Description

How to transfer services to subscribers of other countries

The present invention relates to a call transfer service method for subscribers of another country, more specifically, when a subscriber from another country requests a call transfer to a subscriber of another country according to the guide of the country. The present invention relates to a call transfer service method for a subscriber of a foreign country, which is allowed to wait until a response time to a call and connects a call of the foreign subscriber with the foreign subscriber.

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 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, 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.

Accordingly, in order to solve such a 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 be generated by performing the function, namely However, when a call is transferred to a subscriber in a country by calling its information desk or a general guide in another country, the application of the charge is applied to the subscriber. However, when the call is transferred to a subscriber in another country, 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 circumstances, and when a foreign subscriber subscribes to a call to a foreign subscriber as guided by his own country, the foreign subscriber is waiting until the foreign subscriber responds to the call. Provides the transfer service to foreign subscribers by linking the call of the foreign subscriber with the foreign subscriber, and the transfer service to other subscribers of the National Information Service, which can reasonably handle the charges incurred. The purpose is to provide a method.

According to an 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 accommodated in the originating exchange is connected to the local exchange. A first step of requesting a transfer service as guided by the exchange and waiting for the originating subscriber while the information desk calls the called subscriber accommodated at the destination exchange that is the subject of the transfer service required by the originating subscriber; A second step of allowing the called subscriber to accept the call transfer service, and setting a call path between the calling subscriber and the called subscriber and determining whether the calling relay call processor is designated as a charging designated point. If it is determined that the originating call processing unit is designated as the charge designation point, A fourth step of storing the billing information for the corresponding call in the billing information storage and counting the talk time; and if the call is terminated, the call charge is based on the billing information stored in the billing information storage and counting the talk time. After the calculation, the billing information and the call charge data are stored in the billing storage, and the fifth step of reporting according to the guide is provided.

Preferably, in the second step, the guide station control unit sends a hook-fresh message to the incoming call processing unit, and the incoming call processing unit sends out a waiting tone to the calling station exchange based on the hook-fresh message. And the process of waiting for the calling subscriber by outputting the corresponding waiting tone to the calling subscriber.

Preferably, in the fifth step, when the originating subscriber disconnects the call first, an originating subscriber call cancel signal is transmitted from the originating exchange, and the incoming call termination part is processed based on the originating subscriber call canceling signal. The calling party call cutting message is reported to the relay call processing unit so that the call termination state is recognized by the calling relay call processing unit.

Preferably, in the fifth step, when the called party first disconnects the call, an incoming subscriber call termination signal is transmitted from the called country exchanger, and the originating relay call processing unit is further configured based on the incoming subscriber call termination signal. It is characterized by terminating the call by reporting the incoming subscriber call cutting message to the incoming call processing unit.

And, preferably in the present invention, the guide is characterized in that the billing designation point is set to the outgoing relay call processing unit according to whether or not the call target billing target required by the originating subscriber.

In addition, the guide in the fifth step of the present invention preferably outputs the billing information reported on the monitor screen and is characterized in that it is stored in a predetermined storage means.

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 FIG. 1, reference numeral 1 denotes a caller for an incoming or outgoing call for the calling party 12 connected to another calling party 12. 3 is a called station exchanger that performs an exchange function, and 3 denotes a called party exchange that is connected to an incoming subscriber 13 of another station and performs a telephone exchange function for an incoming or outgoing call to the called subscriber 13.

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 a request from the calling party 12 of the calling party exchange 1, the local switching machine 2 calls the called party 13 of the called party exchange 3 so that the calling party 12 and the called party ( A guide 9 for carrying out a call transfer function according to a relay call is connected by connecting a call between 13).

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. Incoming call processing unit (4), outgoing call processing unit (5), billing information storage unit (6), billing accounting unit (7), guide stand controller (8), billing control unit (10), billing storage unit (11) ), A counter 14 and the like.

Here, the incoming relay call processing unit 4 is a block responsible for relay line signal control and call processing for a call received from the originating station exchange 1 to the local exchange 2, and the hook to be described later in the present invention. When a fresh signal is reported, a waiting tone is sent to the calling station switch 1 so that the waiting tone is output to the calling subscriber 12.

In addition, the outgoing relay call processor 5 is responsible for relay line signal control and call processing in order to transfer the call signal applied from the incoming relay call processor 4 to the destination station switch 3, and a call transfer service. As a block for processing information on billing generated during execution, the function of processing information on billing generated when performing a transfer service provided to the outbound relay call processor 5 is transmitted to the incoming call processor 4. You can also grant.

In addition, the billing information storage unit 6 under the control of the originating relay call processing unit 5, the information according to the billing when the call connection between the calling party 12 and the called party 13 (ie, call start time / billing) Rate application criteria / calling number / calling number / guide number), and the billing calculation unit 7 controls the billing information under the control of the originating call processor 5 when the call is terminated. It is a block that performs a function of calculating a call charge based on the charging information read out from the storage unit 6, and the counter 14 is the originating subscriber 13 and the originating call under the control of the originating call processor 5; It is a block for performing a counting operation for the talk time from the time point at which the call between the subscribers 12 is performed.

In addition, the billing control unit 10 is a block for performing a function of storing the billing information for the call charges and other call information notified from the outgoing relay call processing unit 5 in the billing storage unit 11 connected to the rear end. In addition, the charging storage unit 11 is, for example, a magnetic tape (MT) or a diskette unit (DKU) is a block for performing the function of storing the charging information.

In addition, the guide control unit 8 controls the ISDN protocol and call processing of the guide 9 connected to the ISDN (2B + D), and the call transfer from the originating subscriber 12 to the relay call is requested. When the incoming call processor 4 and the outgoing call processor 5 is connected to perform a call transfer function for the relay call and the other subscribers by the calling subscriber 12 If the call forwarding service is requested, the called party 13, which is the target of the call transfer service, is called while the calling party 12 is waiting, and then the calling party (depending on the answer of the called party 13) is called. 12) and the transfer function between the called subscriber 13 is performed.

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 12 of the calling party switch 1 calls the guide 9 connected to the local switching station 2 to make a call (step 20), and the calling party 12 calls the guide ( 9), if a call connection is requested to any called party 13 subscribed to the destination switching center 2 (step 22), the operator of the guide 9 performs a hook-flash operation. Accordingly, the guide stand control unit 8 reports the hook-fresh message to the incoming call processing unit 4 (step 24), and the incoming call processing unit 4 is based on the hook-fresh message. A waiting tone is sent to the exchange 1, wherein the waiting tone applied to the originating exchange 1 is output to the calling party 12 (step 26).

Subsequently, the information desk control unit 8 applies the telephone number of the called party requested by the calling party 12 to the calling relay call processor 5, and the calling relay calling processor 5 is authorized. ) Performs a number translation for the corresponding telephone number and then requests a call to the called party 13 to the called party exchange 3 to which the called party 13 corresponding to the phone number is subscribed. The state exchange 3 sends a call signal to the called party 13 to call the called party 13 (step 28).

On the other hand, the called station exchange 3 calls the called party 13 and sends out a ring back tone signal for reporting the call state to the guide 9 and the ring back call. The tone signal is transmitted to the guide 9 through the guide controller 8 (step 30).

On the other hand, in response to the call in step 28, when the called party 13 hooks-off the receiver / receiver (step 32), between the called party 13 and the guide 9 A call path is set so that a call is made between the called party 13 and the operator of the guide 9 (step 34).

In such a state, the guide 9 inquires the called party 13 of the intention to connect the transfer service, and when the called party 13 permits the transfer of the transfer service, the guide 9 ) Reports the call transfer service connection to the incoming call processing unit 4 via the guide stand controller 8 (step 36). Here, the incoming call processing unit 4, which has reported the call transfer service connection, cuts off the waiting tone transmitted from the step 30.

In the above step, the incoming call processing unit 4, which has received the call transfer service connection signal from the guide station control unit 8, is the originating relay call processing unit 5 among the messages notified from the guide station control unit 8. The outgoing relay call processor 5 that stores the processor and channel information, the charging condition, and the call cancellation condition of the processor, and receives the call transfer service connection signal from the guide controller 8; Stores the processor and channel information of the incoming call processor 4 of the received message.

Subsequently, the originating relay call processor 5 checks the presence / absence of the charge designation point provided from the guide stand controller 8 and sets the originating call processor 5 as the charge designation point. If the outgoing call processing unit 5 is set as the charge designation point (YES in step 38), the outgoing call processing unit 5 should perform the billing transfer after the call cutting. After storing the state to recall the information required for billing, such as PPM code, the number of the calling subscriber, the number of the called subscriber, the guide number, the guide number to be billed report in the message received from the guide control unit (8) After storing in the billing information storage section 6 (step 40), the counter 14 is set so that the talk time is counted.

Subsequently, the incoming call processor 4 and the outgoing call processor 5 are matched based on the stored processor information, channel information, etc. of the called party exchanger 1 and the incoming call processor 4. A call route between the calling relay call processor 5 and the called party exchange 3 is set so that the call between the calling party 12 and the called party 13 is carried out (step 42).

On the other hand, if it is determined in step 38 that the originating relay call processor 5 is not designated as the charging designated point (NO in step 38), the process proceeds to step 42.

The calling party calling termination signal transmitted from the calling party exchange 1 by first cutting the calling party while the call between the calling party 12 and the called party 13 is performed through the above process. Is transmitted to the incoming call processor 4 (step 44), the incoming call processor 4 forwards the calling party call cutting message to the outgoing call processor 5 (step 46). It is determined whether the call processing unit 5 has been designated as the charging designated point (step 48).

If it is determined that the originating relay processing section 5 is not designated as the charge designation point (NO in step 48), the originating relay call processing section 5 transmits a caller termination signal to the destination station exchange 3; The called party 13 is notified of the state in which the call has been terminated (step 50).

On the contrary, if it is determined in step 48 that the originating relay call processor 5 is designated as the charge designation point (YES in step 48), the originating relay call processor 5 sends the billing information storage unit 6 to the billing information storage unit 6. After applying the stored billing rate application standard information and the talk time revealed by the counter 14 to the billing calculation unit 7 to calculate the call rate for the call, the call rate and the billing information storage unit 6 In step 52, the charging information is stored in the charging control unit 10 and the guide stand control unit 8.

Thus, the charging control unit 10 stores the corresponding charging information in the charging storage unit 11 (step 54), and the guide stand control unit 8 applies the charging information to the guide 9 by applying the charging information. The billing information is output through the monitor of the guide 9 and the billing information is stored in a storage means provided in the guide 9, for example, a hard disk (HARD DISK) (step 56).

Therefore, the operator operating the guide 9 can not only easily check the call charge and billing information for the call, but also separately to calculate the call charge or call information recorded in the charge storage unit 11 for the charge calculation. By being able to deliver to the operating computer, the call charges for the call can be accurately billed.

On the other hand, the present invention has been described a case in which the calling party 12 first disconnects the call in step 44, but as another example, the called party 13 first cuts the call in step 44 from the destination exchanger (3) When the called party call cutting signal is transmitted to the outgoing call processor 5, the outgoing call processor 5 sends the called party call cutting message to the incoming call processor 4 and then the outgoing call processor 5 ) Is set as the charge specification point.

As a result of the determination, if the outgoing call processing unit 5 is not set as the billing designation point, the call is disconnected, while the outgoing call processing unit 5 is set as the billing designation point; Follow step 56.

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.
