The SSP sends the one-phone identifier to an SCP of the intelligent network(S520). The SCP retrieves a wired telephone number corresponding to the one-phone identifier(S530). When an accounting target is determined, the SCP indicates a call setup with the receiver number while making the call with a receiver(S540,S550).

Description

Charging method and system for one-phone service

The present invention relates to a charging method and a charging system for a one-phone service supporting a wireless telephone using a mobile communication mode and Bluetooth in one terminal. More specifically, the present invention relates to a method and system for collectively managing charges generated during Bluetooth communication using a fixed Bluetooth access point installed in a home and a floating Bluetooth access point installed in a public place or business.

Bluetooth is a technical specification for wireless connectivity (2.4GHz ISM Open Band) within short range (10m to 100m) of small, low cost, low power consumption portable devices such as mobile phones, portable PCs, network access points, and other peripheral devices. It is a technology that is in the spotlight as a local area network.

Bluetooth adopts a wireless LAN transmission method using the 2.4GHz band of ISM (Industrial, Scientific, Medical) band. The 80MHz wide frequency is commonly assigned to this band worldwide, making it free for anyone to use without government approval. This band suppresses mutual interference by limiting the size of the transmission output to 100mW or 1mW so that multiple users can share it. The basis of Bluetooth is packet communication, but both data and voice communication are possible. By connecting two devices one-to-one, one-way data transfer can be up to 721kbps. In Bluetooth, up to eight devices come together to form a single network called a piconet, which allocates the entire capacity as appropriate between devices.

In addition, several independent piconets can be overlapped in the same space, so that they can be applied to places with high density of information processing and communication devices. Other features include transmission error correction, identity verification, passwords and power saving features.

Due to the advantages of the above-mentioned Bluetooth, the leading field of the application of Bluetooth is the application of the mobile phone. Among these applications, there are one-phone (two in one-phone or three in one-phone) which can use mobile communication and wireless telephone using a wired network, and Ericsson, Nokia, etc. have already produced the one-phone terminal. The one phone integrates the CDMA module and the Bluetooth module into one terminal, and the Bluetooth module performs Bluetooth communication with a Bluetooth access point, which is a connection point of an external network such as a PSTN or an XDSL. Therefore, the one-phone user can make a call by making a call using a wired network in the Bluetooth area, thereby making it possible to make a call at a low rate while ensuring its mobility.

1 is a schematic diagram illustrating an entire system for the aforementioned one-phone service.

The one-phone terminal 100 having the CDMA mobile communication and the Bluetooth function can be used as a normal mobile communication terminal outside the Bluetooth region 10. When the Bluetooth terminal 100 enters the Bluetooth region 100, it is automatically or manually switched to the Bluetooth mode. To perform wireless communication with the Bluetooth access point 200. At this time, the outgoing call of the one-phone terminal 100 is directed to the wired network 30 through the Bluetooth access point 200. The call is transmitted to the called party 60 through the wired network 30 or the mobile telephone network 40 according to the called party's environment. In addition, it is possible to use a variety of additional services using the intelligent network 50 according to the designation of the sender and the called party.

That is, the Bluetooth mode of the one-phone service performs the same operation as using a normal wired network except for performing Bluetooth communication between the Bluetooth access point and the one-phone. Accordingly, the charge of the wired telephone network can be applied.

On the other hand, there are two types of Bluetooth access point (hereinafter, referred to as one-phone access point) for one-phone service. The first type of fixed mode is a method of simply receiving a counterpart phone number from a one-phone terminal and requesting a call setup to the phone number. This method is suitable for home or company internal one-phone access point that the one-phone access point directly corresponds to the wired subscriber network. The second type of floating mode is a type in which a one-phone access point is placed in an arbitrary place such as a public place or a business, and anyone can use wired communication using Bluetooth within the coverage of the one-phone access point.

In the above-described fixed mode, the use of a wired telephone using Bluetooth may be charged to a subscriber corresponding to a one-phone access point. In the floating mode, however, the billing target becomes a user of the one-phone terminal. Cannot be performed.

That is, an operator providing a one-phone access point in a floating mode should charge a fee appropriately for a user who uses the one-phone service. However, if an unnecessary fee settlement step is imposed on the user, the one-phone service has the mobility of the mobile terminal. Rather, there is a problem that results in harm.

In addition, there is a problem in that, if the network provider providing a service does not manage the royalty fee management of the wired telephone, the unnecessary cost for the service construction is consumed and the reliability of billing cannot be secured to the user.

The present invention is to solve the above-described problems of the prior art, and provides a one-phone service billing method and system for performing unified charging in a fixed mode as well as a floating mode one-phone access point. In more detail, the present invention provides a system and method for billing by adding the one-phone service fee to a pre-owned wired telephone fee by using the identifier of the one-phone terminal and the intelligent network service.

DETAILED DESCRIPTION A system and method according to an embodiment of the present invention will now be described in detail with reference to the drawings.

2 shows a system of one-phone service according to an embodiment of the present invention.

According to an embodiment of the present invention, a one-phone system includes a plurality of one-phone access points 201 and 202 including both a fixed mode and a floating mode, local switches 31 and 32, and a service switching point. SSP) 500 and an intelligent network switch including a service control point (hereinafter referred to as SCP) and a billing DB 700. In addition, the system of the present invention may include a wired network 30 and a gateway connecting the wireless network 40.

Hereinafter, the operation of the components of the system according to an embodiment of the present invention will be described in detail. In the embodiment of the present invention, it is assumed that the Bluetooth area 10 is an area of the fixed mode one-phone access point 201, and the Bluetooth area 12 is an area of the floating mode one-phone access point 202. The one-phone terminal 100 may use the one-phone terminal 100 as a home wireless telephone using the wired network 30 in the Bluetooth area using the fixed mode one-phone access point 201. At this time, since the fixed mode one-phone access point 201 is physically installed inside or outside the home wireless telephone, the call is sent like a normal landline telephone, and the billing is also made to the subscriber's telephone number.

Meanwhile, when the same one-phone terminal 100 switches to the wired call mode using the one-phone access point 202 in the floating mode, the one-phone terminal detects that the access point 202 is in the floating mode and changes the Bluetooth communication mode. Register the floating mode access point 202. When the call origination is performed using the floating mode one-phone access point 202, a one-phone identifier such as a mobile communication number or a device serial number of the one-phone 100 is transmitted. In order to use the floating mode, the billing wireline number corresponding to the one-phone identifier is registered in advance with the wireline network operator. Since the one-phone service that can use the floating mode access point is likely to use the fixed mode access point, it is not difficult to map the wired telephone number corresponding to the one-phone identifier.

The SSP 500 of the intelligent network grasps the identifier of the access point transmitted from the one-phone access point and the one-phone identifier, and requests the billing service to the SCP 600. SSPs in intelligent networks have the ability to detect intelligent network services and communicate with SCPs. SCP in intelligent network has service logic program and data necessary for intelligent network service processing and is connected to SSP through signaling network.

When the SSP 500 requests the billing service, the SCP 600 extracts the one-phone identifier transmitted together, searches for the stored landline telephone number corresponding to the one-phone identifier, and charges the corresponding landline telephone number. When the SCP 600 performs the charging service, the SCP 600 commands the SSP 500 to set up a call.

3 is a block diagram showing the configuration of a one-phone and one-phone access point according to an embodiment of the present invention.

One phone 100 of the present invention includes a Bluetooth module 120 for performing Bluetooth communication, a CDMA module 130 for performing code division multiple access mobile communication, a mode switching unit 110 for switching the two communication modes, And a one phone identifier 140 corresponding to each one phone. When the Bluetooth mode is set manually or automatically by the mode switching unit 110, the one phone communicates with the one phone access point 200.

The one-phone access point 200 is a wired call processing unit 210 for performing a normal wired call via the one-phone 100 and Bluetooth communication, and an access point mode switching unit 220 for setting a fixed mode or a floating mode. It includes. According to the mode setting of the one-phone access point 200, it is determined whether to transmit the one-phone identifier when calling. The access point of the floating mode transmits an access point identifier informing the intelligent network of the floating mode.

4 is a block diagram illustrating an intelligent network according to an embodiment of the present invention.

The intelligent network according to the embodiment of the present invention largely includes the SSP 500, the SCP 600, and the charging DB 700. The SSP 500 includes an access point identifier detection unit 510 for detecting an access point identifier transmitted from the one-phone access point 200 and a call processing unit for performing call processing independently or by a command of the SCP 600. . The SCP 600 detects the one-phone identification number from the outgoing signal and searches the corresponding landline telephone number. The one-phone identifier determination unit 610 and the billing information table 620 to which the landline telephone number corresponding to the one-phone identification number are mapped are mapped. And a service control unit 630 for controlling the determination and search function and instructing call processing. The billing database 700 may be installed inside or outside the intelligent network, and stores billing details in a corresponding wired telephone number.

Hereinafter, the operation between the components of the above-described system will be described in detail along with the signal flow.

5 illustrates a signal flow when using a floating mode one-phone access point according to an embodiment of the present invention.

When the one-phone user 100 attempts to make a call in the floating mode one-phone access point, the one-phone 100 requests a call origination with the one-phone identifier to the one-phone access point 200 (S10).

Since the one-phone access point 200 operates in a floating mode, the one-phone access point 200 transmits an access point identifier that may indicate the floating mode, an identifier of the one-phone requesting a call connection, and a telephone number of the other party to the intelligent network (S20). The identifier of the access point may indicate that the current access point is set to the floating mode. If the access point is already registered with the service network in the floating mode when installing the access point, only the device serial number may be transmitted. Such modifications of construction are apparent to those skilled in the art.

SSP 500 of the intelligent network recognizes the floating mode through the access point identifier, and transmits the one-phone identifier to the SCP (S30). SCP 600 of the intelligent network detects the wire telephone number corresponding to the one-phone identifier, and instructs the SSP 500 to process the call (S40).

Then, the SSP 500 requests a call setup to the called party corresponding to the other party's phone number (S50), and when the call is received (S60).

When the call is terminated, the SCP 600 charges the charge corresponding to the talk time to the wired telephone number corresponding to the one-phone identifier, and stores it in the charge DB 700 (S70).

6 is a flowchart illustrating a charging method of a one-phone service according to an exemplary embodiment of the present invention.

In step S100, the user attempts to make a one-phone call in the Bluetooth mode and inputs a receiver number (S200). When the one-phone call of the one-phone Bluetooth mode is attempted, the one-phone transmits the one-phone identifier and the receiver phone number to the one-phone access point (S300).

Once the call is requested, the one-phone access point operates in two ways depending on the setting mode (S400). In the fixed mode, the call is requested by the receiver number through the wired network corresponding to the one-phone access point, and the call is performed (S610 and S620).

When the access point is in the floating mode, the receiver number, the one-phone identifier, and the AP identifier are transmitted to the SSP of the intelligent network (S510). If it is recognized that the SSP is in the floating mode through the AP identifier, the SSP transmits the one-phone identifier to the SCP of the intelligent network (S520).

In step S530, SCP searches for a landline telephone number corresponding to the one-phone identifier. The landline number is a billing number to be billed in the one-phone call (S530).

When the billing target of the one-phone call is determined, the SCP instructs the SSP to set the call to the recipient number and the user performs a call with the called party. (S540, S550)

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.

According to the above-described configuration of the present invention, the one-phone user can use the one-phone service without a separate settlement procedure and receive a reasonable charge when making a call in a floating one-phone access point other than the fixed mode access point installed in his home. In addition, even in one-phone service companies, the billing management is easy by using a unified billing system, and a separate facility for exchanging information with other network operators is required for the billing management, thereby reducing the cost.
