The wireless module 110 may be coupled to one or more antennas (not shown) and may allow a wireless network to be used to communicate with one or more additional devices, computers, and/or servers.

Specifically, the first network element 112 uses the same communication protocol as the first network 310 and the second network element 114 uses the same communication protocol as the second network 320. For example, when the first network 310 is a bluetooth network using bluetooth technology and the second network 320 is a WiFi wireless network, the first network element 112 is a bluetooth element compatible with the bluetooth technology used, the second network element 114 is a wireless network element compatible with Wi-Fi technology used, and so on.

Similarly, the target device 200 may comprise at least a communication module (not shown), a processor (not shown), and a storage device (not shown). The communication module can receive signals from the current connection network and transmit the signals to the current connection network.

In this embodiment, the communication module of the target device 200 at least includes network elements corresponding to the first network element 112 and the second network element 114, which are respectively used to connect to the first network 310 and the second network 320, so that the target device 200 can perform signal transmission and reception with the mobile device 100 through the first network 310 and can also perform signal transmission and reception with the mobile device 100 through the second network 320.

In other words, the target device 200 can be regarded as a small computing device with independent operation capability, and can independently operate a specific operating system.
In some embodiments, the target device 200 may include various sensors or detectors (e.g., temperature sensors, light sensors, humidity sensors, etc.) that may be used to collect or measure various sensor data, such as various sensed data relating to the environment, e.g., temperature, humidity, etc. The target device 200 may transmit the collected or measured sensor data to the mobile device 100 after connecting to a corresponding mobile device 100 through a connection network (e.g., the second network 320).
Fig. 3 is a flowchart illustrating a method for determining a data transmission rate of a network according to an embodiment of the invention. The method for determining the data transmission rate of the network according to the embodiment of the present invention can be applied to the mobile device 100 shown in fig. 2. For example, the method may be performed by the processor 120 of the mobile device 100 shown in fig. 2.
First, in step S302, the processor 120 detects a broadcast signal from one or more target devices 200 of a first network via the first network element 112 of the wireless module 110. Specifically, in the present disclosure, each of the active target devices 200 continuously transmits a broadcast signal to the first network 310. Wherein, each device continuously sends out broadcast signals by means of beacons (beacons). Any micropositioning signal transmitter that employs bluetooth low energy (BLE or bluetooth 4.0) can be referred to as Beacon. In short, Beacon is like a Beacon continuously broadcasting signals, when the mobile device 100 enters the range of the Beacon, Beacon will send the broadcast signals to the mobile device 100, and the mobile device 100 will trigger a series of actions after detecting the broadcast signals. The broadcast signal sent by each target device 200 may include its corresponding identification information, such as mac address and code of each target device 200. The mobile device 100 may detect all broadcast signals via the first network element 112.
Next, in step S304, the processor 120 determines the number of the target devices 200 according to the received broadcast signal. Since the broadcast signal of each target device 200 includes its corresponding identification information, the processor 120 may determine the number of target devices 200 in the environment according to the number of received broadcast signals. For example, when the processor 120 receives 10 broadcast signals from the first network 310 in total, the processor 120 may determine that the number of target devices 200 is 10. In some embodiments, the mobile device 100 may have a list including identification information of all valid target devices, and the processor 120 may filter out invalid other devices with reference to the list to avoid false determination. For example, the processor 120 may receive 10 broadcast signals in total from the first network 310, but the identification information of 2 broadcast signals is not in the list, so the processor 120 may determine that the number of target devices 200 is 8.
After determining the number of the target devices 200, in step S306, the processor 120 determines the data transmission rate corresponding to the second network 320 as a first data transmission rate or an adjusted second data transmission rate according to whether the determined number of the target devices 200 meets a predetermined condition, and performs data transmission on the second network 320 through the second network element 114 at the determined data transmission rate. For example, when the processor 120 determines that the data transmission rate corresponding to the second network 320 is the second data transmission rate, the processor 120 may perform data transmission with a corresponding target device of the target devices 200 in the second network 320 at the second data transmission rate, for example, may transmit a control command to the corresponding target device 200 through the second network 320 or receive data such as sensor data from the corresponding target device 200.
Specifically, the predetermined condition is used to determine whether the current network is congested (i.e., whether the network bandwidth is sufficient), which can be generated according to an empirical rule or defined by the user according to the conditions of the usage environment (e.g., the available bandwidth of the environment or the performance and bandwidth capacity of the gateway device controlling all devices in use).
In an embodiment, the determining of the data transmission rate corresponding to the second network as the first data transmission rate or the second data transmission rate by the processor 120 according to whether the number of the target devices is greater than an upper limit value includes: when the number of the target devices 200 is not higher than the upper limit, determining the data transmission rate corresponding to the second network to be the first data transmission rate (for example, the first data transmission rate is a preset 1 kbps); and when the number of the target devices 200 is higher than the upper limit value, turning down the first data transmission rate to generate a second data transmission rate (for example, the second data transmission rate is 0.5kbps), and determining the data transmission rate corresponding to the second network as the second data transmission rate. The upper limit value can be generated according to an empirical rule or can be defined by a user according to the conditions of the usage environment (e.g., the available bandwidth of the environment or the performance and bandwidth capacity of the gateway device controlling all devices in use). When the number of target devices is higher than the upper limit, it indicates that the network bandwidth is insufficient, and the data transmission rate must be reduced.
In another embodiment, the predetermined condition may be whether the number of target devices is lower than a lower limit, and the step of determining, by the processor 120, the data transmission rate corresponding to the second network to be the first data transmission rate or the second data transmission rate according to whether the number of target devices meets the predetermined condition further includes: when the number of the target devices is not lower than the lower limit, the processor 120 determines that the data transmission rate corresponding to the second network 320 is a first data transmission rate (for example, the first data transmission rate is a preset 1 kbps); and when the number of the target devices is lower than the lower limit, the processor 120 increases the first data transmission rate to generate a second data transmission rate (for example, the second data transmission rate is 1.5kbps), and determines the data transmission rate corresponding to the second network 320 as the second data transmission rate. The lower limit value can be generated according to an empirical rule or can be defined by a user according to the conditions of the usage environment (e.g., the available bandwidth of the environment or the performance and bandwidth capacity of the gateway device controlling all devices in use). When the number of the target devices is lower than the lower limit value, it indicates that the current network bandwidth is sufficient, and the data transmission rate can be increased.
Fig. 4 is a flowchart illustrating a method for determining a data transmission rate of a network according to another embodiment of the present invention, for dynamically adjusting the data transmission rate of the network according to the number of target devices 200. The method for determining the data transmission rate of the network according to the embodiment of the present invention can be applied to the mobile device 100 shown in fig. 2. For example, the method may be performed by the processor 120 of the mobile device 100 shown in fig. 2.
When the mobile device 100 intends to perform data transmission with the corresponding target device 200 through the second network 320, in step S402, the mobile device 100 first performs data transmission on the second network 320 at a predetermined first data transmission rate (e.g., the first data transmission rate is a predetermined 1 kbps).
During the data transmission process, in step S404, the processor 120 continuously determines whether the number of the target devices 200 is higher than the set upper limit. If the number of the target devices 200 is higher than the upper limit (yes in step S404), it indicates that the current network bandwidth is insufficient and the speed reduction is required, so the processor 120 reduces the data transmission rate from the first data transmission rate to the second data transmission rate and performs data transmission on the second network 320 at the second data transmission rate (e.g., the second data transmission rate is 0.5kbps), in step S406. On the contrary, if the number of the target devices 200 is not higher than the upper limit (no in step S404), then, in step S408, the processor 120 determines whether the number of the target devices 200 is lower than a lower limit. If the number of the target devices 200 is lower than the lower limit (yes in step S408), it indicates that the current network bandwidth is sufficient to increase the data transmission rate, and then, in step S410, the processor 120 increases the data transmission rate from the first data transmission rate to a third data transmission rate (e.g., from a predetermined 1kbps to 1.5kbps), and performs data transmission on the second network 320 at the third data transmission rate. If the number of the target devices 200 is not higher than the upper limit or lower than the lower limit (no in step S408), it indicates that the current data transmission rate does not need to be adjusted, and therefore, in step S412, the processor 120 maintains the data transmission rate of the second network 320 unchanged. It is understood that the processor 120 may adjust the data transmission rate up or down in various adjustment manners, such as in a fixed ratio (e.g., half or a certain ratio of the preset transmission rate up) or in an increasing or decreasing manner (e.g., ten percent of each up or down).
Therefore, each mobile device in the environment can utilize the mechanism to dynamically adjust its own data transmission rate for the network at a proper time, thereby dynamically adjusting the speed of the command transmitted to the target device, effectively increasing the number of available devices under limited bandwidth and making data transmission smooth, and avoiding various problems caused by network congestion.
In some embodiments, after the mobile device 100 throttles down the data transmission for the downspeed data transmission, the mobile device 100 may continue to receive the bluetooth identification signal in the environment through the first network component 112 (e.g., a bluetooth component), determine a change in the number of target devices in use, and determine whether to throttle up the data transmission rate of the first network 310 (e.g., a WiFi wireless network) according to the number of target devices in use. Specifically, a lower limit value may be preset, and when the determined number of target devices in use is lower than the lower limit value, it indicates that the current network bandwidth is sufficient, and the accelerated data transmission may be performed. The lower limit value can be generated empirically or defined by the user based on the conditions of the environment (e.g., the available bandwidth of the environment or the performance and bandwidth capacity of the gateway device controlling all devices in use).
In some embodiments, after the mobile device 100 adjusts the data transmission rate up for the reduced speed data transmission, the mobile device 100 may continuously receive the bluetooth identification signal in the environment through the bluetooth element, determine the change of the number of the target devices 200 in use, and determine whether to adjust the data transmission rate of the WiFi wireless network down for the reduced speed data transmission according to the number of the target devices 200 in use.
The following embodiments are provided to assist in describing the method for determining the data transmission rate of the network and the practical application details according to the present invention, but the present invention is not limited thereto.
Fig. 5 is a flowchart illustrating a method for determining a data transmission rate of a network according to another embodiment of the invention, for dynamically adjusting the data transmission rate of the network. The method according to the embodiment of the present invention may be applied to the mobile device 100 shown in fig. 2. Please refer to fig. 1, fig. 2 and fig. 5. In the present embodiment, it is assumed that the first network 310 is a bluetooth network, the second network 320 is a WiFi wireless network, the first network element 112 is a bluetooth element, and the second network element 114 is a WiFi wireless network element. In the environment 10, there are a plurality of target devices 200 and the same number of mobile devices 100, and each target device 200 and a corresponding mobile device 100 perform data transmission through the WiFi wireless network and continuously send out a broadcast signal containing identification information thereof to the bluetooth network in a beacon manner.
First, the mobile device 100 performs data transmission on the WiFi wireless network at a predetermined data transmission rate via the WiFi wireless network element (step S502) and receives a plurality of broadcast signals from the bluetooth network via the bluetooth element to determine the congestion level of the current network (step S504).
In the present embodiment, it is assumed that the upper limit is 10 and the mobile device 100 receives the broadcast signal sent by 11 target devices 200 from the bluetooth network, so that the mobile device 100 determines that the number of target devices 200 in the environment is higher than the upper limit according to the received broadcast signal (step S506), and therefore determines that the number of target devices 200 meets the predetermined condition, and then the mobile device 100 reduces the data transmission rate of the WiFi wireless network and performs speed reduction data transmission on the WiFi wireless network at the reduced data transmission rate (step S508).
After the reduced data transmission rate is performed on the WiFi wireless network, the mobile device 100 continuously detects the number of the target devices 200 in the environment. After a period of time, when the mobile device 100 detects that the number of the target devices 200 in the environment is continuously lower than the upper limit (step S510), which indicates that the situation of insufficient network bandwidth has improved, the mobile device 100 determines that the number of the target devices 200 meets the predetermined condition, increases the data transmission rate of the WiFi wireless network, and performs accelerated data transmission on the WiFi wireless network at the increased data transmission rate (step S512).
In some embodiments, a method for determining a data transmission rate of a wireless network according to the determined target device is also provided.
Fig. 6 is a flowchart illustrating a method for determining a data transmission rate of a network according to an embodiment of the invention. The method for determining the data transmission rate of the network according to the embodiment of the present invention can be applied to the mobile device 100 shown in fig. 2. For example, the method may be performed by the processor 120 of the mobile device 100 shown in fig. 2.
First, in step S602, the processor 120 detects a broadcast signal from one or more target devices 200 of the first network 310 via the first network element 112 of the wireless module 110. Specifically, in the present disclosure, each of the target devices 200 in use continuously transmits a broadcast signal to the first network 310, wherein the broadcast signal sent by each of the target devices 200 may include its corresponding identification information, such as the mac address of each of the target devices 200. The mobile device 100 may detect all broadcast signals via the first network element 112.
Next, in step S604, the processor 120 determines the number of the target devices 200 according to the received broadcast signal. Since the broadcast signal of each target device 200 includes its corresponding identification information, the processor 120 may determine the number of target devices 200 in the environment according to the number of received broadcast signals.
After determining the number of the target devices 200, in step S606, the processor 120 determines the data transmission rate corresponding to the first network 310 as a first data transmission rate or an adjusted second data transmission rate according to whether the determined number of the target devices 200 meets a predetermined condition, and performs data transmission on the first network 310 through the first network element 112 at the determined data transmission rate.
In an embodiment, the determining whether the number of the target devices is higher than an upper limit value and the determining, by the processor 120, the data transmission rate corresponding to the first network to be the first data transmission rate or the second data transmission rate according to whether the number of the target devices meets the predetermined condition includes: when the number of the target devices 200 is not higher than the upper limit, determining the data transmission rate corresponding to the first network to be a first data transmission rate (for example, the first data transmission rate is a preset 1 kbps); and when the number of the target devices 200 is higher than the upper limit, turning down the first data transmission rate to generate a second data transmission rate (e.g., the second data transmission rate is 0.5kbps), and determining the data transmission rate corresponding to the first network 310 as the second data transmission rate.
In another embodiment, the predetermined condition may be whether the number of target devices is lower than a lower limit, and the step of determining, by the processor 120, the data transmission rate corresponding to the second network to be the first data transmission rate or the second data transmission rate according to whether the number of target devices meets the predetermined condition further includes: when the number of the target devices is not lower than the lower limit, the processor 120 determines that the data transmission rate corresponding to the first network 310 is a first data transmission rate (for example, the first data transmission rate is a preset 1 kbps); and when the number of the target devices is lower than the lower limit, the processor 120 increases the first data transmission rate to generate a second data transmission rate (for example, the second data transmission rate is 1.5kbps), and determines the data transmission rate corresponding to the first network 310 to be the second data transmission rate.
Therefore, according to the mobile device supporting multiple networks and the method for determining the data transmission rate of the network of the present invention, the data transmission rate of another network can be dynamically adjusted by detecting the congestion degree of one network, so as to adjust the transmission speed of the data signal, so that the data transmission is smooth under the limited network bandwidth and the network bandwidth is not blocked.
The method of the present invention, or a specific form or part thereof, may be in the form of program code. The program code may be embodied in tangible media, such as floppy diskettes, cd-roms, hard drives, or any other machine-readable (e.g., computer-readable) storage medium, wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the invention.
