Abstract

PURPOSE: A method for supplying origination information in a mobile communication terminal is provided to offer the transmitter information immediately when an incoming mobile communication terminal receives a page message on a mobile communication network. CONSTITUTION: The incoming mobile communication terminal determines whether the page message is received from a base station or a base station controller(301). When the page message is received and a telephone number of an originating part is read(302), it is checked whether image information and voice information corresponding to the received telephone number exist(303). If the information corresponding thereto does not exist, a CPU outputs reference voice information set in advance to a speaker/buzzer part via a voice process part(304). If the CPU has found out the information corresponding thereto, it outputs the found image information to a display part, and applies the found voice information to the speaker/buzzer part(305).

Description

Method for providing caller information in mobile terminal {Method for providing caller information in a mobile station}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal. In particular, when a paging call is received by a called mobile terminal in a mobile communication network, the mobile communication terminal can provide an image of a caller inputted in advance to the called mobile terminal. The present invention relates to a method for providing caller information of a terminal.

In general, in the wireless communication network shown in FIG. 1, each of the mobile communication terminals 10a to 10n checks whether or not there is a message transmitted from the base station and the base station controller 20 to the mobile switching center 30 in the reception mode. do. Because the mobile communication terminal should be able to wait for a long time with a minimum power consumption, it does not always check the received message provided by the mobile switching center 30 and only receives the received message only in a predetermined period with the base station and the base station controller 20. Check it.

Therefore, when the called party's mobile communication terminal receives the call signal provided by the calling party's phone, the called party's terminal notifies the user of the preset call signal. For example, if a telephone ring is selected, a ringing tone will sound, and if a vibration mode is selected, the vibration motor will rotate.

However, in such a mobile communication network, when a specific mobile communication terminal receives a call signal, it cannot know who the caller is until the caller is called. This is because the current base station and base station controller 20 has the caller registration information but does not provide it to the called party.

On the other hand, a service for displaying some information of the caller may be provided, and the mobile service provider may identify a caller line identification (CLID) that displays the caller's telephone number among the caller's registration information on the called party's mobile terminal when receiving a call signal. Services.

In addition, a call signal for each caller is changed according to the caller's telephone number, and when a call is received, a service for informing that the call is received using the set call signal is also provided. In this case, the provided call signal may be made on a mobile communication terminal according to a user's preference, or may be downloaded and used by a call signal provided by a service provider that provides various kinds of call signals.

Therefore, the called party of the mobile terminal can determine who is the caller before the call is started, and can reject the call if the caller does not want the call.

The operation of the caller identification service will be described in more detail as follows.

When a caller of a specific mobile or wired terminal calls a number of a specific called party in the mobile communication network as shown in FIG. 1, the terminal is connected to the home location register 60 connected to the mobile switching center 30 through the base station and the base station controller 20. Register the registration information (for example, telephone number and ESN). At this time, when the mobile communication provider provides a service for informing the calling party's telephone number to the called party's mobile terminal, the base station and the base station controller 20 move the calling party's telephone number recorded in the home location register 60 to the called party's side. Included in the page signal transmitted to the communication terminal (PAGE MESSAGE) and transmitted. Accordingly, the called-party mobile communication terminal has the received telephone number and then provides the information to the display device of the called-party mobile communication terminal when the final traffic channel (TRAFFIC CHANNEL) is established. At this time, the home / visitor location register 60 simply transmits the caller's number to the called party, and the actual screen display is provided by the terminal.

Each mobile communication terminal is supported to enable such a caller identification service in software. That is, the receiving terminal periodically searches for a call signal transmitted from the base station and the base station controller 20 to recognize the caller's telephone number. Therefore, the central processing unit of the called-party mobile communication terminal recognizes the caller's telephone number among various messages output from the modem of the terminal, and provides the caller's telephone number through the speaker or the buzzer of the mobile communication terminal. In this case, as described above, when the called-side mobile communication terminal sets the call signal provided by the terminal or the call signal downloaded from the service provider according to its own preference, the processor transmits the call signal stored in the memory to the central processing unit. The voice signal is converted into an audible call signal by the codec of the called mobile terminal and output through a buzzer or a speaker.

However, according to the related art described above, when the called-party mobile communication terminal receives the call signal, it merely displays the caller's telephone number or rings a stored call signal corresponding to the caller's telephone number. In this way, there is a limit to accommodating a large number of subscribers. In addition, when different types of call signals of subscribers stored in the mobile communication terminal are set, it is difficult to distinguish who is the call signal as the number of subscribers stored is higher, thereby satisfying the needs of customers in the IMT2000 communication network where multimedia services are provided. There is a difficulty.

In addition, when the user of the mobile communication terminal did not hear the call signal or when the call was not made due to a short time, the caller could not know who the caller was. Therefore, the mobile communication service provider provides a service that can leave the caller's voice or contact information in the voice mailbox when the user of the called terminal does not answer the call. However, the current caller is not using the voice mailbox well because there is no other party, and the user of the called terminal has an inconvenience in that the user needs to check the voice information in the voice mailbox by operating the terminal.

The present invention has been made in view of the above problems, and when a specific called party mobile communication terminal receives a call signal in a mobile communication network, the mobile communication terminal can simultaneously provide caller information when the call signal is received. An object of the present invention is to provide a method for providing caller information of a terminal.

Here, when there is image information corresponding to the caller's telephone number without a call being received by the user of the called party's mobile communication terminal, the called terminal outputs image information corresponding to the caller. It has its features.

In addition, the called-side mobile communication terminal is characterized in that it further comprises the step of creating and storing the image information in the memory.

According to the present invention as described above, when a call signal is received from a specific called party terminal in a mobile communication network, image information of the caller may be provided to the called party terminal. Accordingly, even if the user of the mobile communication terminal does not hear the call signal or if the user cannot leave the call for a while, the caller's image information is displayed on the LCD of the terminal. There is an advantage that can be easily known.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing the configuration of a mobile communication terminal employed in the execution of the method for providing caller information of the mobile communication terminal according to the present invention.

Referring to FIG. 2, the mobile communication terminal 10 according to the present invention controls a radio frequency receiver 11 for receiving information transmitted through one call channel and controls the overall operation of the mobile communication terminal 10. A central processing unit (CPU) 12, a memory 15 for storing information output from the central processing unit 12, and an interface processing unit 18 for interfacing data provided from the outside and storing the data in the memory 15. ), An image processor 14 for processing an image signal included in the information output from the memory 15, an LCD display unit 13 for displaying an image signal output from the image processor 14, and A voice processor 16 for processing a voice signal included in the information output from the memory 15, and a speaker / buzzer 17 for representing the voice signal output from the voice processor 15.

In the embodiment of the present invention, the interface processing unit 18 uses the UART (Universal Asynchronous Receiver Transmitter) serial port that can interface with the memory 15 and the user's computer used in the existing mobile communication terminal 10 do.

When a call signal is received by the mobile communication terminal having the above configuration, a caller information providing process will be described with reference to FIG. 3.

First, a user of each mobile communication terminal 10 creates an image of another subscriber to be stored in the memory 15 of the mobile communication terminal. That is, a BMP file that can be used on a mobile communication terminal after drawing, downloading, or scanning and storing image files or photos for other subscribers as desired using a computer or other image processing apparatus. And so on. In this case, the files to be stored in the mobile communication terminal should be a color that can be supported on the mobile communication terminal. If the mobile communication terminal uses a black and white LCD, the image to be stored should be black and white, whereas when using a color LCD, the color image may be stored. In addition, since the sizes of LCDs of all mobile communication terminals are not equal to each other, a standardized standard should be set so that the file size and the file size of an image can be commonly used by all subscribers subscribed to the entire mobile communication network.

Subsequently, the user reads a file converted for the terminal using a serial port or a universal serial bus (USB) port while switching the mode of the mobile terminal to the data mode, and then reading the terminal. Reboot. Then, the mobile communication terminal is rebooted and at the same time read the files stored in the memory 15 can be used on the terminal.

Subsequently, the user stores the files read in this manner so as to have a one-to-one correspondence with a telephone number he / she wants to designate on the mobile communication terminal.

Accordingly, each user can designate and store images of all subscribers desired by the user and a corresponding telephone number on the mobile terminal in the manner described above.

When a particular calling party terminal makes a call to a particular called party mobile terminal while the initial condition is satisfied, the mobile switching center notifies the home location register (HLR) 60 connected to the called party mobile terminal. The home location register (HLR) 60 searches for a visitor location register (VLR) 70 that manages the called party's mobile communication terminal, and notifies the visitor location register (VLR) 70 of the current situation. Therefore, the visitor location register (VLR) 70 requests the base station and the base station controller 20 to call the called mobile terminal in the information table managed by the visitor location register (VLR). Accordingly, the base station and the base station controller 20 transmits a page signal to the called party's mobile terminal in order to respond to the request. At this time, when the called-party mobile communication terminal sends an access probe to the base station and the base station controller 20, a substantial communication channel is established to allow a call between the called-party and the calling-terminal user.

Here, when the base station and the base station controller 20 transmits a page message to the called-side mobile communication terminal, the operation of the called-side mobile communication terminal will be described in detail.

First, the called-party mobile communication terminal determines whether a page message transmitted from the base station and the base station controller 20 has arrived at regular intervals (step 301). On the other hand, the base station and the base station controller 20 transmits various types of messages. Among these messages, messages transmitted to all mobile communication terminals within the area of the base station and base station controller 20 and messages transmitted only to a specific terminal are included. have. For example, a message transmitted to all terminals may be a broadcast message, and a message transmitted to a specific terminal may be a registration request message or a call request message. And, the visitor location register (VLR) connected to the mobile switching center 30 corresponds to the registration of the mobile communication terminal by performing power off to the mobile communication terminal or performing handoff to another visitor location register (VLR) during the movement. It stores the registration information and retrieves the exact location and status of the mobile communication terminal.

At this time, when the called-party mobile communication terminal receives the call signal and reads the caller's phone number (step 302), the central processing unit 12 of the mobile communication terminal is assigned to the received phone number among the images stored in the memory 15. It is determined whether there is corresponding image information and / or voice information (step 303). Subsequently, if there is no corresponding image information and audio information, the CPU 12 outputs a preset reference image to the LCD display unit 13 through the image processing unit 14, and also sets the preset reference audio information (for example, , A ringtone, a buzzer signal, a song, etc.) is output through the speaker / buzzer 17 through the voice processor 16 (step 304). Meanwhile, when the CPU 12 finds the corresponding image information and the voice information, the central processing unit 12 outputs the corresponding image to the LCD display unit 13 through the image processor 14, and also provides the corresponding voice information (for example, a ring tone or a buzzer). Signal, song, etc.) is output via the speaker / buzzer 17 through the voice processing unit 16 (step 305).

At this time, when the user of the called-party mobile communication terminal attempts to access the terminal, a call is established with the calling-party terminal and the called-party mobile communication terminal from this point on, thereby enabling a call (step 306).

On the other hand, when the base station and the base station controller 20 transmits a page message to the called-side mobile communication terminal, the operation when the user of the called-side mobile communication terminal is absent or does not hear the call signal will be described. Same as

According to the present invention, when the user of the called-party mobile communication terminal does not answer the call for a predetermined time, the LCD display unit 13 normally outputs an image file corresponding to the caller's telephone number. Therefore, the called-side mobile communication terminal user can easily check whether or not the call came from the user by looking only at the LCD display unit 13 of the terminal.

As described above, in the method of providing caller information of a mobile communication terminal according to the present invention, when a call signal is received from a specific called party terminal in a mobile communication network, image information of the caller may be provided to the called party terminal. Accordingly, even if the user of the mobile communication terminal does not hear the call signal or if the user cannot leave the call for a while, the caller's image information is displayed on the LCD of the terminal. There is an advantage that can be easily known.
