Abstract

The present invention relates to a multiple call method and system for a one-phone terminal which can selectively use a mobile communication network and a wired network using Bluetooth.

In the multi-call method of the present invention, when the wired network performs an incoming / outgoing call in a state occupied by another one-phone terminal, the Bluetooth access point notifies the one-phone terminal of the line occupancy state and inquires about the line switching. When the one-phone terminal receives the line switching inquiry, the one-phone terminal user performs the call using the mobile communication network or the VoIP communication network.

Description

Method for allowing multiple of users to be specked by one-phone terminals and system therof}

The present invention relates to a data service billing method of a one-phone terminal which can selectively use a wired network using mobile communication and Bluetooth. More specifically, the present invention relates to a charging method when a one-phone terminal uses a data service within Bluetooth coverage.

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 signal 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.

However, in the case of a conventional one phone, when one user is in a call when a plurality of users are connected in a Bluetooth mode, other users cannot make calls through the wired network, and incoming calls are not possible, so that an individual communication function such as a mobile communication terminal is possible. There was a problem that hurts.

That is, the one-phone has a problem that the function is limited when the individual incoming and outgoing function supported in the mobile communication mode is occupied by the line of the wired telephone network in the Bluetooth mode.

In order to solve the problems of the prior art, an object of the present invention is to provide circuit switching for individual incoming / outgoing calls of one phone, and to provide a secure multiple lines. More specifically, the present invention provides a method in which a plurality of users can make a call using another communication network even when a line of a wired telephone network is occupied in a Bluetooth mode.

In order to solve the above technical problem, a method of transmitting a plurality of one-phone terminal according to a feature of the present invention is:

(a) performing a transmission attempt using a first communication network by a one-phone terminal in a Bluetooth mode;

(b) determining, by the Bluetooth access point, whether the line of the first communication network is occupied;

(c) if the line of the first communication network is in an occupied state, requesting a Bluetooth access point to switch the line to the second communication network from the one-phone terminal; And

(d) the one-phone terminal performing a circuit switching to the second communication network in response to a circuit switching request.

In addition, the multiple one-phone terminal call system according to a feature of the present invention,

A mobile communication module supporting a mobile communication function; A Bluetooth module supporting a Bluetooth communication function; A mode switching unit for switching the two modes; And a line searching unit for searching for a line occupancy state and controlling the mode switching unit according to a search result;

A Bluetooth module for performing Bluetooth communication with the one-phone terminal; A wired network connection unit having an external wired network and an interface function; A line occupancy detector for determining a line occupation of the wired network; And a Bluetooth access point including a line state notification unit for transmitting the determination result of the line occupation detection unit to the one-phone terminal through the Bluetooth module.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention. Like parts are designated by like reference numerals throughout the specification.

Now, a multi-call method and system of a one-phone terminal according to an embodiment of the present invention will be described in detail with reference to the drawings.

2 is a block diagram showing the configuration of a one-phone terminal according to an embodiment of the present invention.

In an embodiment of the present invention, the one-phone terminal 100 includes a CDMA module 110, a Bluetooth module 120, a mode switching unit 130, and a line searching unit 140. The Bluetooth module 120 includes a wireless telephone communication processor 121 capable of using a one-phone terminal as a wireless telephone through a wired network, and a VoIP communication processor supporting functions of a VoIP (Voice over Internet Protocol) communication terminal.

When the one-phone terminal 100 exists outside the Bluetooth coverage, the one-phone terminal 100 performs a call using the mobile communication network through the CDMA module 110. On the other hand, when the one-phone terminal 100 falls within the Bluetooth coverage, the one-phone terminal 100 connects to the Bluetooth access point using the Bluetooth module 120. The Bluetooth access point connects to a wired network such as a PSTN or xDSL, and relays communication with the one-phone terminal.

In order to switch the communication mode described above, the one-phone terminal 100 includes a mode switching unit 130. In the embodiment of the present invention, the mode switching unit 130 may also be controlled by the line searching unit 140.

The line searching unit 140 searches for occupying the wired network line in the Bluetooth communication mode. The line search unit 140 determines whether a wired telephone network is currently occupied by another terminal through communication with a Bluetooth access point.

If the wired telephone network is occupied by another terminal, when there is a request for origination and reception of the one-phone terminal 100, the line search unit 140 controls the mode switching unit 130 to perform another communication mode. In order to activate (CDMA communication mode or VoIP communication mode), the CDMA module 110 or the VoIP communication processing unit 122 is activated.

Here, the line retrieval unit 140 may retrieve the line occupancy state and display the line occupation in the form of a message when there is a call request, and the mode switching unit 130 may change the communication mode by a user's operation.

Therefore, the one-phone terminal according to the embodiment of the present invention can automatically perform incoming / outgoing calls using another communication mode even when the line of the wired telephone network is occupied.

3 is a block diagram illustrating a configuration of a Bluetooth access point according to an embodiment of the present invention.

The Bluetooth access point 200 according to the embodiment of the present invention includes a Bluetooth module 210, a PSTN connection unit 220, an xDSL connection unit 230, a line state notification unit 240, and a line occupation detection unit 250. .

The line occupation detecting unit 350 is connected to the PSTN connection unit 220 and the xDSL connection unit 230 to determine a line occupation state. For example, a busy tone may be detected from the PSTN, or an IP address allocation state may be detected by the Bluetooth access point to detect a line state of a wired communication network connected to the Bluetooth access point 200.

The line occupation detection result is transmitted to the one-phone terminal 100 via the Bluetooth module 210 and the line state notification unit 240.

The line occupancy state information may be broadcasted to a one-phone terminal within Bluetooth coverage, or may be notified in a message form when an incoming / outgoing request is made.

4 is a flowchart illustrating a method of providing multiple currencies according to an embodiment of the present invention.

In step S100, the one-phone terminal existing in the Bluetooth coverage attempts to make a call using a wired telephone network via a Bluetooth access point. At this time, the Bluetooth access point that receives the transmission attempt confirms whether the current line of the wired telephone network is occupied by another one-phone terminal (S110), and if not occupied, performs the transmission using the wired telephone network (S120).

On the other hand, if the line of the wired telephone network is occupied by another one-phone terminal, and transmits a message for requesting the line switching, such as CDMA or VoIP to the one-phone terminal (S130).

At this time, the user of the one-phone terminal selects whether to respond to the line switch request (S140). Here, the user terminal may select a desired third communication mode of CDMA or VoIP.

In response to the communication mode, selection and line switching, the one-phone terminal performs a line switching command (S160).

When the mobile communication mode is selected, the connection with the Bluetooth access point may be released, the mobile communication mode may be returned to the mobile communication mode, and the transmission may be performed through a normal mobile communication transmission procedure.

On the other hand, if VoIP is selected, the voice call is digitally converted through the VoIP call connection processing unit to make an IP packet, and then the transmission is performed through the gateway.

On the other hand, the incoming call processing for the multiple calls performs a similar process.

In the case of an incoming call, since the mobile communication mode can be operated separately from the Bluetooth mode, the incoming signal of the mobile phone number can be immediately detected. On the other hand, when connected to Bluetooth mode, the home location registration server (HLR) registers the telephone number of the wired network to which the Bluetooth access point is connected. It may be determined whether it is occupied (S110), it may be inquired to the Bluetooth communication network whether to transfer to the wired network (S130, S140).

In addition, when the wired telephone network is converted to a VoIP call, the wired telephone number is converted to an IP address through a gatekeeper to set up a call through a gateway.

That is, according to the embodiment of the present invention, the technical idea of identifying the line occupancy of the wired telephone network or the mobile communication network and inquiring or automatically switching the line through the Bluetooth access point is consistent.

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 terminal can expect the effect that can be used without limiting the individual incoming / outgoing functions of the one-phone terminal by automatically or selectively switching to another line even when another one-phone terminal occupies the line. Can be.
