Abstract
A session integration method is provided for integrating a first session between a first entity and a third entity and a second session between a second entity and the third entity in a session-based service environment. The first entity receives a REFER message including dialog information from the second entity, and sends a response message to the received REFER message to the second entity. When header information included in the received REFER message indicates an INVITE message and the dialog information is related to the first entity, the first entity generates a Re-INVITE message and sends the generated Re-INVITE message to an address of a target which is subject to session integration. The address is included in the header information and corresponds to the third entity. The first entity updates the first session into an integrated session with the third entity.
