Abstract

A smart antenna switching method is disclosed. Multiple wireless signal parameters of a wireless environment are collected. Under a current processing stepper, when a holding period of a to-be-switched antenna is 0, the qualities of wireless signals between an original antenna and the to-be-switched antenna are compared according to the wireless signal parameters. When a comparing period of the to-be-switched antenna is 0, it is determined whether an antenna switching operation is performed. If the antenna switching operation is not performed, the next processing stepper is served as the current processing stepper. If the antenna switching operation is performed, a signal receiving-and-sending operating is switched from the to-be-switched antenna to the outdoor antenna or from the outdoor antenna to the to-be-switched antenna, and the previous processing stepper is served as the current processing stepper.

FIG. 1 is a schematic diagram of a smart antenna switching system according to an embodiment of the present invention. The smart antenna switching system 100 of the embodiment of the present invention includes an indoor communication device (InDoor Unit, IDU) 110 , switching devices 121 and 123 , and an outdoor communication device (Outdoor Unit, ODU) 130 . The IDU 110 has at least two groups of antennas, one group is the initial antenna 111 and the other group is the antenna 113 to be switched. The antenna to be switched 113 is used to switch to the outdoor communication device (Outdoor Unit, ODU) 130 by switching devices 121 and 123 when the wireless signal quality of the IDU 110 is not good, so as to improve the wireless signal quality. The indoor communication device 110 determines whether to switch the signal transmitting and receiving operation from the antenna 113 to be switched to the ODU 130 or to switch back to the antenna 113 to be switched by the ODU 130 according to the wireless signal quality of the initial antenna 111 and the antenna to be switched 113 . Meanwhile, the holding period (Holding Period, HP) and the comparison period (Comparing 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 flow chart of steps of a smart antenna switching method according to an embodiment of the present invention, which is applied in a microcontroller of an electronic device, and the electronic device is the indoor communication device 110 shown in FIG. 1 . According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.

Step S201, collecting wireless signal parameters of the wireless environment, for example, Received Signal Strength Indicator (RSSI), Reference Signal Receiving Quality (Reference Signal Receiving Quality, RSRQ), Reference Signal Received Power (Reference Signal Receiving Power, RSRP )etc.

Step S202 , judging whether the HP of the antenna 113 to be switched of the indoor communication device 110 is 0 (HP == 0), indicating whether it is in operation. The maintenance period (HP) refers to the cycle time during which the antenna 113 to be switched maintains operation in a certain operation stage, and the comparison period (CP) refers to the comparison of the wireless signals of the initial antenna 111 and the antenna 113 to be switched in the same operation stage The cycle time of good and bad quality.

In the embodiment of the present invention, for example, five operation stages (defined as Stepper=1..5) can be defined, but not limited thereto, as follows:

In the first stage (Stepper=1), the HP value is 30 seconds, and the CP value is 1 minute;

In the second stage (Stepper=2), the HP value is 1 minute, and the CP value is 40 seconds;

In the third stage (Stepper=3), the HP value is 10 minutes, and the CP value is 30 seconds;

In the fourth stage (Stepper=4), the HP value is 30 minutes, and the CP value is 10 seconds; and

In the fifth stage (Stepper=5), the HP value remains unchanged (HP can be regarded as infinite), and the CP may be 0 seconds or any value.

Step S203, if the HP value is 0, it means that the cycle time for the antenna 113 to be switched to maintain operation in the current operation stage has ended, then in the current operation stage, according to the wireless signal parameters, compare the wireless signals of the initial antenna 111 and the antenna 113 to be switched. The signal quality is good or bad, and judge whether the CP value in the current operation stage is 0 (CP == 0). If the CP value is not 0, continue the comparison operation.

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 to say, the signal transceiving operation is performed by switching from the antenna 113 to be switched to the ODU 130 , or by switching the ODU 130 back to the antenna 113 to be switched to be performed.

Step S205, if the antenna is not switched, set Stepper+1 (Stepper++), at this time, the HP value will increase, and the CP value will decrease. Next, return to step S201, continue to collect wireless signal parameters of the wireless environment, and repeat the aforementioned steps.

Step S206, if the antenna is switched, Stepper-1 (Stepper --) is used to switch the signal sending and receiving operation from the antenna 113 to be switched to the ODU 130, or switch the ODU 130 back to the antenna 113 to be switched, and the HP value will decrease, and the CP value will increase. Next, return to step S201, continue to collect wireless signal parameters of the wireless environment, and repeat the aforementioned steps.

In step S207, in step S202, if the HP value is not 0, it is determined whether the value of Stepper is the maximum (Stepper == Max).

If the value of Stepper is the maximum, the HP value is infinite (HP == infinite), and the CP may be 0 seconds or any value. At this time, the signal transceiving operation will be 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, set 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 variation range of the signal strength value of RSRP reaches the threshold value. If the fluctuation range of the wireless signal quality of the wireless network environment does not reach the critical value, go back to step S201, continue to collect the wireless signal parameters of the wireless environment, and repeat the aforementioned steps.

Step S209, if the fluctuation range of the wireless signal quality of the wireless network environment reaches the critical value, set the HP value of the currently operating antenna to 0 (HP = 0), and then return to step S201 to continue collecting the wireless The wireless signal parameters of the environment, repeat the above steps.

FIG. 4 is a functional block diagram of an electronic device according to an embodiment of the present invention, which is used for implementing a smart antenna switching method. The smart antenna switching method of the embodiment of the present invention can be implemented by a computer program in a storage medium, for example, the memory 220 in the electronic device 200 . When the computer program implementing the method of the present invention is loaded into the memory 220 by the processor 210, the processor 210 of the electronic device 200 is driven to execute the smart antenna switching method of the embodiment of the present invention.

The electronic device 200 of the embodiment of the present invention, for example, a smart antenna device, 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 Indicator (RSSI), Reference Signal Received Quality (RSRQ), Reference Signal Received Power (RSRP) and so on.

The judging module 320 judges whether the maintenance period (HP) of the antenna 113 to be switched of the indoor communication device 110 is 0 (HP==0). The maintenance period (HP) refers to the cycle time during which the antenna 113 to be switched maintains operation in a certain operation stage, and the comparison period (CP) refers to the comparison of the wireless signals of the initial antenna 111 and the antenna 113 to be switched in the same operation stage The cycle time of good and bad quality.

In the embodiment of the present invention, for example, five operation stages (defined as Stepper=1..5) can be defined, but not limited thereto, as follows:

In the first stage (Stepper=1), the HP value is 30 seconds, and the CP value is 1 minute;

In the second stage (Stepper=2), the HP value is 1 minute, and the CP value is 40 seconds;

In the third stage (Stepper=3), the HP value is 10 minutes, and the CP value is 30 seconds;

In the fourth stage (Stepper=4), the HP value is 30 minutes, and the CP value is 10 seconds; and

In the fifth stage (Stepper=5), the HP value remains unchanged (HP can be regarded as infinite), and the CP may be 0 seconds or any value.

If the HP value is 0, it means that the cycle time for the antenna 113 to be switched to maintain operation in the current operation stage has ended, and then the judging module 320 compares the wireless signal quality of the initial antenna 111 and the antenna 113 to be switched in the current operation stage. And judge whether the CP value in the current operation stage is 0 (CP == 0). If the CP value is not 0, continue the comparison operation.

If the CP value is 0, the judging module 320 judges whether to switch the antenna according to the judging result of the wireless signal quality. That is to say, the signal transceiving operation is performed by switching from the antenna 113 to be switched to the ODU 130 , or by switching the ODU 130 back to the antenna 113 to be switched to be performed.

If the antenna is not switched, the processing module 330 will set Stepper+1 (Stepper++), at this time, the HP value will increase, and the CP value will decrease. Then, the data acquisition module 310 continues to collect the wireless signal parameters of the wireless environment, and repeats the aforementioned steps.

If the antenna is switched, the processing module 330 will be Stepper-1 (Stepper--), at this time, the HP value will decrease, and the CP value will increase. Then, the data acquisition module 310 continues to collect the wireless signal parameters of the wireless environment, and repeats the aforementioned steps.

If the HP value is not 0, the judging module 320 judges whether the value of Stepper is the maximum (Stepper == Max).

If the value of Stepper is the maximum, the processing module 330 sets the HP value to be infinite (HP == infinite), and the CP value may be 0 seconds or any value. At this time, the signal transceiving operation will be performed by the currently operating antenna, which may be the antenna 113 to be switched or the ODU 130 . On the contrary, if the value of Stepper is not the maximum, the processing module 330 will set HP-1 (HP --).

The judging module 320 judges whether the fluctuation range of the wireless signal quality of the wireless network environment reaches the critical value. For example, the variation range of the signal strength value of RSRP reaches the threshold value. If the fluctuation range of the wireless signal quality of the wireless network environment does not reach the critical value, the data acquisition module 310 continues to collect the wireless signal parameters of the wireless environment, and repeats the aforementioned steps.

If the variation range of the wireless signal quality of the wireless network environment reaches the critical value, 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 For the wireless signal parameters of the wireless environment, repeat the preceding steps.
