Description

  The present invention relates to a mobile terminal that notifies that a call is disconnected when a predetermined call restriction area is entered.

  In general, in areas where the use of mobile terminals should be prohibited (hospitals, airplanes, etc.), the mobile terminals are forcibly notified by sending a control (power-off) message to turn off the mobile terminals. A technology for prohibiting communication such as outgoing and incoming calls has been invented and is going to be realized in the future.

  When a mobile device is powered off in a power-off area, notifying a third party that the mobile device cannot be used identifies the reason why the notified third party cannot contact There is an advantage that it is possible to save the trouble of repeatedly making a call. As a technique for notifying a third party that a mobile terminal has been powered off in a power-off area, there is a technique disclosed in Patent Document 1.

  In the technique shown in Patent Literature 1, gates arranged in a call prohibition area and information related to the call prohibition area are registered in the database of the base station. When one mobile radio terminal passes through the gate arranged in the call prohibition area, the gate transmits a power OFF setting to the one mobile radio terminal, and receives the telephone number information of the mobile radio terminal received from the one mobile radio terminal. Send to base station. The base station registers the telephone number received from the gate in association with the gate. When a user makes a call from another mobile radio terminal to one mobile radio terminal, the base station confirms that the one mobile radio terminal is currently in the call prohibition area and is in a power-off state. Without accessing the terminal, the user is notified of information on the call prohibition area where one mobile radio terminal is located.

(First embodiment of the present invention)
(1. System configuration)
FIG. 1 is a system configuration diagram when a power-off notification is performed using the mobile terminal according to the present embodiment. The system 1 includes radio control apparatuses (hereinafter referred to as RNC) 110a to 110n and base stations 120a to 120n. Each RNC manages an area composed of a plurality of cells, and each base station manages each cell.

In FIG. 1, it is assumed that the area of cell b is an area where communication functions are restricted such as a hospital or a movie theater. User A has a mobile terminal 130a, and call partner B has a mobile terminal 130b. Then, the user A moves from the cell a to the cell b while talking with the call partner B. The base station 120b transmits a control message to the mobile terminal 130a by a cell broadcast method (details are omitted because it is a well-known technique) that can simultaneously distribute messages to mobile terminals in a certain area. The mobile terminal 130a is instructed to be turned off. The mobile terminal 130a that has received the control message transmits a notification to the effect that the call is disconnected to the mobile terminal 130b and disconnects the power supply (call).
Here, the user A moves the cell while making a call, but it is not necessary to make a call. In that case, of course, the call is not disconnected.

  Further, the method for detecting the movement of the user A from the cell a to the cell b is not limited to the cell broadcast method. For example, you may detect having moved to the cell b by providing the mobile terminal 130a with a GPS function. Further, assuming that the radio wave of cell a is s1 and the radio wave of cell b is s2, mobile terminal 130a is detected when a change in radio wave intensity such as s1 >> s2-> s1> s2-> s1 = s2-> s1 <s2 is detected. May be determined to have moved from cell a to cell b. In this case, it is not necessary to receive a control message from the base station, and the mobile terminal 130a can recognize that it has moved to the cell b.

(2. Module configuration)
FIG. 2 is a module configuration diagram of the mobile terminal according to the present embodiment. The mobile terminal 130a includes a wireless processing unit 205, a transmission / reception control unit 210, a message analysis unit 215, a power-off control unit 220, a call control unit 225, a call disconnection notification control unit 230, and a call disconnection notification generation unit. 235, a call disconnection notification setting unit 240, a power supply control unit 245, and a call disconnection notification information DB 250.
The wireless processing unit 205 performs transmission / reception processing of wireless signals with the base stations 120a to 120n.

  The transmission / reception control unit 210 performs a process of making a transmission request to the wireless processing unit 205 in response to a data transmission request from a higher function. In addition, the transmission / reception control unit 210 performs processing for passing the reception data received from the wireless processing unit 205 to the message analysis unit 215. Further, when receiving a call disconnection notification transmission request from the call disconnection notification control unit 230, the transmission / reception control unit 210 sends a call disconnection notification transmission request to the wireless processing unit 205 and disconnects the call to the call disconnection notification control unit 230. Processing to send a notification transmission completion notification is performed.

  The message analysis unit 215 analyzes the data received from the transmission / reception control unit 210, and performs processing for notifying the power-off control unit 220 of the power-off message if the data is a power-off message sent from the base station.

When the power-off control unit 220 receives a power-off message from the message analysis unit 215, the power-off control unit 220 performs a process of requesting the call control unit 225 to search whether there is a call in progress. When there is a call in progress, the power-off control unit 220 transmits a call disconnection notification request to the call partner to the call disconnection notification control unit 230. When there is no call in progress, a power-off request is transmitted to the power control unit 245.
In response to a call call search request from the power-off control unit 220, the call control unit 225 performs a process of searching for a call in progress and returning the result to the power-off control unit 220.

  When the call disconnection notification control unit 230 receives a call disconnection notification request from the power disconnection control unit 220, the call disconnection notification control unit 230 performs a process of requesting the call disconnection notification generation unit 235 to generate a call disconnection notification. When a message is generated by the call disconnection notification generation unit 235, a call disconnection notification transmission request is sent to the transmission / reception control unit 210.

  The call disconnection notification generation unit 235 receives the call disconnection notification generation request from the call disconnection notification control unit 230, acquires the call disconnection notification information of the call partner from the call disconnection notification information database (call disconnection notification information DB) 250, A process for generating a call disconnect notification message is performed. At this time, if the call partner is associated with a message created in advance, a message corresponding to the call partner is generated.

  The call disconnection notification setting unit 240 registers the call disconnection notification information in the call disconnection notification information DB 250 when registering a notification message for each call partner in response to a request from the user.

The power control unit 245 receives the power cut request from the power cut control unit 220 and performs a power cut process.
The call disconnection notification information DB 250 is a database that stores a call disconnection notification message. A common message may be stored in association with all persons who make notifications, or different messages may be stored in association with persons who make notifications.

  Even when there is no call in progress, a call disconnection notification request may be made to the call disconnection notification control unit 230. By doing so, even when the mobile terminal moves to an area where the communication function is restricted when it is not in a call, a notification to that effect can be transmitted to the mobile terminal registered in the call disconnection notification information DB 250 in advance. it can.

(3. Operation)
FIG. 3 is a sequence diagram showing the operation of the mobile terminal according to the present embodiment. Here, it is assumed that the user A of the mobile terminal 130a who is talking with the call partner B in FIG. 1 enters the power-off area (cell b) while talking. At this time, the call control unit 225 of the mobile terminal 130a of the user A holds a call state (a state in which a call is being made and a telephone number of the other party is held).

  By entering the cell b, the mobile terminal 130a of the user A receives the power-off message from the base station 120b. In the mobile terminal 130 a, if the message received via the wireless processing unit 205, the transmission / reception control unit 210, and the message analysis unit 215 is determined to be a power-off message by the message analysis unit 215, the power-off control unit 220 Power off notification is forwarded.

  When the power-off control unit 220 receives the power-off notification, the power-off control unit 220 requests the call control unit 225 to search whether there is a call in progress. The call control unit 225 refers to the held call state and returns the telephone number (090-XXXX-XXXX) of the communication partner B to the power-off control unit 220. The power-off control unit 220 makes a call disconnection notification request to the call disconnection notification control unit 230 when there is a call in progress. Further, when there is no other party in the call (when the user A and the other party B are not in a call), the power supply control unit 245 is requested to turn off the power, and the power supply control unit 245 starts the power-off process. To do.

  The call disconnection notification control unit 230 makes a call disconnection notification generation request to the call disconnection notification generation unit 235. At that time, the telephone number of the other party B is also given. The call disconnection notification generation unit 235 searches the call disconnection notification DB 250 using the telephone number of the communication partner B (090-XXXX-XXXX) as a key. After searching the call disconnection notification DB 250, a call disconnection notification is transmitted to the call partner B. In the present embodiment, as a method for transmitting a call disconnection notification, there is SMS (short message service) or mail transmission by packet communication.

(3-1 Contents of database)
Here, determination of the call disconnection notification information DB 250 and the call disconnection notification transmission method will be described. FIG. 4 is a diagram illustrating an example of the contents of the call disconnection notification information DB 250. FIG. 4A shows a configuration in the case where a notification message is transmitted in common regardless of the notification partner. In this case, the call disconnection notification information DB 250 has at least a telephone number and an e-mail address, preferably a name. FIG. 4B shows a configuration when different notification messages are transmitted in association with the notification partner. In this case, the item of the disconnection notification content number is added, and the disconnection notification content table is separately held.
Note that it is not always necessary to separately hold the disconnect notification content table, and the item of the disconnect notification content number may be used as the disconnect notification content item.

(3-2 Database registration and creation)
Registration and creation of the notification message in FIG. 4B will be described in more detail. In FIG. 2, the notification message is registered through the user interface, and when the message is created, the call disconnection notification setting unit 240 is notified. The call disconnection notification setting unit 240 registers a message to be registered in the “disconnection notification content table” in the call disconnection notification DB 250 as the disconnection notification content. The disconnect notification content table manages the disconnect notification content number as an index, and a plurality of messages can be registered. After registering the message in the “disconnection notification content table”, the user A associates the created message with the call partner. In this embodiment, a disconnection notification content number item is newly provided, and the disconnection notification content number of the “disconnection notification content table” is set in this item to associate them. Here, when the disconnection notification content number = 1, it is handled as a default, and when no number is stored in the disconnection notification content number field, it is notified as a default. The call partner B is assumed to be a user corresponding to “△△ Δ △” in index 2 of FIG. 4B, and the call is established with the message registration and association already made with the disconnected call content number = 2. Assume that When the user A of the mobile terminal 130a moves to the cell b during a call, the call disconnection notification control unit 230 makes a call disconnection notification generation request to the call disconnection notification generation unit 235. At that time, the telephone number of the communication partner B is handed over. The call disconnection notification generation unit 235 searches the call disconnection notification DB 250 using the telephone number (090-yyyy-yyyy) of the other party B as a key. Here, the telephone number (090-yyyy-yyyy) of the calling party B exists in the call disconnection notification information DB 250 and the disconnection notification content number = 2 is set. By referring to the table, it is possible to obtain a disconnection notification message (here, “I will reconnect later because of the power-off area”) corresponding to the call partner B.

(3-3 Determination of transmission method)
(3-3-1 When messages are common)
FIG. 5 is a flowchart for determining a method for transmitting a call disconnection notification in the data configuration in the case of FIG. First, a telephone number during a call is acquired as identification information (step S501), and the call disconnection notification DB 250 is searched (step S502). Next, a disconnection notification message is acquired (step S503). It is determined whether the telephone number is registered in the call disconnection notification DB 250 (step S504), and if not registered, an SMS is created (step S507). If registered, it is determined whether or not the mail address information of the calling party B is stored (step S505), and if not stored, an SMS is created (step S507). If stored, a mail for packet communication is created (step S506). When SMS or mail is created, the call disconnection notification control unit 230 is called (step S508), and the process is terminated.

(3-3-2 When messages are not common)
FIG. 6 is a flowchart for determining a method for transmitting a call disconnection notification in the data configuration in the case of FIG. First, a telephone number during a call is acquired as identification information (step S601), and the call disconnection notification DB 250 is searched (step S602). Next, it is determined whether or not the telephone number is registered in the call disconnection notification DB 250 (step S603). If not registered, a disconnection notification message is acquired with the disconnection notification content number as an initial value (= 1). (Step S609), an SMS is created (Step S610). If registered, the disconnection notification content number is acquired (step S604), the disconnection notification content table is searched using the acquired disconnection notification content number as a key (step S605), and the disconnection notification message is acquired (step S606). ). It is determined whether or not the information of the mail address of the other party B is stored (step S607). If not stored, an SMS is created (step S610). If stored, a mail for packet communication is created (step S608). When SMS or mail is created, the call disconnection notification control unit 230 is called (step S611), and the process is terminated.

  That is, in the case of FIG. 4B, if the user corresponding to “ΔΔ ΔΔ” is the call partner B, the mail address of B is not registered, and therefore SMS is selected as the transmission method here. The call disconnection notification generation unit 235 creates an SMS with the content of destination = phone number, text = (“return to power supply because of power-off area”), and returns a response to the call disconnection notification control unit 230.

Up to this point, the call disconnection notification information DB 250 and the determination of the call disconnection notification transmission method have been described.
Note that message registration is not necessarily performed by the user, and a fixed message may be registered in the terminal in advance. In that case, the call disconnection notification setting unit 240 in FIG. 2 is not necessarily an essential component.

  Returning to FIG. 3, when the transmission method is determined, the call disconnection notification generation unit 235, for example, the destination = XXX @ abc. com, body = “call cut due to power-off area” is created, and a call disconnection notification generation completion notification is transmitted to the call disconnection notification control unit 230. The content of the text may be different for each person to be notified. When the call disconnection notification control unit 230 receives the call disconnection notification generation completion notification from the call disconnection notification generation unit 235, it makes a call disconnection notification transmission request to the transmission / reception control unit 210. The transmission / reception control unit 210 transmits a call disconnection notification to the other party in accordance with the transmission format. When the transmission is completed, the transmission / reception control unit 210 transmits a call disconnection notification transmission completion notification to the call disconnection notification control unit 230, and the call disconnection notification control unit 230 transmits a call disconnection notification completion notification to the power disconnection control unit 220. The power-off control unit 220 issues a power-off request to the power supply control unit 245, and the power supply control unit 245 starts a power-off process.

  Note that, as described above, even when there is no call, the call disconnection control unit 220 may make a call disconnection notification request to the call disconnection notification control unit 230. In that case, the other party who performs the call disconnection notification may be determined based on the information stored in the call disconnection notification information DB 250, or may be notified to the other party arbitrarily set in advance by the user. Also good.

  With the above mechanism, the mobile terminal 130a entering the cell b during a call can be turned off after transmitting a call disconnection notification to the call partner B. The mobile terminal 130b that has received the call disconnection notification can receive the call disconnection notification by a general SMS or mail function, and can grasp that the call has been disconnected because the user A has moved to the power-off area.

  Although the present embodiment uses a power-off instruction from the network as a trigger, the call is similarly disconnected by an instruction to shift to the self-mode (mode that disables all functions that require communication) by cell broadcast. Application is possible even in such a case.

  Thus, according to the mobile terminal according to the present embodiment, in order to notify the other mobile terminal of the notification when entering the call restriction area, the other mobile terminal that has received the notification The owner can grasp in advance that the telephone will not be connected, and can save the trouble of making a useless call.

In addition, if you enter the call restriction area during a call, the call state is stopped and the other party is notified, so even if the call suddenly breaks, the other party prohibits the call from being interrupted It is possible to grasp that it is due to entering the area, and it is possible to save the trouble of repeating the connection until it is connected many times in order to identify the cause.
Further, since the notification content is selected according to the partner notified by the notification means, it is possible to respond by notifying an appropriate message according to the attribute of the partner.

(Second embodiment of the present invention)
The second embodiment of the present invention will be described below. Here, when the user A enters the power-off area (cell B), a message is transmitted to the mobile terminal 130b of the communication partner B, and a notification that the user terminal 130a has entered the power-off area is also sent. It can be carried out.
(1. Configuration)
FIG. 7 is a module configuration diagram of the mobile terminal according to the present embodiment. The difference from the first embodiment is that a display control unit 260 is provided.
The display control unit 260 receives a display request from the call disconnection notification control unit 230 based on the call disconnection notification transmission completion notification received by the call disconnection notification control unit 230, and the mobile terminal 130a enters the power disconnection area. A process for controlling the display of the notification to the effect is performed.

(2. Operation)
FIG. 8 is a sequence diagram showing the operation of the mobile terminal according to the present embodiment. The difference from the first embodiment is that the call disconnection notification control unit 230 that has received the call disconnection notification transmission completion notification issues a call disconnection completion notification to the power supply disconnection control unit 220 and at the same time displays a request to the display control unit 260. This is the point of notification (process A portion in FIG. 8). Upon receiving the display request notification, the display control unit 260 displays a message indicating that it has entered the power-off area on the display screen of the mobile terminal 130a.

  As in the case of the first embodiment, the message indicating that the power-off area has been entered is registered in advance in the call disconnection notification information DB 250 and acquired at the same time as the call disconnection message is acquired. Alternatively, the message may be acquired by reading the call disconnection notification information DB 250 immediately before notifying the display request.

Further, the message indicating that the power-off area has been entered may be freely registered from the user interface as in the case of the first embodiment.
Furthermore, the user may arbitrarily set whether or not to display a message to the effect that he / she has entered the power-off area on his / her own terminal (here, user A's terminal 130a).

  Thus, according to the mobile terminal according to the present embodiment, when entering the call restriction area, to notify other mobile terminals and the own terminal that has entered the call restriction area to that effect The other party can understand why the call was interrupted, and at the same time, the user can understand why the call was interrupted. it can.

(Third embodiment of the present invention)
The third embodiment of the present invention will be described below. Here, a process when user A once enters the power-off area and then comes out of the power-off area and can talk again will be described.
(1. Configuration)
FIG. 9 is a module configuration diagram of the mobile terminal according to the present embodiment. The difference from the first or second embodiment is that a power ON control unit 220a, a call enable notification control unit 230a, and a call enable notification generating unit 235a are provided.

  When the power-on control unit 220a receives the power-on notification transmitted from the power control unit 245, the power-on control unit 220a performs a process of notifying the power-off control unit 220 of a call disconnecting call search request. The power-off control unit 220 searches the call history information stored in the call disconnection notification information DB 250. As a result, if the reason for the disconnection of the call is due to the entry into the power-off area, a call enable notification A callable notification request is transmitted to the control unit 230a.

  When the call enable notification control unit 230a receives a call enable notification request from the power ON control unit 220a, the call enable notification generation unit 235a performs a process of making a call enable notification generation request. When the message is generated, a callable notification transmission request is sent to the transmission / reception control unit 210.

In response to the call enable notification generation request from the call enable notification control unit 230a, the call enable notification generating unit 235a acquires the call enable notification information of the call partner from the call disconnect notification information DB 250, and generates a call enable notification message. Process. At this time, if the call partner is associated with a message created in advance, a message corresponding to the call partner is generated.
Since other components are the same as those in the first or second embodiment, the description thereof is omitted.

Note that it is assumed that not only a message at the time of disconnection but also a message at the time of communication possible (callable notification information) is registered in the call disconnection notification information DB 250 in advance.
In addition, the power ON control unit 220a and the power cutoff control unit 220, the call enable notification control unit 230a and the call disconnection notification control unit 230, and the call enable notification generation unit 235a and the call disconnection notification generation unit 235 are integrally configured. It may be taken as.

(2. Operation)
FIG. 10 is a sequence diagram showing the operation of the mobile terminal according to the present embodiment. Here, since the user A enters the power-off area (cell B) while the user A and the other party B are talking, the power (call) is temporarily disconnected, and then the user A leaves the power-off area. It is assumed that a call can be made. First, the user A recognizes that he / she has left the power-off area and turns on the mobile terminal 130a. Specifically, a power-on detection unit provided in the power control unit 245 detects a long press of the power key to detect power-on, and when the power-on detection unit detects power-on, the power control unit 245 Sends a power-on notification to the power-on control unit 220a. The power-on control unit 220a transmits a call disconnection call search request to the power-off control unit 220 in order to check whether there is a call that has been disconnected due to entering the power-off area. To do. The power-off control unit 220 that has received the disconnected call search request during a call stores whether or not there is a call that has been disconnected because it has entered the power-off area. And a call disconnection call search request response is returned to the power ON control unit 220a.

  The power-on control unit 220a that has received the disconnection call search request response during a call performs normal startup processing together with the power control unit 245 when there is no call that has been disconnected due to entering the power-off area. To do. The normal start-up process here is a process for bringing the mobile terminal 130a into an activated state. Specifically, without performing a process for notifying other mobile terminals that the mobile terminal 130a has been exited, This is a process of making a state where transmission (transmission) is possible and a state where reception (reception) is possible.

  If there is a call that has been disconnected due to entering the power-off area, the power-ON control unit 220a transmits a call-enabled notification request to the call-enabled notification control unit 230a. Upon receiving the call enable notification request, the call enable notification control unit 230a transmits a call enable notification generation request to the call enable notification generating unit 235a. The callable notification generation unit 235a that generated the message returns a callable notification generation completion notification to the callable notification control unit 230a.

The call enable notification control unit 230a receives the call enable notification generation completion notification and transmits a call enable notification transmission request to the transmission / reception control unit 210. The transmission / reception control unit 210 transmits a call-capable notification transmission request to the wireless processing unit 205, and a message indicating that a call is possible is transmitted from the wireless processing unit 205 to the mobile terminal 130b possessed by the communication partner B. At the same time, a call enable notification transmission completion notification is transmitted to the transmission / reception control unit 210, and the process is terminated.
With the above mechanism, the mobile terminal 130a that has left the power-off area can notify the mobile terminal 130b of the other party B that it is possible to make a call again.

Thus, according to the mobile terminal according to the present embodiment, when the mobile terminal leaves the call restriction area, the mobile terminal is restarted, and the restart process is used as a trigger for the mobile terminal. In order to notify the other mobile terminal that the terminal is out of the call prohibition area, the owner of the other mobile terminal that has received the notification may recognize that the call can be resumed. it can.
In addition, since it is possible to grasp that the call is restricted until the notification is received, it is possible to save the trouble of making a useless call during that time.

  Although the present invention has been described with the above embodiments, the technical scope of the present invention is not limited to the scope described in the embodiments, and various modifications or improvements can be added to these embodiments. . And embodiment which added such a change or improvement is also contained in the technical scope of the present invention. This is apparent from the claims and the means for solving the problems.
