Description

How to transfer services to subscribers of other countries

The present invention relates to a call transfer service method for a foreign member of the National Guidance Center, and more particularly, when a subscriber from another country requests a transfer to a foreign subscriber in accordance with their own country guide, and then the call is terminated by the subscriber from another country. If the caller of another country and the caller of another country answer the call, the caller of the foreign country is called while waiting for the caller of the foreign country. The present invention relates to a call forwarding service method for a subscriber of another country, which can be connected to a call of a called party.

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.

However, in order to solve this problem, an exchange system capable of performing the call transfer service to other countries is required, 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 when a caller from another country requests a call to another caller according to his or her guide, the caller terminates the call when the caller terminates the call. When a foreign subscriber subscribes to the call, the foreign call subscriber is called while the foreign subscriber subscribes to the call. When the foreign call subscriber answers the call, the foreign subscriber connects the call with the foreign subscriber. Its purpose is to provide a method of transfer services to other members of the National Guard that is available.

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. Requesting and then cutting the call; and calling a foreign destination subscriber who has been transferred by the subscriber of the foreign country; if the foreign subscriber who responded to the call accepts the call transfer request; Waiting the subscriber temporarily, calling the foreign subscriber to set up a call route between the called subscribers when the foreign subscriber subscribes to the call; and the foreign subscriber or the foreign subscriber subscribes to the foreign subscriber. A call to another country's subscriber, which consists of a step in which the call is terminated when the receiver is hooked on. This scan method is provided.

Preferably, when any one of the first originating call processing unit and the second originating call processing unit is set as a charge designating point in a state of calling the other party originating subscriber, the accounting information is stored, and the state from which the other party originating subscriber responds. If either one of the first outgoing call processing unit and the second outgoing call processing unit is set as the billing designation point, the call time is indicated, and the first outgoing call processing unit and the second outgoing call in the state where the call is terminated. If any one of the processing unit is set to the charge designation point, and further comprising the step of calculating the call charges based on the charge information and the call time and then approving the call charges and the charge information to the charge control unit and the guide control unit; It is characterized by.

Preferably, the charge designation point is set by only one side of the first call signal relay call processing unit and the second call relay call processing unit by a guide control unit.

In addition, preferably, the call charge and the charge information applied to the charge control unit are stored in a storage means.

Preferably, the call charge and the billing information applied to the guide stand control unit are output through a monitor screen of the guide stand and are stored in a storage unit provided at the guide stand.

According to the present invention made up of the above steps, the guide can not only perform the transfer service between the subscribers from the other country and the subscribers from other countries, but also by applying the appropriate billing rate application criteria for the call on which the transfer service is performed. By reasonably estimating the charge for the call, the guide can provide the transfer service to the other countries.

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, as shown in FIG. 1, the local exchange 2 processes the relay call between the originating exchange 1 and the destination exchange 3 and processes the billing information generated during the relay call. 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.

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 incoming call processor 4 Generates various beeps based on the predetermined message applied from the guide stand control unit 6 and transmits them 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 for a diskette unit (DKU) or This block is stored in the magnetic tape MT.

Next, with reference to the flowchart shown in Figures 2a, 2b, 2c attached will be described in detail the operation of the call transfer service method for the subscriber of the national guide according to an embodiment of the present invention with 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 received by the calling party call canceling signal from the calling party call processor 1, the incoming call processing part 4 receives the incoming call processing part 4 C) reports the calling party call cutting to the guide controller 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 transmits the subscriber number of the call forwarding application destination subscriber to the first outgoing call processor 5, the first outgoing call processor 5 for the corresponding subscriber number By performing a number translation, a call signal for the called party is transmitted to a called country exchanger 3 in which the called party's called party (hereinafter referred to as the called party 12) is accommodated. The calling party 12 is called by causing the ringing tone to be outputted to the called party 12 accommodated in the called country exchange 2 based on the calling party 12 (step 23).

Accordingly, when the called subscriber 12 receives the incoming subscriber response signal from the called station 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 this state, the second outgoing call processing unit 9 receives a ring back tone signal output from the originating station switch 1, while the ring back tone signal is received while the ring back tone signal is received. 6) a call transfer service connection report is reported to the first call relay call processor 5 and the second call relay call processor 9 (step 28); the second call received the call transfer service connection report; The relay call processor 9 newly stores the processor number and the channel number of the first originating call processor 5 in the message notified by the guide controller 6, and the first originating call processor 5 Stores the processor number and channel number of the second outgoing relay call processor 9 in a message notified by the guide controller 6.

Subsequently, the second originating call processing unit 9 determines whether the charge setting point is set by the guide stand control unit 6 (step 29), and the guide stand control unit 6 determines the second originating call. If it is determined that the processing unit 9 is set as the charging designation point (YES in step 29), the second call relay processing unit 9 stores the charging information notified from the guide controller 6, while If it is not determined that the second outgoing call processing unit 9 is set as the billing designation point (NO in step 29), the first outgoing call processing unit 5 is transferred to the billing designation point by the guide stand control unit 6. It is determined whether it is set (step 31).

As a result of the determination, when it is determined that the guide station control unit 6 sets the first originating call processing unit 5 as the charge designating point (YES in step 31), the first originating call processing unit 5 After storing the billing information notified from the guide station control section 6, the call waiting tone sent to the destination station exchange 3 is cut, and the ring back tone signal is transmitted to the destination station exchange 3. The ring back tone is output to the waiting recipient (step 33).

In this state, as the calling party 11 responds to the hook-off, the call transfer request output from the calling station switch 1 by the second calling relay call processor 9 is performed. When the calling party response signal is received (step 34), the second calling relay processing unit 9 determines whether it is set as a charging designated point (step 35), and as a result, the second calling relay calling processor 9 is determined. If it is set as the charge designation point (YES in step 35), the second outgoing call processing unit 9 starts counting the talk time (step 36) and then sends a call transfer request to the first outgoing call processing unit (5). While the subscriber response report is made (step 37), if the second outgoing call processing unit 9 is not set as the charge designation point (NO at step 35), the second outgoing call processing unit ( 9) proceed to step 37 the first Report call transfer request originator response to outgoing relay call processor (5).

Subsequently, it is determined whether the first outgoing call processing unit 5 is set as the charging designation point (step 38). If the first outgoing call processing unit 5 is set as the charging designation point (step 38), YES at 38) the first outgoing call processing unit 5 starts counting talk time (step 39) and then stores the processor in the first outgoing call processing unit 5 and the second outgoing call processing unit 9. On the basis of the number and the channel number, the call route is established by signally connecting the first outgoing call processing unit 5 and the second outgoing call processing unit 9 (step 40). If the first originating call processing unit 5 is not set as the charging designation point (NO in step 38), the flow advances to step 40 above.

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 determines whether the second outgoing call processing unit 9 is set as a charging designated point. If the second outgoing call processing unit 9 is set as the charge designation point (YES in step 42), and the counting information and counting information stored in the second outgoing call processing unit 9 are determined. After calculating the call charges based on the talk time, the call charges and the charge information are reported to the charge controller 7 and to the guide controller 6 (step 43).

In this state, the charging control unit 7 stores the call charge and billing information reported from the second outgoing call processing unit 9 in a storage unit, for example, a diskette unit (DKU) or a magnetic tape (MT), and guides the information. The grand controller 6 is configured to output the call charge and billing information reported from the second originating call processor 9 through the monitor screen of the guide 8 and at the same time. To be stored in the storage means.

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 billing designation point has been set by the first outgoing call processing unit 5 (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 charging information and counting information stored in the first outgoing call processing unit 5 are determined. The call charge is calculated based on the talk time, and the call charge and the billing information are reported to the charge controller 7 and to the guide controller 6, and then the second call relay processor 9 Report the call forwarding request cutoff.

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, the pre-stored billing information and the talk time counted. After calculating the call charge on the basis of the call rate, the call charge and the charge information are reported to the charge control unit 7 and the report counter control unit 6, and then the call forwarding request is sent to the originating exchange 1. The subscriber call termination signal is transmitted to terminate the call route 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 method for transferring a call to another country subscriber according to an embodiment of the present invention, the country guide may not only perform a call transfer service between subscribers from other countries and subscribers from other countries. 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.
