Specifically, when the signal that the earphone is inserted into the earphone interface is detected, the call mode is determined to be the earphone call mode; when the light sensor detects that the light changes from bright to dark, the call mode is determined to be the hand-held head mode; when it is detected that the mobile USB charging When the current and the earphone are plugged into the signal, make sure that the call mode is the USB charging earphone mode.

Step 102: Obtain the current call channel corresponding to the call instruction.

Among them, the call channel is different under different network standards and different frequency bands. Channels and frequencies are in one-to-one correspondence.

In practical applications, when the mobile terminal is registered in the network, the frequency band and channel corresponding to the network access can be recorded, wherein the channel is recorded in the form of a number.

Step 103: In the call mode of the mobile terminal, acquire the upper antenna weight value and the lower antenna weight value corresponding to the current call channel.

Therefore, when the signal strengths of the upper antenna and the lower antenna are equal, continuous switching back and forth between the upper and lower antennas can be solved, thereby reducing the quality of the call and the quality of data transmission.

Embodiment 2

Referring to FIG. 2, a flowchart of steps of an antenna switching method according to Embodiment 2 of the present invention is shown, which may specifically include the following steps:

Step 201 , for each network system in each call mode, test the total radiated power of the upper antenna, the total isotropic sensitivity of the upper antenna, the total radiated power of the lower antenna, and the total isotropic sensitivity of the lower antenna corresponding to the designated channel in each frequency band.

Among them, the network standard includes: GSM (Global System for Mobile Communication, global mobile communication network), CDMA (Code Division Multiple Access, code division multiple access), TDSCDMA (Time Division-Synchronous Code Division Multiple Access, time division synchronous code division multiple access) , WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access).

In the embodiment of the present invention, for GSM, channels 975, 38, and 124 in the frequency band EGSM900 and channels 512, 698, and 885 in the frequency band DCS1800 are respectively tested, wherein 975, 38, 124, 512, 698, and 885 are all channels. No., test channels of three typical frequencies of high, medium and low in each frequency band. For example, channels 975 and 512 are high frequency channels, channels 38 and 698 are intermediate frequency channels, and channels 124 and 885 are low frequency channels.

For my country's CDMA, the channels 37, 78, 119, 160, 201, 242, and 283 under the frequency band CDMA2000 were tested respectively. In practical applications, you can choose to test the high frequency channel 37, the intermediate frequency channel 160, and the low frequency channel 283. For international CDMA, the high frequency channel 384, the intermediate frequency channel 777 and the low frequency channel 1013 of the frequency band CDMA2000 are tested respectively.

For TDSCDMA, the channels 10054, 10087, and 10121 under the frequency band BAND34, the high-frequency channel 9404, the intermediate-frequency channel 9500, and the low-frequency channel 9596 under the BAND39 are tested respectively.

For WCDMA, test the high frequency channel 9612, the intermediate frequency channel 9750, and the low frequency channel 9888 under the frequency band BAND1 respectively.

It can be understood that some typical high, middle and low frequency channels are selected in the embodiments of the present invention, and other typical channels may also be selected in practical applications, which are not limited in the embodiments of the present invention.

The embodiments of the present invention predict antenna weighting values in various scenarios by testing actual application data. In practical applications, periodic testing can also be performed to ensure that the antenna weighting value is more reliable.

Step 202, for each designated channel, calculate the weighted value of the upper antenna according to the corresponding total radiated power of the upper antenna and the total omnidirectional sensitivity of the upper antenna, and calculate the weighted value of the upper antenna according to the corresponding total radiated power of the lower antenna and the total omnidirectional sensitivity of the lower antenna. Calculate the antenna weighting value.

It can be understood that the total radiated power of the antenna and the total omnidirectional sensitivity of the antenna both affect the transmission quality of the signal. The larger the total radiated power of the antenna, the better the transmission quality. The smaller the weighted value; the greater the total omnidirectional sensitivity of the antenna, the better the transmission quality; the larger the antenna weighted value, the smaller the total omnidirectional sensitivity, the worse the transmission quality, and the smaller the antenna weighted value. Therefore, when the total radiated power and total omnidirectional sensitivity of the antenna are both large, the weighted value of the antenna is large, and the antenna is the optimal antenna.

Optionally, in another embodiment of the present invention, step 202 includes sub-steps 2021 to 2024:

Sub-step 2021, divide the absolute value of the total omnidirectional sensitivity of the upper antenna and the absolute value of the total omnidirectional sensitivity of the lower antenna by the first conversion value to obtain the total omnidirectional sensitivity of the first upper antenna and the total omnidirectional sensitivity of the first lower antenna .

Specifically, the total omnidirectional sensitivity of the first upper antenna and the total omnidirectional sensitivity of the first lower antenna can be calculated according to the following formula (1):

S _f =|S _t |/T _f (1)

Wherein, S _f is the total omnidirectional sensitivity of the first upper antenna or the total omnidirectional sensitivity of the first lower antenna, S _t is the total omnidirectional sensitivity of the upper antenna or the total omnidirectional sensitivity of the lower antenna, and the first conversion value T _f is an empirical value. Since the total omnidirectional sensitivity is several times higher than the total radiated power, in order to not ignore the influence of the total radiated power when calculating the antenna weighting value, the total omnidirectional sensitivity is divided by the first conversion value. In this embodiment of the present invention, the first conversion value is 4. It can be understood that the first conversion value may float up or down 4, which is not limited in this embodiment of the present invention. Furthermore, the total radiated power can also be multiplied by the first conversion value, so that the total radiated power and the total isotropic sensitivity are comparable in magnitude.

Sub-step 2022, multiply the total omnidirectional sensitivity of the first upper antenna and the total omnidirectional sensitivity of the first lower antenna by a first weighting parameter to obtain the first result of the upper antenna and the first result of the lower antenna.

Specifically, both the first result of the upper antenna and the first result of the lower antenna can be calculated according to the following formula (2):

R _f =S _f ·P _f =|S _t |/T _f ·P _f (2)

Wherein, R _f is the first result of the upper antenna or the first result of the lower antenna, S _f is the total omnidirectional sensitivity of the first upper antenna or the total omnidirectional sensitivity of the first lower antenna, and P _f is the first weighting parameter.

In the embodiment of the present invention, the weighting parameter is used to modify the proportion of the influence of the total omnidirectional sensitivity and the total radiated power on the antenna weighting value. Considering that the total omnidirectional sensitivity has a greater influence on the call quality than the total radiated power, in practical applications, the weighting parameter for the total omnidirectional sensitivity is larger, and the weighting parameter for the total radiated power is smaller.

Sub-step 2023, multiply the total radiated power of the upper antenna and the total radiated power of the lower antenna by the second weighting parameter to obtain the second result of the upper antenna and the second result of the lower antenna.

Specifically, the second result of the upper antenna and the second result of the lower antenna can be calculated according to the following formula (3):

R _s =F _t *P _s (3)

Wherein, R _s is the second result of the upper antenna or the second result of the lower antenna, R _s is the total radiated power of the upper antenna or the total radiated power of the lower antenna, and P _s is the second weighting parameter.

In a specific application, both the second weighting parameter and the first weighting parameter are between 0 and 1. For example, the first weighting parameter is 0.6 and the second weighting parameter is 0.4. It can be understood that the first weighting parameter and the second weighting parameter may be adjusted according to an actual application scenario, which is not limited in this embodiment of the present invention.

Sub-step 2024, multiply the first result of the upper antenna plus the second result of the upper antenna by the second conversion value, and multiply the first result of the lower antenna plus the second result of the lower antenna by The second conversion value is to obtain the weighted value of the upper antenna and the weighted value of the lower antenna.

Specifically, the upper antenna weighted value and the lower antenna weighted value can be calculated according to the following formula (4):

R=(R _f +R _s )*T _s =(|S _t |/T _f ·P _f +F _t *P _s )*T _s (4)

Among them, R is the weighted value of the upper antenna or the weighted value of the lower antenna, R _f is the first result of the upper antenna or the first result of the lower antenna, R _s is the second result of the upper antenna or the second result of the lower antenna, and T _s is the second conversion value, the second conversion value converts the sum of the first result and the second result to an integer for storage.

In the embodiment of the present invention, as shown in Table 1, it is an example of the lower/lower antenna weighting value of the GSM standard in the hand-held head mode. For the 975-channel, 38-channel and 124-channel under the frequency band EGSM900, the upper and lower antennas of the six-channel 512-channel, 698-channel and 885-channel under the frequency band DCS1800, according to the total radiated power (TRP, Total Radiated Power) and the total The antenna weighting value is obtained by calculating the Total Isotropic Sensitivity (TIS, Total Isotropic Sensitivity). In this example, the weight of TRP is uniformly 0.4, and the weight of TIS is uniformly 0.6, and the weighted value is calculated according to formula (4). In addition, for the convenience of storage, the antenna weight value is multiplied by 10 and converted to an integer. It will be appreciated that other fixed data may also be used to convert the antenna weights to integers.

It can be understood that Table 1 is only an example of the embodiment of the present invention, and the embodiment of the present invention is also applicable to other call modes, frequency bands, and channels.

Table 1

Step 203: Store the upper antenna weight value and the lower antenna weight value corresponding to each designated channel in a first designated storage location of the mobile terminal.

Wherein, the first designated storage location is any location on the memory of the mobile terminal. It can be understood that the size of the second designated storage location may be allocated according to an actual application scenario, which is not limited in this embodiment of the present invention.

In this embodiment of the present invention, in order to more conveniently obtain the weighted value of the upper antenna and the weighted value of the lower antenna, the weighted value of the upper antenna and the weighted value of the lower antenna are stored in the memory of the mobile terminal. Reading on the terminal can improve the efficiency of determining the optimal antenna.

Specifically, the upper antenna weighted value and the lower antenna weighted value are respectively stored according to the call mode and the channel. For example, if the call mode number is 0 for the headset call mode, 1 for the handheld head mode, and 2 for the USB charging headset mode, and stored in the format {call mode, channel, upper antenna weight, lower antenna weight}, then The stored result in Table 2A includes 6 records: {1, 975, 267, 257}, {1, 38, 266, 260}, {1, 124, 264, 259}, {1, 512, 255, 263} , {1, 698, 256, 265}, {1, 885, 256, 261}.

Step 204, when receiving the registration confirmation information, record the channel corresponding to the mobile terminal.

In the embodiment of the present invention, when the user registers to the network, the channel where the mobile terminal is located is stored in the memory of the mobile terminal, so as to be directly read from the memory of the mobile terminal during use, thereby improving the efficiency of determining the optimal antenna. Specifically, the channel number and frequency are stored in the memory of the mobile terminal.

Optionally, in another embodiment of the present invention, step 202 includes sub-steps 2021 to 2024:

Sub-step 2041, obtain the channel number corresponding to the mobile terminal from the registration confirmation information.

When registering the mobile terminal into the network, the core network will send the registration confirmation information to the mobile terminal, which carries the relevant information after the mobile terminal is registered and connected to the network, including the frequency band and channel number where it resides.

Sub-step 2042: Store the channel number corresponding to the mobile terminal in the second designated storage location of the mobile terminal.

Wherein, the second designated storage location may be any location in the memory of the mobile terminal. Since the channel numbers under different network standards and frequency bands will not be repeated, the channel can be uniquely determined only by the channel number.

It can be understood that the size of the second designated storage location may be allocated according to an actual application scenario, which is not limited in this embodiment of the present invention.

Step 205, when receiving the call instruction, determine the call mode of the mobile terminal.

For step 205, reference may be made to the detailed description of step 101, which will not be repeated here.

Step 206: Read the channel number from the second designated storage location to obtain the current call channel.

For sub-step 2041, the channel number is stored in the second designated location, and step 206 reads the channel number from the second designated location.

Step 207: In the call mode of the mobile terminal, acquire the upper antenna weight value and the lower antenna weight value corresponding to the current call channel.

Specifically, a matching storage record is found according to the call mode number and the channel number.

Optionally, in another embodiment of the present invention, step 207 includes sub-step 2071:

Sub-step 2071, in the call mode of the mobile terminal, read the upper antenna weight value and the lower antenna weight value corresponding to the current call channel from the first designated storage location of the mobile terminal.

For step 203, the upper and lower antenna weights are stored in the first storage location of the memory of the mobile terminal, and sub-step 2071 reads the upper and lower antenna weights from the first storage location.

Optionally, in another embodiment of the present invention, step 207 includes sub-steps 2072 to 2073:

Sub-step 2072, in the call mode of the mobile terminal, determine the channel with the closest frequency to the current call channel as the target channel.

Since the antenna weights of some typical channels are stored, when the current call channel cannot be found in the storage, the channel closest to the current call channel is found according to the frequency, and the corresponding antenna weight value is used as the antenna weight value of the current call channel. .

Sub-step 2073, respectively use the upper antenna weight value and the lower antenna weight value corresponding to the target channel as the upper antenna weight value and the lower antenna weight value corresponding to the current communication channel.

It can be understood that obtaining the upper antenna weight value and the lower antenna weight value from the records pre-stored in the mobile terminal can effectively improve the efficiency of determining the optimal antenna.

Step 208: Determine the optimal antenna according to the weighted value of the upper antenna and the weighted value of the lower antenna.

For step 208, reference may be made to the detailed description of step 104, which will not be repeated here.

Optionally, in another embodiment of the present invention, step 208 includes sub-steps 2081 to 2082:

Sub-step 2081, if the weighted value of the upper antenna is greater than the weighted value of the lower antenna, determine that the upper antenna is the optimal antenna.

It can be understood that when the weighted value of the upper antenna is greater than the weighted value of the lower antenna, the total radiated power and total omnidirectional sensitivity of the upper antenna are better, and the upper antenna has a better ability to transmit signals.

Sub-step 2082, if the weighted value of the lower antenna is greater than the weighted value of the upper antenna, determine that the lower antenna is the optimal antenna.

It can be understood that when the weighted value of the lower antenna is greater than the weighted value of the upper antenna, the total radiated power and total omnidirectional sensitivity of the lower antenna are better, and the lower antenna has a better ability to transmit signals.

Step 209, switch to the optimal antenna for call transmission until the current call ends.

For step 209, reference may be made to the detailed description of step 105, which will not be repeated here.

Optionally, in another embodiment of the present invention, step 209 includes sub-step 2091:

Sub-step 2091, lock the optimal antenna until the end of the call.

Locking the optimal antenna until the end of the call ensures that there will be no problem of poor call quality due to antenna switching during the call.

Step 210, when an instruction to end the call is received, unlock the optimal antenna.

For the sub-step 2091, the optimal antenna is locked until the end of the current call, and in step 210, the lock is released at the end of the call, so as to proceed to step 201 to re-determine the optimal antenna for the next call.

In the embodiment of the present invention, when a call instruction is received, the call mode of the mobile terminal is determined; the current call channel corresponding to the call instruction is obtained; in the call mode of the mobile terminal, the current call channel corresponding to the current call channel is obtained The upper antenna weighted value and the lower antenna weighted value are determined; the optimal antenna is determined according to the upper antenna weighted value and the lower antenna weighted value; and the call is transferred to the optimal antenna until the call ends. Therefore, when the signal strengths of the upper antenna and the lower antenna are equal, continuous switching back and forth between the upper and lower antennas can be solved, thereby reducing the quality of the call and the quality of data transmission. In addition, the antenna weighting value can be obtained by pre-testing and calculation, and stored in the mobile terminal, thereby improving the efficiency of antenna switching.
