID, 则向 ILR查询获 取相应的 AID和 RID映射条目;如果本地保存有该目的 AID对应的 RID,则 执行步骤 303b;
( 303c ) ASR查找路由表后对封装好的报文进行转发, 结束;
( 304 )说明该报文是发往传统网络的报文, 因此 ASR直接查路由表进 行报文转发, 不需要做外层封装。 其中, 该路由表可以是由 ASR根据路由协 议获取到的路由信息生成的, 也可以是由网管通过手工配置到 ASR上的; 相应地, ISR在收到 ASR发来的报文后, 根据路由表将该报文转发到传 统网络。
综上所述, 从上述实施例可以看出, ASR和 ISR的功能与现有技术相比 有所不同:
对于 ASR来说, 在现有技术中, 对于上行报文, ASR会根据目的 AID 进行判断, 如果目的 AID属于传统网络, 则用 ISR的 RID进行封装后, 发送 给 ISR; 在上述实施例中, 对于上行报文, ASR判断其目的 AID如果不是标 识网 AID范围内的地址,则不进行外层封装,直接根据路由表进行报文转发, 报文会按照路由方式被转发到正确的 ISR, 由 ISR转发到传统网络。
对于 ISR来说, 在现有技术中, 对于发往传统网络的报文, 由于存在外 层 RID封装,因此 ISR需要解除报文外层的 RID封装后,再发送到传统网络; 因此, ISR也就不再需要解除外层封装, 而是直接按路由方式将报文转发给 传统网络即可。
更进一步的, ISR可以获取传统网络路由信息, 并将传统网络路由信息 向标识网内发布, 以保证标识网发往传统网络的报文在标识网内能够被路由 到正确的 ISR。 其中, 传统网络路由信息可以是由 ISR根据路由协议获取到 的, 也可以是由网管通过手工配置到 ISR上的。
在本实施例中, 一种标识网, 包括: 接入业务路由器和 2个以上的互通 业务路由器:
所述接入业务路由器用于在接收到用户设备发来的报文后, 若判断出所 述报文的目的地址不属于本标识网的用户身份标识范围内, 则根据第一路由 表对所述报文进行转发;
所述互通业务路由器用于在接收到所述接入业务路由器发来的所述报文 后, 根据第二路由表将所述报文转发到传统网络。
较佳地, 所述第一路由表是由所述接入业务路由器根据路由协议获取到 的路由信息生成的, 或是预配置在所述接入业务路由器上的。
较佳地, 所述第二路由表是由所述互通业务路由器根据路由协议获取到 的路由信息生成的, 或是预配置在所述互通业务路由器上的。
相应地, 本实施例还提供了一种接入业务路由器, 包括:

判断模块, 用于判断所述报文接收模块接收到的所述报文的目的用户身 份标识是否属于本标识网的用户身份标识范围内;

较佳地, 所述接入业务路由器还可包括:
路由获取模块, 用于利用根据路由协议获取到的路由信息生成所述路由 表。 较佳地, 所述接入业务路由器还可包括:
存储模块, 用于保存预配置的所述路由表。
