Description

One phone service system and its method {System and method for onephone service}

The present invention relates to a one-phone service system and a method thereof, and more particularly, to distinguish incoming calls of a plurality of one-phone service subscribers using the same single voice line of a public switched telephone network (PSTN), or to voice over VoDSL. The present invention relates to a one-phone service system and a method for providing an incoming / outgoing service simultaneously to a plurality of one-phone service subscribers using a single voice line of a PSTN using DSL) technology.

Onephone is a telephone terminal that can be used as a wired telephone terminal and can also be used as a mobile telephone terminal depending on the time and place by having the functions of a landline telephone and a mobile telephone at the same time.

One-phone service is a wired / wireless integrated service that allows one-phone to receive telephone service through a PSTN to a landline telephone number indoors and to a mobile telephone number outdoors.

That is, the one-phone service is a service that allows a user to make a call using both a PSTN and a mobile telephone network.

To this end, one phone is equipped with dual mode functions of Bluetooth and Code-Division Multiple Access (CDMA), and uses Bluetooth mode when using a PSTN and CDMA mode when using a mobile phone network.

In addition, when using a wired telephone service using the PSTN in the Bluetooth mode, a Bluetooth Access Point (AP) is installed indoors to connect the one phone to the PSTN.

When the subscriber is located indoors, the Bluetooth AP recognizes the presence of the subscriber and informs the intelligent network server of providing the one-phone service.

If the caller makes a call to the subscriber using the subscriber's landline phone number, the intelligent network server checks the subscriber's location and connects the call through the Bluetooth AP through the PSTN if the subscriber's location is indoors and the mobile telephone network if the subscriber's location is outdoors. Connect a call through.

When the caller makes a call to the subscriber using the subscriber's mobile phone number, the caller connects the call directly to the subscriber through the mobile telephone network as in the general mobile telephone service.

However, if multiple subscribers are located in the same room, the multiple subscribers all use the same single voice line of the PSTN, so the intelligent network server can determine which of the subscribers the call originated from the landline phone number. It will not be distinguished and will be delivered to all subscribers.

This may not only provide a wrong service by connecting a call call with a subscriber that the caller does not want, but there is a problem that multiple subscribers cannot simultaneously make calls over the same single voice line even when multiple subscribers receive.

In order to solve the above problems, an object of the present invention is to connect a call call by distinguishing a plurality of one-phone service subscribers located in the same room.

An object of the present invention is to allow multiple one-phone service subscribers to receive and make calls simultaneously through the same single voice line of the PSTN.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows an embodiment of a one-phone service system according to the present invention, which includes a Bluetooth AP 10 supporting multiple signals and an intelligent network server 20 for distinguishing subscriber incoming calls by assigning unique numbers for each subscriber. One phone service system.

Subscriber A (50) and Subscriber B (60) are subscribers using the same landline telephone number and are provided with one-phone service using a single voice line of the Bluetooth AP 10 and the PSTN 30 installed indoors. admit.

The one-phone service system according to an embodiment of the present invention assigns a unique number to each subscriber in order to distinguish between subscriber A 50 and subscriber B 60 using the same single line of the PSTN 30. 70) allow each subscriber to dial a unique number.

That is, the unique number itself for distinguishing the subscriber becomes the telephone number to enable the caller 70 to call the subscriber, and the subscriber can use this unique number as a lifetime number that can represent himself.

In addition, the unique number may be provided by grouping by subscribers using the same voice line of the PSTN 30 in such a way as to change only the end digit.

Due to this unique number, the intelligent network server 20 distinguishes each subscriber as a unique number given to each subscriber when a large number of subscribers are registered in the same room.

In addition, the Bluetooth AP 10 supports multiple signals and distinguishes and transmits all signals of the subscriber A 50 and the subscriber B 60.

When the subscriber is located indoors, the Bluetooth AP 10 registers the subscriber's location to the intelligent network server 20 by interworking with the subscriber's Bluetooth mode, and when the caller 70 calls the subscriber's unique number, the PSTN 30 To make a call.

When the subscriber is located outdoors, the subscriber's location is registered in the intelligent network server 20 by the CDMA mode of the one phone. When the caller 70 dials the subscriber's unique number, the subscriber makes a call through the mobile telephone network 40. .

Or, if the location of the subscriber is not registered indoors by the Bluetooth AP 10, it determines that the subscriber is located outdoors, and connects the call call generated through the mobile telephone network 40.

2 shows a process of distinguishing incoming calls to multiple subscribers in the same room by this configuration.

First, since both the subscriber A 50 and the subscriber B 60 are indoors, the Bluetooth AP 10 registers the positions of the subscriber A 50 and the subscriber B 60 with the intelligent network server 20.

When the caller 70 makes a call to the unique number of the subscriber A 50 (S210), the intelligent network server 20 checks the location of the subscriber A 50 (S220) and determines whether it is located indoors (S230). .

When the subscriber A 50 is located indoors, the call is transferred to the one-phone of the subscriber A 50 via the Bluetooth AP 10 using the PSTN 30 (S240), and the subscriber A 50 is located indoors. If not, the call is transferred to the one-phone of the subscriber A 50 using the mobile telephone network 40 (S270).

At this time, since both the subscriber A 50 and the subscriber B 60 are indoors, the subscriber B 60 may already be making a call using the PSTN 30.

Thus, if the voice line of the PSTN 30 is busy (S250), the call is transferred to the mobile telephone network 40 to transfer the call to the subscriber A 50 using the mobile telephone network 40 (S270).

That is, even though the subscriber A 50 is located indoors, since the subscriber B 60 already uses the voice line of the PSTN 30, the subscriber A 50 uses the mobile telephone network 40 to make a call using a one-phone.

However, if the voice line of the PSTN (30) is not busy (S250), subscriber A (50) is a call call is connected to the caller 70 and the PSTN (30) can make a call (S260).

As described above, an embodiment according to the present invention distinguishes a called terminal by assigning a unique number to each of a plurality of one-phone service subscribers using a single voice line of a PSTN.

3 shows another embodiment of a one-phone service system according to the present invention, a Bluetooth AP 310 supporting multiple signals, a VoDSL concentrator 320 for packetizing multiple voices and transmitting them on one voice line; One phone having a VoDSL gateway 330 for restoring the packetized voice transmitted from the VoDSL concentrator 320 to the PSTN 340, and an intelligent network server 350 for assigning subscriber-specific numbers to distinguish subscribers. Service system.

Subscriber A 380 and Subscriber B 390 are subscribers using the same landline telephone number, and the one-phone service system according to another embodiment of the present invention allows these multiple subscribers to simultaneously talk on a single voice line of the PSTN 340. Use VoDSL technology to make it possible.

Accordingly, the VoDSL concentrator 320 packetizes and transmits a plurality of voices inputted from a plurality of subscribers, and the VoDSL gateway 390 recovers it and delivers it to the PSTN 340 to make a call with the called / caller 370. Let's do it.

In addition, in order to distinguish between subscriber A 380 and subscriber B 390 using the same single line of PSTN 340, a unique number is assigned to each subscriber, and the caller 370 is assigned a unique number of each subscriber. Let the call go.

That is, the unique number itself for distinguishing the subscriber becomes a phone number to enable the caller 370 to call the subscriber, and the subscriber can use this unique number as a lifetime number that can represent himself.

In addition, the unique number may be provided by grouping by subscribers using the same voice line of the PSTN 340 in such a way as to change only the end digit.

Due to this unique number, the intelligent network server 350 distinguishes each subscriber as a unique number given to each subscriber when a large number of subscribers are registered in the same room.

In addition, the Bluetooth AP 310 supports multiple signals and distinguishes and transmits all signals of the subscriber A 380 and the subscriber B 390. If the subscriber is located indoors, the Bluetooth AP 310 interworks with the Bluetooth mode of the subscriber one phone to locate the subscriber. Register with the intelligent network server (350).

The Bluetooth AP 310 may be implemented integrated with the VoDSL concentrator 320.

4 shows a process in which a plurality of subscribers in the same room make a call at the same time by this configuration.

First, since both subscriber A 380 and subscriber B 390 are indoors, the Bluetooth AP 310 registers the locations of subscriber A 380 and subscriber B 390 with the intelligent network server 350.

When the caller 370 makes a call to the unique number of the subscriber A 380 (S410), the intelligent network server 350 checks the location of the subscriber A 380 (S420) and determines whether it is located indoors (S430). .

When the subscriber A 380 is located indoors, the call is transferred to the one-phone of the subscriber A 380 via the VoDSL gateway 330, the VoDSL concentrator 320, and the Bluetooth AP 310 using the PSTN 340. (S440).

When subscriber A 380 receives the call, the subscriber A 380 makes a call (S450).

At this time, since both subscriber A 380 and subscriber B 390 are indoors, subscriber B 390 may already be making a call using a single voice line of PSTN 340.

However, since the one-phone service system of another embodiment according to the present invention uses VoDSL technology, multiple subscribers can simultaneously make calls on the same single voice line of the PSTN 340.

Thus, even when the voice line of the PSTN 340 is busy, the call is delivered to the subscriber A 380 using the PSTN 340 without the need to divert the call to the mobile telephone network 360.

The above-described process is a process of connecting a call when the caller 370 makes a call to the subscriber A 380 or the subscriber B 390, but on the contrary, the subscriber A 380 or the subscriber B 390 sends the called party 370 If you try to make a call with), it is used in the same way as connecting a call.

That is, when subscriber A 380 makes a call to the called party 370 (S410), the intelligent network server 350 checks whether subscriber A 380 is located indoors (S420), and when it is located indoors (S430), the PSTN Using 340 (S440) connects the call to the called party 370 (S450).

At this time, even if subscriber B 390 is already using the line of PSTN 340, the call call of subscriber A 380 may be connected.

If the subscriber is located outdoors, the subscriber's location is registered in the intelligent network server 350 by the CDMA mode of the one phone, and the subscriber makes a call through the mobile telephone network 360 with the called / caller 370.

Alternatively, if the location of the subscriber is not registered indoor by the Bluetooth AP 310, the subscriber determines that the subscriber is located outdoors and connects the call call generated through the mobile telephone network 360.

As described above, another embodiment according to the present invention distinguishes a called terminal by assigning a unique number to each of a plurality of one-phone service subscribers using a single voice line of the PSTN, and uses a VoDSL technique to establish a single voice line of the PSTN. This allows multiple subscribers to talk simultaneously.

As described above, the present invention can provide a personalized incoming service using a single voice line by assigning a unique number to a plurality of one-phone service subscribers using a single voice line to distinguish a called terminal. The height is effective.

In addition, by enabling simultaneous calls to the same voice line using VoDSL technology, it is possible to efficiently utilize a limited voice line, and provide a convenient and economical communication means using multiple calls and unique numbers.
