  TECHNICAL FIELD The present invention relates to a network terminal failure handling system, a terminal device, a server device, a network terminal failure handling method, and a program, for example, a network terminal failure handling system suitable for application to a network terminal such as a mobile phone, a terminal device, and a server device. The present invention relates to a network terminal failure handling method and program.

  In recent years, network terminals such as mobile phones have been widely used. In particular, mobile phones are carried by many people regardless of gender. Although such network terminals that have passed the operation test are shipped normally, abnormalities (hereinafter referred to as failures) may occur during use.

  Failures can be broadly classified into those caused by hardware (hereinafter referred to as hardware failure) and those caused by software (hereinafter referred to as software failure). The former hardware failure must be repaired by replacing or bringing in the device, but the latter software failure can be dealt with by replacing the corresponding control program (also referred to as rewriting or upgrading). It is possible to repair.

  That is, the user checks the presence or absence of a corresponding control program (a program in which the cause of failure is corrected; hereinafter referred to as a correction program) via the network, and if a correction program exists, downloads it and rewrites the failure program. What is necessary is just to perform operation. Since there is no need to bring it to the service center, it does not take time.

As described above, a procedure for dealing with a failure of a network terminal such as a mobile phone has been established. However, this procedure requires a certain amount of knowledge and cannot be easily performed by anyone. This is because it is difficult to determine whether a hardware failure or a software failure, and it is not easy to find a modification program from the network and rewrite it.
Accordingly, there is a need for a network terminal failure handling system, a terminal device, a server device, a network terminal failure handling method, and a program that anyone can easily cope with when a network terminal such as a cellular phone fails.

For example, Patent Document 1 describes an invention that can be applied to a hardware failure of a terminal. In this invention, when failure information on a terminal is transmitted to a processing device on a network, A mechanism is disclosed in which an appropriate replacement part is selected by collation, and then the replacement part is sent to the user of the terminal.
Alternatively, Patent Document 2 describes an invention that can be applied to a software failure of a terminal. In this invention, when a version of a communication program being used in a terminal is notified to a server, the server communicates with that version. A mechanism is disclosed in which mode information is transmitted to a terminal, and the terminal communicates in the communication mode.
Alternatively, Patent Document 3 discloses a mechanism in which when a terminal fails, information indicating the content of the failure is displayed on a screen as a two-dimensional code, the two-dimensional code is photographed with a camera, and transmitted to a support center. Yes.
Alternatively, Patent Document 4 discloses a mechanism for taking a diagnostic program from a server into a terminal and transmitting a diagnostic result of the diagnostic program to the server.

JP 2003-233687 A JP 2006-344135 A JP 2008-028452 A JP 2009-017049 A

However, those described in Patent Documents 1 to 4 have the following problems.
<Patent Document 1>
Applicable only to terminal hardware failure.
<Patent Document 2>
The communication mode information corresponding to the version of the communication program being used on the terminal is merely taken from the server.
<Patent Document 3>
The failure information of the terminal is displayed on the screen as a two-dimensional code, and the two-dimensional code is photographed with a camera and transmitted to the support center.
<Patent Document 4>
It is just a matter of collecting terminal diagnostic results on a server.
Accordingly, any of the cited documents cannot flexibly cope with various failures of the network terminal and cannot be used easily by anyone.

It is a conceptual diagram of the program reading in the program reading part. It is a conceptual diagram of failure information detection. It is a figure which shows the flow of the system operation | movement of embodiment. It is a figure which shows the modification of embodiment. FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings taking application to a mobile phone as an example.
FIG. 1 is a schematic system configuration diagram of an embodiment. In this figure, a cellular phone 1 is a network terminal (or simply a terminal device) that can be connected to a network 3 such as a cellular phone network via the nearest base station 2 at all times or periodically or whenever necessary. .

  The mobile phone 1 has various functions as a network terminal, for example, a call that can make a voice call with another mobile phone or a general subscriber phone via a switching device (not shown) on the network 3. Functions, and an Internet function capable of accessing various server devices on the network 3 and receiving various services such as transmission / reception of e-mails and browsing of Internet contents such as homepages. In addition to these functions, for example, various functions such as a photographing function such as a still image and a moving image and a position positioning function using a GPS satellite may be provided.

  The mobile phone 1 realizes these functions by organic combination of software and hardware. That is, the cellular phone 1 holds a CPU (abbreviation of central processing unit, which is also a microcomputer or simply a computer) 4 that is a control element of a program control system, and software resources such as a control program executed by the CPU 4. Operation including a PROM (programmable read only memory) 5 that performs, a RAM (random access memory) 6 that provides an execution storage space (also referred to as a work area) for the control program to the CPU 4, a physical button such as a numeric keypad, and a touch panel A communication unit 9 that performs two-way wireless communication with the nearest base station 2 via the antenna 9a, a display unit 8 that includes a liquid crystal display, and the like; And a failure detection unit 10 that collects failure information.

  Here, software (or software resource) refers to electronic data such as a control program (also referred to as an operating system or application program) executed by the CPU 4, and “etc.” is necessary for the execution of the control program. Means various data. On the other hand, hardware (or hardware resource) generally refers to a physical component other than software. The CPU 4, PROM 5, RAM 6, operation unit 7, display unit 8, and communication unit 9 in the illustrated configuration. The failure detection unit 10 and the like correspond to that (hardware). However, the illustrated configuration representatively shows only main hardware of the mobile phone 1 in order to avoid congestion of the drawing. As hardware (not shown) of the mobile phone 1, for example, a camera unit responsible for a photographing function such as a still image or a moving image, a GPS receiving unit responsible for a position positioning function using a GPS satellite, or the like can be considered.

  The mobile phone 1 having such a configuration is used as a voice call terminal, used as a mail terminal, or used as an Internet terminal for browsing a homepage, and further, if necessary, a camera Although it is used as a GPS terminal or as a GPS terminal, some abnormal operation (hereinafter simply referred to as a failure) may occur during use in such various applications.

There are various types of failures, but they can be broadly divided into hardware failures and software failures. Since a hardware failure generally requires replacement or repair of the corresponding hardware element, it is often difficult to recover at the user stage, and it is necessary to bring it to the nearest service station.
On the other hand, software failures are often recovered by rewriting the program, and a correction program (hereinafter referred to as a “correction program”) that has been improved so as not to cause an error is downloaded from the network 3, and the fault occurs with the correction program. It is possible to recover from a failure by replacing (rewriting) the original program. For this reason, there is an advantage that recovery at the user stage is possible and there is no need to bring it into the service station.

  The illustrated server apparatus 11 provides a network terminal failure response service. In order to realize this service, the server device 11 has a first service function of distributing a correction program. When a software failure occurs in the mobile phone 1, the corresponding correction program may be downloaded from the server device 11 to the mobile phone 1 and the control program in the PROM 5 may be rewritten. However, since the correction program is generally created after a failure occurs, the correction program does not exist unless a certain amount of failure information has been accumulated. For this reason, an allowance is required until a correction program is created.

  Considering this point, the illustrated server apparatus 11 also has a second service function of distributing a diagnostic program. This diagnostic program is distributed to the mobile phone 1 in place of the correction program when the corresponding correction program is not found in the server device 11. By notifying the server device 11 of the diagnosis result, it is used as reference information for creating a subsequent correction program.

  The server device 11 has a configuration for realizing such two service functions (a distribution function of a correction program and a diagnostic program). "Server" (English: Server) refers to a system that provides some service in response to a request from a user (client) in the computer field. In general, servers vary from large to small systems depending on the scale of services. For example, large systems range from dedicated servers to distributed servers considering operational durability, and small systems include general-purpose computers such as personal computers as well as dedicated servers. The apparatus 11 may be any of these forms. In short, any device that can provide the two service functions (the distribution function of the correction program and the diagnostic program) to the client (mobile phone 1 in the figure) may be used.

  Although the configuration of the server device 11 is different for each of the above-described various forms (dedicated type, distributed type, or general-purpose type), the basics are arithmetic elements such as a CPU, storage elements such as a hard disk, communication unit, and keyboard. However, in order to avoid the congestion of the drawing, only the functions specific to the present embodiment are extracted and conceptually shown. It is illustrated as a simple block.

  That is, the server device 11 includes a communication unit 12 that transmits and receives data to and from the network 3, and a failure information analysis unit 13 that analyzes failure information of the mobile phone 1 that is appropriately captured through the communication unit 12. A program reading unit 14 that reads a required program (correction program or diagnostic program) from the storage unit 15 according to the analysis result of the failure information analysis unit 13 and transmits the program to the mobile phone 1 via the communication unit 12. Prepare. The server device 11 may naturally include an input device such as a keyboard and a mouse and a display device such as a liquid crystal display, following the configuration of a general computer system.

  FIG. 2 is a conceptual structural diagram of the storage space of the storage unit 15. In this figure, the storage unit 15 of the server device 11 is a large-capacity storage element composed of a hard disk or the like, and stores a correction program and a diagnostic program. The correction program is a modified version of the control program stored in the PROM 5 of the mobile phone 1, and the diagnosis program is a failure diagnosis program that is appropriately executed by the CPU 1 of the mobile phone 1. The illustrated storage unit 15 stores a plurality of correction programs A to D and a plurality of diagnosis programs a to d as an example.

  The failure information analysis unit 13 analyzes the failure information from the mobile phone 1, and the program reading unit 14 reads an appropriate correction program or diagnostic program from the storage unit 15 according to the analysis result, and carries it through the communication unit 12. Transmit to the telephone 1.

  FIG. 3 is a conceptual diagram of program reading in the program reading unit 14. In this drawing, failure categories K1 to K4 indicate failure categories analyzed by the failure information analysis unit 13, respectively. For example, K1 is a failure category during a process such as a call, K2 is a failure category during a process such as mail, K3 is a failure category during a process such as browsing a homepage, and K4 is a failure category during a process such as a camera. And so on. These failure categories are merely illustrative examples. Of course, other failure categories may be used.

  The program reading unit 14 first checks whether a correction program corresponding to the storage unit 15 is stored in accordance with the analysis result of the failure information analysis unit 13. If it is stored, the correction program is read out and transmitted to the mobile phone 1. On the other hand, if the corresponding correction program is not stored, a diagnostic program corresponding to the analysis result is stored in the storage unit 15. If it is stored, the diagnostic program is read out and transmitted to the mobile phone 1.

  Assume that the diagnostic program a is stored for the failure category K1 as shown in the figure (no correction program). Similarly, it is assumed that correction program A is stored for failure category K2 (no diagnostic program), correction program B is stored for failure category K3 (no diagnostic program), and for failure category K4, Assume that diagnostic program b is stored (no correction program).

  In such a case, if the analysis result of the failure information analysis unit 13 is K1, the program reading unit 14 transmits the diagnostic program a to the mobile phone 1, and the analysis result of the failure information analysis unit 13 is K2. If there is, the correction program A is transmitted to the mobile phone 1, and if the analysis result of the failure information analysis unit 13 is K3, the correction program B is transmitted to the mobile phone 1, and the failure information analysis unit 13 If the analysis result is K4, the diagnostic program b is transmitted to the mobile phone 1.

Next, failure detection in the mobile phone 1 will be described.
As described above, the server device 11 reads out an appropriate correction program or diagnostic program from the storage unit 15 according to the “failure information” from the mobile phone 1 and transmits it to the mobile phone 1. Here, “failure information” refers to information indicating the content of the software failure of the mobile phone 1, and specifically refers to information detected by the failure detection unit 10. There are various ways of detecting this failure information. For example, the failure information may be as follows.

  FIG. 4 is a conceptual diagram of failure information detection. In this figure, the vertically long figure schematically shows a control program executed by the CPU 4 of the mobile phone 1. Hereinafter, if this vertically long figure is simply referred to as a control program 16, the control program 16 is subdivided into several processes (processing units). For example, in the illustrated example, the process is subdivided into four processes P1 to P4. P1 corresponds to K1 in FIG. 3, P2 corresponds to K2 in FIG. 3, P3 corresponds to K3 in FIG. Corresponds to K4 in FIG.

  Such segmentation for each process is a conventional method for efficiently developing and modifying a program. This is because existing software assets can be effectively used by subdividing, and only a corresponding process part needs to be replaced when a failure occurs.

  Now, since error countermeasures are indispensable in general program development, an error processing routine (hereinafter referred to as error processing unit 17) is part of a program (in the figure, controlled) in case an unexpected error occurs. At the end of the program 16, trapping units 18 to 21 for trapping errors that have occurred in the processes are provided in each of the processes P 1 to P 4. It is customary to call the error processing unit 17 from ~ 21.

  The role of the error processing unit 17 is to recover from an abnormal state of the CPU 4 (stopped state, high load state or occurrence of an expected error). The illustrated error processing unit 17 performs an operation of returning from an abnormal state by performing a system reset (an operation for returning the execution start position of the control program 16 to the initial position) in the same manner as a general error processing unit. The operation unique to this embodiment, that is, the process number (any one of P1 to P4) that has fallen into an abnormal state is grasped from the trap unit 18 to 21 of the caller, and if necessary, immediately before the occurrence of the abnormal state The operation contents (the contents of the RAM 6) are recorded, and the process number and the operation contents are transmitted to the server apparatus 11 as "failure information".

  Thus, the failure information may be detected by the error processing unit 17 of the control program 16. In this case, the error processing unit 17 of the control program 16 corresponds to the failure detection unit 10 of FIG. However, the method of detecting the failure information is not limited to this mode (by the error processing unit 17 of the control program 16). As shown in FIG. 1, a hardware independent failure detection unit 10 is provided, and the failure detection unit 10 monitors the operation of each unit constantly or periodically. The process number at the time of occurrence (any one of P1 to P4) is grasped, and if necessary, the work contents (contents of the RAM 6) immediately before the occurrence of the abnormal state are recorded. ”May be transmitted to the server device 11.

Next, the system operation of the embodiment will be described.
FIG. 5 is a diagram illustrating a flow of system operation according to the embodiment. In this figure, the left flow (steps S101 to S108) shows the operation of the mobile phone 1, and the right flow (steps S201 to S207) shows the operation of the server device 11. Some dotted lines with arrows drawn between both flows indicate the timing of data transmission / reception from one flow to the other flow.

  In this figure, the failure detector 10 of the mobile phone 1 detects the presence or absence of an abnormality (failure) of the mobile phone 1 at all times or regularly. While the mobile phone 1 is not detecting a failure (during normal operation), the mobile phone 1 is performing a normal operation (waiting for a call, etc.), and during that time, the server device 11 is in a state of waiting for receiving failure information from the mobile phone 1. is there.

  Now, if any abnormality occurs in the mobile phone 1, this abnormality is detected by the failure detection unit 10 (step S101), and the process number (any one of P1 to P4) at the time of the abnormality occurs, and if necessary, an abnormal state occurs. The previous work contents (contents of the RAM 6) are transmitted to the server apparatus 11 as "abnormal information". In response to the reception of the “failure information”, the server device 11 analyzes the failure information (step S201), and searches whether the correction program corresponding to the process number is stored in the storage unit 15 (step S202). . Then, the presence / absence of the correction program is determined (step S203), and when the correction program is found, the correction program is transmitted to the mobile phone 1 (step S204), and the failure information is stored as subsequent data in the storage unit 15 or the like. After storing and storing (step S205), the flow is terminated, and the mobile phone 1 returns to the state of waiting for receiving failure information from the mobile phone 1 again.

  When receiving the program from the server device 11, the mobile phone 1 determines the type of the program (correction program / diagnostic program) (step S102). If it is a correction program, the corresponding process portion of the control program stored in the PROM 5 is rewritten with the received correction program (step S103), and when the rewriting is completed (step S104), restart (also referred to as system reset) ( After performing step S105), the flow is terminated and the normal operation (waiting for a call, etc.) is resumed.

As described above, in the system of the embodiment, when an abnormality occurs in the mobile phone 1, failure information including the process number at the time of the abnormality is transmitted to the server device 11, and sent back from the server device 11 according to the failure information. The control program of the PROM 5 can be rewritten with a correction program.
Therefore, the control program including the error can be rewritten with the correction program, and the effect that the failure of the mobile phone 1 can be recovered is obtained, and such a series of operations (fault information transmission and correction program fetching and rewriting) is performed manually. A network terminal failure response system that can be used automatically by anyone, regardless of age, gender, or anyone can be realized.

  By the way, the correction program is not initially stored in the storage unit 15 of the server device 11. This is because a correction program cannot be created unless there is at least one defect report. In such a case, in the present embodiment, a required diagnostic program is transmitted from the server device 11 to the mobile phone 1 instead of the correction program.

  That is, if NO is determined in step S203 of the server device 11, first, an appropriate diagnostic program corresponding to the failure information is read from the storage unit 15 and transmitted to the mobile phone 1 (step S206). The diagnosis program is executed (step S106), and the diagnosis result is transmitted to the server device 11 (step S107). Next, the server device 11 determines a coping method according to the diagnosis result, transmits a coping method message to the mobile phone 1 (step S207), and displays the coping method on the display unit 8 of the mobile phone 1 ( At the same time, a display completion notification is transmitted to the server device 11, and the server device 11 stores and saves the failure information as subsequent material in the storage unit 15 or the like (step S 205), and then the flow ends.

  In this way, a required diagnostic program is executed on the mobile phone 1 until a correction program is created, and the user of the mobile phone 1 is exchanged, for example, to a service center based on the diagnosis result. In addition to not inconvenience the user, the server device 11 collects and accumulates the diagnosis results, so that a more appropriate correction program with reference to the accumulated information The advantage that it can be made is obtained.

  In the above embodiment, the network 3 is accessed via the communication unit 9, but the present invention is not limited to this mode. For example, the following may be used.

  FIG. 6 is a diagram illustrating a modification of the embodiment. The difference from FIG. 1 is that an external device interface (IF) 22 is added to the mobile phone 1. The external device IF 22 may be a device that can be connected to a nearby external device (a personal computer in the figure) 23 via a wired medium such as a LAN cable, or a wireless medium such as WiFi or Bluetooth. It may be possible to connect to a nearby external device 23 via In this case, the external device 23 needs to be connected to the network 3 directly via a high-speed transmission line such as an optical cable or indirectly via a router (not shown).

  According to such a configuration, the server device 11 on the network 3 can be accessed using a high-speed line such as an optical cable instead of a relatively low-speed mobile phone line via the communication unit 9. The advantage is that the program can be received promptly.

  Note that. In the above description, the cellular phone 1 is taken as an example of the network terminal, but is not limited to this. Any program-controlled network terminal may be used. For example, a smartphone, an electronic book terminal, a tablet-type, notebook-type or desktop-type personal computer, or a game machine may be used.

The features of the present invention will be described below.
