Description

一种实现业务服务器地址解析的方法、 终端及系统
本申请要求于 2008 年 7 月 17 日提交中国专利局、 申请号为 200810133568.5、 发明名称为 "一种实现业务平台地址解析的方法及终端" 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
本发明涉及通信技术领域, 特别涉及一种实现业务服务器地址解析的方 法、 终端及系统。
背景技术
随着通信技术的发展,因特网在人们的日常工作生活中有着越来越重要的 地位。 因特网中的主机可以有多种方式标识, 例如统一资源定位符( Uniform Resource Locator, URL ) i或名和网际十办议 ( Internet Protocol, IP )地址, URL 域名几乎不包括主机在因特网中的位置信息,例如 cnn.com 或者 www.yahoo.com , 而 IP 地址对应主机在因特网中的位置信息, 例如 192.158.100.011 ; 但是, 由于 URL域名具有助记性, 而 IP地址是数字型名字, 难于理解和记忆, 因此, 人们一般通过 URL域名访问对应的主机。
通过 URL域名访问对应的主机, 需要先通过因特网的域名服务( Domain Name Service, DNS )服务器根据 URL域名查询到与该 URL域名对应的 IP 地址, 再由浏览器根据对应的 IP地址访问对应的业务服务器。
目前基于无线应用协议 ( Wireless Application Protocol, WAP ) 浏览的业 务, 可以采用 WAP网关代理方式访问业务服务器, 即: WAP网关代理客户端 向 DNS服务器发起 DNS解析流程,在这种访问方式下,客户端中统一预置现 有 WAP网关的 IP地址; 或者, 也可以不采用 WAP网关代理方式访问业务月^ 务器, 即: 客户端可以直接访问 DNS服务器, 由 DNS服务器解析业务服务器 的地址后返回给客户端。
在实现本发明的过程中, 发明人发现: 对于采用 WAP网关代理方式访问 业务服务器的业务,如果 WAP网关地址变化,则客户端不能正常接入该业务; 对于不采用 WAP网关代理方式访问业务服务器的业务, DNS服务器根据域名 解析到的业务服务器地址是拜访地业务服务器地址,因此,客户端将根据 DNS 解析出的拜访地业务服务器的地址直接接入拜访地业务服务器,而无法选择归 属地业务服务器进行服务。
发明内容
本发明实施例提供一种实现业务服务器地址解析的方法、终端及系统,使 得终端可以根据业务需要, 接入归属地业务服务器。
本发明实施例提供了一种实现业务服务器地址解析的方法, 该方法包括: 获取归属信息;
将所述归属信息加入 DNS请求中, 得到归属 DNS请求, 所述 DNS请求 携带 URL域名;
将所述归属 DNS请求发送给 DNS服务器;
从所述 DNS服务器接收所述归属 DNS请求对应的归属地业务服务器的 IP 地址。
本发明实施例还提供了一种终端, 该终端包括:
归属信息获取模块, 用于获取自身所属终端的归属信息;
DNS 请求模块, 用于根据业务需求, 将所述归属信息获取模块获取的归 属信息加入 DNS请求中,得到归属 DNS请求,所述 DNS请求携带 URL域名; 信息交互模块, 用于将所述 DNS请求模块得到的归属 DNS请求发送给 DNS服务器; 并从所述 DNS服务器接收所述归属 DNS请求对应的归属地业 务服务器的 IP地址。
本发明实施例还提供一种实现业务月良务器地址解析的系统, 该系统包括: 终端, 用于获取归属信息, 将所述归属信息加入域名服务 DNS请求中, 得到归属 DNS请求, 所述 DNS请求携带统一资源定位符 URL域名; 将所述 归属 DNS请求发送给 DNS服务器;从所述 DNS服务器接收所述归属 DNS请 求对应的归属地业务月良务器的网际协议 IP地址;
DNS服务器, 用于接收所述终端的归属 DNS请求, 查询得到归属 DNS 请求对应的归属地业务服务器的 IP地址, 并将该 IP地址返回给终端。
采用本发明实施例的技术方案, 可以由终端根据归属信息发起归属 DNS 请求,并根据 DNS服务器返回的归属 DNS请求对应的归属地业务服务器的 IP 地址访问归属地业务服务器,从而使得终端可以根据业务需要,接入归属地业 务服务器。 附图说明
图 1 所示为本发明实施例一中实现业务服务器地址解析的方法流程示意 图;
图 2所示为本发明实施例二中实现业务服务器地址解析的方法流程示意 图;
图 3所示为本发明实施例三中终端结构示意图。
具体实施方式
对于不采用 WAP网关代理方式访问业务服务器的业务,当 DNS服务器根 据域名解析到归属地业务服务器地址和拜访地业务服务器地址,根据现有协议 的规定,客户端直接接入拜访地业务服务器, 而无法选择归属地业务服务器进 行服务。 其中, 不采用 WAP网关代理方式访问业务服务器的业务可以包括但 不限于无线一键通 ( Push to talk over Cellular, POC ) 业务、 视频共享 (Video Sharing )业务或者辅助全球卫星定位系统( Assistant-Global Positioning System, AGPS )等。
为了使客户端(即下文所述终端 )能够根据业务需要, 接入归属地业务服 务器, 终端可以使用本发明实施例提供的方法实现业务。
实施例一,一种实现业务服务器地址解析的方法,参见图 1 ,该方法包括: 步骤 101、 终端获得归属信息。
终端可以从自身的用户识别号中获得归属信息。其中, 用户识别号可以包 括但不限于国际移动用户识别码 ( International Mobile Subscriber Identity , IMSI ) 或者移动用户综合服务数字网号码 (MS Integrated Services Digital Network, MSISDN ); 归属信息可以包括但不限于终端归属地的区号, 例如, 终端的归属地为北京, 归属信息可以为北京的区号 "010" , 或者, 终端的归属 地为深圳, 归属信息可以为深圳的区号 "0755" , 等等。
步骤 102、 根据业务需求, 终端将归属信息加入 DNS请求中, 得到归属
DNS请求, DNS请求携带 URL域名。
具体的, 可以由终端将归属信息以给定的格式加入 DNS请求携带的 URL 域名中, 得到归属 URL域名。
给定的格式可以包括但不限于: 终端将归属信息作为 URL域名对应空间 的叶子节点的信息,加入 URL域名中。 URL域名对应空间通常称作域名空间, 域名空间是一个呈树状、 层次结构的分布式数据库, 主机则位于树的叶子上。 完整的 URL 域名由该树的一个节点到根节点路径上节点标识的有序序列组 成,其中,各节点标识符之间用". "隔开。例如, URL域名为 home.weather.com, 将归属信息作为 URL域名对应空间的叶子节点的信息,加入 URL域名, 以归 属信息为 010为例, 则归属 URL域名为 010.home.weather.com o
步骤 103、 终端将归属 DNS请求发送给 DNS服务器。
该 DNS服务器的地址可以在终端激活时从网络侧获得, 或者在终端上预 先进行配置。
步骤 104、 终端从 DNS服务器接收归属 DNS请求对应的归属地业务服务 器的 IP地址。
DNS服务器根据含有归属信息的归属 URL域名, 按照现有的域名解析方 法查询出归属 DNS请求对应的归属地业务服务器的 IP地址, 并将该 IP地址 返回给终端。 终端可以根据获得的 IP地址, 访问归属地业务服务器。
采用本实施例的技术方案,可以由终端根据归属信息发起归属 DNS请求, 并根据 DNS服务器返回的归属 DNS请求对应的归属地业务服务器的 IP地址 访问归属地业务服务器,从而使得终端可以根据业务需要,接入归属地业务服 务器。
实施例二,本实施例是将实施例一的方法在实际组网中的应用,参见图 2, 图 2中, 通用无线分组业务网关支持节点 ( Gateway GPRS Supporting Node,
GGSN ) 作为无线网络的接入装置; 通用路由封装 ( Generic Routing
Eiicapsiilatioii , GRE )路由器作为核心网络的接入装置; WAP网关(GW )在 组网中作为网关, 但不代理访问业务服务器 SP。
本实施例的具体应用场景为终端 MS的业务要求访问归属地业务服务器, 例如, 北京用户漫游到上海, 仍希望查看北京的天气预报。 实现业务服务器地 址解析的方法, 参见图 2, 该方法包括:
步骤 201、 MS进行分组数据协议( Packet Data Protocol, PDP )激活。 步骤 202、 GGSN在激活响应中推送 DNS服务器的地址给终端。
步骤 201和步骤 202也可以没有, MS使用预置的 DNS服务器的地址。 步骤 203、 MS进行业务时,经由 GRE路由器向 DNS服务器发送归属 DNS 请求; 其中, MS可按业务要求, 在 DNS请求的 URL域名前扩展归属信息, 组合成归属 DNS请求。
MS将获得的归属信息(例如,可以从 IMSI中获得或从 MSISDN中获得) 进行处理, 以给定的格式加入 DNS请求的 URL域名中,生成含有归属信息的 URL, 归属 DNS请求中携带的归属 URL可以是: 归属信息 +URL域名,例如: 所要进行的业务是"用户归属地天气预报", MS获得的归属信息是 " 010" , 归 属地天气预报业务 URL域名是 "home.weather.com" , 将归属信息加入到 DNS 请求的 URL域名中可以为 "010. home.weather.com"。
步骤 204、 DNS服务器返回 SP的地址给终端。
务器, 根据收到的含有终端归属信息的 URL域名, 查询出终端归 属地 SP的 IP地址。
步骤 205、 MS根据 DNS返回的归属地 SP的 IP地址, 与归属地 SP之间 建立连接。
采用本实施例的技术方案, 由 MS根据归属信息发起归属 DNS请求, 并 根据 DNS服务返回的归属 DNS请求对应的归属地业务服务器的 IP地址访问 归属地业务服务器,从而使得终端可以根据业务需要,接入归属地业务服务器, 查看到北京的天气预报。
实施例三,本实施例是实施例一和实施例二中实现业务良务器地址解析的 方法的执行主体, 即一种终端, 参见图 3, 该终端可以包括:
归属信息获取模块 301 , 用于获取终端的归属信息。
