The present invention relates to a method of calling a terminal and a state transition method of the terminal in a mobile communication system, and more particularly, to a method of calling a terminal according to the state of the terminal and a state transition method of the terminal.

In general, mobile communication terminals refer to devices that are designed to be carried by a user and communicate with each other while on the move. Such mobile communication terminals include a pager capable of receiving only in one direction, a CT-II having bidirectional but transmitting only, a mobile phone capable of transmitting and receiving in both directions, and a personal digital assistant (PDA). With the rapid development of society, with the rapid advancement into the information society and the development of mobile communication technology, mobile communication terminals have become closely related to our lives. Therefore, the use of mobile communication terminals is becoming common throughout society. Among these mobile communication terminals, mobile phones are the most used and the most common at present.

These mobile phones are capable of basic data services as well as voice calls, and due to competition among carriers, the dead zone is almost eliminated. As the dead zone is eliminated, the use of mobile communication terminals in public places has become a problem. That is, when a call is received by a mobile phone in a public place or a place where many people have a concert, a lecture, a melody set in the mobile phone is output. This situation not only hurts the people around, but also often causes embarrassment to mobile phone users. Therefore, in such a place, the users turn off the mobile communication terminal in the most basic way. As such, when the power of the mobile communication terminal is turned off, there are the following problems.

When the power is turned off, the mobile communication system recognizes the power-off of the mobile communication terminal. Therefore, the call is immediately connected to the voice mailbox when a call of the mobile communication terminal is required by another person who wants to make a call. The voice mailbox will notify the connected user that the subscription customer is powered off. The user can then leave a message in the voicemail. However, this method can simply hang up the phone for people who do not want to leave a message in the voicemail, and even if the person who wants to deliver an urgent message leaves a message, the user cannot confirm it until the user of the mobile terminal is turned on again. there is a problem.

Alternatively, there is a method of setting a vibration mode in a mobile communication terminal. When the vibration mode is set in the mobile communication terminal as described above, when the call is received, the mobile communication terminal notifies the user that the call is received through vibration rather than a ringing tone. However, even in this case, as described above, there is a problem of making a call in a public place. That is, when a user presses a call key or opens a flip to make a call, it may cause damage to those around him. If the user ignores the call and continues to leave the call without performing a call, the mobile communication system determines that the user has moved from the location of the current base station to another location and transmits a call signal to more base stations. To control. Therefore, the use of the channel which is a limited resource of the mobile communication system is increased, and the load of the mobile communication system is increased by performing unnecessary operations in terms of the system.

Another method other than the above two methods is a method of performing an automatic response by the mobile communication terminal itself. That is, there is a method of leaving a memory because the mobile communication terminal cannot receive a call at present. When using this method, the mobile communication terminal must further include a memory for storing voice, and there is a problem that a program for performing such an operation must be developed. Therefore, in this case, the price of the mobile communication terminal is increased, and there is a possibility that the state of the recorded voice is also recorded in a poor state. In addition, users who do not want to record in the voicemail box may occur when the mobile communication terminal avoids the recording as described above. That is, there is a problem that waste of radio resources can be caused through the process of setting up and releasing unnecessary calls between the mobile communication terminal and the mobile communication system.

This will be described in more detail with reference to the drawings. 1 is a network diagram of a mobile communication terminal and a mobile communication system. Hereinafter, a network configuration and call setting of a mobile communication system will be described with reference to FIG. 1.

The mobile communication terminals are included in the areas of the base stations 1, 2, ..., 3 to communicate with the base stations wirelessly. Each of the base stations 1, 2,..., 3 is connected to base station system (BTS) 21,..., 22. That is, one or more base stations are connected to one control base station. Each control base station is connected to a mobile communication switching system. In FIG. 1, the control base station 21 is connected to the mobile communication switching system 30, and the control base station 22 is connected to the mobile communication switching system 32. Each of the mobile communication switching systems 30 and 32 includes a voice mailbox therein and visitor location registers (VLRs) 31 and 33 connected to the respective exchange systems. The switching systems 30, 32 are also connected to a Home Location Register (HLR) 40. Each of the mobile communication switching systems 30 and 32 is connected to a public switched telephone network (PSTN) 50. The operation according to this is as follows.

First, when the power of the mobile communication terminal is turned on, it transmits a signal according to the power-on to the corresponding base station. The base station then informs the mobile communication switching system via the control base station. Accordingly, the mobile communication exchange system registers the location of the mobile communication terminal in the visitor location register, and stores the state according to the location registration in the subscriber register 40. Through this, the mobile communication terminal is in a state capable of making and receiving calls. Therefore, when the call is received from the other mobile communication switching system or from the public network to the switching system in which the mobile communication terminal is registered, the call is received through the control base station and the base stations. In this case, the call is connected by the subscriber corresponding to the call acceptance, such as pressing a call key, opening a flip, or opening a folder, and communication is possible.

However, when the power of the mobile communication terminal is turned off, the mobile communication switching system connects the incoming call to a voice mailbox provided therein and informs the user that the power is off. The caller who wants to talk to the user of the mobile communication terminal can save and leave the voice message. In contrast, when the user does not receive the incoming call, the mobile communication switching system further checks that the position of the mobile communication terminal has been changed to further extend the calling range. Therefore, unnecessary radio resources are wasted, and at the same time, unnecessary operations are performed on the system side. This increases the load on the system.

As described above, the current mobile communication system and the mobile communication terminal have a problem of causing a waste of limited radio resources or increasing the price of the mobile communication terminal due to a problem in which a public place cannot be distinguished. In addition, when the power off, there was a problem that can not be received even if an urgent business call.

Accordingly, an object of the present invention is to provide a method for calling a mobile communication terminal in a mobile communication system and a mobile communication system that can store and receive a message received from a public place.

Another object of the present invention is to provide a method for calling a mobile communication terminal in a mobile communication system that can reduce the need for a call unnecessarily due to the user not responding to a call when the user of the mobile communication terminal is located in a public place.

Still another object of the present invention is to provide a method of calling a mobile communication terminal in a mobile communication system and a mobile communication system that can notify a user when an urgent message is received when a user of a mobile communication terminal is located in a public place.

The present invention for achieving the above object is a control method according to the incoming call when the state transition of the mobile communication terminal, when the call is received from the mobile communication system when the mobile communication terminal is in the etiquette state in response thereto Notify the system, and when a signal is received from the mobile communication system according to the storage of the message characterized in that notifying the user in a way except the audible sound.

The present invention for achieving the above object is a method for controlling the call in accordance with the state of the mobile communication terminal in a mobile communication system, the process of calling the mobile communication terminal when a call is received to a specific mobile communication terminal, and the mobile communication terminal When receiving the etiquette status message from the incoming call to the voice mailbox to store the message, and when the message storage of the incoming call is finished, sending a notification message to the mobile communication terminal do.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The same parts also use the same reference numerals, although shown in the other figures.

2 is a block diagram of a mobile communication terminal to which an embodiment of the present invention is applied. Hereinafter, the configuration of the mobile communication terminal and the operation according to the present invention will be described in detail with reference to FIG. 2. In addition, in the following description, a mode specifically performed in a mobile communication system and a mobile communication terminal according to the present invention will be described as an etiquette state.

The control unit 111 controls overall call operations, text data transmission and reception, and various operations according to various operations of the wireless terminal. In particular, the control unit 111 performs an etiquette state control according to the present invention. The radio unit 112 receives a signal transmitted over the air wave through the antenna ANT and outputs the signal to the controller 111 or to the voice processor 113. And the data received from the control unit 111 or the coded electrical voice signal received from the voice processing unit 113 is converted into a frequency of the transmission band and transmitted over the air through the antenna ANT. The voice processor 113 converts the coded voice signal received from the wireless unit 112 into an electric voice signal and outputs the converted voice signal to the speaker SPK. Then, the speaker SPK converts the electrical voice signal into an audible sound and outputs the audible sound. The microphone MIC converts the voice signal into an electrical signal and outputs the voice signal to the voice processor 113. Accordingly, the voice processor 113 codes the received signal and outputs the encoded signal to the wireless unit 112. The motor unit 114 operates the motor under the control of the control unit 111 as one means of informing an alarm when a call is received by the mobile communication terminal. The ringer unit 115 is another alarm means for notifying the incoming call by outputting a predetermined ring tone when the call is received by the control of the control unit 111. The memory unit 116 temporarily stores data necessary for control of the mobile communication terminal and data generated during control. Further, according to the present invention, the memory stores a data format for notifying the mobile communication system of the change of the etiquette state.

The key input unit 117 has a key matrix structure, and generates a key signal corresponding to a key input by the user and outputs the key signal to the control unit 111. In addition, the key input unit 117 according to the present invention is provided with a separate key for immediately switching to the attic mode or configured to operate simply by operating one key already in dual mode. In case of operating in dual mode, the key will be described as an example. When the input time of the key is longer than a predetermined time using the '*' key or '#' key, which is not used among the number keys provided for dialing, the state transition is performed. Can also be used as a signal that requires. The display unit 118 displays the current state and operation process of the mobile communication terminal under the control of the controller 111. In particular, the display unit 118 has a display function for informing the user when the etiquette is set in accordance with the present invention, and at the same time has a special means for displaying the received message during the etiquette state.

3 is a state transition diagram that a mobile communication terminal can have according to a preferred embodiment of the present invention. Hereinafter, each state and state transition process of the mobile communication terminal will be described in detail with reference to FIG. 3.

First, the activated state 200 is a state in which the power of the mobile communication terminal is turned on, and at the same time, when there is an incoming call from the base station, it is a state of informing the mode set by the user. Therefore, the call can be freely performed and at the same time, when the call is received, the call is notified by the state of the alarm set in the mobile communication terminal. That is, when the call is set when the vibration is set, the incoming call of the call will be notified by the vibration, and if the call is set to output the ringer sound is output to the ringer sound.

The etiquette state 210 refers to a state in which a call does not arrive by default as a state of transition by a user's key input. That is, in the case of A1 transitioning from the activated state 200 to the etiquette state 210, the mobile communication terminal sets a flag according to the etiquette state and stores the current state as an etiquette state. When the call is received in the etiquette state 210, the mobile communication system notifies the mobile communication system of a signal indicating that the state of the mobile communication terminal is the etiquette state 210. In addition, in the etiquette state 210, not only the transition to the power-off state 220, which is the process of (A2), but also the transition to the unreceived state 230, may be performed in the process of (A3). That is, the transition to the power-off state 220 is a process made by the user, and the transition to the radio wave non-received state 230 is an abnormal state where the transition is made when the radio wave is not reached from the base station.

The transition to the radio wave non-received state 230 may be made in any state, and is released when radio waves are normally received. The transition to the power off state 220 is also like this. The transition from the non-propagation state 230 or the power off state 220 to the etiquette state 210 is a case where a flag corresponding to the etiquette state is set.

4 is a control flowchart when the power of the mobile communication terminal is turned on according to a preferred embodiment of the present invention. Hereinafter, a process of transitioning between an activated state and an etiquette state will be described in detail with reference to FIGS. 2 to 4.

When the power supply is turned on, the control unit 111 of the mobile communication terminal proceeds to step 300 to perform an initialization operation of the wireless unit 112, the voice processing unit 113, the memory 116, and the like. In step 302, it is checked whether the current location of the mobile communication terminal is located in the radio wave reception area. If the control unit 111 is located in the test result radio wave receiving region of step 302, the control unit 111 proceeds to step 306 to perform a location registration process. However, if it is determined that it is not located in the radio wave reception area, the process proceeds to step 304 and transitions to the radio wave unreceived state 230 of FIG. 3, and performs the operation accordingly.

After performing the location registration in step 306, the controller 111 proceeds to step 308 to check whether the state before the power-off is activated. That is, it is checked whether the etiquette flag is set. As a result of the check, if the etiquette flag is set, the process proceeds to step 318; otherwise, the process proceeds to step 310. When the controller 111 proceeds to step 310, the controller 111 performs an operation according to the activation state 200. That is, an operation according to incoming and outgoing calls can be performed. In operation 312, the processor 110 determines whether the transition request signal is received in the etiquette state 210. If there is a transition request to the etiquette state, the controller 111 proceeds to step 318, and if not, proceeds to step 314.

When the controller 111 proceeds to step 314, the controller 111 determines whether a signal due to power off is received. If the control unit 111 receives a signal according to the power off, the control unit 111 proceeds to step 316, and otherwise performs step 310. When the controller 111 proceeds to step 316, the controller 111 notifies the mobile communication system of the power off through the base station, stops all the operations that are being performed, and ends.

On the contrary, when the process proceeds from step 308 or step 312 to step 318, the flag is stored in the etiquette state, and the display unit 118 indicates that the flag is in the etiquette state. In operation 320, an operation according to the etiquette state is performed. Here, the operation according to the etiquette state is the same as the etiquette state 210 of FIG. 3. In addition, the operation according to the detailed embodiment thereof will be described with reference to FIG. 5 to be described later.

When the controller 111 proceeds from step 320 to step 322, the controller 111 checks whether a signal for requesting a transition to the activated state is received from the key input unit 117. The control unit 111 proceeds to step 326 when requesting a transition to the activated state of the test result in step 322, and proceeds to step 324 to check whether the power is turned off. The control unit 111 proceeds to step 316 when the signal according to the power off is received in step 324. On the contrary, if the process proceeds from the step 322 to the step 326, the state transitions to the active state, the flag of the etiquette state is reset, and the display proceeds to the step 310 after displaying the flag.

5 is a control flowchart performed in an etiquette state according to a preferred embodiment of the present invention. Hereinafter, the control process in the etiquette state will be described in detail with reference to FIGS. 2 to 5.

The control unit 111 maintains the standby state in the etiquette state 210 in step 302a, and proceeds to step 320b to check whether a key signal according to a call request is received from the key input unit 117. If the key signal according to the call request is received in step 320b, the process proceeds to step 320h, otherwise proceeds to step 320c.

First, a case of calling request will be described. When the controller 111 proceeds to step 320c, the controller 111 performs the requested call operation, and proceeds to step 320d to check whether a link is formed. The control unit 111 proceeds to step 320f when the link is formed to perform the call mode, and when the end of the call is detected in step 320g, the controller 111 proceeds to step 320a to maintain the standby state. That is, as described above, the same process as the normal call is performed.

Next, when the control unit 111 proceeds to step 320h, it is checked whether the call is received through the wireless unit 112. If the incoming call is checked, the controller 111 proceeds to step 320i, otherwise proceeds to step 320j. When the controller 111 proceeds to step 320i, the controller 111 notifies the mobile communication system of the call response message indicating that the etiquette is in the mobile communication system, and then proceeds to step 320a. Here, if the form of the call response message is shown as shown in Table 1 below.

Item Remarks  IS-95 Page Message Fields  What Calling Messages in IS-95 Messages Have  Mobile Operation State  Operating state of the terminal (activation state = 0, etiquette state = 1)

The message indicating the operation state of the mobile communication terminal among the messages of Table 1 may inform the mobile communication system of each message of the terminal state. Therefore, since the state of the mobile communication terminal is an etiquette state, it informs the mobile communication system that the call mode cannot be performed. The mobile communication system then connects to the voice mail box, notifies the calling party that the mobile communication terminal is in an etiquette state, and induces recording of voice. This allows the caller to leave a message in the voice mailbox.

On the other hand, if the call result is not received in step 320h and proceeds to step 320j, it is checked whether a signal indicating that a voice message is stored is received from the mobile communication system. Such a message is called a notification message, and the form of the notification message may be configured as shown in Table 2 below.

Item Remarks  Mobile ID  Unique number required to recognize the terminal  Message ID  Indicates that this is a notification message  Sequency number  Message sequence number for detecting duplicate messages  Ack Request  Message requesting a reply  Encryption  Is the message secure?  Record Length  Indicates the length of the message delivered  Record  User message to forward

The message requesting a response among the notification messages of Table 2 may or may not be used. When sending a message requesting a response as described above, the mobile communication system may be configured to repeatedly send a message for a predetermined number of times until a notification response message according to the reception of the message is received from the mobile communication terminal. That is, when the response message is requested in this way, the notification response message may be configured as shown in Table 3 below.

Item Remarks  Mobile ID  Unique number required to recognize the terminal  Message ID  Message indicating that this is a notification response message  Sequency number  Number to detect duplicate messages

When receiving the notification response message as shown in Table 3, the mobile communication system determines that the message is normally delivered. Referring to FIG. 5 again, if the test result of step 320j is checked that the voice message is stored, the method proceeds to step 320k to notify that the call has been received by a method excluding audible sounds such as vibration. The controller 111 proceeds to step 320a to perform a standby mode according to the etiquette state 210. On the contrary, when proceeding from step 320j to step 320l, the controller 111 checks whether the control unit 111 moves to an unreceived radio wave area. If the control unit 111 moves to the radio wave non-receiving area, the control unit 111 proceeds to step 320m and transitions to the radio wave non-receiving state. Otherwise, the control unit 111 maintains the standby state of the etiquette state 210 of 320a.

Through this, when the mobile communication terminal is set to the etiquette state 210, whenever the incoming call is notified to the system to leave a message in the voice mailbox, the mobile communication system does not make unnecessary calls.

6 is a signal flow diagram between a mobile communication terminal and a mobile communication system according to a preferred embodiment of the present invention. Hereinafter, a signal flow between a mobile communication system and a mobile communication terminal will be described in detail with reference to FIGS. 1 to 6.

If the call is received in step 400, the mobile communication system proceeds to step 402 and transmits a call message to the primary area where the location of the mobile communication terminal is registered. If there is no response from the mobile communication terminal, the process proceeds to step 404. When the mobile communication system proceeds to step 404, the mobile communication system includes a primary area and transmits a call message to a secondary area, which is a larger area. When the mobile communication terminal receives the call message in step 402 or step 404, the mobile communication terminal proceeds to step 406 and transmits a call response message. The call response message accordingly is shown in Table 1 above. Also, according to the call message, a call response message for notifying that the state of the current mobile communication terminal is an etiquette state is transmitted to the mobile communication system. Accordingly, when the mobile communication system receives the call response message, it proceeds to step 408 to connect the calling party to the voice mailbox to store the message. When the storing of the message is ended, the process proceeds to step 410 and sends a notification message according to the storing of the message to the mobile communication terminal. When the mobile communication terminal receives the message, the mobile communication terminal proceeds to step 412 and delivers a notification response message to the mobile communication system. In operation 414, the mobile communication terminal notifies the user of the reception of the message through a method excluding an audible sound such as vibration.

As described above, when the mobile communication terminal is set to the etiquette state, the mobile communication terminal can recognize the state of the mobile communication terminal every time a call is received in the mobile communication system, thereby eliminating unnecessary calls. In addition, by having a message stored in a voice mailbox and notifying the mobile communication terminal there is an advantage that even if an urgent message is received in a public place can receive the message without disturbing others.
