漫游时数据路由方法、互通服务路由器和接入服务路由器
摘要：
本发明提供一种漫游场景下数据路由的方法，包括：归属地互通服务路由器ISR或ASR接收到发送给漫游终端的数据后，获取所述漫游终端的位置信息，所述位置信息包括：所述漫游终端所在拜访地ISR信息，或者，所述漫游终端所在拜访地接入服务路由器ASR信息，所述归属地ISR或ASR将所述数据发送给所述漫游终端的拜访地ISR，或者，将所述数据发送给所述漫游终端的拜访地ASR。本发明还提供一种ISR、ASR和ILR。本发明实现了漫游场景下下行数据的路由。
摘要（英）：

The invention provides a data routing method in a roaming scene. The method comprises the following steps that a home intercommunication service router (ISR) or an ASR receives data sent to a roaming terminal and obtains the position information of the roaming terminal, the position information comprises a roaming terminal visit place ISR information or roaming terminal visit place access service router (ASR) information, and the home ISR or the ASR sends the data to the visit place ISR of the roaming terminal or sends the data to the visit place ASR or the roaming terminal. The invention also provides the ISR, the ASR and an ILR. According to the method, the ISR, the ASR and the ILR, the routing of downlink data in the roaming scene is realized.
