Abstract

PURPOSE: A charging method for a call drop generated in an intelligent network is provided to process non-charging for a dropped call generated due to a failure in an air section, thereby improving the reliability and the quality of a service. CONSTITUTION: An SSP(Service Switching Point) receives a call release message from an outgoing switching network due to an air failure, reports the call release message to an incoming switching network to release an originated call, and transmits a call result report message to an SCP(Service Control Point)(S101). The SCP analyzes an access denied message and judges time of a dropped call(S102). If the call time of the dropped call is less than predetermined call time, the SCP processes non-charging for the call(S103). If the call time of the dropped call is more than predetermined call time, the SCP processes charging for the call and reflects the result in a call result report return message to transmit the call result report return message to the SSP(S104). The SSP records a termination state of an incomplete call on a charging data report message(S105).

Description

How to handle cutting call billing in an intelligent network call {METHOD FOR PROCESSING DISCONNECT CALL CHARGE AT INTELLIGENT NETWORK BUSY}

The present invention relates to a method for processing a call disconnection during an intelligent network call. More specifically, a call disconnection call for displaying a billing CDR (Charging Data Record) as a call for a call less than 10 seconds in an intelligent subscriber call is disconnected. It relates to a billing processing method.

As is well known, the intelligent network system is a system developed to provide a variety of new services and more convenient to telephone subscribers and users. Such an intelligent network system allows service implementation and network implementation to be independent of each other in an environment where many service providers and communication equipment manufacturers exist. However, the services provided by the current network are controlled uniformly by the exchange. Therefore, in order to satisfy the various needs of telephone subscribers and network operators, each time a new service is provided, the operation of the exchanges of the network is required, thereby providing a new service. There is this difficult problem. In order to solve this problem, the International Standardization Organization (ITU-T) has steadily promoted the standardization of the intelligent network system and released standardization standards such as ITU Capability Set-1 (CS-1) and CS-2.

In the case of billing processing in such an intelligent network system, conventionally, billing processing is performed by the call release of a normal calling party or a called subscriber without separately processing the cause of the radio cutoff call caused by an air section failure. Accordingly, even though the call was not terminated normally, complaints were frequently made due to unfair charges imposed on subscribers, which caused the company's reliability and quality of service to fall.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to dissatisfied subscribers by separately charging their causes for the wireless disconnect call caused by an air section failure. The present invention provides an intelligent network call disconnection call processing method that removes an element and imposes a statistical function on a wireless disconnection call so that an operator can quickly deal with an air section where the problem occurs.

In order to achieve the above object, according to the present invention, an intelligent network call disconnection call processing method is received when a service switching point (SSP) receives a call release message (REL) due to an air failure from an originating exchange network during a call. Step 101 of notifying the switching network to perform a call release and transmitting a call result report message (CRR) to a service control point (SCP);

Step 102, when the service control point SCP analyzes an access failure reason ADR of a call result report message CRR and determines whether a disconnected call is longer than a set talk time T; And

If it is determined that the call is a disconnected call less than the set talk time T, the service control point (SCP) may be configured to perform billing processing.

In the intelligent network call disconnection call processing method, when the service switching point (SSP) receives a call release message (REL) due to the air (Air) failure from the incoming call exchange network during the call, the called number of the call release message (REL) A step 201 of determining whether the translation is an incoming call;

If the called number translation is called in the 201 step, the service switching point (SSP) notifies the originating switching network of the call release message (REL) and releases the calling signal, and then services the call result report message (CRR). Step 202, transmitting to a control point (SCP);

Step 203, when the service control point SCP analyzes an access failure reason ADR of the call result report message CRR, and determines whether the call is a disconnected call with a set talk time T or more; And

If the disconnection call is less than the set communication time (T) as a result of the determination in step 203, the service control point (SCP) is characterized in that it comprises the step 204 of the billing process.

Hereinafter, a method for processing cut call charging during an intelligent network call according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a signal flow diagram illustrating a process of processing call disconnection during an intelligent network call according to an embodiment of the present invention, and FIG. 3 is a signal flow diagram illustrating a process of processing call disconnection during an intelligent network call according to an embodiment of the present invention. The intelligent network system applied to the present invention is composed of a service switching point (SSP) 100 and a service control point (SCP) 200.

The service switching point (SSP) 100 serves to switch each intelligent network call when the originating switching network 1 attempts an intelligent network call.

In addition, the service control point (SCP) 200 is a system for providing service logic for an intelligent network service, and controls various service scenarios currently provided by mobile subscribers, and performs a function of managing subscriber data and billing data. do.

Next, a method for processing a cut call charging during an intelligent network call according to an embodiment of the present invention using the above-described intelligent network system will be described with reference to FIGS. 1 and 2, and one embodiment of the present invention is an intelligent network. The following describes a method for processing a disconnected call when a call release message is received from a calling party during a normal call.

First, when the service switching point (SSP) 100 receives a release message (REL: Release Message) due to an air failure from the originating switching network 1 during a call, it notifies the called switching network 2 and sends it. After performing the call release, the call result report message (CRR) is transmitted to the service control point (SCP) 200 (S101).

Then, the service control point (SCP) 200 analyzes an access denied message (ADR) of a call result report (CRR), and if the call is a disconnected call, whether the call is a disconnected call of 10 seconds or more. Determine (S102).

At this time, if the cut-off call is less than 10 seconds (NO) as a result of the determination of step 102 (S102), the service control point (SCP) 200 is charged for (S103).

On the other hand, if it is a disconnected call of 10 seconds or more (YES), the service control point (SCP) 200 charges the result and then returns the result to the call result report return message (Crr). Reflecting and transmitting to the service switching point (SSP) (100) (S104).

Then, the service switching point (SSP) 100 records the incomplete call charging termination status as a failure of the air interface message on the charging data report message (CDR), and performs statistical processing as an outgoing incomplete call (S105). Therefore, the operator quickly measures the air section in which the problem occurs through the confirmation procedure of the statistically treated content as the incomplete call.

On the other hand, the following will be described with reference to Figures 3 and 4 for the intelligent network call disconnection call processing method according to this embodiment of the present invention, this embodiment of the present invention calls from the called party during the intelligent network normal call A method of processing a disconnected call charging when a release message is received.

First, when the service switching point (SSP) 100 receives a call release message (REL) due to an air failure from the incoming call exchange network 2 during a call, the called number translation of the call release message REL is self-networked. It is determined whether the incoming call (S201). Here, the self network means a mobile communication provider network such as "018", "019", "016", etc. The present invention is applicable to all mobile communication provider networks.

At this time, if the called number translation is self-received in the 201 step (S201) (YES), the service switching point (SSP) 100 notifies the call release message (REL) to the originating switching network (1) and send it. After performing the call release, a call result report message (CRR) is transmitted to the service control point (SCP) 200 (S202).

Then, the service control point (SCP) 200 analyzes the access failure reason (ADR) of the call result report message (CRR) to determine whether the call is a disconnected call of 10 seconds or more (S203).

At this time, if the disconnection call is less than 10 seconds (NO) as a result of the determination in step 203 (S203), the service control point (SCP) 200 is charged for (S204).

On the other hand, if it is a disconnected call of 10 seconds or more (YES) as a result of the determination in step 203 (S203), the service control point (SCP) 200 processes the charge and reports the result in a call result report return message (Crr). Reflecting and transmitting to the service switching point (SSP) (100) (S205).

Then, the service switching point (SSP) 100 records the incomplete call charge termination status as a failure of the air interface message on the charge data report message (CDR), and performs statistical processing as the outgoing incomplete call (S206). Therefore, the operator quickly measures the air section in which the problem occurs through the confirmation procedure of the statistically treated content as the incomplete call.

On the other hand, in the 201 step (S201), if the incoming number translation is not the self-received (NO), the service switching point (SSP) 100 performs the normal charging process and then statistical processing as a complete call (S207).

Although the present invention has been described in more detail with reference to some embodiments, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention.

As described above, according to the method for processing a cut call during an intelligent network call according to the present invention, the reliability of the company is eliminated by removing the dissatisfaction factor of the subscriber by performing the non-billing process for the wireless cutoff call caused by an air section failure during the intelligent network charging. And it improves the service quality, and imposes a statistical function for the radio disconnect call has an excellent effect that allows the operator to take action in the air section in which the problem occurs quickly.
