Fig. 2 is a diagram of a wireless communication system 10 in accordance with an embodiment of the present invention. As shown in fig. 2, the wireless communication system 10 includes a first communication module 20, a second communication module 30 and a control module 40. The first communication module 20 may perform a first communication transmission. The second communication module 30 may perform a second communication transmission. The first communication transmission protocol and the second communication transmission protocol adopt different wireless communication technology standards, wherein the working bands used by the first communication transmission protocol and the second communication transmission protocol at least partially overlap, in other words, when the first communication transmission and the second communication transmission are carried out simultaneously, the problem of mutual interference caused by the overlapping of the working bands can be generated, but the problem can be overcome by the invention. The control module 40 can be used to control the operations of the first communication module 20 and the second communication module 30, such as, but not limited to, transmitting a control signal to enable the first communication module 20 or the second communication module 30 to perform a specific operation. The first communication module 20 is configured to actively transmit a first signal (Request) to the control module 40 when a first communication transmission is required. The control module 40 is configured to control the second communication module 30 to suspend the second communication transmission when the first signal (Request) is received (e.g., when the signal at the input of the control module 40 changes). In addition, when the second communication transmission is suspended, the control module 40 may be configured to transmit a second signal (Grant) to the first communication module 20 to enable the first communication module 20 to start the first communication transmission. It can be seen that the second communication transmission can be temporarily stopped while the first communication transmission is in progress, and thus interference between the second communication transmission and the first communication transmission can be avoided. In addition, in one embodiment, the wireless communication system 10 may also include a register 50 for storing data specific to the wireless communication system 10. In addition, in one embodiment, the wireless communication system 10 further includes a timer 60 for recording a time length of a specific operation of the wireless communication system 10.
In an embodiment, the wireless communication system 10 may be a communication device, wherein the communication device includes a first communication module 20 and a second communication module 30, for example, the wireless communication system 10 may be a smart phone, the first communication module 20 may be a ZigBee module, and the second communication module 30 may be a WiFi module, but is not limited thereto. In one embodiment, the first communication module 20 and the second communication module 30 may be various wireless communication transceivers, and at least a portion of the operating bands of the two may overlap. In one embodiment, the first communication module 20 and the second communication module 30 may each include an antenna for transmitting data. In one embodiment, the first communication module 20 and the second communication module 30 may each include a processing chip to process the respective operations, but in another embodiment, the first communication module 20 and the second communication module 30 may also use a microprocessor (CPU) on a circuit board as their own processing chips. In one embodiment, the second communication module 30 may be integrated with the control module 40; the present invention is not limited thereto.
In one embodiment, the control module 40 may be a microcontroller or microprocessor, or software or firmware in a microcontroller or microprocessor. In one embodiment, the control module 40 may be implemented by a circuit board having a processing chip and a plurality of programmable pins (GPIOs), so as to perform a specific operation according to information of the GPIO pins (pins), for example, the control module 40 may perform different operations according to different levels of a certain pin. In one embodiment, the control module 40 communicates signals with the first communication module 20 through GPIO pins. In one embodiment, the control module 40 is configured to use the first signal (Request) as an input mode (input mode) and the second signal (Grant) as an output mode (output mode), i.e. the control module 40 can generate different operations according to the first signal (Request), wherein one of the operations is to output the second signal (Grant). In addition, in an embodiment, the control module 40 may employ a packet transmission coordination (PTA) mechanism to control operations between the first communication module 20 and the second communication module 30.
In addition, in one embodiment, the register 50 may store the data that the second communication module 30 is ready to transmit when the second communication transmission is suspended, and the second communication module 30 may resume transmitting the data stored in the register 50 when the second communication transmission resumes operation, so that the second communication transmission can continue to transmit. In one embodiment, the register 50 may be implemented by a memory or other similar storage device, and is not limited thereto.
In one embodiment, the timer 60 may be used to calculate a duration of a particular operation of the wireless communication system 10, such as, but not limited to, a pause duration of the second communication transmission. With the timer 60, the wireless communication system 10 can set a default value for various operations, such as resuming the second communication transmission when the pause duration of the second communication transmission exceeds the default value, and the like, but is not limited thereto. In one embodiment, the timer 60 can be implemented by a timing circuit, in another embodiment, the timer 60 can also be a computer program, and the functions thereof can be implemented by the execution of a microprocessor, and the invention is not limited thereto.
Fig. 3 is a detailed structural diagram of the control module 40 according to an embodiment of the invention, and please refer to fig. 2. As shown in fig. 3, the control module 40 may be disposed on a Printed Circuit Board (PCB)70 and connected to a plurality of GPIO pins 72 on the printed circuit board 70. In the present embodiment, at least one GPIO pin is connected to the first communication module 20, so that the control module 40 receives the first signal (Request) from the first communication module 20. In addition, at least the pin is connected to the first communication module 20, so that the control module 40 transmits a second signal (Grant) to the first communication module 20. In addition, in an embodiment, at least one GPIO pin may serve as a communication port between the control module 40 and the second communication module 30, through which the control module 40 may transmit the third signal (Stop) to the second communication module 30, but in other embodiments, the control module 40 may be electrically connected to the second communication module 30 in other manners. For convenience of explanation, a pin receiving the first signal (Request) will be referred to as an input pin, and a pin outputting the second signal will be referred to as an output pin.
In an embodiment, when the input pin receives the first signal (Request), the voltage level of the input pin changes, for example, from a high voltage level to a low voltage level, and the control module 40 transmits a third signal to the second communication module 30, so that the second communication module 30 suspends the second communication transmission and stores the data to be transmitted by the second communication module 30 through the register 50. When the second communication transmission is suspended, the control module 40 may output a second signal (Grant) to the first communication module 20, so that the voltage level on the output pin is changed from a high voltage level to a low voltage level, and the first communication module 20 may start the first communication transmission. In addition, the timer 60 may record the length of the pause time for the second communication transmission. In one embodiment, when the voltage level on the input pin changes again, for example, from low voltage level to high voltage level, the control module 40 determines whether the length of the pause time of the second communication transmission exceeds the default value according to the record of the timer 60, thereby determining whether to stop (or pause) the first communication transmission and resuming the second communication transmission. It should be noted that, in the above embodiments, the high potential of the input pin and the output pin is used as the disable potential (disable), and the low potential is used as the enable potential (enable), but in other embodiments, the low potential may be used as the disable potential and the high potential may be used as the enable potential instead. For convenience of description, the high potential is taken as the disable potential and the low potential is taken as the enable potential for illustration.
The operation of the wireless communication system 10 will be described in detail. Fig. 4 is a flowchart of steps of a communication method according to an embodiment of the invention, which is performed by the wireless communication system 10 of fig. 2. In the present embodiment, the first communication module 20 is exemplified by a ZigBee module, the second communication module 30 is exemplified by a WiFi module, and the second communication transmission (WiFi) is in an ongoing state. First, step S41 is performed, and the wireless communication system 10 performs the first communication transmission (ZigBee), so the first communication module 20 transmits the first signal (Request) to the control module 40. Thereafter, step S42 is performed, and the control module 40 receives the first signal (Request) and transmits the third signal (Stop) to the second communication module 30. Thereafter, step S43 is executed, the second communication transmission (WiFi) operation is suspended, and the register 50 stores the data that the second communication module 30 is ready to transmit. In addition, step S44 is executed, and the timer 60 records the time length of the suspended operation of the second communication transmission (WiFi). In addition, step S45 is executed, and the control module 40 transmits a second signal (Grant) to the first communication module 20 to start the first communication transmission. Thereafter, step S46 is executed, and when the potential at the input pin changes again, the control module 40 determines whether the time for the second communication transmission (WiFi) to suspend operation has exceeded the default value. If yes, step S47 is executed, the control module 40 controls the first communication module 20 to stop the progress of the first communication transmission (ZigBee), and controls the second communication module 30 to resume the progress of the second communication transmission; if not, step S48 is executed and the control module 40 continues the first communication transmission (ZigBee). Thereby, interference between the first communication transmission (ZigBee) and the second communication transmission (WiFi) may be reduced. It should be noted that the order of the above steps is not limited, and can be changed or executed simultaneously as long as the order is reasonable.
Regarding steps S41 to S42, in an embodiment, when the control module 40 receives the first signal (Request), the input pin may change (e.g., from high to low), so the control module 40 may know that the first communication transmission (ZigBee) needs to be performed.
With respect to steps S43-S45, in an embodiment, when the second communication transmission (WiFi) is suspended, the control module 40 may set a suspension use bit (stop flag) to inform the wireless communication system 10 of the status of the second communication transmission (WiFi); wherein, when the pause use bit is 0, the second communication transmission (WiFi) is in progress, and when the pause use bit is 1, the second communication transmission (WiFi) is paused in progress; the present invention is not limited thereto.
Further, regarding steps S46 to S48, since the first communication transmission (ZigBee) may not be completed yet when the potential on the input pin changes from the low potential to the high potential, if the "whether the pause time length of the second communication transmission exceeds the default value" is used as the mechanism for assisting the determination, as long as the default value is not exceeded, the first communication transmission (ZigBee) may continue even if the potential on the input pin changes, so that the system 1 has greater adaptability. In addition, in order to avoid the efficiency reduction of the second communication transmission (WiFi) caused by the excessive progress of the first communication transmission (ZigBee), the progress of the second communication transmission (WiFi) can be timely resumed by using "whether the pause time length of the second communication transmission exceeds the default value" as the mechanism for assisting the judgment. It can be seen that, through steps S46 to S48, the efficiency of communication transmission can be improved.
In addition, in order to make the operation of the wireless communication system 10 smooth, in an embodiment, the process from the sending of the first signal (Request) to the receiving of the second signal (Grant) of the first communication module 20 corresponds to a first time period, wherein the first time period is set to be not more than 25 microseconds (μ s) (i.e. the first time period is less than or equal to 25 μ s); in another embodiment, the first time period may be between 20 to 30 microseconds, but is not limited thereto. In addition, in an embodiment, the process of "the control module 40 sends the second signal (Grant) until the wireless communication system 10 completes the Clear Channel Assessment (CCA)" corresponds to a second time length, wherein the second time length is set to be no greater than 75 microseconds (i.e., the second time length is less than or equal to 75 μ s), and in another embodiment, the second time length may be between 65 and 85 microseconds (i.e., 65 μ s is less than or equal to the second time length is less than or equal to 85 μ s), and is not limited thereto. Furthermore, in order to reduce the influence of the second communication transmission (WiFi) due to the pause, in one embodiment, the channel occupation time length of the first communication transmission (ZigBee) in every 100 milliseconds on average is set to be between 1 and 10 milliseconds (i.e. 1ms is less than or equal to 10ms), and in another embodiment, the channel occupation time length of the first communication transmission (ZigBee) in every 100 milliseconds on average is set to be between 2 and 5 milliseconds (i.e. 2ms is less than or equal to 5ms), and the method is not limited thereto.
In addition, in order to maintain the efficiency of the wireless communication system 10 when switching between the first communication transmission (ZigBee) and the second communication transmission (WiFi), the related operation settings of the control module 40 and the timer 60 are also one of the features of the present invention. In one embodiment, the timer 60 may be set to perform a prompt every specific time interval, so that the control module 40 performs the operation of "determining whether the length of the pause time of the second communication transmission (WiFi) exceeds the default value", thereby determining whether to resume the second communication transmission (WiFi). In one embodiment, the aforementioned interval-specific time may be between 10 and 30 milliseconds (i.e., 10ms ≦ interval-specific time ≦ 30 ms); in another embodiment, the specific time interval may be about 20 milliseconds, but is not limited thereto.
In another embodiment, the control module 40 may be configured to automatically turn on the second communication transmission (WiFi) and turn off the second communication transmission (WiFi) according to a specific time interval, for example, the second communication transmission (WiFi) may be automatically turned off every 80 ms, and the second communication transmission (WiFi) may be automatically turned on after about 20 ms. The above description is by way of example only and not limiting.
Fig. 5 is a schematic diagram of an experimental result according to an embodiment of the present invention, which shows a success rate of adding the first communication transmission (ZigBee) and the first communication transmission (ZigBee) in a process of transmitting with 20 to 50Mbps service traffic at a transmitting end and a receiving end of the second communication transmission (WiFi). As shown in fig. 4, the first communication transmission (ZigBee) may exhibit a good success rate. Fig. 5 can be seen as different success rates of Zigbee STAs joining a communication transmission operation (Server) when WiFi has different traffic in TX/RX directions, where the Y-axis can be defined as the success rate of Zigbee STAs joining a Zigbee Server, and the X-axis can be defined as the success rate of WiFi transmitting 20/25/30/35/40/45/50Mbps traffic in TX/RX directions, respectively. Wherein, the direction of WiFi CoEx- > WlFi Remote is defined as TX, and the direction of WlFi Remote- > WlFi CoEx is defined as RX.
The above-described embodiments are merely exemplary for convenience in explanation, and the scope of the claims of the present invention should be determined by the claims rather than by the limitations of the above-described embodiments.
