However, the guide according to the present invention additionally supports information messages used for the purpose of transmitting an incoming digit or displaying purposes in addition to the above messages in the S-Card.

In addition, the information support functions include call hold, call transfer, multi-call, night service, adjacent extension call, relay of incoming call rejection subscribers, call storage, call forwarding, call waiting, call assignment, forced cutting, etc. It is not possible for the guide to request and establish all of the above functions with the limited messages described above. Therefore, in the present invention, the communication between the guide and the network is used as a message used for establishing, connecting, and releasing the call, and distinguishes each function by transmitting a predetermined code predetermined using the receiver number information and the display information of the information message. And treatment.

1 illustrates a connection relationship between a guide and an exchange period according to an embodiment of the present invention.

First of all, in the Windows 113 environment, an S-Card (S-Card) and a CAPI 114 for matching with the upper guide program 115 are used. That is, the guide 111 is provided with the CAPI114, and if the PC using the Windows 113 can be used as the guide 111 by installing the guide program 115. In addition, the exchange 112 connects the BRIC board 116 to which a general digital subscriber is directly connected, and the SSCC board 117 and ANDP (Access) to connect the upper application DCC (Digital Circuit Control Block). Network Device Processor (ENDP) 118.

Here, the guide 111 is connected to the BRIC board of the switch 112 through NT (Network Termination) 120 like a general BRIC digital subscriber, and between the guide 111 and the switch 112 is a Q.931 protocol (protocol). Messages are transmitted and received and various function processing is performed.

Hereinafter, an operation process according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram illustrating a process of establishing and releasing a guide 111 signal according to a Q.931 message flow between the guide 111 and the switch 112 according to an embodiment of the present invention.

First, when the guide 111 transmits a setup message to the switch 112 in step 211, the switch 112 checks the price of the guide 111 line. In this case, if it is determined that the subscriber is a general subscriber, the exchange 112 performs basic call processing as before. If it is determined that the guide 111 is the exchange 112 performs the guide 111 processing.

By the above process, the guide 111 receives the CALL PROCEEDING, ALERTING, and CONNECT signals from the exchange 112 in steps 213 to 217 in turn, and transmits the CONNECT ACKNOWLEDGEF signal to the exchange 112 in step 219 in response. This is the point in time when the connection with the network (exchange 112) is completed from the standpoint of the guide 111.

And once the connection with the network is established, from then on, the information (INFORMATION) message is carried out and the actual call processing and function processing are proceeded. That is, when the guide 111 inserts '01' into the display information element of the information message in step 221 and transmits it to the switch 112, the switch 112 recognizes that it has transmitted a setup for actual transmission and processes the call signal. Will be performed. That is, the exchange 112 likewise sets the recipient number information element of the information message as promised and sends it to the guide 111.

Accordingly, the guide 111 receives the CALL_PROC, ALERTNG, and CONNECT signals in sequence from the switch 112 in steps 223 to 227 by the action of the switch 112. The guide 111 transmits CONN_ACK in response to the messages in step 229, where the guide 111 enters a busy state with the called subscriber.

Thereafter, when the guide 111 presses the release key, the process proceeds to step 237. When the called subscriber recovers the call, the process proceeds to step 231.

First, when the called subscriber recovers the call, the guide 111 receives the DISCONNECTF signal using the information message from the switch 112 in step 231, and the guide 111 transmits a RELEASE signal in step 233. In step 235, the REL_COMP signal is received from the exchange 112 to perform the release process.

The guide 111, which proceeds to step 237 by inputting the release key of the guide 111, transmits a DISCONNECT signal using an information message to the switch 112, receives a RELEASE signal in step 237, and receives REL_COMP in step 241. Performing the release process by transmitting.

When the release process is completed, the guide 111 receives a DISCONNECT signal for disconnecting from the switch 112 in step 243. The guide 111 responds with a RELEASE signal in step 245, and a RELEASE COMPLETE signal in step 247. Receives and releases the connection completely and returns to the idle state.

An example of the code list defined by the information message is shown in Table 1 below.

code Defined meaning code Defined meaning One SETUP 18 HOSTORE ACCEPT 2 CALL PROCEEDING 19 Transfer REQUEST 03 ALERTING 20 Multi-Currency REQUEST 04 CONNECT 21 Adjacent call REQUEST 5 CONNECT ACKNOWLEDGE 22 Incoming Status REQUEST 6 DISCONNECT 23 Requisition REQUEST 7 RELEASE 24 DND Break REQUEST 8 RELEASE COMPLETE 25 TEST MESSAGE 9 INFORMATION 26 Head set status 10 HOLD 27 Relative Subscriber Release REPORT 11 HOLD ACKNOWLEDGE 28 REQUEST REQUEST WITH Pending Subscriber 12 HOLD REJECT 29 CTR-DND Break REQUEST 13 RETRIEVE 30 Call Waiting REQUEST 14 RETRIEVE ACKNOWLEDGE 31 Force cutting REQUEST 15 RETRIEVE REJECT 32 Resend ACCEPT 16 Guide RESET 33 Multicall Subscriber Release REQUEST 17 REPORT STORAGE REPORT

As described above, the present invention supports the CAPI drive and installs the guide 111 program on a PC using Windows, and thus can be used as the guide 111 to reduce the time and cost of making the guide 111 newly. In addition, it has great advantage in terms of compatibility and flexibility because only the message processing part of the information application 111 and the application of the network need to be modified without any hardware change when adding or changing a function.
