A cell is an area covered by a base station or a part of a base station (sector antenna) in a cellular mobile communication system, in which area electronic equipment can reliably communicate with the base station via a radio channel. Each cell is assigned a different set of channels, thus achieving frequency reuse. The path refers to a link set passed by the information source to the information sink; the channel refers to a resource which is divided by time and frequency and can be allocated to different terminals for use; carrier means that all signals are modulated to a specific frequency and transmitted through an antenna, and this frequency is called a carrier.

When the electronic device is started or the cell is switched, new contact with the cell needs to be obtained, the synchronization with the time frequency of the cell needs to be kept, and necessary information of the cell is obtained.

The signal processing method is suitable for the scene of weak signals or signal loss coverage, and is beneficial to helping a user enhance the signals of the electronic equipment or enable the electronic equipment to acquire the signals again through the signal processing method provided by the application in the scene. The application also provides a network searching application based on the carrier direction, when the fact that the signal intensity of a signal currently received by the electronic equipment is lower than a preset threshold value is detected, the situation that the number of signal grids is displayed as zero grids and no service is displayed is included, the electronic equipment can start the network searching application, and multi-channel signals and parameter information of the multi-channel signals which can be searched by the electronic equipment at the current position are obtained through network searching and cell measurement, wherein the multi-channel signals include cell signals which can be searched by the electronic equipment but do not accord with a resident condition, and an application interface of the network searching application can display the multi-channel signals searched by the electronic equipment. After the target signal is selected from the multiple signals, the carrier direction of the target signal can be determined according to the parameter information of the target signal, so that a user is prompted to carry the electronic equipment to move towards the carrier direction of the target signal through the network searching application, and the carrier direction and the direction of the electronic equipment can be displayed in real time on an application interface to facilitate the user to calibrate.
Referring to fig. 1A, fig. 1A is a schematic flowchart of a signal processing method applied to an electronic device according to an embodiment of the present disclosure. As shown in the figure, the signal processing method includes:
s101, when the electronic equipment detects that the signal intensity of a current received signal of the electronic equipment is lower than a preset threshold value, obtaining multiple paths of signals and parameter information of the multiple paths of signals through network searching or cell measurement, wherein the multiple paths of signals comprise cell signals of the electronic equipment which do not accord with a residence condition.
The preset threshold may be preset by a user, and setting the preset threshold to make the signal strength of the current received signal lower than the preset threshold may include a case where signal display is only 0, 1, and the like, which results in low communication service quality (e.g., low call quality and unstable received information) in the terminal using process, and also include a case where the terminal signal display is out of service. The electronic device may obtain, through network searching or cell measurement, multiple channels of signals that can be searched by the current location of the electronic device, and parameter information of the multiple channels of signals, where the parameter information may include parameters such as signal strength, received power, signal stability, and the like, where the multiple channels of signals include cell signals that are searched by the electronic device and do not meet the camping condition. As shown in fig. 1B, although the electronic device 101 can search for the signal sent by the base station NB102, since the electronic device 101 loses coverage, the screen interface displays the signal as an out-of-service warning message, where S criterion is < 0.
S102, the electronic equipment selects a target signal from the multipath signals and determines the carrier direction of the target signal.
The electronic device may display the searched multipath signals and parameter information of the multipath signals through an application interface of the network searching application, and select the target signal from the multipath signals, specifically, the electronic device may select a signal with the best signal strength currently searched as the target signal by default, or a user selects the signal according to the displayed multipath signals, and after the target signal is determined, the electronic device may further determine the carrier direction of the target signal.
When determining the carrier direction of the target signal, it is assumed that the electronic device receives signals using multiple antennas, and the arrangement of the antennas is shown in fig. 1C, (a) is a reference example diagram of a dual-polarized antenna array, and (b) is a single-polarized antenna arrayReferring to the example of the column, the number of antennas for one polarization direction is NRXX represents a specific number of antennas, X in fig. 1C is 4, which is only a reference example, and the actual number of antennas X is not limited herein, and the specific number of antennas is determined by hardware parameters of the electronic device itself. If the terminal adopts a dual-polarized antenna, the actual number of receiving antennas is 2NRXThe antenna spacing is d, specifically, referring to a spacing d1 between dual-polarized antennas or a spacing d2 between single-polarized antennas in fig. 1C, if the carrier frequency of the received signal is f, the wavelength of the signal is f
And each receiving antenna is in the same amplitude and phase, taking a single-polarized antenna array as an example, at this time, d corresponds to d2, and the specific calculation process of the carrier direction is as follows:
(1) calculating channel estimation value h on each subcarrier of each receiving antenna through Single Side Band (SSB) signalnrx，kK represents the specific number of carriers, and the formula is as follows:
hnrx，k＝rnrx，k/snrx，k
r in the formulanrx，kRepresenting the value of the received signal, snrx，kRepresenting the reference signal value.
(2) Calculating a channel correlation matrix, and for the channel of the dual-polarized antenna, calculating the channel correlation matrix of each polarization direction respectively, and then superposing the channel correlation matrices of the two polarization directions to obtain a total channel correlation matrix, wherein the formula is as follows:
in the formula
Hk HIs HkThe conjugate transpose matrix of (2).
(3) Calculating the relative incoming wave direction of the signal, assuming a pre-stored AOA vector tableIs composed of
As shown in fig. 1D, which is a reference example diagram of the AOA vector, the correlation value between the AOA vector table and the channel correlation matrix is calculated:
corrθ＝V·R·VH
then, the maximum value AOA of the correlation value is calculated as maxθ(corrθ) And obtaining the carrier direction according to the angle value of theta corresponding to the maximum value.
S103, the electronic equipment prompts a user to move towards the carrier direction of the target signal.
After the carrier direction of the target signal is determined, the carrier direction can be displayed on an application interface of the network searching application, and a user is prompted to carry the electronic device to move towards the carrier direction, so that the distance between the electronic device and the base station can be reduced, the target signal received by the electronic device is enhanced and meets the condition of cell residence, as shown in fig. 1E, it can be seen that the electronic device 101 moves towards the carrier direction of the target signal, so that S <0 is changed into S >0, so that better signal quality can be obtained, and wireless communication service can be obtained again, in addition, after the user moves to enable S >0, the user can be reminded, so that the user can select whether to close the network searching application and stop moving.
It can be seen that, in the embodiment of the present application, when detecting that the signal strength of the current received signal of the electronic device is lower than the preset threshold, the electronic device obtains multiple paths of signals and parameter information of the multiple paths of signals through network search or cell measurement, where the multiple paths of signals include cell signals that the electronic device does not conform to the residence condition, then selects a target signal from the multiple paths of signals, determines the carrier direction of the target signal, and finally prompts a user to move to the carrier direction of the target signal. The electronic equipment can acquire the multi-channel signals and select the target signals from the multi-channel signals by means of network searching and cell measurement under the condition that the signals are weak or lose coverage, and moves to the base station by moving towards the carrier direction of the target signals, so that the quality of wireless communication service is improved, and the electronic equipment is helped to reacquire the wireless communication service by moving towards the carrier direction under the condition of no service.
In one possible example, the parameter information includes a signal strength of the multipath signal; the selecting a target signal from the multipath signals comprises: selecting the signal with the maximum signal intensity in the multi-path signals as the target signal; or outputting a notification message for prompting a user to select a target signal from the multiple signals, and determining a signal corresponding to a selection operation as the target signal after receiving the selection operation of the user.
If the network searching application is set to automatically select the target signal by the electronic equipment, the electronic equipment can directly select the signal with the maximum signal intensity from the multiple channels of signals as the target signal, so that after the carrier direction of the target signal is determined, a user only needs to move a very short distance by carrying the electronic equipment, or the electronic equipment can be moved more quickly to improve the communication quality or acquire the wireless communication service again. If the network searching application is set to be the target signal of the multi-channel signal displayed on the application interface by the user, the application interface can output a notification message for prompting the user to select the target signal, and after the user sees the notification message, the user can search the target signal of the multi-channel signal selected by the electronic equipment according to the self condition, so that the mobile terminal can move according to the carrier direction of the target signal, and the communication quality of the electronic equipment can be improved.
Therefore, in this example, the target signal may be determined by the electronic device or by a user, and the user only needs to set the setting function interface of the network searching application in advance, so that the target signal may be determined in different ways in different scenes, which is beneficial to improving the diversity of target signal selection.
In one possible example, the parameter information includes a carrier direction of the multipath signal; the selecting a target signal from the multipath signals comprises: detecting whether the scene where the electronic equipment is located is a mobile scene; if so, determining a moving direction corresponding to the moving scene, and selecting a signal with a carrier direction matched with the moving direction from the multi-path signals as the target signal.
The parameter information of the multi-channel signals may further include carrier directions of the multi-channel signals, and when it is detected that the current scene of the electronic device is a moving scene, the specific detection method may be to detect a moving speed and a moving duration of the electronic device, and if it is detected that both the moving speed and the moving duration meet the judgment conditions set by the moving scene, it may be determined that the electronic device is in the moving scene.
For example, when a user is riding a vehicle such as a car, a train, or a high-speed rail, the user may not be able to freely select his/her moving direction, but the moving direction of the user may be predicted, for example, an approximate moving route of the user may be determined according to the current location, destination, and the vehicle on which the user is riding, so as to determine the optimal moving direction of the electronic device.
As can be seen, in this example, when the electronic device is in a mobile scene, the signal with the strongest signal should not be directly selected as the target signal, and in order to more accurately select the target signal, the moving direction corresponding to the mobile scene needs to be pre-determined, so as to help the electronic device to acquire the wireless communication service more quickly.
In one possible example, the parameter information includes a carrier direction of the multipath signal; the selecting a target signal from the multipath signals comprises: acquiring current position information of the electronic equipment; respectively calculating the probability of the electronic equipment moving to the carrier direction of the multipath signals according to the position information; and determining the target signal according to the probability.
The parameter information of the multi-channel signals can also include carrier directions of the multi-channel signals, an application interface of the network searching application can simultaneously display the carrier directions of the signals, after the current position information of the electronic equipment is obtained, the probability that the electronic equipment moves to the carrier directions corresponding to the multi-channel signals can be respectively calculated according to the position information, and then the signal with the maximum probability is selected as the target signal.
For example, when the user wants to go to a certain destination, a moving route of the user is determined according to the position of the parent of the electronic device and the position of the destination, if the carrier direction of the signal a and the moving route are the same, the probability that the user moves towards the carrier direction of the signal a is high, and the signal a can be selected as a target signal, so that the user can walk with less bending, and for example, according to the current position of the user, the difficulty that the user goes to the carrier direction of multiple paths of signals and moves forwards for the same linear distance is determined, if the user moves towards the carrier direction of the signal B, the number of obstacles is large, the efficiency of the linear distance advancing is low, the probability that the user moves towards the carrier direction of the signal B is low, and therefore, the signal C which can advance for a large linear distance by taking a small distance should be selected as the target signal.
Therefore, in this example, the probability that the electronic device moves in the carrier direction of the multi-channel signal can be further calculated according to the position information of the electronic device, so that the target signal is selected according to the probability, which is beneficial to ensuring that the user moves in the carrier direction of the target signal, reducing the influence on the target user, and improving the moving efficiency.
In one possible example, the method further comprises: adjusting a physical attitude of the electronic device, the adjusting being used to fix an orientation of the electronic device antenna; prompting a user to maintain a current physical pose of the electronic device.
The physical attitude of the electronic device needs to be adjusted, and the adjustment is mainly used for determining the orientation of the antenna, fixing the orientation of the antenna, prompting a user to keep the current physical attitude of the electronic device moving, and avoiding errors caused by calculating the carrier direction of a target signal in real time in the electronic device.
It can be seen that, in this example, since the carrier direction of the target signal is determined in relation to the position of the antenna, the direction of the antenna needs to be fixed, and the user is prompted to hold the electronic device in the current physical posture, so that a large error in the calculated carrier direction due to a change in the direction of the antenna is avoided.
In one possible example, the method further comprises: when the change of the physical posture of the electronic equipment is detected, determining the relative position relationship between the changed physical posture and the physical posture before the change; and adjusting the calculation mode of the carrier direction of the target signal according to the relative position relationship so that the change of the physical posture does not cause the change of the calculation result of the carrier direction.
Wherein, if the physical posture of the electronic device is detected to be changed, for example, the horizontal angle or the vertical angle of the electronic device is changed, at this time, the position of the antenna changes, the angle between the antenna and the received signal also changes, since the electronic device needs to calculate the carrier direction of the target signal in real time according to the current position, therefore, it is necessary to determine the relative position relationship between the physical attitude after the change and the physical attitude before the change, and adjust the calculation mode of the target signal carrier direction according to the relative position relationship, so that the change of the physical posture of the electronic equipment can not cause the change of the calculation result of the carrier direction, that is, in the process of moving the electronic device carried by the user in the carrier direction, even if the physical posture of the electronic device changes, the displayed carrier direction does not change all the time and points to the direction of the base station all the time.
In this example, when the physical posture of the electronic device is detected to change, the calculation mode of the carrier direction of the target signal is adjusted by determining the relative position relationship between the physical posture before the change and the physical character bar after the change, so that the calculation result of the carrier direction is not changed due to the physical posture of the electronic device, and the error reduction is facilitated.
In one possible example, after determining the carrier direction of the target signal, the method further comprises: and displaying the current direction of the electronic equipment and the carrier direction of the target signal in a compass interface mode, wherein the current direction of the electronic equipment is a pointer direction, and the carrier direction of the target signal is a highlighted target direction.
The display interface of the carrier direction of the target signal can be a compass interface, the pointer points to the current orientation of the electronic equipment, the orientation of the electronic equipment can be updated in real time in the moving process of a user, and the carrier direction is highlighted on the display interface, so that the user can be helped to move towards the correct carrier direction.
Therefore, in this example, the orientation of the electronic device and the carrier direction of the target signal are displayed in the form of a compass interface, so that the user can be helped to accurately identify the carrier direction in the process of moving to the carrier direction, and the user can be helped to carry the electronic device to move to the base station direction more efficiently and accurately through visual interface display, so that the electronic device can acquire the wireless communication service again.
Referring to fig. 2, fig. 2 is a schematic flow chart of a signal processing method according to an embodiment of the present application, and the signal processing method is applied to an electronic device, consistent with the embodiment shown in fig. 1A. As shown in the figure, the signal processing method includes:
s201, when detecting that the signal intensity of a currently received signal of the electronic equipment is lower than a preset threshold value, the electronic equipment obtains multiple paths of signals and parameter information of the multiple paths of signals through network searching or cell measurement, wherein the multiple paths of signals comprise cell signals of the electronic equipment which do not accord with a residence condition.
