Referring to FIGS. 3 to 4, a call processing procedure of the trunk gateway apparatus using the LTE radio access module according to the present invention will be described. I would like to explain how the call progresses.

First, when an IP subscriber dials to perform number translation and a called subscriber is determined, if an incoming subscriber occupancy request (S101) is transmitted from the call processing module (not shown) to the trunk gateway (TGW) In accordance with the occupancy request, the PABX digital trunk requests a subscriber setup (S102). In contrast, in the PABX digital trunk, the setup ACK (S104) is notified to the trunk gateway (TGW) device of the LTE radio access module through the signal transmission / reception unit.

Thereafter, the PABX digital trunk transmits an Alerting message (S105) to the trunk gateway (TGW) device of the LTE radio access module through the signal transmitting and receiving unit, and the call processing module notifies the calling IP phone subscriber of the call reception. In this case, the incoming general subscriber is transmitting the ring signal, and the originating IP subscriber hears Ring Back Tone.

When the called subscriber responds to the handset in the above state, a 200K (S108) message indicating that the called party's response has been answered is transmitted from the trunk gateway (TGW) device of the LTE radio access module to the call server. The call between the general subscriber and the IP subscriber is set according to the transmission of the ACK message (S109) of the call server.

The outgoing call by the general subscriber according to the present invention can proceed with the call processing according to the same processing if the call request procedure is reversed to the IP subscriber of the call server through the trunk gateway (TGW) apparatus of the LTE radio access module .

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored.

Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) .

The computer readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers skilled in the art to which the present invention pertains.

As described above, preferred embodiments of the present invention have been disclosed in the present specification and drawings, and although specific terms have been used, they have been used only in a general sense to easily describe the technical contents of the present invention and to facilitate understanding of the invention , And are not intended to limit the scope of the present invention.
