The embodiment of the application provides electronic equipment. The electronic device can be a smart phone, a tablet computer and the like. In some embodiments, referring to fig. 1, the electronic device 100 includes a display screen 10, a middle frame 20, a circuit board 30, a battery 40, and a rear cover 50.
Wherein the display screen 10 is mounted on the rear cover 50 to form a display surface of the electronic device 100.

In some embodiments, a glass cover plate may be disposed over the display screen 10. Wherein, the glass cover plate can cover the display screen 10 to protect the display screen 10 and prevent the display screen 10 from being scratched or damaged by water.
In some embodiments, as shown in FIG. 1, the display screen 10 may include a display area 11 and a non-display area 12. The display area 11 performs a display function of the display screen 10 for displaying information such as images and texts. The non-display area 12 does not display information.

In some embodiments, the non-display area 12 may include at least one area located at upper and lower portions of the display area 11.
In some embodiments, as shown in FIG. 2, the display screen 10 may be a full-face screen. At this time, the display screen 10 may display information in a full screen, so that the electronic apparatus 100 has a large screen occupation ratio. The display screen 10 comprises only the display area 11 and no non-display area. At this time, functional modules such as a camera and a proximity sensor in the electronic apparatus 100 may be hidden under the display screen 10, and the fingerprint identification module of the electronic apparatus 100 may be disposed on the back of the electronic apparatus 100.
The middle frame 20 may have a thin plate-like or sheet-like structure, or may have a hollow frame structure. The middle frame 20 can be accommodated in the accommodating space formed by the display screen 10 and the rear cover 50. The middle frame 20 is used for providing a supporting function for the electronic components or the functional modules in the electronic device 100, so as to mount the electronic components or the functional modules in the electronic device together. For example, functional modules such as a camera, a receiver, a circuit board, and a battery in the electronic apparatus may be mounted on the center frame 20 for fixing. In some embodiments, the material of the middle frame 20 may include metal or plastic.
The circuit board 30 is mounted inside the receiving space. For example, the circuit board 30 may be mounted on the middle frame 20 and received in the receiving space together with the middle frame 20. The circuit board 30 may be a motherboard of the electronic device 100. The circuit board 30 is provided with a grounding point to realize grounding of the circuit board 30. One or more of a motor, a microphone, a speaker, a receiver, an earphone interface, a universal serial bus interface (USB interface), a camera, a proximity sensor, an ambient light sensor, a gyroscope, and a processor may be integrated on the circuit board 30. Meanwhile, the display screen 10 may be electrically connected to the circuit board 30.
In some embodiments, display control circuitry is disposed on the circuit board 30. The display control circuit outputs an electrical signal to the display screen 10 to control the display screen 10 to display information.
The battery 40 is mounted inside the receiving space. For example, the battery 40 may be mounted on the middle frame 20 and be received in the receiving space together with the middle frame 20. The battery 40 may be electrically connected to the circuit board 30 to enable the battery 40 to power the electronic device 100. The circuit board 30 may be provided thereon with a power management circuit. The power management circuit is used to distribute the voltage provided by the battery 40 to the various electronic components in the electronic device 100.
The rear cover 50 is used to form an outer contour of the electronic device 100. The rear cover 50 may be integrally formed. In the forming process of the rear cover 50, a rear camera hole, a fingerprint identification module mounting hole and the like can be formed in the rear cover 50.
In the present embodiment, with continued reference to fig. 2, the electronic device 100 further includes a first antenna 61 and a second antenna 62. The first antenna 61 and the second antenna 62 are electrically connected to the circuit board 30 in the electronic device 100. The first antenna 61 and the second antenna 62 may be disposed on the middle frame 20 or on the rear cover 50. The first antenna 61 and the second antenna 62 are arranged at intervals. For example, the first antenna 61 may be disposed at the upper left corner of the electronic device 100, and the second antenna 62 may be disposed at the lower right corner of the electronic device 100.
Wherein the first antenna 61 and the second antenna 62 are used for transmitting and/or receiving signals. For example, the first antenna 61 and the second antenna 62 may be used for transmitting and/or receiving radio frequency signals. It should be noted that the first antenna 61 and the second antenna 62 can each perform transmission and reception of signals separately.
In the process of the electronic device 100 communicating with a base station or other electronic devices, one of the first antenna 61 and the second antenna 62 serves as a main set antenna, and the other serves as a diversity antenna. And, the main set antenna and the diversity antenna may be switched with each other. Wherein the main set antennas perform transmission and reception of signals simultaneously, and the diversity antennas receive only signals without transmitting signals.
The embodiment of the present application provides an antenna switching method, which may be applied to the electronic device 100. As shown in fig. 3, the antenna switching method may include the following steps:
the first antenna transmits a connection request to the base station at a first transmit power 110.
Wherein the electronic device comprises a first antenna and a second antenna. In an initial state, one of the first antenna and the second antenna is used as a main set antenna to transmit and receive signals; and the other as a diversity antenna, performing reception of the signal. For example, in the initial state, the first antenna serves as a main set antenna, and the second antenna serves as a diversity antenna.
When the electronic equipment needs to establish connection with the base station, the first antenna sends a connection request to the base station at a first transmission power. Wherein the first transmission power may be a preset power. For example, the first transmission power may be an initial transmission power defined by the base station, or may be a minimum transmission power defined by the base station when the electronic device transmits information to the base station. For example, the first transmit power may be 15dBm (decibel-milliwatts). The connection request represents a first piece of information sent by the electronic equipment to the base station in the process of establishing connection between the electronic equipment and the base station.
There are many situations in which an electronic device needs to establish a connection with a base station. For example, when the electronic device is switched from an idle state to a connected state, the first antenna transmits a connection request to the base station at a first transmission power. The idle state indicates that the electronic device only performs a listening task, that is, the electronic device only receives information (e.g., broadcast information of the base station) transmitted by the base station, and does not transmit information to the base station. The connection state indicates a state in which data interaction exists between the electronic device and the base station, and the electronic device needs to send information to the base station in the connection state, for example, the electronic device needs to send uplink data to the base station.
For another example, when the electronic device is handed over from a connected base station to another new base station, the electronic device needs to establish a connection with the new base station, and the first antenna transmits a connection request to the new base station with the first transmission power.
120, if the response information of the base station is not received within a first preset time period, the first antenna sends a connection request to the base station with a maximum transmission power, and the first transmission power is smaller than the maximum transmission power.
It should be noted that, in an ideal state, the electronic device sends a connection request to the base station, and after the base station receives the connection request, the base station sends a response message to the electronic device. The response information indicates that the base station receives the connection request sent by the electronic equipment.
However, due to the influence of the actual communication environment, for example, when there is interference caused by other devices to the first antenna of the electronic device, or when the first antenna in the electronic device is blocked, the connection request transmitted by the first antenna in the electronic device may not be successfully transmitted to the base station. At this time, the base station cannot receive the connection request transmitted by the first antenna, and the base station does not transmit the response information to the electronic device.
After the first antenna in the electronic device sends a connection request to the base station, the electronic device determines whether response information of the base station is received within a first preset time period. The first preset time period may be a preset time period value, for example, the first preset time period may be 20ms (milliseconds).
And if the response information of the base station is not received within the first preset time, the first antenna is represented to fail to successfully send the connection request to the base station. At this time, the electronic device controls the first antenna to transmit a connection request to the base station at the maximum transmission power. Wherein the first transmit power is less than the maximum transmit power.
It should be noted that, when the first antenna sends a connection request to a base station, the transmission power of the first antenna may be adjusted within a range. For example, the transmit power of the first antenna may be adjusted between 12dBm and 23 dBm. The first antenna has a maximum transmit power. For example, if the maximum transmission power of the first antenna is 23dBm, the electronic device controls the first antenna to send a connection request to the base station with a transmission power of 23 dBm.
In addition, if the response information of the base station is received within the first preset time period, which indicates that the first antenna successfully sends the connection request to the base station, the electronic device may establish a connection with the base station at this time.
130, when the first antenna sends a connection request to the base station with the maximum transmission power, if the response information of the base station is still not received within a second preset time period, switching to the second antenna to send the connection request to the base station.
And when the first antenna sends a connection request to the base station at the maximum transmitting power, the electronic equipment judges whether response information of the base station is received within a second preset time period again. The second preset duration may be a preset duration value, and the second preset duration may be equal to the first preset duration or may not be equal to the first preset duration. For example, the second preset time period may be 25ms (milliseconds).
If the response information of the base station is still not received within the second preset time length, the first antenna still fails to successfully send the connection request to the base station. At this time, the electronic device switches to the second antenna to transmit the connection request to the base station. That is, the second antenna is switched to a main set antenna, and the first antenna is switched to a diversity antenna. At this time, the second antenna sends the connection request to the base station, and the first antenna and the second antenna still receive signals simultaneously.
In some embodiments, when switching to the second antenna to send the connection request to the base station, the second antenna may send the connection request to the base station with the first transmission power, the transmission power of the second antenna may also be greater than the first transmission power, or the second antenna may send the connection request to the base station with the maximum transmission power of the second antenna.
It can be understood that, because the first antenna and the second antenna are disposed at different positions on the electronic device, the interference or shielding conditions suffered by the first antenna and the second antenna are different. When the first antenna sends the connection request to the base station with the maximum transmitting power and still does not receive the response information of the base station, namely the connection with the base station can not be established, the second antenna is switched to send the connection request to the base station, and the connection with the base station can be established through the second antenna, so that the success rate of accessing the electronic equipment to the base station can be improved.
In some embodiments, referring to fig. 7, a processor in the electronic device may be coupled to the first antenna and the second antenna, respectively, by toggling a switch. When the second antenna needs to be switched to send a connection request to the base station, the processor can be switched to be connected with the second antenna through the switch, so that the second antenna is switched to be the main set antenna.
In some embodiments, as shown in fig. 4, the antenna switching method further includes the following steps:
140, when the first antenna sends a connection request to the base station with the maximum transmission power, if the response message of the base station is received within a second preset time period, reducing the transmission power of the first antenna and sending a message from the first antenna to the base station.
When the first antenna sends the connection request to the base station with the maximum transmission power, if the response information of the base station is received within the second preset time period, the first antenna successfully sends the connection request to the base station, and at this time, the transmission power of the first antenna may be reduced and the first antenna sends information to the base station. The information sent to the base station by the first antenna after reducing the transmission power may include other information required for the electronic device to establish a connection with the base station, and information sent during communication after the electronic device establishes a connection with the base station.
It can be understood that after the transmission power of the first antenna is reduced, normal communication between the electronic device and the base station can be ensured, power consumption of the electronic device can be reduced, and cruising ability of the electronic device can be improved.
In some embodiments, as shown in fig. 5, when the first antenna sends the connection request to the base station with the maximum transmission power in step 140, if the response message of the base station is received within a second preset time period, the method reduces the transmission power of the first antenna and sends a message from the first antenna to the base station, including the following steps:
141, when the first antenna sends a connection request to the base station with the maximum transmission power, if the response information of the base station is received within a second preset time, obtaining a preset power reduction rate;
142, calculating a second transmitting power according to the maximum transmitting power and a preset power reduction rate;
143, the first antenna transmits information to the base station at the second transmit power.
The preset power reduction rate may be a value pre-stored in the electronic device. The preset power reduction rate represents the magnitude of the reduction of the transmission power of the first antenna. The preset power reduction rate is less than 1. For example, the preset power reduction magnification is 0.5.
And when the first antenna sends a connection request to the base station at the maximum transmitting power, if response information of the base station is received within a second preset time, acquiring a preset power reduction rate. And then, the electronic equipment calculates second transmission power according to the maximum transmission power and a preset power reduction rate, and controls the first antenna to send information to the base station at the second transmission power. Wherein the second transmit power is less than the maximum transmit power. Thus, the first antenna may transmit information to the base station at a power value less than the maximum transmit power.
In some embodiments, in step 142, when calculating the second transmission power according to the maximum transmission power and the preset power reduction rate, the electronic device performs calculation according to the following formula:
P2＝Pmax×(1-k)
wherein, P2Is the second transmission power, PmaxAnd k is the preset power reduction multiplying factor for the maximum transmitting power.
For example, Pmax23dBm, k 0.5, the calculated second transmitting power P2And 11.5 dBm.
In some embodiments, as shown in fig. 6, when the first antenna sends the connection request to the base station with the maximum transmission power in step 140, if the response message of the base station is received within the second preset time period, the method reduces the transmission power of the first antenna and sends a message from the first antenna to the base station, including the following steps:
144, when the first antenna sends a connection request to the base station with the maximum transmission power, if the response information of the base station is received within a second preset time, obtaining a preset power reduction value;
145, calculating a third transmit power according to the maximum transmit power and a preset power reduction value;
146, the first antenna sends information to the base station at the third transmit power.
Wherein the preset power reduction value may be a power value pre-stored in the electronic device. The preset power reduction value represents an amount of reduction of the transmission power of the first antenna. The preset power reduction value is less than the maximum transmission power. For example, if the maximum transmission power of the first antenna is 23dBm, the predetermined power reduction amount may be 12 dBm.
And when the first antenna sends a connection request to the base station at the maximum transmitting power, if response information of the base station is received within a second preset time, acquiring a preset power reduction value. And then, the electronic equipment calculates third transmitting power according to the maximum transmitting power and a preset power reduction value, and controls the first antenna to transmit information to the base station at the third transmitting power. Wherein the third transmit power is less than the maximum transmit power. Thus, the first antenna may transmit information to the base station at a power value less than the maximum transmit power.
In some embodiments, when calculating the third transmit power according to the maximum transmit power and the preset power reduction value, step 145, the electronic device calculates according to the following formula:
P3＝Pmax-△P
wherein, P3Is the third transmission power, PmaxFor the maximum transmit power, Δ P is the preset power reduction value.
For example, Pmax23dBm and Δ P of 12dBm, the third transmitting power P is calculated3And 11 dBm.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, the antenna switching method provided in the embodiment of the present application includes: a first antenna sends a connection request to a base station with a first transmission power; if the response information of the base station is not received within a first preset time length, the first antenna sends a connection request to the base station at the maximum transmitting power; when the first antenna sends a connection request to a base station with the maximum transmitting power, if the response information of the base station is still not received within a second preset time length, switching to the second antenna to send the connection request to the base station. In the antenna switching method, when the first antenna sends the connection request to the base station with the maximum transmitting power and still does not receive the response information of the base station, namely the first antenna still cannot be connected with the base station, the second antenna is switched to send the connection request to the base station, and the connection can be established with the base station through the second antenna, so that the success rate of accessing the electronic equipment to the base station can be improved.
The embodiment of the present application further provides an antenna switching apparatus, which may be integrated in the electronic device 100.
As shown in fig. 8, the antenna switching apparatus 200 may include: a sending module 201 and a switching module 202.
A sending module 201, configured to control the first antenna to send the connection request to the base station with the first transmission power.
Wherein the electronic device comprises a first antenna and a second antenna. In an initial state, one of the first antenna and the second antenna is used as a main set antenna to transmit and receive signals; and the other as a diversity antenna, performing reception of the signal. For example, in the initial state, the first antenna serves as a main set antenna, and the second antenna serves as a diversity antenna.
When the electronic device needs to establish a connection with the base station, the sending module 201 controls the first antenna to send a connection request to the base station with a first sending power. Wherein the first transmission power may be a preset power. For example, the first transmission power may be an initial transmission power defined by the base station, or may be a minimum transmission power defined by the base station when the electronic device transmits information to the base station. For example, the first transmit power may be 15dBm (decibel-milliwatts). The connection request represents a first piece of information sent by the electronic equipment to the base station in the process of establishing connection between the electronic equipment and the base station.
There are many situations in which an electronic device needs to establish a connection with a base station. For example, when the electronic device transitions from the idle state to the connected state, the sending module 201 controls the first antenna to send the connection request to the base station with the first transmission power. The idle state indicates that the electronic device only performs a listening task, that is, the electronic device only receives information (e.g., broadcast information of the base station) transmitted by the base station, and does not transmit information to the base station. The connection state indicates a state in which data interaction exists between the electronic device and the base station, and the electronic device needs to send information to the base station in the connection state, for example, the electronic device needs to send uplink data to the base station.
For another example, when the electronic device is switched from one connected base station to another new base station, the electronic device needs to establish a connection with the new base station, and the sending module 201 controls the first antenna to send a connection request to the new base station with the first sending power.
The sending module 201 is further configured to control the first antenna to send a connection request to the base station with a maximum transmission power if the response information of the base station is not received within a first preset time period, where the first transmission power is smaller than the maximum transmission power.
It should be noted that, in an ideal state, the electronic device sends a connection request to the base station, and after the base station receives the connection request, the base station sends a response message to the electronic device. The response information indicates that the base station receives the connection request sent by the electronic equipment.
However, due to the influence of the actual communication environment, for example, when there is interference caused by other devices to the first antenna of the electronic device, or when the first antenna in the electronic device is blocked, the connection request transmitted by the first antenna in the electronic device may not be successfully transmitted to the base station. At this time, the base station cannot receive the connection request transmitted by the first antenna, and the base station does not transmit the response information to the electronic device.
After the sending module 201 controls the first antenna to send a connection request to the base station, the sending module 201 determines whether response information of the base station is received within a first preset time period. The first preset time period may be a preset time period value, for example, the first preset time period may be 20ms (milliseconds).
And if the response information of the base station is not received within the first preset time, the first antenna is represented to fail to successfully send the connection request to the base station. At this time, the sending module 201 controls the first antenna to send a connection request to the base station with the maximum transmission power. Wherein the first transmit power is less than the maximum transmit power.
It should be noted that, when the first antenna sends a connection request to a base station, the transmission power of the first antenna may be adjusted within a range. For example, the transmit power of the first antenna may be adjusted between 12dBm and 23 dBm. The first antenna has a maximum transmit power. For example, if the maximum transmission power of the first antenna is 23dBm, the sending module 201 controls the first antenna to send the connection request to the base station with the transmission power of 23 dBm.
In addition, if the response information of the base station is received within the first preset time period, which indicates that the first antenna successfully sends the connection request to the base station, the electronic device may establish a connection with the base station at this time.
A switching module 202, configured to switch to the second antenna to send the connection request to the base station when the first antenna sends the connection request to the base station with the maximum transmit power and if the response information of the base station is still not received within a second preset time period.
When the first antenna sends a connection request to the base station with the maximum transmission power, the sending module 201 determines again whether response information of the base station is received within a second preset time period. The second preset duration may be a preset duration value, and the second preset duration may be equal to the first preset duration or may not be equal to the first preset duration. For example, the second preset time period may be 25ms (milliseconds).
If the response information of the base station is still not received within the second preset time length, the first antenna still fails to successfully send the connection request to the base station. At this time, the switching module 202 switches to send the connection request to the base station for the second antenna. That is, the second antenna is switched to a main set antenna, and the first antenna is switched to a diversity antenna. At this time, the second antenna sends the connection request to the base station, and the first antenna and the second antenna still receive signals simultaneously.
In some embodiments, when switching to the second antenna to send the connection request to the base station, the second antenna may send the connection request to the base station with the first transmission power, the transmission power of the second antenna may also be greater than the first transmission power, or the second antenna may send the connection request to the base station with the maximum transmission power of the second antenna.
It can be understood that, because the first antenna and the second antenna are disposed at different positions on the electronic device, the interference or shielding conditions suffered by the first antenna and the second antenna are different. When the first antenna sends the connection request to the base station with the maximum transmitting power and still does not receive the response information of the base station, namely the connection with the base station can not be established, the second antenna is switched to send the connection request to the base station, and the connection with the base station can be established through the second antenna, so that the success rate of accessing the electronic equipment to the base station can be improved.
In some embodiments, as shown in fig. 9, the antenna switching apparatus 200 further includes a power control module 203.
A power control module 203, configured to, when the first antenna sends the connection request to the base station with the maximum transmit power, if the response information of the base station is received within a second preset time period, decrease the transmit power of the first antenna and send information to the base station through the first antenna.
When the first antenna sends a connection request to the base station with the maximum transmission power, if the response message of the base station is received within the second preset time period, which indicates that the first antenna successfully sends the connection request to the base station, the power control module 203 controls to reduce the transmission power of the first antenna and sends a message from the first antenna to the base station. The information sent to the base station by the first antenna after reducing the transmission power may include other information required for the electronic device to establish a connection with the base station, and information sent during communication after the electronic device establishes a connection with the base station.
It can be understood that after the transmission power of the first antenna is reduced, normal communication between the electronic device and the base station can be ensured, power consumption of the electronic device can be reduced, and cruising ability of the electronic device can be improved.
In some embodiments, the power control module 203 is configured to perform the following steps:
when the first antenna sends a connection request to a base station at the maximum transmitting power, if response information of the base station is received within a second preset time, acquiring a preset power reduction rate;
calculating second transmitting power according to the maximum transmitting power and a preset power reduction rate;
and the first antenna sends information to the base station at the second transmission power.
The preset power reduction rate may be a value pre-stored in the electronic device. The preset power reduction rate represents the magnitude of the reduction of the transmission power of the first antenna. The preset power reduction rate is less than 1. For example, the preset power reduction magnification is 0.5.
When the first antenna sends a connection request to the base station with the maximum transmission power, if the response information of the base station is received within a second preset time period, the power control module 203 obtains a preset power reduction rate. Then, the power control module 203 calculates a second transmission power according to the maximum transmission power and a preset power reduction rate, and controls the first antenna to send information to the base station at the second transmission power. Wherein the second transmit power is less than the maximum transmit power. Thus, the first antenna may transmit information to the base station at a power value less than the maximum transmit power.
In some embodiments, when the second transmission power is calculated according to the maximum transmission power and a preset power reduction rate, the power control module 203 calculates according to the following formula:
P2＝Pmax×(1-k)
wherein, P2Is the second transmission power, PmaxAnd k is the preset power reduction multiplying factor for the maximum transmitting power.
For example, Pmax23dBm, k 0.5, the calculated second transmitting power P2And 11.5 dBm.
In some embodiments, the power control module 203 is configured to perform the following steps:
when the first antenna sends a connection request to a base station at the maximum transmitting power, if response information of the base station is received within a second preset time, a preset power reduction value is obtained;
calculating a third transmitting power according to the maximum transmitting power and a preset power reduction value;
and the first antenna sends information to the base station at the third transmission power.
Wherein the preset power reduction value may be a power value pre-stored in the electronic device. The preset power reduction value represents an amount of reduction of the transmission power of the first antenna. The preset power reduction value is less than the maximum transmission power. For example, if the maximum transmission power of the first antenna is 23dBm, the predetermined power reduction amount may be 12 dBm.
When the first antenna sends a connection request to the base station with the maximum transmission power, if the response information of the base station is received within a second preset time period, the power control module 203 obtains a preset power reduction value. Then, the power control module 203 calculates a third transmit power according to the maximum transmit power and a preset power reduction value, and controls the first antenna to transmit information to the base station at the third transmit power. Wherein the third transmit power is less than the maximum transmit power. Thus, the first antenna may transmit information to the base station at a power value less than the maximum transmit power.
In some embodiments, when calculating the third transmit power according to the maximum transmit power and the preset power reduction value, the power control module 203 calculates according to the following formula:
P3＝Pmax-△P
wherein, P3Is the third transmission power, PmaxFor the maximum transmit power, Δ P is the preset power reduction value.
For example, Pmax23dBm and Δ P of 12dBm, the third transmitting power P is calculated3And 11 dBm.
In specific implementation, the modules may be implemented as independent entities, or may be combined arbitrarily and implemented as one or several entities.
As can be seen from the above, the antenna switching apparatus 200 according to the embodiment of the present application controls the first antenna to transmit the connection request to the base station with the first transmission power through the transmitting module 201; if the response message of the base station is not received within a first preset time period, the sending module 201 controls the first antenna to send a connection request to the base station with the maximum transmitting power; when the first antenna sends a connection request to a base station with the maximum transmission power, if the response information of the base station is still not received within a second preset time period, the switching module 202 switches to the second antenna to send the connection request to the base station. In the antenna switching apparatus 200, when the first antenna sends the connection request to the base station with the maximum transmission power and still does not receive the response information of the base station, that is, when the connection with the base station still cannot be established, the first antenna is switched to the second antenna to send the connection request to the base station, and the connection with the base station can be established through the second antenna, so that the success rate of accessing the electronic device to the base station can be improved.
