Network, private branch exchange, and multi protocol communication terminal control method for use in the exchange
First Claim
1. A network including:
- at least a session initiation protocol (SIP) terminal which performs communication by an SIP for realizing connection type communication to perform the communication while confirming connection to a target in an Internet protocol (IP) network; and
a private branch exchange which performs a call connection process between the terminals, the network comprising;
an SIP system protocol control module incorporated as one of component groups of the private branch exchange and constituted into the module using a mechanism of a back to back user agent (B2BUA) which operates as an acting user agent of a process of the SIP; and
an additional service providing module which is incorporated as one of the component groups of the private branch exchange and which provides additional services of the private branch exchange in response to a key operation of the SIP terminal.

Abstract
There is disclosed a private branch exchange in which an SIP terminal is capable of receiving great variety of services provided by the private branch exchange without upgrading version of software of the SIP terminal itself. A standard SIP protocol control module 16, an expanded SIP protocol a control module 17, and an expanded SIP protocol b control module 18 are disposed for SIP system protocol corresponding terminals, convert signals (requests) from the SIP system protocol corresponding terminals into signals of a protocol inside an IP-PBX 1 to transmit the signals to a PBX basic connection process providing module 12, and convert a signal (responses to the request, or a request to the SIP system protocol corresponding terminal) from the PBX basic connection process providing module 12 into a signal of an SIP system protocol to transmit the signal to the SIP system protocol corresponding terminal.

- at least a session initiation protocol (SIP) terminal which performs communication by an SIP for realizing connection type communication to perform the communication while confirming connection to a target in an Internet protocol (IP) network; and
- 7. A private branch exchange which performs a call connection process between terminals, wherein an SIP system protocol control module obtained by constituting a process of a session initiation protocol (SIP) for realizing a connection type communication to perform the communication while confirming connection to a target in an Internet protocol (IP) network into the module using a mechanism of a back to back user agent (B2BUA) which operates as an acting user agent is incorporated as one of component groups.

13. A multi protocol communication terminal control method of a network including:
- at least a session initiation protocol (SIP) terminal which performs communication by an SIP for realizing connection type communication to perform the communication while confirming connection to a target in an Internet protocol (IP) network; and
a private branch exchange which performs a call connection process between the terminals, the method comprising the steps of;
allowing an SIP system protocol control module constituted into the module using a mechanism of a back to back user agent (B2BUA) which operates as an acting user agent and incorporated as one of component groups of the private branch exchange to perform a process of the SIP. - View Dependent Claims (14, 16, 17, 18, 30, 31, 33, 35)
