In order to solve the above problems, the present invention proposes a processing method for a faulty frequency band, which determines whether the frequency band is a faulty frequency band by using the transmission power of the frequency band and the power of the feedback signal obtained by sending a signal based on the transmission power of the frequency band, so that it can be effectively Realize the detection of the faulty frequency band, and when the frequency band is determined to be the faulty frequency band, shield the frequency band so that the mobile terminal will not use the faulty frequency band, effectively avoiding the impact of using the faulty frequency band on the network search speed and cell switching, and avoiding The problem of waste of power of mobile terminals caused by using faulty frequency bands.

Please refer to FIG. 2 , which is a schematic flow chart of a processing method for faulty frequency bands in the first embodiment of the present invention. The processing method for faulty frequency bands includes:

Step 201, when a faulty frequency band detection instruction is detected, determine the transmission power of each frequency band to be detected;

In the embodiment of the present invention, the method for processing the faulty frequency band is executed by a processing device for the faulty frequency band (hereinafter simply referred to as: processing device), and the processing device is a part of the mobile terminal shown in FIG. 1 .

In the embodiment of the present invention, the mobile terminal will detect the faulty frequency band every preset time period, and can also perform a faulty frequency band detection in a fixed state. For example, the mobile terminal can generate a faulty frequency band immediately after each startup. The frequency band detection command enables the processing device to process the faulty frequency band after detecting the faulty frequency band detection command. Alternatively, after the mobile terminal is started, it generates a faulty frequency band detection command every N (eg, 5) hours, so that the processing device can process the faulty frequency band after detecting the faulty frequency band detection command. Therefore, it can be understood that in practical applications, the timing of generating the faulty frequency band detection instruction may be preset to start the processing device to process the faulty frequency band, which is not limited here. Wherein, the processing of the faulty frequency band by the processing device includes detecting the faulty frequency band and shielding the faulty frequency band, which will be described in detail below.

In the embodiment of the present invention, the failure of the frequency band is mainly due to the failure of the physical link corresponding to the frequency band. The physical link usually includes devices such as duplexers, filters, and power amplifiers. Any device in the physical link Any damage will cause the physical link to fail to work normally, which means that the frequency band corresponding to the physical link cannot be used, and this frequency band is the faulty frequency band.

In the embodiment of the present invention, when the processing device detects the faulty frequency band detection instruction, it will determine the transmission power of each frequency band to be detected.

Wherein, the frequency band to be detected refers to the frequency band that the mobile terminal can use. Specifically, when the mobile terminal is started, it will load all the frequency bands preset in the saved non-volatile data (NV data), and only when the mobile terminal is loaded After the frequency band in NV, the frequency band can be used. Therefore, the processing device may determine all frequency bands to be detected by determining all loaded frequency bands. Since different frequency bands correspond to different transmission powers, and the mapping relationship between frequency bands and transmission powers is preset in the mobile terminal, the processing device may, after determining the frequency bands to be detected, base on the above-mentioned frequency bands and transmission power The relationship between factors determines the transmission power of each frequency band to be detected.

Step 202, for each of the frequency bands, according to the transmission power of the frequency band and the power of the feedback signal obtained by sending signals based on the transmission power of the frequency band, determine whether the frequency band is a faulty frequency band, and after determining When the frequency band is a fault frequency band, shield the frequency band.

In the embodiment of the present invention, for each frequency band to be detected, the processing device will detect each of the frequency bands to determine whether it is a faulty frequency band, and when a certain frequency band is a faulty frequency band, shield the frequency band.

Specifically, for each of the frequency bands to be detected, the processing device will determine whether the frequency band is a fault frequency band according to the transmission power of the frequency band and the power of the feedback signal obtained by sending signals based on the transmission power of the frequency band, and When the frequency band is determined to be a faulty frequency band, block the frequency band. For example, taking frequency band A as an example, if the transmission power of frequency band A is 23dBm, the processing device will use the physical link of frequency band A to transmit signals according to the transmission power of 23dBm, and obtain the signal obtained by transmitting signals according to the transmission power of 23dBm A feedback signal, and calculating the power of the feedback signal. After obtaining the power of the feedback signal, use the transmission power 23dBm of the frequency band A and the power of the feedback signal to determine whether the frequency band A is a fault frequency band, and when the frequency band A is determined to be a fault frequency band, shield the frequency band.

In the embodiment of the present invention, when a faulty frequency band detection instruction is detected, the transmit power of each frequency band to be detected is determined, and for each frequency band in each frequency band, a signal is sent according to the transmit power of the frequency band and based on the transmit power of the frequency band The power of the obtained feedback signal is used to determine whether the frequency band is a fault frequency band, and when it is determined that the frequency band is a fault frequency band, the frequency band is shielded. By detecting the faulty frequency band and shielding the faulty frequency band, the mobile terminal will not use the faulty frequency band, effectively avoiding the impact of using the faulty frequency band on the speed of network search and cell switching, and avoiding the problem of power waste caused by using the faulty frequency band .

Please refer to FIG. 3 , which is a schematic flow chart of a method for processing faulty frequency bands in the second embodiment of the present invention. The processing method for faulty frequency bands includes:

Step 301, when a faulty frequency band detection instruction is detected, determine the transmission power of each frequency band to be detected;

It should be noted that step 301 is similar to the content described in step 201 in the first embodiment shown in FIG. 2 , and details are not repeated here.

Step 302, for each of the frequency bands, send a signal according to the transmission power of the frequency band, and determine the power of the feedback signal of the signal feedback sent by the coupling link in the mobile terminal based on the transmission power of the frequency band;

Step 303. Determine whether the frequency band is a fault frequency band according to the transmission power of the frequency band and the power of the feedback signal;

Step 304, if it is determined that the frequency band is a faulty frequency band, shield the frequency band.

In the embodiment of the present invention, for each of the frequency bands to be detected, the processing device will determine whether the frequency band is a faulty frequency band according to the content described in steps 302 to 304 until all frequency bands are detected.

In the embodiment of the present invention, taking a frequency band as an example, when the processing device detects whether the frequency band is a faulty frequency band, it will send a signal according to the transmission power of the frequency band, for example, if the transmission power of the frequency band is 23dBm, then the processing The device will first determine the physical link corresponding to the frequency band, and send signals through the physical link according to the transmission power of 23dBm.

Wherein, after the processing device sends the signal according to the transmission power of the frequency band, the signal will reach the coupling link in the mobile terminal, and the coupling link sends the feedback signal to the processing device, so that the processing device can determine to transmit the signal according to the transmission power of the frequency band. The resulting feedback signal and the power of that feedback signal. It should be noted that, in the mobile terminal, the relationship between the processing device, the physical link of the frequency band, and the coupling link is: the physical links of all the frequency bands in the mobile terminal are connected to the coupling link, and the processing device can control the physical link of the frequency band. The channel sends a signal according to the specified transmission power, and the signal will pass through the coupling link connected to the physical link, and the coupling link will feed back the passing signal to the processing device, so that the processing device can determine the power of the fed back signal.

In the embodiment of the present invention, the processing device will also determine whether the frequency band is a faulty frequency band according to the transmission power of the frequency band and the power of the feedback signal, and shield the frequency band if it is determined that the frequency band is a faulty frequency band.

In the embodiment of the present invention, when a faulty frequency band detection command is detected, the transmission power of each frequency band to be detected is determined, and for each frequency band in each frequency band, a signal is sent according to the transmission power of the frequency band, and the coupling chain in the mobile terminal is determined. According to the power of the feedback signal sent by the transmission power of the frequency band, determine whether the frequency band is a fault frequency band according to the transmission power of the frequency band and the power of the feedback signal. If it is determined that the frequency band is a fault frequency band, then shield the frequency band. By detecting the faulty frequency band and shielding the faulty frequency band, the mobile terminal will not use the faulty frequency band, effectively avoiding the impact of using the faulty frequency band on the speed of network search and cell switching, and avoiding the problem of power waste caused by using the faulty frequency band .

Please refer to FIG. 4 , which is a schematic flow chart of the refinement steps of step 303 in the second embodiment shown in FIG. 3 of the present invention. The refinement steps of step 303 include:

Step 401. Find the correspondence between the preset transmission power and the coupling power of the coupling link, and determine the coupling power corresponding to the transmission power of the frequency band;

Step 402. Determine whether the frequency band is a faulty frequency band according to the coupling power and the power of the feedback signal.

In the embodiment of the present invention, the corresponding relationship between the transmission power of each frequency band and the coupling power of the coupling link is preset in the mobile terminal, where the coupling power of the coupling link refers to the coupling The power of the feedback signal for link feedback.

In the embodiment of the present invention, after the processing device determines the power of the feedback signal fed back by the coupling link, it will search for the correspondence between the preset transmission power and the coupling power of the coupling link, and determine the corresponding relationship between the transmission power of the frequency band. coupling power, and determine whether the frequency band is a fault frequency band according to the coupling power and the power of the feedback signal.

Wherein, determining whether the frequency band is a fault frequency band according to the coupling power and the power of the feedback signal specifically includes: calculating the difference between the coupling power and the power of the feedback signal; if the difference is within a preset range, then determining that the frequency band is not Faulty frequency band; if the difference is not within the preset range, it is determined that this frequency band is a faulty frequency band.

It should be noted that, in the embodiment of the present invention, when a frequency band fails, the corresponding physical link has two situations, one is that the signal cannot be sent at all, and the other is that the signal can be sent, but the power of the sent signal is far It is much smaller than the power of the signal that actually needs to be sent. Therefore, when the processing device obtains the feedback signal obtained by sending the signal based on the transmission power of the frequency band, it specifically includes: if the processing device does not receive the feedback signal fed back by the coupling link within the preset time period , it is determined that the power of the feedback signal fed back by the coupling link is zero, and if the processing device receives the feedback signal fed back by the coupling link within a preset time period, calculates the power of the feedback signal.

In the embodiment of the present invention, the coupling power corresponding to the transmission power of the frequency band can be effectively determined by searching the correspondence between the preset transmission power and the coupling power of the coupling link, and according to the coupling power and the feedback signal The power can effectively determine whether the frequency band is a fault frequency band, so as to realize the detection of the fault frequency band.

Please refer to FIG. 5, which is a schematic flow chart of the refinement steps of step 304 in the second embodiment shown in FIG. 3 of the present invention, and the refinement steps of step 304 include:

Step 501, if it is determined that the frequency band is a faulty frequency band, search for the frequency band data of each frequency band preset in the non-volatile data stored in the mobile terminal, and determine the frequency band data of the faulty frequency band;

Step 205, delete the determined frequency band data of the faulty frequency band, and restart the mobile terminal.

In the embodiment of the present invention, the non-volatile data (NV data) has been saved in the mobile terminal, and the non-volatile data usually includes the configuration data of the mobile terminal, and after the mobile terminal restarts, the non-volatile data also Will not change or be deleted, for example, the time of the set alarm clock will be saved in non-volatile data.

Among them, the non-volatile data will also save the frequency band data of all the frequency bands that the mobile terminal can use, and the frequency band data includes the transmission power corresponding to the frequency band, the physical link corresponding to the frequency band, the range of the frequency band and so on.

Wherein, the mobile terminal will load non-volatile data every time it starts up, so as to complete the initialization of the mobile terminal.

In the embodiment of the present invention, when the processing device determines that the frequency band is a faulty frequency band, it will search for the frequency band data of each frequency band preset in the non-volatile data stored in the mobile terminal, determine the frequency band data of the faulty frequency band, and delete Frequency band data of the faulty frequency band, and restart the mobile terminal.

Wherein, restarting the mobile terminal mainly considers that: when the mobile terminal is started, it needs to load the frequency band data of each frequency band in the non-volatile data, so as to use each frequency band for communication. When the mobile terminal is in the activated state, if the processing device detects the faulty frequency band and deletes the faulty frequency band, the mobile terminal will still use the faulty frequency band when using the frequency band for communication, and must restart the mobile terminal and restart Only by loading the frequency band data of the frequency band from which the faulty frequency band has been deleted can the shielding of the faulty frequency band be truly realized.

It should be noted that, in the embodiment of the present invention, before the mobile terminal is restarted, a prompt message can be sent to remind the user that the mobile terminal needs to be restarted to make the communication of the mobile terminal normal, and if a restart confirmation instruction is detected, the mobile terminal will be restarted. , if the restart cancellation instruction is detected, cancel the restart of the mobile terminal so as to meet the user's requirements.

Wherein, after restarting the mobile terminal, the mobile terminal will load the frequency band data of the frequency band from which the faulty frequency band has been deleted, so that the mobile terminal will no longer use the faulty frequency band during use, so as to complete the shielding of the faulty frequency band.

In the embodiment of the present invention, when it is determined that the frequency band is a faulty frequency band, the frequency band data of the faulty frequency band can be determined by searching the preset frequency band data of each frequency band in the non-volatile data stored in the mobile terminal, and delete the frequency band. The frequency band data of the faulty frequency band, and restart the mobile terminal, so that the mobile terminal will realize the shielding of the faulty frequency band after restarting, and the mobile terminal will no longer use the faulty frequency band, which can effectively avoid the impact of using the faulty frequency band on the speed of network search and cell handover. And it can avoid the waste of power of the mobile terminal caused by using the faulty frequency band to try invalid communication for many times.

Please refer to FIG. 6 , which is a schematic diagram of functional modules of a processing device for faulty frequency bands in a third embodiment of the present invention. The processing device includes: a first determination module 601 , a determination and masking module 602 .

The first determination module 601 is configured to determine the transmission power of each frequency band to be detected when a faulty frequency band detection instruction is detected;

In the embodiment of the present invention, the device for processing the faulty frequency band is a part of the mobile terminal shown in FIG. 1 .

In the embodiment of the present invention, the mobile terminal will detect the faulty frequency band every preset time period, and can also perform a faulty frequency band detection in a fixed state. For example, the mobile terminal can generate a faulty frequency band immediately after each startup. The frequency band detection command enables the processing device to process the faulty frequency band after detecting the faulty frequency band detection command. Alternatively, after the mobile terminal is started, it generates a faulty frequency band detection command every N (eg, 5) hours, so that the processing device can process the faulty frequency band after detecting the faulty frequency band detection command. Therefore, it can be understood that in practical applications, the timing of generating the faulty frequency band detection instruction may be preset to start the processing device to process the faulty frequency band, which is not limited here. Wherein, the processing of the faulty frequency band by the processing device includes detecting the faulty frequency band and shielding the faulty frequency band, which will be described in detail below.

In the embodiment of the present invention, the failure of the frequency band is mainly due to the failure of the physical link corresponding to the frequency band. The physical link usually includes devices such as duplexers, filters, and power amplifiers. Any device in the physical link Any damage will cause the physical link to fail to work normally (for example, the signal cannot be sent, or the power of the sent signal does not meet the requirements), which means that the frequency band corresponding to the physical link cannot be used, and this frequency band is the faulty frequency band .

In the embodiment of the present invention, when a faulty frequency band detection instruction is detected, the first determination module 601 will determine the transmit power of each frequency band to be detected.

Wherein, the frequency band to be detected refers to the frequency band that the mobile terminal can use. Specifically, when the mobile terminal is started, it will load all the frequency bands preset in the saved non-volatile data (NV data), and only when the mobile terminal is loaded After the frequency band in NV, the frequency band can be used. Therefore, the processing device may determine all frequency bands to be detected by determining all loaded frequency bands. Since different frequency bands correspond to different transmission powers, and the mapping relationship between frequency bands and transmission powers is preset in the mobile terminal, the processing device may, after determining the frequency bands to be detected, base on the above-mentioned frequency bands and transmission power The relationship between factors determines the transmission power of each frequency band to be detected.

The determining and shielding module 602 is configured to, for each of the frequency bands, determine whether the frequency band is faulty according to the transmit power of the frequency band and the power of a feedback signal obtained by sending a signal based on the transmit power of the frequency band frequency band, and when it is determined that the frequency band is a faulty frequency band, shield the frequency band.

In the embodiment of the present invention, for each frequency band to be detected, the processing device will detect each of the frequency bands to determine whether it is a faulty frequency band, and when a certain frequency band is a faulty frequency band, shield the frequency band.

Specifically, for each frequency band in each frequency band to be detected, the determination and shielding module 602 will determine whether the frequency band is a fault frequency band according to the transmission power of the frequency band and the power of the feedback signal obtained by sending signals based on the transmission power of the frequency band , and when the frequency band is determined to be a faulty frequency band, the frequency band is blocked. For example, taking frequency band A as an example, if the transmission power of frequency band A is 23dBm, the processing device will use the physical link of frequency band A to transmit signals according to the transmission power of 23dBm, and obtain the signal obtained by transmitting signals according to the transmission power of 23dBm A feedback signal, and calculating the power of the feedback signal. After obtaining the power of the feedback signal, use the transmission power 23dBm of the frequency band A and the power of the feedback signal to determine whether the frequency band A is a fault frequency band, and when the frequency band A is determined to be a fault frequency band, shield the frequency band.

By detecting the faulty frequency band and shielding the faulty frequency band, the mobile terminal will not use the faulty frequency band, effectively avoiding the impact of using the faulty frequency band on the speed of network search and cell switching, and avoiding the problem of power waste caused by using the faulty frequency band .

In the embodiment of the present invention, taking a frequency band as an example, when the processing device detects whether the frequency band is a faulty frequency band, the sending determination module 701 will send a signal according to the transmission power of the frequency band, for example, if the transmission power of the frequency band is 23dBm, the transmission determination module 701 will first determine the physical link corresponding to the frequency band, and transmit signals through the physical link according to the transmission power of 23dBm.

Wherein, after the transmission determination module 701 transmits the signal according to the transmission power of the frequency band, the signal will reach the coupling link in the mobile terminal, and the coupling link will send the feedback signal to the transmission determination module 701, so that the transmission determination module 701 determines according to The feedback signal obtained by sending the signal at the transmission power of the frequency band, and the power of the feedback signal is obtained. It should be noted that, in the mobile terminal, the relationship between the processing device, the physical link of the frequency band, and the coupling link is: the physical links of all the frequency bands in the mobile terminal are connected to the coupling link, and the processing device can control the physical link of the frequency band. The channel sends a signal according to the specified transmission power, and the signal will pass through the coupling link connected to the physical link, and the coupling link will feed back the passing signal to the processing device, so that the processing device can determine the power of the fed back signal.

In the embodiment of the present invention, the fault determination module 702 will determine whether the frequency band is a fault frequency band according to the transmission power of the frequency band and the power of the feedback signal, and if it is determined that the frequency band is a fault frequency band, the shielding module 703 will shield the frequency band.

In the embodiment of the present invention, when a faulty frequency band detection command is detected, the transmission power of each frequency band to be detected is determined, and for each frequency band in each frequency band, a signal is sent according to the transmission power of the frequency band, and the coupling chain in the mobile terminal is determined. According to the power of the feedback signal sent by the transmission power of the frequency band, determine whether the frequency band is a fault frequency band according to the transmission power of the frequency band and the power of the feedback signal. If it is determined that the frequency band is a fault frequency band, then shield the frequency band. By detecting the faulty frequency band and shielding the faulty frequency band, the mobile terminal will not use the faulty frequency band, effectively avoiding the impact of using the faulty frequency band on the speed of network search and cell switching, and avoiding the problem of power waste caused by using the faulty frequency band .

Please refer to FIG. 8, which is a schematic diagram of the detailed functional modules of the fault determination module 702 in the fourth embodiment shown in FIG. 7 of the present invention. The fault determination module 702 includes:

A search module 801, configured to search for a correspondence between the preset transmission power and the coupling power of the coupling link, and determine the coupling power corresponding to the transmission power of the frequency band;

The second determination module 802 is configured to determine whether the frequency band is a fault frequency band according to the coupling power and the power of the feedback signal.

In the embodiment of the present invention, the second determination module 802 includes:

a calculation module 803, configured to calculate a difference between the coupling power and the power of the feedback signal;

A third determining module 804, configured to determine that the frequency band is not a faulty frequency band if the difference is within a preset range;

The fourth determining module 805 is configured to determine that the frequency band is a faulty frequency band if the difference is not within a preset range.

In the embodiment of the present invention, the corresponding relationship between the transmission power of each frequency band and the coupling power of the coupling link is preset in the mobile terminal, where the coupling power of the coupling link refers to the coupling The power of the feedback signal for link feedback.

In the embodiment of the present invention, after the processing device determines the power of the feedback signal fed back by the coupling link, the search module 801 will search for the corresponding relationship between the preset transmit power and the coupling power of the coupling link, and determine the corresponding relationship with the frequency band. The coupling power corresponding to the transmit power, and the second determination module 802 determines whether the frequency band is a fault frequency band according to the coupling power and the power of the feedback signal.

Wherein, the second determination module 802 specifically includes: the calculation module 803 calculates the difference between the coupled power and the power of the feedback signal; if the difference is within a preset range, the third determination module 804 determines that the frequency band is not a fault frequency band; if the difference is not within the preset range, the fourth determination module 805 determines that the frequency band is a faulty frequency band.

It should be noted that, in the embodiment of the present invention, when a frequency band fails, the corresponding physical link has two situations, one is that the signal cannot be sent at all, and the other is that the signal can be sent, but the power of the sent signal is far It is much smaller than the power of the signal that actually needs to be sent. Therefore, when the processing device obtains the feedback signal obtained by sending the signal based on the transmission power of the frequency band, it specifically includes: if the processing device does not receive the feedback signal fed back by the coupling link within the preset time period , it is determined that the power of the feedback signal fed back by the coupling link is zero, and if the processing device receives the feedback signal fed back by the coupling link within a preset time period, calculates the power of the feedback signal.

In the embodiment of the present invention, the coupling power corresponding to the transmission power of the frequency band can be effectively determined by searching the correspondence between the preset transmission power and the coupling power of the coupling link, and according to the coupling power and the feedback signal The power can effectively determine whether the frequency band is a fault frequency band, so as to realize the detection of the fault frequency band.

A data search module 901, configured to search for the frequency band data of each frequency band preset in the non-volatile data stored in the mobile terminal, and determine the frequency band data of the faulty frequency band;

A delete restart module 902, configured to delete the determined frequency band data of the faulty frequency band, and restart the mobile terminal.

Wherein, restarting the mobile terminal mainly considers that: when the mobile terminal is started, it needs to load the frequency band data of each frequency band in the non-volatile data, so as to use each frequency band for communication. When the mobile terminal is in the activated state, if the processing device detects the faulty frequency band and deletes the faulty frequency band, the mobile terminal will still use the faulty frequency band when using the frequency band for communication, and must restart the mobile terminal and restart Only by loading the frequency band data of the frequency band from which the faulty frequency band has been deleted can the shielding of the faulty frequency band be truly realized.

It should be noted that, in the embodiment of the present invention, before the mobile terminal is restarted, a prompt message can be sent to remind the user that the mobile terminal needs to be restarted to make the communication of the mobile terminal normal, and if a restart confirmation instruction is detected, the mobile terminal will be restarted. , if the restart cancellation instruction is detected, cancel the restart of the mobile terminal so as to meet the user's requirements.

Wherein, after restarting the mobile terminal, the mobile terminal will load the frequency band data of the frequency band from which the faulty frequency band has been deleted, so that the mobile terminal will no longer use the faulty frequency band during use, so as to complete the shielding of the faulty frequency band.

In the embodiment of the present invention, when it is determined that the frequency band is a faulty frequency band, the frequency band data of the faulty frequency band can be determined by searching the preset frequency band data of each frequency band in the non-volatile data stored in the mobile terminal, and delete the frequency band. The frequency band data of the faulty frequency band, and restart the mobile terminal, so that the mobile terminal will realize the shielding of the faulty frequency band after restarting, and the mobile terminal will no longer use the faulty frequency band, which can effectively avoid the impact of using the faulty frequency band on the network search speed and cell switching. And it can avoid the waste of power of the mobile terminal caused by using the faulty frequency band to try invalid communication for many times.
