1. A method of communicating with a correspondent node in a remote network in a communication system supported by IP (Internet Protocol), comprising:
- (a) sending, from a mobile node located in a foreign network, signaling for initialization of a communication session through a first communication path by sending an invite message to said correspondent node via a proxy entity associated with a home network of the mobile node, including sending the invite message via a home agent of the home network to a Proxy Call State Session Function (P-CSCF) of the home network; and
(b) transmitting contents of said communication session straightforwardly from said mobile node to said correspondent node through a second communication path, wherein the second communication path comprises a direct data path between the mobile node and the correspondent node without passing through the proxy entity.

Abstract
In a wireless communications system in which a mobile node seeks a communication session with a correspondent node by first signaling for initialization of the communication session through a first data path via an intermediate node. Thereafter, contents of the communication is established through a second data path in which the mobile node and the correspondent node communicate straightforwardly without going through the intermediate node.

14. An apparatus for communication with a correspondent node in a remote network in a wireless communication system supported by the IP (Internet Protocol), comprising:
-
a memory circuit having computer-readable instructions for, sending from a mobile node located in a foreign network, signaling for initialization of a communication session through a first communication path by sending an invite message to said correspondent node via a proxy entity associated with a home network of the mobile node, including sending the invite message via a home agent of the home network to a Proxy Call State Session Function (P-CSCF) of the home network, and transmitting contents of said communication session straightforwardly from said mobile node to said correspondent node through a second communication path, wherein the second communication path comprises a direct data path between the mobile node and the correspondent node without passing through the proxy entity; and a processor circuit coupled to said memory circuit for processing said computer-readable instructions. - View Dependent Claims (15, 16, 17, 18, 19)
