Abstract

PURPOSE: A method for displaying the balance of a call and the time used to a prepaid card subscriber in a mobile communication system is provided to eliminate time and procedures required in using a prepaid card by displaying the balance and the time used through an SMS in case that a prepaid card subscriber uses his card. CONSTITUTION: If a prepaid card subscriber makes a call, an MSC(Mobile Switching Center) transmits an IAM signal to an SSP(Service Switching Point)(1). The SSP, after judging whether it is an intelligent call, asks an SCP(Signaling Control Point) whether the caller is a prepaid card subscriber(2). The SCP searches its own database to judge whether the caller is a prepaid card subscriber, and reports a result to the SSP(3). The calling MSC, receiving the result from the SCP, transmits the IAM signal to a subscriber in the called MSC(4). The called MSC transmits an ACM signal to the calling MSC in order to transfer the information of the called subscriber(5). In case that the called subscriber accepts the call, the conversation between them is made as the called MSC sends an ANM signal to the calling subscriber(6,7). Afterward, the SSP transmits billing data and a service time to the SCP if the call is finished(16). The SCP transmits information for the balance and the time to an SMS(17). The SMS transfers the information of the balance and the time to the calling MSC(18). Succeedingly, the calling MSC delivers and displays the balance and the time to the calling terminal(19).

Method for displaying balance and using time to pre-paid service subscriber in mobile communication system}

The present invention relates to a method for displaying a call balance and usage time to a prepaid card subscriber in a mobile communication system. Particularly, a mobile communication system for displaying a call balance and usage period to a prepaid card subscriber's terminal as a text service to a prepaid card subscriber. The present invention relates to a method for displaying a call balance and usage time to a prepaid card subscriber.

Hereinafter, a prepaid card service procedure according to the prior art will be described with reference to the accompanying drawings.

1 is a diagram illustrating a system connection configuration between a general mobile communication switch and an intelligent network, and FIG. 2 is a flowchart illustrating a method for guiding call balance and usage time to a prepaid card subscriber in a mobile communication system according to the related art. to be.

When the prepaid card subscriber is issued, a call request (IAM) is performed from an exchange 200 (hereinafter referred to as MSC) 200 to a service switching point (SSP) 310 serving as an intelligent network 300 switching center (1).

The SSP 310 transmits an information analysis request (AnaInfo) message of a prepaid subscriber to a signaling control point (SCP) 340 that performs intelligent network service control (2).

Subsequently, the SCP 340 makes a channel assignment request (SZRES) to the IP 330 in order to analyze the current information of the calling subscriber, such as the charging status and the period of use of the prepaid card subscriber (3), and broadcasts to the calling exchange. In order to send the IP 330 notifies (szres) the channel information to the SCP 340 (4).

Subsequently, the SCP 340 notifies the SSP 310 of the signal (ConnectRes) for establishing a call channel between the IP 330 and the SSP 310 (5), and the SSP so that the prepaid card subscriber can know the balance and the period of use. In step 310, the IMS 200 transmits an access signal (IAM) to the IP for notification of the announcement to the calling MSC 200 (6).

Subsequently, the connection signal CON is transmitted from the IP 330 to the SSP 310 for the prepaid card balance and the term of use announcement (7), and the SSP 310 for the prepaid card balance and the term of use announcement. In step 8 transmits the connection signal (CON) to the original originating MSC (200).

Subsequently, the prepaid card balance and the period of use announcement are transmitted to the terminal 100 (9), and the release (REL) signal is released from the SSP 310 to release the resource used for the allocation of the announcement from the first originating exchange. 330 and transmit (10).

Upon receiving the prepaid card subscriber inquiry, SCP 340 examines its database and notifies the SSP 310 whether or not the prepaid subscriber is a prepaid subscriber (receives AnaInfoAck) 11.

Subsequently, the outgoing exchange notified by SCP 340 receives the subscriber at the destination exchange according to the internal processing scheme of the exchange such as number translation, outgoing line occupancy, and storage of incoming / outgoing subscriber information in order to receive the incoming subscriber. The call request signal IAM is transmitted (12).

Sending signal (ACM) that transmits the information of the called party to the calling exchange with the relay line connected to the calling party with the exchange information obtained from the calling SSP 310, the calling party (13), and the subscriber at the called exchange answers the call. When it is done, it sends a response signal (ANM) to the subscriber in the calling exchange (14). Therefore, a call (CONVERSATION) is established between the called party and the called party (15).

Subsequently, after updating the resource release information of the subscriber belonging to the destination side exchange in the database inside the exchange, the release message signal REL of the resource is transmitted to the source side SSP 310 exchange (16).

Subsequently, the first sender exchange transmits a signal REL (17-21) indicating that the called party releases resources, and the SSP 310 sends a resource release response signal (RCL) of the subscriber belonging to the first calling exchange. (22).

Subsequently, the SSP 310 transmits a response signal indicating that the first prepaid card subscriber released the relay line to the called party (RLC) (23).

Looking at the problems in the prior art, first, the prepaid card subscriber has a problem that can only be confirmed by the voice announcement, the amount and the period of use used during the transmission.

Second, there is a problem that the prepaid card subscriber follows the time and procedure used by listening to the announcement when using the prepaid card.

Third, system performance degradation caused by announcements and system resources associated with prepaid card services are caused.

Accordingly, the present invention has been made to solve the above-mentioned problems according to the prior art, the object of the present invention is to prepaid card subscribers SMS SMS instead of eliminating the procedure to confirm the balance and the period of use only when using the prepaid card by announcements The present invention provides a method for displaying a call balance and use time to a prepaid card subscriber in a mobile communication system to eliminate the time and procedure required when using a prepaid card by displaying the call balance and use period on a prepaid card subscriber terminal.

In addition, another object of the present invention is to reduce the system performance and inefficiency of the system resources associated with the prepaid card service caused by the prepaid card service provider to broadcast the call balance to the prepaid card subscriber in the mobile communication system It is to provide a method for displaying the use time.

In addition, another object of the present invention is to allocate the system resources allocated for the prepaid card announcement to use other supplementary services by eliminating the procedure of the prepaid card subscriber that the prepaid card subscriber had to follow when using the service. The present invention provides a method for displaying a call balance and usage time to a prepaid card subscriber in a mobile communication system.

The technical principle according to the present invention for achieving the above object will be described briefly.

First, the prepaid card subscriber sends a call request signal (IAM) from an arbitrary exchange (MSC) to an SCP serving as an intelligent switching center. The SSP sends the information (AnaInfo) of the prepaid card subscriber to the SCP in charge of controlling the intelligent network service, and the SCP informs the SSP of the presence or absence of the prepaid subscriber and the information of the prepaid subscriber. When the SSP is determined to be a prepaid card subscriber, the SSP requests the call establishment (IAM) to the subscriber at the called side exchange, and the called side exchange notifies the SSP of the called subscriber information transfer (ACM).

The called party at the called side exchange responds (ANM) to the SSP and places a call on the original originating exchange. After the call, the calling party sends the release message to the called party. The receiving / receiving side receiving the release message transmits a Release Response (RLC) message to the receiving / receiving side, and omits announcement from the existing IP connection as in this scheduler. The calling / receiving party responds with the release, and immediately afterwards, the SSP sends the billing data and duration request to the SCP. SCP transmits billing data and period of use information to SMS, SMS keeps balance and period of use information at originating and receiving exchange and displays balance and period of use on terminal.

After all, in the mobile communication system according to the present invention, a feature of the method for displaying call balance and usage time to a prepaid card subscriber is a mobile communication system using an incoming / outgoing exchange and an intelligent network system with SSP, SCP, SMS, and IP. In the method for displaying the call balance and the usage time to the prepaid card subscriber, when the prepaid card subscriber transmits a call request signal to the SSP of the intelligent network system through the switch, it is determined whether the requested signal is an intelligent network call, Inquiring whether the calling subscriber is a prepaid subscriber, searching the database in the SCP to determine whether the subscriber is a prepaid card subscriber, and then notifying the SSP of the result; Transmitting, by the SSP, a call request signal to a subscriber in the called exchange, and transmitting the information of the called subscriber to the calling exchange through a relay line connected to the calling party with the exchange information obtained from the calling SSP; When the subscriber at the called exchange answers the call, transmitting a response signal to the subscriber at the calling exchange to perform a call between the called / calling subscribers; After updating the resource release information of the subscriber belonging to the called party exchange in the database inside the exchange, the resource release message signal is transmitted to the calling party SSP, and the calling party sends a signal indicating that the called party releases the resource to the first calling party. Transmitting to the exchange to which the subscriber belongs; The SSP transmits billing data and usage period after the prepaid card subscriber's call to the SCP, and transmits the call balance and usage period bunker from the SCP to the SMS; In the SMS, the balance and the period of use information are transmitted to the calling exchange, and the balance and the period of use are transmitted to the terminal and displayed on the terminal.

Hereinafter, after briefly explaining the overall operation of each system when using a prepaid card and the definition of the prepaid card, a detailed description will be given of a method for displaying a call balance and use time to a prepaid card subscriber in a mobile communication system according to the present invention. Let's see.

First, the definition of a prepaid card service (PPS: Pre-paid Service) is a service that receives and provides a service fee (currency) in advance by means of a prepaid card, credit card, bank account, etc. from a user. According to the talk time, the call charge is immediately deducted from the prepaid amount, and when the prepaid amount is 0 ", outgoing service is prohibited. All rental terminals or subscribers to the service provider can receive this service. PPS subscribers include the nature of alternative billing, which allows a certain amount of money to be allocated to multiple terminals within the prepaid amount.

1 is a diagram illustrating a system connection diagram between an MSC and an intelligent network when a prepaid card subscriber uses a prepaid card. The SCP 340 of the intelligent network system 300 shown in FIG. 1 provides a service control logic and provides subscriber information. It is a device that provides a subscriber database and enables online and real-time processing of a large amount of transactions.

SMS 32 is in charge of short service processing, IP 330 provides additional support of intelligent network resource management service, performs voice guidance, voice recognition, voice synthesis, tone generation functions, It is separated, but it is physically combined with the service switcher to enable implementation.

In addition, the SSP 310 requests the intelligent network service call determination function, requests control information related to the intelligent network service from the SCP 340, and performs the role of an electronic exchange to complete the service according to the SCP 340 information, and the existing transport network layer. It is the gateway to connect the exchange and intelligent network service network.

A method for displaying call balance and usage time to a prepaid card subscriber in a mobile communication system according to the present invention using a system having such a configuration will be described step by step with reference to FIG. 3.

3 is a flowchart illustrating a method for displaying a call balance and usage time to a prepaid card subscriber in a mobile communication system according to the present invention.

First, when the prepaid card subscriber makes a call, the MSC 200 transmits a call request signal IAM to the SSP 310 serving as an intelligent switching center (1).

Then, the SSP 310 determines whether the call is an intelligent network call, and inquires whether the calling subscriber is a prepaid subscriber to the SCP 340 which controls the intelligent network service (2).

Upon receiving the prepaid card subscriber inquiry, SCP 340 notifies the SSP 310 whether or not the calling subscriber is a prepaid subscriber by examining its database (3).

Upon receipt of notification from SCP (340), the originating exchange will send a call request signal to the subscriber at the terminating exchange according to the exchange internal processing skimmer such as number translation, occupancy line occupancy, storage of incoming / outgoing subscriber information, etc. IAM) (4).

Subsequently, a signal (ACM) for transmitting the information of the called subscriber to the originating exchange is transmitted through the relay line connected to the originating party with the exchange information obtained from the originating SSP 310 (5).

When the subscriber at the called exchange answers the call, an answer signal (ANM) is transmitted to the subscriber at the calling exchange (6), and a call is established between the called / calling subscriber (7).

After updating the resource release information of the subscriber belonging to the destination side exchange to the database inside the exchange, the resource release message signal (REL) is transmitted to the originating SSP 310 exchange (8), and then to the first originating exchange. The called party sends a signal REL indicating that the resource has been released (9-11).

Subsequently, the resource release response signal (RLC) of the subscriber belonging to the original originating exchange is transmitted to the SSP 310 (12), and in the SSP 310, the response signal (RLC) indicating that the first prepaid card subscriber releases the relay line resource. It is delivered to the called party (13-15).

Subsequently, the SSP 310 transmits the billing data and the usage period after the prepaid card subscriber's call to the SCP 340 (16), and transmits the call balance and the usage period information from the SCP 340 to the SMS 320. (17).

SMS 320 transmits the information of the balance and the period of use to the calling exchange (18), and the calling side exchange 200 transmits the balance and the period of use to the terminal 100 to display on the terminal 100 (19).

In the mobile communication system according to the present invention as described above, the method for displaying the call balance and the usage time to the prepaid card subscriber is a new new function, after which the prepaid card subscriber can check the call balance and the usage period from the terminal. In addition, the use of prepaid cards can be enlightened, and prepaid card subscribers do not need to listen to announcements when calling. In addition, service providers do not need to send announcements, so it is unnecessary to allocate voice trunks between exchanges and IPs, which is beneficial to system resources and performance. Therefore, the characteristics of the effects of the present invention are as follows.

First, there is an advantage in that the prepaid card subscriber can reduce the time and procedure required when using the prepaid card by eliminating the procedure of confirming the balance and the period of use when the prepaid card is used only by announcement.

Second, there is an advantage that can be removed by the prepaid card service provider to perform the announcement, the system performance degradation and the inefficiency of the system resources associated with the prepaid card service.

Third, there is an effect that the prepaid card service provider can dedicate the system resources allocated for the prepaid prepaid card announcement by using other supplementary services by eliminating the procedure of the announcement that the prepaid card subscriber should follow.
