According to the intelligent antenna switching method provided by the embodiment of the application, an extensible outdoor antenna device is added, so that part of antennas of the indoor antenna device can be intelligently switched to the outdoor antenna device to transmit and receive wireless signals, and under any variation condition (such as damage or interference caused by a movable obstacle) of the antennas, the available antennas can be quickly awakened to switch, so that more intelligent selection among the antennas is achieved, good wireless signals are provided, and the power consumption is effectively solved.
Fig. 1 is a schematic diagram of a smart antenna switching system according to an embodiment of the present application. The smart antenna switching system 100 of the embodiment of the present application includes an InDoor communication device (IDU) 110, switching devices 121 and 123, and an OutDoor communication device (ODU) 130.IDU 110 has at least two groups of antennas, one of which is initial antenna 111 and the other of which is antenna 113 to be switched. The antenna 113 to be switched is used to switch to an OutDoor Unit (ODU) 130 by using the switching devices 121 and 123 when the quality of the wireless signal of the IDU 110 is poor, so as to improve the quality of the wireless signal. The indoor communication device 110 determines whether to switch the signal transceiving operation from the antenna to be switched 113 to the ODU 130 or from the ODU 130 to the antenna to be switched 113 according to the wireless signal quality of the initial antenna 111 and the antenna to be switched 113. Meanwhile, a Holding Period (HP) and a Comparison Period (CP) of the antenna 113 to be switched are adjusted according to whether the antenna 113 to be switched is switched.
Fig. 2 is a flowchart of steps of a smart antenna switching method according to an embodiment of the present application, which is applied to an electronic device, wherein the electronic device is an indoor communication device 110 shown in fig. 1. The order of the steps in the flow diagrams may be changed, and some steps may be omitted, according to different needs.
In step S201, radio signal parameters of the radio environment, such as received signal strength indication (Received Signal Strength Indicator, RSSI), reference signal received quality (Reference Signal Receiving Quality, RSRQ), reference signal received power (Reference Signal Receiving Power, RSRP), etc., are collected.
In step S202, it is determined whether the HP of the antenna 113 to be switched of the indoor communication device 110 is 0 (hp+=0), indicating whether to operate. The Hold Period (HP) refers to a period of time during which the antenna 113 to be switched is held in operation in a certain operation period, and the Comparison Period (CP) refers to a period of time during which the quality of the wireless signals of the initial antenna 111 and the antenna 113 to be switched are compared in the same operation period.
In the embodiment of the present application, for example, five operation phases (defined as steppe=1..5) may be defined, but not limited thereto, as follows:
first stage (stepper=1), HP value 30 seconds, CP value 1 minute;
second stage (stepper=2), HP value of 1 min, CP value of 40 seconds;
third stage (stepper=3), HP value 10 minutes, CP value 30 seconds;
fourth stage (stepper=4), HP value 30 minutes, CP value 10 seconds; and
in the fifth stage (stepper=5), the HP value remains unchanged (HP can be considered as infinite), CP may be 0 seconds or any value.
In step S203, if the HP value is 0, the period of time for which the antenna 113 to be switched maintains operating in the current operating stage is ended, the quality of the wireless signals of the initial antenna 111 and the antenna 113 to be switched is compared in the current operating stage according to the wireless signal parameters, and whether the CP value in the current operating stage is 0 (cp= =0) is determined. If the CP value is not 0, the comparison operation is continued.
The operation of comparing the quality of the wireless signals of the initial antenna 111 and the antenna 113 to be switched according to the wireless signal parameters in the current operation stage is as follows:
calculating cells of the initial antenna 111 and the antenna 113 to be switched according to formula (1)Load values, e.g. cell_loading 111 With cell_loading 113 Equation 1) is as follows:
where n=12×channel_bandwidth× 5,N denotes the total number of subcarriers (subcarriers), and channel_bandwidth denotes the bandwidth.
Then, the signal fractions of the initial antenna 111 and the antenna 113 to be switched, such as Score, are calculated according to the formula (2) 111 And Score 113 Equation (2) is shown below:
Score＝RSRP+(0.73-Cell_Loading×1.67)×RSRQ......(2)
if Score 111 ＞Score 113 Indicating that the signal quality of the initial antenna 111 is better than the signal quality of the antenna 113 to be switched, and conversely, indicating that the signal quality of the initial antenna 111 is worse than the signal quality of the antenna 113 to be switched.
In step S204, if the CP value is 0, it is determined whether to switch the antenna according to the determination result of the wireless signal quality. That is, the signal transceiving operation is performed by switching the antenna 113 to be switched to the ODU 130, or by switching the ODU 130 back to the antenna 113 to be switched.
In step S205, if the antenna is not switched, the HP value is increased and the CP value is decreased by stepper+1 (stepper++). Then, returning to step S201, the wireless signal parameters of the wireless environment are continuously collected, and the above steps are repeatedly performed.
In step S206, if the antenna is switched, the antenna to be switched 113 is switched to the ODU 130 for signal transmission/reception, or the ODU 130 is switched back to the antenna to be switched 113, and the HP value is decreased and the CP value is increased. Then, returning to step S201, the wireless signal parameters of the wireless environment are continuously collected, and the above steps are repeatedly performed.
In step S207, if the HP value is not 0, it is determined whether the value of steppe is maximum (steppe= Max) in step S202.
If the value of Stepper is maximum, meaning that the HP value is infinite (hp= infinite), CP may be 0 seconds or any value. At this time, the signal transceiving operation is performed by the currently operating antenna, which may be the antenna 113 to be switched or the ODU 130. Conversely, if the value of Stepper is not the maximum, HP-1 (HP- -).
Step S208, judging whether the variation range of the wireless signal quality of the wireless network environment reaches a critical value. For example, the signal strength value of RSRP varies to reach the threshold value. If the variation range of the wireless signal quality of the wireless network environment does not reach the threshold, returning to step S201, continuously collecting the wireless signal parameters of the wireless network environment, and repeating the above steps.
Step S209, if the variation range of the wireless signal quality of the wireless network environment reaches the threshold, the HP value of the currently operating antenna is set to 0 (hp=0), and then the process returns to step S201, and the wireless signal parameters of the wireless network environment are continuously collected, and the above steps are repeatedly executed.

Fig. 4 is a functional block diagram of an electronic device for performing a smart antenna switching method according to an embodiment of the present application. The smart antenna switching method according to the embodiments of the present application may be implemented by a computer program in a storage medium, for example, the memory 220 in the electronic device 200. When a computer program implementing the method of the present application is loaded into the memory 220 by the processor 210, the processor 210 of the line apparatus 200 is driven to execute the smart antenna switching method of the embodiment of the present application.
The electronic device 200 of the embodiment of the application includes a data obtaining module 310, a judging module 320 and a processing module 330.
The data acquisition module 310 collects wireless signal parameters of the wireless environment, such as Received Signal Strength Indication (RSSI), reference Signal Received Quality (RSRQ), reference Signal Received Power (RSRP), and so on.
The determining module 320 determines whether the Hold Period (HP) of the antenna 113 to be switched of the indoor communication device 110 is 0 (hp+=0). The Hold Period (HP) refers to a period of time during which the antenna 113 to be switched is held in operation in a certain operation period, and the Comparison Period (CP) refers to a period of time during which the quality of the wireless signals of the initial antenna 111 and the antenna 113 to be switched are compared in the same operation period.
In the embodiment of the present application, for example, five operation phases (defined as steppe=1..5) may be defined, but not limited thereto, as follows:
first stage (stepper=1), HP value 30 seconds, CP value 1 minute;
second stage (stepper=2), HP value of 1 min, CP value of 40 seconds;
third stage (stepper=3), HP value 10 minutes, CP value 30 seconds;
fourth stage (stepper=4), HP value 30 minutes, CP value 10 seconds; and
in the fifth stage (stepper=5), the HP value remains unchanged (HP can be considered as infinite), CP may be 0 seconds or any value.
If the HP value is 0, which indicates that the period of time for which the antenna 113 to be switched maintains operating in the current operating phase is over, the determining module 320 compares the wireless signal quality of the initial antenna 111 and the wireless signal quality of the antenna 113 to be switched in the current operating phase, and determines whether the CP value in the current operating phase is 0 (cp= 0). If the CP value is not 0, the comparison operation is continued.
The operation of comparing the quality of the wireless signals of the initial antenna 111 and the antenna 113 to be switched according to the wireless signal parameters in the current operation stage is as follows:
cell Loading values of the initial antenna 111 and the antenna 113 to be switched, for example, cell_loading, are calculated according to formula (1) 111 With cell_loading 113 Equation (1) is shown below:
where n=12×channel_bandwidth× 5,N denotes the total number of subcarriers (subcarriers), and channel_bandwidth denotes the bandwidth.
Then, the signal fractions of the initial antenna 111 and the antenna 113 to be switched, such as Score, are calculated according to the formula (2) 111 And Score 113 Equation (2) is shown below:
Score＝RSRP+(0.73-Cell_Loading×1.67)×RSRQ......(2)
and
If Score 111 ＞Score 113 Indicating that the signal quality of the initial antenna 111 is better than the signal quality of the antenna 113 to be switched, and conversely, indicating that the signal quality of the initial antenna 111 is worse than the signal quality of the antenna 113 to be switched.
If the CP value is 0, the determining module 320 determines whether to switch the antenna according to the determination result of the wireless signal quality. That is, the signal transceiving operation is performed by switching the antenna 113 to be switched to the ODU 130, or by switching the ODU 130 back to the antenna 113 to be switched.
If the antenna is not switched, the processing module 330 will steppe+1 (steppe++), at which time the HP value will increase and the CP value will decrease. Then, the data obtaining module 310 continues to collect the wireless signal parameters of the wireless environment, and repeatedly performs the above steps.
If the antenna is switched, the processing module 330 will step-1 (step- -), where the HP value will decrease and the CP value will increase. Then, the data obtaining module 310 continues to collect the wireless signal parameters of the wireless environment, and repeatedly performs the above steps.
If the HP value is not 0, the determination module 320 determines whether the value of steppe is maximum (steppe= Max).
If the value of Stepper is maximum, the processing module 330 sets the HP value to infinity (hp= infinite), the CP value may be 0 seconds or any value. At this time, the signal transceiving operation is performed by the currently operating antenna, which may be the antenna 113 to be switched or the ODU 130. Conversely, if the value of Stepper is not the maximum, the processing module 330 will HP-1 (HP- -).
The determining module 320 determines whether the variation range of the wireless signal quality of the wireless network environment reaches the threshold. For example, the signal strength value of RSRP varies to reach the threshold value. If the variation range of the wireless signal quality of the wireless network environment does not reach the threshold, the data acquisition module 310 continues to collect the wireless signal parameters of the wireless network environment, and the above steps are repeatedly performed.
If the variation range of the wireless signal quality of the wireless network environment reaches the threshold, the processing module 330 sets the HP value of the currently operating antenna to 0 (hp=0), and then the data acquisition module 310 continues to collect the wireless signal parameters of the wireless network environment, and repeats the above steps.
It will be appreciated that the above described division of modules is merely a logical division of functions and that other divisions of implementation are possible. In addition, each functional module in the embodiments of the present application may be integrated in the same processing unit, or each module may exist alone physically, or two or more modules may be integrated in the same unit. The integrated modules may be implemented in hardware or in hardware plus software functional modules.
Other corresponding changes and modifications can be made by those skilled in the art in light of the practical needs generated by combining the technical scheme and the technical conception provided by the embodiment of the present application, and all such changes and modifications are intended to fall within the scope of the claims of the present application.
