Multimedia communication using co-located care of address for bearer traffic

An apparatus in a wireless communication system, comprising:

• means for acquiring first source address and second source address of a mobile node located in a foreign network, wherein the first source address is a home address of the mobile node in a home network and the second source address is a co-located care-of address of the mobile node in the foreign network;
• means for signaling, using said first source address, a request to the home network to initialize a communication session between the mobile node in the foreign network and a correspondent node located in a remote network;
• and
• means for transmitting, from the foreign network to the remote network, contents of said communication session to the correspondent node using said second source address.

An apparatus in a communication system, comprising:

• a memory circuit having computer-readable instructions for
• acquiring first source address and second source address of a mobile node located in a foreign network, wherein the first source address is a home address of the mobile node in a home network and the second source address is a co-located care-of address of the mobile node in the foreign network,
• signaling, using said first source address, a request to the home network to initialize a communication session between the mobile node in the foreign network and a correspondent node located in a remote network, and
• transmitting, from the foreign network to the remote network, contents of said communication session to the correspondent node using said second source address;
• and
• a processor circuit coupled to said memory circuit for processing said computer-readable instructions.

A Non-transitory computer-readable medium comprising computer-executable instructions for:

• acquiring first source address and second source address of a mobile node located in a foreign network, wherein the first source address is a home address of the mobile node in a home network and the second source address is a co-located care-of address of the mobile node in the foreign network;
• signaling, through a first communication path using said first source address, a request to the home network to initialize a communication session between the mobile node in the foreign network and a correspondent node located in a remote network;
• and
• transmitting contents of said communication session through a second communication path to the correspondent node using said second source address, wherein the second communication path runs between the foreign network to the remote network.
