Further, removing a second codec list in the first encoding from the request for the session, deriving a third codec list, when the user plane gateway is to be removed, from the first codec list, or, when the user plane gateway is not to be removed, from the second codec list, including in the request for the session, a third codec list in the first encoding, and transmitting the request for the session.
