Receipt handling method of relay call guide at domestic electronic exchange

The present invention relates to a method for handling incoming calls in a relay call home guide in a local telephone switchboard, and more particularly, to a method for handling incoming calls in a relay call home guide in a public telephone switchboard that enables other subscribers to use the services of their own guides. It is about.

As is well known, an electronic switch is designed as a means for providing an optimized call service for call setup and call request generated in the subscriber terminal while a plurality of subscriber terminals are connected and applied to practical use as a national exchange means. It is a state.

According to such an electronic switchboard, the subscriber station is connected to the call path network via a subscriber line, for example, including a semiconductor switch, and the connection with other switching stations is made through a trunk. In addition, the electronic switchboard includes a device (Scanner) that detects all events occurring in subscriber lines and trunks and notifies the control unit, for example, an on-off hook of a handset, a telephone number to dial, and an incoming signal from another station. The state of the relay line (collinear line or fire) is detected.

In addition, the electronic switching system also includes signaling equipment for handling the signals to be transmitted on the line, which may be, for example, under the control of a control unit, for example, a dial tone, a call tone, a call tone, a call signal current. For example, a signal transmitted to an exchange of another station is generated.

Here, according to such an electronic switchboard, if the format of the other exchange which accommodates the other subscriber station which is the target of the call setup request originating from the subscriber of the own country is different from that of the own exchange, the direct call with the subscriber terminal of the other exchange is performed. Setting processing becomes impossible.

Therefore, in view of such a situation, for example, it is assumed that a billing process that requires a separate billing process for a subscriber station of its own country or a call connection to an exchange of another station adopting a different exchange method is required. The so-called 'OPS (Operator Position System)' connection is considered in the electronic exchange, and the guide is connected to the other party connected to the other exchange in a different exchange system in response to a call setup request generated at the subscriber station of the local exchange. It performs the action of performing a call connection to.

However, as described above, since the reception desk housed in the local electronic switchgear is configured to provide the reception desk service only to the subscribers of the home country, the subscribers of the other countries who are subscribed to the other country's exchange do not use the reception desk service provided from the local tour desk. There was a problem that it could not be used.

Accordingly, the present invention has been created in view of the above circumstances, and has added a relay call forwarding function to the information desk connected to the ISDN subscriber registration unit so that other subscribers can use the information service provided from the information desk.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a block configuration of an internal incoming call processing apparatus for a trunk call guide in a local telephone exchange system according to an embodiment of the present invention.

In Fig. 1, reference numeral 1 denotes an exchange of other stations to which a general subscriber is connected, and 2 denotes a slave station of which a local station guide 8 is connected.

As shown in Fig. 1, the local exchange 2 has a relay line signal section 3, a number translation section 4, a relay call processing section 5, an OPS control section 6, and an ISDN matching stage 7; It consists of.

Here, the relay line signal unit 3 receives various messages transmitted from the other station switch 1, for example, a relay line occupied signal, a digit, a source information signal, and the like, and processes the relay call with the other station switch 1 for processing. Various messages to be transmitted are transmitted, for example, a source information request signal, a frequency of 500 [Hz], and various ring tones (middle sounds, ring back tones).

In addition, the relay call processor 5 applies the digit received from the relay line signal unit 3 to the number translation unit 4 to be described later so that the received number is translated, and the outgoing information is transmitted to the relay line signal unit 3. It transmits a message according to a request signal, an MFS / R (Multi-Frequency Sender / Receiver) occupancy request signal, a transmission information acknowledgment signal, and a control signal for generating tones. Further, the relay call processor 5 determines the busy / idle state of the guide 8 so that the guide 8 in the idle state is called.

Further, the number translation unit 4 translates the received number based on the digits applied from the relay call processing unit 5, and transmits the information of the calling subscriber based on the originating information applied from the relay call processing unit 5. It analyzes and requests the call of the guide 8 according to the reception number translated by the OPS control unit 6 which will be described later.

Then, the OPS control section 6 and the ISDN protocol of the guide 8 connected to the ISDN matching stage 7 to be described later on the basis of the message from the relay call processing section 5 or the number translation section 4 and In addition to controlling the call processing, the state of the guide 8 is monitored and reported to the relay call processing unit 5.

The ISDN matching stage 7 also performs an interfacing function for the general ISDN subscriber or guide 8 to which it is connected.

In addition, in FIG. 1, reference numeral 8 denotes at least one or a plurality of local exchanges, so as to respond to a call establishment request generated by the originating party, for example, a guide for processing a call establishment with a subscriber station accommodated in a foreign exchange. It is.

Hereinafter, with reference to the flowchart shown in Figures 2a, 2b, 2c will be described in detail the method of handling the relay call mark guide guide in the local electronic switchboard according to an embodiment of the present invention.

First, when the relay line occupancy signal transmitted from the other station switch 1 is received by the relay line signal unit 3, the relay line signal unit 3 reports the relay line occupation to the relay call processor 5 (step 10). The relay call processor 5 receiving the relay line occupancy request checks whether the corresponding signal type is the MFC (Multi Frequency Code) method or the DEC (Decadic) method, and then sends a message regarding the signaling method to the relay line signal part 3. send.

Subsequently, the relay line signal unit 3 receives the digits transmitted from the other station switch 1 based on the corresponding message (step 12), and reports the received digits to the relay call processor 5.

The relay call processing unit 5, which has received the corresponding received digit, requests the number translation by authorizing the received digit to the number translation unit 4 (step 14), and receives the number translation request (4). After translating the received number corresponding to the digit, it is determined whether the translated received number is a receiving number for a general subscriber or a receiving number for a guide (step 16).

As a result of the determination, if the corresponding reception number is the reception number for the general subscriber (NO in step 16), the number translation unit 4 requests the connection of the general subscriber and the calling subscriber connected to the foreign exchange 1 and the general subscriber. A call path between subscribers is established to allow normal telephone call (step 18).

However, if the corresponding reception number is the reception number for the guide in step 16 (YES in step 16), the number translation unit 4 requests the call of the guide 8 to the OPS control unit 16 (step 20).

After receiving the call request, the OPS control unit 6 checks the state of the guide 8 and reports the information of the called subscriber (general subscriber, guide) to the relay call processor 5 (step 22). .

The relay call processor 5, which has reported the state of the guide 8, analyzes the information of the called party and determines that the guide 8 is in an idle state when the called subscriber is a guide. Next (step 24), if it is determined that the guide 8 is not in an idle state, that is, in a busy state (NO in step 24), the relay call processing unit 5 determines that the guide 8 is in an idle state. After that, it is treated in the waiting state to be able to call.

However, on the contrary, if the guide 8 is judged to be in the idle state in step 24 (YES in step 24), the relay call processing unit 5 checks the relay line signaling method and determines whether the relay line signaling method is the DEC method. If the relay line signaling method is DEC (YES in step 28), the relay call processing unit 5 monitors MFS / R (Multi-Frequency Sender / Receiver) (step 30). It is determined whether there is an idle MFS / R (step 32).

If there is no MFS / R idle in step 32 (NO in step 32), the relay call processing section 5 sends a call sound generation request signal to the relay line signal section 3, and the call sound generation signal. The relay line signal unit 3 receiving the call transmits a busy tone to the foreign exchange 1 so that the calling subscriber connected to the foreign exchange 1 receives a busy tone and then disconnects the call. (Step 34).

On the contrary, when it is determined that there is an idle MFS / R in step 32 (YES in step 32), the relay call processing unit 5 requests the relay line signal unit 3 to send outgoing information request signal (step 36), the relay line signal section 3 requests the occupation of the MFS / R (step 38).

Accordingly, the relay line signal unit 3 transmits the corresponding outgoing information request signal to the other station exchange 1 in response to the outgoing request of the corresponding outgoing information request signal (step 40), and then sends the signal to the other station exchange 1 (500). In addition to transmitting a frequency of [Hz], the MFS / R is occupied in response to a request for occupying the corresponding MFS / R from the relay call processor 5 (step 42).

On the other hand, if it is determined in step 28 that the relay line signal method is not the DEC method, that is, the MFC method, the relay call processor 5 proceeds to step 36 to perform the above-described process.

On the other hand, the relay line signal unit (3) when the transmission / reception of the outgoing information failed due to the abnormal state of the corresponding line, the other station switch 1 during the transmission / reception of the corresponding outgoing information request signal outgoing information transmission / The reception failure signal is reported to the relay call processor 5 (step 44).

The relay call processing unit 5 which has reported the transmission / reception status of the transmission information from the relay call processing unit 5 determines whether the transmission information transmission / reception was successful (step 44), and the relay line signal unit 3 When the outgoing information signal failure signal is transmitted (NO in step 44), the relay call processing unit 5 determines whether the number of times that the outgoing information transmission / reception fails is more than the preset retry setting number (step 46).

As a result of the determination, if the number of times that the transmission / reception of the transmission information has failed is less than or equal to the preset retry setting number (NO in step 46), the relay call processing unit 5 proceeds to the step 36 to repeatedly perform the above-described series of operations. On the other hand, if the number of times that the corresponding transmission information transmission / reception fails more than a preset retry setting number (YES in step 46), the relay call processing unit 5 sends a call sound generation request signal to the relay line signal unit 3 The trunk line signal section 3 receiving the call tone generation signal transmits a busy tone to the other station switch 1 so that the calling subscriber connected to the other station switch 1 receives a call tone. The arc is then cut (step 48).

On the other hand, if the outgoing information transmission / reception success signal from the relay line signal part 3 is reported to the relay call processing part 5 (YES in step 44), the relay call processing part 5 is the relay line signal part 3. After storing the information of the calling subscriber (eg, calling number, calling grade) among the messages received and authorized in step S, the relay line signal part 3 requests the transmission of the calling information acknowledgment signal (step 50).

The relay line signal unit 3 having received the corresponding transmission information reception confirmation signal transmits the transmission information reception confirmation signal to the other station switch 1 and reports the completion of the transmission information signal to the relay call processing unit 5 (step 52). ).

The relay call processor 5, which has reported the completion of the transmission information signal, cuts the MFS / R occupied in step 42 (step 54), and reports the outgoing subscriber information to the number translation unit 4, The number translation unit 4 requests the analysis of the rating of the calling subscriber.

Accordingly, when the number translation unit 4 analyzes the grade of the corresponding calling subscriber and then reports the analysis result to the relay call processing unit 5, the relay call processing unit 5 in the number translation unit 4 On the basis of the analysis result, it is determined whether the calling party is a valid calling party that is eligible to call the information desk (step 58), and if it is determined that the calling party is not a valid calling party (step 58). NO at 58) The trunk line signal section 3, which transmits a call sound generation request signal to the trunk line signal section 3 and receives the talk line sound generation signal, sends a busy tone to the other station switch 1. The call is disconnected after the calling party connected to the other station switch 1 receives a busy tone (step 60).

On the contrary, if the calling party is determined to be a valid calling party by the relay call processor 5 (YES in step 58), the relay call processor 5 generates ring back / tone by the relay line signal part 3. The relay line signal section 3, which has transmitted a request signal and received the ring back tone generation signal, transmits a ring back tone to the other station switch 1 so as to transmit the ring back tone. Call back subscriber may receive a ring back tone (step 62).

At the same time, the relay call processor 5 reports outgoing subscriber information (e.g., calling number and calling grade) to the OPS control unit 6 (step 64), and the OPS control unit 6 receiving the outgoing subscriber information. Stores the corresponding outgoing subscriber information and then sends a call notification to the information desk 8 connected via the ISDN matching unit 7 (step 66).

Subsequently, the OPS controller 6 reports the response of the guide 8 to the relay call processor 5 (step 68), and the relay call processor 5 receives the response report of the guide 8. ) Transmits the ring back tone cutting request signal to the relay line signal section 3 so that the ring back tone transmitted from the relay line signal section 3 to the other station switch 1 is cut (step 70). ).

Then, the relay line signal unit 3 terminates a series of operation processes after connecting a speech path between the foreign station switch 1 and the corresponding guide 8 (step 72).

On the other hand, when the charging method is free, the relay line signal section 3 does not send a response signal to the other station switch 1, but when the charging method is paid, the response signal is sent.

According to the method of receiving relay call guide guide reception in a local telephone exchange according to an embodiment of the present invention, the subscriber of another station connected to the other station by adding the relay call reception function to the guide connected to the ISDN subscriber registration unit By accessing the guide and using the guide service provided by the guide, it is possible not only to improve the service efficiency of the guide, but also to efficiently operate the guide.
