Abstract: The present invention provides systems and methods that allow mobile devices, such as PDAs, mobile telephones, and laptops to roam seamlessly between subnets of a mobile wireless network and communicate through the network with local mobile devices and/or Internet sites without having to acquire a new or temporary Internet Protocol (IP) address. The network enables a wireline IP router to support wireless mobile devices. The network performs real-time soft-roaming to enable instantaneous connectivity of a visiting mobile device. Specifically, the network relies on the subnets to share IP addresses of the mobile devices.
