Referring to fig. 2, fig. 2 is a schematic flow chart of a communication control method provided in an embodiment of the present application, where the method may include, but is not limited to, the following steps:
201. receiving a plurality of resource query response messages sent by a plurality of relay devices, wherein each resource query response message comprises a resource use state and a device state of a channel allocated by the corresponding relay device;
specifically, it can be understood that, when a communication link switching instruction is detected, the electronic device determines whether to perform Wi-Fi access point switching. If yes, broadcasting resource query request messages on the plurality of channels allocated by the plurality of relay devices, and after the plurality of relay devices receive the resource query request messages broadcast by the first electronic device, sending resource query response messages to the first electronic device, wherein each resource query response message comprises a resource use state and a device state of the channel allocated by the corresponding relay device.
202. Detecting signal strengths of the plurality of relay devices;
specifically, it may be understood that, after receiving a plurality of resource query response messages, the first electronic device obtains signal strengths of the plurality of relay devices; or the signal strengths of the plurality of relay devices may be obtained after the resource query request message broadcast by the first electronic device.
203. Determining access quality of each relay device in the plurality of relay devices according to the signal strength, the resource usage status and the device status;
specifically, it may be understood that, after acquiring the signal strengths of the plurality of relay devices, and the resource usage state and the device state of the channel allocated by the corresponding relay device, the first electronic device may perform calculation and evaluation on the access quality of each relay device in the plurality of relay devices.
204. Determining a second relay device of the plurality of relay devices according to the access quality;
specifically, it may be understood that, after the first electronic device determines the access quality of each of the plurality of relay devices, one relay device meeting the access standard is selected as a relay device for the next Wi-Fi access, that is, a second relay device.
205. And accessing a Wi-Fi access point of the second relay device.
Specifically, it can be understood that after determining the next relay device that is accessed by Wi-Fi, that is, the second relay device, the first electronic device may automatically connect to the second relay device, so as to ensure the continuity of the communication process.
It can be seen that, in the embodiment of the application, the first electronic device is connected with a relay device (which may be a CPE) having a wireless high-fidelity Wi-Fi access point, when the Wi-Fi access point is to be switched, access quality of a plurality of wireless relay devices is determined through a plurality of acquired resource query response messages, and a relay device capable of meeting own communication requirements is selected according to an access policy to serve as a next Wi-Fi access point. Through the mode of evaluating first and then accessing, the continuity of the communication process is guaranteed, and the communication quality is effectively improved.
In one possible example, the multiple relay devices are relay devices that only support wireless access to a frequency band of a fourth generation mobile communication technology 4G network, or relay devices that support a sub-6GHz frequency band of a fifth generation mobile communication technology 5G new air interface NR network, where the device states include device temperature and processor occupancy;
the determining the access quality of each of the plurality of relay devices according to the signal strength, the resource usage status, and the device status includes: and determining the access quality of each relay device according to the signal strength, the resource use state, the device temperature, the processor occupancy rate and a preset formula.
Specifically, when the plurality of relay devices are relay devices supporting a Frequency band of a 4G network, or relay devices supporting a Sub-6GHz Frequency band of a 5G new air interface NR network in a wireless access fifth-generation mobile communication technology, a Frequency Range (FR) 1 of the 4G new air interface NR network in a 2.6GHz Frequency band used by the 4G network is 450MHz to 6GHz, which is also called Sub6G (lower than 6 GHz). FR1 has the advantages of low frequency, strong diffraction capability and good coverage effect, and is the current 5G main frequency spectrum. FR1 is mainly used as a basic coverage frequency band, and supports a bandwidth of 100Mbps at most. The part below 3GHz comprises the frequency spectrums of 2G, 3G and 4G which are used at present, and the quick deployment of the 5G network can be realized by utilizing part of resources of old station sites in the initial stage of network construction. In the relay equipment supported by the two frequency bands, due to the diffraction capability of the wireless network, the signal strength and the stability of the relay equipment are less influenced by the outside, but are greatly influenced by the self factors of the equipment, namely the self state of the equipment, including the temperature of the equipment, and the occupancy rate of a processor of the equipment. Therefore, when determining the access quality of each relay device in the plurality of relay devices, the signal strength of the relay device, the resource use state and the device temperature, the processor occupancy rate are fully considered, and the access quality of each relay device is calculated according to a preset formula.
Therefore, considering that the relay equipment can more easily acquire the influence factors of the signal quality of the relay equipment according to the frequency band characteristics, the access quality of each relay equipment is determined to be more accurate.
In one possible example, the preset formula is:
wherein Q isiFor the access quality of the ith relay device, XiFor the signal strength of the ith relay device,
is the weight of the signal strength of the i-th relay device, SinIs the nth idle channel bandwidth, W, of the ith relay deviceiThe bandwidth of the ith relay device,
is the resource usage status of the ith relay device, beta is the weight of the resource usage status of the ith relay device, FiIs the temperature of the i-th relay device, YiProcessor occupancy of the i-th relay device, Fi*YiIs the device status value of the ith relay device, θ is the weight of the device status value of the ith relay device, and e is the error.
Specifically, when i is 1, that is, when the access quality of the first relay device is calculated, the signal strength X of the first relay device is acquired1，
For a predetermined weight of the signal strength of the first relay device, e.g.
Equal to 50%, when said first relay device comprises a first idle channel and a second idle channel, S11Is a first free channel bandwidth, S, of the first relay device12Is a second free channel bandwidth, W, of the first relay device1A bandwidth of the first relay device is greater than a bandwidth of the second relay device,
a resource usage status of the first relay device; of course, the first relay device may further include a third idle channel and a fourth idle channel. β is a weight of the resource usage state of the first relay device, and may be equal to 50%, 20%, 80%, or the like, for example; f1For the temperature of said first relay device, e.g. when the temperature of the relay device is between certain values, F1At the highest value, the temperature of the first relay device is higher than or equal to this intermediate value, F, every time higher or lower than 1 or 2 degrees1And sequentially decreasing according to preset values. Y1 is the same asThe processor occupancy of a relay device may be the same as F1The determination principle is the same, and the detailed description is omitted here. F1 × Y1 is the device status value of the first relay device, θ is the weight of the device status value of the first relay device, for example, θ is 20%, and may also be equal to 40%, 30%, 70%, etc.; e is an error, which may have an effect on the access quality of the first relay device, but is not included in the signal strength, the resource usage status and the device status. When i is 2, the formula calculates the access quality of the second relay device, and similarly, i may also be equal to 3, 4 … … n.
Therefore, the access quality of each relay device in the plurality of relay devices is calculated through the formula, and each influence factor is quantized, so that the evaluation result is more accurate.
In one possible example, the multiple relay devices are relay devices supporting wireless access to a millimeter wave frequency band of a 5G new air interface NR network of a fifth generation mobile communication technology, the device state includes a location scenario where the device is located,
the determining the access quality of each of the plurality of relay devices according to the signal strength, the resource usage status, and the device status includes: determining the reference access quality of each relay device in the plurality of relay devices according to the signal strength and the resource use state; determining an access quality correction coefficient of each relay device according to the position scene, wherein the access quality correction coefficient is used for representing the network access stability of the relay device in the corresponding position scene; and determining the access quality of each relay device according to the reference access quality and the access quality correction coefficient.
Specifically, when the plurality of relay devices are relay devices supporting wireless access to a millimeter Wave Frequency band of a 5G new air interface NR network in the fifth generation mobile communication technology, the Frequency Range (FR) 2 of the 5G new air interface NR network is millimeter Wave (mm Wave). FR2 is mainly used as a capacity supplementary frequency band, the maximum bandwidth of 400Mbps is supported, many high-speed applications can be realized based on the frequency spectrum in the future, and the peak rate of 5G up to 20Gbps is also based on the ultra-large bandwidth of FR 2. The frequency range of FR2 is 24GHz to 52GHz, and the electromagnetic wave wavelengths of this spectrum are mostly in the millimeter level. Its advantages are very large bandwidth, clean spectrum, less interference, and low diffraction power as the subsequent 5G expanding frequency. Therefore, the relay device supported by the frequency band is greatly interfered by the outside world, and the stability of the signal is affected by the position scene of the device. Therefore, when the access quality of the relay device is determined, the signal strength of the device and the resource usage status are obtained, and the reference access quality of each relay device in the plurality of relay devices is determined, which may be specifically determined as described in the foregoing embodiment. And in addition, determining an access quality correction coefficient of each relay device according to the location scene, wherein the access quality correction coefficient is used for representing the network access stability of the relay device in the corresponding location scene. For example, the relay devices located in the living room or the bedroom are different in the positions, the interference factors and the time periods of the interference factors, so that the correction coefficients are different. And finally, determining the access quality of each relay device according to the reference access quality and the access quality correction coefficient.
Therefore, considering the relay device supporting the millimeter wave frequency band of the wireless access fifth generation mobile communication technology 5G new air interface NR network, due to the characteristics of short wavelength and poor diffraction capability, the network access stability of the relay device is affected by different position scenes, and the determined access quality of the relay device is more accurate.
In one possible example, the determining the access quality correction factor of each relay device according to the location scenario includes: acquiring a plurality of network access records of each relay device in the corresponding scene position; the network access records are statistically analyzed to obtain the network disconnection probability of each relay device; and determining the access quality correction coefficient according to the network outage probability, wherein the network outage probability and the access quality correction coefficient are in an inverse proportional relation.
Specifically, as shown in table 1, in the detection time period of 8:00-24:00, the number of the first relay devices and the second relay devices located in the bedroom are 8, 9, each device is actively connected to the relay device once, for example, when the first electronic device is connected to the first relay device all the time during the period of 18:00-20:00, if one electronic device is connected to the first relay device, the first electronic device is connected to the first relay device again during the period of 21:00-22:00, the electronic device connected to the first relay device is added, and similarly, the same can be said. The network disconnection coefficient is the disconnection of the connected electronic device due to the signal strength of the relay device and the device state, and is recorded as a network disconnection. Therefore, from table 1, it is easy to find that the correction factor of the first relay device is 8/9, and the correction factor of the second relay device is 9/6, which also reflects that the first relay device has a higher network outage probability than the second relay device.
Therefore, the network disconnection probability of each relay device is obtained by obtaining a plurality of network access records of each relay device in the corresponding scene position and carrying out statistical analysis on the network access records, the access quality correction coefficient is determined according to the network disconnection probability to weight the reference access quality of the corresponding relay device, and the temperature degree of the signal of the relay device in a certain time period and the equilibrium state of the network can be accurately obtained.
TABLE 1
In one possible example, the determining a second relay device of the plurality of relay devices according to the access quality comprises: determining any one relay device with access quality greater than preset access quality in the plurality of relay devices as a second relay device; or, determining the relay device with the highest access quality in the plurality of relay devices as the second relay device.
Specifically, after the access quality of each of the plurality of relay devices is determined, any one of the relay devices having an access quality greater than a preset access quality may be selected as the second relay device, and the relay device having the highest access quality may also be selected as the second relay device. However, in any selection manner, the communication requirement of the first electronic device is satisfied.
Therefore, on the premise of meeting the communication requirement of the first electronic device, a diversified selection mode is adopted instead of only selecting the relay device with the highest access quality as the second access device, so that network resources in the whole regional environment can be configured more reasonably.
In one possible example, the Wi-Fi access point accessing the second relay device includes: the method comprises the steps of carrying out transmission priority sequencing on application data of local terminal equipment to obtain the transmission priority of the data of each application; and carrying out data transmission through the communication link with the second relay equipment according to the sequence from high transmission priority to low transmission priority.
Specifically, before or after determining that the second relay device is used as the next Wi-Fi access point, the transmission priority of data of each application of the local device may be determined, and channels may be allocated according to the priority order to perform data transmission. For example, if the second relay device includes a first channel, the first channel is allocated to the application with the optimal priority in the first electronic device; if the second relay device comprises a first channel and a second channel, and the information transmission capability of the first channel is better than that of the second channel, the first channel is allocated to the application with the optimal priority in the first electronic device, and the second channel is allocated to the application with the suboptimal priority in the first electronic device; wherein the information transmission capability of the first channel is better than that of the second channel, including: the transmission rate of the first channel is higher than the transmission rate of the second channel; or the load of the sub-carrier of the first channel is higher than that of the sub-carrier of the second channel; or the average signal power of the first channel is higher than that of the second channel; or the noise average power of the first channel is lower than the signal average power of the second channel.
If each of the plurality of relay devices cannot meet the transmission requirements of the plurality of application data of the first electronic device, the first electronic device may simultaneously connect two relay devices with higher access quality to transmit the application data.
And according to the number of idle channels of the second relay equipment and the difference of the quality, distributing the application data with different priorities in the local terminal equipment to transmit, and optimizing the data transmission rate of the local terminal equipment.
Referring to fig. 3, in accordance with the embodiment shown in fig. 2, fig. 3 is a schematic flowchart of another communication control method provided in the embodiment of the present application, and as shown in the drawing, the method includes the following steps:
301. receiving a plurality of resource query response messages sent by a plurality of relay devices, wherein each resource query response message comprises a resource use state and a device state of a channel allocated by the corresponding relay device;
302. detecting signal strengths of the plurality of relay devices;
303. determining access quality of each relay device in the plurality of relay devices according to the signal strength, the resource usage status and the device status;
304. determining a second relay device of the plurality of relay devices according to the access quality;
305. the method comprises the steps of carrying out transmission priority sequencing on application data of local terminal equipment to obtain the transmission priority of the data of each application;
specifically, the transmission priority ordering of the application data of the local device may be performed according to any one of the following orders:
using the frequency of the application, and the preset priority order of the application;
applying the channel bandwidth requirement of the transmission data; for example, the higher the requirement on the channel bandwidth, the higher the corresponding priority;
applying the fault tolerance rate of the transmission data, wherein the lower the fault tolerance rate, the higher the corresponding priority;
the requirement of the time-ductility is applied, and the shorter the requirement of the time-ductility is, the higher the corresponding priority is.
306. And carrying out data transmission through the communication link with the second relay equipment according to the sequence from high transmission priority to low transmission priority.
Specifically, before or after determining that the second relay device is used as the next Wi-Fi access point, the transmission priority of data of each application of the local device may be determined, and channels may be allocated according to the priority order to perform data transmission. For example, if the second relay device includes a first channel, the first channel is allocated to the application with the optimal priority in the first electronic device; if the second relay device comprises a first channel and a second channel, and the information transmission capability of the first channel is better than that of the second channel, the first channel is allocated to the application with the optimal priority in the first electronic device, and the second channel is allocated to the application with the suboptimal priority in the first electronic device; wherein the information transmission capability of the first channel is better than that of the second channel, including: the transmission rate of the first channel is higher than the transmission rate of the second channel; or the load of the sub-carrier of the first channel is higher than that of the sub-carrier of the second channel; or the average signal power of the first channel is higher than that of the second channel; or the noise average power of the first channel is lower than the signal average power of the second channel.
If each of the plurality of relay devices cannot meet the transmission requirements of the plurality of application data of the first electronic device, the first electronic device may simultaneously connect two relay devices with higher access quality to transmit the application data.
Therefore, when a new relay device is selected for connection, the communication quality can be better guaranteed only by considering the access quality of the relay device and the priority sequence of the application transmission data of the local terminal and combining the internal and external influence factors of the local terminal.
Referring to fig. 4, fig. 4 is a schematic structural diagram of functional units of a communication control apparatus 400 according to an embodiment of the present application, which is applied to a first electronic device of a communication control system, and includes a communication unit, a detection unit and a processing unit, where,
as shown, the communication control apparatus 400 includes: a communication unit 410, a detection unit 420 and a processing unit 430, wherein:

the processing unit 430 is further configured to perform Wi-Fi access point switching according to the Wi-Fi access point switching policy.
It can be seen that, in the embodiment of the present application, the plurality of functional units of the communication control apparatus 400 enable the first electronic device to connect and communicate with the relay device having the wireless high-fidelity Wi-Fi access point. When the Wi-Fi access point is to be switched, the access quality of a plurality of wireless relay devices is determined through a plurality of acquired resource query response messages, and the relay device which can meet the communication requirement of the relay device is selected as the next Wi-Fi access point according to an access strategy. Through the mode of evaluating first and then accessing, the continuity of the communication process is guaranteed, and the communication quality is effectively improved.
In one possible example, the multiple relay devices are relay devices that only support wireless access to a frequency band of a fourth generation mobile communication technology 4G network, or relay devices that support a sub-6GHz frequency band of a fifth generation mobile communication technology 5G new air interface NR network, where the device states include device temperature and processor occupancy;
in the aspect of determining the access quality of each relay device in the plurality of relay devices according to the signal strength, the resource usage status, and the device status, the processing unit 430 is specifically configured to determine the access quality of each relay device according to the signal strength, the resource usage status, and the device temperature, the processor occupancy, and a preset formula.
In one possible example, the preset formula is:
wherein Q isiFor the access quality of the ith relay device, XiFor the signal strength of the ith relay device,
is the weight of the signal strength of the i-th relay device, SinIs the nth idle channel bandwidth, W, of the ith relay deviceiThe bandwidth of the ith relay device,
