Description

  The present invention relates to a communication terminal capable of shifting to a locked state and a communication method using the communication terminal.

Mobile devices such as mobile phones can be locked by remote control to prevent unauthorized use in the event of loss or theft and to prevent data from being seen. For example, Japanese Patent Laid-Open No. 2007-266983 (Patent Document 1) describes switching to a lock mode by remote control (see abstract).
JP 2007-266983 A

  However, if the mobile device is locked and processing restrictions such as outgoing restrictions are in place, even if there is a request such as an incoming e-mail process or a synchronization process of the scheduler, the processing for those requests is not restricted. If it was the subject, it could not be executed. Therefore, after releasing the lock state, the user has to manually start, for example, an e-mail application and perform an operation for incoming e-mail processing, or start an application for performing synchronization processing of the scheduler . Therefore, it is inconvenient for the user because the e-mail cannot be acquired quickly, the scheduler synchronization process cannot be performed quickly, and the scheduler contents remain inconsistent. It was.

  Therefore, an object of the present invention is to realize a communication terminal and a communication method that can quickly process a processing request generated in a locked state after unlocking.

In order to solve the above-described problem, a communication terminal according to the present invention is a communication terminal capable of performing scheduler synchronization processing with a scheduler management server, and receiving means for receiving control information and receiving by the receiving means. Processing means for executing processing according to the controlled information and a lock for shifting to a locked state in which at least one of processing caused by information transmission / reception and operation reception is prohibited based on a user operation or an instruction from an external network means, wherein the control information by the receiving means is received when in the locked state by the lock means, without executing the processing by said processing means, and storage means for storing the control information, the processing Means is stored in the storage means as the control information instructing a synchronization process of the scheduler. When the lock state is released by the locking means, for performing synchronization processing of the scheduler in accordance with the control information stored in said storage means.

The communication method of the present invention is a communication method of a communication terminal capable of performing a scheduler synchronization process with a scheduler management server, a reception step for receiving control information , and the control information received by the reception step. A processing step for performing processing according to the above, a lock step for shifting to a locked state for prohibiting at least one of processing due to transmission / reception of information and operation reception based on an instruction from a user operation or an external network, and When the control information is received by the receiving step when the lock step is locked, the storage step stores the control information without executing the processing by the processing step. Suppose that the control information indicates scheduler synchronous processing , When it is stored in the storing step, when the locked state by the locking step is released, and executes synchronous processing of the scheduler in accordance with the control information stored in said storing step.

According to the present invention, when control information is received in a locked state in which at least one of processing caused by information transmission / reception and operation reception is prohibited based on a user operation or an instruction from an external network. The control information is stored. As a result, the control information received when in the locked state can be held, and when the locked state is released, control using the control information can be performed to realize an easy-to-use device. it can. Normally, when a communication device receives control information, the communication device is configured to execute processing based on the control information, and is in a locked state and cannot execute processing based on the control information. Even in such a case, by storing the control information itself, for example, by using only the control information after unlocking, the processing based on the control information can be executed. Therefore, the process based on the control information can be executed without manually starting the process according to the control information, and a quick and reliable process can be realized.

  The communication terminal according to the present invention further includes a database for storing processing priorities based on the control information, and the processing means executes processing based on the control information according to the priorities stored in the database. It is preferable to do.

  According to the present invention, processing of control information with a high priority is executed earlier, and a user-friendly device can be realized.

  In the communication terminal according to the present invention, when one control information is received by the receiving unit, one control information is stored in the storage unit, and then the one control information is received again by the receiving unit. The storage means preferably does not store the one control information received again.

  According to the present invention, after one control information is received and one control information is stored, when one control information is received again, the one control information received again is not stored. Therefore, it is no longer necessary to store a plurality of the same control signals. For example, when the lock is released, it is possible to prevent the same process from being repeated many times when it is desired to execute the process. An apparatus can be realized.

  According to the present invention, control information received when in the locked state can be held, and when the locked state is released, control using the control information is enabled, and an easy-to-use device is realized. can do.

  Embodiments of the present invention will be described with reference to the accompanying drawings. Where possible, the same parts are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a block diagram illustrating functions of the communication terminal 100 according to the present embodiment. The communication terminal 100 is a mobile device such as a mobile phone, and can be connected to, for example, a server 200 that backs up schedule data. The communication terminal 100 transmits schedule data from the server 200, and Synchronization processing with the managed schedule data can be performed. Further, when the server 200 functions as a mail server, it is possible to receive an incoming email signal from the server.

  As illustrated in FIG. 1, the communication terminal 100 includes a communication unit 101, a state confirmation unit 102, a function execution unit 103, function units 104 a, 104 b, 104 c, a storage unit 105, a priority database (DB) 106, and an operation unit 108. It is comprised including.

  This communication terminal 100 is realized by the hardware shown in FIG. FIG. 2 is a hardware configuration diagram of the communication terminal 100. As shown in FIG. 2, the communication terminal 100 shown in FIG. 1 physically includes a CPU 11, a RAM 12 and a ROM 13 that are main storage devices, an input device 14 such as a keyboard and a mouse that are input devices, and an output such as a display. The computer 15 includes a device 15, a communication module 16 that is a data transmission / reception device such as a network card, an auxiliary storage device 17 such as a hard disk, and the like. Each function described in FIG. 1 has an input device 14, an output device 15, and a communication module 16 under the control of the CPU 11 by reading predetermined computer software on hardware such as the CPU 11 and the RAM 12 shown in FIG. 2. This is realized by reading and writing data in the RAM 12 and the auxiliary storage device 17. Hereinafter, each functional block will be described based on the functional blocks shown in FIG.

  The communication unit 101 receives various control signals and information from an external network. For example, the communication unit 101 receives a control signal for remote lock from a remote terminal, receives a control signal for receiving an e-mail, and a scheduler. When various control signals are received such as reception of a control signal for synchronization processing such as a scheduler with the management server 200 and telephone directory data, it outputs a message to that effect to the function execution unit 103. Further, when the communication unit 101 receives these various control signals, the communication unit 101 outputs a message to that effect to the state confirmation unit 102.

  When the communication unit 101 receives the control signal, the state confirmation unit 102 determines whether or not the state of the communication terminal 100 is the remote lock state. For example, the state confirmation unit 102 can confirm whether or not it is in the remote lock state based on a flag indicating that it is in the remote lock state. This flag is stored in the function execution unit 103. When the communication unit 101 receives a control signal for shifting to the remote lock state, the flag for that purpose is stored in the function execution unit 103. .

  Here, the remote lock state refers to a state in which the user cannot operate the communication terminal 100 or the communication terminal cannot perform processing due to transmission / reception of various signals. It means a state in which a user cannot make a call, or cannot browse even if an e-mail is received (or cannot receive the e-mail). In general, in the case of theft or loss, the communication terminal 100 cannot be abused by a third party.

  Further, when determining that it is in the remote lock state, the state confirmation unit 102 outputs the control signal received by the communication unit 101 to the storage unit 105 to be stored. When the state confirmation unit 102 determines that it is not in the remote lock state, the control signal received by the communication unit 101 is processed by the function execution unit 103.

  Further, when the communication unit 101 receives a plurality of the same control signals when in the remote lock state, the state confirmation unit 102 discards the control signals received later without being stored in the storage unit 105. Process. Accordingly, a plurality of overlapping control signals are not stored, the use efficiency of the memory can be improved, and the same process is not repeated many times when the process based on the control signal is performed.

  The function execution unit 103 is a part that executes the function units 104 a to 104 c according to the control signal received by the communication unit 101.

  Furthermore, when the remote lock is released based on a user operation or a remote operation from an external network, the function execution unit 103 has a priority according to the type of control signal stored in the priority DB 106 and the storage unit 105. Perform each function. Specifically, the function execution unit 103 determines whether a control signal is stored in the storage unit 105, and determines whether there are a plurality of control signals. When it is determined that more than one is stored, the function execution unit 103 checks the priority stored in the priority DB 106 and causes the function execution unit 103 to execute each function unit according to the priority. Give instructions.

  The functional units 104a to 104c are various functions of the communication terminal 100, such as an incoming e-mail processing function and a scheduler synchronous processing function.

  The storage unit 105 is a part that stores a control signal output when the state confirmation unit 102 determines that the remote lock state is established.

  The priority database (DB) 106 is a part that stores priorities that define in what priority order the control signals stored in the storage unit 105 are processed when the remote lock state is released. . Specifically, as shown in FIG. 3, functions and priorities are stored in association with each other. In the example of FIG. 3, the priority is defined and stored for the e-mail incoming function, and the control indicating the e-mail incoming function and the synchronization processing of the scheduler when the lock is released. When the signals are stored in the storage unit 105, the function execution unit 103 activates the e-mail incoming function first.

  The operation unit 108 is a part for the user to operate the communication terminal 100, and is, for example, an alphanumeric key. By performing this key operation, the user can make / receive a call, or can be locked (remote). The same state as the locked state).

  Processing of the communication terminal 100 configured as described above will be described. FIG. 4 is a flowchart showing processing according to the presence or absence of the remote lock state of the communication terminal 100 of the present embodiment.

  First, a control signal is received by the communication unit 101 (S101). For example, this control signal is an incoming email signal or a synchronization processing signal of a scheduler. When these signals are received, the state confirmation unit 102 determines whether or not the remote lock state is set (S102). If it is determined that the remote lock state is not set, the function execution unit 103 selects one of the function units 104a to 104c designated by the control signal and executes various functions (S103).

  In S102, if it is determined by the state confirmation unit 102 that the lock state is set, it is searched whether or not the same control signal is already stored in the storage unit 105 (S104). Then, when it is determined that the same control signal is stored (S105: Yes), the storage process for the storage unit 105 by the state confirmation unit 102 is not performed, and the received control signal is discarded (S106).

  Further, when the state confirmation unit 102 determines that the same control signal is not stored in the storage unit 105 (S105: No), the state confirmation unit 102 stores the received control signal in the storage unit 105. (S107).

  By such a process, when a control signal such as an incoming e-mail or a scheduler synchronization process is received during remote lock, the control signal is stored.

  Next, processing when the remote lock is released will be described. FIG. 5 is an explanatory diagram showing processing of the communication terminal 100 when the remote lock is released.

  First, the remote lock state is canceled by the function execution unit 103 in accordance with an operation by the user on the operation unit 108 or a remote operation based on a control signal received by the communication unit 101 (S201). Then, the function execution unit 103 determines whether or not a control signal is stored in the storage unit 105 (S202). Here, if it is determined that the control signal is not stored, no special process is performed, and the process shifts to a standby state as the process is completed (S207).

  When it is determined in S202 that the control signal is stored, the state check unit 102 determines whether or not a plurality (N) of control signals are stored (S203). If it is determined that a plurality (N) are stored, the stored number N is temporarily stored, and the function execution unit 103 checks the priority information stored in the priority DB 106. (S204). And according to the confirmed priority information, each function part 104a-104c is started by the function execution part 103 (S205). Here, the temporarily held N is decremented by 1 (S205).

  When the function execution unit 103 determines that a plurality of control signals are not stored (S203: No), the function unit 104 (any one of 104a to 104c) corresponding to the stored control signal is activated. (S205). Here, N is decremented by one.

  Then, whether or not N = 0 is determined by the function execution unit 103, and the function unit 104 corresponding to the control signal according to the priority is activated until N becomes 0 (S204). When N = 0, the process is completed (S207).

  As described above, when the remote lock is released, the function unit 104 is activated based on the control signal stored in the storage unit 105, so that even if the control signal is received in the remote lock state, the remote lock state is established. As soon as is released, processing based on the control signal can be executed.

  When another control signal is received by the communication unit 101 during the process of S205 described above, the other control signal is temporarily stored in the storage unit 105, and the control signal previously stored in the storage unit 105 is used. After various defined functions are executed, functions corresponding to the other control signals are executed. Not limited to this, the control signal received during the process of S205 and the control information already stored in the storage unit 105 should be combined and executed after the process of S205 based on the priority information of the priority DB 106. The control signal may be determined. Further, the present invention is not limited to the process of S205, and when a plurality of control signal reception processes are performed almost simultaneously, similarly, while processing one control signal, the other control signal is stored in the storage unit 105. May be stored.

  Next, operational effects of the communication terminal 100 of the present embodiment will be described. In this communication terminal 100, based on a user operation or an instruction from an external network, the function execution unit 103 makes a transition to a locked state in which processing caused by information transmission / reception is prohibited, and control information is received when in the locked state. Then, control information is stored in the storage unit 105. As a result, the control information received when in the locked state can be held, and when the locked state is released, control using the control information can be performed to realize an easy-to-use device. it can. Normally, when the communication terminal 100 receives control information, the communication terminal 100 is configured to execute processing based on the control information, and is in a locked state and cannot execute processing based on the control information. Even so, by storing the control information itself, as will be described later, it is possible to execute processing based on the control information by using only the control information after unlocking.

  For example, in the communication terminal 100, when the lock state is released by a user operation by the operation unit 108 or a remote operation, the function execution unit 103 reads the control information received during the lock state and stored in the storage unit 105, By activating the corresponding function unit 104, processing according to the control information can be executed. Therefore, it is possible to perform processing without manually starting processing according to the control information, and it is possible to realize quick and reliable processing. For example, in the communication terminal 100 that can perform processing for obtaining a mail from a server based on an incoming signal when receiving an incoming signal of a mail, the incoming signal itself is stored when the terminal is in a locked state, and after unlocking If it is configured to refer to the stored incoming signal, an operation for promptly obtaining mail can be performed. Similarly, for the synchronization processing of the scheduler and the phone book data, if the synchronization signal is received while in the locked state, the synchronization signal itself is stored, so that only the synchronization signal can be referred to after unlocking. The synchronization process can be executed automatically and quickly. Therefore, it is not necessary for the user to start the application and perform each acquisition process and synchronization process.

  Further, in the communication terminal 100 of the present embodiment, the function execution unit 103 activates the function unit 104 corresponding to the control information according to the priority defined in advance in the priority DB 106, and the function unit 104 executes the process. Can do. Therefore, the control information processing with high priority is executed earlier, and a user-friendly device can be realized.

  Further, in the communication terminal 100 according to the present embodiment, control information is received by the communication unit 101, and after the control information is stored in the storage unit 105, the same control information as the control information already stored is received again by the communication unit 101. Then, the state confirmation unit 102 discards the control information so that the control information received again is not stored in the storage unit 105. Therefore, it is not necessary to store a plurality of the same control signals. For example, when the processing is to be executed when the lock is released, it is possible to prevent the same processing from being performed many times, and a user-friendly device can be obtained. Can be realized.
