  • Method and apparatus for a dual connection communication session
    Patent number: 6470390
    Abstract: A method and apparatus establishes a connection for a communication session between two remote devices, then negotiates an additional connection. One of the connections is used to communicate data, not commands, allowing that connection to be more efficient because each remote device does not have to scan it for commands in the information it receives.
