Description

System and method for controlling built-in Bluetooth module using mobile communication base station identifier {System and method for controlling bluetooth module within one-phone terminal using identifier of cellular basestation}

The present invention has a built-in Bluetooth module that can be used as a mobile communication terminal in the outdoors and mobile, the operation control method and system of a Bluetooth module of a one-phone terminal that can be used as a wireless telephone using a wired telephone network within Bluetooth coverage It is about.

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 cordless phone using wired telephone network. Ericsson, Nokia and others 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.

However, even in the existing mobile communication terminal, a power control method for reducing power consumption is recognized as a major technology to be solved by those skilled in the art. Therefore, the one-phone terminal with the built-in Bluetooth module is inevitably reduced in use time because the power used to activate the Bluetooth module is consumed in addition to the power used for mobile communication.

In general, in order to reduce the power consumption of the Bluetooth module in one phone, a user directly controls the operation of the Bluetooth module.

In another conventional technology, a method of changing the monitoring period of the Bluetooth access point in inverse proportion to the strength of the signal received from the Bluetooth access point is considered, but the power reduction is required because the monitoring of the Bluetooth access point must be continuously performed. There is a limit.

The present invention provides a system and a control method for reducing power by controlling the operation of a Bluetooth module in a one-phone terminal that can use a mobile communication service and a wireless telephone service using a wired network.

More specifically, the technical problem of the present invention is to reduce the battery usage time due to the additional power consumption generated by the Bluetooth module, and automatically cuts off power applied to the Bluetooth module outside the coverage of the Bluetooth access point. In addition, the present invention provides a method and system that can be controlled in a state in which a wireless telephone application is possible by applying power to a Bluetooth module within Bluetooth access point coverage.

In order to solve the above problems, the Bluetooth module control method of the one-phone terminal according to a feature of the present invention,

a) registering an identifier of the mobile communication base station in the region where the Bluetooth access point exists in the database of the one-phone terminal;

b) detecting a change of a mobile communication base station in which the one-phone terminal is present;

c) retrieving the identifier of the changed mobile communication base station from the database;

d) activating the Bluetooth module when the identifier of the mobile communication base station exists in the database, and deactivating the Bluetooth module when the identifier of the mobile communication base station does not exist in the database.

Here, in step a), the one-phone terminal acquires and registers an identifier of a mobile communication base station from the Bluetooth access point while performing bonding with the Bluetooth access point.

In addition, the obtained mobile communication identifier may be registered in the database together with the Bluetooth link key and whether or not the wireless telephone application.

On the other hand, the step d) further comprises the step of determining whether the current mobile phone terminal occupies the Bluetooth traffic channel, if the mobile communication base station identifier does not exist in the database, the one-phone terminal is occupied Bluetooth traffic After termination, the process of inactivating the Bluetooth module may be further performed.

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 method for controlling a Bluetooth module according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic diagram showing a usage environment of a one-phone terminal for explaining an embodiment of the present invention.

The usage environment of the one-phone terminals 100a, 100b and 100c is a cell A and C of the base stations 300a and 300c to which the Bluetooth access points 200a and 200c belong and a cell of the base station 200b where the Bluetooth access point does not exist. Can be divided into (C).

In order to switch to the Bluetooth communication mode, the one-phone terminal monitors the Bluetooth access point, and when it enters the coverage, switches to the Bluetooth mode manually or automatically to perform Bluetooth communication.

On the other hand, when the one-phone terminal is out of the Bluetooth access point to perform the mobile communication through the mobile communication base station (300a, 300b, 300c).

The Bluetooth access point can exist in any base station cell, but the number of mobile communication base stations capable of Bluetooth communication is limited because the one-phone terminal can be called and received as a wireless telephone at a specific Bluetooth access point.

On the other hand, in the conventional CDMA mobile communication system, each base station apparatus 300a, 300b, 300c has its own base station identifier. The Bluetooth access point, which is fixedly or temporarily installed in the base station, may store an identifier of the base station.

For example, in the system shown in FIG. 2, the Bluetooth access point 200a stores the identifier of the base station 300a, and the Bluetooth access point 200c stores the identifier of the base station 300c. The stored base station identifier is registered in a database of a one-phone terminal which performs bonding to the Bluetooth access point.

3 is a flowchart illustrating a step of registering a mobile communication base station identifier according to an embodiment of the present invention.

The Bluetooth device performs bonding with the Bluetooth access point in a state where the Bluetooth module is activated (ON) (S100 and S110). In the bonding process, the Bluetooth access point determines whether the application of the Bluetooth device applies the wireless telephone (S120).

 In step S120, when the Bluetooth device performing the bonding uses a wireless telephone application, that is, when it is determined as a one-phone terminal, the Bluetooth device transmits and registers a mobile communication base station identifier corresponding to the Bluetooth access point to the one-phone terminal (S130). . If the wireless phone application is not required, the bonding process is completed and the registration process is terminated (S140 and S150).

According to the embodiment of the present invention described above, the mobile communication base station identifier included in the Bluetooth access point is transmitted to the one-phone terminal which has been connected at least once and stored in the database. Accordingly, the one-phone user can acquire and store the mobile communication base station identifier regardless of whether the Bluetooth access point is in the fixed mode or the floating mode without any additional manipulation.

4 is a block diagram showing a Bluetooth module control system of a one-phone terminal according to an embodiment of the present invention.

The one-phone terminal 100 according to the embodiment of the present invention includes a base station identifier receiving unit 110, a base station identifier database 120, a Bluetooth module power control unit 130, and a Bluetooth module 140 for receiving a base station identifier through an external antenna. Bluetooth traffic channel monitoring unit 150 is included.

Although not shown in FIG. 4, the one-phone terminal 100 is obvious to those skilled in the art having a CDMA module for performing CDMA communication, a mode switching unit capable of mutually converting between the CDMA mode and the Bluetooth mode.

The base station identifier receiving unit 110 receives an identifier of a base station currently performing communication when a base station change is detected in a mobile communication mode, or receives a base station identifier from a Bluetooth access point in a Bluetooth bonding procedure. In FIG. 4, the base station identifier receiver 110 is represented by one block. However, the apparatus for receiving base station information in the mobile communication mode and the Bluetooth mode may be received through a separate interface.

The base station identifier received in the Bluetooth bonding procedure is transmitted to the base station identifier database 120 and stored. The base station identifier may be stored together in correspondence with a Bluetooth link key or Bluetooth application. The base station identifier of the Bluetooth access point may be received from the Bluetooth module 140 as Bluetooth master device information during Bluetooth bonding.

When the base station change occurs in the mobile communication mode, the received base station identifier is transmitted to the Bluetooth module power control unit 130. When the base station change occurs, the Bluetooth module power control unit 130 searches whether the changed base station identifier is registered in the mobile communication base station identifier database, and in the case of the mobile communication base station area where the Bluetooth access point exists, the Bluetooth module 140. Notify it and activate the monitoring of the Bluetooth access point.

The Bluetooth traffic channel monitoring unit 150 monitors the Bluetooth traffic channel of the one-phone terminal and notifies the Bluetooth module power control unit 130 if the current Bluetooth traffic channel is in use. 140) to deactivate.

5 is a flowchart illustrating a control method of a Bluetooth module according to an embodiment of the present invention.

Since the one-phone terminal having the database of the Bluetooth access area recognizes the change of the mobile communication base station device in real time according to the movement of the user having the Bluetooth connection area, the operation of the Bluetooth module is controlled when the mobile communication base station device changes. .

If the change of the mobile communication base station that the terminal is currently communicating with the movement of the user having the one-phone terminal is detected, the one-phone searches for an available mobile communication base station identifier database (S200).

In step S220, it is determined whether the identifier of the mobile communication base station currently connected to the database is included. If the base station identifier is included in the database (YES), the operation state of the current Bluetooth module is analyzed (S300). If the module is in the OFF state, the module is switched to the active state (S310), and if the module is already in the ON state, the Bluetooth module is maintained (S320).

On the other hand, if the database search result does not include the identifier of the currently connected mobile communication base station device, the current state of the Bluetooth module operation is analyzed and if the module is in the OFF state, the module is inactivated (S410). It determines whether traffic channel is occupied (S420).

If the current Bluetooth traffic channel is not occupied, the Bluetooth module is immediately switched to an inactive state (S421). If the traffic channel is occupied, it is switched to an inactive state after the end of the traffic channel (S422).

According to the above-described embodiment of the present invention, when a change of the mobile communication base station identifier occurs, the one-phone terminal checks whether the mobile communication base station exists in the Bluetooth access point and supplies power to the Bluetooth module only in the region in which the Bluetooth access point exists. This reduces the overall power consumption of the one-phone terminal.

On the other hand, the identifier of the mobile communication base station that the one-phone terminal is capable of wireless telephony communication using Bluetooth may be changed by the cell design of the mobile communication provider, so it is necessary to prepare for this.

6 is a flowchart illustrating a method of updating a mobile communication base station identifier corresponding to a Bluetooth communication area according to an embodiment of the present invention.

 When the terminal power is turned on (S50), the same terminal initialization procedure as before is performed (S52).

At this time, the Bluetooth module in the one-phone terminal is once activated (S70). Then, in step S80 it is checked whether the Bluetooth access point and wireless telephone application is possible.

If the Bluetooth access point and the Bluetooth connection are possible, the one-phone enabled mobile communication base station identifier is updated with the identifier of the currently connected mobile communication base station (S81), and the Bluetooth module is kept ON to operate (S82).

If the connection with the Bluetooth access point is not possible, the Bluetooth module is turned off (S83).

Therefore, according to the embodiment of the present invention, even if the mobile communication base station apparatus is changed by the cell change, it is possible to easily update the database through the terminal ON / OFF operation.

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, since the Bluetooth module operates only in an area where a wireless telephone application using Bluetooth is possible, a remarkable effect of automatically reducing power required by the one-phone terminal can be expected without a user's operation.
