SESSION TRANSFER METHOD AND METHOD FOR SUPPORTING SESSION CONTINUITY

摘要

A method for supporting session continuity for a terminal in a server. The method according to one embodiment includes sending, by a server, a session continuity operator policy to a first terminal. The session continuity operator policy includes a parameter indicating a preferred network for a transfer of the ongoing session, and session continuity level information including one of a first level and a second level. The method according to the embodiment further includes receiving, by the server, a first session invite message for one of full media transfer and partial media transfer, unless the session continuity level information of the session continuity operator policy is the second level and the first terminal decides not to start the session transfer; and sending, by the server, a second session invite message to the second terminal to achieve session continuity with the first terminal after receiving the first session invite message.

1. A method for supporting session continuity for a terminal in a server, the method comprising:
sending, by a server, a session continuity operator policy to a first terminal which is engaged in an ongoing session with a second terminal, wherein the session continuity operator policy includes a parameter indicating a preferred network for a transfer of the ongoing session, and session continuity level information including one of a first level indicating that the first terminal starts a session transfer to a preferred network and a second level indicating that starting of the session transfer is performed based on a decision of the first terminal, and wherein the session continuity operator policy is considered by the first terminal to determine whether to transfer full or partial media; receiving, by the server, a first session invite message for one of full media transfer and partial media transfer from the first terminal via a target network within the preferred network, unless the session continuity level information of the session continuity operator policy is the second level and the first terminal decides not to start the session transfer, and sending, by the server, a second session invite message to the second terminal to achieve session continuity with the first terminal after receiving the first session invite message from the first terminal.
