1. A method operable by a first user equipment in a communication system, comprising:
- receiving a session identification for a multi-component communication session from an assigning network entity;
establishing the multi-component communication session with a second user equipment via a first access network, the multi-component communication session including a plurality of session components;
identifying a component from the plurality of session components as an identified component for transfer;
sending the session identification to the network entity via a second access network for transfer of the identified component from the plurality of session components from a first path including the first user equipment, the first access network and the second user equipment to a second path including the first user equipment, the second access network and the second user equipment, wherein the first user equipment maintains at least one session component from the plurality of session components with the first access network;
providing information of the identified component to the network entity for the transfer of the identified component from the multi-component communication session;
providing the network entity a designated value for the identified component as the information of the identified component, wherein the designated value is derived from an order of listing of the plurality of session components in a session initiation protocol message, and wherein session initiation protocol messages for the multi-component communication session always maintain the same order of listing of the plurality of session components; and
providing information of a component not being transferred from the plurality of session components to the network entity.

Abstract
In a multimedia communication session with multiple media components, one or more media components can be transferred from one access network to another access network and yet maintain the continuity of the overall communication session. Each session is first identified and thereafter the media component intended to be transferred is also identified. The identities of the identified session and component are sent to one or more entities within the communication network for executing the media component transfer.
