IP INTER-WORKING GATEWAY IN NEXT GENERATION NETWORK AND METHOD FOR IMPLEMENTING INTER-WORKING BETWEEN IP DOMAINS
First Claim
1. An Internet Protocol (IP) inter-working gateway in a Next Generation Network (NGN), comprising:
- a transport layer module which complies with the definition of a standard Transmission Control Protocol/Internet Protocol (TCP/IP) protocol stack, for determining a service type of an IP packet from a source IP domain, and transmitting the IP packet to a service module or to a destination IP domain;
the service module, for performing processing of signalling proxy, Real Time Transport Control Protocol (RTCP) and media conversion and/or processing of control protocol for the IP packet from the transport layer module, and transmitting the IP packet processed by the service module to the destination IP domain.

Abstract
An IP inter-working gateway in an NGN includes. a transport layer module which complies with the definition of a standard TCP/IP protocol stack, for determining a service type of an IP packet from a source IP domain, and transmitting the IP packet to a service module or to a destination IP domain; the service module, for performing processing of signalling proxy, RTCP and media conversion and/or processing of control protocol for the IP packet from the transport layer module, and transmitting the IP packet processed by the service module to the destination IP domain. The embodiments of the present invention provides a method for implementing inter-working between IP domains by the IP inter-working gateway, which implements the inter-working of IP packet between heterogeneous operating networks.
