Patent ID: 7821995

Claim:
A method for seamless active session migration of a reliable protocol session from a source Base-Station-Router (BSR) to a target BSR in a wireless IP network, comprising: decoupling at said source BSR said reliable protocol session served by said source BSR into a forward-link state and a reverse-link state, wherein said forward-link state comprises forward-link state data of said reliable protocol session and said reverse-link state comprises reverse-link state data of said reliable protocol session; and migrating separately said forward-link state and said reverse-link state from said source BSR to said target BSR, wherein upon completion of the migrating, said target BSR is operable to serve said reliable protocol session, wherein said source BSR and said target BSR are components of a distributed cellular network and said source BSR and said target BSR are adapted to serve as a primary agent and a secondary agent.
