Description

Asynchronous mode mobile terminal and a network setup method using the terminal}

The present invention relates to an asynchronous mobile communication terminal and a network setting method using the same. The present invention relates to a terminal and a network setting method using the same, which can automatically suggest a solution when the terminal is implemented in a user-selected mode. .

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 three most widely used digital with Frequency Division Multiple Access (FDMA) and Code Division Multiple Access (CDMA). It is one of the wireless telephone technologies.

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

1 is an exemplary view showing a schematic configuration of such an asynchronous mobile communication system. As shown, a base station (BTS / Node B) 210 performing a radio access function according to the 3GPP radio access standard with the wireless terminal 100, base station protocol matching and control, soft handoff, core network protocol processing, etc. ATM-based switching and switching for a Radio Control Station (BSC / RNC) 220 performing a function, a Radio Switching System (MSC) 230 for implementing a switching operation for performing a Circuit Traffic Service, and a GPRS service. 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 user mode, the network is not found when the network is moved to another area without the network.

That is, as shown in FIG. 2, suppose that the operator using the communication service moves to the "B" region by setting the communication network of the "a" network operator in the "A" region to a manual selection mode. . For example, suppose a terminal user travels from "Germany" to "France." Since the terminal is set to the user mode, if there is no change of the user's setting, the network of the selected network "a" operator is not found in the "B" region.

Therefore, as shown in FIG. 3 through the display unit, only “No service” is displayed, and no separate operation is performed. This is because the network selected by the user selection mode set inside the terminal is maintained. Therefore, when using the asynchronous mobile communication terminal, when the user selection mode (user selection mode) is set, the user is inconvenient about the service limitation due to the change in location.

An object of the present invention is to provide an asynchronous mobile communication terminal and a network setting method using the same, which can solve the inconvenience that a user experiences when leaving the service area in the user selection mode.

Another object of the present invention is to provide an asynchronous mobile communication terminal and a network setting method using the same, which can suggest a solution to a user in a state out of a service area.

The present invention for achieving these objects is an automatic mode, the user selection mode of the currently searched network or the current network when the operation in the selected network is impossible when using the asynchronous mobile communication terminal implemented in the network selected by the user mode It is characterized by providing a choice of any one of maintenance.

As described above, the asynchronous mobile communication terminal according to the present invention can be expected to provide an effect that can present a solution to the user when 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. Hereinafter, with reference to the accompanying drawings illustrating the configuration and operation of the embodiment of the present invention, the configuration and operation of the present invention shown in the drawings and described by it will be described by at least one embodiment, By the technical spirit of the present invention described above and its core configuration and operation is not limited.

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

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

The input unit 120 includes 0 to 9 numeric key buttons, a menu button (menu), a cancel button (clear), an OK button, a call button (TALK), an end button (END), an internet access button, a navigation key and a text. A plurality of function keys such as an input key may be provided. The controller 130 provides key input data (eg, network setting selection) corresponding to a key pressed by the user.

The memory unit 140 includes a read only memory (ROM) and a random access memory (RAM). The ROM stores microcode and various reference data of a program for processing and controlling the controller 130. The RAM is a working memory of the controller 130 and stores temporary data generated during the execution of various programs. In addition, the memory unit 140 may include a subscriber identification card (SIM; Subscriber Identification Module) (SIM) that can be mounted or detached in the terminal and stores various types of information of the user, including the microprocessor and the memory chip itself. can do.

The display unit 150 displays status information generated during the operation of the terminal, a limited number of characters, a large amount of video and 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 performs the function of channel decoding the received signal by decreasing the frequency of the radio frequency signal received through the antenna when receiving, and channel coding the data and raising the frequency when transmitting. Transmit through the antenna.

The controller 130 controls the overall operation of the terminal. For example, if a user performs a process and control for voice call and data communication through a communication network of a network operator set to a user selection mode, and detects an inability of a network transmission / reception service through the wireless communication unit 110, the user The network setting screen is controlled to provide a network setting screen to the user, and the network setting is controlled according to a user's selection signal provided through the input unit 120.

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

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

If the user moves to an unserviceable area in a state set in the form of a user mode, the service becomes inoperative. This may be the case when a user moves to another country or to a place where a signal of a corresponding network service is not reached. The controller 130 continuously detects a communication service unavailable state.

If the service unavailable state is detected (S501), as shown in FIG. 6, the service selection state guide information is provided through the display device along with the network selection setting screen. The network setting screen provides a menu for user selection. That is, a menu including items of 1. auto (auto mode), 2. Choose net (user selection), and 3. Cancel is displayed (S502, S503).

If the user selects 1. auto (auto mode), the network is rescanned at the current location of the terminal, and the network is selected according to the information set in the terminal internal memory based on the search result. Display the changed network information to the user. That is, suppose that the network "a" is selected and used in the "A" region and then moved to the "B" region as shown in FIG. At this time, if the terminal internal memory uses the network of the network operator "2" in the area "B", and is used by default, a message is displayed to the user that the automatic change to the network network of the network operator "2". Of course, in some cases, there will be a preferred network or avoiding network operators for each network provider, so that it may not be displayed to the user as needed. In addition, if there is no information set in the terminal internal memory, it may be possible to change to the network operator having the strongest signal strength among the detected network operator's signals (S506). A communication function is performed using the changed communication network of the network operator (S507).

On the other hand, if the user selects 2. choose net (S505) (S505), it searches for a network that can communicate at the current location and displays the result (S508).

Subsequently, the user receives a user selection signal provided through the input device, accesses the selected network, and performs a communication service (S509).

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

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

The controller 130 continuously detects a communication service unavailable state. When detecting a service unavailable state (S701), a service unavailable state guide screen is provided through a display device (S702).

Subsequently, a searchable network is searched from the location of the current terminal (S703).

As a result of the search, it is determined whether there is an accessible network (S704), and if not, a screen is displayed on the display device asking the user to re-search with the search result (S708).

If the user rescans (S709), the process returns to step S703 for network retrieval, and if the user does not select rescan, the current user mode is maintained (S710).

On the other hand, if there is an accessible 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. In addition, if there is no information set in the terminal internal memory, it may be possible to change to the network operator having the strongest signal strength among the searched network operator's signals (S705).

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

8 is a flowchart illustrating a process of setting up a network according to another embodiment of the present invention. Suppose that the terminal user who used the "a" network in the "A" country as the user mode (manual mode) moved to the "B" country. As mentioned above, if the user leaves the service area, a service unavailable message will be displayed, and the user may forget that the user mode is set, and may think that there is a problem with the terminal or the network operator. In order to solve this problem, consider a case in which the user powers off and powers on the terminal while displaying a service unavailable message.

If a booting operation is started while power is supplied (S801), the current network setting information is read (S802).

Check whether the current setting state is set to the user mode (S803), and if it 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 may be maintained without additional control (S805).

On the other hand, in the detailed description of the present invention has been described with respect to specific embodiments, it can be modified in various forms without departing from the scope of the invention.
