Hybrid wireless access bridge and mobile access router system and method

摘要

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.
