Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts shall fall within the scope of protection of this application.

[0026] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0027] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] The following first explains the key concepts related to the embodiments of this application:

[0029] The total radiated power (TRP) is obtained by integrating and averaging the transmitted power over the entire radiation sphere for the radiation performance emission parameter. It reflects the transmitted power of the entire mobile phone and is related to the transmitted power of the mobile phone in the conduction case and the antenna radiation performance.

[0030] The Specific Absorption Ratio (SAR) refers to the electromagnetic radiation energy absorbed by a unit mass of a substance per unit time. The lower the SAR value, the smaller the amount of electromagnetic radiation absorbed by the brain of the mobile terminal. In China, the network access requirement for the SAR test of mobile terminals by the Ministry of Industry and Information Technology is that the average SAR of any 10 g of biological tissue for any continuous 6 minutes shall not exceed 2.0 W / kg.

[0031] The Reference Signal Receiving Power (RSRP) is one of the key parameters representing the wireless signal strength and the physical layer measurement requirements in the LTE network. It is the average value of the signal power received on all Resource Elements (REs) carrying reference signals within a certain symbol.

[0032] The electronic devices involved in the embodiments of this application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of User Equipment (UE), Mobile Station (MS), terminal devices, etc. For ease of description, the devices mentioned above are collectively referred to as electronic devices.

[0033] The original handover threshold involved in the existing algorithm was originally intended to truly reflect the actual total radiation power of the antenna (corresponding to the measured total radiation power) under the combined influence of communication characteristic parameters and external factors. However, since the reference signal receiving power corresponding to the first antenna or the second antenna has been corrected during factory production, specifically, the numerical difference in the first reference signal receiving power compensates for the differential influence caused by internal factors such as the conduction performance of the main board of the electronic device between the first antenna and the second antenna. That is, the first reference signal receiving power difference can only truly represent the difference in the antenna radiation performance caused by external factors such as human hand occlusion, resulting in the omission of the influence of communication characteristic parameters on the total radiation power in the actual calculation process of the existing algorithm.

[0034] In view of the above problems, the embodiments of this application provide an antenna handover method and related device. The following provides a detailed introduction to the embodiments of this application.

[0035] Please refer to Figure 1 , Figure 1 which is a schematic diagram of an electronic device provided by the embodiments of this application. The electronic device includes an application processor 120, a memory 130, a communication module 140, and one or more programs 131. The application processor 120 is connected to the memory 130 and the communication module 140 through an internal communication bus.

[0036] Among them, the one or more programs 131 are stored in the memory 130 and are configured to be executed by the application processor 120. The one or more programs 131 include instructions for executing any step in the following method embodiments.

[0037] Among them, the application processor 120 can be, for example, a Central Processing Unit (CPU), a general-purpose processor, a Digital Signal Processor (DSP), an Application-Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof. It can implement or execute various exemplary logic blocks, units, and circuits described in connection with the disclosure of this application. The processor can also be a combination that implements computing functions, such as a combination of one or more microprocessors, a combination of a DSP and a microprocessor, and so on. The communication unit can be the communication module 140, a transceiver, a transceiver circuit, etc., and the storage unit can be the memory 130.

[0038] The memory 130 can be a volatile memory or a non-volatile memory, or can include both volatile and non-volatile memories. Among them, the non-volatile memory can be a read-only memory (ROM), a programmable ROM (PROM), an erasable PROM (EPROM), an electrically erasable PROM (EEPROM), or a flash memory. The volatile memory can be a random access memory (RAM), which is used as an external cache. By way of example but not limitation, many forms of random access memory (RAM) are available, such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), synchlink DRAM (SLDRAM), and direct rambus RAM (DR RAM).

[0039] In a specific implementation, the application processor 120 is configured to execute any step performed by the electronic device in the following method embodiments.

[0040] It should be noted that the structural schematic diagram of the above electronic device is an example, and the specific devices included may be more or less, and there is no unique limitation here.

[0041] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of an antenna switching method provided by an embodiment of the present application. The antenna switching method described in this embodiment is applied to an electronic device as shown in Figure 1 . As shown in the figure, the antenna switching method includes the following operations.

[0042] Step 210: Obtain the first reference signal reception power of the first antenna in the target frequency band and the second reference signal reception power of the second antenna in the target frequency band. The first antenna and the second antenna are antennas among at least two antennas supported by the electronic device for mutual switching.

[0043] Specifically, the at least two antennas include the first antenna and the second antenna. It can be understood that the at least two antennas may also include other antennas, such as a third antenna and a fourth antenna. In the embodiment of the present application, the specific number of antennas is not limited here. In addition, in this embodiment, the first antenna and the second antenna are taken as examples for illustration. In other embodiments, the reference signal reception powers of two or more antennas to be switched among the at least two antennas may also be obtained to facilitate determining whether a switch is needed. For example, the reference signal reception power of the third antenna, the fourth antenna, and the fifth antenna are obtained to facilitate determining whether a switch is needed among the third antenna, the fourth antenna, and the fifth antenna.

[0044] Step 220: Determine the first reference signal reception power difference between the first reference signal reception power and the second reference signal reception power.

[0045] Specifically, the first reference signal reception power difference is the difference between the reference signal reception powers of the two antennas to be switched.

[0046] Step 230: If the difference in the received power of the first reference signal is greater than or equal to the target handover threshold corresponding to the first antenna, then switch the first antenna to the second antenna. The target handover threshold corresponding to the first antenna is a handover threshold value obtained by compensating the original handover threshold according to the difference between the second influence degree and the first influence degree. The first influence degree is the influence degree of the communication characteristic parameters of the first antenna on the total radiation power of the electronic device, and the second influence degree is the influence degree of the communication characteristic parameters of the second antenna on the total radiation power of the electronic device. The communication characteristic parameters include at least one of the following: conduction power, back-off power of specific absorption rate, and antenna efficiency. The antenna efficiency is used to characterize the antenna transceiver performance of the antenna in the target frequency band.

[0047] Specifically, the first antenna is the currently working antenna. In this example, the first antenna and the second antenna are taken as examples for illustration. It can be understood that it is also possible to determine whether to switch between two or more antennas according to actual requirements, and the specific number of antennas to be switched is not limited here. The target handover threshold corresponding to the first antenna is a handover threshold value obtained by compensating the original handover threshold according to the difference between the second influence degree and the first influence degree. The comparison result between the obtained target handover threshold corresponding to the first antenna and the difference in the received power of the first reference signal is used to determine whether to switch the first antenna to the second antenna. The first influence degree is the influence degree of the communication characteristic parameters of the first antenna on the total radiation power of the electronic device, and the second influence degree is the influence degree of the communication characteristic parameters of the second antenna on the total radiation power of the electronic device. The communication characteristic parameters include at least one of the following: conduction power, back-off power of specific absorption rate, and antenna efficiency. Affected by factors such as the conduction performance on the main board of the electronic device or the antenna efficiency between different antennas, there are differences between the first communication characteristic parameters of the first antenna and the second communication characteristic parameters of the second antenna, resulting in differences in the total radiation power when different antennas work. By compensating for the differences brought by these factors, the accuracy of the handover can be improved, and the overall performance of the electronic device after the antenna handover is better than the overall performance before the handover. That is, calculate the difference value of the communication characteristic parameters between the two antennas to be switched, obtain the difference value of the first influence degree and the second influence degree, and thus compensate it into the original handover threshold, so that the total radiation power of the electronic device after switching the antenna is greater than the total radiation power of the electronic device before the handover, so that the overall performance corresponding to switching to the first antenna is better than the overall performance before the handover.

[0048] It can be understood that the original handover threshold can be determined according to the switching benefit of actual requirements. For example, the original handover threshold can be any switching value between 2 dB and 5 dB, and the specific value is not limited here.

[0049] It can be seen that in this example, if the first antenna is switched to the second antenna, the target switching threshold corresponding to the first antenna is obtained, and the difference value between the communication characteristic parameters of the two antennas to be switched is compensated to the original switching threshold, thereby improving the switching accuracy. Based on the comparison result between the target switching threshold corresponding to the first antenna and the difference value of the received power of the first reference signal, it is determined whether to switch between the two antennas to be switched, making the switching determination more accurate and ensuring that the signal quality of the electronic device after switching the antenna is higher than that before switching, thereby improving the user experience.

[0050] In a possible example, the target switching threshold corresponding to the first antenna is determined through the following steps: determining the compensation value corresponding to the first antenna according to the communication characteristic parameters of the first antenna and the communication characteristic parameters of the second antenna, where the compensation value corresponding to the first antenna is used to represent the difference between the second influence degree and the first influence degree; determining the target switching threshold corresponding to the first antenna according to the original switching threshold and the compensation value corresponding to the first antenna.

[0051] In specific implementation, the total radiation power is affected by communication characteristic parameters and external factors. The target switching threshold corresponding to the first antenna is the switching threshold value obtained by compensating the original switching threshold according to the difference between the second influence degree and the first influence degree. The first influence degree is the influence degree of the communication characteristic parameters of the first antenna on the total radiation power of the electronic device, and the second influence degree is the influence degree of the communication characteristic parameters of the second antenna on the total radiation power of the electronic device. According to the difference between the communication characteristic parameters of the first antenna and the communication characteristic parameters of the second antenna, the original switching threshold is compensated to obtain the target switching threshold corresponding to the first antenna. Since the communication characteristic parameters include at least one of the following: conduction power, back-off power of specific absorption rate, and antenna efficiency, the parameters included in the communication characteristic parameters can be determined according to actual needs. For example, the communication characteristic parameters include conduction power, back-off power of specific absorption rate, and antenna efficiency, or the communication characteristic parameters include conduction power and antenna efficiency. The specific types of parameters included are not limited here.

[0052] It can be seen that in this example, by compensating for the difference between the first communication characteristic parameter of the first antenna and the second communication characteristic parameter of the second antenna, the differences caused by factors such as conduction efficiency during the operation of different antennas are compensated, thereby improving the accuracy of switching.

[0053] In a possible example, when the communication characteristic parameters include conduction power, back-off power of specific absorption rate, and the antenna efficiency corresponding to the target frequency band, the determining the compensation value corresponding to the first antenna according to the communication characteristic parameters of the first antenna and the communication characteristic parameters of the second antenna includes: calculating the compensation value corresponding to the first antenna through the following formula:

[0054] P i +( - S i ) + TE i - P j -( - S j ) - TE j = Δ ij ;

[0055] Wherein, the P i is the conduction power of the first antenna, the - S i is the back - off power of the specific absorption rate of the first antenna, the TE i is the antenna efficiency of the first antenna, the P j is the conduction power of the second antenna, the - S j is the back - off power of the specific absorption rate of the second antenna, the TE j is the antenna efficiency of the second antenna, and the Δ ij is the compensation value corresponding to the first antenna when the first antenna is switched to the second antenna.

[0056] In specific implementation, when determining whether to switch the first antenna to the second antenna, the compensation value corresponding to the first antenna is obtained. The communication characteristic parameters of the first antenna include the conduction power of the first antenna, the back - off power of the specific absorption rate of the first antenna, and the antenna efficiency of the first antenna. The communication characteristic parameters of the second antenna include the conduction power of the second antenna, the back - off power of the specific absorption rate of the second antenna, and the antenna efficiency of the second antenna. Among them, the calculation order between the communication characteristic parameters of the first antenna and the communication characteristic parameters of the second antenna can be determined according to actual needs, and specific limitations are not made here. For example: adding the conduction power of the first antenna to the back - off power of the specific absorption rate of the first antenna to obtain a first value, and obtaining a first added value by adding this first value to the antenna efficiency of the first antenna; adding the conduction power of the second antenna to the back - off power of the specific absorption rate of the second antenna to obtain a second value, and obtaining a second added value by adding this second value to the antenna efficiency of the second antenna. The compensation value corresponding to the first antenna is the difference between this first added value and this second added value. The specific calculation formula for the compensation value corresponding to the first antenna is as follows:

[0057] [P i +( - S i ) + TE i -[P j +( - S j ) + TE j = Δ ij ;

[0058] Therefore, P i +( - S i ) + TE i - Pj -(-S j )-TE j = Δ ij ;

[0059] Therefore, (P i -S i +TE i ) - (P j -S j +TE j ) = Δ ij ;

[0060] Wherein, P i is the conduction power of the first antenna, S i is the absolute value of the back-off power of the specific absorption rate of the first antenna. Therefore, the back-off power of the specific absorption rate of the first antenna is -S i , TE i is the antenna efficiency of the first antenna, P j is the conduction power of the second antenna, S j is the absolute value of the back-off power of the specific absorption rate of the second antenna. Therefore, -S j is the back-off power of the specific absorption rate of the second antenna, TE j is the antenna efficiency of the second antenna, Δ ij is the compensation value corresponding to the first antenna. Alternatively, the conduction power difference is obtained by subtracting the conduction power of the second antenna from the conduction power of the first antenna; the back-off power difference is obtained by subtracting the back-off power of the specific absorption rate of the second antenna from the back-off power of the specific absorption rate of the first antenna; the antenna efficiency difference is obtained by subtracting the antenna efficiency of the second antenna from the antenna efficiency of the first antenna. The compensation value corresponding to the first antenna is the sum of the conduction power difference, the back-off power difference, and the antenna efficiency difference. The compensation value corresponding to the first antenna is calculated by the following formula:

[0061] (P i -P j ) + [(-S i ) - (-S j )] + (TE i -TE j ) = Δ ij .

[0062] It can be seen that in this example, by compensating for the differences between the first communication characteristic parameters of the first antenna and the second communication characteristic parameters of the second antenna, the differences between the total radiation powers during the operation of the antennas are compensated, thereby improving the accuracy of handover.

[0063] Wherein, there is a corresponding relationship between the antenna currently used by the electronic device and the compensation value. The following two cases are specifically described:

[0064] (1) When the antenna currently used by the electronic device is the first antenna, the existing algorithm process is as follows:

[0065] The difference between the reference signal received power RSRP2 of the second antenna and the reference signal received power RSRP1 of the first antenna is calculated, and the magnitude relationship between this difference and the original threshold is compared. The improved algorithm is as follows: After compensating for the influence of communication characteristic parameters on the total radiation power, calculate the value of (RSRP2 - RSRP1) + [P2 + (-S2) + TE2 - P1 - (-S1) - TE1], and compare the magnitude relationship between this value and the original threshold, where [P2 + (-S2) + TE2] is used to represent the second influence degree, and [P1 + (-S1) + TE1] is used to represent the first influence degree. Therefore, when the antenna currently used by the electronic device is the first antenna, the corresponding compensation value (i.e., moving the newly added part on the left side of the improved algorithm comparison formula to the right side of the comparison formula) is -[P2 + (-S2) + TE2 - P1 - (-S1) - TE1], that is, P1 + (-S1) + TE1 - P2 - (-S2) - TE2.

[0066] (2) When the antenna currently used by the electronic device is the second antenna, the existing algorithm process is as follows:

[0067] The difference between the reference signal received power RSRP1 of the first antenna and the reference signal received power RSRP2 of the second antenna is calculated, and the magnitude relationship between this difference and the original threshold is compared. The improved algorithm is as follows: After compensating for the influence of communication characteristic parameters on the total radiation power, calculate the value of (RSRP1 - RSRP2) + [P1 + (-S1) + TE1 - P2 - (-S2) - TE2], and compare the magnitude relationship between this value and the original threshold, where [P2 + (-S2) + TE2] is used to represent the second influence degree, and [P1 + (-S1) + TE1] is used to represent the first influence degree. Therefore, when the antenna currently used by the electronic device is the second antenna, the corresponding compensation value (i.e., moving the newly added part on the left side of the improved algorithm comparison formula to the right side of the comparison formula) is -[P1 + (-S1) + TE1 - P2 - (-S2) - TE2], that is, P2 + (-S2) + TE2 - P1 - (-S1) - TE1.

[0068] In a possible example, determining the target switching threshold corresponding to the first antenna according to the original switching threshold and the compensation value corresponding to the first antenna includes: obtaining the sum of the original switching threshold and the compensation value corresponding to the first antenna, and this sum is the target switching threshold corresponding to the first antenna.

[0069] In specific implementation, the target switching threshold corresponding to the first antenna is the sum of the compensation value corresponding to the first antenna and the original switching threshold.

[0070] It can be seen that in this example, the original handover threshold is compensated by the compensation value corresponding to the first antenna to obtain the target handover threshold corresponding to the first antenna. By comparing with the target handover threshold corresponding to the first antenna, it is determined whether to switch the antenna, improving the accuracy of antenna handover.

[0071] In one possible example, the determining the difference in the first reference signal received power between the first reference signal received power and the second reference signal received power includes: obtaining the difference obtained by subtracting the first reference signal received power from the second reference signal received power, and the difference is the difference in the first reference signal received power.

[0072] In a specific implementation, when determining whether to switch the first antenna to the second antenna, compare the size of the target handover threshold corresponding to the first antenna with the difference in the first reference signal received power. If the difference in the first reference signal received power is greater than or equal to the target handover threshold corresponding to the first antenna, then switch the first antenna to the second antenna. The specific comparison formula is:

[0073] RSRP j -RSRP i ≥Δ ij +G;

[0074] Wherein, this RSRP i is the first reference signal received power, RSRP j is the second reference signal received power, Δ ij is the compensation value corresponding to the first antenna, and G is the preset original handover threshold.

[0075] It can be seen that in this example, the target handover threshold corresponding to the first antenna is determined according to the difference in the communication characteristic parameters between the first antenna and the second antenna and the original handover threshold. Through the comparison result of the target handover threshold corresponding to the first antenna and the difference in the first reference signal received power, it is determined whether to switch between the two antennas to be switched, preventing the total radiation power of the antenna after switching from being lower than the total radiation power of the antenna before switching, improving the communication quality after switching, making the accuracy of handover judgment higher, and thus improving the user experience.

[0076] For example, please refer to Table 1. Table 1 is a data comparison table between the first antenna and the second antenna when determining whether to switch the first antenna to the second antenna. Taking the target frequency band as the LTE B41 frequency band as an example, the specific data is shown in Table 1 below.

[0078]

[0079]

[0080] In a specific implementation, the electronic device determines the magnitude relationship between the target switching threshold corresponding to the first antenna and the second antenna and the difference in the first reference signal reception power. As shown in Table 1, the conduction power of the first antenna is 23 dBm, the antenna efficiency of the first antenna is -7 dBm, the back-off power of the specific absorption rate of the first antenna is -1 dBm, the conduction power of the second antenna is 20 dBm, the antenna efficiency of the second antenna is -7 dBm, and the back-off power of the specific absorption rate corresponding to the second antenna is -1 dBm. Substitute the communication characteristic parameters of the first antenna and the communication characteristic parameters of the second antenna into the formula: P i +(-S i )+TE i -P j -(-S j )-TE j =Δ ij ; The compensation value corresponding to the first antenna is obtained as 3 dB. If the preset original switching threshold is 2 dB, since the target switching threshold corresponding to the first antenna is the sum of the compensation value corresponding to the first antenna and the original switching threshold, the target switching threshold corresponding to the first antenna is 5 dB. When the first reference signal reception power drops from -100 dBm to -105 dBm, at this time, the second reference signal reception power is -100 dBm. Subtract the first reference signal reception power from the second reference signal reception power to obtain the first reference signal reception power difference of 5 dB. The first reference signal reception power difference is equal to the target switching threshold corresponding to the first antenna, so the first antenna can be switched to the second antenna. Referring to Table 1, according to actual measurement, the total radiation power of the electronic device corresponding to the first antenna is 11 dBm, and the total radiation power of the electronic device corresponding to the second antenna is 13 dBm. Therefore, the total radiation power corresponding to the second antenna after switching is greater than the total radiation power corresponding to the first antenna.

[0081] It can be seen that in this example, by compensating for the differential effects brought by factors such as the conduction difference between the first antenna and the second antenna on the main board, the target switching threshold corresponding to the first antenna is obtained. Based on the comparison result between the target switching threshold corresponding to the first antenna and the first reference signal reception power difference, it is determined whether to switch between the two antennas, preventing the total radiation power of the electronic device after switching from being lower than the total radiation power before switching the antenna, improving the accuracy of switching, and thus improving the user experience.

[0082] In a possible example, after switching the first antenna to the second antenna, the method further includes: obtaining a difference between the first reference signal receiving power and the second reference signal receiving power, where the difference is the second reference signal receiving power difference; if the second reference signal receiving power difference is greater than or equal to a target switching threshold corresponding to the second antenna, switching the second antenna to the first antenna, where the target switching threshold corresponding to the second antenna is a switching threshold value obtained by compensating the original switching threshold according to the difference between the first influence degree and the second influence degree.

[0083] In a specific implementation, if it is necessary to determine whether to switch the second antenna to the first antenna, it can be determined whether to switch according to the magnitude relationship between the target switching threshold corresponding to the second antenna and the second reference signal receiving power difference. Obtain the first reference signal receiving power of the first antenna and the second reference signal receiving power of the second antenna, subtract the second reference signal receiving power from the first reference signal receiving power to obtain the second reference signal receiving power difference, obtain the target switching threshold corresponding to the second antenna according to the compensation value corresponding to the second antenna and the original switching threshold, compare the magnitude of the target switching threshold corresponding to the second antenna and the second reference signal receiving power difference, and if the second reference signal receiving power difference is greater than or equal to the target switching threshold corresponding to the second antenna, switch the second antenna to the first antenna.

[0084] In a possible example, the second reference signal receiving power difference can also be calculated from the first reference signal receiving power corresponding to the first antenna and the second reference signal receiving power corresponding to the second antenna after being changed according to the actual situation, and it is determined whether to switch according to real-time data, so as to improve the accuracy of switching.

[0085] In a possible example, when the communication characteristic parameters include the conduction power, the back-off power of the specific absorption rate, and the antenna efficiency corresponding to the target frequency band, the target switching threshold corresponding to the second antenna is determined through the following steps: calculating the compensation value corresponding to the second antenna through the following formula:

[0086] P j +(-S j )+TE j -P i -(-S i )-TE i =Δ ji ;

[0087] Wherein, the Δ jiWhen the second antenna is switched to the first antenna, the compensation value corresponding to the second antenna, which is used to characterize the difference between the first influence degree and the second influence degree; determine the target switching threshold corresponding to the second antenna according to the original switching threshold and the compensation value corresponding to the second antenna.

[0088] In a specific implementation, the specific calculation formula for the compensation value corresponding to the second antenna is as follows:

[0089] [P j +(-S j )+TE j -[P i +(-S i )+TE i =Δ ji ;

[0090] Therefore, P j +(-S j )+TE j -P i -(-S i )-TE i -=Δ ji ;

[0091] Therefore, (P j -S j +TE j )-(P i -S i +TE i )=Δ ji ;

[0092] Compare the size of the target switching threshold corresponding to the second antenna and the difference in the second reference signal receiving power. If the difference in the second reference signal receiving power is greater than or equal to the target switching threshold corresponding to the second antenna, then switch the second antenna to the first antenna. The specific comparison formula is:

[0093] RSRP i- RSRP j ≥Δ ji +G;

[0094] Among them, this RSRP i is the first reference signal receiving power, RSRP j is the second reference signal receiving power, Δ ji is the compensation value corresponding to the second antenna, and G is the preset original switching threshold.

[0095] It can be seen that in this example, the original handover threshold is compensated to obtain the target handover threshold corresponding to the second antenna. By comparing the difference between the target handover threshold corresponding to the second antenna and the second reference signal reception power, it is determined whether to switch the antenna, improving the communication quality after handover and making the handover judgment more accurate.

[0096] For example, if it is determined whether to switch the second antenna to the first antenna, it is necessary to judge the magnitude of the difference between the target handover threshold corresponding to the second antenna and the second reference signal reception power. The specific judgment process for determining whether to switch the second antenna to the first antenna includes: obtaining the first reference signal reception power of the first antenna and the second reference signal reception power of the second antenna, subtracting the second reference signal reception power from the first reference signal reception power to obtain the first reference signal reception power difference, comparing the magnitude of the target handover threshold corresponding to the second antenna and the second reference signal reception power difference. If the second reference signal reception power difference is greater than the target handover threshold corresponding to the second antenna, then the second antenna is re-switched to the first antenna. For example, please refer to Table 2, which is a data comparison table of the first antenna and the second antenna when determining whether to switch the second antenna to the first antenna.

[0097] Table 2

[0098]

[0099] As shown in Table 2, the conduction power of the first antenna is 23 dBm, the antenna efficiency of the first antenna is -7 dBm, the back-off power of the specific absorption rate of the first antenna is -1 dBm, the conduction power of the second antenna is 20 dBm, the antenna efficiency of the second antenna is -7 dBm, and the back-off power of the specific absorption rate of the second antenna is -1 dBm. Substitute the communication characteristic parameters of the first antenna and the communication characteristic parameters of the first antenna into the formula: P j -S j +TE j -P i +S i -TE i =Δ ji, the compensation value corresponding to the second antenna is -3 dB. If the preset original switching threshold is 2 dB, since the target switching threshold corresponding to the second antenna is the sum of the compensation value corresponding to the second antenna and the original switching threshold, the target switching threshold corresponding to the second antenna is -1 dB. When the second reference signal reception power decreases from -100 dBm to -104 dBm and the first reference signal reception power is -105 dBm, subtracting the second reference signal reception power from the first reference signal reception power gives a second reference signal reception power difference of -1 dB. Comparing the magnitude of the second reference signal reception power difference with the target switching threshold, the second reference signal reception power difference is equal to the target switching threshold corresponding to the second antenna, and it is determined that the second antenna can be switched to the first antenna. Since the total radiation power of the second antenna obtained by actual measurement is 9 dBm and the total radiation power of the first antenna is 11 dBm, the total radiation power of the first antenna is greater than that of the second antenna, and the total radiation power of the electronic device is higher after switching to the first antenna, so the performance of the electronic device after switching is better.

[0100] It can be seen that in this example, for different antennas, different target switching thresholds can be determined according to the conduction power, antenna efficiency, and back-off power of specific absorption rate of different antennas, avoiding the influence brought by factors such as different conduction performances of different antennas on the motherboard and improving the accuracy of antenna switching.

[0101] It can be understood that the target frequency band can also be other frequency bands, such as LTE B40 and LTE B39, and specific details are not limited here.

[0102] In a possible example, when the communication characteristic parameter includes the conduction power and the back-off power of specific absorption rate, determining the compensation value corresponding to the first antenna according to the communication characteristic parameters of the first antenna and the second antenna includes: calculating the compensation value corresponding to the first antenna through the following formula:

[0103] P i +(-S i )-P j -(-S j )=Δ ij ;

[0104] where, P i is the conduction power of the first antenna, -S i is the back-off power of specific absorption rate of the first antenna, P j is the conduction power of the second antenna, -S j is the back-off power of specific absorption rate of the second antenna, and Δ ij is the compensation value corresponding to the first antenna.

[0105] In a specific implementation, if the communication characteristic parameter includes the conduction power and the back-off power of the specific absorption rate, in the target frequency band, the communication characteristic parameter of the first antenna includes the conduction power of the first antenna and the back-off power of the specific absorption rate of the first antenna, and the communication characteristic parameter of the second antenna includes the conduction power of the second antenna and the back-off power of the specific absorption rate of the second antenna. Among them, the calculation order between the communication characteristic parameter of the first antenna and the communication characteristic parameter of the second antenna can be determined according to actual needs, and specific restrictions are not imposed here. For example, the compensation value corresponding to the first antenna is calculated through the following formula:

[0106] [P i +(-S i )]-[P j +(-S j )]=Δ ij ;

[0107] Therefore, (P i -S i )-(P j -S j )=Δ ij ;

[0108] Or (P i -P j )+[(-S i )-(-S j )]=Δ ij ;

[0109] Among them, the target handover threshold corresponding to the first antenna is the sum of the compensation value corresponding to the first antenna and the original handover threshold. The specific judgment process for determining whether to switch the first antenna to the second antenna includes: obtaining the first reference signal receiving power of the first antenna and the second reference signal receiving power of the second antenna, calculating the difference between the second reference signal receiving power and the first reference signal receiving power, and this difference is the first reference signal receiving power difference. Compare the size of the target handover threshold corresponding to the first antenna and the first reference signal receiving power difference. If the first reference signal receiving power difference is greater than or equal to the target handover threshold corresponding to the first antenna, then switch the first antenna to the second antenna. The specific comparison formula is:

[0110] RSRP j -RSRP i ≥Δ ij +G。

[0111] It can be seen that in this example, the compensation value corresponding to the first antenna is determined according to the difference between the communication characteristic parameters of the first antenna and those of the second antenna, so as to compensate for the differences caused by factors such as the conduction difference between the first antenna and the second antenna on the main board, obtain the target switching threshold corresponding to the first antenna, and determine whether to switch between the two antennas to be switched based on the comparison result between the target switching threshold corresponding to the first antenna and the difference in the first reference signal receiving power, preventing the total radiation power after switching from being lower than the total radiation power of the electronic device before switching, improving the accuracy of switching, and thus improving the user experience.

[0112] In a possible example, when the communication characteristic parameters include the conduction power and the antenna efficiency corresponding to the target frequency band, determining the compensation value corresponding to the first antenna according to the communication characteristic parameters of the first antenna and those of the second antenna includes: calculating the compensation value corresponding to the first antenna through the following formula:

[0113] P i +TE i -P j -TE j =Δ ij ;

[0114] Wherein, P i is the conduction power of the first antenna, TE i is the antenna efficiency of the first antenna, P j is the conduction power of the second antenna, TE j is the antenna efficiency of the second antenna, and Δ ij is the compensation value corresponding to the first antenna.

[0115] In specific implementation, if the communication characteristic parameters include the conduction power and the back-off power of the specific absorption rate, at the target frequency band, the communication characteristic parameters of the first antenna include the conduction power of the first antenna and the antenna efficiency of the first antenna, and the communication characteristic parameters of the second antenna include the conduction power of the second antenna and the antenna efficiency of the second antenna. Among them, the calculation order between the communication characteristic parameters of the first antenna and those of the second antenna can be determined according to actual requirements, and specific limitations are not made here. For example, the compensation value corresponding to the first antenna is calculated through the following formula:

[0116] (P i +TE i )-(P j +TE j )=Δ ij ;

[0117] Or (P i -P j )+(TE i -TE j )=Δij ;

[0118] It can be seen that in this example, the compensation value corresponding to the first antenna is determined according to the difference between the communication characteristic parameters of the first antenna and the communication characteristic parameters of the second antenna, so as to compensate for the differences caused by factors such as conduction differences between the first antenna and the second antenna on the main board, obtain the target switching threshold corresponding to the first antenna, improve the accuracy of switching, and thus improve the user experience.

[0119] In a possible example, when the communication characteristic parameters include the back-off power of the specific absorption rate and the antenna efficiency corresponding to the target frequency band, determining the compensation value corresponding to the first antenna according to the communication characteristic parameters of the first antenna and the communication characteristic parameters of the second antenna includes: calculating the compensation value corresponding to the first antenna through the following formula:

[0120] -S i +TE i -(-S j )-TE j =Δ ij ;

[0121] Where, -S i is the back-off power of the specific absorption rate of the first antenna, TE i is the antenna efficiency of the first antenna, -S j is the back-off power of the specific absorption rate of the second antenna, TE j is the antenna efficiency of the second antenna, Δ ij is the compensation value corresponding to the first antenna.

[0122] In specific implementation, in the target frequency band, if it is necessary to switch the first antenna to the second antenna, when the communication characteristic parameters include the back-off power of the specific absorption rate and the antenna efficiency corresponding to the target frequency band, the communication characteristic parameters of the first antenna include the back-off power of the specific absorption rate of the first antenna and the antenna efficiency of the first antenna corresponding to the target frequency band, and the communication characteristic parameters of the second antenna include the back-off power of the specific absorption rate of the second antenna and the antenna efficiency of the second antenna corresponding to the target frequency band. Among them, the calculation order between the communication characteristic parameters of the first antenna and the communication characteristic parameters of the second antenna can be determined according to actual needs, and specific restrictions are not made here. For example, the compensation value corresponding to the first antenna is calculated through the following formula:

[0123] (-S i +TE i )-(-S j +TE j )=Δ ij ;

[0124] Or [(-S i )-(-S j )]+(TEi -TE j ) = Δ ij ;

[0125] Among them, the target handover threshold corresponding to the first antenna is the sum of the compensation value corresponding to the first antenna and the original handover threshold. The specific judgment process for determining whether to switch the first antenna to the second antenna includes: obtaining the first reference signal receiving power of the first antenna and the second reference signal receiving power of the second antenna, determining the difference in the first reference signal receiving power based on the first reference signal receiving power and the second reference signal receiving power, comparing the size of the target handover threshold corresponding to the first antenna with the difference in the first reference signal receiving power. If the difference in the first reference signal receiving power is greater than or equal to the target handover threshold corresponding to the first antenna, then switch the first antenna to the second antenna. The specific comparison formula is:

[0126] RSRP j -RSRP i ≥Δ ij +G;

[0127] It can be seen that in this example, the differences between the communication characteristic parameters of different antennas are compensated. Based on the comparison result between the target handover threshold corresponding to the first antenna and the difference in the first reference signal receiving power, it is determined whether to switch the antenna, preventing the total radiation power of the electronic device after the handover from being lower than the total radiation power of the electronic device before the handover, improving the accuracy of the handover, and thus improving the user experience.

[0128] In a possible example, when the communication characteristic parameter includes the conduction power, the communication characteristic parameter of the first antenna includes the conduction power of the first antenna, and the communication characteristic parameter of the second antenna includes the conduction power of the second antenna. Therefore, the compensation value corresponding to the first antenna is determined based on the difference between the conduction power of the first antenna and the conduction power of the second antenna. The sum of the compensation value corresponding to the first antenna and the original handover threshold is the target handover threshold corresponding to the first antenna. The specific judgment process for determining whether to switch the first antenna to the second antenna includes: obtaining the first reference signal receiving power of the first antenna and the second reference signal receiving power of the second antenna, determining the difference in the first reference signal receiving power based on the first reference signal receiving power and the second reference signal receiving power, comparing the size of the target handover threshold corresponding to the first antenna with the difference in the first reference signal receiving power. If the difference in the first reference signal receiving power is greater than or equal to the target handover threshold corresponding to the first antenna, then switch the first antenna to the second antenna. The specific calculation formula is:

[0129] P i -P j = Δ ij ;

[0130] RSRP j -RSRPi ≥Δ ij +G;

[0131] Wherein, Pi is the conduction power of the first antenna, and P j is the conduction power of the second antenna, and this RSRP i is the first reference signal received power, and RSRP j is the second reference signal received power, and Δ ij is the compensation value corresponding to the first antenna when the communication characteristic parameter includes the conduction power, and G is a preset original handover threshold.

[0132] It can be seen that in this example, by comparing the result of the difference between the target handover threshold corresponding to the first antenna and the first reference signal received power, it is determined whether to switch the antenna, preventing the total radiation power of the antenna after handover from being lower than the total radiation power of the antenna before handover, improving the accuracy of handover, and thus improving the user experience. Among them, the target handover threshold is determined according to the conduction power of the first antenna, the conduction power of the second antenna, and the original handover threshold. By compensating for the conduction difference between the first antenna and the second antenna, it is prevented that after the antenna is switched according to the original handover threshold, due to the influence of the conduction performance, the performance of the electronic device after handover is lower than that before handover, reducing the user experience.

[0133] In a possible example, when the communication characteristic parameter includes the back-off power of the specific absorption rate, the communication characteristic parameter of the first antenna includes the back-off power of the specific absorption rate of the first antenna, and the communication characteristic parameter of the second antenna includes the back-off power of the specific absorption rate of the second antenna. The compensation value corresponding to the first antenna is determined according to the back-off power of the specific absorption rate of the first antenna and the back-off power of the specific absorption rate corresponding to the second antenna. The sum of the compensation value corresponding to the first antenna and the original handover threshold is the target handover threshold corresponding to the first antenna. Compare the magnitude of the difference between the target handover threshold corresponding to the first antenna and the first reference signal received power. If the difference of the first reference signal received power is greater than or equal to the target handover threshold corresponding to the first antenna, then switch the first antenna to the second antenna. The specific calculation formula is:

[0134] -S i -(-S j ) = Δ ij ;

[0135] RSRP j -RSRP i ≥Δ ij +G;

[0136] Wherein, -S i is the back-off power of the specific absorption rate of the first antenna, -S j is the back-off power of the specific absorption rate of the second antenna, and this RSRP iis the received signal strength of the first reference signal, RSRP j is the received signal strength of the second reference signal, Δ ij When it is the fallback power of the communication characteristic parameter including the specific absorption rate, the compensation value corresponding to the first antenna, and G is the preset original handover threshold.

[0137] It can be seen that in this example, by comparing the result of the difference between the target handover threshold corresponding to the first antenna and the received signal strength of the first reference signal, it is determined whether to switch the antenna, preventing the total radiation power of the electronic device after the antenna switch from being lower than the total radiation power before the switch, improving the accuracy of the handover judgment, and thus improving the user experience.

[0138] In a possible example, when the communication characteristic parameter includes the antenna efficiency corresponding to the target frequency band, the communication characteristic parameter of the first antenna includes the antenna efficiency of the first antenna, and the communication characteristic parameter of the second antenna includes the antenna efficiency of the second antenna. Therefore, the compensation value of the first antenna is determined according to the antenna efficiency of the first antenna and the antenna efficiency of the second antenna. The sum of the compensation value corresponding to the first antenna and the original handover threshold is the target handover threshold corresponding to the first antenna. The received signal strength of the first reference signal of the first antenna and the received signal strength of the second reference signal of the second antenna are obtained, and the difference in the received signal strength of the first reference signal is calculated. The size of the difference in the received signal strength of the first reference signal and the target handover threshold corresponding to the first antenna is compared. If the difference in the received signal strength of the first reference signal is greater than or equal to the target handover threshold corresponding to the first antenna, the first antenna is switched to the second antenna. The specific calculation formula is:

[0139] TE i -TE j =Δ ij ;

[0140] RSRP j -RSRP i ≥Δ ij +G;

[0141] Wherein, TE i is the antenna efficiency of the first antenna, TE j is the antenna efficiency of the second antenna, and this RSRP i is the received signal strength of the first reference signal, RSRP j is the received signal strength of the second reference signal, Δ ij is the compensation value corresponding to the first antenna when the communication characteristic parameter includes the antenna efficiency, and G is the preset original handover threshold.

[0142] It can be seen that in this example, the target switching threshold corresponding to the first antenna is determined according to the antenna efficiency of the first antenna, the antenna efficiency of the second antenna, and the original switching threshold. By comparing the obtained difference in the received power of the first reference signal with the target switching threshold corresponding to the first antenna, it is determined whether to switch the antenna, preventing the total radiation power of the antenna after switching from being lower than that of the antenna before switching, improving the accuracy of switching, and thus improving the user experience.

[0143] It can be understood that the steps of obtaining the target switching threshold corresponding to the first antenna and the target switching threshold corresponding to the second antenna can be executed on the electronic device and obtained through the electronic device; the target switching threshold corresponding to the first antenna and the target switching threshold corresponding to the second antenna can also be executed on other devices with transmission functions and transmitted to the electronic device, enabling the electronic device to perform the determination process with the difference in the received power of the first reference signal and decide whether to switch the antenna. The execution device of the steps of obtaining the target switching threshold corresponding to the first antenna and the target switching threshold corresponding to the second antenna is not limited here.

[0144] An embodiment of the present application provides an antenna switching device, and this determination device can be an electronic device. Specifically, the antenna switching device is used to execute the steps performed by the electronic device in the above antenna switching method. The antenna switching device provided by the embodiment of the present application may include modules corresponding to the respective steps.

[0145] The embodiment of the present application can divide the positioning display control device into functional modules according to the above method example. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of a software functional module. The division of modules in the embodiment of the present application is illustrative, only a logical function division, and there can be other division methods in actual implementation.

[0149] A switching unit 330, configured to switch the first antenna to the second antenna. The target switching threshold corresponding to the first antenna is a switching threshold value obtained by compensating the original switching threshold according to the difference between the second influence degree and the first influence degree. The first influence degree is the influence degree of the communication characteristic parameter of the first antenna on the total radiation power of the electronic device, and the second influence degree is the influence degree of the communication characteristic parameter of the second antenna on the total radiation power of the electronic device. The communication characteristic parameter includes at least one of the following: conduction power, back-off power of specific absorption rate, and antenna efficiency, where the antenna efficiency is used to characterize the antenna transceiver performance of the antenna in the target frequency band.

[0150] In a possible example, the target switching threshold corresponding to the first antenna is determined through the following steps: determining a compensation value corresponding to the first antenna according to the communication characteristic parameter of the first antenna and the communication characteristic parameter of the second antenna, where the compensation value corresponding to the first antenna is used to characterize the difference between the second influence degree and the first influence degree; and determining the target switching threshold corresponding to the first antenna according to the original switching threshold and the compensation value corresponding to the first antenna.

[0152] P i +(-S i )+TE i -P j -(-S j )-TE j =Δ ij ;

[0153] where, the P i is the conduction power of the first antenna, the -S i is the back-off power of specific absorption rate of the first antenna, the TE i is the antenna efficiency of the first antenna, the P j is the conduction power of the second antenna, the -S j is the back-off power of specific absorption rate of the second antenna, the TE j is the antenna efficiency of the second antenna, and the Δ ij is the compensation value corresponding to the first antenna when the first antenna is switched to the second antenna.

[0154] In a possible example, determining the target handover threshold corresponding to the first antenna according to the compensation value corresponding to the first antenna and the original handover threshold includes: obtaining the sum of the original handover threshold and the compensation value corresponding to the first antenna, and the sum is the target handover threshold corresponding to the first antenna.

[0155] In a possible example, the determining unit 320 is further configured to obtain the difference between the second reference signal reception power and the first reference signal reception power, and the difference is the first reference signal reception power difference.

[0156] In a possible example, after switching the first antenna to the second antenna, it further includes: obtaining the difference between the first reference signal reception power and the second reference signal reception power, and the difference is the second reference signal reception power difference; if the second reference signal reception power difference is greater than or equal to the target handover threshold corresponding to the second antenna, switching the second antenna to the first antenna, and the target handover threshold corresponding to the second antenna is the handover threshold value obtained by compensating the original handover threshold according to the difference between the first influence degree and the second influence degree.

[0157] In a possible example, when the communication characteristic parameters include the conduction power, the back-off power of the specific absorption rate, and the antenna efficiency corresponding to the target frequency band, the target handover threshold corresponding to the second antenna is determined through the following steps: calculating the compensation value corresponding to the second antenna through the following formula:

[0158] P j +(-S j )+TE j -P i -(-S i )-TE i =Δ ji ;

[0159] wherein, the Δ ji is the compensation value corresponding to the second antenna when the second antenna is switched to the first antenna, and the compensation value corresponding to the second antenna is used to characterize the difference between the first influence degree and the second influence degree; and determining the target handover threshold corresponding to the second antenna according to the original handover threshold and the compensation value corresponding to the second antenna.
