technical field

The present application relates to the field of electronic technologies, and in particular, to a communication resource cooperation method and an electronic device.

Background technique

With the development of communication technology and the popularization of smart devices, the era of artificial intelligence & internet of things (AIoT) is coming. Benefiting from the improvement of the distributed interconnection capability of the operating system, devices such as smart wearable devices, smart home devices, and mobile terminals can interact with data through the network, and cooperate to achieve specific functions based on the data interaction.

Electronic devices such as smart wearable devices, smart home devices, and mobile terminals can already realize data interaction through wireless networks. However, compared to the communication resource requirements of multiple electronic devices, the communication resources that can be used in the space are limited. For example, when multiple devices access the wireless network provided by the same access device, the multiple devices need to compete for limited wireless air interface resources for data interaction. After the electronic device fails to compete for wireless air interface resources, the electronic device temporarily stores the data to be sent locally, and waits for the next competition to succeed.

Since devices must compete to obtain limited communication resources, the competition process will inevitably increase the delay of the device interaction process, and lead to the instability of the device interaction process delay. When there are low-latency services running on the device, the increase in the delay of the interaction process and the instability of the delay will greatly deteriorate the user experience. However, when the service running on the device is a non-low-latency service, the increase of the delay in the interaction process and the instability of the delay will make the user's perception weaker, so the impact on the user experience is small.

For example, device 1 and device 2 perform data exchange on channel 1 respectively, and the delay of wireless channel 1 in a certain period of time is about 500ms. Device 1 runs a screen casting service (low-latency service), and device 2 runs a download service (non-low-latency service). The delay of channel 1 cannot meet the requirements of the screen projection service, and the delay of channel 1 can meet the requirements of the download service. Users can clearly perceive the freeze of the screen projection service, but it is difficult to perceive the freeze of the download service.

After the device is connected to the wireless network, when the service experience on the device does not meet the requirements, it can actively switch channels. For the device, the communication quality of the channel after the handover may be worse than the quality of the channel before the handover, and performing data exchange on the channel after the handover will lead to increased interaction delay and instability. For electronic devices running low-latency services, choosing to actively switch channels may deteriorate the user experience.

For ease of understanding, related terms and related concepts involved in the embodiments of the present application are first introduced below. The terms used in the embodiments of the present invention are only used to explain specific embodiments of the present invention, and are not intended to limit the present invention.

(1) Low-latency services, other services

Applications/service sessions can be divided into low-latency services and other services according to their own requirements for the latency of data interaction. When an application or a service session initiated by an application on the device is sensitive to the delay of data interaction, the application/service session is considered to be a low-latency service; When the delay is not sensitive, the application/service session is considered to be other services. Among them, in an end-to-end (peertopeer, P2P) scenario, the delay of data interaction can be referred to as the interaction delay, which means that one end of the network is ready to start sending data, and the other end of the network finishes receiving and processing the data. required time.

Low-latency services can take many forms, mainly including two forms. First, low-latency services can include applications/service sessions that enable streaming data from one device to another. For example, streaming media data such as PPT and online video on the mobile phone can be projected onto the TV, VR/AR and other devices. The application/service session is a low-latency service. Second, low-latency services may include application/service sessions that transmit control commands. For example, the game needs to send the user's game instructions to the server in time, and the game is a low-latency service; or, the application/service session responsible for the interaction between the manufacturing equipment in the factory and the industrial control instructions of the central equipment is a low-latency service.

Optionally, in some embodiments of the present application, other services may be further classified into general services and high-throughput services. When a service session initiated by an application on a device transmits a large amount of data per unit of time, the application/service session is considered to be a high-throughput service.

In this embodiment of the present application, when the application/service session is both a low-latency service and a high-throughput service, the service is considered to be a low-latency service.

In this embodiment of the present application, the application/service session on the device may be configured with its own service type statically or dynamically. The static configuration may include: an application/service session on the device can preconfigure itself as a low-latency service/other service, and can declare itself as a low-latency service or other service to other electronic devices. The dynamic configuration may include: preconfiguring a parameter threshold for the application/service session on the device, and the device may determine the service type of the application/service session by evaluating the communication quality or experience quality of the current application/service session.

Optionally, in some embodiments of the present application, the application/service session on the device may be preconfigured as a low-latency service/other service.

Optionally, in some embodiments of the present application, the device/operating system may designate any application/service session as a low-latency service/other service.

Optionally, in some embodiments of the present application, an application/service session on the device may be preconfigured with a delay threshold, and when the channel delay/interaction delay is greater than or equal to the delay threshold, the application/service session It is a low-latency service; correspondingly, when the channel delay is less than the delay threshold, the application/service session is other services.

Optionally, in some embodiments of the present application, the application/service session on the device may evaluate its own quality of experience (quality of experience, QoE) parameter, and a QoE threshold may be preconfigured. When the QoE is less than or equal to the QoE threshold, the application/service session is a low-latency service; correspondingly, when the QoE is greater than the QoE threshold, the application/service session is other services. Among them, QoE is a comprehensive evaluation parameter of the user's subjective feeling of the service during the user's interaction with the service. QoE can have different calculation methods and expressions according to different applications/service sessions. For example, QoE may be the comprehensive evaluation result of part or all of parameters such as uplink and downlink air interface channel delay, bandwidth, and network jitter in the data exchange of the application/service session, which is not limited here.

For the concepts of terms such as interaction delay and channel delay, reference may be made to the text description in (3) Wireless Channel in Terminology Interpretation, which will not be repeated here.

The following takes the content shown in FIG. 1 as an example to exemplarily introduce low-latency services and non-low-latency services.

Figure 1 (A) shows a low-latency service scenario. As shown in Figure 1 (A), the mobile phone establishes a WIFI connection with the projector, and transmits the PPT displayed on the screen of the mobile phone to the projector through the WIFI connection on display. Among them, the projection service is a low-latency service. When the air interface resources are limited or the channel signal-to-noise ratio is low, the interaction delay is relatively large and/or the interaction delay is unstable. As shown in Figure 1 (A), at the 0th second, the user starts to display the first page of PPT on the mobile phone, and waits for 0.5 seconds before viewing the content of the first page of PPT on the projector; at the 0.7th second , the user switches to the second page of PPT on the mobile phone, and waits for 0.4 seconds before viewing the content of the second page of PPT on the projector.

In contrast, (B) in FIG. 1 shows a high-throughput service scenario. As shown in (B) of FIG. 1 , the mobile phone 1 and the mobile phone 2 establish a WIFI connection, and the video files are transmitted from the mobile phone 1 to the mobile phone 2 through the WIFI connection. Among them, the video transmission service is a high-throughput service. Similarly, when the interaction delay is large and/or the interaction delay is unstable, at the 0th second, the mobile phone 1 starts to transmit the video file to the mobile phone 2; at the 0.5th second, the mobile phone 2 starts to receive the mobile phone 1. The data sent; at the 35th second, the mobile phone 1 sends all the data of the video file; at the 35.3th second, the mobile phone 2 receives all the data of the video file.

As shown in (A) in Figure 1, every time the user switches the PPT on the mobile phone, he can obviously feel the increase of the interaction delay and the feeling of stuttering caused by instability. In contrast, as shown in (B) in Figure 1, when the user transmits video files, since the total duration of the video file transmission is far greater than the upper limit of the interaction delay, the increase and instability of the interaction delay will only lead to the transmission rate. Changes at certain moments, but hardly affect the average transmission rate, so users hardly feel the freeze.

It is understandable that, comparing low-latency services with other services, when the interaction delay is large and/or the interaction delay is unstable, the low-latency service will be more affected and the user experience will be more affected. big.

(2) The first type of equipment, the second type of equipment

According to whether the low-latency service is running on the electronic device, the electronic device can be divided into the first type of device and the second type of device. The first type of device is an electronic device that is running a low-latency service, and the second type of device is an electronic device that is not running a low-latency service. Moreover, both the first type of device and the second type of device perform data interaction on the same channel. For the definition of the low-latency service, reference may be made to the text description in (1) Low-latency service and other services in Terminology Explanation, which will not be repeated here.

Optionally, similar to the classification of services, in some embodiments of the present application, electronic devices may be further classified into first-type devices, second-type devices, and other types of devices. Among them, the first type of equipment is electronic equipment that is running low-latency services, the second type of equipment is electronic equipment that is not running low-latency services and is running high-throughput services, and other types of equipment are neither running low-latency services. And there's also no electronics to run high-throughput business.

It is worth noting that classifying electronic devices into the first type of equipment and the second type of equipment provides a basis for the differentiated scheduling of communication resources, and giving priority to ensuring the communication resources of the first type of equipment is conducive to improving user experience; or , the electronic equipment can be classified into the first type of equipment, the second type of equipment and other types of equipment. Considering that the second type of equipment runs high-throughput services and occupies a large amount of communication resources, the second type of equipment can be given priority. Communication resources, more effectively improve the efficiency of communication resource scheduling.

As the state of the application/service session on the electronic device changes, the application/service session can be transformed from a low-latency service to other services, and similarly, it can also be transformed from other services to low-latency services. Correspondingly, the first type of equipment can be converted into the second type of equipment (other type of equipment), and the second type of equipment (other type of equipment) can be converted into the first type of equipment. The following takes the content shown in FIG. 2 and FIG. 3 as examples to introduce the conversion between the first type of equipment and the second type of equipment.

Figure 2 (A) shows the conversion between the first type of device and the second type of device from the application point of view. Figure 2 (B) shows the conversion between the first type of equipment and the second type of equipment from the perspective of service sessions.

As shown in (A) in Figure 2, when a game is running on the mobile phone 1, and the game is in the process of playing, the game is a low-latency service, that is, the mobile phone 1 is a first-class device; After the game battle of the game is over and the game body is updated, at this time, the game is a high-throughput service, that is, mobile phone 1 is a second-class device; when mobile phone 1 closes the game, and mobile phone 1 is not running low-latency services and In the case of high-throughput services, the mobile phone 1 is the second type of equipment (other type of equipment).

Correspondingly, as shown in (B) in Figure 2, when the game running on the mobile phone 1 creates a battle service session, at this time, the battle service is a low-latency service, that is, the mobile phone 1 is a first-class device; The game ends the battle service session and creates an update service session. At this time, the update service session is a high-throughput service, that is, mobile phone 1 is a second-class device; when the game on mobile phone 1 is closed, and the application on mobile phone 1 does not run For a business session of low-latency and high-throughput business, the mobile phone 1 is the second type of device (other type of device).

As shown in Figure 3, the pre-configured delay threshold of the application/service session on the device is 150 milliseconds. When the device estimates that the channel delay carrying the data of the application/service session exceeds 150 milliseconds, the device is the first type Device; when the device estimates that the channel delay of carrying the data of the application program/service session is less than or equal to 150 milliseconds, the device is the second type of device. Combining the content shown in FIG. 3 , within seconds 0 to 0.3 and after 1.6 seconds, the mobile phone 1 is a first-class device; within 0.3 seconds to 1.6 seconds, the mobile phone 1 is a first-class device.

It can be understood that, according to the requirements of the applications/service sessions running on the electronic devices, the electronic devices can be divided into the first type of devices and the second type of devices, and the differential classification of electronic devices is the differential scheduling of communication resources. provided the foundation.

(3) Wireless channel

A wireless channel refers to a channel that uses a wireless signal as a transmission carrier to transmit data. Among them, the frequency point and the bandwidth can be used to describe the wireless channel, and the frequency point and the bandwidth jointly determine the frequency range of the signal transmitted on the channel. In the P2P scenario, the available frequency bands of the wireless channel include: Industrial Scientific and Medical (ISM) frequency band and unlicensed frequency band.

In a wireless channel, the time it takes for data to be transmitted from one end to the other is called the channel delay. The user can only intuitively feel the interaction delay, where the interaction delay includes the channel delay. In a P2P scenario, there are many factors that affect the channel delay, such as the busyness of the air interface of the access device and the signal-to-noise ratio of the wireless channel. For a wireless channel, when there are multiple high-throughput services for data exchange in the channel, it can be considered that the air interface corresponding to the wireless channel is relatively busy. Moreover, for low-latency services, the more other services that transmit data on the same channel, the lower the signal-to-noise ratio of the channel.

According to whether there is a first-type device transmitting on the wireless channel, the wireless channel can be divided into a first-type channel and a second-type channel. The first type of channel is mainly used for the first type of equipment to perform data interaction, and the second type of channel is mainly used for the second type of equipment (and other types of equipment) to perform data interaction.

The first type of device may notify other devices by broadcasting the first information that the channel on which the first type of device is located is the first type of channel. The expression form of the first message may be the frequency point and bandwidth of the first type of channel, or the expression form of the first message may be the channel number specified by the communication protocol it complies, which is not limited here. The broadcasted first message may be encrypted or plaintext.

There are many ways for the first type of device to broadcast, for example, it can broadcast on a control channel, or can broadcast on an out-of-band channel, or can broadcast through short-range communication, etc., which is not limited here.

For the concepts of terms such as control channel and out-of-band channel, reference may be made to the text description in (4) Channel selection strategy and device avoidance strategy in Terminology Explanation, which will not be repeated here.

It can be understood that, by differentially dividing the wireless channels into the first type of channels and the second type of channels, a basis is provided for the differential scheduling of communication resources. Specifically, when communication resources are scarce, in order to ensure the communication resources of the first-type devices, the second-type devices in the first-type channels are switched to the second-type channels to ensure the communication resources of the first-type devices in the first-type channels. communication resources. Secondly, when other first-type devices are not in the first-type channel, the first-type device can be instructed to access the first-type channel for data interaction.

Wherein, at any moment, the communication performance of the first type of channel, such as channel delay, signal-to-noise ratio parameters, etc., need not be better than the communication performance of the second type of channel.

The following takes the content shown in FIG. 4 as an example to introduce the relationship between the channel delay and the interaction delay.

As shown in Figure 4, a WIFI connection is established between the mobile phone and the projector, and the mobile phone projects the PPT screen to the projector through the WIFI connection. The mobile phone establishes a WIFI connection with the projector at the 0th second, and starts to establish the screen projection service in response to the user's operation; at the 0.05th second, the mobile phone establishes and completes the screen projection service, and begins to request air interface resources from the projector for data transmission. ;In the 0.05th to 0.08th second, the mobile phone fails to compete for air interface resources; in the 0.08th second, the mobile phone begins to request the projector for air interface resources for the second time to transmit data; in the 0.08th to 0.11th second, the mobile phone The competition for air interface resources is successful, and data transmission starts at 0.11 seconds; from 0.24 seconds to 0.35 seconds, the channel delay of the wireless channel carrying the data is 0.24 seconds, and the projector does not receive complete data. Retransmit data; at 0.35 seconds, the mobile phone starts to retransmit data; from 0.35 seconds to 0.45 seconds, the channel delay of the wireless channel carrying the data is 0.1 seconds; at 0.45 seconds, the projector will The data is handed over to the upper-level business; at 0.46 seconds, the projector displays the data on the screen.

Obviously, for the user, the interaction delay can be directly felt as 0.46 seconds, in which the channel delay of the two data transmissions of the packet block, wherein the two channel delays are 0.24 seconds and 0.1 seconds respectively.

(4) Channel selection strategy, device avoidance strategy

In this embodiment of the present application, the channel selection strategy is the strategy on which the electronic device selects a wireless channel for access.

Among them, according to whether the electronic device can determine whether the device itself is the first type of device when selecting a wireless channel for access, it can be divided into two situations:

First, when the electronic device cannot determine whether the device itself is the first type of device when selecting a wireless channel for access, the channel selection strategy includes: the electronic device selects an appropriate wireless channel for access according to the communication protocol complied with during interaction.

Second, when the electronic device is able to determine whether the device itself is a first-class device when selecting a wireless channel for access, the channel selection strategy includes: when the electronic device is a first-class device and there is currently a first-class channel , the electronic device accesses the first-type channel; when the electronic device is a first-type device and there are multiple first-type channels, the electronic device randomly selects a first-type channel to access, or The electronic device selects the first type of channel access with the least number of devices, or the electronic device selects the first type of channel access with the highest channel signal-to-noise ratio, or the electronic device selects the first type of channel access with the highest channel received power, etc. ; When the electronic device is a first-class device and there is currently no first-class channel, the electronic device randomly selects a second-class channel to access, or the electronic device selects the second-class channel with the least number of devices to access. , or the electronic device selects the second type of channel access with the highest channel signal-to-noise ratio, or the electronic device selects the wireless channel access with the highest channel received power. When the electronic device is a second-type device, the first-type channel or the second-type channel can be selected for access.

When a device prepares to access a wireless channel, it can learn whether there is a first-type channel that can be accessed in the current environment in various ways. For example, the device can listen to the first message in a variety of ways, such as a control channel and an out-of-band channel. , to determine whether there is a channel of the first type, and the frequency point and bandwidth of the channel of the first type, which are not limited here.

Wherein, the control channel can have many different forms according to the different communication protocols complied with when the device data interacts. For example, the control channel can be the wireless radio used for broadcasting specified by the Apple Wireless Direct Link (AWDL) protocol. The channel, the wireless channel for broadcasting specified by the neighbor awareness network (neighborawareness network, NAN) protocol, the wireless channel for broadcasting specified by the short-range communication protocol such as Bluetooth, etc., are not limited herein.

The device may estimate the number of devices in different channels in various ways. For example, the device may estimate the number of devices in different channels through clear channel assessment (CCA), which is not limited herein.

The device avoidance policy is the policy on which the first type of device requests the second type of device (other type of device) to reduce the occupation of communication resources when the experience parameter of the low-latency service on the first type of device does not meet the experience parameter threshold. When a first-type device performs data interaction on the first-type channel, and the experience parameter of the low-latency service running on the device is less than or equal to the experience parameter threshold, it will send one or more second-type devices to one or more devices according to the device avoidance policy. The device (other type of device) initiates a communication resource release request, so that one or more second type of device (other type of device) reduces the occupation of communication resources to ensure the communication resources of the first type of device.

The experience parameter of the low-latency service is used to directly or indirectly reflect the service quality of the low-latency service. The experience parameter can be many kinds of parameters, for example, the experience parameter can be a requirement for channel delay; or the experience parameter can be a QoE parameter, etc.; or the experience parameter can be a KPI parameter, etc., which are not limited here.

Wherein, the device avoidance strategy may include: the device avoidance strategy may be that the first type of device randomly selects a second type of device (or other type of device), and sends a communication resource release request to the second type of device (or other type of device); or , the device avoidance strategy can be that the first type of device estimates the order of the communication resources occupied by the devices in the current wireless channel according to the request to send protocol (request to send, RTS) or the permission to send protocol (cleartosend, CTS), and according to the order of occupied communication resources Send a communication resource release request to the device in turn; or, the device avoidance strategy may be that the first type of device broadcasts the communication resource release request to all devices, and the second type of device (other type of device) after receiving the communication resource release request, can Respond to the communication resource release request.

In some embodiments of the present application, when a first-type device sends a communication resource release request, it may not be able to know whether other devices are first-type devices or second-type devices (other-type devices). In this case, when the first type of device receives the communication resource release request, it will not respond to the communication resource release request; correspondingly, in this case, the second type of device (other device) receives the communication resource release request may respond to a communication resource release request.

The response made by the second type of device (other type of device) after receiving the communication resource release request may be: switching the wireless channel carrying the data interaction. And according to the difference of the second type of device (other types of devices), different channel switching methods can be adopted. For example, when the second type of device is two mobile phones (mobile phone A and mobile phone B, respectively) that are transferring a large number of files through Bluetooth One of the mobile phone A, after receiving the communication resource release request, the mobile phone A negotiates with the mobile phone B, and selects other channels for data transmission according to the complied Bluetooth protocol; for another example, when the second type of device is router D, Mobile phone C is downloading video through router D. When router D receives the communication resource release request, it can select other channels to work in combination with the WIFI protocol complied with by router D, and notify mobile phone C of the new channel, so it is not limited here. .

Optionally, in some embodiments of the present application, after receiving the communication resource release request, the second type of device does not have a switchable channel or the communication quality of the switched channel is poor. , the response may be to reduce the communication rate. For example, when the service running on the second type of device is a video service, the communication rate can be reduced by reducing the frame rate or the bit rate.

It is worth noting that when the electronic devices are divided into the first type of equipment, the second type of equipment and other types of equipment, other types of equipment may not respond after receiving the communication resource release request for the first time; When the number of times of receiving the communication resource release request exceeds the threshold, the response may include switching channels, reducing the communication rate, and the like.

It can be understood that when the electronic devices are divided into the first type of equipment and the second type of equipment, the second type of equipment occupies more communication resources and has a higher tolerance for the interaction delay caused by switching channels, which can allow the second type of equipment. Class I devices release communication resources by switching channels or reducing communication rates, thereby ensuring user experience of low-latency services on Class I devices.

It is understandable that when the electronic equipment is divided into the first type of equipment, the second type of equipment, and other types of equipment, considering that other types of equipment occupy less communication resources, only the second type of equipment can switch channels or reduce the communication rate. In order to release communication resources, the user experience of low-latency services on the first type of equipment can be guaranteed; or, considering the complexity of the device avoidance strategy, the second type of equipment and other types of equipment can be switched to switch channels or reduce the communication rate to The communication resources are released, thereby ensuring the user experience of the low-latency service on the first type of equipment.

The following takes the content shown in FIG. 5 as an example to introduce the relationship between experience parameters, experience parameter thresholds, and device conversion.

Combining the content shown in Figure 3 and Figure 5, the pre-configured delay threshold of the application/service session on the device is 150 milliseconds, the pre-configured experience parameter of the application/service session on the device is the channel delay, and the experience parameter threshold is 200 milliseconds. Based on the content shown in Figure 3, when the device estimates that the channel delay carrying the data of the application/service session exceeds 200 milliseconds, it is considered that the low-latency service experience parameter on the device does not meet the experience parameter threshold. Therefore, from 0.5 seconds to 1.2 seconds, mobile phone 1 is a first-class device, and the low-latency service experience parameters on mobile phone 1 do not meet the experience parameter threshold, and mobile phone 1 will send communication resources to other devices according to the device avoidance policy. release request.

The following briefly introduces the P2P scenarios involved in this application, and several communication resource cooperation methods involved in this application.

In a P2P scenario, a variety of different types of electronic devices may perform data exchange on wireless channels in the same or similar frequency bands according to different communication protocols. In this case, whether it is spectrum leakage of electronic devices on adjacent frequency bands or competition for air interface resources by electronic devices on the same wireless channel, it will inevitably lead to increased and unstable device interaction delay. For low-latency services, the increase and instability of the interaction delay will greatly deteriorate the user experience.

As shown in FIG. 6 , in the P2P scenario, the devices that are using communication resources may include computers, wearable smart devices, mobile terminals, smart home devices, and the like. Considering that the protocols complied with when different devices interact with each other can be different, there can be multiple channels in the space. For a certain frequency band, such as frequency band 1, there may be multiple channels on frequency band 1, which carry data interaction of different electronic devices. In the ISM frequency band and the unlicensed frequency band, there may be multiple channels with overlapping frequency ranges on frequency band 1, which may further aggravate the increase and instability of the interaction delay between electronic devices.

It can be understood that it is necessary to reduce the interaction delay of devices and reduce the instability of interaction delay by reasonably scheduling communication resources.

As shown in Figure 7, the router provides channel 1 and channel 2 for devices to access. Channel 1 can be the channel provided by the router in the 5G frequency band, and channel 2 can be the channel provided by the router in the 2.4G frequency band. Before device 2 is connected to the router, device 1 exchanges data with other devices and on channel 1. When device 2 is connected to the router, it can listen to the transmission opportunity (TXOP) to determine that there are more devices carrying data interaction on channel 1 and fewer devices carrying data interaction on channel 2, so channel 2 is selected to connect to the router. enter.

However, it takes a certain amount of time to detect a suitable wireless channel resource through TXOP or other dedicated detection frames, and to select a wireless channel for access after the detection is completed. Obviously, considering the time variability of the wireless channel, when the device selects the channel according to the detection result, the parameters such as the channel delay of the selected wireless channel and the degree of congestion of the air interface resources will change, which does not guarantee that the device can access the channel. After the wireless channel, the communication resources of the device can be guaranteed.

As shown in Figure 8, there are two working routers in the P2P scenario, namely router 1 and router 2. Among them, router 1 provides channel 2 to the electronic device for data exchange, and router 2 provides channel 3 to the electronic device. for data interaction. According to the regulations of the WIFI protocol, the router can work on channel 1 to channel 13, and the frequency band ranges between channel 1, channel 2, and channel 3 partially overlap. Device 1 accesses router 1 through channel 2. Since channel 2 and channel 1 have partial spectrum overlap, device 1 transmits data on channel 2, which is greatly interfered by router 2, and can switch to channel 1, which is less interfered by router 2, for data exchange.

When the wireless channel carrying data interaction on the electronic device is interfered, the electronic device can select other channels with less interference for data interaction. However, the operation of switching the channel itself will cause a sharp increase in the interaction delay, which is likely to deteriorate the user experience.

The two wireless channel selection and access methods designed in the present application described above do not first take into account that different applications/service sessions on the electronic device have different tolerances for interaction delays. Obviously, selecting the same resource scheduling method for different applications/service sessions cannot effectively guarantee the user's experience of using low-latency services. Secondly, when the communication performance of the wireless channel carrying electronic device data interaction, such as channel delay and other parameters, deteriorates, the operation of actively switching the channel itself will further aggravate the interaction delay.

Since the traditional communication protocol does not take into account the difference in channel communication quality requirements between low-latency services and other services, when the channel communication quality can meet the needs of other services but cannot meet the needs of low-latency services, it will not actively switch. channel. In this case, for the user, the low-latency service is always available but not usable, which will also deteriorate the user's experience.

In view of the above existing problems, the present application provides a communication resource cooperation method and an electronic device.

As shown in Figure 9, similar to that shown in Figure 7, the router provides channel 1 and channel 2 for devices to access. Channel 1 can be the channel provided by the router in the 5G frequency band, and channel 2 can be the channel provided by the router in the 2.4G frequency band. Initially, both device 1 and device 2 perform data interaction on channel 1, and device 1 is a second-type device and device 2 is a first-type device. When the experience parameter of the low-latency service on the device 2 does not meet the experience parameter threshold, a communication resource release request is sent to the device 1. After receiving the communication resource release request, device 1 can choose to switch to channel 2 for data interaction. Since the device 1 gives up communication resources, the interaction delay of the device 2 is reduced, and the experience of the user using the device 2 is improved. Secondly, because the device 1 is a second type of device, it is not sensitive to the increase of interaction delay and instability caused by channel switching, so that the user who uses the device 1 hardly feels stuck.

With reference to the contents shown in FIGS. 7 to 9 , it can be understood that the communication resource collaboration method provided by the present application firstly divides the application program/service session into two groups according to the requirements of the application program/service session on the electronic device for the interaction delay. Low-latency services and other services. Secondly, based on the classification of the application program/service session, the corresponding devices running the application program/service session are divided into a first-type device and a second-type device. Further, after the devices are classified, the communication resources of the low-latency service on the first type of devices are guaranteed through differentiated scheduling of communication resources, which can greatly improve the user experience.

The following describes the communication resource cooperation method provided by the present application.

As shown in FIG. 14 , the communication resource cooperation method provided by the present application may include:

S1401: In response to the establishment of the service session, the electronic device prepares to access the channel.

Specifically, in response to the user starting the application on the electronic device, or in response to the application creating the service session on the electronic device, the electronic device begins to prepare for data interaction, and prepares to select an appropriate communication resource to carry the data interaction.

The service session may be an HTTP session, an RTP session, etc., which is not limited herein.

Wherein, when the electronic device selects an appropriate communication resource, the range of the wireless channel that the electronic device can select is also different according to the different protocols that the application program/service session complies with when establishing communication. For example, when an electronic device is connected via Bluetooth 4.0, the electronic device can select multiple wireless channels in the frequency band range of 2.4GHz to 2.483GHz. And according to the specific version of the agreement and the different regions, the frequency band range and the number of wireless channels are also different.

Optionally, in some embodiments of the present application, when the electronic device starts an application or the application creates a service session, the electronic device may directly designate the application as a low-latency service or the service session as a low-latency service. That is, when a software developer develops an application, the application/service session can be pre-configured as a low-latency service or other service. For the concept of the low-latency service, reference may be made to the text descriptions in Interpretation of medium-low-latency services and other services (1), which will not be repeated here.

Step S1402 is executed.

S1402: The electronic device listens for the first message on the control channel.

Specifically, when the electronic device prepares to access the channel, a certain period of time may be allocated for listening to the first message on the control channel, so as to determine whether there is a channel of the first type in the current space.

The process of preparing the electronic device to access the channel may occur during the process of the electronic device transitioning from the idle state to the connected state, or the process of the electronic device transitioning from the sleep state to the connected state.

The length of time allocated by the electronic device to listen to the first message may be related to the period T during which the electronic device broadcasts the first message on the control channel in step S1406. For example, the electronic device may allocate a time of 1.2T for monitoring the first message on the control channel, which is not limited herein.

For the concepts of terms such as control channel, out-of-band channel, and first message, please refer to the text descriptions in (3) Wireless channel and (4) Channel selection strategy and device avoidance strategy in the term explanation, which will not be repeated here.

Step S1403 is executed.

S1403: The electronic device selects a channel to access according to the channel selection policy.

Specifically, after the electronic device in step S1402 listens to the first message, it can determine whether the first type of channel currently exists. The electronic device selects a channel to access based on whether there is currently a first-type channel and a channel selection policy preconfigured on the electronic device.

In some embodiments of the present application, when an electronic device selects a channel to access, if it is temporarily unable to determine whether the electronic device itself is a first-type device or a second-type device according to the existing parameters, it can be based on the communication protocol it complies. Select the appropriate channel to access. After the electronic device selects the channel to access, it is determined that a low-latency service is running on the electronic device, that is, when the electronic device is a first-type device, it can switch to the first-type channel.

In some embodiments of the present application, after the electronic device is converted from a second-type device to a first-type device, and after step S1402 is executed, it is determined that there is a first-type channel, and the first type of channel for switching can be selected according to a channel selection strategy class channel.

In some embodiments of the present application, after the electronic device is converted from the second type of device to the first type of device, when the experience parameter of the low-latency service on the electronic device does not meet the experience parameter threshold, and after step S1402 is performed, determine There is a first type of channel, and the first type of channel to be switched can be selected according to the channel selection strategy.

Among them, the concepts of the first type of equipment, the second type of equipment, the first type of channel, and the channel selection strategy can refer to (2) the first type of channel, the second type of equipment, (3) the wireless channel, (4) the channel in the term explanation The text description in the selection policy and device avoidance policy will not be repeated here.

Step S1404 is executed.

S1404: When the electronic device is the first type of device and the electronic device is on the first type of channel, determine whether the experience parameter of the low-latency service on the electronic device meets the experience parameter threshold.

Specifically, after the electronic device accesses the wireless channel and before step S1404 is performed, it can be determined whether the application/service session running on the electronic device is a low-latency service, that is, whether the electronic device is a first-type device. And, the electronic device can determine whether it is currently on the first type of channel. When the electronic device is the first type of device, one or more low-latency services may be running on the device, and the electronic device determines whether the experience parameters of all current low-latency services meet the experience parameter threshold.

The electronic device can obtain the experience parameter thresholds of all current low-latency services, and when the experience parameter is the channel delay, the electronic device can determine the channel delay of the current channel, and then determine whether the experience parameter meets the experience parameter threshold. For example, the electronic device can obtain the experience parameters of the low-latency service based on the mobile communication module 150, the wireless communication module 160, etc. as shown in FIG. 10; or, the electronic device can obtain the low-latency service based on the network card driver as shown in FIG. 12 experience parameters. Or, after the low-latency service determines whether the experience parameter satisfies the experience parameter, it notifies the electronic device of the result of whether it satisfies. For example, when the experience parameter is KPI and QoE, after the low-latency service determines the relationship between the experience parameter and the experience parameter threshold, it informs the electronic device of the result.

When the experience parameter of any low-latency service does not meet the experience parameter threshold, step S1405 is performed;

When the respective experience parameters of all the low-latency services on the device meet the experience parameter threshold, step S1408 is performed.

Optionally, in some embodiments of the present application, for a certain first-type device, when the experience parameter does not meet the experience parameter threshold and there are currently multiple first-type channels, it can switch to other first-type channels. After that, step S1404 is executed again. Among them, when switching to other first-type channels, you can switch to the first-type channel with the largest number of first-type devices, or you can switch to the first-type channel with the highest signal-to-noise ratio, or you can switch to the first-type channel with the highest received power class channel.

Among them, the concepts of how the device determines that the application/service session running on the device is a low-latency service, experience parameters, experience parameter thresholds and other terms can refer to (1) low-latency services, other services in the term explanation, (4) The text descriptions in the channel selection strategy and the device avoidance strategy will not be repeated here.

S1405: Whether there is a second-type device performing data exchange on the first-type channel.

Specifically, according to different classification standards of low-latency services, there are different ways to determine whether there is a second type of device on the channel where the electronic device is located for data exchange. When there is a second type of device on the channel where the electronic device is located to perform data interaction, step S1406 is performed; when there is no second type of device on the channel where the electronic device is located to perform data interaction, step S1407 is performed.

For example, when the low-latency service is pre-configured by the application, the electronic device can use TXOP detection, radio detection, RTS/CTS and other technologies to obtain the field used to represent the application in the header of the data packet in the channel to determine the current Whether there is a second type of device in the channel that is interacting with data.

For another example, when the division standard of low-latency services is related to channel delay or interaction delay, the electronic device can access whether other electronic devices are the first type of devices through the short-range communication service; or the electronic device records in the control channel broadcast No. A device that receives a message, and compares it with the device that is performing data exchange on the current channel to determine whether there is a second type of device in the current channel, which is not limited here.

S1406: The first type of device sends a communication resource release request to the second type of device according to the device avoidance policy.

Specifically, the first-type device sends a communication resource release request to one or more second-type devices (or second-type devices and other types of devices) in the first-type channel where the first-type device is located according to the device avoidance policy . Alternatively, the first type of device broadcasts the communication resource release request to all the devices in the channel where the first type of device is located according to the device avoidance policy.

For the concepts of terms such as device avoidance strategy and communication resource release request, please refer to the text description in (4) Channel selection strategy and device avoidance strategy in Terminology Explanation, which will not be repeated here.

Step S1404 is executed.

It can be understood that by initiating a communication resource release request to other devices, other devices switch channels or reduce the communication rate, freeing up communication resources for the electronic devices where the low-latency service is located, thereby improving the user's ability to use the low-latency service. Use experience.

In the following, in conjunction with the contents shown in FIG. 15 and FIG. 16 , how the first type of device sends a communication resource release request according to the device avoidance policy is exemplarily introduced.

As shown in Figure 15, a WIFI connection is established between the mobile phone 1 and the projector, and a Bluetooth connection is established between the mobile phone 2 and the mobile phone 3. The mobile phone 1 and the projector are running a projection service, and the projection service is preconfigured as a low-latency service, that is, the mobile phone 1 is a first-class device. The mobile phone 2 and the mobile phone 3 run a file transfer service, and the file transfer service is pre-configured as a high-throughput service, that is, the mobile phone 2 is a second-class device. And the channel used for data interaction between mobile phone 1 and the projector is the same as the channel used for data interaction between mobile phone 2 and mobile phone 3 .

When the experience parameter of the low-latency service on the mobile phone 1 does not meet the experience parameter threshold, it prepares to send a communication resource release request to the mobile phone 2 according to the locally preconfigured device avoidance policy. At this time, the mobile phone 1 can establish a short-range communication service with the mobile phone 2 through technologies such as radio sensing technology, such as HiLink connection, Bluetooth connection, etc., and send a communication resource release request to the mobile phone 2 based on the short-range communication service.

Similar to the content shown in Figure 15, the mobile phone 1 shown in Figure 16 is the first type of device, the mobile phone 2 is the second type of device, and both the mobile phone 1 and the mobile phone 2 are connected to the router through WIFI.

As shown in (A) of Figure 16, when the experience parameter of the low-latency service on the mobile phone 1 does not meet the experience parameter threshold, it can send a communication resource release request to the router and the frequency of the channel 1 that carries the data interaction of the screen casting service of the mobile phone 1. point and bandwidth. The router can forward the communication resource release request and the frequency point and bandwidth used to indicate the channel 1 to multiple devices including the mobile phone 2 according to the device avoidance policy preconfigured on the router.

Multiple devices including the mobile phone 2 receive the communication resource release request and the frequency and bandwidth used to indicate the wireless channel 1 . Since the mobile phone 2 is the second type of device that performs data interaction on the wireless channel 1, the mobile phone 2 will choose to switch the Bluetooth channel.

As shown in (B) of FIG. 16 , when the experience parameter of the low-latency service on the mobile phone 1 does not meet the experience parameter threshold, it can be determined to send a communication resource release request to the mobile phone 2 according to the pre-configured local device avoidance policy. The mobile phone 1 can send the communication resource release request and the identifier of the mobile phone 2 to the router through WIFI. After the router obtains the communication resource release request, it can forward the communication resource release request to the router according to the identifier of the mobile phone 2 .

S1407: The first type of electronic device widens the first type of channel.

Specifically, when there is no second-type device in the first-type channel where the first-type device is located, the first-type device can expand the first-type channel to ensure the communication resources of the low-latency service.

Widening the first-type channel may include: changing the frequency and bandwidth of the first-type channel, such as increasing the bandwidth; This is not limited.

Wherein, setting up a new channel may include: for the router, the channel may be re-divided from the available frequency spectrum, and the channel corresponding to the new frequency point and bandwidth may be selected for access.

Step S1404 is executed.

S1408: The first-type device broadcasts the first message on the control channel, announcing that the channel is the first-type channel.

Specifically, when the experience parameter meets the experience parameter threshold, the application on the electronic device may broadcast a first message on the control channel to inform other devices that the channel indicated by the first message is the first type of channel.

Optionally, in some embodiments of the present application, the electronic device may also notify other devices through short-range communication or other communication protocols that the channel on which the electronic device is located is the first type of channel.

Taking the scenario shown in FIG. 17 where multiple electronic devices interact as an example, and in conjunction with the communication resource cooperation method shown in FIG. 14 , the communication resource cooperation method in the embodiment of the present application is exemplarily described:

As shown in FIG. 17 , there are multiple electronic devices that can interact with each other in a certain scene, including: mobile phone 1 , mobile phone 2 , and mobile phone 3 . The mobile phone 1, the mobile phone 2, and the mobile phone 3 respectively establish wireless connections with other devices and perform data exchange. In order to explain this scenario more easily, it is considered that the wireless connections established by mobile phone 1, mobile phone 2, and mobile phone 3 can all be carried on channel 1 or channel 2. Channel 1 and channel 2 have different frequencies and the same channel delay.

In this scenario, application A runs on mobile phone 1, and application A is pre-configured as a low-latency service; application B runs on mobile phone 2, and application B is configured with a delay threshold of 180 milliseconds, That is, when the estimated channel delay is greater than 180 milliseconds, the application is a low-latency service; when the estimated channel delay is less than 180 milliseconds, the application is other services; there is application C running on mobile phone 3, and application C is configured as High throughput business. The experience parameter threshold of application A is estimated to be 165 milliseconds of channel delay, and the experience parameter threshold of application B is 200 milliseconds.

And, in combination with the estimated channel delay shown in Figure 17, it can be known that: in the 0th to 0.4th second, the mobile phone 2 is the second type of device; in the 0.4th to 1.0th second, the mobile phone 2 is the first type of device device; after 1.0 seconds, mobile phone 2 is a second-class device. Mobile phone 1 has always been the first type of device, and mobile phone 3 has always been the second type of device.

In the following, in conjunction with the steps in the communication resource cooperation method shown in FIG. 14 , the flow of the mobile phone 2 implementing the communication resource cooperation method provided by the present application in the scenario shown in FIG. 17 is exemplarily introduced.

Before the 0th second, both mobile phone 1 and mobile phone 3 have access to channel 1 for data exchange, and mobile phone 1 is the first type device and mobile phone 3 is the second type device; from the 0th second to the 0.3th second, the mobile phone 1 Broadcast the first message to notify other devices that the channel is the first type of channel.

Corresponding to step S1401: at the 0th second, the user starts the application B on the mobile phone 2 to prepare to access the channel.

Corresponding to step S1402: in the 0th to 0.3th second, the mobile phone 2 detects the first message sent by the mobile phone 1, and learns that the channel 1 in the current environment is the first type channel, and the channel 2 is the second type channel.

Corresponding to step S1403: within the 0th second to 0.3rd second, and after monitoring the first message, the mobile phone 2 selects the access channel 1. From 0.3 seconds to 0.4 seconds, because the estimated channel delay is greater than the experience parameter threshold of application A, mobile phone 1 sends communication resource release request 2 to mobile phone 2 and communication resource release request 1 to mobile phone 3. And in response to the communication resource release request 2, the mobile phone 2 switches to access the channel 2; in response to the communication resource release request 1, the mobile phone 3 reduces the communication rate.

Corresponding to step S1406: in the second to 0.4 seconds, since the estimated channel delay is greater than the channel delay threshold of application B, the mobile phone 2 is converted from the second type of device to the first type of device. Since the mobile phone 2 is transformed into the first type of equipment, the mobile phone 2 selects the first type of channel access, that is, selects the channel 1 to access.

From 0.45 seconds to 0.8 seconds, after mobile phone 2 accesses channel 1, the estimated channel delay is still greater than the experience parameter threshold of application B, so a communication resource release request is sent to mobile phone 3. After receiving the communication resource release request 3, the mobile phone 3 switches to the channel 2.

It can be understood that, by implementing the communication resource coordination method provided by this application, it not only ensures that the service experience statically configured as a low-latency service is maintained at a high level, and secondly, it ensures that the The business experience does not fall below a lower level. The communication resource cooperation method provided by the present application achieves a dynamic balance among maximizing the utilization rate of communication resources, maximizing the user experience of the low-latency service, minimizing the interaction delay and instability.

It can be understood that, by implementing the communication resource cooperation method provided by the present application, through the dynamic and differentiated allocation of communication resources, for low-latency services, it is largely avoided due to the shortage of channel resources and frequent channels. The interaction delay increases and becomes unstable due to handover and other reasons, which effectively guarantees the communication resources of devices running low-latency services.

As used in the above embodiments, the term "when" may be interpreted to mean "if" or "after" or "in response to determining..." or "in response to detecting..." depending on the context. Similarly, depending on the context, the phrases "in determining..." or "if detecting (the stated condition or event)" can be interpreted to mean "if determining..." or "in response to determining..." or "on detecting (the stated condition or event)" or "in response to the detection of (the stated condition or event)".
