The present invention relates to a method and a system for controlling packet charging and time charging in an intelligent network system. More specifically, when receiving a packet data service in the WCDMA-based intelligent network system, a method for granting the charge according to the packet data service, according to the charging information previously set by the subscriber to the packet charging or time charging; and Accordingly, the present invention relates to a charging system.

BACKGROUND With the rapid development of electronic and communication technologies, various wireless communication services using wireless networks have been provided. In particular, a wireless Internet service has recently emerged that provides a communication service using the Internet through a wireless communication network while the user of the mobile terminal moves without restriction of a place. Therefore, the subscribers of the mobile communication service can freely move and talk with the other party at any time and anywhere using the wireless communication service, and various information such as news, weather, sports, stocks, exchange rates, and traffic information through the wireless Internet service. It can be provided in a variety of forms, such as text, voice, image (Image).

In order to provide such a service, a mobile communication system has been developed through a first generation analog AMPS (Advanced Mobile Phone Systems) method and a second generation cellular / personal communication service (PCS) method. Recently, IMT-2000 (International Mobile Telecommunication-2000), a third generation high speed data communication, has been used. IMT-2000 was developed for personal mobility guarantee and high-speed data transmission to ensure mobility between countries by integrating systems of countries using different wireless access standards. It is asynchronous with Code Division Multi Access (CDMA) 2000, which is a synchronous method. It was developed separately from Wideband CDMA (WCDMA).

Since the WCDMA system uses a wider bandwidth than the CDMA method using a similar noise code unique to the subscriber's communication channel, the frequency selective fading is excellent, and the bandwidth is increased when the same data is transmitted, thereby increasing the processing gain. As a result, the interference is reduced, which is suitable for transmitting a large amount of data. Accordingly, the Packet Data Service System (hereinafter referred to as 'GPRS') in WCDMA guarantees high speed transmission of packet data.

Meanwhile, general CDMA and WCDMA communication networks have provided uniform and simple services that are applied uniformly to all subscribers. Accordingly, call processing and billing principles have been mainly dealt with by the caller, and all call controls are fixedly identical by the exchange. Applied. Accordingly, the new service had to change the software of the exchange as a whole, thus providing the same service to all customers.

In order to solve this problem, to enable the application of new services developed without changing the software of the exchange, an IN (Intelligent Network) can be proposed to provide a variety of additional communication services directly to the CDMA network and WCDMA network Was applied. With the provision of such an intelligent network, service modification and supplementation can be processed quickly and accurately, and economical and efficient operation of the network becomes possible.

In the conventional charging method for a subscriber who receives a packet data service through the WCDMA-based intelligent network system, a packet charging type that performs charging based on data usage (that is, packet usage) is mostly used. However, in such a packet charging method, it is difficult for the subscriber to measure the amount of charges and the subscribers have a lot of complaints due to low understanding of the charges. This necessitates the development of a billing product that is easy for customers to recognize in order to activate the data service of the mobile communication network.

On the other hand, the time billing method used in the voice call service is a high level of understanding of the subscriber, it is possible for the subscriber to predict the charge. Accordingly, a method of applying a conventionally used time charging method as a charging method for packet data services of a WCDMA intelligent network has been proposed in the 3rd Generation Partnership Project (3GPP), an international standard. As the time billing method is proposed, the mobile operator operates the packet billing method and the time billing method at the same time, and allows the subscriber to select and apply the billing method that is advantageous to him.

However, if the current telecommunications carrier applies the time billing scheme proposed in accordance with international standards to the packet billing infrastructure currently applied to the WCDMA intelligent network system, it checks the billing scheme selected by the subscriber and accordingly Since the infrastructure control method to impose the cost is not proposed, the time billing method is not practically applied. Accordingly, there is a need for a method and system for controlling packet charging and time charging in a WCDMA intelligent network system.

In order to solve such a problem, the present invention provides a packet data service according to the charging setting information set by the subscriber in advance for packet charging or time charging when providing a packet data service in an intelligent network system based on WCDMA. It provides a method for granting a charge and a charge grant system for the same.

In order to achieve the above technical problem, the charging control method according to an embodiment of the present invention provides the charging according to the charging information selected by the subscriber in the intelligent network system that supports time charging according to the usage time of the packet data service and packet charging according to the packet usage. CLAIMS 1.

2 is a flowchart illustrating a packet charging and time charging control method according to an embodiment of the present invention.

When the request for providing the packet data service through the intelligent network 130 is transmitted from the mobile terminal 110 of the subscriber, the SGSN 1240 transmits the received packet data service providing request signal to the SCP 1310. At this time, the registration information of the mobile terminal 110 is confirmed and transmitted through the HLR 1230. Here, the packet data service providing request signal transmitted from the SGSN 1240 and the registration information of the mobile terminal 110 may be transmitted through an Initial_DP_GPRS message. Here, the Initial_DP_GPRS message is described in 3GPP, which is an international standard, and a detailed description thereof will be omitted.

When the SCP 1310 receives the packet data service request request signal and the registration information of the mobile terminal 110 (S210), whether the subscriber is a 2G network subscriber or a 3G network subscriber through a stored network information element, or a CDMA network subscriber. Whether it is a subscriber or a WCDMA network subscriber, a packet charging service subscriber, or a time charging service subscriber. At this time, the network information element may be checked through the subscription information of the subscriber stored in the customer management device 1360 (S220).

If it is confirmed that the subscriber is a time billing subscriber through the verification of the network information element (S230), the time billing rate information of the subscriber stored in the SCP 1310 is checked (S240).

In addition, SCP 1310 checks when the packet data service is provided to the subscriber and when the packet data service is stopped through interworking with the SGSN 1240. As data packets are transmitted from the SGSN 1240 to the mobile terminal 110, the settlement of the packet data service time is started, and when the transmission of the data packet is terminated, the settlement of the packet data service time is terminated. The packet data service time used is calculated (S242).

Upon request of the end of packet data service from the subscriber, SCP 1310 forwards the set packet data service time and time billing rate information to DSCP 1320.

The DSCP 1320 calculates time billing to be charged to the subscriber according to the received packet data service time and time billing rate information (S244). At this time, information such as the calculated time billing and packet data service time is transferred to the data billing analysis system 1330 and stored.

Here, when it is confirmed in step S230 that the subscriber is a packet charging subscriber through the identification of the network information element, SCP 1310 checks the stored packet charging rate information of the subscriber and transmits it to the DSCP 1320 (S250). .

In addition, SCP 1310 transmits a Connect message or Continue message through interworking with SGSN 1240, checks whether the data packet is transmitted, and the amount of data packets transmitted through SGSN 1240 and GGSN 1250. Check (S252).

The SCP 1310 checks the amount of data packets transmitted to the subscriber's mobile terminal 110 from the SGSN 1240 and the GGSN 1250, and the information about the amount of data packets transmitted and the packet charging rate information are DSCP ( 1320). The DSCP 1320 calculates packet charging to be charged to the subscriber according to the packet charging rate information and the amount of data packets provided (S254). At this time, the type of data packet transmitted, the amount of data packet, packet charging, and the like are transmitted to the data charging analysis system 1330 and stored.

Here, in steps S320 and S330, the network information element of the subscriber is checked to determine whether the subscriber is a packet charging service or a time charging service subscriber, and accordingly calculating the time charging rate or the packet charging rate according to the network information element. It can be subdivided according to its type.

3 is a flowchart illustrating a method of confirming a packet charging rate or a time charging rate according to various network information elements according to an embodiment of the present invention.

Through step S220 of FIG. 2, the SCP 1310 checks network information elements stored to calculate a time charging rate or a packet charging rate. First, SCP 1310 checks whether the subscriber is a 2G network subscriber or a 3G network subscriber. Such confirmation of 2G or 3G network subscribers, 2G network only supports packet billing without time billing, but 3G network supports both time billing and packet billing, so in case of 2G network subscribers, packet billing to be described later Alternatively, the packet charging subscriber information can be quickly determined without determining additional network information elements such as time charging subscriber determination, and the traffic generated in estimating the charging rate in SCP 130. This is to make it as small as possible.

Here, the confirmation of the 2G network subscriber and the 3G network subscriber can be confirmed through terminal information and subscription information of the subscriber stored in the HLR 1230 or the customer management device 1360 (S2310). At this time, it is also possible to further check whether the subscriber is a CDMA network subscriber or a WCDMA network subscriber.

If it is confirmed through the step S2310 that the subscriber 3G network, SCP (1310) checks again via the network information element whether it is a packet charging service subscriber or a time charging service subscriber (S2320).

Here, if it is confirmed that the subscriber is a time billing service subscriber, SCP 1310 again checks whether the subscriber is a discount target through the network information element (S2330).

If it is confirmed that the subscriber is a discount target subscriber, the discount information is checked and the time billing rate is calculated by reflecting the confirmed discount information (S2340).

SCP 1310 then performs a step after S240 in which charging is performed by reflecting the calculated time charging rate in the usage time of the subscriber's data packet service.

In this case, if it is determined in step S2330 that the subscriber is not a discount target subscriber, the step after S240 of performing the charging by calculating the general time charge rate without reflecting the discount information is performed.

On the other hand, if the subscriber confirms that the subscriber is a 2G network subscriber that does not support time billing through step S2310, or confirms that the subscriber is a 3G network subscriber and a packet billing service subscriber through step S2320, SCP 1310 again uses a network information element. It is checked whether or not the discount target subscriber (S2350).

If it is confirmed through the step S2350 that the subscriber is a discount target subscriber, the discount information is checked, and the packet charging rate is calculated by reflecting the confirmed discount information (S2360).

However, if it is determined in step S2350 that the subscriber is not a discounted subscriber, the general packet charging rate without discount information is calculated.

The calculated packet charging rate information is transmitted to the DSCP 1320 through the S250 step, and performs the step after S250 for calculating the packet charging according to the transmitted data packet amount.

Here, whether the 3G network subscriber or the 2G network subscriber, the packet charging subscriber or the time charging subscriber, and the discount target subscriber according to steps S2310 to S2360 are 2 bit data fields ('00 to 11 ') in the Initial_DP_GPRS message. It can be displayed through.

If the data field is displayed as '00', it indicates that the 2G network subscriber or the 3G network subscriber is the packet charging subscriber, so that the general packet charging rate is applied.If the data field is indicated as '01', the 2G network subscriber or 3G The discounted packet charging rate is applied by indicating that the network subscriber is a packet charging subscriber and a discount target subscriber.

When the data field is displayed as '10', the general time billing rate is applied by indicating that the 3G network subscriber is a time billing subscriber, and when the data field is displayed as '11', the time field is among the 3G network subscribers. Indicate the discounted subscriber so that the discounted time charge rate is applied.

That is, the first bit may be regarded as an area indicating whether a packet charging subscriber or a time charging subscriber is used, and the second bit may be regarded as an area indicating whether to be a discount target subscriber. Accordingly, when there is no subscriber to be discounted because the discount is not applied at the time of providing the data packet service, only 1 bit may indicate whether the packet charging subscriber or the time charging subscriber is present.

2 to 3 described above, in checking the network information element in SCP 1310, first check whether the subscriber is a prepaid subscriber, and in the case of a prepaid subscriber, the prepaid payment amount for the data packet service Thereafter, the method may further include the step of performing the step after S230 only when the balance of the prepaid payment amount exists. At this time, the balance of the prepaid payment amount from time to time may be additionally included so that the data packet service no longer proceeds when the balance reaches zero.

The embodiments of the present invention described above are not implemented only through the apparatus and the method, but may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. Implementation may be easily implemented by those skilled in the art from the description of the above-described embodiments.
