    • A method for routing data packets to a mobile node in a communication system which includes at least a first subnetwork of a first type supporting a first IP version and a second subnetwork of a second type supporting a second IP version. The mobile node is provided with a set of protocol stacks for handling data packets at least according to the first and the second IP version and with a home address at least according to the first and the second IP version. The home agent intercepts at least data packets addressed to the mobile node's home address according to the first or the second IP version and for encapsulating a data packet addressed to the mobile node in a packet according to the IP version of the foreign network to which the mobile node is attached, for routing the data packet to the mobile node.
    • 一种用于将数据分组路由到通信系统中的移动节点的方法,该通信系统包括支持第一IP版本的第一类型的第一子网络和支持第二IP版本的第二类型的第二子网络的至少第一子网络。 移动节点具有至少根据第一和第二IP版本以及至少根据第一和第二IP版本的归属地址来处理数据分组的一组协议栈。 归属代理至少截取根据第一或第二IP版本寻址到移动节点的归属地址的数据分组,并根据外部网络的IP版本封装寻址到移动节点的分组中的数据分组, 附加移动节点,用于将数据包路由到移动节点。
