Abstract
The present invention relates to an apparatus and method for splicing multimedia session on communication networks. The apparatus comprises a handoff manager, a session migration manager and a session splicing module. The handoff manager monitors whether a mobile host is roaming to other subnets or not, and acquires a new IP address and issues a control signal when a handoff event is triggered. When a user triggers a migration action, the session migration manager, based on the monitoring status of an ongoing session, sends a state message to a target host for performing session migration, enables a media player, and issues another control signal. The session splicing module respectively receives the two control signals, and performs a corresponding session splicing for each control signal to persist session connection.
