To date, 3GPP2 has shown the "ALL-IP NAM (Network Architecture Model) Version 1.0.0" as shown in Figure 1, based on this, divided into each TSGs (Technical Study Group) of 3GPP2 by field to continue the standard work Due to this, there may be changes in the specification in the future.

Looking at the ALL-IP NAM (Network Architecture Model) presented so far, as shown in Figures 2 and 3, the signal is transmitted to the Internet Protocol Multimedia (IPMM: Domain) Domain (2a) and TIA / EIA- It is divided into 41 domains (2b). IPMM domain (2a) is a part that processes messages using IP, and TIA / EIA-41 domain (2b) is a part that processes existing messages as they are. to be.

In order to process such different domains and messages, an option that can be selected in a message is required. Currently, this is not defined in the IOS standard or the IS-2000.

Therefore, a method for dividing a message by domain in an ALL-IP network is required.

The present invention has been proposed in response to the above-described needs, and is a domain distinguishing device for distinguishing a connection request message of a terminal for each domain in an integrated internet protocol (ALL-IP) network, etc. and a message delivery method using the same. And a computer readable recording medium having recorded thereon a program for realizing the above method.
