Next, the operation of the slow diagnosis apparatus 10 of the present embodiment will be described in detail with reference to the drawings. 2 is a flowchart showing a method of diagnosing a slowness of a mobile communication terminal according to a preferred embodiment of the present invention.

First, the mobile communication terminal 30, which is the target of the slow diagnosis because the operation of the portable communication terminal is slower than the normal speed, is electrically connected to the slow diagnosis device 10 using the connection cable (step S11).

The communication section 11 of the slow diagnosis apparatus 10 attempts to communicate with the communication section 31 of the portable communication terminal 30 and performs communication with the mobile communication terminal 30 When communication with the terminal 30 is made, the app information, the memory information, the CPU information, and the past usage history of all the apps installed in the portable communication terminal 30 are received from the portable communication terminal 30 (step S11 ). If necessary, the terminal unique number and USIM information of the portable communication terminal 30 may be read together.

Next, the process proceeds to step S12. In step S12, the CPU occupancy rate determining unit 13 determines, based on the control unit 16, whether or not the CPU occupancy rate determining unit 13 has received the app information and CPU information from the portable communication terminal 30 (Step S12), and judges whether there is an app occupying at least a predetermined ratio, for example, 10% or more of the CPUs installed in the portable communication terminal 30 (Step S13). The confirmation in step S12 confirms each of a plurality of apps installed in the mobile communication terminal 30 for each of the apps in turn.

As a result of the judgment in the step S13, if there is no app occupying the CPU at a predetermined rate or more (step S13 = NO), the CPU occupancy rate judgment unit 13 judges the mobile communication terminal 30 as normal (step S14) and ends.

As a result of the judgment in the step S13, if there is an app occupying a predetermined ratio or more of the CPU (step S13 = YES), the CPU occupation rate judging unit 13 judges that the app occupying the CPU at a predetermined rate or more is a bad app (step S15) And, if necessary, update or delete the app.

In parallel with the step S12, the control unit 16 controls the parsing unit 14 to parse the past use record of all the apps received from the mobile communication terminal 30 in step S11 (step S21), and in step S22 And extracts the list of the apps from the past use history of all the parsed apps and compares them with the black list registered in the black list database 50 in advance.

As described above, the black list database 50 stores, for example, the name of the app, the version of the app, and the model and model of the mobile communication terminal that caused the malfunction, And the comparison in step S22 is made by comparing the names of the apps registered in the black list of the black list database 50 among the apps installed in the mobile communication terminal 30, Or by confirming whether or not there is a model and a model of the portable communication terminal.

If it is determined in step S22 that there is no app registered in the black list of the black list database 50 among the apps installed in the mobile communication terminal 30 (step S23 = NO), then in step S24, Is judged as a normal app that has no slow-down phenomenon and ends.

If there is an app registered in the black list of the black list database 50 among the apps installed in the mobile communication terminal 30 (step S23 = YES), the application is registered in the black list in step S25 The app is judged to be a bad app and is terminated. If necessary, the app is updated or deleted.

2, the control unit 17 may control the display unit 18 to visually display the determination results of steps S14, S15, S24, and S25 on the display unit 18, It is the same as described above.

In this embodiment, since the cause of the slowness of the mobile communication terminal is diagnosed by the judgment of the degree of the CPU occupation rate of the specific app and the presence or absence of the app listed in the black list in advance, It is possible to more reliably diagnose the cause of the slowing phenomenon.

As described above, in the present embodiment, the processing of steps S12 to S15 and the processing of steps S21 to S25 are performed simultaneously in parallel, thereby reducing the time required for diagnosing the slowness of the mobile communication terminal.

Although the preferred embodiments of the present invention have been described above, it is needless to say that the present invention is not limited to the above-described embodiments, and various changes or modifications can be made within the scope of the present invention.

In the above embodiment, it is explained that the processing from step S12 to step S15 and the processing from step S21 to step S25 are performed simultaneously in parallel. However, if the parallel processing capability of the slow diagnosis apparatus 10 is insufficient, , The remaining routines may be processed later. That is, for example, the processing of each step of steps S11 to S15 may be executed first, and then the processing of each step of steps S21 to S25 may be performed. Conversely, the processing of each step of steps S21 to S25 The processing of each step of steps S11 to S15 may be executed later.
