Includes all wireless environments that support mobile communication technology.

The mobile communication network 200 is involved in call setup and resource allocation of mobile client groups 100/1 to 100 / N. Although not shown in the drawing, the mobile communication network 200 is involved in call setup and resource allocation of a second, different mobile client group. A mobile communication network may be established, and may include a CS (Circuit Service) domain in case of synchronous and a PS (Packet Service) domain in case of asynchronous.

The mobile communication network 200 assures mobility of the mobile client group 100/1 to 100 / N, and performs handover and radio resource management functions. The mobile communication network 200 includes base stations 202/1 to 202 / N, 204/1 to 204 / N, and base station controllers 206/1 to 206 / N, and supports both synchronous and asynchronous. Here, in the case of synchronous, the base stations 202/1 to 202 / N and 204/1 to 204 / N are base transceiver stations (BTSs), and the base station controllers 206/1 to 206 / N are base station controllers (BSCs). In the asynchronous case, the base stations 202/1 to 202 / N and 204/1 to 204 / N are RTS (Radio Transceiver Subsystem), and the base station controllers 206/1 to 206 / N are RNC (Radio Network). Controller). Of course, the mobile communication network 200 is not limited thereto, and may include a GSM network other than a CDMA network and an access network of all mobile communication systems to be implemented in the future.

The base stations 202/1 to 202 / N and 204/1 to 204 / N having such an example configuration receive a call attempt message from the mobile client group 100/1 to 100 / N through the traffic channel among the signal channels. Receive and transmit the received call attempt message to the base station controllers 206/1 to 206 / N. In addition, the base stations 202/1 to 202 / N and 204/1 to 204 / N perform baseband signal processing, wired / wireless conversion, and transmission and reception of wireless signals, and the like.

The exchange 208 is an Access Switching Subsystem (ASS) that performs distributed call processing, an Interconnection Network Subsystem (INS) that performs centralized call processing, and a Central Control Subsystem (CCS) that centralizes operation and maintenance. ), A subsystem such as a Location Registration Subsystem (RLS) that performs storage and management of information for mobile subscribers.

The prepaid subscriber service server 102 attracts prepaid subscribers and moves information such as prepaid free points when a client requests a prepaid call service by accessing a homepage providing a prepaid call service through the Internet (not shown). It is a device provided to the communication network (200).

The SDP 104 manages a prepaid call service account and earned points, and provides an interworking function with a prepaid subscriber gateway (Gateway), not shown. The SDP 104 performs an automatic deactivation (prepaid call service stop) function when the prepaid call point is exhausted.

SCP 106 is a service controller that manages the logic and data of the intelligent network service, and controls all processes for the intelligent network service. SCP 106 also interworks with other network resources using SS7 (Signaling System 7) -based and IP-based intelligent network standard protocols (INAP, WIN, CAMEL). At this time, the SCP 106 can check the availability of the prepaid call and the available time (whether the point is used) through the SDP 104 upon the request from the mobile client.

The supplementary service network 108 is a network supporting the SS7 or No.7 protocol, and provides mobile clients with various supplementary services, for example, an intelligent network service including an incoming billing service, a virtual private network service, and the like. SS7 is a type of intelligent network protocol designed to provide a specific service in the 80's voice network, and is a protocol for collectively managing call information and data communication access information. Its primary function is to provide transactional capabilities to perform fast call setup and remote database reference operations. It also features out-of-band signaling (OOB) to support call setup, billing, and call routing. It performs a function of bridging between the packet data communication network (PDSN) and the PSTN by performing an information exchange function. SS7 manages meta information of both voice communication and data communication, whereas No.7 protocol used in general intelligent network manages meta information of voice communication call. Based on the integrated environment of data communication, various intelligent network systems can be developed. In particular, SS7 is very important in applications such as call routing, area code portability, prepaid and postpaid calling cards, and IP phones. At present, voice communication network is SS7 integrated operation and is adopted as essential interworking signaling method for VoIP, UMS, intelligent network. SS7 is characterized by high-speed packet switching, out-of-band signal processing using SSP (Service Switching Point), STP (Signal Transfer Point), SCP, and the like.

The HLR 110 is a database that manages the information of the registered mobile communication terminal, voice and packet information, and includes user information of the mobile client group 100/1 to 100 / N, mobile identification number (MIN) information (synchronous), International Mobile Subscriber Identity (IMSI) information (asynchronous), routing information, and the like are stored.

2 is a flowchart illustrating a prepaid call service process in a conventional mobile communication network.

As shown in FIG. 2, in step S200, the prepaid subscriber service server 102 determines whether a person or a corporation accesses the corresponding homepage and requests a free call point transmission within a reserve range.

When the free call point transmission is requested, the prepaid subscriber service server 102 proceeds to step S202 and transmits the free call point to the SDP 104 through a gateway (not shown). The SDP 104 accumulates the free call point in a free call account of any mobile client, for example, mobile client 1 (100/1). The free call point earning at this time can be equally earned not only on the mobile client but also on the client's free call account on the Internet.

On the other hand, the exchange 208 of the mobile communication network 200 determines whether the call origination is attempted by the mobile client 1 (100/1) (S204), if the call origination is attempted to proceed to step (S206).

In step S206, the exchange 208 requests the call origination to the HLR 110 and transmits the SCP routing station number.

The exchange 208 then inquires SCP 106 of the availability of free calls and the available time, as in step S208. In other words, the use of free call points is confirmed through SCP (106).

When the availability of free calls and available time is confirmed through SCP 106, the exchange 208 proceeds to step S210 to allow the transmission of the mobile client 1 (100/1) by the time allowed for the call.

Thereafter, it is determined whether the call of the mobile client 1 (100/1) is terminated (S212), and when the call of the mobile client 1 (100/1) is terminated, the exchange 208 proceeds to step S214, and SCP 106 is performed. Notify the usage time (talk time). When the use time (talk time) is notified to the SCP 106, the SCP 106 provides the corresponding use time information to the SDP 104, and the SDP 104 moves as much as the use time of the client 1 (100/1). Deducts free call points.

As described above, the prepaid call service through the conventional mobile communication network can use the free mobile phone call service using various mileage points on the Internet.

However, in the existing prepaid call service through the mobile communication network, it may be difficult to determine whether the prepaid call service is registered according to the subject of registration.

That is, when an individual registers a prepaid call service, the individual can easily recognize that he or she is subscribed to the prepaid call service except for a mistake. When a corporation managing the homepage is registered through a questionnaire or other questionnaire and an individual manages the homepage, the individual may not be aware of whether or not to register the prepaid call service.

In this case, when the prepaid subscriber attempts a "normal call" without knowing that he (the prepaid subscriber) is registered in the prepaid call service, the exchange will automatically activate a prepaid call feature code, e.g. 1587PFX ( Prefix) will be inserted to link to "no number" or "other corporate customer center or ARS." Therefore, the subscriber who is registered in the prepaid call service but does not recognize the fact, there is a problem that the service complaints will inevitably increase.

Accordingly, the present invention, when registering a prepaid call service by an individual or a corporation (including wired and wireless) by notifying the mobile client whether or not to register the prepaid call in the mobile communication network that can eliminate the incomplete call in advance by easy recognition It is intended to provide a service system and method.

In addition, the present invention, the prepaid call service system in the mobile communication network that can increase the service satisfaction by notifying the mobile client to easily recognize when the point of the subscriber (including wired / wireless) for the prepaid call is exhausted And to provide a method.

According to an aspect of the present invention, there is provided a prepaid call service system in a mobile communication network, comprising: a mobile client group that provides a wireless communication service to a subscriber by interfacing with the mobile communication network through a wireless connection, and within the mobile client group.
