摘要： Multiple home agents for a home agent service provider network are implemented in a single computing platform in software as multiple virtual home agents. Each home agent is assigned or dedicated to a single virtual private network. Any number of home agents can be realized in the computing platform by multiple instantiations of a home agent program or code, and by providing unique IP addresses for each instantiation. Each home agent runs independently, and is independently configured and managed by the subscriber of the virtual private network service, freeing the service provider of having to manage and supervise low level processing tasks and customization features that the subscribers may want. In a representative embodiment, the computing platform comprises a router having a general purpose-computing platform.

摘要翻译： 用于家庭代理服务提供商网络的多个家庭代理在作为多个虚拟归属代理的软件中的单个计算平台中实现。 每个归属代理被分配或专用于单个虚拟专用网络。 通过家庭代理程序或代码的多个实例，以及通过为每个实例化提供唯一的IP地址，可以在计算平台中实现任何数量的归属代理。 每个归属代理独立运行，并由虚拟专用网服务的用户独立地配置和管理，使服务提供商不必管理和监督用户可能想要的低级处理任务和定制特征。 在代表性的实施例中，计算平台包括具有通用计算平台的路由器。

摘要： A method is described of automatically locating and connecting a mobile wireless communications device to a packet-switched network such as the Internet. An Internet Protocol (IP) packet from a terminal on the network, destined for receipt by the mobile device, is received at a home agent acting as a gateway or router linking the packet switched network to a second network, such as LAN, coupled to a wireless communications network. The home agent transmits an access-request message to an authentication server. The access-request message includes a destination IP address associated with the mobile device found in the IP packet. The authentication server responsively issues an access-accept message to the home agent if the mobile device is authorized to receive the IP packet. The access-accept message comprises (a) information uniquely identifying said device, such as the IMSI/ESN number for the device, and (b) information identifying a network to use to locate said device. The home agent issues a message containing the information uniquely identifying the device to a mobile node location server. The mobile node location server maintains a table mapping IP addresses for a plurality of mobile communication devices to information uniquely identifying the devices. In the event that the mobile node location server does not find an IP address for the device in the table, the device is paged via the wireless communications network. In response to the page, the mobile device dials into the wireless communications network and second network and initiates a connection to the packet switched network whereby the IP packet is transmitted to the device.
