US 2010/0150105 A1 · Apparatus And Method For Splicing Multimedia Session On Communication Networks

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.

Dependent claims

An apparatus for splicing multimedia stream session on communication networks, comprising:

a handoff manager for monitoring whether a mobile host being roaming to other subnets or not, and acquiring a new IP address and issuing a first control signal when a handoff event being triggered during an ongoing session;
a session migration manager, when a media client triggering a migration action, said session migration manager, based on the monitoring status of another ongoing session, sending a state message to a target host for performing session migration, enabling a media player, and issuing a second control signal;
and
a session splice module for respectively receiving said first and second control signals, and performing a corresponding session splicing for each control signal to keep said ongoing session continuous for said mobile host or said media client.
