The following describes in detail the antenna switching provided by the embodiments of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
The antenna switching method is applied to an electronic device, the electronic device includes M antennas, M is an integer greater than 1, fig. 1 is a flowchart of the antenna switching method provided in the embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
The M antennas included in the electronic device may include two types of antennas, which are a main antenna and an auxiliary antenna, respectively, and the first antenna may be the main antenna or the auxiliary antenna, which is not specifically limited herein.
The main antenna and the auxiliary antenna usually have a certain radiation performance difference, and the radiation performance of the main antenna is usually better than that of the auxiliary antenna. Therefore, the antenna for the electronic device to communicate usually defaults to the main antenna of the M antennas, i.e. in an alternative embodiment, the first antenna may be the main antenna of the M antennas.
In general, the electronic device may include a main antenna, and the number of the auxiliary antennas may be set according to actual situations, for example, the electronic device includes 4 antennas, the antenna 1 may be set as the main antenna, and the antenna 2, the antenna 3, and the antenna 4 are all set as the auxiliary antennas.
Under the condition that electronic equipment communicates through the antenna, under some use scenes, because reasons such as antenna shelter from and surrounding environment, can greatly influence the antenna and to the receipt of signal, and when electronic equipment was in different use scenes, the influence degree to antenna signal reception can be different. In this case, the antenna needs to be switched to another antenna for communication, so as to ensure that the electronic device always operates on the antenna with better performance, thereby ensuring the communication performance of the electronic device.
In a case where it is detected that an antenna performing communication among the M antennas is a first antenna (the first antenna may be a main antenna), a first usage scenario in which the electronic device is located may be identified. Whether the antenna performing communication among the M antennas is the first antenna may be detected by an existing or new detection method, which is not specifically limited herein.
The antenna performing communication among the M antennas may be defined as a first antenna, or a main antenna among the M antennas may be defined as the first antenna, and whether the antenna performing communication among the M antennas is the first antenna may be detected by setting a communication identifier.
In an alternative embodiment, the antenna for which the communication is identified with a value of 1 may be determined as the first antenna.
In another alternative embodiment, if a main antenna of the M antennas is defined as a first antenna, and when a communication identifier of the main antenna is a value 1 and communication identifiers of other antennas are 0, it may be determined that an antenna of the M antennas performing communication is the first antenna, and when the communication identifier of the main antenna is 0 and the communication identifier of one antenna of the other antennas is 1, it may be determined that the antenna of the M antennas performing communication is not the first antenna.
The first usage scenario in which the electronic device is located may refer to: in the case that the antenna for performing communication among the M antennas is the first antenna, a user may use the electronic device in a usage scenario, that is, in the case that the antenna for performing communication among the M antennas is the first antenna, the usage scenario in which the electronic device is located includes, but is not limited to, preset usage scenarios such as one-hand holding, two-hand holding, head-hand effect, body shielding, and the like.
One-handed holding may refer to a user using the electronic device with one hand, two-handed holding may refer to a user using the electronic device with two hands in a "stick" manner, a head-hand effect may refer to a situation in which the head and hands of the user are close to the earpiece of the electronic device when the user uses the electronic device, such as a use scenario when the user uses the electronic device to make a call, which is a head-hand effect, and body shielding may refer to a situation in which the electronic device is placed in a shielding position when the user uses the electronic device, such as a pocket (jacket pocket or pants pocket, etc.) similar to the electronic device.
The identification method of the usage scenario in which the electronic device is located may be multiple, for example, one or more sensors in the electronic device may be used to identify the usage scenario in which the electronic device is located, and when the multiple sensors of the electronic device are used to identify the usage scenario in which the electronic device is located, the multiple sensors may be the same sensor or different sensors, and are not specifically limited herein.
The plurality of sensors may include, but are not limited to, a proximity sensor, an infrared sensor, and the like, and for a single-handed usage scene and a two-handed usage scene, the two proximity sensors may be respectively disposed on an upper portion and a lower portion of the electronic device for identification, and in a case where the proximity sensor disposed on the lower portion detects an object approaching, the usage scene where the electronic device is located may be identified as a single-handed usage scene, and in a case where the proximity sensors disposed on the upper portion and the lower portion both detect an object approaching, the usage scene where the electronic device is located may be identified as a two-handed usage scene, to name a few examples.
For the use scene of the head-hand effect, the distance between the electronic device and the brain can be detected through a near-distance sensor or an infrared sensor arranged near the earphone, so that when the brain is close to the electronic device, the use scene where the electronic device is located is identified as the head-hand effect.
Aiming at the use scene sheltered from by the body, the distance between the electronic equipment and each part of the body can be detected through the proximity sensor and the infrared sensor, and under the condition that the proximity sensor detects that the electronic equipment is far away from the hand of the user and the infrared sensor detects that the electronic equipment is close to the part of the body of the user, the use scene where the electronic equipment is located is identified as the body shelter.
The headset in the electronic device may also be used to identify a usage scenario of the head-hand effect, for example, in a case that the headset is detected to be in a usage state, the usage scenario where the electronic device is located may be identified as the head-hand effect.
The usage scenario in which the electronic device is located can also be identified based on the information input by the user by receiving the information input by the user. The information input by the user can be related information which characterizes the current use scene of the electronic equipment.
In this step, under the influence of factors such as actual antenna architecture, wiring mode, material selection, actual use scene, and antenna inherent performance, there will be a certain radiation performance difference between different antennas.
The radiation performance may be represented by a Total Radiated Power (TRP) index and a Total Isotropic reception Sensitivity (TIS) index, the TPR may reflect a reception Sensitivity condition of the entire radiation spherical electronic device, and the TIS may reflect an emission Power condition of the whole device.
The radiation performance difference between different antennas may include a first radiation performance difference, where the first radiation performance difference refers to a radiation performance difference between different antennas caused by the influence of factors such as an actual antenna architecture, a routing manner, material selection, and an actual usage scenario. The specific reason for this is that under the influence of factors such as an actual antenna architecture, a routing manner, material selection, and an actual usage scenario, a certain imbalance may exist between different antennas (including between a main antenna and an auxiliary antenna), and a quantified value of this imbalance may be referred to as an imbalance threshold, which may represent a first radiation performance difference between a first antenna and another antenna.
In addition, under the influence of different usage scenarios, due to differences in antenna shielding and surrounding environments, imbalance thresholds of the first antenna and other antennas in the M antennas in different usage scenarios may be different, that is, differences in first radiation performance of the first antenna and the other antennas in different usage scenarios may be different. Therefore, the imbalance threshold corresponding to the current use scene of the electronic device can be obtained, and the imbalance threshold is used as the basis for antenna switching.
The imbalance threshold corresponding to the current usage scenario of the electronic device may be queried in a preset register, the imbalance threshold under different usage scenarios may be stored in the preset register in a table form, and the imbalance thresholds may be tested in advance and stored in the preset register.
Specifically, the following method may be adopted to obtain the corresponding imbalance threshold values in different usage scenarios.
Data collection, for each antenna in an electronic device, when the antenna performs communication, a simulation test can be performed in a darkroom by using scenes (such as single-hand grip, double-hand grip, body occlusion, and head-hand effect) separately, and imbalance thresholds between the antenna and other antennas when the TRP and TIS of the antenna performing communication are optimized are obtained, as shown in table 1.
Table 1 corresponding imbalance thresholds for different usage scenarios for each antenna
| Usage scenarios | Threshold value of unbalance |
| Single hand holding | A |
| Double-hand grip | B |
| Body shield | C |
| Head-hand effect | D |
Storing the imbalance threshold corresponding to each antenna in different use scenes in a preset register in a table form, so that the corresponding imbalance threshold can be selected subsequently according to the actual use scene of the electronic equipment.
Specifically, the imbalance threshold values corresponding to the first antenna in different usage scenarios may be obtained, and then the imbalance threshold value corresponding to the first usage scenario is obtained from the imbalance threshold values corresponding to the first antenna in different usage scenarios.
And 103, switching the first antenna to the antennas of the other antennas for communication based on the imbalance threshold.
In this step, an imbalance threshold may be used as a basis for antenna switching in the usage scenario, in an optional implementation manner, the imbalance threshold may be used as a threshold of a difference in radiation performance between the first antenna and another antenna, and when a second antenna exists in the another antenna, the first antenna may be switched to the second antenna for communication, where a first difference between a received signal strength of the second antenna and a received signal strength of the first antenna is greater than the imbalance threshold.
In another alternative embodiment, there may be an inherent difference in radiation performance between different antennas (including between the primary antenna and the secondary antenna) under the influence of factors such as the inherent performance of the antennas, and this inherent difference in radiation performance may be characterized by a base threshold, which is used to characterize a second difference in radiation performance between the first antenna and the other antenna, and the sum of the imbalance threshold and the base threshold is used to characterize the overall difference in radiation performance between the first antenna and the other antenna.
The sum of the imbalance threshold and the base threshold may be used as a threshold for a difference in radiation performance between the first antenna and another antenna, and in the case where a second antenna exists among the other antennas, the first antenna may be switched to the second antenna for communication, and a first difference between the received signal strength of the second antenna and the received signal strength of the first antenna is greater than the sum of the imbalance threshold and the base threshold.
In addition, when the second antenna is not present in the other antennas, the antenna switching may not be performed, or when the received signal strength of the first antenna is smaller than a certain threshold value, that is, when the radiation performance of the first antenna is relatively poor, the first antenna may be switched to a third antenna among the other antennas for communication, the third antenna being an antenna having a largest first difference between the received signal strength of the other antennas and the received signal strength of the first antenna.
In this embodiment, M antennas are arranged in an electronic device, and a first usage scenario in which the electronic device is located is identified when an antenna for performing communication among the M antennas is a first antenna; acquiring an imbalance threshold corresponding to the first usage scenario, where the imbalance threshold is used to characterize a first radiation performance difference between the first antenna and other antennas in the M antennas in the first usage scenario; switching the first antenna to an antenna of the other antennas for communication based on the imbalance threshold. Therefore, the antenna switching method and the antenna switching device can provide antenna switching more suitable for actual use scenes of users, so that the antenna switching is more reasonable, more flexible, more accurate and more reliable, and the antenna switching effect can be improved.
Optionally, the step 103 specifically includes:
determining a radiation performance difference threshold value of the first antenna and the other antennas based on the imbalance threshold value and a preset basic threshold value, wherein the basic threshold value is used for representing a second radiation performance difference of the first antenna and the other antennas;
and under the condition that at least one second antenna exists in the other antennas, switching the first antenna to any one of the second antennas for communication, wherein a first difference value between the received signal strength of the second antenna and the received signal strength of the first antenna is larger than the radiation performance difference threshold value.
In this embodiment, under the influence of factors such as the antenna inherent performance, there is usually an inherent radiation performance difference between different antennas (including between the main antenna and the auxiliary antenna), and the inherent radiation performance difference can be characterized by a basic threshold.
The preset basic threshold may be a basic threshold corresponding to the first antenna, and is used to characterize a second radiation performance difference between the first antenna and the other antennas.
A sum obtained by adding an imbalance threshold and a preset basic threshold may be determined as a radiation performance difference threshold between the first antenna and the other antennas, and when at least one second antenna exists in the other antennas, the first antenna is switched to any one of the second antennas for communication, where a first difference between a received signal strength of the second antenna and a received signal strength of the first antenna is greater than the radiation performance difference threshold.
In this embodiment, the radiation performance difference threshold between the first antenna and the other antennas is determined based on the imbalance threshold and a preset basic threshold; and under the condition that at least one second antenna exists in the other antennas, switching the first antenna to any one of the second antennas for communication, wherein a first difference value between the received signal strength of the second antenna and the received signal strength of the first antenna is larger than the radiation performance difference threshold value. Therefore, the antenna for current communication can be switched to the second antenna with better received signal strength, so that the electronic equipment can be ensured to communicate under the better received signal strength all the time.
Optionally, when at least one second antenna exists in the M antennas, switching the first antenna to any one of the second antennas for communication includes:
determining a first target antenna under the condition that at least one second antenna exists in the other antennas, wherein the first target antenna is the second antenna with the largest first difference value;
and switching the first antenna to the first target antenna for communication.
In this embodiment, the antenna switching determination condition may be:
Thre+Imb<max{RSRP1-RSRP0|…|RSRPi-RSRP0|…|RSRPn-RSRP0}。
wherein, Thre is a basic threshold value, Imb is an imbalance threshold value corresponding to the current use scene of the electronic device, RSRP0Is the received signal strength, RSRP, of the first antennaiIs the received signal strength of the ith antenna among the other antennas, and n is the number of the other antennas.
That is, when the difference between the received signal strength of at least one second antenna and the received signal strength of the first antenna is greater than the sum of the base threshold and the imbalance threshold among the other antennas, the second antenna with the largest difference between the received signal strength of the at least one second antenna and the received signal strength of the first antenna is determined as the first target antenna, and the first antenna is switched to perform communication.
In this embodiment, when at least one second antenna exists in the other antennas, a first target antenna is determined, where the first target antenna is the second antenna with the largest first difference; and switching the first antenna to the first target antenna for communication. In this way, the antenna currently communicating with can be switched to the second antenna with the best received signal strength, so as to ensure that the electronic device always communicates with the antenna with the best received signal strength.
Optionally, in a case that the first antenna is a main antenna, after the first antenna is switched to any one of the second antennas for communication, the method further includes:
detecting a second difference value between the received signal strength of the first antenna and the received signal strength of the second antenna under the condition that the use scene where the electronic equipment is located is identified not to be a preset use scene;
and switching the second antenna to the first antenna for communication under the condition that the second difference value is greater than a first preset threshold value, wherein the first preset threshold value is smaller than the radiation performance difference threshold value.
In this embodiment, the main antenna is usually the antenna with the best radiation performance in the electronic device, and in order to ensure that the electronic device can always maintain the antenna with the best radiation performance for communication, the antenna may be switched back, that is, the auxiliary antenna for current communication is switched to the main antenna.
Specifically, when it is recognized that the usage scenario in which the electronic device is located is not a preset usage scenario, the received signal strength of the first antenna and the received signal strength of the currently communicating second antenna may be detected in real time, or at preset time intervals, or at irregular times, so as to determine a second difference between the received signal strength of the first antenna and the received signal strength of the second antenna. The preset usage scenarios may include one-hand holding, two-hand holding, head-hand effect, body shielding, and the like, and these usage scenarios generally affect the radiation performance of the antenna.
That is to say, when the usage scenario in which the electronic device is located is not a usage scenario that affects the radiation performance of the antenna, the second antenna may be switched to the first antenna for communication if the second difference is greater than a first preset threshold, where the first preset threshold is smaller than the radiation performance difference threshold. Therefore, the auxiliary antenna for current communication can be switched back to the main antenna as soon as possible, and the electronic equipment is ensured to always communicate on the antenna with the best radiation performance.
Optionally, after the switching the first antenna to any one of the second antennas for communication, the method further includes:
detecting a third difference value between the received signal strength of a second target antenna and the received signal strength of the second antenna for communication when the situation that the usage scene of the electronic device is switched from the first usage scene to a second usage scene is identified, wherein the second target antenna is the other antenna except the second antenna for communication in the M antennas;
and switching the second antenna to the second target antenna with the maximum third difference value for communication under the condition that the third difference value is greater than a second preset threshold value, wherein the second preset threshold value is greater than 0.
In this embodiment, the second usage scenario may be a preset usage scenario such as a single-handed usage scenario, a double-handed usage scenario, a head-hand effect, or a body shielding scenario, or may be other usage scenarios, which are not specifically limited herein, and the second usage scenario is different from the first usage scenario.
When the usage scene switching of the electronic equipment is identified, the difference of the received signal strength of the other antenna and the second antenna for communication can be detected. When a second target antenna with better received signal strength than the second antenna exists in other antennas, the second antenna can be switched to the second target antenna with the best received signal strength for communication. The second preset threshold value can be set according to actual conditions, and in order to guarantee significance of antenna switching, the value of the second preset threshold value can be reasonably increased, so that the received signal strength of the second target antenna is properly better than or far better than that of the second antenna.
In this embodiment, when it is recognized that the usage scenario in which the electronic device is located is switched from the first usage scenario to a second usage scenario, a third difference between the received signal strength of a second target antenna and the received signal strength of the second antenna performing communication is detected, where the second target antenna is an antenna other than the second antenna performing communication among the M antennas; and switching the second antenna to the second target antenna with the maximum third difference value for communication under the condition that the third difference value is greater than a second preset threshold value, wherein the second preset threshold value is greater than 0. Therefore, the electronic equipment can always communicate on the antenna with the optimal received signal strength through multiple times of antenna switching.
Optionally, the step 101 specifically includes:
a first usage scenario in which the electronic device is located is identified with a sensor in the electronic device.
In this embodiment, the usage scenario in which the electronic device is located may be identified by using one or more sensors in the electronic device, and when the usage scenario in which the electronic device is located is identified by using a plurality of sensors in the electronic device, the plurality of sensors may be the same sensor or different sensors, and are not particularly limited herein.
The plurality of sensors may include, but are not limited to, a proximity sensor, an infrared sensor, and the like, and for a single-handed usage scene and a two-handed usage scene, the two proximity sensors may be respectively disposed on an upper portion and a lower portion of the electronic device for identification, and in a case where the proximity sensor disposed on the lower portion detects an object approaching, the usage scene where the electronic device is located may be identified as a single-handed usage scene, and in a case where the proximity sensors disposed on the upper portion and the lower portion both detect an object approaching, the usage scene where the electronic device is located may be identified as a two-handed usage scene, to name a few examples.
For the use scene of the head-hand effect, the distance between the electronic device and the brain can be detected through a near-distance sensor or an infrared sensor arranged near the earphone, so that when the brain is close to the electronic device, the use scene where the electronic device is located is identified as the head-hand effect.
Aiming at the use scene sheltered from by the body, the distance between the electronic equipment and each part of the body can be detected through the proximity sensor and the infrared sensor, and under the condition that the proximity sensor detects that the electronic equipment is far away from the hand of the user and the infrared sensor detects that the electronic equipment is close to the part of the body of the user, the use scene where the electronic equipment is located is identified as the body shelter.
In this way, the use scene where the electronic equipment is located can be automatically identified by using the sensor in the electronic equipment, so that the identification of the use scene is very simple.
