An active session mobility solution for point-to-point protocol (PPP) in accordance with the present invention provides fast and smooth handoff by reducing tunneling overhead on tunneling mechanisms, such as P-P tunneling from a serving Source (e.g., a PPP termination device) to a new serving Target (e.g., a PPP termination device). In the active session mobility solution of the present invention, PPP session can be migrated even if not all phases have been completed (e.g., LCP, PAP/CHAP completed but not IPCP and CCP). In such cases, the incomplete phases will be negotiated at the PPP of the Target PPP.

The invention comprises a method and apparatus for providing multimedia content to a calling party device. Specifically, the method comprises receiving a connection establishment request from a calling party device where the connection establishment request is operable for establishing a connection between the calling party device and a called party device in an Internet Protocol (IP) Multimedia Subsystem (IMS) network, obtaining multimedia content information in response to the connection establishment request where the multimedia content information is operable for establishing at least one multimedia session with the calling party device, and transmitting at least a portion of the multimedia content information towards the calling party device contemporaneously with establishment of the connection.
