    • Systems, methodologies, and devices are described that enable communication devices, such as mobile devices, to efficiently connect and communicate with public data networks (PDNs) even if overlapping Internet protocol address spaces exist in the PDNs. The subject innovation can employ virtual home agents (v-HAs) that can respectively serve PDNs. To facilitate connection of a mobile device to a desired PDN, a message, including an identifier relating to the desired PDN, can be transmitted to a v-HA and it can be discovered whether that v-HA serves the desired PDN; if so, the v-HA transmits the message to a “home” home agent (h-HA) associated with the desired PDN; and if not, the v-HA can transmit a switch message indicating the correct v-HA to which the message should be sent. Concatenation of communication tunnels associated with the correct v-HA and h-HA facilitate efficient communication associated with the mobile device and desired PDN.
    • 描述了即使在PDN中存在重叠的因特网协议地址空间的情况下,能够使诸如移动设备之类的通信设备有效地连接和与公共数据网络(PDN)通信的系统,方法和设备。 主题创新可以采用可以分别提供PDN的虚拟归属代理(v-HA)。 为了便于移动设备到期望的PDN的连接,可以将包括与期望的PDN相关的标识符的消息发送到v-HA,并且可以发现该v-HA是否服务于期望的PDN; 如果是,则将该消息发送到与期望的PDN相关联的“家庭”归属代理(h-HA); 如果不是,则v-HA可以发送指示消息应该被发送到的正确的v-HA的交换机消息。 与正确的v-HA和h-HA相关联的通信隧道的并入促进了与移动设备和期望的PDN相关联的有效通信。
