Description

一种数据传输的方法及网关 技术领域
本发明涉及通信领域,尤其涉及到一种数据传输的方法及网关。
背景技术
移动运营商在建立大规模的通用分组无线业务( General Packet Radio Service , GPRS ) / 演进分组核心网络( Evoloved Packet Core , EPC ) 时,为便于管理,采用分层组网,比如中国联通和中国移动的 GPRS/EPC 网络,都是以省为单位进行组建,省 GPRS/EPC 网络 负责向该省所在的用户提供 GPRS/EPC 服务,即同一个 公共陆地移动网络( Public Land Mobile Network , PLMN ) 可以划分成多个签约归属地的 GPRS/EPC 网络,一般业务有以下三种情况,即在某 PLMN 的签约归属地的业务;漫游至非签约归属地但仍属于 该 PLMN 的业务;漫游至其他 PLMN 的业务。
在漫游至非归属 PLMN 的业务的应用场景中,用户设备发起的业务请求经过漫游地网络设备接入漫游地网络并发送关口局的网关,最后经由 关口局的网关 发往外部分组数据网( Packet Data Network , PDN ),漫游地网络设备可以为业务 GPRS 支持节点( Serving GPRS Support Node , SGSN ) / 业务网关( Serving Gateway , S-GW ) ,关口局的网关可以为网关 GPRS 支持节点( Gateway GPRS Support Node , GGSN ) /PDN 网关( PDN Gateway , P-GW ) 。
用户设备发起接入请求的时候,要指定一个接入点名称( Accesss Point Name , APN ) 作为接入点名, APN 用于标识一个指定的外部网络和一种服务的 Internet 服务提供商( Internet Server Provider , ISP ) ,在 漫游地网络设备 中可根据 APN 并 通过 DNS 域名解析得到与此 APN 对应的关口局的网关地址。
一般 APN 分成两种:支持全网接入的通用 APN 和支持区域接入的区域 APN 。其中,通用 APN 用于通过全国的 GPRS/EPC 网络将用户发起的业务请求接入 Internet ,区域 APN 用于通过特定省 GPRS/EPC 网络将用户发起的业务请求接入 Internet 。
对漫游至非归属 PLMN 网络的用户,如果使用通用 APN ,目前的处理都是直接在关口局的 网关 上直接激活进行处理,不能回到该用户所述的签约归属地的 GGSN/PGW , 而 在手机上设置带有地名后缀的 APN ,取消通用 APN 的配置,虽然可以实现用户漫游时回归属地 GGSN/PGW 的问题,但是,由一个通用 APN 衍生为多个区域 APN ,会增加了 APN 的管理;对用户设备而言,仅看到的是本地签约网的区域 APN ,不利于移动运营商集团公司建立统一的业务发展策略。
