FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication systems with a plurality of communication session components, e.g. voice #1, video #2 (face-to-face of users) and video #3 (demonstration video) component. In a multimedia communication session with multiple multimedia data components, e.g., in an IP multimedia subsystem, one or more multimedia data components can be transmitted from one access network to another access network and maintain continuity of the entire communication session regardless of that. For this purpose, each session is identified, followed by the identification of the multimedia data component intended for transmission. The identity of the identified session and component are forwarded to one or more elements within the communication network for transmitting the multimedia data component.
EFFECT: providing a system for the reliable transmission of communication session components in order to maintain the communication session continuity.
