Description

[0001] The present invention relates to an asynchronous mobile communication terminal and a network setting method using the same,

The present invention relates to an asynchronous mobile communication terminal and a network setting method using the same, and more particularly, to a terminal capable of automatically providing a solution when a terminal that is implemented in a user selection mode is out of a network area and a network setting method using the same .

Global System for Mobile communication (GSM) is a digital mobile phone system widely used in Europe and elsewhere. This GSM is a variant of Time Division Multiple Access (TDMA), which is the most widely used three digital (CDMA), with frequency division multiple access (FDMA) and code division multiple access It is one of the wireless telephony technologies.

The GSM digitizes and compresses the data, then sends it along one channel with two different user data, each of which is sent in its own time band. This GSM can operate in both the 900 MHz and 1800 MHz frequency bands. WCDMA (Wideband Code Division Multiple Access) is an asynchronous mobile communication system using CDMA based on the above-mentioned GSM and General Packet Radio Services (GPRS).

FIG. 1 is an exemplary view showing a schematic configuration of such an asynchronous mobile communication system. A base station (BTS / Node B) 210 that performs a wireless connection function according to the 3GPP wireless connection standard with the wireless terminal 100, and a wireless base station controller 210 that performs base station protocol matching and control, soft handoff, (BSC / RNC) 220 performing a function for performing a circuit service, a wireless switch (MSC) 230 implementing a switching operation for performing a Circuit Traffic Service, and an ATM- And a Serving GPRS Support Node (SGSN) 240 that provides a routing connection.

In this asynchronous mobile communication system, when the network selection is set to the manual mode, when the mobile station moves to another area where the network is not present, the selected network is not found.

In other words, suppose that the operator who has used the communication service by moving to the "B" region by setting the communication network of the network operator "a" in the "A" region to the manual selection mode . For example, suppose a terminal user travels from "Germany" to "France". If the user does not change the setting because the terminal is set to the user mode, the network of the selected network "a" can not be found in the area "B".

Therefore, as shown in FIG. 3, "No service" is displayed through the display unit and no separate operation is performed. This is because the network selected by the user selection mode set in the terminal is continuously maintained. Therefore, when the asynchronous mobile communication terminal is used, the user is inconvenienced in the service restriction due to the variation of the position when the user is set to the user selection mode.

It is an object of the present invention to provide an asynchronous mobile communication terminal and a network setting method using the same, which can solve the inconvenience experienced by a user when a user leaves the service area in a state of being set in a user selection mode.

It is another object of the present invention to provide an asynchronous mobile communication terminal capable of presenting a solution to a user in a state outside a service area, and a network setting method using the same.

According to an aspect of the present invention, there is provided an asynchronous mobile communication terminal, which is implemented in a network selected by a user mode, Or maintenance.

As described above, the asynchronous mobile communication terminal according to the present invention can be expected to provide a solution to the user when the mobile communication terminal is out of the service area while operating in the user mode.

Other objects, features and advantages of the present invention will become apparent from the detailed description of the embodiments with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a configuration and an operation of an embodiment of the present invention will be described with reference to the accompanying drawings, and the configuration and operation of the present invention shown in and described by the drawings will be described as at least one embodiment, The technical idea of the present invention and its essential structure and action are not limited.

4 is a block diagram showing a schematic configuration of a mobile communication terminal according to the present invention. The terminal 100 according to the present invention includes a wireless communication unit 110, an input unit 120, a controller 130, a memory 140, and a display unit 150.

The wireless communication unit 110 implements a circuit service and a packet service. To do this, it consists of an asynchronous module that performs transmission and reception of radio signals.

The input unit 120 includes numeric key buttons 0 to 9, a menu button, a cancel button, an OK button, a call button TALK, an end button END, an Internet access button, An input key, and the like. And provides key input data (e.g., network setting selection) corresponding to the key pressed by the user to the control unit 130. [

The memory unit 140 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM stores the microcode of the program for processing and controlling the control unit 130 and various reference data. A RAM (RAM) is a working memory of the controller 130, and stores temporary data generated during execution of various programs. The memory unit 140 may include a SIM (Subscriber Identification Module) card, which may be mounted on or detached from the terminal, and stores various information of the user including the microprocessor and the memory chip. can do.

The display unit 150 displays status information generated during operation of the terminal, limited number of characters, a large amount of moving images, still images, and the like. The display unit 150 may use a color liquid crystal display (LCD).

The communication unit 110 may include a Universal Mobile Telecommunications System (UMTS) module and a Global System for Mobile Telecommunication (GSM) module.

The UMTS module operates when the third generation communication mode is selected under the control of the controller 130. [ The GSM module operates when the second generation communication mode is selected under the control of the controller 130. [ The basic operation of each module is to perform channel decoding of a received signal by lowering the frequency of a radio frequency signal received through the antenna when receiving, channel coding the data when transmitting, And transmits it through the antenna.

The controller 130 controls the overall operation of the terminal. For example, when a disabling state of a network transmission / reception service through the wireless communication unit 110 is detected, the processing of the voice communication and the data communication is performed through the communication network of the network provider set in the user selection mode, And controls the network setting according to a user's selection signal provided through the input unit 120. [

The configuration of the mobile communication terminal according to the present invention has been described above. Hereinafter, a network setting method according to an embodiment of the present invention will be described.

FIG. 5 is a flowchart illustrating a procedure of a time information setting method according to the present invention.

If the user moves to the service disabled area in the state of the manual mode, the service becomes disabled. This may be the case where the user moves to another country or moves to a location where the signal of the corresponding network service is not reached. The control unit 130 continuously detects the communication service disabled state.

When the service disabled state is detected (S501), a network selection setting screen is provided together with the service disabled state guidance information through the display device as shown in FIG. The network setup screen provides a menu of choices for the user. That is, a menu including items of 1. auto (automatic mode), 2. Choose net (user selection), and 3. cancel (cancel) is displayed (S502 and S503).

If the user selects 1. auto (automatic mode), the network is rescanned at the current location of the terminal, the network is selected according to the information set in the terminal internal memory based on the retrieved result, And displays the automatically changed network information to the user. That is, as shown in FIG. 2, assume that the user selects and uses the network "a" in the "A" region and then moves to the "B" region. At this time, if the terminal internal memory is used as a default by using the communication network of the network operator "2" in the area "B", the message indicating that the user has automatically changed to the network operator network "2" is displayed. Of course, in some cases, there may be a preferred network or a avoided network provider for each network provider, so that it may not be displayed to the user as needed. If there is no information set in the internal memory of the terminal, it may be possible to change to a network operator having the strongest signal strength among signals of the searched network provider (S506). The communication function is performed using the network network of the changed network provider (S507).

On the other hand, if the user selects 2. choose net (network selection) (S505), the network capable of communication at the current location is searched and the result is displayed (S508).

Next, a user selection signal provided through the input device is received, and a communication service is performed by connecting to the selected network (S509).

In some cases, the signal may temporarily reach a weak section. Therefore, if the user selects 3. cancel, the presently set network operator is assumed to be maintained. At this time, the screen of the terminal displays "Out of Service!".

7 is a flowchart illustrating a procedure of a network setting method according to another embodiment of the present invention. Unlike the first embodiment, this embodiment does not provide the user with a setting opportunity.

The control unit 130 continuously detects the communication service disabled state. When the service disabled state is detected (S701), a service disabling state guidance screen is provided through the display device (S702).

Next, a connectionable network is searched for at the current location of the terminal (S703).

If it is determined that there is no connectable network (S704), a screen for asking the user to search for the search together with the search result is displayed on the display device (S708).

If the user rescan the network (S709), the process returns to step S703 for the network search. If not, the current user mode is maintained (S710).

On the other hand, when there is a connectable network, the network is selected and connected according to the setting information stored in the terminal internal memory. As mentioned above, when changing to the automatic mode, the target network is selected based on the option information related to the change. If there is no information set in the internal memory of the terminal, it may be possible to change to a network operator having the strongest signal strength among signals of the searched network provider (S705).

The currently set user mode is switched to the automatic mode (S706), and the automatically changed network information is displayed to the user. That is, a message indicating that the user has automatically changed to the network operator network "***" is displayed. Of course, it may not be displayed to the user in some cases (S707).

8 is a flowchart illustrating a procedure of a network setting method according to another embodiment of the present invention. Assume that the terminal user who has used the network "a" in the "A" country as the manual mode and moved to the "B" country. As mentioned above, when the user leaves the service area, a service disabled message will be displayed, the user may forget that the user mode is set, and think that there is a problem with the terminal or the network operator. In order to solve such a problem, consider a case where the user turns the power of the terminal off and then powers-on in the state that the service disabled message is displayed.

When a booting operation is started with power being supplied (S801), the current network setting information is read (S802).

If the current setting state is set to the user mode (S803), and if the current setting state is set to the user mode, it is forcibly switched to the automatic mode (S804). If the current automatic mode is set, the automatic mode is maintained without any additional control (S805)
