2 is a flowchart illustrating a method of charging a call for a prepaid service subscriber according to an embodiment of the present invention in a mobile communication system.

The present invention relates to a charging processing method of a mobile communication system, and more particularly, to an incoming charging processing method of a mobile communication system.

In the mobile communication system, a prepaid service is a service in which a subscriber pays a call fee in advance without paying a general subscriber's fee, such as a separate basic fee and a radio wave fee, and pays only the fee. In general, the prepaid service call rate is higher than that of the general subscriber, and the same rate applies regardless of the region. In addition, the current prepaid service can be applied only in the case of outgoing call, and the call charge is free, but the subscriber can use the incoming call service if necessary.

And each mobile communication service provider is developing various services such as different billing systems by time and location to secure more subscribers. Recently, services have been developed to differentially charge billing by specific regions, such as home-zone services. In the home-zone service, when each service subscriber designates a specific address (eg, home, work place, etc.) that he / she wants, the call charge is reduced for calls within the corresponding distance centered on the address (eg, wired call fee). ) As described above, a service control point (SCP) is added to the mobile communication system in order to perform intelligent network services such as a service for differentially charging each region and a prepaid service.

On the other hand, at present, it does not provide a service to differentiate the billing by region for prepaid service subscribers. Because, when a general subscriber performs an outgoing call to a predetermined prepaid service subscriber, the originating mobile exchange sends an AnalysisInformation message to the SCP performing the intelligent network service for driving the intelligent network incoming service. This is because SCP was not able to accurately charge because the incoming prepaid service subscriber could not know whether the incoming prepaid service subscriber is currently located in the designated territorial service area (eg, home-zone area).

Accordingly, an object of the present invention is to provide a method for allowing a prepaid service subscriber to receive a service for debiting a bill for each designated area.

Another object of the present invention is to provide a method of different billing according to the location of the incoming prepaid service subscriber in order for the prepaid service subscriber to receive the service to differentiate the billing for each designated area.

It is still another object of the present invention to provide a method of allowing a prepaid service subscriber to receive home-zone service, so that in the case of an outgoing and incoming call, a low rate can be paid according to the home-zone area.

In order to achieve the above object, the present invention provides a billing method for a prepaid subscriber in a mobile communication system, wherein the mobile switching center (MSC) receives a calling message including a called party's called party number from a calling subscriber at a mobile switching center (MSC). And determining a location of the prepaid subscriber based on a message including the location information of the prepaid subscriber in a service control point (SCP) managing billing information of the subscriber; In the case where the location of the prepaid subscriber is located in a pre-stored area, the method includes charging a call charge in the area to the calling subscriber.
According to an aspect of the present invention, a mobile communication system includes at least one of receiving a call message including a called party number of a prepaid subscriber from an originating subscriber to perform a call connection and periodically managing location information of subscribers in a management area. The mobile switching center (MSC) of the mobile station and the MSC managing location information of the subscribers, the message including the location information of the prepaid subscriber is checked and the area of the prepaid subscriber is located in the pre-stored area. Charge a call charge of the calling subscriber, if the location of the prepaid subscriber is outside the area, charge the call charge of the area to the calling subscriber, and charge a call charge other than the call charge of the area to the prepaid subscriber. Include a chargeable Service Control Point (SCP) And a gong.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Specific details appear in the following description, which is provided to aid a more general understanding of the present invention, and it should be understood by those skilled in the art that the present invention may be practiced without these specific details.

1 is a diagram illustrating an example of a configuration of a mobile communication system to which the present invention is applied, and FIG. 2 is a flowchart illustrating a method of charging a call to a prepaid service subscriber according to an embodiment of the present invention in a mobile communication system. . Hereinafter, a description will be given with reference to FIGS. 1 and 2.

The components of a mobile communication system can be largely divided into a base station and a mobile station. The base station controls a base station transmission system (Base Transmission System: BTS 115, BTS 150 in Figure 1) and a plurality of base station transmission system for performing a wireless connection between mobile stations and call mobility control associated with call processing. A base station controller (BSC 120, BSC 145 in FIG. 1) that performs (Call Mobility Management) may be divided. In addition, the mobile communication system may be a base station (e.g., BSC 120, BSC (e.g., BSC (120), BSC) between a public switched telephone network (PSTN) 175 and another communication network (not shown), such as a computer network. 145)) Mobile Switching Center (MS) (125, MSC 140) and the entire mobile communication system in charge of the transmission and reception path of the data and control signals between the lower network and the entire mobile communication system Base Station Manager (not shown.) May be included. That is, the MSC 125 and the MSC 140 are connected to a plurality of base stations (eg, BSC), and transmit / receive paths of call and user data between base station sub-networks of the same mobile carrier, and PSTN or the Internet. It is responsible for various data and control signal transmission / reception path between network and mobile station.

In addition, the visitor location registers (VLRs) 125 and 140 in the mobile communication system are provided to correspond to the mobile communication switching system such as MSC in a 1: 1 manner, and temporarily register subscriber information of the mobile wireless terminal. Save it. In addition, the VLRs 125 and 140 may be configured as main processors mounted in a mobile communication switching system, wherein the VLRs 125 and 140 search for subscriber numbers, subscribed services, and the home location register. The mobile radio terminal becomes the subject of an inquiry operation for various services registered with the mobile radio terminal (HLR) 135. SCP 130 has logic of intelligent network services such as prepaid service and service that charges the region differentially, and performs intelligent network call control.

Meanwhile, a general call setup procedure of the mobile communication system will be described with reference to FIG. 1. In this case, it is assumed that the mobile wireless terminal 110 is calling.

When the outgoing mobile wireless terminal 110 originates a call, the call setup request message is transmitted through the outgoing base transceiver system (BTS) 115 and the outgoing base station controller (BSC) 120. Mobile Switching Center (VLR) / Visitor Location Register (VLR) 125. The originating MSC / VLR 125 checks the Called Nuber provided in the message and transmits a Location Reguest message to the corresponding incoming Home Location Register (HLR) 135. The destination HLR 135 stores, as a database, phone numbers of registered mobile wireless terminals and information of subscribed services, and sends a Routing Request message to the destination MSC / VLR 140 based on the above information. Send.

The terminating MSC / VLR 140 then transmits a paging message via the terminating BSC 145 and the terminating BTS 150 to check the current state of the terminating mobile wireless terminal 155. If the terminating mobile radio terminal 155 is in a receivable state, the terminating MSC / VLR 140 transmits a corresponding Routing Request Return message to the terminating HLR 135. The incoming HLR 135 then sends a corresponding Location Request Return message to the originating MSC / VLR 125. At this time, if the incoming mobile wireless terminal 155 can receive, the Location Request Return message is provided with a Temporary Local DN (Drectory Number).

Then, the calling MSC / VLR 125 transmits the call set-up message to the called MSC / VLR 140 and the call is established. Then, the calling mobile terminal 110 and the called mobile terminal 155 are in a call state. do. At this time, a public switched telephone network (PSTN) (not shown) may exist between the originating MSC / VLR 125 and the destination MSC / VLR 140.

Hereinafter, referring to FIG. 1 and FIG. 2, a call charging method for a prepaid service subscriber according to an embodiment of the present invention will be described. The incoming mobile wireless terminal 155 is assumed to be subscribed to the intelligent network service.

 In step 205, when the call setup request message from the predetermined mobile subscriber is received, the originating MSC / VLR 125 checks the called number and routing number included in the message in step 210, and then the corresponding incoming HLR. Send a Location Reguest message to (Home Location Register) (135). In this case, the predetermined mobile subscriber may be a person subscribed to an intelligent network service or a person subscribed only to a general service.

When the incoming HLR 135 confirms that the routing number of the incoming phone number corresponds to the intelligent network service, the incoming HLR 135 recognizes that the set call is an intelligent network call in step 215 and corresponds to the originating MSC / VLR 125. Send a Location Request Return message. At this time, the corresponding Location Request Return message is provided with a number to be routed, called number and prepaid service call information. In step 220, the originating MSC / VLR 125 analyzes the information carried in the Location Request Return message and transmits an analyzed information message to the SCP 130 to perform the intelligent network call processing. The Analyzed Information message is a message for driving the intelligent network incoming service according to the present invention.

SCP 130 stores, on a per subscriber basis, areas where each prepaid service subscriber has registered to receive cheaper charges. The registration area may be the same as the area where the outgoing charge is to be cheaply received. The area may also be a home-zone service registration area. Upon receiving the Analyzed Information message, SCP 130 checks whether the current subscriber is actually located in the area where he registered to receive cheap charges according to the present invention.

In step 225, the SCP 130 transmits a Position Request message to the destination HLR 135, that is, the destination HLR 135 in which the destination intelligent network service subscriber is registered, in order to know the actual location of the destination prepaid service subscriber. At this time, the Position Request message includes the MSID, ESN, POSCODE. When the destination HLR 135 receives the position request message, the destination HLR 135 transmits a position request message to the corresponding destination MSC / VLR 140 in step 230.

Meanwhile, the MSC manages location information of mobile wireless terminals that are currently powered on for each base station and periodically perform power-on registration. In this case, the managed information may be MSC ID, SERVING CELL ID, SECTOR ID, RTD information, and the like. Location information management operations of the mobile wireless terminals are those that can be provided from the configuration of a mobile communication system capable of a location tracking service, a detailed description thereof will be omitted.

That is, when the called MSC / VLR 140 receives the Position Request message in step 230, the called MSC / VLR 140 transmits a paging message to the called mobile radio terminal 155 to check the current state of the terminal. If the incoming mobile radio terminal 155 is in a receivable state, the incoming MSC / VLR 140 may perform an MS ID, an MS STATE, an MSC ID, a serving cell ID, a SECTOR ID, RTD information, that is, an incoming mobile radio terminal in step 235. The current position information of 155 is transmitted to the incoming HLR 135. In step 240, the incoming HLR 135 transmits the current location information of the incoming mobile wireless terminal 155 to the SCP 130.

The SCP 130 compares the current location information of the received terminating mobile terminal 155 with a location registered by a subscriber of the terminating mobile wireless terminal 155 to receive an inexpensive charge. SCP 130 then determines whether the incoming prepaid service subscriber is currently in the location where he or she is registered or in an area other than the location where he or she is registered. The SCP 130 transmits an analyzed information return message to the originating MSC / VLR 125 in step 245.

The originating MSC / VLR 125 receiving the message establishes a call with the terminating mobile wireless terminal 155 by performing a general call connection procedure. As a result, in step 250, the calling party and the called party perform a call. At the end of the call, in step 255, the originating MSC / VLR 125 transmits the charging information to the SCP 130. The billing information may be a talked time. SCP 130 then charges the outgoing subscriber at a low call rate if the incoming prepaid subscriber made a call in the region where he or she registered, and prepaid the incoming subscriber if the call was made outside of the region registered by the incoming prepaid subscriber. Charge the discounted call rate of the subscriber and charge the additional call charges other than the discounted call to the incoming prepaid subscriber.

On the other hand, FIG. 2 is a case where the mobile subscriber makes a call, for example. However, even when the wired subscriber 160 of FIG. 1 makes a call, the present invention can be applied. That is, the operations from step 220 to step 250 of FIG. 2 are the same.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, the present invention provides a prepaid prepaid service by varying the billing according to the location of the prepaid prepaid service subscriber so that the prepaid service subscriber can receive a service (eg, home-zone service) that differentiates the billing for each designated area. Subscribers can pay low fees by applying different billing charges depending on their location in the designated area, rather than paying the same high call rate regardless of the region. In addition, the operator can attract more subscribers, resulting in increased profits.
