4 is a control flowchart of a mobile terminal for performing an operation according to a received message when a cell broadcast message is received according to an embodiment of the present invention.

The present invention relates to a control method of a mobile communication terminal, and more particularly, to a control method of a mobile communication terminal using a cell broadcast message received from a network.

In general, a message of a Short Message Service (SMS) or a Cell Broadcasting (CB) service is used to control a service of a mobile communication terminal moving in a network. Here, SMS refers to a service that enables the exchange of short text messages between mobile communication terminals or between a mobile communication terminal and a message input device using a storage center, a forwarding function and an access, paging channel, and a call channel of a message center. In addition, the cell broadcast service uses a paging channel of a CDMA wireless channel in a short message service to send a short message such as weather or traffic conditions to a mobile communication terminal or a specific group of mobile communication terminals from a message input device at a time. It means a one-way message service that sends out.

Therefore, when using a short message service, it is possible to send a 1: 1 message between mobile communication terminals, and when using a cell broadcast service, it is possible to send a message to all mobile communication terminals located in a specific area at one time.

Therefore, the user of the mobile communication terminal by transmitting a control message including the control information to the mobile communication terminal using a short message service or a cell broadcast service, and modifying the control information in the subscriber information module (SIM) through the received control message. UI (User Interface) control is possible.

However, when attempting to modify the information in the SIM by transmitting a control message to the mobile communication terminal using such a short message service or a cell broadcasting service, an overhead occurs due to the modification of the SIM information, so that the user interface is not used. You may be unable to do so. In addition, if a control message is frequently transmitted to a mobile communication terminal, a large amount of transmission may not only interfere with a call but also increase the length of time that a user cannot use a user interface.

In particular, when using a cell broadcast service, a message is transmitted to all mobile communication terminals in a corresponding area set to receive a control message, and since the 1: 1 communication between each mobile communication terminal is required, the overhead on the network side becomes large. . Therefore, the overhead of applying the control message to a specific mobile terminal according to the needs of the user or the operator becomes large.

As described above, when a user wants to control a user interface of a mobile communication terminal by providing control information to all, that is, unspecified, mobile communication terminals in a corresponding area set to receive a service using a control message in a network, a message is transmitted. There was a problem that overhead occurs during this time.

Accordingly, the present invention has been made to solve the above-described problems, and the present invention provides a mobile communication terminal using a cell broadcast message received from a network that enables the mobile communication terminal to be controlled without the overhead between the network and the mobile communication terminal. Its purpose is to provide a control method.

According to an aspect of the present invention, there is provided a method of controlling a mobile communication terminal using a cell broadcast message, the method comprising: analyzing the received cell broadcast message upon receiving the cell broadcast message; Determining whether a code value of a cell broadcast ID field in a cell broadcast message is included within a predetermined range; determining whether the cell broadcast message is a reception rejection object when the code value is included within a predetermined range; And performing a control function corresponding to the cell broadcast ID when the broadcast message is not a reception rejection target.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The present invention is implemented to provide a method for controlling a mobile communication terminal using a cell broadcast (CB) message. To this end, a cell broadcast message including control information is broadcast to a specific region and a specific subscriber in a network, and the target mobile communication terminal receives and processes it so that the mobile communication terminal can be controlled. Such a method may be achieved by determining in advance whether the user is to be provided with a cell broadcast message including control information provided manually, or alternatively, by providing a cell broadcast message to the user unilaterally from the perspective of a mobile terminal operator. It may be done.

Prior to describing the present invention, a brief description of the cell broadcast service used in the present invention.                     

In general, a cell broadcasting service is an application of a short message service, and refers to a service that simultaneously transmits multiple messages to a mobile communication terminal of a user registered with the cell broadcasting service. Business information, advertisements, stock information, news, etc. Included in Some of the contents are paid by the user directly, that is, the content is provided by the user directly set whether or not to provide a service, but the content is unilaterally serviced regardless of the user's intention.

Meanwhile, the Broadcast / Multicast Control (BMC) layer of the protocol layer of the mobile communication system schedules a cell broadcast message transmitted from a network, and transmits the cell broadcast message to a specific cell. The cell broadcast message is transmitted to all terminals located in the cell. Here, the BMC layer is a layer used only for the broadcasting function, and the cell broadcast message is a short message composed of up to 1230 octets composed of letters and numbers only between terminals or between a terminal and a system.

The process of transmitting the cell broadcast message to the mobile communication terminal will be described later. Referring to FIG. 1, which is a diagram schematically illustrating a mobile communication system using a cell broadcast message according to an exemplary embodiment of the present invention, to describe the above process.

As shown in FIG. 1, as an example of a conventional mobile communication system, a mobile communication system of Global System for Mobile Communication (GSM) / General Packet Radio Service (GPRS) / Universal Mobile Telecom munications System (UMTS) may be used for each cell. A cell defining a wireless coverage area established by a fixed site base station located within. In this way, a mobile station (MS) 100, 110, 120 communicating with the base station 130 is located in a cell, which is a wireless coverage area defined by a base station (BS) 130. do. In addition to the above-described mobile communication terminals 100, 110, 120, and the base station 130, the mobile communication system includes a mobile switching center (MSC) 150 and a cell broadcast center (CBC) 160. It is configured to include.

Here, the mobile switching center 150 typically interworks with other mobile switching stations in order to process outgoing / receiving requests from the respective mobile communication terminals 100, 110, and 120. The mobile switching center 150 is created by a user or a mobile operator by allocating an area not used in the channel ID region allocated for cell broadcast message transmission as an ID for controlling the mobile terminal according to an embodiment of the present invention. The short message may be transmitted through the cell broadcast center 160 as the cell broadcast message in a designated transmission range. As described above, although the cell broadcasting message is created and transmitted by the mobile switching center 150, in another embodiment of the present invention, the cell broadcasting center 160 may be created and transmitted to the corresponding mobile communication terminal.

In the following description, the mobile switching center 150 and the cell broadcasting center 160 that provide cell broadcast messages for the mobile communication terminal are collectively defined as the core network 170. That is, in the present invention, the network for providing the cell broadcast message to the mobile communication terminal is referred to as the core network 170.                     

As shown in FIG. 2, the mobile communication terminals 100, 110, and 120 of the mobile communication system include a control unit 200, a memory unit 210, a wireless unit 220, a voice processing unit 230, and a display unit. 240, a key input unit 250 is configured.

Hereinafter, the role of each component of the mobile communication terminal according to the cell broadcast message received from the core network 170 will be described with reference to FIG. 2. To this end, an internal block diagram of a mobile communication terminal according to an exemplary embodiment of the present invention will be described with reference to FIG. 2. Herein, the internal block diagrams of the respective mobile communication terminals 100, 110, and 120 are the same.

Referring to FIG. 2, the controller 200 of the mobile communication terminal performs an overall control operation of the mobile communication terminal. In particular, in the present invention, the control unit 200 receives the cell broadcast message transmitted from the core network 170, and performs the control operation according to the processing result of the received cell broadcast message through a predetermined process. . Here, the predetermined process refers to a process for reading control information included in the received cell broadcast message, and the setting value of the mobile communication terminal is changed according to the read result.

By doing so, in the present invention, the cell broadcast message is broadcast to a mobile communication terminal located in the cell, thereby transmitting control information required by the core network 170 operator to a specific region or an arbitrary user.

In addition, the memory unit 210 connected to the control unit 200 may include a read only memory (ROM), a random access memory (RAM), and a voice for storing a plurality of programs and information necessary for controlling the operation of the mobile communication terminal. Memory, etc. As described above, the memory unit 210 includes a program memory and a data memory, in which program data necessary for controlling the operation of the mobile communication terminal is stored, and in the data memory, during control or during a predetermined operation by a user. Save the generated data. For example, the memory unit 210 stores message data generated for the cell broadcast message input by the key input unit 250. In addition, the memory unit 210 receives a cell broadcast ID value of a cell broadcast message to be rejected by the user and stores the cell broadcast ID value. Accordingly, the controller 200 may store the reception reject list generated by listing the input cell broadcast IDs in the memory 210. That is, the user may prepare a rejection list by pre-listing the cell broadcast IDs for the cell broadcast messages to be rejected.

Subsequently, the wireless unit 220 transmits / receives an RF signal with the base station through the antenna ANT under the control of the control unit 200. The voice signal processor 230 connected to the controller 200 is connected to the microphone MIC and the speaker SPK, and outputs the voice signal received from the microphone MIC to the controller 200. The voice data input from the controller 200 is converted into an audible sound through the speaker SPK and output.

In addition, the display unit 240 receives and displays display data on key input data input from the key input unit 250 under the control of the controller 200, or displays an operation state and a plurality of information of the mobile communication terminal as icons and text. do. In addition, the display unit 240 allows the user to visually know the state in setting or driving a required function under the control of the controller 200. The display unit 240 may display a result of processing the cell broadcast message according to an exemplary embodiment of the present invention.

In addition, the key input unit 250 includes various keys including a numeric key and a character key to provide the controller 200 with key input data input by the user. That is, the key input unit 250 outputs its own key input data according to the input of each key provided, and the key input data output from the key input unit 250 is applied to the control unit 200 so that such key input data is stored. It is detected that the key input data according to the key input, the control unit 200 performs the operation according to the result.

Meanwhile, the cell broadcast message including control information for controlling the mobile communication terminal is transmitted to the mobile communication terminal via the core network 170 such as the base station of the corresponding cell. Then, the mobile communication terminal determines that the message includes the control information through the cell broadcast ID input in the specific field of the received cell broadcast message and completes the reception of the cell broadcast message.

At this time, the transmitted cell broadcast message has a structure as shown in FIG. 3. 3 is a structural diagram of a cell broadcast message according to an embodiment of the present invention. For example, the cell broadcast message has a format structure including a header 310 field indicating that the message includes control information for controlling the mobile communication terminal and a cell broadcast message data field 300 into which the actual short text is input. Have

The header 310 field may include a cell broadcast ID 320, a cell area scope 330, and an update flag 340 according to an embodiment of the present invention. The CB ID 320 is a field to which control information for controlling a mobile communication terminal is allocated according to an embodiment of the present invention. The cell area scope 330 is a cell in a predetermined transmission range or a specific region. The field for selecting an area, and the update flag 340 is a field for setting a flag value for notifying whether or not an update is required. For example, the update flag 340 is a field for preventing a cell broadcast message from being repeatedly received.

In more detail, a cell broadcast ID 350 is assigned a code value for setting control information. A cell broadcast message is provided by determining in advance whether a user is to receive a cell broadcast message including control information provided manually. In order to provide a cell broadcast message to a user unilaterally, a code value of 999 or later, which cannot be modified by the user, is assigned.

For example, the code value within the 0 to 999 times can be modified by the user, so that it is possible to determine whether or not to receive the cell broadcast message. Since the code values after the 999 cannot be modified by the user, the unidirectional value from the core network 170 can be determined. Only reception is possible. When the cell broadcast message configured as described above is created in the core network 170, the cell broadcast message is transmitted from the core network 170 to the mobile communication terminal.

Next, with reference to FIG. 4, which is a control flowchart of a mobile communication terminal for performing an operation according to a received message when receiving a cell broadcast message, according to an exemplary embodiment of the present invention. First, when the mobile communication terminal receives the cell broadcast message as the core network 170 broadcasts the cell broadcast message, the mobile communication terminal interprets the header field of the cell broadcast message to determine that the message includes control information. Accordingly, in the following description, when it is determined that the message includes the control information, it is preferable to perform a process for processing the received cell broadcast message after completing the cell broadcast message reception.

Accordingly, the controller 200 determines whether a cell broadcast message is received in step 400. Then, the controller 200 analyzes the received cell broadcast message by analyzing the contents. As a result of the analysis, the control unit 200 searches for the header 310 field of the cell broadcast message format in step 420 to determine whether there is a predetermined code value in the cell broadcast ID 320 field. If there is no predetermined code value as a result of the determination, the control unit 200 proceeds to step 430 and controls to perform a corresponding function according to the normal cell broadcast message processing.

On the other hand, if a predetermined code value is set in step 420, the controller 200 proceeds to step 440 to determine whether the set code value is within a range that can be set by the user. If the set code value is a code value within a range that can be set by the user, the controller 200 proceeds to step 450 and determines whether reception restriction setting by the user is set for the received cell broadcast message. If it is determined that the reception restriction is set, that is, the cell broadcast message has been rejected, the control unit 200 proceeds to step 460 and informs the user that the cell broadcast message has been rejected. In contrast, in the case of a cell broadcast message that is not a rejection target, the controller 200 proceeds to step 470 and performs a control function corresponding to the set code value. This is done by the controller 200 determining whether to be a rejection target by comparing the cell broadcast ID in the received cell broadcast message with the cell broadcast ID of the reject list.

On the contrary, when the code value set in step 440 is not a code value within a range that can be set by the user, this corresponds to a cell broadcast message unilaterally provided by the core network 170 operator. Proceed to step to perform a control function corresponding to the set code value.

In detail, when the set code value is any one of 0 to 999 times, the controller 200 determines that the code value corresponds to a range in which the user sets whether or not to receive the code. It is determined whether the cell broadcast ID corresponds to the stored reject list.

For example, it is assumed that 50 of the assigned code values of 0 to 999 are code values allocated for setting reception of location information in the mobile communication terminal. Accordingly, when receiving the cell broadcast message in which code value 50 of the cell broadcast ID is set, location information according to the cell broadcast message processing result is displayed on the screen of the mobile communication terminal. In this way, when the code value assigned to set the time information reception is 832, the time information is displayed when the cell broadcast message in which the code value is set is received. In this case, if the user does not want to view the time information, the user may register a cell broadcast message, in which cell number 832 is assigned to the cell broadcast ID, in a reception rejection list in advance.

On the other hand, since the code value assigned after 999 is set by the operator for one-sided information reception, it is not necessary to determine whether to set the reception restriction. In the foregoing description, a specific code value has been described as an example, but all control of the mobile communication terminal is allocated by assigning call transmission / reception control, manner mode switching, and short message transmission / reception control using a reserved code value that has not yet been determined. Of course it is possible.

According to the above-described method, the present invention can control the mobile communication terminal by determining in advance whether the user is to receive a cell broadcast message including the control information provided manually, otherwise the position of the mobile communication terminal operator In unilaterally providing a cell broadcast message to a user, the mobile communication terminal may be controlled. That is, the setting of the mobile communication terminal can be changed according to a code value indicating control information assigned to the cell broadcast ID included in the cell broadcast message.

In the foregoing detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, according to the present invention, since the cell broadcast message is broadcasted in the cell, it is possible to transmit control information required by the core network operator to a specific region or an arbitrary user, and to communicate with the mobile communication terminal according to the cell broadcast message transmission. There is an advantage that no overhead occurs between the networks. In addition, according to the present invention, since control information can be diversified using a preliminary code value that has not been allocated, there is an advantage in that various services such as call transmission / reception control, manner mode, and short message transmission / reception control can be provided.
