[0054] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0055] Figure 1 This is a network frequency band switching method process shown in the embodiment of the present disclosure Figure 1 ,like Figure 1 As shown, the network frequency band switching method includes the following steps:

[0056] S11, detecting whether the current usage scenario of the terminal belongs to a preset scenario;

[0057] S12. In response to the current usage scenario belonging to the preset scenario, determining a target network frequency band based on the current usage scenario; wherein the power consumption of the target network frequency band is less than the power consumption of the current network frequency band of the terminal;

[0058] S13: Switch the network frequency band of the terminal to the target network frequency band.

[0059] In the embodiments of the present disclosure, the execution subject is a terminal that can access various communication networks (such as 4G, 5G networks) to realize communication functions such as calls or software applications, such as: User Equipment (UE), mobile devices, cellular phones, personal digital assistants (PDA), handheld devices, computing devices, vehicle-mounted devices, wearable devices, etc.; the execution subject can also be other electronic devices. If the execution subject is other electronic devices, the other electronic devices can establish a communication connection with the terminal, obtain the current usage scenario of the terminal, and determine the target network frequency band information that the terminal can switch to according to the current usage scenario of the terminal, and send the target network frequency band information to the terminal so that the terminal can switch the network to the target network frequency band for communication. In some possible implementations, the network frequency band switching method can be implemented by a processor calling a computer-readable instruction stored in a memory. The following is an example of the execution subject being a terminal.

[0060] In step S11, the current usage scenario of the terminal may include the usage scenario of the terminal in terms of geographical location, such as the user using the terminal indoors, in a park, or on a highway; the current usage scenario of the terminal may also be the usage scenario of the terminal in terms of communication status, such as the communication status when the user uses the terminal is relatively stable, or the communication status is poor. The current usage scenario of the terminal may also include the usage scenario of the application software (Application, App) in the terminal, for example, the user is using a voice call App, a short video App, or an office App. In the disclosed embodiment, the terminal may determine the current usage scenario of the terminal based on one or more of the detected terminal usage location information, communication status information, and App usage information.

[0061] In the embodiments of the present disclosure, the usage scenarios can be divided into static usage scenarios and dynamic usage scenarios, wherein the usage scenarios in which the terminal's position change is less than a preset position change threshold and / or the network's stability is greater than a preset stability level can be identified as static usage scenarios; and the usage scenarios in which the position change is greater than or equal to the preset position change threshold and / or the network's stability is less than or equal to the preset stability level are called dynamic usage scenarios. In static or dynamic usage scenarios, the terminal can run any or predetermined applications.

[0062] Generally, if the terminal switches the network frequency band in a dynamic scenario, the unstable network before the switch may cause poor communication quality and even extra power consumption. In this regard, in the embodiment of the present disclosure, the terminal can determine and switch the target network frequency band based on the static usage scenario to reduce the occurrence of poor communication quality and reduce the generation of extra terminal power consumption.

[0063] In some embodiments, the preset scenario is the aforementioned static usage scenario; in other embodiments, the preset scenario may also include a scenario in which the terminal runs a predetermined application under the static usage scenario.

[0064] In step S12, when the current usage scenario of the terminal belongs to the preset scenario, the terminal determines a target frequency band whose power consumption is less than the power consumption of the current network frequency band of the terminal based on the current usage scenario, so as to switch the network frequency band of the terminal to the target network frequency band in step S13.

[0065] Taking the running of a predetermined application as an example, one or more applications can be run simultaneously in the terminal. In some embodiments, if the terminal is in a single scenario of running an application in a static scenario, the terminal can determine the target network frequency band according to the power consumption value corresponding to the current network frequency band and the power consumption value of at least one other network frequency band associated with the usage scenario. For example, when the terminal runs a voice call application while the terminal position remains unchanged, the terminal can obtain the power consumption value under the current network frequency band and the power consumption values ​​corresponding to other network frequency bands of the terminal in the voice call scenario, and determine the network frequency band whose power consumption value among other network frequency bands is less than the power consumption value of the current network frequency band as the target network frequency band, for example, determining the smallest network frequency band as the target network frequency band.

[0066] In other embodiments, if the terminal is in a composite scenario in which multiple applications are running in a static scenario, the terminal may first select a target scenario, and then determine the target network frequency band based on the power consumption value corresponding to the current network frequency band and the power consumption value of at least one other network frequency band associated with the target scenario. Among them, the target scenario can be determined based on the priority of the usage scenario. Usually, the usage scenario with a higher degree of importance can be determined as the target scenario. When the geographical location of the terminal and the degree of network stability are consistent, the priority of the usage scenario can be divided according to the importance of the application. For example, when a user uses the Douyin App while making a voice call through the terminal, the terminal can select a more important voice call scenario as the target scenario. After determining the target scenario, the terminal will obtain the power consumption value under the current network frequency band, as well as the power consumption values ​​corresponding to other network frequency bands of the terminal in the voice call scenario, and determine the network frequency band in other network frequency bands whose power consumption value is less than the power consumption value of the current network frequency band as the target network frequency band.

[0067] In some embodiments, when the terminal determines the power consumption value corresponding to the current network frequency band, the actual power consumption value may be used as the power consumption value corresponding to the current network frequency band; in other embodiments, the terminal may determine the power consumption value corresponding to the current network frequency band based on the historical power consumption value corresponding to the current network frequency band.

[0068] In the embodiment of the present disclosure, the terminal may trigger the network frequency band switching method of the embodiment of the present disclosure in real time, or may periodically trigger the network frequency band switching method at predetermined intervals.

[0069] In related technologies, in order to provide users with the best communication quality (better network speed, better network quality, etc.), artificial intelligence and big data analysis technologies are usually used to collect and analyze user data to establish user portraits, understand users' network usage habits, and analyze and predict users' usage scenarios and usage needs, and intelligently select the best network frequency band to improve users' communication experience. For example, big data analysis methods are used to predict in advance the scenarios where network congestion may occur in subways, gatherings, etc., and combined with data such as base station signal strength, traffic load, and network speed, the best network format and resident cell are selected through artificial intelligence algorithms to minimize network congestion and improve user experience.

[0070] However, in related technologies, user scenario analysis and prediction models based on big data are often complex in structure, consume a lot of equipment resources, and have poor prediction effects for individual users. In addition, scenario analysis and prediction technologies only focus on factors such as network speed and network quality, ignoring the power consumption differences when terminals reside in different network frequency bands, which easily leads to high power consumption of terminal devices when using communication networks.

[0071] In the embodiments of the present disclosure, on the one hand, attention is paid to power consumption factors other than network speed and quality under network frequency bands, and the network frequency band of the current usage scenario is switched to a target network frequency band with lower power consumption, which is beneficial to reducing the power consumption of the terminal device during the communication process; on the other hand, the terminal determines and switches the target network frequency band based on the preset scenario, which reduces meaningless network frequency band switching, helps save the resources of the terminal device, and improves the stability of the network to which the terminal accesses.

[0072] Figure 2 This is a network frequency band switching method process shown in the embodiment of the present disclosure Figure 2 ,like Figure 2 As shown, the aforementioned step S11 includes the following steps:

[0073] S111, detecting a change in the location of the terminal and a stability of a network of the terminal;

[0074] S112, detecting whether the application currently running on the terminal is a preset application;

[0075] S113. In response to the location change of the terminal being less than a preset location change threshold, the stability of the network of the terminal being greater than a preset stability level, and the application currently running on the terminal belonging to the preset application, determining that the current usage scenario of the terminal belongs to the preset scenario.

[0076] As mentioned above, the terminal can determine and switch the target network frequency band based on the static usage scenario. In this regard, in step S111, the terminal first determines whether the terminal is in a static usage scenario, and in step S112, the terminal determines whether to run a preset application, so that in step S113, when it is determined that the terminal is in a static usage scenario and runs a preset application, it is detected whether the current usage scenario of the terminal belongs to the preset scenario.

[0077] In the embodiment of the present disclosure, the terminal determines the change in the location of the terminal by collecting the current location information of the device at a predetermined sampling interval, and determining the change in the location of the terminal based on the location information of adjacent or multiple sampling intervals. Among them, the coordinate information of the terminal can be obtained through the Global Positioning System (GPS). In the embodiment of the present disclosure, if the terminal position changes greatly (for example, greater than a preset position change threshold), it indicates that the position of the terminal has changed; if the terminal position changes little within a certain period of time (for example, less than or equal to a preset position change threshold), it indicates that the position of the terminal remains unchanged. Among them, the preset position change threshold can be the change in the terminal position, or it can be the change ratio of the terminal position.

[0078] In the embodiment of the present disclosure, the terminal determines the stability of the network in a manner that the terminal detects whether the access cell is frequently switched. If the access cell is frequently switched, it indicates that the stability of the current network of the terminal is less than a preset stability level. If the access cell is not frequently switched, it indicates that the stability of the current network of the terminal is greater than or equal to the preset stability level, wherein the preset stability level may be the number of switching times or the switching rate; or the terminal detects the current network quality parameters, and determines whether the current network is stable according to the network quality parameters. If the network quality parameters change suddenly, it indicates that the stability of the current network of the terminal is less than the preset stability level. If the network quality parameters do not change suddenly, it indicates that the stability of the current network of the terminal is greater than or equal to the preset stability level; wherein the preset stability level may be the change amount of the network quality parameters or the change rate of the network quality parameters. Wherein, the network quality parameters may include network parameters such as reference signal received power (RSRP), signal-to-noise interference ratio (SNIR), and received signal strength indicator (RSSI).

[0079] In the embodiment of the present disclosure, the terminal can determine whether the application currently running on the terminal belongs to a preset application by detecting the usage of application software, wherein the preset application can be an application that runs by default when the terminal system is running, such as a clock application of a mobile phone in a static standby state, etc., or a third-party application, such as a data traffic APP application in a non-game scenario, and also a voice application with high power consumption, etc. .

[0080] Since the terminal does not have such high requirements for network stability when it is in idle standby mode and using data traffic APP in non-gaming scenarios, determining and switching the target frequency band in this case will not affect the user experience. In addition, since voice applications consume a lot of power, determining and switching the target frequency band in this case can more specifically reduce the power consumption of the terminal.

[0081] It should be noted that, in the embodiments of the present disclosure, the preset application is not limited to the applications in the above three scenarios. For example, the preset application may also be set to an application other than a video application.

[0082] In the disclosed embodiment, the terminal first determines whether the terminal is in a static usage scenario suitable for reducing device power consumption by switching frequency bands from two perspectives: whether the location has changed and whether the network is stable. In this static usage scenario, the terminal further determines and switches the target network frequency band for the preset application, which can increase the necessity of network frequency band switching.

[0083] In some embodiments, in response to the current usage scenario belonging to the preset scenario, determining the target network frequency band based on the current usage scenario includes:

[0084] In response to the terminal's current usage scenario including multiple scenarios among the preset scenarios, the target network frequency band is determined based on a target scenario whose priority among the multiple scenarios meets a preset first priority condition; wherein the priority represents the importance of the scenario.

[0085] In the disclosed embodiment, the target scenario whose priority satisfies the preset first priority condition may refer to the scenario with the highest priority. As mentioned above, the priority may be determined based on the importance of different applications relative to the user. In the disclosed embodiment, if the terminal runs the first application in a static usage scenario, the usage scenario of the terminal is referred to as the first scenario; if the terminal runs the second application while running the first application, the usage scenario of the terminal including the operation of the second application is referred to as the second scenario, and the two scenarios belong to different scenarios.

[0086] For example, the first application is a voice call application and the second application is the Douyin App. Since the importance of the voice call application is usually higher than that of the Douyin App, the embodiment of the present disclosure can take the usage scenario including voice calls as the target scenario.

[0087] Since the network frequency bands corresponding to different scenarios may be inconsistent, if the network frequency band is switched based on the scenario with low importance, the scenario with high importance may not be executed. Therefore, in the embodiment of the present disclosure, the terminal determines the target network frequency band based on the target scenario whose priority meets the preset first priority condition among multiple scenarios, so that the terminal switches the network frequency band for the usage scenario with higher importance to optimize power consumption, that is, performs targeted network frequency band switching, which can reduce the impact of network frequency band switching on users and is more intelligent. .

[0088] Figure 3 This is a network frequency band switching method process shown in the embodiment of the present disclosure Figure 3 ,like Figure 3 As shown, the aforementioned step S12 includes the following steps:

[0089] S121. Determine, based on the current usage scenario, a first historical power consumption value corresponding to the current network frequency band of the terminal and a second historical power consumption value of each network frequency band associated with the current usage scenario;

[0090] S122: Determine, among the network frequency bands associated with the usage scenario, a network frequency band whose second historical power consumption value is smaller than the first historical power consumption value as the target network frequency band.

[0091] In the disclosed embodiment, the terminal determines the first historical power consumption value corresponding to the current network band of the terminal based on the current usage scenario. The first historical power consumption value corresponding to the network band can be determined through the network band of the terminal in the current usage scenario and the mapping relationship between the network band and the power consumption data. If the first historical power consumption value exists, then the second historical power consumption value based on the first historical power consumption value and each network band associated with the current usage scenario; if the first historical power consumption value does not exist, the power consumption of the current network band in the current usage scenario can be counted, and the power consumption result obtained by counting is stored in the mapping relationship between the aforementioned network band and the power consumption data. Among them, the mapping relationship between the network band and the power consumption data can be established based on each network band of the usage scenario and the corresponding historical power consumption data. Among them, the mapping relationship between the network band and the power consumption data can be stored in a local database of the terminal, or in other devices (such as a server), so that the terminal can obtain the first historical power consumption value through the local database and other devices.

[0092] In step S122, the terminal determines a network frequency band among the network frequency bands associated with the usage scenario, in which the second historical power consumption value is less than the first historical power consumption value, as the target network frequency band. The network frequency band corresponding to any second historical power consumption value may be determined as the target network frequency band; or the network frequency band corresponding to the lowest historical power consumption value may be determined as the target network frequency band.

[0093] As mentioned above, the terminal can determine the target network frequency band based on the actual power consumption value of the current network frequency band, or it can determine the target network frequency band based on the historical power consumption value corresponding to the current network frequency band. In the embodiment of the present disclosure, the terminal determines it based on the first historical power consumption value corresponding to the current network frequency band. Since the power consumption value corresponding to the network frequency band is accumulated during the historical use of the terminal, the first historical power consumption value corresponding to the current network frequency band can be the middle value, maximum value or average value of multiple historical power consumption values ​​corresponding to the current network frequency band. In addition, the second historical power consumption value of each network frequency band associated with the current usage scenario can also be the middle value, maximum value or average value.

[0094] It can be understood that in the embodiment of the present disclosure, since the historical power consumption values ​​(including the first historical power consumption value and the second historical power consumption value) can be values ​​obtained based on historical statistics, determining the target network frequency band based on the actual power consumption value of the current network frequency band can reduce the impact of sudden changes in the actual power consumption of the current network frequency band, thereby improving the accuracy of network frequency band switching, and the solution is simple and effective.

[0095] In some embodiments, each network frequency band associated with the usage scenario is correspondingly set with a priority, wherein network frequency bands with different second historical power consumption values ​​have different priorities;

[0096] The determining, among the network frequency bands associated with the usage scenario, a network frequency band whose second historical power consumption value is smaller than the first historical power consumption value as the target network frequency band includes:

[0097] Among the network frequency bands associated with the usage scenario, a network frequency band whose priority satisfies a preset second priority condition and whose second historical power consumption value is less than the first historical power consumption value is determined as the target network frequency band.

[0098] In the disclosed embodiment, each network frequency band associated with the usage scenario is correspondingly set with a priority, and the priority is determined based on the second historical power consumption value. For example, in the same usage scenario, the priority of each network frequency band is negatively correlated with the second historical power consumption value corresponding to the network frequency band, and the second historical power consumption value having a large priority is low. In the disclosed embodiment, the priority satisfies the preset second priority condition, for example, the highest priority network frequency band whose second historical power consumption value is less than the first historical power consumption value is determined as the target network frequency band.

[0099] In the disclosed embodiment, each network frequency band associated with the usage scenario is set with a priority based on the second historical power consumption value, so as to facilitate determining the target network frequency band based on the priority, which can help determine the target frequency band that can better save terminal power consumption.

[0100] In some embodiments, determining, among the network frequency bands associated with the usage scenario, a network frequency band whose second historical power consumption value is less than the first historical power consumption value as the target network frequency band includes:

[0101] Among the network frequency bands associated with the usage scenario, a network frequency band whose current network quality meets a preset quality condition and whose second historical power consumption value is less than the first historical power consumption value is determined as the target network frequency band.

[0102] In the disclosed embodiment, the preset quality condition may be set based on the switching situation of the cell currently accessed by the network frequency band, or may be set based on the current network quality parameter of the network frequency band, or may be set from both perspectives. For example, if the switching frequency of the cell currently accessed by the network frequency band is less than the preset switching frequency, and / or the degree of change of the current network quality parameter of the network frequency band is less than the preset degree threshold, the terminal determines that the current network quality of the network frequency band meets the preset quality condition.

[0103] In the disclosed embodiment, the terminal determines as the target network frequency band a network frequency band whose current network quality satisfies a preset quality condition and whose second historical power consumption value is less than the first historical power consumption value among the network frequency bands associated with the usage scenario. This is beneficial for reducing the impact on the terminal network quality while reducing the power consumption of the terminal, reducing the occurrence of network quality deterioration caused by network frequency band switching, and improving the stability of the network switching method.

[0104] In some embodiments, determining, based on the current usage scenario, a first historical power consumption value corresponding to the current network frequency band of the terminal and a second historical power consumption value of each network frequency band associated with the current usage scenario includes:

[0105] Based on the pre-stored mapping relationship associated with the current usage scenario, determine the first historical power consumption value corresponding to the current network frequency band of the terminal and the second historical power consumption value of each network frequency band associated with the usage scenario; wherein the mapping relationship includes a mapping relationship between network frequency bands and power consumption values.

[0106] In the disclosed embodiment, the mapping relationship associated with the current usage scenario pre-stored in the terminal may include the correspondence between the network frequency band and the power consumption value, and may also include the priority of the usage scenario and the priority of the historical power consumption of the network frequency band. Among them, the mapping relationship can be stored in the local database of the terminal, and can also be stored in other electronic devices that establish a communication connection with the terminal. In the disclosed embodiment, the data in the mapping relationship associated with the current usage scenario pre-stored can be obtained based on the statistics of the network frequency band and the power consumption data within the network frequency band when the usage scenario is running during historical use. In addition, in order to ensure the validity and timeliness of the data, the pre-stored mapping relationship associated with the current usage scenario can be updated regularly.

[0107] In the disclosed embodiment, the terminal first determines a first historical power consumption value corresponding to the current network frequency band based on the current usage scenario and the current network frequency band based on a pre-stored mapping relationship associated with the current usage scenario, and then determines the data in the mapping relationship whose power consumption is less than the first historical power consumption value as the second historical power consumption value based on the first historical power consumption value.

[0108] In the disclosed embodiment, the terminal determines the first historical power consumption value and the second historical power consumption value based on a pre-stored mapping relationship associated with the current usage scenario. Compared with real-time calculation based on the current usage scenario, the real-time calculation amount of the terminal device is reduced and the network switching method is simplified.

[0109] In some embodiments, the method further comprises:

[0110] During the historical use of the terminal, determining a network frequency band in which the terminal operates in the usage scenario and a power consumption value within the network frequency band;

[0111] In response to the difference between the power consumption value of the terminal within the network frequency band and the preset power consumption value corresponding to the usage scenario being less than a preset difference threshold, the mapping relationship associated with the usage scenario is generated based on the network frequency band and the power consumption value corresponding to the network frequency band.

[0112] In the disclosed embodiment, the network frequency band of the terminal and the power consumption value within the network frequency band when the terminal is running in the usage scenario can be determined during the historical use of the terminal. For example, the terminal can start the power consumption statistics service, count the power consumption corresponding to the current network frequency band in the usage scenario, and store the result in the mapping relationship associated with the current usage scenario. Among them, the power consumption can be the total power consumption, average power consumption, etc. of the frequency band used in the usage scenario.

[0113] In the disclosed embodiment, the power consumption value of the terminal in the network frequency band is compared with the preset power consumption value corresponding to the usage scenario. If the difference is less than the preset difference threshold, a mapping relationship associated with the usage scenario is generated based on the network frequency band and the power consumption value corresponding to the network frequency band; if the difference is greater than or equal to the preset difference threshold, the power consumption value is considered invalid and the mapping relationship associated with the usage scenario is not generated. The preset power consumption value corresponding to the usage scenario can usually be set with reference to the data given by each network operator.

[0114] In the disclosed embodiment, when generating a mapping relationship for a usage scenario, the terminal verifies the validity of the statistical power consumption value within the network frequency band based on a preset power consumption value, and generates a mapping relationship between the network frequency band and the power consumption value based only on the valid power consumption value, which is beneficial to improving the accuracy of the mapping relationship and thereby improving the accuracy of the network frequency band switching method.

[0115] Take a mobile phone as an example. The mobile phone has a built-in communication chip. Under normal circumstances, the activation state of the communication chip allows the mobile phone to connect and stay on the network to use communication services. It should be noted that if the mobile phone user is in a scene with complex and changeable signal conditions such as highways and high-speed railways, frequent network frequency band switching will cause problems such as poor communication quality and additional power consumption. In this regard, in the embodiments of the present disclosure, attention is paid to the optimization of power consumption of the resident network frequency band when the mobile phone is in a static usage scenario (preset scenario).

[0116] In this embodiment, the usage scenario of the mobile phone is judged (that is, whether the current usage scenario of the detection terminal in the embodiment of the present disclosure belongs to the preset scenario). The mobile phone can be based on signaling messages and GPS and other technologies. For example, the call management service (TelephonyManager) and location management (LocationManager) can be used to obtain data related to the network stability and location change of the mobile phone. When the network stability of the mobile phone is good and the location change is small, it is determined that the mobile phone is in a static usage scenario; otherwise, the mobile phone is considered to be in a dynamic usage scenario.

[0117] In this embodiment, when the mobile phone is in a static usage scenario, the Band power consumption detection and switching service is turned on (that is, in the embodiment of the present disclosure, in response to the current usage scenario belonging to the preset scenario, the target network frequency band is determined based on the current usage scenario and the frequency band is switched). It should be noted that in order to enhance the generalization performance of the embodiment of the present disclosure, the static usage scenario can be set to at least include static standby, voice calls (set as the highest priority usage scenario), and the use of non-game scenario apps, and the Band power consumption detection and switching service is turned on in the above three usage scenarios. It should be noted that when there is a superposition of usage scenarios, the highest priority scenario is used as the target scenario for power consumption statistics and optimization. For example, if the user is on a call and brushing Douyin, power consumption statistics and Band selection are performed based on the call scenario.

[0118] In this embodiment, the mobile phone must meet the following two conditions to switch the Band:

[0119] 1. The mobile phone enters the three usage scenarios set above, and there is a historical average power consumption record of the communication module (radio) of the switchable target band in the corresponding usage scenarios;

[0120] 2. The signal quality of the target band is good, reducing the impact on call quality and data activity quality.

[0121] In this embodiment, the Band power consumption detection and switching service includes the following steps:

[0122] Step 1. Get the current mobile phone usage scenario S and the frequency band Band B1.

[0123] The mobile phone can search the local Band power consumption database to determine whether the power consumption data of Band B1 already exists in the scene S. If not, go to step 2 to count the power consumption; if yes, go to step 3.

[0124] Step 2. Start the power consumption statistics service of Band B1 in scenario S.

[0125] Based on the power consumption service (BatteryStats API), the mobile phone can count the power consumption and usage time of the communication module in scenario S, calculate the average power consumption current value C of the communication module and store it in the local Band power consumption database. When storing the power consumption data, the search priority P1 is set for Band B1 according to the power consumption current value C. In addition, the power consumption current value can also be prioritized, for example, the priority of the Band with lower power consumption in the same scenario can be set to high.

[0126] Step 3: The mobile phone queries the Band power consumption database to determine whether there are other Bands whose power consumption of the communication module is better than the current Band B1 in scenario S.

[0127] If there are other bands that are better than the current Band B1, and the number of bands is greater than or equal to 1, it indicates that there is a switchable target band, and the process goes to Step 4.

[0128] Step 4: The mobile phone can search for other bands with better power consumption as recorded in Step 3 in order of priority, and set the switching priority P2 for the bands whose signal quality meets the set threshold. When the search is completed, the band with the highest P2 priority is set as the target band, and the mobile phone is switched to the target band; if there is no P2 priority band, no band switching action is performed.

[0129] In this embodiment, the local Band power consumption database of the mobile phone is set and maintained (ie, in the embodiment of the present disclosure, during the historical use of the terminal, a mapping relationship associated with the usage scenario is generated based on the network frequency band and the power consumption value corresponding to the network frequency band).

[0130] It should be noted that this embodiment relies heavily on the historical power consumption records of the communication module of the mobile phone on different bands. To this end, the validity of the power consumption data can be improved from the following two perspectives:

[0131] In this embodiment, the mobile phone can regularly collect and update power consumption data to improve the timeliness of data update, for example, regularly (every three days) update the existing power consumption data of the mobile phone in different scenarios and different bands.

[0132] In this embodiment, a historical experience value H of power consumption when the scene S resides in a specific Band is preset, and the Band power consumption data C measured in Step 2 is compared with H, and the power consumption value with a difference within the threshold is stored, otherwise, the measured value is discarded.

[0133] In this embodiment, the mobile phone detects and switches the Band in a static usage scenario so that the mobile phone preferentially resides in the Band that meets the communication quality conditions and has lower power consumption performance, thereby further reducing the power consumption of the mobile phone and improving the battery life performance of the mobile phone without affecting the quality of the communication network.
