Detailed Description
The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The method for switching the antenna provided by the embodiment of the application is described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
With the development of technology, at present, electronic devices (such as 5G mobile phone terminals) may integrate multiple antennas, and when designing antennas, a certain imbalance exists between different antennas due to the influence of actual antenna architecture, routing mode, material selection, and the like, and this imbalance is called an imbalance threshold (Imbalance Threshold). In practical application, different machine types have different unbalanced thresholds due to different demands, and the same machine type has different unbalanced thresholds due to the influence of an integration process. In the situations of cell edge or dead holding, the receiving signal of the antenna is weakened, and the quality of the receiving signal is ensured by adopting a mode of switching the antenna, wherein the dead holding refers to the situation that the receiving signal of the electronic equipment is weakened due to shielding of the palm when the palm contacts with the external antenna of the electronic equipment. In switching antennas, the imbalance threshold of the antenna is an important factor affecting the received signal strength of the antenna after switching. Since the imbalance threshold is often set to a fixed value in the electronic device at present, however, according to the fixed imbalance threshold, the electronic device cannot ensure that the switching antenna can receive the electromagnetic wave signal with higher signal strength. In order to solve the above technical problems, as shown in fig. 1, an embodiment of the present application provides a method for switching antennas. The method may include steps 101 to 103 described below. The method will be exemplarily described below taking an apparatus in which an execution body is a switching antenna as an example.
Step 101: the device for switching the antennas obtains a first signal strength of the first antenna and a second signal strength of the second antenna.
In the embodiment of the application, in the using process of the electronic equipment, both antennas can receive electromagnetic wave signals, and the signal intensity can be detected through the received electromagnetic wave signals.
In the embodiment of the present application, the first antenna is a current receiving antenna. The electronic device uses only the electromagnetic wave signal received by the first antenna (i.e., the current receiving antenna) as the communication signal at the same time.
Optionally, in the embodiment of the present application, the device for switching the antenna acquires the first signal strength and the second signal strength of the electronic device when detecting that the electronic device is in an abnormal environment such as a cell edge or a dead grip.
It can be understood that the electronic device is provided with the main receiving antenna (first antenna) and the auxiliary receiving antenna (second antenna), and in a normal environment, the main receiving antenna is enough to meet the communication requirement of the electronic device, without considering to switch the antennas, and in an abnormal environment of a cell edge or death, the main receiving antenna may not meet the communication requirement of the electronic device due to the limitation of the communication environment, so that it is necessary to determine whether the auxiliary receiving antenna can replace the main receiving antenna to receive signals.
Step 102: and the device for switching the antenna acquires a target unbalance threshold corresponding to the current use scene according to the unbalance threshold storage table.
In the embodiment of the application, the target unbalance threshold corresponds to the communication requirement of the current use scene, for example, the current use scene is an online video watching mode, the communication requirement corresponding to the online video watching mode focuses on throughput, the current use scene is a voice call, and the communication requirement corresponding to the voice call focuses on reliability.
In the embodiment of the application, different target imbalance thresholds are adopted, which can influence the throughput, the block error rate and the uplink power of the electromagnetic wave signals received after the antenna is switched, so that the device for switching the antenna needs to acquire the target imbalance threshold corresponding to the current use scene, so that the electromagnetic wave signals received by the antenna after switching meet the requirements of the current use scene on the communication quality.
Step 103: the device for switching the antennas switches the first antenna to the second antenna under the condition that the first signal strength, the second signal strength and the target imbalance threshold meet preset switching conditions.
In the embodiment of the application, the preset switching conditions include: the sum of the target unbalance threshold and the base threshold is smaller than the target difference; wherein, the target difference is: the difference between the first signal strength and the second signal strength. It should be understood that the base threshold refers to the lowest imbalance threshold between different antennas. The sum of the basic threshold and the target unbalance threshold is used as a comparison basis of preset switching conditions, so that the size of the target unbalance threshold and the data value of the corresponding unbalance threshold is reduced, and the calculated amount is reduced.
In the embodiment of the application, when the first antenna cannot meet the signal receiving requirement or the second antenna signal meets the requirement more than the signal received by the first antenna, whether the preset switching condition is met or not needs to be judged so that the electronic equipment can acquire the optimal receiving signal.
In the embodiment of the application, under the condition that the preset switching condition is met, the antenna switching device sends a control signal to the antenna module, and actual antenna switching operation is performed to obtain the electric signal output by the signal transmission interface corresponding to the second antenna.
In the embodiment of the application, after the device for switching the antennas switches the first antenna to the second antenna, it is further required to detect whether the electronic device is at the cell edge or in an abnormal environment such as dead grip, so that the receiving antenna is switched to the first antenna when detecting that the electronic device is not at the cell edge or in an abnormal environment such as dead grip.
In the method for switching antennas provided by the embodiment of the application, first, the first signal intensity of the first antenna and the second signal intensity of the second antenna are obtained, then, the target unbalanced threshold corresponding to the current use scene is obtained according to the unbalanced threshold storage table, and finally, the first antenna is switched to the second antenna under the condition that the first signal intensity, the second signal intensity and the target unbalanced threshold meet preset switching conditions. Therefore, the target unbalanced threshold corresponding to the current use scene is dynamically obtained, so that the switched second antenna meets the use requirement of the current use scene on the received signal, whether the preset switching condition is met or not is judged according to the target unbalanced threshold, and the switching time of the switched antenna meets the actual requirement.
Optionally, in an embodiment of the present application, as shown in fig. 2, before step 102, the method for switching antennas further includes step 201.
Step 201: the device for switching the antenna generates an imbalance threshold value storage table according to a preset training model.
In the embodiment of the application, the unbalanced threshold value storage table is used for storing an unbalanced threshold value and a parameter value of a communication attribute corresponding to the unbalanced threshold value; the communication attribute includes at least one of: throughput, block error rate, and uplink power.
In the embodiment of the application, under the current receiving environment of the electronic equipment, according to a preset training model, measuring the parameter value of the communication attribute corresponding to the unbalanced threshold value of the second antenna, and storing the unbalanced threshold value and the parameter value of the communication attribute corresponding to the unbalanced threshold value into an unbalanced threshold value storage table.
Therefore, the stored data in the unbalanced threshold value storage table is a real numerical value obtained according to the actual environment of the electronic equipment, so that the target unbalanced threshold value obtained according to the unbalanced threshold value storage table is more in line with the actual application environment, and the second antenna can receive high-quality signals for the electronic equipment.
Further alternatively, in an embodiment of the present application, as shown in fig. 3, the step 201 may be implemented through steps 301 and 302.
Step 301: the device for switching the antennas takes the second antenna as the current receiving antenna and measures the parameter value of the communication attribute corresponding to the unbalance threshold.
Step 302: the device for switching the antenna generates an imbalance threshold value storage table according to the imbalance threshold value and the parameter value of the communication attribute corresponding to the imbalance threshold value.
In the embodiment of the application, the unbalance threshold is at least one value, and the at least one value is increased from a preset initial value according to a preset step length and does not exceed a maximum value N. It should be noted that, after maintaining the preset time, each value of the imbalance threshold value, the parameter value of the communication attribute is obtained again, so as to improve the stability of the parameter value of the communication attribute.
In this way, the electronic device measures the parameter values of the communication attributes corresponding to different unbalanced thresholds under the current receiving environment, so that the generated unbalanced threshold storage table is more in line with the actual receiving situation of the second antenna, and the adaptation degree of the target unbalanced threshold obtained from the unbalanced threshold storage table and the current receiving environment can be improved.
Further alternatively, as shown in fig. 4, the step 102 may be implemented by steps 401 to 403 on the basis of generating the unbalance threshold storage table in step 201.
Step 401: the device for switching the antenna determines the target communication attribute according to the current use scene.
Step 402: the device for switching the antenna determines an optimal parameter value of the target communication attribute according to the parameter value of the target communication attribute.
Step 403: and the device for switching the antenna determines a target imbalance threshold corresponding to the optimal parameter value of the target communication attribute according to the imbalance threshold storage table.
In the embodiment of the application, the target communication attribute is any one of the communication attributes. The optimal parameter value is any one of the following: maximum throughput, minimum block error rate and minimum uplink power.
In the embodiment of the application, the current use scenes are different, and the requirements on the signal quality of the electromagnetic wave signals are different, so that the device for switching the antenna determines the target communication attribute according to the current use scenes, and the target communication attribute can be throughput, block error rate or uplink power.
In one example, the current usage scenario is an online viewing video, the communication requirement corresponding to the online viewing video is focused on throughput, and the target communication attribute corresponding to the online viewing video scenario is throughput.
In another example, the current usage scenario is a voice call, the communication requirement corresponding to the voice call is focused on reliability, and the target communication attribute corresponding to the voice call scenario is a block error rate.
In another example, the current usage scenario is a reading document, the communication requirement corresponding to the reading document is focused on power saving, and the target communication attribute corresponding to the reading document scenario is uplink power.
Therefore, according to the current use scene, the most suitable target imbalance threshold value is obtained, so that the switching time of the switching antenna is more in line with the actual demand, and the service quality of the terminal electronic equipment can be improved.
It should be noted that, in the method for switching an antenna according to the embodiment of the present application, the execution body may be an apparatus for switching an antenna, or a control module for executing the method for switching an antenna in the apparatus for switching an antenna. In the embodiment of the present application, a method for executing antenna switching by an antenna switching device is taken as an example, and the antenna switching device provided in the embodiment of the present application is described.
