Abstract
The present invention uses a message with a suspend/resume flag setting sent to the local mobility anchor from the foreign agent that was supporting downlink transmissions to the mobile node. Namely, a transient binding option is proposed for creating a transient BCE state at the home agent/local mobility anchor during an inter-MAG handover, which will suspend down-link traffic from the home agent/local mobility anchor until the transient BCE (suspend) state is cleared by the foreign agent previously supporting downlink transmissions. After the transient BCE (suspend) state is cleared, the downlink traffic from the home agent/local mobility anchor can resume with forwarding of downlink traffic to the mobile node through the foreign agent. The present invention can be implemented using a new protocol application or modified messages from prior registration applications.
