Device and method for transporting and converting protocol messages from one protocol into another
First Claim
1. A device for transporting a protocol message comprising:
- a non-ISDN protocol processor for converting a message in a non-ISDN protocol data format into a message in its own protocol data format;
an interfacing part for converting the message from the non-ISDN protocol processor into a message in a User to User Signaling (UUS) service message format; and
a UUS service part for transferring the message in the UUS service message format to a Private Exchange (PX).

Abstract
Device and method for transporting a protocol message, which permits PBXs (Private Branch Exchanges) connected through a PX(Public Exchange) or PX subscriber stations to transport a new protocol message between end terminals thereof through a PX, the device including a non-ISDN protocol processor for converting a message in a non-ISDN protocol data format into a message in its own protocol data format, an interfacing part for converting the message from the non-ISDN protocol processor into a message in a UUS service message format, and a UUS service part for transferring the message in the UUS service message format to a PX, thereby permitting a message transmission/reception between PBX subscribers or PX subscribers even if a communication protocol the PX gives no support.

8. A method for transporting a protocol message comprising:
-
converting a message in a non-ISDN protocol data format into a message in an ISDN UUS service message format, if the message in a non-ISDN protocol data format is produced at a PBX or a PX subscriber station;
converting a message in a non-ISDN protocol data format into a message in its own protocol data format if required to support communication; and
transferring the message in an ISDN UUS service message format to a PX. - View Dependent Claims (9, 10, 11)

12. A method for transporting a protocol message by using a PBX or a PX subscriber station having a non-ISDN protocol processor, an interfacing part, and a UUS service part, comprising:
-
(1) the non-ISDN protocol processor converting a message in a non-ISDN protocol data format into a message in a protocol message format for a destination side PBX or the PX subscriber station;
(2) the interfacing part converting the protocol message into a message in an ISDN UUS service message format; and
(3) the UUS service part transferring the ISDN UUS service message to a PX. - View Dependent Claims (13, 14, 15, 16)
the PX transferring the ISDN UUS service message to a destination side station;
the destination side station transferring a call release message to the PX by using an ISDN protocol UUS service 2;
the PX transferring the call release message to the interfacing part in the originating side PBX after the step (3).

16. A method as claimed in claim 12, after the step (3), further comprising:
-
the PX transferring the UUS service message to a UUS service part in the destination side PBX or the PX subscriber station;
the destination side UUS service part transferring the UUS service message to the interfacing part in the destination side PBX or in the PX subscriber station;
the destination side interfacing part converting the UUS service message into a message format of the destination side non-ISDN protocol processor;
the interfacing part transferring the converted non-ISDN protocol message to the non-ISDN protocol processor in the destination side PBX or PX subscriber station; and
the destination side non-ISDN protocol processor converting the non-ISDN protocol message into a data format for the destination side PBX or PX subscriber station, and transferring to a call processor in the destination side PBX or in the PX subscriber station.
