Description

切换承载的方法、 家庭基站网关和家庭基站 本申请要求于 2011 年 10 月 31 日提交中国专利局、 申请号为 201110337665.8、 发明名称为"切换承载的方法、 家庭基站网关和家庭基站" 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
本发明涉及通信领域, 特别涉及通信领域中切换承载的方法、 家庭基 站网关和家庭基站。 背景技术
家庭基站(Home NodeB, 简称为 "HNB" )可以用于扩展移动网络的覆 盖范围, 以及提供更多具有针对性的服务。 HNB可以不属于家庭或企业, 并且可以通过宽带连接与移动运营商的网络连接。具有访问 HNB权限的终 端可以通过第三代移动通信技术(3rd-Generation, 简称为 "3G" )或长期演 进( Long Term Evolution , 简称为 "LTE" )系统的 HNB接入移动运营商的网 络来获取服务。
利用 HNB还可以在企业或家庭部署本地网络, 从而接入 HNB的用户 设备( User Equipment,简称为" UE" )能够访问家庭基站所部署的本地网络, 而用户数据无需流经运营商核心网。
在目前的 HNB系统构架中,本地网关( Local Gate Way,简称为" LGW" ) 和 HNB集成在一起, LGW和 HNB的地址相同。支持本地 IP(互联网协议 ) 访问 ( Local IP Access , 简称为" LIPA" ) 的 HNB能够在初始化 UE消息中, 将 LGW的 IP地址上报给 GPRS服务支持节点( Serving GPRS Support Node , 简称为 "SGSN", 其中通用分组无线服务(General Packet Radio Service ) 简 称为" GPRS" ), 并提供 LIPA使用的 Gi/SGi接口, 以支持使用相关 ID (标 识 )来关联 LGW与 HNB之间的内部用户面通道。
目前, 当 UE发生跨 HNB的切换时, LGW发起 LIPA承载的去激活, 即不支持 LIPA移动性。 如果在 UE切换前不先发起去激活 LIPA承载, 那 么当 UE切换到不支持 LIPA移动性的目标 HNB时, 目标 HNB将为 LIPA 承载准备资源, 从而导致资源浪费。
因而, 需要一种方案能够有效地管理 LIPA承载的切换, 避免资源浪费。 发明内容

本发明的再一方面, 提供了一种家庭基站网关 HNB GW, 该家庭基站 网关包括: 第一接收模块, 用于接收源家庭基站 HNB发送的用于请求切换 本地 IP访问 LIPA承载的第一切换请求消息; 确定模块, 用于根据该第一 接收模块接收的该第一切换请求消息, 确定目标 HNB是否支持 LIPA移动 性, 以进行相应的切换操作。
本发明的再一方面, 提供了一种家庭基站 HNB, 该家庭基站包括: 第 一发送模块,用于向目标家庭基站网关 HNB GW发送用于请求切换本地 IP 访问 LIPA承载的第一切换请求消息; 接收模块, 用于在该目标 HNB GW 根据该第一发送模块发送的该第一切换请求消息, 确定目标家庭基站 HNB 不支持 LIPA移动性时,接收该目标 HNB GW发送的用于指示 LIPA承载切 换失败的切换失败消息。

S110,接收源家庭基站 HNB发送的用于请求切换本地 IP访问 LIPA承 载的第一切换请求消息。
S120, 根据该第一切换请求消息, 确定目标 HNB是否支持 LIPA移动 性, 以进行相应的切换操作。
为了有效地管理 LIPA承载的切换,目标 HNB GW可以接收 HNB发送 的第一切换请求消息, 该第一切换请求消息用于请求切换 LIPA承载, 目标 HNB GW根据该第一切换请求消息,确定目标 HNB是否支持 LIPA移动性, 以进行相应的切换操作。 应理解, LIPA承载通常指接收或发送本地业务的 承载, 例如, LIPA承载包括非接入层的承载、 无线承载等, 该非接入层的 承载可以包括包数据协议(Packet Data Protocol, 简称为 "PDP" ) 内容等。
因此, 本发明实施例的切换承载的方法, 通过目标 HNB GW确定目标 HNB是否支持 LIPA移动性, 并釆取相应的切换操作, 从而能够有效地管 理 LIPA承载的切换, 节省资源和信令, 并避免不支持 LIPA移动性的 HNB 为 LIPA承载准备资源而导致的资源浪费和无效的信令开销。
应理解,当 UE在 HNB GW下的 HNB之间进行切换时,目标 HNB GW 也是源 HNB GW。
在 S 110中, 目标 HNB GW接收 HNB发送的第一切换请求消息。
例如, 该第一切换请求消息用于请求切换 LIPA承载, 并且该第一切换 请求消息可以为增强的无线网络子系统应用部分( Radio Network Subsystem Application Part, 简称为 "RNSAP" )切换请求( Relocation Request )。
在本发明实施例中, 可选地, 该第一切换请求消息包括连接该源 HNB 的本地网关 LGW所在的本地网络的标识、 该 LGW的标识、 该 LGW的地 址以及用于请求切换 LIPA承载的请求信息中的至少一种。 可选地 , 该第一切换请求消息包括连接源 ΗΝΒ的 LGW所在的本地网 络的标识、 LGW的标识和 LGW的地址中的至少一个, 以隐式地指示该消 息用于请求切换 LIPA承载。 目标 HNB GW可以根据上述信息确定源 ΗΝΒ 请求切换 LIPA承载。 例如, 该本地网络的标识为 LHN-ID; 该 LGW的标 识例如为 LGW-ID ; 该 LGW 的地址例如为 LGW 在本地网域的地址 LGW@LN地址 , 或 LGW在核心网域的地址 LGW@CN地址 , 该 LGW的 地址还可以是 LGW与 HNB之间的控制面地址或用户面地址, 或该 LGW 的地址还可以是 LGW与源 HNB GW之间的控制面地址或用户面地址。
该第一切换请求消息还可以包括显式的请求信息。 例如, 该第一切换 请求消息包括用于请求切换 LIPA承载的请求信息。 目标 HNB GW可以根 据该请求信息, 确定源 HNB请求切换 LIPA承载, 进而可以进一步确定目 标 HNB是否支持 LIPA移动性。
在 S120中, 目标 HNB GW确定目标 HNB是否支持 LIPA移动性, 可 以包括确定目标 HNB是否支持 LIPA, 以及确定目标 HNB是否能够与连接 源 HNB的 LGW建立 LIPA连接。 由此目标 HNB GW可以根据目标 HNB 是否支持 LIPA移动性的结果, 进行相应的切换操作。
目标 HNB GW收到第一切换请求消息后, 可以根据源 HNB和 /或目标 HNB上报的信息或网管配置的信息,确定目标 HNB是否支持 LIPA移动性。 可选地, 在本发明实施例中, 目标 HNB GW根据目标 HNB和源 HNB是否 位于同一本地网络,或根据目标 HNB是否能够与已经和源 HNB建立 LIPA 承载的 LGW建立 LIPA承载, 确定目标 HNB是否支持 LIPA移动性。
例如,目标 HNB GW可以根据目标 HNB和源 HNB位于同一本地网络 , 确定目标 HNB支持 LIPA移动性; 再例如, 目标 HNB GW可以根据目标 HNB和源 HNB不位于同一本地网络,确定目标 HNB不支持 LIPA移动性。 再例如,目标 HNB GW可以根据目标 HNB能够与已经和源 HNB建立 LIPA 承载的 LGW建立 LIPA承载, 确定目标 HNB支持 LIPA移动性; 再例如, 目标 HNB GW可以根据目标 HNB不能够与已经和源 HNB建立 LIPA承载 的 LGW建立 LIPA承载 , 可以确定目标 HNB不支持 LIPA移动性。
例如, 目标 HNB GW收到第一切换请求消息后, 可以通过查找本地存 储的 HNB信息表, 确定目标 HNB和源 HNB所位于的本地网络 ID, 并通 过比较目标 HNB和源 HNB所位于的本地网络 ID是否相同,确定目标 HNB 是否支持 LIPA移动性。 又例如, 目标 HNB GW可以根据 HNB信息表, 分 别查找能够与目标 HNB和源 HNB建立 LIPA承载的 LGW, 并确定相应的 LGW是否相同, 以确定目标 HNB是否支持 LIPA移动性。
因此, 本发明实施例的切换承载的方法, 通过目标 HNB GW确定目标 HNB是否支持 LIPA移动性, 并釆取相应的切换操作, 从而能够有效地管 理 LIPA承载的切换, 节省资源和信令, 并避免不支持 LIPA移动性的 HNB 为 LIPA承载准备资源而导致的资源浪费和无效的信令开销。

具体而言,当 UE在 HNB GW下的 HNB之间进行切换时 ,目标 HNB GW 也是源 HNB GW,此时, 目标 HNB GW可以接收源 HNB发送的配置信息, 该配置信息包括该源 HNB支持 LIPA的能力信息和 /或连接 LGW的连接信 息; 该目标 HNB GW也可以接收目标 HNB发送的配置信息, 该配置信息 包括该目标 HNB支持 LIPA的能力信息和 /或连接 LGW的连接信息。当 UE 在不同 HNB GW下的 HNB之间进行切换时 ,目标 HNB GW接收目标 HNB 发送的配置信息, 该配置信息包括该目标 HNB支持 LIPA的能力信息和 /或 连接 LGW的连接信息。 应理解, 支持 LIPA的能力指 HNB是否能够通过 LGW进行本地 IP访问或业务卸载的能力, 该 LGW的地址可以是 LGW在 本地域的地址,也可以是在核心域的地址, 并且该 LGW的地址可以是控制 面的地址, 也可以是用户面的地址。
因此, 目标 HNB GW可以根据源 HNB和 /或目标 HNB发送的配置信 息, 确定目标 HNB是否支持 LIPA移动性, 以进行相应的切换操作。 例如, 在本发明实施例中, 当目标 HNB GW确定目标 HNB支持 LIPA移动性时, 目标 HNB GW将源 HNB发送的第一切换请求发送给目标 HNB, 从而目标 HNB可以根据目前的切换 LIPA承载的流程, 进行 LIPA承载的切换。 当目 标 HNB GW确定目标 HNB不支持 LIPA移动性时 , 目标 HNB GW可以拒 绝该切换请求, 也可以删除切换请求中包含的 LIPA承载的相关信息, 并继 续非 LIPA承载的切换。 下面将结合图 4和 5, 对上述两种情况分别进行描 述。
如图 4所示, 可选地, 根据本发明实施例的切换承载的方法 100还可 以包括: S140 , 目标 HNB GW在确定该目标 HNB不支持 LIPA移动性时 , 向该源 HNB发送用于指示 LIPA承载切换失败的切换失败消息。
可选地, 该切换失败消息包括指示信息, 该指示信息用于指示该目标 HNB不支持 LIPA移动性。
在本发明实施例中, 源 HNB收到切换失败消息后, 源 HNB可以通知 SGSN或与源 HNB连接的 LGW发起 LIPA承载的去激活, 源 HNB GW也 可以通知 SGSN或 LGW释放或去激活 LIPA承载。
因此, 如图 4所示, 该方法 100还可以包括: S150, 目标 HNB GW在 确定该目标 HNB不支持 LIPA移动性时, 通知 GPRS服务支持节点 SGSN 或 LGW释放 LIPA承载。
在本发明实施例中,当目标 HNB GW确定目标 HNB不支持 LIPA移动 性时, 目标 HNB GW也可以删除切换请求中包含的 LIPA承载的相关信息, 并继续非 LIPA承载的切换。 如图 5所示, 根据本发明实施例的该方法 100 还可以包括: S160, 目标 HNB GW在确定该目标 HNB不支持 LIPA移动性 时, 向该目标 HNB发送第二切换请求消息, 该第二切换请求消息仅包括与 非 LIPA承载相关的信息。
如图 5所示, 根据本发明实施例的该方法 100还可以包括: S170, 目 标 HNB GW在非 LIPA承载的切换完成后, 向 GPRS服务支持节点 SGSN 发送切换完成消息, 以使得该 SGSN根据该切换完成消息释放 LIPA承载。
在 S160中, 目标 HNB GW可以删除从源 HNB收到的第一切换请求消 息中的 LIPA承载相关的信息, 使得只包含非 LIPA承载相关的信息, 并向 该目标 HNB发送第二切换请求消息,该第二切换请求消息仅包括与非 LIPA 承载相关的信息,不包括该第一切换请求消息中的与 LIPA承载相关的信息, 从而只切换非 LIPA承载。

在本发明实施例中, LIPA承载的切换包括不跨 HNB GW的切换, 以 及跨 HNB GW的切换。 其中, 不跨 HNB GW的切换指 UE在 HNB GW下 的 HNB之间进行切换 , 当源 HNB和目标 HNB之间有直接接口 Iurh时 , 源 HNB发送的切换消息的路径只经过源 HNB、 HNB GW和目标 HNB。 而 跨 HNB GW的切换指 UE在不同 HNB GW下的 HNB之间进行切换, 这种 切换一定需要核心域参与, 源 HNB发送的切换消息的路径经过源 HNB、 源 HNB GW、 CN域、 目标 HNB GW和目标 HNB。
