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, a mobile phone is 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 described above, when the power of the mobile communication terminal is turned off.

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 such a case, there is a problem of making a call in a public place as described above. 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 automatically answering the mobile 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 has a voice mailbox therein, and has visitor location registers (VLRs) 31 and 33 connected to the respective switching 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 waste of radio resources is caused and unnecessary operation is performed on the side of the system. 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 mobile communication system and a method for calling a mobile communication terminal in a mobile communication system capable of confirming the call without receiving a call from a public place.                         

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 reduce the need for a call unnecessarily when a 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 call control method according to the state transition of the mobile communication terminal in the mobile communication system, the mobile communication system when a transition request signal to the etiquette state is received from the mobile communication terminal to the mobile communication system; Transitions the state of the terminal to the etiquette state according to the request of the etiquette state, and when a call is received in the etiquette state, connects to a voice mail box to notify the mobile communication terminal that the etiquette state is stored and saves the voice. If a signal indicating that a call has been received from the mobile communication system to the mobile communication terminal is received from the mobile communication system, the user is notified of the reception of the message using a method other than an audible sound. It is characterized by consisting of a process.

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. Then, 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 a transmission band and transmitted through the antenna ANT by airwaves. 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. In addition, according to the present invention, the memory stores a data format for informing 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 activation state 200 is a state in which the power of the mobile communication terminal is on, and at the same time, a state in which a signal received from a base station can be received. It also refers to a state that is not an etiquette state that is transitioned by a 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 is notified by the vibration, when the call is configured to output a predetermined ring tone is a state of outputting the ring tone.

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, when the transition from the activated state 200 to the etiquette state 210, the mobile communication terminal informs the mobile communication system of the signal according to the state transition. Then, when the call is received, the mobile communication system notifies the mobile communication terminal of only the data indicating that the call has been received without connecting it to the terminal. Therefore, the mobile communication terminal receives only a signal according to whether or not the call is received, and when receiving this signal, the user has received a call through a secondary method such as the motor unit 114 of FIG. Informing state. When the transition to the etiquette state 210, the display unit 118 of the mobile communication terminal indicates that the etiquette state (210). In addition, the transition from the etiquette state 210 to the activation state 200 may be operated by driving a key for transitioning to the etiquette state 210 provided in the key input unit 117 of the mobile communication terminal. In this case, the control unit 111 of the mobile communication terminal notifies a signal to the mobile communication system according to the message format according to the release of the etiquette state 210 stored in the memory 116. Through this, it is possible to transition from the etiquette state 210 to the activation state 200 again.

Next, the transition from the etiquette state 210 to the power off state 220 is a process that is performed only when the mobile terminal is powered off. That is, when the power of the mobile communication terminal is turned off, the mobile communication terminal notifies the mobile communication system of the signal according to the power off. Accordingly, the mobile communication system recognizes this and recognizes that the mobile communication terminal is in the power-off state 220. When the power is turned on again when the electronic device transitions from the etiquette state 210 to the power off state 220, the mobile communication terminal 220 performs only a process of registering a location according to the power on. Accordingly, the mobile communication terminal and the mobile communication system maintain the etiquette state 210.

If the power is turned off in the activation state 200, the power state transitions from the activation state to the power-off state 220. When the mobile communication terminal is powered on, the mobile communication terminal maintains an activated state 210 by performing location registration only.

The radio wave non-receiving state 230 is an operation performed on the assumption that the power of the mobile communication terminal is turned on. Occurs when the mobile communication terminal is located in a shaded area where radio waves cannot be received or in an area without a base station. Therefore, the transition from the power-off state to the radio wave not received state 230 is impossible. After the transition from the power-off state 220 to the power-on state, only the transition to the radio wave unreceived state 230 is possible. However, a transition from the radio wave not received state 230 to the power off state 220 is possible. This is only possible because the power is turned off by the user. In addition, the radio wave reception state may transition from the etiquette state 210 to the radio wave reception state 230 and the transition from the activated state 200 to the radio wave reception state 230. And the above reverse process is also possible.

4A and 4B are flowcharts illustrating operations of a state transition and a state transition in a mobile communication terminal according to an exemplary embodiment of the present invention. Hereinafter, a state transition process in a mobile communication terminal according to the present invention will be described in detail with reference to FIGS. 1 to 4A and 4B.

When the power of the mobile communication terminal is turned on, the control unit 111 performs an initialization operation of each block in operation 300. After performing such initialization, the control unit 111 proceeds to operation 302 to perform a wireless operation. The strength of the received field received from (112) is measured to determine if it is located in the radio wave reception area. The control unit 111 proceeds to step 304 if it is located in the test result radio receiving region, otherwise proceeds to step 306. In step 306, the control unit 111 transitions to the non-radio wave reception state of FIG. 3, and performs an operation for searching for radio waves received from the base station of the mobile communication system in the radio wave reception state. While performing this operation, the process proceeds to step 302 to continuously check whether radio waves are received. If radio waves are received in this process, the flow proceeds to step 304. The control unit 111 generates and outputs a signal for location registration to the mobile communication system in step 306. After performing the location registration in this way proceeds to step (308). When the controller 111 proceeds to step 308, the controller 111 checks the state table of the memory 116 to determine whether the state before the power of the mobile communication terminal is turned off is activated. If the previous state is the activated state as a result of the test, the control unit 111 proceeds to step 310 to maintain the activated state. However, if the previous state is not the active state, that is, the etiquette state proceeds to step 328.

First, when the controller 111 enters the activation state 200 of step 310, the controller 111 performs a basic operation of the mobile communication terminal. Here, the basic operation means performing an operation according to incoming and outgoing calls. In particular, when a call is received, the user is notified according to a preset method. That is, when the user sets the melody, when the call is received, the ringer unit 115 is driven to notify the user through a preset melody. When the user sets the melody, the user drives the motor unit 114 to notify it. While performing the basic operation, it is checked whether a key signal for requesting a transition from the key input unit 117 to the etiquette state 210 is received. When a key signal for requesting a transition to the etiquette state 210 is received from the key input unit 117, the control unit 111 proceeds to step 318 and requests for a transition to the etiquette state 210. If no key signal is received, the process proceeds to step 314.

In step 314, the controller 111 determines whether a key signal corresponding to a power off signal is received from the key input unit 117. If the key signal according to the power-off is received as a result of the test, the process proceeds to step 316, and if the key signal according to the power-off is not received, step 310 is performed. When the key signal according to the power off is received, the control unit 111 proceeds to step 316 and transmits a power off notification signal (Power Off Registration) to the base station of the mobile communication system and ends. By transmitting the power off notification signal to the base station, the mobile communication system detects that the state of the mobile communication terminal has transitioned to the power off state 220 of FIG. 3.

On the contrary, when proceeding from step 312 to step 318, the controller 111 reads a message format for notifying a transition to the etiquette state 210 from the memory 117 and transmits data accordingly. In this case, the message format of the transmitted data may be illustrated as shown in Table 1 below.

Message item Remarks Mobile ID Unique number required to recognize the terminal Message ID  Message used to transition between active state and etiquette state Sequence Number Sequence number to detect duplicate messages Ack Request Response request message Registration Mode How to register location of terminal in etiquette state Desired State Operation state to transition

In Table 1, the terminal ID is a number uniquely assigned to each terminal, and the message ID is a message for notifying that the message requires a state transition according to the present invention, and the sequence number is for preventing a message from being repeatedly transmitted and received. The message used. In addition, the response request is used when requesting a response to the message, and the registration mode is described in the form of a message provided according to the present invention to register a location in which the terminal operates in an etiquette state.

When performing location registration in the activated state 200, data of "0" is used, and when performing location registration in the etiquette state 210, data of "1" is used and location registration is not used. Use data of "2". Therefore, the data used in the registration mode can be composed of 2 bits. In addition, the transition state indicates an operation state to be transitioned. For example, the transition state uses “0” and the etiquette state uses “1”.

In addition, when the message as described above is transmitted, the mobile communication system transmits an acknowledgment message and needs a form of a message indicating that the mobile communication system is recognized according to the state requested by the mobile communication terminal. In the following description, such a message is referred to as a state transition message, and the state transition message may be illustrated as shown in Table 2 below.

Item Remarks Mobile ID Unique number required to recognize the terminal Message ID Message used to transition between active state and etiquette state Sequence Number Sequence number to detect duplicate messages Confirmed State Signal indicating the state to transition to Action time Visual information used to match state transition points

Referring to the contents of Table 2 that are not the same as in Table 1, the Confirmed State uses "1" to transition to the transition state, that is, the etiquette state, and "0" to transition to the active state. Can be used to make the transition. In addition, in order to match the timing of the state transition between the mobile communication terminal and the mobile communication system, it is configured to transition to the same state at the same time using Action Time information. As described above, the state transition confirmation message is used only when a message requesting a response to the state transition request message is used. Otherwise, the state transition confirmation message may be configured without the state transition confirmation message. However, etiquette status can only be trusted if both systems operate in the same mode, so it is recommended to use a state transition confirmation message.

As such, the control unit 111 increases the count CNT after transmitting a signal indicating a state transition. In operation 320, it is determined whether a response signal is received through the wireless unit 112. The control unit 111 proceeds to step 326 when a response signal is received, and proceeds to step 322 when a response signal is not received. The control unit 111 checks whether the value of the count CNT is equal to or greater than a predetermined value N in step 322. If the value of the test result count (CNT) is less than the set value, the control unit 111 proceeds to step 318, and if it is more than the set value, the control unit 111 proceeds to step 324 and displays a failure on the display unit 118. The value of the count CNT is reset.

Meanwhile, when receiving the response signal in step 320 and proceeding to step 326, the controller 111 resets the value of the count CNT and proceeds to step 328. The control unit 111 stores the current state in the status display table as an etiquette state 210 in the memory 116 in step 328, and then sends a message indicating that the display unit 118 has transitioned to the etiquette state 210. Display. The controller 111 maintains the etiquette state 210 in step 330. Here, the etiquette state 210 in the mobile communication terminal refers to a state of informing the vibration when there is an incoming call as described in FIG. That is, when a call is received, the mobile communication system connects the incoming call to the voice mailbox of the mobile communication system and stores the message. When the storage of the message is finished, only the signal for notifying the existence of the message is notified to the mobile communication terminal as a paging signal. Then, the mobile communication terminal refers to a state in which the mobile communication terminal notifies of this by a method other than a melody such as a vibration or a ringing tone. That is, it means to inform the state according to using the motor unit 114 of FIG. In addition, the operation for the call operates the same as the activation state (200).

The controller 111 performs the etiquette state 210 of step 330 and checks whether a key signal according to the power-off is received from the key input unit 117. When the key signal according to the power-off is received as a result of the test, the control unit 111 proceeds to step 316 described above. However, if the key signal according to the power-off is not received, the process proceeds to step 334 to check whether the state transition request signal is received. If the state transition request signal is received in step 334, the control unit 111 proceeds to step 336, otherwise, the control unit 111 maintains the etiquette state 210 of step 330. Here, the request for the state transition in the etiquette state 210 refers to a transition to the activated state 200, and the transition to the activated state 200 may be implemented by re-entering the same key as the transition to the etiquette state 210. It may also be configured to have a separate key for requesting a transition to the active state (200).

When the control unit 111 proceeds from step 334 to step 336, the controller 111 outputs a message requesting a transition to the torch state to the base station of the mobile communication system. At this time, the format of the output message may be configured in the same form as the message of Table 1. The controller 111 increases the value of the counter CNT. In step 328, the control unit 111 checks whether a response signal is received through the wireless unit 112. When the response signal is received from the wireless unit 112, the controller 111 proceeds to step 340 to reset the count value set in the count CNT, and proceeds to step 342. When the controller 111 proceeds to step 342, the controller 111 stores a message indicating a transition to the activated state in the memory 118 and then displays a message indicating the transition to the activated state on the display unit 118. Thereafter, the control unit 111 proceeds to step 310. However, if the response signal is not received in step 338, it is checked whether the value of the count CNT has a value greater than or equal to a preset value N. If the control unit 111 has a value equal to or greater than the preset value N, the controller 111 proceeds to step 346, otherwise, the controller 111 proceeds to step 336. Here, the preset value may use the same value when transitioning from the activation state 200 to the etiquette state 210 and when transitioning from the etiquette state 210 to the activation state 200 and may use different values. It may be. In the following description, it is assumed that the same value is used. When the value of the count CNT is greater than or equal to a preset value, the controller 111 displays a message indicating a failure in the state transition on the display unit 118 and then resets the value of the count CNT. do.

In describing the state transition of the mobile communication terminal in the above-described process, the state transition in other processes except for the description of the initial operation has not been described in the transition process to the radio wave unreceived state 230 of FIG. 3. However, when the state transition fails when the transition from the activated state 200 to the etiquette state 210 or the transition from the etiquette state 210 to the activation state 210 may be an un propagated state 230. However, the present invention is not limited thereto, and the above-described process may be performed when the radio wave condition is not good or when the mobile communication system is set to an overload state or a terminal which cannot transition to the etiquette state 210 in the mobile communication system. .

5 is a state transition diagram according to a state of a specific mobile communication terminal in a mobile communication system according to the present invention. Hereinafter, the state transition process of the mobile communication terminal in the mobile communication system and the operation of the mobile communication system according to the state transition will be described in detail with reference to FIG. 5.

The activation state 400 is a general state of each terminal, and refers to a state that can be performed without any obstacle to incoming and outgoing calls. The etiquette state 410 is a state according to the present invention, when a call is received by the mobile communication terminal in a mode of transition by a request from the mobile communication terminal, the switching system of the mobile communication system shown in FIG. Incoming call will be connected to the voice mailbox provided inside. In addition, according to the present invention, the voice mailbox informs the user that the user is not able to receive a call in a special situation, and induces the user to store the message. When a message is stored, data is transmitted to the control base station (BTS) in order to inform it of this. The corresponding control base station then transmits a notification message to each base station connected to the subordinate base station. Accordingly, the base station transmits a notification message to the mobile communication terminal to inform. In this case, the format of the notification message used may be illustrated in Table 3 below.

Item Remarks Mobule ID  Unique number of the terminal Message ID  ID to notify notification message Sequency number  Serial number to detect duplicate messages Ack Request  Message requesting a reply Encryption  Signal of encryption and security Record Length  Length of record to pass Record  Message from user forwarded

In the message of Table 3, the go number of the terminal and the ID of the message. Since the sequence number, response request, etc. are the same as described in Table 1, description thereof will be omitted. In addition, the encryption is a signal indicating that the transmission of the encrypted message when the security is required. In addition, the signal for the record length indicates the length of the record to be delivered, and the record is a message for notifying that there is a message input by the user or from the system in the etiquette state.

Then, the mobile communication terminal receiving the notification message is configured to notify the mobile communication system of the response message according to the notification. In this case, the notification response message may be shown in Table 4 below.

Item Remarks Mobile ID  Unique number of the terminal Message ID  ID to notify notification message Sequence Number  Serial number to detect duplicate messages

Since the messages shown in Table 4 are all the messages described in Tables 1 to 3, descriptions thereof will be omitted.

Next, the power-off state 420 will be described again with reference to FIGS. 4A to 4B. The power off state 420 transmits a signal (Power Off Registration) according to the power off when the mobile communication terminal turns off the power. When the signal according to the power-off is transmitted as described above, the mobile communication system stores the signal and becomes aware of the power-off state of the mobile communication terminal. The abnormal state 430 refers to a case in which a signal is not normally transmitted and received between the mobile communication system and the mobile communication terminal. In this case, when the mobile communication terminal is located in an area where radio waves are not received, or when the radio environment is poor, or when the call congestion and the system load are increased and the data is not normally processed from the mobile communication terminal, the mobile terminal is in an abnormal state 430. Process.

Next, the transition of states will be described. The mobile communication system immediately transitions to the power-off state 420 when the power-off signal of the mobile communication terminal is received in the activated state 400, and in this case, the mobile communication system transitions to the activated state 400. When the power is turned off in the etiquette state 410, the state transitions to the power off state 420. Then, when the power is turned on again, the state transitions to the etiquette state 410. In addition, the transition from the activated state 400 or the etiquette state 410 to the abnormal state 430 is accepted as the terminal transitioned to the abnormal state 430 as described in the abnormal state 430. When the signal is normally received again, it proceeds to the original mode. When the signal of the power off is received from the mobile communication terminal existing in the abnormal state 430, the process proceeds to the power off state 420, the location registration according to the power on from the mobile communication terminal in the power off state 420 Immediately after this, if the situation can be determined to be an abnormal state as described above, it is determined that the mobile communication terminal has transitioned to the abnormal state 430.

6 is a control flowchart illustrating a state transition in a mobile communication system by a request of a mobile communication terminal after location registration of the mobile communication terminal according to the present invention. Hereinafter, a state transition process in a mobile communication system will be described in detail with reference to FIGS. 1 and 6.

When the mobile communication system receives the power-on signal of the mobile communication terminal, the mobile communication system registers the location of the mobile communication terminal in step 500. And it checks the previous state of the mobile communication terminal. At this time, the previous state may be configured to be stored and registered in the switching system or subscriber register 40 of the mobile communication system. In addition, it may be configured to be stored and registered in both the exchange system and the subscriber register 40 of the mobile communication system. That is, when the mobile communication system is registered in the switching system of the mobile communication system, the mobile communication system can process the same. If the data exists in the subscriber register 40, the previous state is checked with reference to the data.

After checking the previous state as described above, if the previous state exists in the active state 400, the process proceeds to step 504; otherwise, if it exists in the etiquette state 410, the step (512). Proceed to When the mobile communication system proceeds to step 504, it maintains an activated state (400). Here, the activated state 400 is the same state as described above with reference to FIG. 5, and the routine according to this is described with reference to FIG. 7. The mobile communication system checks whether a state transition request message is received from the mobile communication terminal while maintaining the activation state 400. At this time, the type of message received from the mobile communication terminal is a message as shown in Table 1 above. The mobile communication system proceeds to step 510 when the test result state transition request signal is received, and otherwise proceeds to step 508. When the mobile communication terminal proceeds to step 508, it checks whether a signal according to the power-off is received from the mobile communication terminal. If the test result is received from the mobile terminal according to the power off proceeds to step 518, otherwise proceeds to step 504.

On the other hand, if the process proceeds from step 508 to step 510, the mobile communication system notifies the mobile terminal through the base station through the corresponding response signal and changes the state. In this case, the change of the state is to change the state of the mobile communication terminal to an etiquette state and store the mobile communication system only when the mobile communication system is configured to know the mobile communication system, and the subscriber register 40 knows this. Data is stored in subscriber register 40. In operation 512, the etiquette state 410 is performed. The control flow of the mobile communication system performed in the etiquette state 410 will be described in detail later with reference to FIG. 8.

As described above, the mobile communication system performs the etiquette state 410 in step 512 and proceeds to step 514 to check whether a state transition request signal is received from the mobile communication terminal. The mobile communication system proceeds to step 520 when the state transition request signal is received through the base station to the mobile communication switching system. Otherwise, the mobile communication system proceeds to step 516 to check whether the power-off signal is received. When the power-off signal is received, the mobile communication system proceeds to step 518 and sets a bit informing the mobile communication system that the mobile communication terminal is in a power-off state to register the power-off and ends.

On the contrary, in step 514 to step 520, the mobile communication system transmits a response signal to the mobile communication terminal through the corresponding base station. Then, the data according to the state change is stored in the mobile communication switching system and the subscriber register 40 according to the state. Through this, the activation state 400 and the etiquette state 410 may be maintained in the mobile communication system according to the activation state 200 or the etiquette state 210 of the mobile communication terminal, and the call may be processed accordingly.

7 is a control flowchart of an activation state of a mobile communication terminal in a mobile communication system. Hereinafter, a control flow according to an activation state of a terminal in a mobile communication system will be described in detail with reference to FIGS. 1 to 7.

When the mobile communication terminal enters an activated state, the exchange system of the mobile communication system first checks a voice mail system (VMS) in step 504a. The flow proceeds to step 504b to check whether there is an unsent message. The mobile communication switching system proceeds to step 504c if an unsent message exists in the voicemail box, and proceeds to step 504d if an unsent message does not exist. In step 504c, the exchange system of the mobile communication system transmits an unsent message to the mobile communication terminal using a base station where the mobile communication terminal is located. The flow proceeds to step 504d to maintain the standby state. The mobile communication system maintains the standby state in step 504d, and proceeds to step 504e to check whether a call is required from the mobile communication terminal. If the above call result is called, the process proceeds to step 504f. Otherwise, the process proceeds to step 504i. In step 504f, the mobile communication switching system performs an operation according to a request of the mobile communication terminal. That is, when a data service is requested, an operation of a call according to the data service is performed, and when a service of a voice call is requested, an operation of a call according to the voice call is performed. Thereafter, the process proceeds to step 504g to perform a call mode corresponding thereto. In step 504h, it is checked whether the call is terminated. If the call is terminated as a result of the test, the process proceeds to step 504d. If the call does not end, the process proceeds to step 504g.

In contrast, if the mobile communication switching system proceeds to step 504i, it checks whether a call is received by the mobile communication terminal. If the call is received as a result of the check proceeds to step (504j), if the call is not received proceeds to step (504d). If the mobile communication switching system proceeds to step 504j, the mobile communication switching system performs a transmission mode according to a call reception. In this case, the transmission mode according to the call reception refers to transmitting a signal according to the call reception through the base station where the mobile communication terminal is expected to be located in the mobile communication switching system. As shown in FIG. The process of expanding the world. In operation 504k, the mobile communication switching system checks whether there is a response from the mobile communication terminal. The mobile communication switching system proceeds to step 504n if there is a response from the check result of step 504k, and proceeds to step 504l if there is no response. The mobile communication switching system checks whether the time set in step 504l has elapsed. This checking of the elapse of the set time is to efficiently manage the resources of the radio channel, and to set up to deliver the message through the voice mailbox when there is an incoming call. The mobile communication switching system proceeds to step 504m when the set time has elapsed, and proceeds to step 504j when the set time has not elapsed. When the mobile communication switching system proceeds to step 504m, the mobile communication switching system processes the abnormal state 430 and connects a call to a voice mail box provided in the mobile communication switching system to inform that the user cannot connect.

On the contrary, when the response signal is received and proceeds to step 504n, the call and the incoming call mode are performed. The method proceeds to step 504o to check whether the call is terminated. The mobile communication switching system proceeds to step 504d, where the call is terminated, and continues to step 504n.

8 is a control flowchart of an etiquette state in FIG. 6 according to the present invention. Hereinafter, a control process in an etiquette state according to the present invention will be described in detail with reference to FIGS. 1 to 8.

When entering the etiquette state, the mobile communication switching system proceeds to step 512a to check the voicemail box. In step 512b, it is checked whether there is an unsent message. If there is an unsent message according to the result of the check, the process proceeds to step 512e and transmits the unsent message through the corresponding base station of the mobile communication system, and then proceeds to step 512d. If yes, go to step 512d. The mobile communication switching system proceeds to step 512d to maintain a standby state for checking whether incoming and outgoing request signals of a call are received. Therefore, the mobile communication switching system proceeds to step 512e to check whether the mobile communication terminal receives a call request signal through the base station. In the etiquette state 410, the mobile communication exchange system does not limit the call. Therefore, when the call request signal is received, the mobile communication exchange system proceeds to step 512f. The mobile communication switching system performs an operation according to the request of the mobile communication terminal in step 512f. In operation 512g, the call mode is performed. That is, a call of the type required by the mobile communication terminal is performed. The mobile communication exchange system performs the call mode of step 512g and proceeds to step 512h to check whether the call is terminated. If the call is terminated as a result of the check proceeds to step (512d), if the call is not terminated continues to (512g).

On the contrary, there is no call request and the call is checked in the etiquette state 410. When the call is received, the mobile communication switching system proceeds to step 512j. Otherwise, the mobile communication switching system performs step 512d. The mobile communication switching system connects the incoming call to the voicemail when the call is received as a result of the check in step 512i and proceeds to step 512j. After controlling the voicemail box, the mobile communication terminal is in a state of quietness, so a message indicating that the call cannot be connected is notified to the caller and proceeds to step 512k to store the message received from the calling party in memory. . When the storage of the message is terminated as described above, the process proceeds to step 512l and a message notification signal is transmitted to the base station where the mobile communication terminal exists. At this time, the type of the message to be transmitted is informed in the format of the message shown in Table 3. This informs the mobile terminal that the message has been received.

9 is a signal flowchart of a state transition between a mobile communication terminal and a mobile communication system according to an exemplary embodiment of the present invention. Hereinafter, a process of state transition between a mobile communication terminal and a mobile communication system according to the present invention will be described in detail with reference to FIGS. 1 to 9.

The mobile communication terminal transmits a state transition request message to the mobile communication system in step 602 when a key signal for requesting a state transition is input by the user in step 600. In this case, the message transmitted from the mobile communication terminal to the mobile communication system is a message shown in Table 1 above. Then, the message transmitted from the mobile communication terminal is delivered to the mobile communication switching system through the base station and the control base station of the mobile communication system. When the message is transmitted as described above, the mobile communication exchange system controls the control base station and the base station in response to the transmission of the state transition confirmation message. In step 604, the base station of the mobile communication system transmits a state transition confirmation message to the mobile communication terminal. This is a message as shown in Table 2 above. Through this, the mobile communication terminal transitions to the state requested by the user in step 606. That is, when the current state is the activated state 200, the state transitions to the etiquette state 210, and when the current state is the etiquette state 210, the state transitions to the activated state 200. In operation 608, the mobile communication switching system performs a state transition. Since the mobile communication exchange system also recognizes the state of the mobile communication terminal together, when the existing state is the activated state 400, the mobile communication exchange system transitions to the etiquette state 410 and stores the state. The existing state is the etiquette state 210. ) Transitions to the activated state 400.

10 is a signal flowchart for informing the mobile communication terminal of the call when the call is received by the mobile communication terminal in the etiquette state according to the present invention. Hereinafter, a process of notifying that a call is received by the mobile communication system when the mobile communication terminal is in the etiquette state 200 will be described in detail with reference to FIGS. 1 to 10.

When the location registration is performed in step 610 and the current state is the etiquette state 200, the mobile communication system also recognizes the state of the mobile communication terminal as the etiquette state 400. In this case, when a call requesting a voice call with the mobile communication terminal having the etiquette state 400 is received at the exchange system side of the mobile communication system in step 612, the mobile communication exchange system calls the call to the voicemail box in step 614. Connect. The voicemail box is controlled as described above to induce the caller to store the message. When the message is stored through this process, the exchange system of the mobile communication system proceeds to step 616 to control the control base station and the base station to transmit a signal indicating that the call is received. The format of the transmitted message is as described in Table 3 above. These messages are delivered wirelessly from the base station to the mobile communication system. However, if a response signal is not received from the mobile communication terminal, the call range is further extended to attempt a second call. In this case, the type of the message output wirelessly from the base station is as shown in Table 3 above, and only allows the message to be transmitted through more base stations. Then, when the call signal is received, the mobile terminal notifies that the message is received by a method other than an audible sound such as a melody or a ringing bell. The mobile communication terminal then transmits a response signal to the mobile communication system. At this time, the type of the message to be transmitted is output as a message of the form shown in Table 4 above.

Through this process, the person who owns the mobile communication terminal does not have inconvenience or direct calls to the surrounding people even when a call is received in a place requiring quietness or waiting for an urgent call. The advantage is that you can receive the message without making your back sound.
