Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a power switching method, apparatus, device, and storage medium. Background Technology

[0002] Currently, with the rapid development of mobile terminals, more and more users are using mobile terminals for communication. The electromagnetic wave energy generated by the radio frequency transmission power of mobile terminals such as smartphones can be absorbed by the human body; this absorption rate is called SAR (Specific Absorption Rate). To assess the electromagnetic radiation safety of mobile terminals, different countries and regions have specified different regulatory requirements for this absorption rate according to their own standards. Existing mobile terminal manufacturers need to configure different radio frequency parameter profiles or make hardware adjustments for models sold in different markets, leading to increased costs. Alternatively, they can uniformly set the transmission power of mobile terminals to a lower level to ensure compliance, but this results in a decrease in communication performance. These solutions are prone to misjudgment or cannot accurately meet the regulatory requirements of various regions in border areas and scenarios with overlapping signal coverage.

[0020] Currently, with the rapid development of mobile terminals, more and more users are using mobile terminals for communication. The electromagnetic wave energy generated by the radio frequency transmission power of mobile terminals such as smartphones can be absorbed by the human body; this absorption rate is called SAR (Specific Absorption Rate). To assess the electromagnetic radiation safety of mobile terminals, different countries and regions have specified different regulatory requirements for this absorption rate according to their own standards. Existing mobile terminal manufacturers need to configure different radio frequency parameter profiles or make hardware adjustments for models sold in different markets, leading to increased costs.

[0026] This application provides a power switching method, apparatus, device, and computer-readable storage medium, which will be described in detail below.

[0027] It will be understood by those skilled in the art that Figure 1 The application environment shown is only one application scenario related to the solution of this application and does not constitute a limitation on the application scenario of this application. Other application environments may include more than one application scenario.

It is understood that the scenario of this power switching method may also include one or more power switching devices, which is not limited here. The power switching device 100 may also include a memory for storing candidate power parameter sets and other data.

[0028] It should be noted that, Figure 1 The schematic diagram of the power switching method shown is merely an example. The scenarios of the power switching method described in the embodiments of the present invention are for the purpose of more clearly illustrating the technical solutions of the embodiments of the present invention, and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention.

[0029] Based on the scenarios described above regarding the power switching method, various embodiments of the power switching method disclosed in this invention are proposed.

[0030] like Figure 2 As shown, Figure 2 This is a flowchart illustrating one embodiment of the power switching method in this application. The power switching method includes the following steps 201 to 204: 201. In response to a power switching event for the target mobile terminal, collect the multimodal geographic information of the target mobile terminal; The power switching method in this embodiment is applied to a power switching device. The type and number of power switching devices are not specifically limited. That is, the power switching device can be one or more target smart terminals capable of communication interaction. Optionally, the target mobile terminal is a mobile terminal that stores multiple (two or more) candidate power parameter sets for adjusting the terminal's transmit power. That is, the target mobile terminal is capable of dynamically loading and activating a specified candidate power parameter set to dynamically control the terminal's transmit power. The candidate power parameter set is a configuration combination containing the maximum allowable transmit power upper limit values ​​for each frequency band and channel under the wireless communication standards (e.g., Wi-Fi and cellular networks) supported by the target mobile terminal, used to control the upper limit of the RF front-end's transmit power. For example, in one specific embodiment, the target mobile terminal stores multiple candidate power parameter sets to adjust the terminal's transmit power for different SAR standard regions. Optionally, in other embodiments, the candidate power parameter set can further set different maximum transmit power upper limit values ​​for different usage scenarios of the target mobile terminal.

[0031] Optionally, the power switching event is an operational event that drives the target mobile terminal to perform location identification and dynamically adjust the terminal's transmission power. This power switching event can be triggered by various methods. For example, it can be triggered by scenarios such as cellular network changes, changes in location information, system status, or user interaction.

[0032] Optionally, the multimodal geographic information refers to geographic information representing the location of the target mobile terminal obtained using multiple positioning methods, which serves as an information source for determining the terminal location information of the target mobile terminal. In one specific embodiment, the multimodal geographic information includes any one or more of operator location information, physical location information, and wireless location information.

[0033] Optionally, operator location information refers to terminal location information obtained through operator networks to map the geographic information of the terminal's location. Optionally, in a specific embodiment, the operator location information is a Mobile Country Code (MCC) and / or a Mobile Network Code (MNC).

[0034] The physical location information is the terminal location information obtained by physically locating the target mobile terminal to obtain the corresponding latitude and longitude coordinates and then processing the information. Optionally, this physical location information can be GNSS (Global Navigation Satellite System) positioning coordinate information or other physical location information.

[0035] The wireless location information is terminal location information obtained by processing the radio access identifier of the target mobile terminal. Optionally, in one specific embodiment, the wireless location information may be the registration country information mapped by the radio access identifier.

[0036] Optionally, when the terminal detects a change in the mobile network parameters of the target mobile terminal during operation, a power switching event for the target mobile terminal is triggered. The mobile network parameters include any one or more of the following: country code, mobile network code, and serving cell identifier. Scenarios involving changes in mobile network parameters include: the target mobile terminal registering for international roaming, the target mobile terminal switching to a serving cell, and the target mobile terminal detecting a change in its operator location information. For example, in one specific embodiment, when the target mobile terminal detects and registers with a new country code or mobile network code, it is determined that the target mobile terminal is registering for international roaming, triggering a power switching event for the target mobile terminal. In another specific embodiment, when the target mobile terminal detects a change in the serving cell identifier of the serving base station, and this serving cell identifier is different from the serving cell identifier of the previous serving base station, it is determined that the target mobile terminal is switching to a cell, triggering a power switching event for the target mobile terminal.

[0037] Optionally, the terminal may also trigger a power switching event for the target mobile terminal when it detects that the difference in positioning distance between the current positioning information and the historical positioning information of the target mobile terminal exceeds a preset distance difference threshold. That is, the target mobile terminal can also be located using physical positioning to obtain its current positioning information, and the previous positioning information is identified as historical positioning information. The absolute value of the distance difference between the current positioning information and the historical positioning information is calculated as the positioning distance difference, and this difference is compared with a pre-configured preset distance difference threshold to determine whether to trigger a power switching event for the target mobile terminal.

[0038] Optionally, if the positioning distance difference exceeds the preset distance difference threshold, a power switching event for the target mobile terminal is triggered.

[0039] Optionally, to further improve the accuracy of power switching event triggering, the target mobile terminal further acquires the historical area identifier from historical location information and the current area identifier from current location information. If the location distance difference exceeds the preset distance difference threshold, and the historical area identifier from historical location information and the current area identifier from current location information are different, a power switching event is triggered for the target mobile terminal. The historical area identifier is the identifier information in historical location information that represents the region where the target mobile terminal is located. The current area identifier is the identifier information in current location information that represents the region where the target mobile terminal is located. Optionally, the historical area identifier and the current area identifier can be any one or more of administrative region identifiers, administrative region codes, and administrative boundary vector data.

[0040] Optionally, the terminal can also trigger a power switching event for the target mobile terminal when it detects a change in the SIM card status of the target mobile terminal. For example, SIM card status change scenarios include: the target mobile terminal reading the SIM card during startup or restart, and the target mobile terminal inserting or removing a new SIM card. That is, a power switching event for the target mobile terminal is triggered when the target mobile terminal performs a system startup or restart, or when the target mobile terminal reads the SIM card, or when the target mobile terminal inserts or removes a new SIM card.

[0041] Optionally, in other embodiments, when the target mobile terminal is in a conservative handover strategy, the terminal can also receive a location modification command to trigger a power switching event for the target mobile terminal. That is, after the target mobile terminal switches to a more conservative terminal transmit power in a subsequent step, the user manually modifies the terminal location information, thereby triggering a power switching event for the target mobile terminal.

[0042] Optionally, after receiving the power switching event, the target mobile terminal can also locate itself using multiple positioning methods to obtain multimodal geographic information of the target mobile terminal, and then accurately determine the terminal location information of the target mobile terminal in subsequent steps using the multimodal geographic information.

[0043] Optionally, the target mobile terminal uses its operator network to map the operator location information corresponding to the target mobile terminal. That is, the target mobile terminal reads the mobile country code and / or mobile network code corresponding to the operator network and maps the mobile country code and / or mobile network code to an administrative region identifier to obtain the operator location information corresponding to the target mobile terminal.

[0044] Optionally, the target mobile terminal can also perform inverse analysis of its current latitude and longitude to obtain its physical location information. That is, the target mobile terminal can obtain its current latitude and longitude through physical positioning and then convert it into administrative region information (such as the country and city) as its physical location information through inverse analysis. Optionally, in a specific embodiment, this physical positioning method is GNSS positioning. The current latitude and longitude are coordinate information used in a geographic coordinate system to identify the location of the target mobile terminal.

[0045] Optionally, the target mobile terminal further maps its radio access identifier to obtain its radio location information. Specifically, the target mobile terminal queries the currently accessed wireless network to obtain the corresponding radio access identifier (BSSID, Basic Service Set Identifier), and queries the access identifier database to map the wireless network registration address corresponding to the radio access identifier in the database. This wireless network registration address is then used as the target mobile terminal's radio location information. In one specific embodiment, the radio access identifier is the physical MAC address of the target mobile terminal as a radio access point. The wireless network registration address is data information representing the registration address of the wireless access point corresponding to the radio access identifier.

[0046] Optionally, the target mobile terminal may obtain multimodal geographic information by identifying any one or more of the operator location information, the physical location information, and the wireless location information as the target mobile terminal.

[0047] 202. Determine the terminal location information of the target mobile terminal based on the multimodal geographic information and the corresponding location confidence level; Optionally, after acquiring the multimodal geographic information, the target mobile terminal may also determine its terminal location information based on the multimodal geographic information and the corresponding location confidence level.

[0048] Optionally, the terminal location information is location information used to indicate the administrative region where the target mobile terminal is located. This terminal location information is determined by evaluating the corresponding location confidence obtained through cross-verification of multiple multimodal geographic information sources. Optionally, the national competition terminal location information includes first terminal location information that can uniquely identify the administrative region where the target mobile terminal is located, and second terminal location information that cannot uniquely identify the administrative region where the target mobile terminal is located. That is, the first location information is location information that uniquely points to the administrative region where the target mobile terminal is located. The second terminal location information is location information that cannot uniquely point to the administrative region where the target mobile terminal is located.

[0049] Optionally, the location confidence score is a rating index characterizing the reliability of the location information for each multimodal geographic information. Optionally, in a specific embodiment, the location confidence score is jointly determined by each multimodal geographic information. The location confidence score includes a first confidence score and a second confidence score. The first confidence score is a confidence rating index characterizing that the location information is reliable location information. The second confidence score is a confidence rating index characterizing that the location information is unreliable location information.

[0050] Optionally, the target mobile terminal determines its candidate location information based on one or more of the operator location information, physical location information, and wireless location information in the multimodal geographic information. The candidate location information is the positioning information corresponding to each multimodal geographic information. That is, the target mobile terminal determines any one or more of the operator location information, physical location information, and wireless location information in the multimodal geographic information as possible candidate location information.

[0051] Optionally, the target mobile terminal can also determine the location confidence of each candidate location information based on the number of first information sources that locate the same location information in the candidate location information and the number of second information sources that generate the candidate location information, and determine the terminal location information corresponding to the target mobile terminal based on the candidate location information and the location confidence corresponding to the candidate location information.

[0052] 203. Determine the target power parameter set of the target mobile terminal based on the terminal location information and the candidate power parameter set; Optionally, after determining the terminal location information of the target mobile terminal, a target power parameter set for the target mobile terminal is also determined based on the terminal location information and the candidate power parameter set. That is, the target mobile terminal can select a target power parameter set suitable for the current administrative region from the candidate power parameter set according to the terminal location information.

[0053] Optionally, the target power parameter set is a candidate power parameter set to be switched by the target mobile terminal. This is to enable dynamic loading and activation of a specified candidate power parameter set to dynamically control the terminal's transmit power. The candidate power parameter set is a configuration combination containing the maximum allowable transmit power upper limits for each frequency band and channel under the wireless communication standards (e.g., Wi-Fi and cellular networks) supported by the target mobile terminal, used to control the upper limit of the RF front-end's transmit power.

[0054] Optionally, the target mobile terminal is configured with multiple power switching strategies corresponding to the terminal location information. After determining the terminal location information, the power switching strategy corresponding to the terminal location information is selected, and the target power parameter set in the candidate power parameter set is selected through the power switching strategy.

[0055] Optionally, the power switching strategy is a set of rules used to guide the target mobile terminal to select a target power parameter set. In one specific embodiment, the power switching strategy includes a precise switching strategy and a compliant switching strategy corresponding to the first terminal location information. The precise switching strategy is a switching strategy that uses the candidate power parameter set corresponding to the first terminal location information as the target parameter set. The compliant switching strategy is a switching strategy that determines the candidate power parameter set whose transmit power upper limit is lower than the transmit power upper limit corresponding to other candidate power parameter sets as the target power parameter set. That is, under the compliant switching strategy, the candidate power parameter set with the lowest transmit power upper limit (i.e., the most stringent SAR) is selected as the target power parameter set to ensure SAR compliance.

[0056] Optionally, in one specific embodiment, if the terminal determines that the terminal location information is the second terminal location information, then the power switching strategy of the target mobile terminal is determined to be a conservative switching strategy, and the candidate power parameter set is traversed based on the conservative switching strategy. The candidate power parameter set whose upper limit of transmission power is lower than the upper limit of transmission power corresponding to other candidate power parameter sets is determined as the target power parameter set of the target mobile terminal.

[0057] 204. Adjust the terminal transmission power of the target mobile terminal using the target power parameter set to obtain the power switching result.

[0058] Optionally, after determining the target power parameter set of the target mobile terminal, the terminal transmit power of the target mobile terminal is also adjusted using the target power parameter set to obtain the power switching result. That is, the target mobile terminal loads and activates the target power parameter set from the power parameter memory storing the target power parameter set to control the upper limit of the transmit power of the radio frequency front end, thereby adjusting the terminal transmit power of the target mobile terminal and obtaining the power switching result.

[0059] Optionally, after determining the candidate power parameter set with the lowest transmit power upper limit (i.e., the most stringent SAR) using a conservative handover strategy, the target mobile terminal, to avoid misjudgment, also displays a corresponding power handover notification on the display interface and generates a location verification control corresponding to the power handover notification for user interaction. Based on the user interaction results, it further determines whether to update the target power parameter set. The power handover notification reads: "To comply with the security standards of the possible location area, the device has automatically optimized wireless performance." The location verification control displays the text: "I confirm that my current location is xxx."

[0060] Optionally, when a user frequently updates the location information of any terminal, the terminal identifies the administrative region corresponding to the location information as a conflict region and adjusts the power switching strategy for that conflict region.

[0061] In this embodiment, the power switching device, in response to a power switching event for a target mobile terminal, collects the multimodal geographic information of the target mobile terminal; determines the terminal location information of the target mobile terminal based on the multimodal geographic information and the corresponding location confidence level; determines the target power parameter set of the target mobile terminal based on the terminal location information and a candidate power parameter set; and adjusts the terminal transmit power of the target mobile terminal using the target power parameter set to obtain the power switching result. This achieves the setting of multiple candidate power parameter sets in the target mobile terminal, and when the target mobile terminal triggers a power switching event via various triggering methods, it collects the multimodal geographic information of the target mobile terminal. The multimodal geographic information is used to accurately assess the location of the target mobile terminal to determine its terminal location information. Based on this location information, the device selects the target power parameter set that matches the target mobile terminal for power switching. This allows the target mobile terminal to automatically switch its transmit power according to its current location information without affecting its communication performance, enabling the terminal to adaptively meet the radio frequency compliance requirements of different regions, thereby maximizing the communication performance of the target mobile terminal and meeting the user's terminal communication needs.

[0062] like Figure 3 As shown, Figure 3 A flowchart illustrating one embodiment of the power switching method for determining terminal location information provided in this application is shown below. Figure 3 In the illustrated embodiment, the power switching method further includes steps 301 to 303: 301. If the number of first information sources corresponding to the same location information in the candidate location information is greater than or equal to the first information source threshold, then the location confidence of the same location information is determined as the first confidence. 302. If the number of first information sources with the same location information in the candidate location information is less than the first information source threshold, and / or the number of second information sources of the candidate location information is less than or equal to the second information source threshold, then the location confidence level corresponding to the candidate location information is determined as the second confidence level. 303. The candidate location information with a location confidence level of first confidence level is determined as the terminal location information.

[0063] Based on the above embodiments, in this embodiment, after the target mobile terminal obtains the multimodal geographic information, it also determines the terminal location information of the target mobile terminal based on the multimodal geographic information and the corresponding location confidence.

[0064] Optionally, the target mobile terminal compares each candidate location information to determine the number of identical location information and the number of first information sources within the candidate location information. The identical location information refers to candidate location information pointing to the same administrative region. The number of first information sources refers to the number of identical location information.

[0065] Optionally, the target mobile terminal also pre-sets a first information source threshold for evaluating whether the same location information is credible, and compares the number of first information sources with the first information source threshold to determine the location credibility of the same location information.

[0066] Optionally, if the number of first information sources corresponding to the same location information in the candidate location information is greater than or equal to the first information source threshold, then the location confidence of the same location information is determined as the first confidence level characterizing the location information as credible location information.

[0067] Optionally, if the number of first information sources containing the same location information among the candidate location information is less than the first information source threshold, then the location confidence level corresponding to the candidate location information is determined as the second confidence level characterizing the location information as unreliable. That is, if there are few identical location information among the candidate location information, and different candidate location information points to different administrative regions, resulting in contradictions between information sources, the confidence level of the identical location information is low.

[0068] Optionally, if the number of second information sources for the candidate location information is less than or equal to the second information source threshold, then the location confidence level corresponding to the candidate location information is determined as the second confidence level characterizing the location information as unreliable. Here, the number of second information sources represents the number of information sources representing available location information in the candidate location information. The second information source threshold is a threshold for assessing whether there is insufficient information from the information sources of the candidate location information. That is, when the number of second information sources in the candidate location information is small, the terminal determines the location confidence level of the candidate location information to be a low-confidence second confidence level.

[0069] Optionally, after the target mobile terminal determines each candidate location information, the candidate location information corresponding to the first confidence level is determined as the first terminal location information. If the first confidence level is not present in the location confidence level of the candidate location information, then the terminal location information of the target mobile terminal is determined as the second terminal location information.

[0070] For example, in one specific embodiment, if there are multiple available information sources in the candidate location information pointing to the same administrative region A, and the number of first information sources of the same location information pointing to administrative region A in the candidate location information is greater than the first information source threshold, the target mobile terminal determines the terminal location information as the first terminal location information, and the first terminal location information is administrative region A.

[0071] For example, in another specific embodiment, if the candidate location information all point to different administrative regions or the number of second information sources corresponding to the effective information sources of the candidate location information is small, then the target mobile terminal determines that it cannot evaluate the real terminal location information and determines the terminal location information as the second terminal location information.

[0072] In this embodiment, the terminal determines the location confidence level of the same location information as a first confidence level if the number of first information sources corresponding to the same location information in the candidate location information is greater than or equal to a first information source threshold; if the number of first information sources corresponding to the same location information in the candidate location information is less than the first information source threshold, and / or the number of second information sources corresponding to the candidate location information is less than or equal to a second information source threshold, the location confidence level corresponding to the candidate location information is determined as a second confidence level; the candidate location information with a location confidence level of the first confidence level is determined as the terminal location information. This enables multimodal evaluation of the location area of ​​the target mobile terminal, improving the positioning accuracy of the target mobile terminal.

[0073] like Figure 4 As shown, Figure 4 A flowchart illustrating an embodiment of the power switching method provided in this application for determining a target power parameter set is shown below. Figure 4 As shown, the power switching method further includes steps 401 to 403: 401. If the terminal location information is the first terminal location information, then the power switching strategy of the target mobile terminal is determined to be a precise switching strategy. 402. Based on the precise switching strategy, read the administrative region code information corresponding to the location information of the first terminal; 403. The candidate power parameter set corresponding to the administrative region code information in the candidate power parameter set is determined as the target power parameter set of the target mobile terminal.

[0074] Based on the above embodiments, in this embodiment, after determining the terminal location information of the target mobile terminal, a target power parameter set for the target mobile terminal is also determined based on the terminal location information and the candidate power parameter set. That is, the target mobile terminal can select a target power parameter set suitable for the current administrative region from the candidate power parameter set according to the terminal location information.

[0075] If the target mobile terminal determines that the location information is the first terminal location information, then the power switching strategy of the target mobile terminal is determined to be a precise switching strategy. The precise switching strategy is a switching strategy that uses the candidate power parameter set corresponding to the first terminal location information as the target parameter set.

[0076] Optionally, after determining the precise handover strategy, the target mobile terminal also reads the administrative region code information corresponding to the location information of the first terminal based on the precise handover strategy. The administrative region code information is the region code information representing the administrative region where the target mobile terminal is located.

[0077] Optionally, after obtaining the administrative region code information, the target mobile terminal also uses the administrative region code information to match the candidate power parameter set, and determines the candidate power parameter set corresponding to the administrative region code information as the target power parameter set of the target mobile terminal.

[0078] Optionally, after determining the target power parameter set of the target mobile terminal, the terminal transmit power of the target mobile terminal is also adjusted using the target power parameter set to obtain the power switching result. That is, the target mobile terminal loads and activates the target power parameter set from the power parameter memory storing the target power parameter set to control the upper limit of the transmit power of the radio frequency front end, thereby adjusting the terminal transmit power of the target mobile terminal and obtaining the power switching result.

[0079] In this embodiment, the power switching device determines the power switching strategy of the target mobile terminal as a precise switching strategy if the terminal location information is the first terminal location information; based on the precise switching strategy, it reads the administrative region code information corresponding to the first terminal location information; and determines the candidate power parameter set corresponding to the administrative region code information in the candidate power parameter set as the target power parameter set of the target mobile terminal. This enables accurate identification of the target power parameter set of the target mobile terminal even with high-confidence terminal location information, thereby improving the accuracy of subsequent terminal power parameter adjustments.

[0083] In one possible implementation of this embodiment, the power switching device determines the terminal location information corresponding to the target mobile terminal based on the candidate location information and the location confidence level corresponding to the candidate location information, including: If the number of first information sources corresponding to the same location information in the candidate location information is greater than or equal to the first information source threshold, then the location confidence of the same location information is determined as the first confidence. If the number of first information sources with the same location information in the candidate location information is less than the first information source threshold, and / or the number of second information sources of the candidate location information is less than or equal to the second information source threshold, then the location confidence level corresponding to the candidate location information is determined as the second confidence level. Candidate location information with a location confidence level of 1 is determined as terminal location information.

[0084] In one possible implementation of this embodiment, the power switching device terminal location information includes first terminal location information, which is location information that uniquely points to the administrative region where the target mobile terminal is located; Determining the target power parameter set of the target mobile terminal based on the terminal location information and the candidate power parameter set includes: If the terminal location information is the first terminal location information, then the power switching strategy of the target mobile terminal is determined to be the precise switching strategy; Based on the precise switching strategy, the administrative region code information corresponding to the first terminal location information is read; The candidate power parameter set corresponding to the administrative region code information in the candidate power parameter set is determined as the target power parameter set of the target mobile terminal.

[0085] In one possible implementation of this embodiment, the power switching device terminal location information includes second terminal location information, which is location information that cannot uniquely point to the administrative region where the target mobile terminal is located; Determining the target power parameter set of the target mobile terminal based on the terminal location information and the candidate power parameter set includes: If the terminal location information is the second terminal location information, then the power switching strategy of the target mobile terminal is determined to be a conservative switching strategy. Based on the conservative handover strategy, the candidate power parameter set is traversed, and the candidate power parameter set whose upper limit of transmission power is lower than the upper limit of transmission power of the corresponding candidate power parameter set is determined as the target power parameter set of the target mobile terminal.

[0086] In one possible implementation of this embodiment, before the power switching device responds to a power switching event for the target mobile terminal, it further includes: When a change in the mobile network parameters of the target mobile terminal is detected, a power switching event for the target mobile terminal is triggered. And / or, when the difference in positioning distance between the current positioning information and the historical positioning information of the target mobile terminal is detected to exceed a preset distance difference threshold, a power switching event for the target mobile terminal is triggered; And / or, when a change in the SIM card status of the target mobile terminal is detected, a power switching event for the target mobile terminal is triggered; And / or, when the target mobile terminal is in a conservative handover strategy, receive a location modification instruction to trigger a power switching event for the target mobile terminal.

Based on the multimodal geographic information and corresponding location confidence, it determines the terminal location information of the target mobile terminal. Based on the terminal location information and a candidate power parameter set, it determines the target power parameter set of the target mobile terminal. The device then adjusts the terminal transmit power of the target mobile terminal using the target power parameter set to obtain the power switching result. This allows for the setting of multiple candidate power parameter sets in the target mobile terminal. When a power switching event is triggered by the target mobile terminal through various triggering methods, the device collects the multimodal geographic information of the target mobile terminal. This multimodal geographic information is used to accurately assess the location of the target mobile terminal to determine its terminal location information. Based on this location information, the device selects the target power parameter set that matches the target mobile terminal for power switching. This enables the target mobile terminal to automatically switch its transmit power according to its current location information without affecting its communication performance. Consequently, the terminal can adaptively meet the radio frequency compliance requirements of different regions, maximizing its communication performance and satisfying the user's communication needs.
