The present invention has been made in order to provide a call processing method, and an object of the present invention is to provide a call charging service and a credit call service call processing method to provide an incoming charge and a credit call intelligent network service to an existing telephone exchange.

Incoming billing services allow companies with many customer consultations to provide telephone services that are charged to the enterprise itself, without charges to the caller for incoming phone calls related to sales activities.

Companies can receive various additional services, such as registering different phone numbers to receive reservations / inquiries by calling memory / time zone / day.

The signal calling service is a post-payment method that charges a call charge to a third-party credit billing number instead of the calling party number, so that the caller can talk without cash. Credit call service subscribers can be provided with a variety of additional services, such as limiting calls by call destination / time zone.

Incoming billing service gives service subscriber a special number, not a phone number of general called party, that is, service identification number and called billing number, so that the call charge of incoming call is sent to called party (service subscriber) instead of caller (service user). It is a service that you charge.

The credit call service is a service that charges a call fee used by a service user to a third-party credit charge number. That is, by charging a service subscriber's credit number instead of the calling party's number, which gives the subscriber a credit number and password, the service user can make a call without using cash.

In order to achieve the above object, the present invention provides an incoming billing service and a credit call service call processing method of an SSP that performs an intelligent network service function. A method of determining an intelligent network service type by a user's intelligent network call attempt and trigger is provided.

FIG. 3 is a flowchart of performing an incoming billing service and a credit call service function. When the circuit registration control recognizes a relay line occupancy or a subscriber hook off (101), the basic call processor assigns an R2 / DTMFR signaling device assignment to the signaling device control. (102). Signaling device control (103) passes the collected digits to traffic control upon receiving a digit from the calling switching center or originating subscriber, the traffic control requesting the number translation function (104) to receive the result. As a result of the translation, the general call interacts with related functions to construct the call (105), and if the intelligent network service, the BCPI (63) block informs the intelligent network service call. When the BCPI 63 block receives the recognition of the intelligent network service from the traffic control, the BCPI 63 block determines the corresponding intelligent network service using a trigger table (106). If it is determined as an incoming billing service, the FPSC 66 block is requested, or if it is determined as a credit call service, the CCSC 68 block is requested to perform the service. The flow performed according to the type of each intelligent network service call is as follows.

First, as an incoming billing service, the FPSC 66 block asks the FPSM 67 block whether the service is provided for the received incoming billing number (107) and collects outgoing subscriber numbers if the service is available (109, 110, 111). If it is impossible, and transmits the announcement or tone to the calling subscriber (108) and ends when the calling subscriber hooks (Hook On).

The FPSC 66 block forwards a command-providing operation primitive to the FPOE 56 block requesting information to the SCP to obtain a qualified check for the incoming billing number and the actual routing number prior to service call connection (112). Wait for the result to be received from the SCP (113).

The FPSC 66 block, which received the result as a response primitive 114 for the command-providing operation, divides the result (115) and sends the corresponding recording announcement or tone to the calling subscriber when the service is unavailable. Request 116, if available, requests routing to the routing control with the called number received (117). The following process is a call completion process, which is the same as the call completion process of the credit call service.

Next, as a credit call service, the CCSC 68 block asks the CCSM block 69 whether the service is provided (118) and if it is not possible, informs the calling party of the announcement or tone (119). Hook On) to exit. If the service is available, the CCSC 68 block collects the calling number (120, 121, 122), requests the signaling device control to allocate the DTMFR signaling device to associate the tone with the calling party (123, 124) and the service user enters digits (information). (125).

The combination of information entered by the calling subscriber is 1) credit billing number, 2) credit billing number + password, and 3) credit billing number + password + called party number.

When the digit received from the signaling device control is delivered, the CCSC 68 block performs the credit call service using the received information.

The CCSC 68 block uses the information gathered earlier to determine whether to accept the call to the called number, if the credit number or credit number and password have been received prior to the service call connection. It sends a command-operation primitive requesting information to the CCOE 58 block (126) and then waits to receive a result from the SCP (127).

When the CCSC 68 block receives the additional information request 128 as an additional information request primitive and not the result, the CCSC 68 connects the recording announcement broadcast requested by the SCP to the calling party (129) to allow the sender to press an additional digit (l30). ),

When the CCSC 68 block receives the additional digit from the calling party, the CCSC 68 transmits the information to the CCOE 58 block as a response primitive for the information transmission / reception operation (131) and waits for reception of the result (132).

The CCSC 68 block, which has received the result as a response primitive for the command providing operation (133), analyzes the result (134) and sends the corresponding recording guide or tone to the service user when service is unavailable (135). It requests to the call processing unit and, if available, requests routing to the received call number from the routing control (117). Now, the call completion process of the incoming billing service and the credit call service will be described. The routing control requests the circuit registration control / time switching control / space switching to configure the call (136). If the called party is the relay line, it requests the signaling device control of the ASS (1) on which the called party is mounted to allocate the R2 MFC signal device to perform inter-station signaling. When the hook-off from the called party is recognized by the circuit matching control (139) and notified to the FPSC 66 or CCSC 68 block of the corresponding service, the billing management is notified of the intelligent network service charging start (140).

If the call-on hook is recognized by the circuit matching control (141), the charging management is notified of the termination of the intelligent network service charging (142), and the circuit matching control / time switching control / space switching block is requested to be disconnected. A call is requested to the destination side line matching control to transmit a relay line omnidirectional disconnect request signal, and ends (143,144).

Therefore, the present invention has the following effects.

1) Electronic switchboards that directly perform intelligent network services Electronic switchboards can be implemented with only a few software changes and additions without hardware changes.

2) Existing exchange can accept intelligent network service by modifying only route information without changing hardware and software.

3) The incoming billing service greatly increases the volume of calls related to telemarketing since there is no burden on customers for calls related to the company's business activities by the caller paying the caller without paying the call charges.

4) The credit call service can greatly increase the volume of public phone calls because callers can make calls without cash.
