Description

Message transmission service method to subscriber during call at electronic exchange

The present invention relates to a message transmission service method to a subscriber during a call in an electronic switchgear, and more particularly, when a function holder is called by an arbitrary subscriber while the function bearer is in a call. After transmitting the announcement announcement, in response to the announcement announcement, the message inputted from the subscriber is temporarily stored, and when the call of the subscriber possessing the function ends, the corresponding subscriber possessing the function call sends the stored subscriber message. The present invention relates to a message transmission service method to a subscriber during a call in an electronic switching system.

Telecommunication is the transmission of information by selecting two or several persons designated between a plurality of people or devices that are separated from each other. It consists of a terminal device, a transmission line, and a switch. The exchange in charge is the core of telecommunications.

The electronic exchange introduced semiconductor and computer technology into the existing mechanical exchange, enabling the control by accumulation program. Since then, with the phenomenal development of semiconductor and computer, the electronic exchange has created an electronic exchange. ISDN has been made possible.

ISDN is a concept that provides all services in one integrated network, and ISDN exchange will evolve with the structure and function change in stages from existing electronic exchange to accommodate these changes.

On the other hand, if the subscriber registers in the call waiting function provided by the electronic switchboard, when the subscriber is called by any subscriber while the subscriber is busy, the subscriber is notified of the call state. After a call is temporarily held with a subscriber in a call, it is possible to perform a call with a subscriber who was in a call again after finishing a call with a new originating subscriber.

However, in the case of the call waiting function, when a call comes from a random subscriber while the function possessing subscriber is in a call, the function possessing subscriber stops talking with the busy subscriber. FLASH) must be operated to make a call with a new originating subscriber.The subscriber holding the function subscriber and the subscriber who is on the call must hold the handset while the call is being held between the function holder and the originating subscriber. It is possible to continue the call of, but when the call between the calling subscriber and the subscriber holding the function is long, it is frequently necessary to give up the call with the subscriber holding the function halfway.

In addition, the function-bearing subscriber also has to carry out a call with two call counterparts, which involves the inconvenience of having to operate a hook-flash several times during a call, and the original caller who made a call while performing a call with an arbitrary subscriber. If the call recipient of the call abandon the call, there was a problem that the cumbersome, such as having to call again the callee.

Accordingly, the present invention has been made in view of the above circumstances, and when a function holding subscriber is called by any calling subscriber while the function holding subscriber is in a call, the recording guide broadcast is sent to the calling subscriber and then the recording. In response to the announcement, the message entered by the subscriber is temporarily stored, and when the call of the function holder is terminated, the function subscriber can be called to send the stored caller's message to the function holder. The purpose of the present invention is to provide a message transmission service method to subscribers during a call in an electronic exchange.

According to an embodiment of the present invention for realizing the above object, the subscriber A and subscriber B perform a call, the subscriber C calling the subscriber B is in a call, the destination ASP is called by subscriber C Determining whether the called subscriber B is a function possessing subscriber; if the subscriber B is determined to be a function possessing subscriber in the called party's ASP, the ASP sends an IPC message to the GSP to drive the GSI; The recording guide broadcast generated as a result is transmitted to the subscriber C via the call path, the message corresponding to the voice signal from the subscriber C input in response to the recording guide broadcast is recorded to the GSI through the call path Step, the ASP monitors the hook-on state of the subscriber B and if the subscriber B is hooked on, driving the RG to call the subscriber B, the AS P driving the GSI by sending an IPC message to the GSP, and the message stored in the GSI is reproduced and sent to the subscriber B over the call path as the GSI is driven, Provided is a message transmission service method to a subscriber during a call at an exchange.

According to the present invention composed of the above steps, when the function holding subscriber is called by any calling subscriber in the state that the function holding subscriber is in a call, the corresponding electronic exchange sends a recording guide broadcast to the calling subscriber, and the recording guide. In response to the originating subscriber entering a message, the message is temporarily stored in the GSI 36, and when the call of the function possessing subscriber ends, the corresponding function possessing subscriber is called to store the message in the GSI 36. By sending a message, the function-bearing subscriber can check the message from any subscriber after finishing the call.

1 is a block diagram of an electronic switch system to which a message transmission service method is applied to a subscriber during a call according to an embodiment of the present invention, wherein the electronic switch exchange performs an overall function of localized call processing. (10,20), INS 30 performing the overall function of centralized call processing, and three subsystems corresponding to CCS (not shown) performing centralized operation and maintenance functions. .

As shown in the figure, the ASS (10, 20) is a function (BORSCHT) for matching, polarity inversion, PPM transmission, etc. for general subscribers, public telephone subscribers, PBX subscribers under the control of ASIP (5, 25) ASI (1,3,21,23) to perform and 20 [Hz] for sending to the called subscriber under the control of ASIP (5,25), installed correspondingly to the ASI (1,3,21,23) RG (2, 4, 22, 24), which generates a zero crossing (ZC) signal for protecting the call signal current of the circuit and the ring relay of the subscriber line circuit and transmits it to the ASI (1, 3, 21, 23); It performs data processing and control functions required for registration with general analog subscribers, public telephone subscribers and PABX subscribers. , 3,21,23) and LSI (Local Interface) are matched by subhighway while call processing to other subsystems or other exchanges In order to process the traffic through the TSL (6,26) by collectively operating and managing the time-switched switch link (6,26) and the ASS (10,20) that is matched with the INS (30) through the optical link It consists of ASP (7,27) which performs a function.

Here, the LSI processes a dual tone multi-frequency (DTMF) signal from the subscriber and transmits various tones to the subscriber.

In addition, the ASP (7, 27) stores the information on the subscriber registered in the message transmission service to the subscriber during the call of the present invention, the call from any originating subscriber in the state where the specific subscriber is busy If it is determined that the subscriber is a function possessor, it is determined whether the message transmission service is provided to the subscriber during the call under the present invention.

In addition, the INS 30 shown in FIG. 1 has an E / O and an O / E for optical link matching of the ASS 10 and 20 with the TSL 6 and 26. Path change function and space switching function between the CDL 31 performing the data conversion function, the optical clock conversion function, and the data error detection function, and the TSL (6, 26) mutually located at each ASS (10, 20). SSW (32) performing the operation, and connected to the CDL (31) for performing the interprocessor communication (IPC) function between the processor in the ASS (10, 20) and the processor in the INS (30) or CCS Under the control of the HIPCU 33, the INP 34 which performs the search and management function of the call using the SSW 32, the GSP 35, the guide of number change, missed guide, call rejection guide and the present invention During the call, the subscriber to provide the message transmission service is busy, please record the beep and press the star after the recording. A GSI 36 for sending a message to be sent out, and an NTP 38 for responding to the number translation request from the ASPs 7, 27 and performing a route control function.

Here, the GSI 36 temporarily stores a message for the voice signal when the voice signal is input from the calling subscriber in response to the recording message, and then replays the message when the subscriber having the function ends. To be sent out.

Next, a method of transmitting a message to a subscriber during a call in an electronic switch system according to an embodiment of the present invention will be described in detail with reference to the flowcharts shown in FIGS. 2 (a) and 2 (b). .

When the subscriber A hooks off the handset to form a loop and then inputs a calling number, the digit according to the called number is the ASP (27). CDL (31) The NTP 38 is transmitted to the NTP 38 through the HIPCU 33, and the NTP 38 translates the called number based on the digital signal, and then accesses the subscriber corresponding to the called number through the HIPCU 33. An ASP 27 is requested to connect with the called subscriber, for example, B subscriber.

Accordingly, the called party ASP 27 applies a predetermined driving signal to the RG 22 connected to the ASI 21 to which the subscriber B is connected so that a ringing tone is generated at the RG 22. The ringing tone generated at) is transmitted to subscriber B through ASI 21.

At this time, the destination ASP 27 is a ring back tone generated in the LSI (not shown) is the TSL (26) CDL (31) TSL (6) To the subscriber A via the ASI 1 (step 50).

On the other hand, when subscriber B responds to the ringing tone output from the handset, the telephone hook-offs the handset to form a loop, and a call path between subscriber A and subscriber B is established so that subscribers A and B exchange voice signals. (Step 52).

On the other hand, in step 52, while the subscribers A and B are conducting a call, subscriber C hooks off and inputs the telephone number of subscriber B so that the called number is translated from the NTP 38 and subscriber B is subscribed. If the connected ASP 27 is requested to the connected ASP subscriber (step 54), the ASP 27 determines whether the subscriber B is a function holder registered to the function assumed in the present invention ( Step 56).

At this time, if the subscriber B is not registered as a function-bearing subscriber (NO in step 56), the ASP 27 generates the talk sound generated by the LSI in the TSL 26. CDL (31) TSL (6) The ASI 3 transmits to the subscriber C (step 58).

On the contrary, if it is determined in the ASP 27 that the subscriber B is registered as a function-bearing subscriber (YES in step 56), the ASP 27 receives the CDL 31. HIPCU (33) An IPC message is sent to the GSP 35 via an INP 34 so that the GSI 36 is driven by the GSP 35 (step 60).

As the GSI 36 is driven, the recording announcement broadcast generated from the GSI 36, for example, the subscriber is busy, records a beeping sound and presses an asterisk after the recording is finished. Is the SSW 32 CDL (31) TSL (6) The ASI 3 is sent to the subscriber C (step 62).

If the C subscriber who listens to the recording announcement output from the handset inputs a specific voice signal after the beeping sound in response to the recording announcement, the corresponding message is sent to the ASI (3). TSL (6) CDL (31) When the digit signal corresponding to an asterisk (*) is input from the C subscriber through recording in the GSI 36 through the SSW 32, the recording in the GSI 36 is terminated (step 64).

Then, the ASP 27 monitors the situation of subscribers A and B (step 66), and then monitors whether subscriber B is hooked on (step 68).

Accordingly, when the subscriber B in the ASP 27 hooks on the handset and the loop is closed (YES in step 68), the ASP 27 applies a predetermined control signal to the ASIP 25 to the B. The subscriber makes a ring tone from the RG 22 installed corresponding to the connected ASI 21, and then the ring tone is transmitted to the subscriber B through the ASI 21 so that the subscriber B is called (step 70). ).

When the subscriber B responds to the call and hooks off the handset to form a loop, the ASP 27 returns to the TSL 26. CDL (31) HIPCU (33) An IPC message is sent to the GSP 35 via an INP 34 so that the GSI 36 is driven by the GSP 35 (step 74).

Here, as the GSI 36 is driven, a message recorded by the subscriber C generated from the GSI 36 is reproduced to the SSW 32. CDL (31) TSL (26) The subscriber A's message is sent to the subscriber A via the ASI 21, so that the subscriber A can listen to the message from the subscriber C who has called during the call with the subscriber B (step 76).

As described above, according to the message transmission service method to a subscriber during a call in an electronic switching system according to an embodiment of the present invention, when a call is received from any originating subscriber to a functioning subscriber in a call, the calling subscriber is sent to the calling subscriber. Transmitting a recording announcement to temporarily store a message corresponding to the voice signal input from the calling party, and when the function-holding subscriber ends the call, calls the function-holding subscriber to hold the stored message from the calling party. By sending to the subscriber, the function-bearing subscriber can easily check the message from the calling subscriber who has called the function-bearing subscriber during the call, thereby providing a more convenient service to the subscriber.
