Method and system for seamless roaming between wireless communication networks with a mobile terminal

A method of wireless data communication within a mobile computer terminal, said method comprising:

• establishing a wireless connection with a cellular wireless communication network via a first wireless interface directly coupled to the mobile computer terminal;
• establishing a wireless connection with a wireless local area network via a second wireless interface directly coupled to the mobile computer terminal, the wireless connection with the local area network enabled concurrently with the wireless connection with the cellular wireless communication network;
• routing data between the mobile computer system and the cellular wireless communication network via the first wireless interface;
• and
• seamlessly handing-off data from the cellular wireless communication network via the first wireless interface to the wireless local area network via the second wireless interface in response to said mobile computer terminal having a higher bandwidth connection to the wireless local area network than to the cellular wireless network.

A computer usable medium that stores a plurality of software instructions for execution by a mobile computer terminal to support seamless roaming of a mobile computer terminal between wireless communication networks, said computer usable medium comprising:

• a plurality of instructions that are executable by the mobile computer terminal to support simultaneous wireless connections between the mobile computer terminal and a cellular wireless communication network via a first wireless interface directly coupled to the mobile computer terminal and a wireless local area network via a second wireless interface directly coupled to the mobile computer terminal;
• a plurality of instructions that are executable by a network access arbitrator of the mobile computer terminal to cause the network access arbitrator to route data communicated between the mobile computer terminal and the cellular wireless communication network and the wireless local area network, wherein said network access arbitrator routes said data to the cellular wireless communication network via the first wireless interface;
• and
• wherein the network access arbitrator seamlessly hand-off said data from said cellular wireless communication network via the first wireless interface to the wireless local area network via the second wireless interface in response to said mobile computer terminal having a higher bandwidth connection to the wireless local area network than to the cellular wireless network.
