[0020] See figure 1 , figure 1 It is a schematic flowchart of an embodiment of an antenna switching method for a mobile terminal of the present invention. The invention can realize the switching between antennas in the mobile terminal to allocate antennas with different performances and select the antenna with the best performance as the main antenna. In the mobile terminal, the main antenna is used for transmitting and receiving signals, and the diversity antenna is used for receiving signals. The antennas in the mobile terminal applied in the antenna switching method of this embodiment constitute an antenna group, and the antenna group includes at least three antennas. The antenna switching method of this embodiment includes the following steps.

[0021] S101: Acquire status information of the mobile terminal.

[0022] The state information of the mobile terminal acquired in this step S101 may be about the environment where the mobile terminal is currently located, or may be about the current usage of the mobile terminal. Since the performance of the antenna in the mobile terminal is related to the status information of the mobile terminal, it is necessary to determine the quality of the antenna performance in the current state according to the status information.

[0023] This step S101 may be to obtain the frequency band information of the environment where the mobile terminal is located. If the frequency band information is a high frequency band, that is, when the mobile terminal is in a high frequency band cell, the performance of the high frequency antenna lower frequency band antenna is better; correspondingly, if the frequency band information is low frequency band , The performance of the low-frequency antenna and the higher-frequency antenna is better.

[0024] This step S101 may also be to obtain user operation information of the mobile terminal. For example, when an antenna exists in a part where the user holds the mobile terminal, the performance of the antenna in this part is worse than that in other parts.

[0025] The state information of the mobile terminal can be acquired by automatic sensing such as the mobile terminal's own sensors, or it can be acquired through autonomous input by the user.

[0026] S102: Select two antennas from the antenna group according to the status information.

[0027] As can be seen from the above description of step S101, according to the acquired state information, the performance of the antenna in the current state can be known. Therefore, in this step S102, two antennas with better performance are selected from the antenna group according to the state information.

[0028] If the antenna group of the mobile terminal includes a full-frequency antenna, a high-frequency antenna, and a low-frequency antenna, the frequency band information of the environment where the mobile terminal is located is acquired in step S101, the two antennas selected in this step S102 are full-frequency antennas, and according to High-frequency antenna or low-frequency antenna selected by frequency band information.

[0029] The above step S101 can also obtain user operation information of the mobile terminal. In this step S102, the degree to which the antenna in the antenna group is affected by the user operation can be determined according to the user operation information, and then the two antenna groups that are least affected by the user operation are selected from the antenna group antenna.

[0030] For example, for the case where the first antenna included in the antenna group is set at the top of the mobile terminal, the second antenna is set at the bottom left of the mobile terminal, and the third antenna is set at the bottom right of the mobile terminal, the user operation information obtained in step S101 Can hold information for users.

[0031] When the user's holding information is left-hand holding, it is considered that the left-hand holding has the greatest impact on the performance of the second antenna at the bottom left of the mobile terminal. Therefore, the first antenna and the third antenna are selected in step S102; when the user holding information is When holding with the right hand, holding with the right hand has the greatest impact on the performance of the third antenna at the bottom right of the mobile terminal, so the first antenna and the second antenna are selected in step S102.

[0032] S103: Use the two selected antennas as the main antenna and the diversity antenna respectively.

[0033] The two antennas selected in step S102 are respectively used as the main antenna and the diversity antenna. In this step, the selection of the main antenna and the diversity antenna can be randomly allocated or allocated according to the default priority, that is, the antenna with a higher priority is preferentially selected as the main antenna.

[0034] S104: Compare the performance of the current main antenna and the current diversity antenna.

[0035] After initially determining the main antenna and diversity antenna in step S103, compare the performance of the current main antenna and the current diversity antenna, and evaluate the performance of the current main antenna and diversity antenna to ensure that the antenna with the best performance is used as the main antenna antenna.

[0036] If the comparison result in this step S104 is that the current main antenna performance is better than the current diversity antenna performance, the current state is maintained without antenna switching; if the comparison result is that the current main antenna performance is worse than the current diversity antenna performance, then step S105.

[0037] S105: Perform antenna switching, and use the antenna with better performance as the main antenna, and the antenna with poor performance as the diversity antenna.

[0038] The above steps S104 and S105 realize the selection of the antenna with the best performance as the main antenna. In practical applications, the comparison of antenna performance in step S104 can be to compare the signal reception performance of the antenna when it is working, or to compare the antenna performance when it is working. Other properties. And the comparison process can be real-time or periodic.

[0039] In addition, the conditions for antenna switching can be further set as: when the performance of the current diversity antenna is better than the performance of the current main antenna to a certain extent, the antenna switching is performed, that is, the performance of the current diversity antenna is better than the performance of the current main antenna. When the predetermined level is not exceeded, antenna switching is not performed to reduce the cost of antenna switching.

[0040] The above steps S101-S105 realize the intelligent switching of the antennas in the mobile terminal. The following takes the case where the mobile terminal includes three antennas as an example. The three antennas in the antenna group of the mobile terminal can be set at any position of the mobile terminal, such as figure 2 with image 3 As shown, figure 2 Yes figure 1 A schematic structural diagram of a mobile terminal in an embodiment of the antenna switching method shown, image 3 Yes figure 1 Another schematic diagram of the structure of the mobile terminal in an embodiment of the antenna switching method is shown.

[0041] in figure 2 Here, the mobile terminal 200 includes an antenna group 21, and the antenna group 21 includes a first antenna 211, a second antenna 212, and a third antenna 213. Among them, the first antenna 211 is arranged on the top of the mobile terminal 200, the second antenna 212 is arranged on the middle of the mobile terminal 200, and the third antenna 213 is arranged on the bottom of the mobile terminal 200.

[0042] Further, if the first antenna 211 is a full-frequency antenna, the second antenna 212 is a high-frequency antenna, and the third antenna 213 is a low-frequency antenna, the high-frequency antenna and the low-frequency antenna are relative concepts, for example, it may be a high-frequency antenna above 1 GHz. , Below 1GHz is a low-frequency antenna; it can also be a high-frequency antenna above 2GHz, and a low-frequency antenna below 2GHz.

[0043] For intelligent switching of a full-frequency antenna, a high-frequency antenna, and a low-frequency antenna, the antenna switching method of the foregoing embodiment can be applied. In step S101, the frequency band information of the environment where the mobile terminal is located is obtained; if the frequency band information of the environment where the mobile terminal is located is a high frequency band, then a full frequency antenna and a high frequency antenna are selected in step S102; if the frequency band information of the environment where the mobile terminal is located is a low frequency band, In step S103, a full-frequency antenna and a low-frequency antenna are selected.

[0044] in image 3 In this case, the mobile terminal 300 includes an antenna group 31, and the antenna group 31 includes a first antenna 311, a second antenna 312, and a third antenna 313. The first antenna 311 is disposed on the top of the mobile terminal 300, the second antenna 312 is disposed on the bottom left side of the mobile terminal 300, and the third antenna 313 is disposed on the bottom right side of the mobile terminal 300.

[0045] For the antenna switching of the mobile terminal 300, the antenna switching method of the above-mentioned embodiment can also be applied to obtain the user's holding information in step S101; if the user's holding information is left-handed, the first antenna 311 and the first antenna are selected in step S102. The third antenna 313; if the user's holding information is right-hand holding, the first antenna 311 and the second antenna 312 are selected in step S102.

[0046] for image 3 In the mobile terminal 300 shown, the first antenna 311 may also be a full-frequency antenna, the second antenna 312 is a high-frequency antenna, and the third antenna 313 is a low-frequency antenna.

[0047] It should be noted that the high-frequency antenna and the low-frequency antenna described above may be two parts of one antenna in physical structure, that is, the high-frequency antenna and the low-frequency antenna may be located at the bottom of the mobile terminal together. Therefore, for an antenna group of a mobile terminal including a full-frequency antenna, a high-frequency antenna, and a low-frequency antenna, the antenna group may have only two antennas in a physical sense, but in a functional sense, it is considered that there are three antennas.

[0048] The antenna switching method of the above mobile terminal can realize the intelligent switching of the mobile terminal antenna to make the optimal configuration for the use of the antenna, and select the antenna with better performance as the main antenna and the diversity antenna to optimize the communication capability of the mobile terminal.

[0049] When applying the above-mentioned antenna switching method of a mobile terminal, an executable program is usually used to represent its logical process, that is, each step of the antenna switching method, and a software system is constructed based on hardware equipment to run the executable program to realize the antenna switching method .

[0050] For the executable program, it is stored in a computer storage medium, which can be a floppy disk, hard disk, optical disk, memory card, etc., which can be read and written through an interface connection; it can also be a server, which can be read and written through a network connection. The executable program can be read and executed to implement the steps in the antenna switching method of the mobile terminal in the above embodiment.

[0051] For the software system, multiple modules are constructed in the mobile terminal of the present invention to implement multiple steps in the antenna switching method.

[0052] The acquisition module 41 is used to acquire the status information of the mobile terminal; the selection module 42 selects two antennas from the antenna group of the mobile terminal according to the status information; the selected two antennas are respectively used as the main antenna and the diversity through the switching module 44 Antenna; the comparison module 43 compares the performance of the current main antenna and the current diversity antenna; if the performance of the current main antenna is worse than the performance of the current diversity antenna, the antenna switch is performed through the switching module 44 to use the better performance antenna As the main antenna, the antenna with poor performance is used as the diversity antenna.

[0053] Each module of the antenna switching device 400 of this embodiment can implement the antenna switching method of the foregoing embodiment, and details are not repeated here.

[0054] For hardware equipment, the antenna switching device 400 includes a processor 51, please refer to Figure 5 , Figure 5 It is a schematic diagram of the structure of the hardware device of an embodiment of the antenna switching device of the mobile terminal of the present invention.

[0055] The processor 51 can obtain the status information of the mobile terminal, select two antennas from the antenna group of the mobile terminal according to the status information, and use the two antennas as the main antenna and the diversity antenna respectively. The processor 51 can also compare the performance of the current main antenna and the current diversity antenna when the main antenna and the diversity antenna are working; to switch the antenna when the performance of the current main antenna is worse than the performance of the current diversity antenna to compare the performance. The good antenna is used as the main antenna, and the poorer performance antenna is used as the diversity antenna.

[0056] The antenna switching device 400 may also include a memory 52 for storage support during the operation of the processor 51. The memory 52 may be a device of the antenna switching device 400 itself, or a memory in the mobile terminal, or a memory externally connected to the mobile terminal.

[0057] The antenna switching device 400 of this embodiment is used in a mobile terminal to realize intelligent switching of antennas in the mobile terminal and improve the communication performance of the mobile terminal.
