The normal operation notification information is information indicating that the BTS 4 is operating normally. The wireless device 6 can confirm that the BTS 4 is operating normally by receiving normal operation notification information periodically transmitted from the BTS 4.

  The failure information writing unit 48 writes failure information related to a failure that has occurred in the own device in the failure information storage unit 45 of the storage unit 43.

  The execution unit 49 executes processing for removing a failure in accordance with an instruction received from the wireless device 6 via the communication path 20.

  The CPU 64 includes a position information acquisition unit 66, a determination unit 67, a failure information acquisition unit 68, a transmission unit 69, a reception unit 70, and an instruction unit 71. The CPU 64 controls the functions of the determination unit 67, the position information acquisition unit 66, the failure information acquisition unit 68, the transmission unit 69, the reception unit 70, and the instruction unit 71 by executing and controlling various programs stored in the storage unit 63. This is implemented to control the respective units of the wireless device 6 in an integrated manner and execute the following processes.

  The position information acquisition unit 66 acquires position information (latitude and longitude) of the own device. For example, the position information acquisition unit 66 has a GPS (Global Positioning System) function and acquires position information of the wireless device 6 transmitted from a GPS satellite.

  The determination unit 67 does not regularly receive the normal operation notification information transmitted from the BTS 4 via the communication path 10 and the BTS 4 has a failure when it is within the communication range of the BTS 4. It is determined that it has occurred. More specifically, the determination unit 67 determines whether or not the mobile terminal is within the communication area of the BTS 4 based on the position information of the own device acquired by the position information acquisition unit 66.

  When the determination unit 67 determines that a failure has occurred in the BTS 4, the failure information acquisition unit 68 acquires failure information related to the failure from the storage unit 43 of the BTS 4 via the communication path 20. More specifically, the storage unit 63 stores a program for executing a procedure for reading out the failure information stored in the failure information storage unit 45, and the failure information acquisition unit 68 executes this program. Thus, the failure information is read out via the communication path 20. The failure information acquisition unit 68 stores the read failure information in the storage unit 63.

  The transmission unit 69 transmits the failure information acquired by the failure information acquisition unit 68 to the BTS 5 via the communication path 10.

  The receiving unit 70 receives failure countermeasure information corresponding to the failure information from the BTS 5.

  The instruction unit 71 instructs the execution of processing for removing a failure that has occurred in the BTS 4 according to the failure countermeasure information received by the receiving unit 70.

  A method for generating the failure countermeasure information will be described in more detail. The transmission unit 69 searches for a BTS 5 that can be connected via the communication path 10 in addition to the BTS 4, and transmits failure information to the searched BTS 5 via the communication path 10. The BTS 5 transmits the failure information to the maintenance monitoring station 2 as a higher-level device via the network circuit 3. The maintenance monitoring station 2 decodes the received failure information, and generates failure countermeasure information including update information such as a software program according to the content of the failure from the obtained decoding result. The maintenance monitoring station 2 transmits failure countermeasure information generated via the network circuit 3 to the BTS 5. The BTS 5 transmits failure countermeasure information to the wireless device 6 via the communication path 10.

  The instruction unit 71 stores the received failure countermeasure information in the storage unit 63, decodes the failure countermeasure information, and specifies the content of the failure from the obtained decoding result.

  The instruction unit 71 determines a process for removing the failure according to the content of the specified failure. For example, when the failure countermeasure information includes software program and parameter update information, the instruction unit 71 transmits the software program and parameter update information and update instruction to the BTS 4 via the communication path 20. The instruction unit 71 instructs the BTS 5 to restart via the communication path 20 when the failure countermeasure information includes a restart instruction.

  Updating the software program and parameters of the BTS 4 is effective for failures caused by a software program failure, a data failure stored in the storage unit 43, a parameter setting failure, or the like. When the failure countermeasure information includes update information, the instruction unit 71 stores the update information in the update information storage unit 46 via the communication path 20 and instructs to update the software program and parameters.

  The restart of BTS4 is caused by a temporary or transient hardware failure such as a hang-up of the control unit 44 of the BTS4 due to a software program bug or exception processing, an instantaneous interruption of the power supply voltage, or a loss of synchronization of the clock synchronization circuit. This is effective for failures caused by 44 stop states. The instruction unit 71 instructs the BTS 4 to restart via the communication path 20 when the failure countermeasure information indicates that the BTS 4 is in a stopped state and includes a restart instruction. In the restart instruction, for example, a restart signal line (not shown) may be provided from the interface unit 42 to the control unit 44, and a program for enabling the restart signal line may be executed from the interface unit 42.

  The display unit 65 displays various information necessary for the user to use the function of the wireless device 6. For example, the various types of information include power status, radio wave intensity, and site data on the Internet. The display unit 65 displays the contact information of the maintenance department of the mobile communication system 100 in accordance with the instruction from the CPU 64.

  Next, a maintenance process flow in the mobile communication system 100 will be described with reference to FIG.

  The BTS 4 transmits normal operation notification information to the wireless device 6 periodically (every predetermined time) via the communication path 10. CPU64 (determination part 67) of the radio | wireless apparatus 6 waits until predetermined time passes after receiving normal operation notification information (step S1; No). When the normal operation notification information is not received and a predetermined time has elapsed (step S1; Yes), the CPU 64 (determination unit 67) communicates with the BTS 4 based on the position information acquired by the position information acquisition unit 66. It is determined whether or not the user is in the area (step S2). If the own device is not within the communication area of the BTS 4 (step S2; No), it is considered that normal operation notification information cannot be received via the communication path 10, and the CPU 64 returns to step S1.

  When the own device is within the communication area of BTS 4 (step S2; Yes), it is considered that a failure has occurred in BTS 4, and therefore CPU 64 (failure information acquisition unit 68) is stored in storage unit 43 via communication path 20. Fault information is read (step S3). Subsequently, the CPU 64 (transmission unit 69) transmits failure information to the BTS 5 via the communication path 10 (step S4). Next, the CPU 64 (reception unit 70) receives failure countermeasure information from the BTS 5 via the communication path 10 (step S5). Further, the CPU 64 (instruction unit 71) specifies the content of the failure based on the received failure countermeasure information (step S6).

  Subsequently, the CPU 64 (instruction unit 71) determines whether or not the software program and parameters need to be updated based on the content of the specified failure (step S7). When updating is necessary (step S7; Yes), the CPU 64 (instruction unit 71) instructs the BTS 4 to update the software program and parameters via the communication path 20 (step S8). More specifically, the CPU 64 (instruction unit 71) stores the update information in the update information storage unit 46 of the BTS 4 via the communication path 20. Subsequently, the CPU 64 (instruction unit 71) instructs the control unit 44 of the BTS 4 to update the software program and parameters using the update information. In response to this, the control unit 44 of the BTS 4 updates the software program and parameters.

  On the other hand, when it is not necessary to update the software program and parameters (step S7; No), the control unit 64 (instruction unit 71) determines whether it is necessary to restart the BTS 4 based on the content of the failure ( Step S9). When it is necessary to restart the BTS 4 (step S9; Yes), the control unit 64 (instruction unit 71) instructs the control unit 44 of the BTS 4 to restart through the communication path 20 (step S10). In response to this, the BTS 4 executes a restart.

  When the failure is removed by updating the software program and parameters or restarting the BTS 4 (step S11; Yes), the CPU 64 returns to step S1. If the fault is not removed by updating the software program and parameters, or restarting the BTS 4 (step S11; No), or if it is not necessary to restart the BTS 4 (step S9; No), removing the fault in this process Therefore, the CPU 64 displays the contact information of the maintenance department on the display unit 65 (step S12).

  As described above in detail, according to the above-described embodiment, the BTS 4 periodically transmits normal operation notification information to the wireless device 6 via the communication path 10. As a result, when the wireless device 6 cannot receive the normal operation notification information, it can be determined that a failure has occurred in the BTS 4. The BTS 4 can read out the failure information from the outside via the communication path 20 and can execute a process for removing the failure according to the instruction received via the communication path 20. As a result, the failure that has occurred in the BTS 4 can be quickly removed.

  In the above embodiment, the software program and the parameters are updated based on the content of the failure. As a result, it is possible to eliminate a failure caused by a software program failure, a data failure stored in the storage unit 43, a parameter setting failure, or the like.

  In the above embodiment, the BTS 4 is restarted based on the content of the failure. By doing so, the control unit 44 due to a temporary or transient hardware failure such as a hang-up of the control unit 44 of the BTS 4 due to a malfunction of the software program or an exception process, an instantaneous interruption of the power supply voltage, a loss of synchronization of the clock synchronization circuit, or the like. It is possible to eliminate the trouble caused by the stop state. In general, the restart switch of the BTS 4 is protected by a cover or a casing so as not to touch it accidentally. Since the instruction unit 71 restarts the BTS 4 based on the failure countermeasure information, it is not necessary to remove and attach the cover and the housing. As a result, the burden on the operator is reduced and the failure is more easily removed. be able to.

  Further, in the above embodiment, the communication path 20 is short-range wireless communication not involving a relay station. This eliminates the need for a dedicated debugging communication tool, thereby reducing the burden on the operator and removing the failure more easily.

  Further, the wireless device 6 includes a position information acquisition unit 66, and the determination unit 67 is based on the position information acquired by the position information acquisition unit 66 when the normal operation notification information is not received from the transmission unit 47 every predetermined time. Then, it is determined whether or not the position of the own device is within the communication range of the BTS 4. By doing this, the wireless device 6 can recognize that the normal operation notification information could not be received because it was out of the communication area of the BTS 4, not because a failure occurred in the BTS 4. Can be prevented.

  The BTS 4 may be a low-power type femtocell BTS installed in a narrow area such as a home or office where radio waves are difficult to reach, or in the basement, or a normal BTS installed outdoors. There may be. The same applies to BTS5.

  If communication connection via the communication path 20 is not possible in the failure information read (step S3), the update instruction including the update information write (step S8), and the BTS4 restart instruction (step S10), a plurality of times A communication connection may be attempted. In this case, if the communication connection cannot be established after trying the communication connection a predetermined number of times or more, the CPU 64 may display the contact information of the maintenance department on the display unit 65 (step S12).

  In addition, when communication connection via the communication path 10 is not possible in transmission of failure information (step S4) and reception of failure countermeasure information (step S5), communication connection may be attempted a plurality of times. In this case, if the communication connection cannot be established after trying the communication connection a predetermined number of times or more, the CPU 64 may display the contact information of the maintenance department on the display unit 65 (step S12).

  Further, when the failure content cannot be specified in the specification of the failure content (step S6), the CPU 64 may display the contact information of the maintenance department on the display unit 65 (step S12). .

  The display unit 65 may display a list of maintenance work items specified based on the content of the failure and guidance on how to deal with the failure that will be required in the future. In this case, a mail for providing information distributed from the upper station 1 and the maintenance monitoring station 2 may be displayed. Further, in addition to the display, the wireless device 6 may execute notification by outputting a notification sound from a speaker (not shown) or vibration of a vibrator (not shown).

  In the above embodiment, the program to be executed is a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disc Read-Only Memory), a DVD (Digital Versatile Disc), or an MO (Magneto-Optical disc). It is also possible to configure a system that executes the above-described processing by storing and distributing the program and installing the program.

  Further, the program may be stored in a disk device or the like included in a predetermined server device on a communication network such as the Internet, and may be downloaded, for example, superimposed on a carrier wave.

  In addition, when the above functions are realized by sharing an OS (Operating System), or when the functions are realized by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed. You may also download it.

  Various embodiments and modifications can be made to the present invention without departing from the broad spirit and scope of the present invention.
