Description

How to handle relay call to other country members

The present invention relates to a relay call processing method for subscribers of other countries, more specifically, the domestic guides connected to the domestic guides in response to the call transfer service request of the subscribers of the other country. The present invention relates to a method of handling relay calls for other subscribers of the National Guard who is able to handle the calls and handle the charges generated during the relay call.

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 (collinearity 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 domestic exchange, the direct call establishment with the subscriber terminal of the other exchange is performed. Processing becomes impossible.

Therefore, in view of such a situation, for example, a call connection to an exchange of another country employing a different exchange method or a separate billing process for a subscriber station of its own country is required. OPS (Operator Position System) 'connection is considered, and the guide in response to the call setup request generated at the subscriber station of the local exchange exchanges the call connection to the other subscriber connected to the other exchange of different exchange method. The action to perform is performed.

On the other hand, the information desk has a problem that the target of the transfer service is extremely limited because the transfer service only performs the transfer service for the subscribers subscribed to the home exchange.

In addition, in order to solve this problem, there is a need for an exchange system capable of performing the call transfer service to other countries, and in order to implement such a function, a billing problem that may occur by performing the function, namely For example, when another country calls its guide or general guide and transfers it to its subscribers, the application is charged to the calling subscriber. However, when the call is transferred to another subscriber, the billing rate application standard is applied. As such, it must be accompanied by reasonable billing.

Accordingly, the present invention has been made in view of the above-described circumstances, and the local guides connected to the own guides relay the call between the subscribers of the other country and the subscribers of the other countries in response to the call transfer service request of the subscribers of the other country. Its purpose is to provide a method of handling relay calls for other subscribers of the National Guard who is able to handle the charges incurred in relay calls.

According to one embodiment of the present invention for realizing the above object, in a local exchange that is located between an originating exchange and a terminating exchange, and performs a relay call processing function between other stations, the originating subscriber of the other station transfers the call to its own information desk. The call is disconnected and the calling party is called by a foreign subscriber who has been transferred by the subscriber, and when the foreign subscriber who responds to the call accepts the transfer request, the foreign subscriber is accepted. Waiting for a temporary step, reporting the state of calling the foreign subscriber by calling the foreign subscriber, connecting the foreign subscriber to the foreign subscriber and connecting the foreign subscriber to the foreign subscriber; Initiating a call between subscribers; and sending / receiving by the other subscriber or the other subscriber A hook-relay call processing method for a single subscriber stations marks guide consisting of steps that the call is terminated if one is provided.

In the present invention, preferably, the call between the originating call processing unit and the originating call processing unit set as the charge designated point of the first originating call processing unit and the second originating call processing unit after the call between the subscriber originating from the other country and the foreign destination is initiated. Save the billing information in the message, and after the call is terminated, the originating call processing part set as the billing designation point of the first outgoing call processing part and the second outgoing call processing part is based on the pre-stored billing information. The method further includes generating a new billing information by calculating the time / call progress time and the like and reporting the billing information to the billing controller and the guide stand controller.

Preferably, in the present invention, the billing information stored in the first and second outgoing call processing units may include a PPM code, a subscriber number of a foreign subscriber, a subscriber number of a foreign subscriber, a guide ID number, a subscriber number of a foreign subscriber, and a call. It is characterized in that the start time, the charge designation point is set by only one side of the first outgoing call processing unit and the second outgoing call processing unit by the guide station control unit.

Preferably, the charging information applied to the charging control unit is stored in the storage means, the charging information reported to the guide control unit is output through the monitor screen of the guide and at the same time the storage means equipped on the guide Are stored in.

According to the present invention made up of the above steps, when the caller of the other country requests the call transfer service according to the guide of the home country, the relay call processing function by connecting the call between the caller of the other country and the destination subscribers who are the targets of the call transfer service. In addition, the charge generated in the relay call processing is processed by the local exchanger in which the own guide is accommodated.

In this figure, reference numeral 1 denotes a caller for an incoming or outgoing call for the calling party 11 connected to another calling party 11. 3 is a called station exchanger that performs an exchange function, and 3 denotes a called station exchanger that is connected to an incoming subscriber 12 of another station and performs a telephone exchange function for an incoming or outgoing call to the called subscriber 12.

Further, reference numeral 2 denotes a local exchange which is provided between the originating exchange 1 and the terminating exchange 3 to process a relay call between the originating exchange 1 and the terminating exchange 3, In response to the request of the calling party 11 of the calling party exchange 1, the local switching machine 2 calls the called party 12 of the called country exchange 3, so that the calling party 11 and the called party ( 12 is connected to a guide 8 that performs the overall function of the call transfer service according to the relay call processing.

Meanwhile, the local exchange 2 processes the relay call between the originating exchange 1 and the destination exchange 3 as well as processing billing information generated during the heavy call processing, as shown in FIG. For this purpose, the call forwarding call processing unit 4 includes a first call forwarding call processing unit 4, a first call forwarding call processing unit 5, a guide stand control unit 6, a charging control unit 7, and a second call forwarding call processing unit 9.

Here, the incoming call processor 4 is a block responsible for relay line signal control and call processing for a call received from the originating station switch 1 to the local station switch 2, and the relay call processor 4 is a block. On the basis of a predetermined message applied from the guide stand control section 6, various types of tones are generated and transmitted to the calling station switch 1 side.

In addition, the first originating call processor 5 is responsible for relay line signal control and call processing when performing a call transfer service to a destination subscriber 11 of another station, and the charging point by the guide controller 6. A block that performs the function of processing the billing information for the call on the basis of the designation, the second outgoing relay call processing unit (9) to the originating subscriber 11 of the originating exchange (1) applying for call transfer service In the case of performing the call transfer service, it performs the function of controlling the relay line signal and handling the call, and also processes the charging information on the call based on the charge point designation by the guide controller 6. Block.

In addition, the guide control unit 6 is a block that performs a function of controlling the ISDN protocol and call processing of the guide 8 connected to the ISDN (2B + D) channel, 7 is the first originating relay call. The billing information (ie, call start time / billing rate application criteria / calling number / calling number / guide number), etc., which is authorized from the processing unit 5 and the second outgoing call processing unit 9, may be used as a diskette unit (DKU) or the like. This block is stored in the magnetic tape MT.

Subsequently, with reference to the flowchart shown in Figures 2a, 2b, 2c it will be described in detail the operation of the relay call processing method for the subscriber of the national guide according to an embodiment of the present invention having the above-described configuration in detail do.

First, the calling party 11 of the calling party exchange 1 calls the guide 8 connected to the local switching station 2 to make a call (step 20), and the calling party 11 calls the guide ( 9) apply for a call transfer service for a call connection to any called party 12 subscribed to the called party exchange 2 (step 21), and then the calling party 11 hooks on the transmitter / receiver. (HOOK-ON) When the call from the calling party 11 is disconnected and the calling party call cancel signal transmitted from the calling party exchange 1 is received by the incoming call processing part 4, the incoming call processing part ( 4) the originating party call cutting report is made to the guide control unit 6 (step 22).

On the other hand, at this time, when the call is disconnected from the guide 8, the guide control unit 6 reports the guide call to the incoming call processor 4, and the incoming call processor 4 reports the originating station exchanger. The call between the guide 8 and the calling party 11 is terminated by transmitting a guide grand release signal to (1).

Then, the guide control unit 6 transfers the subscriber number of the call transfer request destination subscriber that is requested by the calling subscriber 11 to the first calling relay call processor 5, and the first calling relay. The call processing unit 5 performs a number translation on the corresponding subscriber number and transmits a call signal for the called party to the called country exchanger 3 in which the called party receiving party (hereinafter referred to as the called party 12) is accommodated. The called party exchange 3 calls the called party 12 by causing a ring tone to be outputted to the called party 12 accommodated in the called party exchange 2 based on the call signal (step 23).

Accordingly, when the called party 12 receives the incoming subscriber response signal from the called country switch 2 to the first originating call processor 5 as the receiver hooks off the receiver. The first originating call processing unit 5 transmits the incoming subscriber response report message to the information base control unit 6 (step 24).

Accordingly, the call between the guide 8 and the called party 12 is carried out through the call path set between the guide 8 and the called party 12 (step 25). 8) the operator operating the call to the receiving party 12 to inform the status that the transfer service is applied to ask whether to accept the transfer service, in the process the called party 12 transfers the call If the service is accepted, the call forwarding hook-fresh signal is transmitted to the first outbound call processor 5 so that the call waiting tone is transmitted from the first outbound call processor 5 to the called party 12. The transfer wait tone is output (step 26).

Then, the guide control unit 6 transmits the subscriber number of the call transfer application originating subscriber (hereinafter referred to as the calling subscriber 11) to the second outgoing call processing unit (9), the second outgoing call processing unit (9) translates the corresponding subscriber number and transmits the calling signal to the calling station switch 1, in which the calling party 11 corresponding to the subscriber number is accommodated, and the calling station switch 1 is based on the calling signal. The calling party 11 is called by causing a ringing tone to be outputted to the calling party 11 accommodated in the exchange 1 (step 27).

In response to the call, the calling party 11 responds by hooking-off the sender / receiver of the calling party 11 so that the call transfer request originating party response signal sent from the calling party exchange 1 is transmitted to the second calling relay. When received by the call processing unit 9, the second outgoing relay call processing unit 9 reports the call transfer request originator response to the guide controller 6 (step 28).

As a result, a call path between the guide 8 and the calling party 11 is set so that the call between the guide 8 and the calling party 11 is performed, and the operator of the guide 8 Notifying the calling subscriber 11 that the call with another destination subscriber has been connected, the guide station control unit 6 reports the call transfer service connection to the first and second calling relay call processing units 5 and 9 at the same time. The second outgoing call processing unit (9) receiving the call transfer service connection report connects a channel to the channel of the first outgoing call processing unit (5), and the first outgoing call processing unit (5). ) Disconnects the call waiting tone that is being transmitted while connecting a channel to the channel of the second outgoing call processor 9.

In this state, the second originating call processor 9 checks the presence or absence of the charge designation point in the message reported from the information base control unit 6 and determines whether it is set as the charge designation point (step 31). If it is determined that the second outgoing call processing unit 9 is set as the charge designation point (YES in step 31), the second transmission relay call processing unit 9 stores the charge transfer unit after the call cutting and then stores the charge transfer unit in the message received from the guide control unit 6; 1 Stores the processor number and channel number of the originating relay call processor 5 newly. In addition, it stores all the information necessary for generating billing information such as PPM Code, subscriber's subscriber number of calling service, calling subscriber's name, subscriber's subscriber number, recipient's name, guide ID number, call connection start time, etc. In addition, while storing the processor number of the guide control unit that is connected to the guide to report the charge after the call cutting (step 32), if the second outgoing relay call processor (9) is not set as the charging designated point (step 32). NO at 31) Only the processor number and the channel number of the first originating call processor 5 are newly stored among the messages notified by the guide controller 6 (step 33).

Subsequently, the first originating call processing unit 5 checks whether or not the charge designation point is set in the message reported from the information desk control unit 6 and determines whether it is set as the charge designation point (step 34). If the second outgoing call processing unit 9 is set as a billing designation point (YES in step 31), the first outgoing message is received from the message transmitted from the information base controller 6 after storing the billing forwarding part after the call disconnection. The processor number and the channel number of the relay call processor 5 are newly stored. And, create new billing information such as PPM Code, caller's subscriber's number, caller's subscriber's name, caller's subscriber's number, caller's subscriber's name, information desk ID number, call connection start time, etc. In addition to storing all the information required for the storage and the processor number of the guide control unit that is connected to the guide to report the charge after the call cutting (step 35), the first call relay processing unit 5 to the charge designated point If not set (NO in step 34), only the processor number and the channel number of the second outgoing call processing unit 5 are newly stored among the messages notified by the guide controller 6 (step 36).

Through the above-described process, a call path is connected between the calling party 11 and the called party 12 to make a call between the calling party 11 and the called party 12.

On the other hand, during the call between the calling party 11 and the called party 12 through the above process, the calling party 11 first cuts out the call and is sent from the calling party exchange 1 When the release signal is received by the second outgoing call processing unit 9 (step 41), the second outgoing call processing unit 9 disconnects the channel and the relay line that is being connected and then the second outgoing call processing unit 9 ) Is set as the charging designated point (step 42), and if the second outgoing call processing unit 9 is set as the charging designated point (YES in step 42), the second outgoing relay call The billing information stored in the processing unit 9 and the call start time / call end time / call progress time, etc. are calculated to generate new billing information and report the generated billing information to the billing control unit 7 and at the same time the guide. Report to control unit 6 It is (step 43).

In this state, the charging control unit 7 stores the charging information reported from the second originating call processing unit 9 in a storage means, for example, a diskette unit (DKU) or a magnetic tape (MT), and the guide stand control unit ( 6) the charging information reported from the second outgoing call processing unit 9 is output through the monitor screen of the guide 8 and stored in the storage means provided in the guide 8; .

After performing the above process, the second outgoing call processing unit 9 reports the call transfer request originator call cutting to the first outgoing call processing unit 5 (step 64) and sends the corresponding call transfer request. The first outgoing call processing unit 5 that has received the subscriber call disconnection report determines whether the first outgoing call processing unit 5 is set as a charging designated point (step 45).

As a result of the determination, if the first outgoing call processing unit 5 is set as a charge designating point (YES in step 45), the first outgoing call processing unit 5 is based on pre-stored billing information and counted talk time. After calculating the call charges, the call charges and the billing information are reported to the charge control unit 7 and to the information counter control unit 6 (step 46). While transmitting the cut signal to terminate the call route established between the calling party 11 and the called party 12 (step 47), in step 45, the first calling relay processing unit 5 goes to the designated billing point. If not set (NO in step 45), the flow advances to step 47 to terminate the call route established between the calling party 11 and the called party 12.

On the other hand, as described above, if the call is disconnected by the called party 12 without cutting the call by the calling party 11, the first calling relay processing unit 5 is the first calling relay call processing unit ( 5) is determined as the billing designation point, and if the first outgoing call processing unit 5 is set as the billing designation point, the billing information previously stored in the first outgoing call processing unit 5 and Calculate the call start time / call end time / call progress time and the like to generate new billing information and report the generated billing information to the billing controller 7 and at the same time to the guide counter controller 6 The call forwarding call destination cut-off report is reported to the second call relay processing unit (9).

Subsequently, the second outgoing call processing unit 9 determines whether the billing designation point is set, and if the second outgoing call processing unit 9 is set as the billing designation point, previously stored billing information and call start time / Calculate call termination time / call progress time and the like to generate new billing information, report the generated billing information to the billing controller 7 and at the same time report to the guide counter controller 6 and then to the calling station switch 1 Transmits the call transfer request destination subscriber call termination signal to terminate the call path established between the calling party 11 and the called party 12.

On the other hand, in the above-described series of processes, the guide stand control unit 6 sets the charge designation point only on one side of the first originating call processing unit 5 and the second originating call processing unit 6, and thus the origination of one side. When the charge designation point is set in the relay call processing unit, the charge designation point is not set in the other outgoing call processing unit.

As described above, according to the relay call processing method for the subscriber of the national guide according to the embodiment of the present invention, the domestic guide may not only perform the call transfer service between the subscribers of the other country and the subscribers of the other country. By applying the appropriate billing rate application criteria for the call for which the conversion service is performed, it is possible to reasonably calculate the call charge for the call, thereby expanding the coverage of the call transfer service.

In addition, the information desk can immediately inform the billing information when the billing information inquiry from the calling subscriber after the call.
