Some embodiments of the invention will now be described in detail with reference to the accompanying drawings. In the case where there is no conflict between the embodiments, the following embodiments and features in the embodiments may be combined with each other. In addition, the sequence of steps in the method embodiments described below is only an example and is not strictly limited.

Fig. 1 is a communication network according to an embodiment of the present invention. As shown in fig. 1, the communication Network may include a server providing a target service, a 5G Core Network (5 GC) and a radio access Network (Radio Access Network RAN) and a terminal device using the target service.

The 5GC has a general core network structure, and will not be described in detail here. A network access device, such as a 5G base station (the next Generation Node B, gNB) or the like, may be deployed in the RAN.

In the communication network shown in fig. 1, before the target service is normally provided, the network access device may determine a resource scheduling policy, and execute the policy to allocate air interface resources corresponding to the target service, that is, allocate air interface resources required for using the target service for the terminal device. Meanwhile, a plurality of services can be registered in the communication network, and then the total air interface resources of the network access device can be respectively allocated to the plurality of services, so that all or part of the total air interface resources of the network access device can be allocated to the target service. In the normal providing process of the target service, the terminal device and the server can both generate a data packet to be transmitted, and the terminal device and the network access device can transmit the data packet to be transmitted to the other party by using the air interface resources which are allocated to the terminal device and correspond to the target service, so that the user can normally use the target service.

Alternatively, the target service may include XR service mentioned in the background, an autopilot service, a control service of intelligent manufacturing equipment, and the like. For these services, the communication network may alternatively be deployed as a 5G private network within an area to provide the services described above within that area. Optionally, the target service may also include a video on demand service, a live video service, and so on. The live video in the video live broadcast service can be a sports event, a remote medical video, a remote teaching video and the like.

Optionally, the quality of service indicator may specifically include a transmission delay and/or a transmission bandwidth, and may also include a mean subjective opinion score (Mean Opinion Score, abbreviated as MOS) to reflect. The MOS can be calculated according to the transmission delay and/or the transmission bandwidth. For services involving video, such as XR services, video on demand services, live video services, etc., as described above, the quality of service may also include video quality.

Different services may also be provided with different preset quality indicators. For example, XR services may be provided with smaller transmission delays and larger transmission bandwidths; video on demand and live services can be provided with a larger transmission bandwidth; the autopilot service and the control service may be provided with a smaller transmission delay. And for the preset quality index of the service, it should be noted that, when the same service is used, different terminal devices may also have different service qualities for the target service, for example, different requirements for transmission delay and transmission bandwidth. Alternatively, the quality of service of the terminal device may be related to the priority of the user using the terminal device. Optionally, the network access device may obtain a preset quality indicator of the terminal device for the service in response to a service usage request sent by the terminal device.

For the terminal device using the target service and the server providing the target service, optionally, the terminal device corresponding to the XR service may be a mobile terminal device with application programs such as VR, AR, MR, etc. installed, and may also be a wearable VR device, AR device, MR device, etc. The terminal equipment corresponding to the live broadcast service can be mobile terminal equipment such as a mobile phone, a tablet computer, a notebook computer and the like. The server providing the service can store streaming media data such as XR video, live video and the like. The terminal device corresponding to the control service may be intelligent manufacturing equipment on a pipeline, such as an intelligent mechanical arm, and the server for providing the service may store various status data collected and reported by the intelligent manufacturing equipment, and may further have the capability of generating a control instruction according to the various status data, where the control instruction is used to control the working mode of the intelligent manufacturing equipment. The terminal device corresponding to the autopilot service may be a vehicle-mounted terminal device. The server providing the service can store various vehicle state data collected and reported by the vehicle-mounted terminal equipment, and the server also has the capability of determining control instructions according to the respective vehicle state data, wherein the control instructions are used for enabling the vehicle to realize automatic driving.

In practice, the network access device may determine the resource scheduling policy by using the methods provided in the embodiments of the present invention, and perform air interface resource allocation by executing the resource scheduling policy, so that when the terminal device uses the target service by using the allocated air interface resource, the service quality of the target service is ensured. It should be noted that, in the following embodiments of the present invention, reference to guaranteeing the quality of service refers to guaranteeing the quality of service of the terminal device, that is, the terminal device may use the target service when the quality of service is satisfied.

Based on the above description, fig. 2 is a flowchart of a method for scheduling air interface resources according to an embodiment of the present invention. The air interface resource scheduling method provided by the embodiment of the invention can be executed by the network access equipment in the communication network. As shown in fig. 2, the method may include the steps of:

s101, determining an initial resource scheduling strategy according to a channel quality index, wherein the channel quality index corresponds to a wireless channel between terminal equipment and network access equipment.

In response to the terminal device accessing the communication network, the network access device may acquire a channel quality indicator fed back by the terminal device, and determine an initial resource scheduling policy according to the channel quality indicator. The channel quality index may be considered as a physical layer index, which is used to reflect the communication quality of the wireless channel between the terminal device and the network access device. Optionally, a preset algorithm may be deployed in the network access device, and the channel quality indicator may be used as an input parameter of the preset algorithm to determine an initial resource scheduling policy.

Optionally, the channel quality indicator may specifically include a channel quality indicator (Channel Quality Indicator, CQI for short). The terminal device may comprehensively refer to various indexes such as the received power of its own reference signal (Reference Signal Receiving Power, RSRP for short), the strength indication of the received signal (Received Signal Strength Indicator, RSSI for short), the received quality of the reference signal (Reference Signal Received Quality, RSPQ for short), the signal-to-interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR for short) and the like to calculate the CQI value.

Alternatively, the preset algorithm for determining the initial resource scheduling policy may include any one of Round Robin (RR) scheduling algorithm, proportional fair (Proportional Fairness, PF) scheduling algorithm, and maximum carrier to interference ratio (MaxC/I) algorithm. Optionally, the determined initial Resource scheduling policy may include an initial modulation and coding policy (Modulation and Coding Scheme, abbreviated MCS), a number of radio Resource Blocks (RBs), and air interface resources allocated for the terminal device. And the basic rule of the above-mentioned preset algorithm for determining the resource scheduling policy may be that the higher the channel quality is, the more data blocks are allocated to the terminal device, and the more air interface resources are allocated to the terminal device.

S102, determining an estimated service quality index of a target service used by the terminal equipment, wherein the air interface resources required by the target service are allocated by the network access equipment to execute an initial resource scheduling strategy.

Further, the network access device determines an estimated quality of service indicator of the target service used by the terminal device, that is, the network access device may perform indicator estimation. This estimation process can be understood as: the network access device estimates what the quality of service index of the target service is when the terminal device uses the target service by means of the allocated air interface resources if it performs the initial resource scheduling policy in step S101 for the terminal device itself. That is, in step S102, the network access device does not actually execute the initial resource scheduling policy and does not actually allocate the air interface resource to the terminal device, but assumes an estimation of the quality of service of the target service after the initial resource scheduling policy is executed.

It should be noted that, as described in the embodiment shown in fig. 1, the quality of service indicator may include a transmission delay and/or a transmission bandwidth, and may also include MOS and video quality. It can be seen that, compared with the channel quality index in step S101, the estimated quality index can more intuitively reflect the service quality of the target service, i.e. can more truly reflect the use experience of the user, so that the estimated service quality index is an application layer index.

For the estimation of the quality of service indicator, optionally, the network access device may obtain a historical quality of service indicator and determine an estimated quality of service indicator based on the historical quality of service indicator, the quality of service indicator comprising a mean opinion value.

Specifically, in an optional prediction manner, the network access device may perform prediction of the quality of service index at the first time. Meanwhile, the network access equipment can also acquire the historical service quality index of the target service. The historical service quality index is the service quality index of the target service when the terminal equipment uses the target service by using the air interface resources distributed by the historical resource scheduling strategy. And the network access device determines the aforementioned historical resource scheduling policy at a second time instant that is adjacent to and earlier than the first time instant. Because the two moments are adjacent, the probability of sudden change of the service quality is small, and therefore, the network access equipment can directly determine the historical service quality index as the estimated service quality index.

In another optional pre-estimating mode, the network access device may also obtain a locally stored scheduling policy service condition list while estimating the service quality index at the first time, where the list records a historical resource scheduling policy determined by the network access device at a historical time and a historical service quality index of the target service when the terminal device uses the target service with the air interface resource allocated by the historical resource scheduling policy. Wherein the historical time comprises at least one time earlier than the first time. If the network access device queries in the list that the resource scheduling policy determined at the third moment is the same as the initial resource scheduling policy in step S101, the historical quality of service index corresponding to the third moment may be directly determined as the estimated quality index. Wherein the third time is one of the historical times.

S103, determining whether to adjust the initial resource scheduling strategy according to the difference between the estimated service quality index and the preset quality index so as to obtain the target resource scheduling strategy.

Further, the network access device may determine whether to adjust the initial resource scheduling policy according to a difference between the estimated quality of service index and the preset quality index. And specific adjustment procedures of the scheduling resource policy can be referred to as descriptions in the following embodiments. The items included in the target resource scheduling policy are the same as those in the initial resource scheduling policy, the items included in the preset quality index are also the same as those in the estimated quality index, and the related content can be referred to the related description in the embodiment shown in fig. 1, which is not repeated here.

S104, executing a target resource scheduling strategy to allocate air interface resources required by using the target service for the terminal equipment.

Finally, the network access device may execute the target resource scheduling policy to allocate air interface resources required for using the target service for the terminal device. The terminal device can use the allocated air interface resource to transmit the pending data packet generated when using the target service. Similarly, the network access device may also feed back the pending packets generated by the server to the terminal device by using the air interface resources allocated to the target service.

In this embodiment, the network access device may determine the initial resource scheduling policy according to the physical layer index, i.e., the channel quality index. And then determining that if the initial resource scheduling policy is executed to allocate air interface resources for the terminal equipment, when the terminal equipment uses the target service by means of the allocated air interface resources, the service quality index of the target service is estimated, and the estimated service quality index is an estimated application layer index. Further, whether to adjust the initial resource scheduling policy is determined by comparing the estimated quality of service index with the preset quality index, so as to obtain the target resource scheduling policy. Finally, the network access device executes the target resource scheduling strategy to realize allocation of the air interface resources.

In the process, the physical layer index and the application layer index are sequentially used in the process of obtaining the target resource scheduling strategy, wherein the application layer index can reflect the service quality more directly, i.e. the use experience of a user can be reflected more truly. The combined use of the multiple layers of indexes can enable the determined target resource scheduling strategy to be more reasonable, namely, after the resource is allocated according to the target resource scheduling strategy, when the terminal equipment uses the target service by means of the allocated air interface resources, the quality of the target service can be ensured, and the use experience of a user can be met.

In addition, for the beneficial effects that can be achieved by comprehensively using the physical layer index and the application layer index to allocate the air interface resources, the following description can be also combined to understand:

in practice, the physical layer index may be generated by the terminal device in the form of a data packet and sent to the network access device, but the real-time performance of the physical layer index obtained by the network access device is poor because the physical layer index received by the network access device cannot accurately reflect the quality of the current wireless channel due to the fact that the transmission delay of the data packet and the process that the network access device analyzes the physical layer index from the data packet are considered, and meanwhile, the network environment change is considered to be fast, more precisely, the environment change of the wireless channel between the terminal device and the network access device is fast. Thus, using physical layer indicators alone to determine a resource scheduling policy does not guarantee that the determined resource scheduling policy is suitable for the current network environment.

On the other hand, although the physical layer index can reflect the communication quality of the wireless channel, the quality of the channel cannot necessarily be directly reflected on the service quality, that is, the situation that the channel quality is good but the service quality is poor is possible to occur, so that the resource scheduling strategy determined by using the physical layer index alone cannot guarantee the service quality, that is, cannot guarantee the user experience.

In the embodiment shown in fig. 2, after the network access device obtains the initial resource scheduling policy by using the physical layer index, the network access device may further use the application layer index capable of directly reflecting the service quality to adjust the resource scheduling policy, so as to obtain the resource scheduling policy which is suitable for the current network environment and can ensure the service quality.

In the above embodiment, the network access device may determine whether to adjust the initial resource scheduling policy according to the estimated quality of service index and the preset quality index. The adjustment process of the resource scheduling policy can be described in detail in connection with the following embodiments.

Fig. 3 is a flowchart of another air interface resource scheduling method according to an embodiment of the present invention. As shown in fig. 3, the method may include the steps of:

s201, determining an initial resource scheduling strategy according to a channel quality index, wherein the channel quality index corresponds to a wireless channel between terminal equipment and network access equipment.

S202, determining the estimated service quality index of the target service used by the terminal equipment, wherein the air interface resources required by the target service are allocated by the network access equipment to execute the initial resource scheduling strategy.

The specific implementation process of step S201 to step S202 may refer to the specific description of the related steps in the embodiment shown in fig. 2, which is not repeated here.

And S203, if the estimated service quality index does not meet the preset quality index, adjusting the initial resource scheduling strategy to obtain a target resource scheduling strategy, wherein the air interface resources allocated to the terminal equipment according to the target resource scheduling strategy are more than the air interface resources allocated to the terminal equipment according to the initial resource scheduling strategy.

If the estimated quality of service index does not meet the preset quality index, the initial resource scheduling policy may be adjusted to obtain the target resource scheduling policy. The adjustment modes of the resource scheduling policy can be various, but different modes have the same adjustment purpose: more air interface resources are allocated to the terminal equipment, namely more air interface resources are allocated to the terminal equipment according to the target resource scheduling policy than air interface resources are allocated to the terminal equipment according to the initial resource scheduling policy.

And the reasons why the estimated qos index cannot meet the preset qos index due to the use of the initial resource scheduling policy may include: when the quality of the wireless channel between the terminal equipment and the network access equipment is poor, the air interface resources allocated to the terminal equipment according to the initial resource scheduling policy are less, so that the data packets to be transmitted generated by the terminal equipment cannot be transmitted in time, and the service quality cannot be guaranteed. From another point of view, allocating fewer air interface resources may also reduce the parsing capability of the terminal device for the data packet to be transmitted, where the data packet to be transmitted needs to include a small amount of useful data in order to accommodate the lower parsing capability. But a small amount of useful data is insufficient to enable the user to smoothly use the target service, i.e., the quality of service cannot be guaranteed. For the above reasons, the network access device needs to adjust the resource scheduling policy according to the adjustment purpose, so as to allocate more air interface resources to the terminal device to ensure the service quality.

As can be seen from the above description, the initial resource scheduling policy may include an initial MCS, and one alternative adjustment may be to adjust the order of the initial MCS, specifically to reduce the order of the initial MCS.

The relationship between MCS order and the number of air interface resources can also be explained as follows:

the MCS of either order specifies the amount of useful data in one Resource Element (RE for short). The higher the MCS order, the more useful data one RE contains, the less air interface resources are required to transmit the same amount of useful data, and the faster the transmission rate. The RE may specifically represent the data packet to be transmitted. Considering that the amount of useful data required by the terminal equipment is determined in the process of smoothly using the target service, more air interface resources can be allocated to the terminal equipment by reducing the MCS order, and the terminal equipment can receive a sufficient amount of useful data by using the more air interface resources.

It should be noted that the above procedure of reducing the initial MCS level is actually an iterative adjustment procedure, where the step size of reducing the MCS level may be preset, and the more stringent the service requirement on the transmission delay, the longer the step size may be set, so as to quickly reduce the MCS level to a lower level, and allocate more air interface resources to the terminal device by using the MCS with the lower level, thereby ensuring the service quality.

And according to the above description of the order, the order of the initial MCS obtained by the network access device performing step S201 is related to the channel quality, and the higher the channel quality, the higher the order of the initial MCS.

S204, if the estimated service quality index meets the preset quality index, determining the initial resource scheduling strategy as a target resource scheduling strategy.

In another case, if the estimated quality of service indicator meets the preset quality indicator, which indicates that the quality of service of the target service can be guaranteed by using the initial resource scheduling policy, the initial resource scheduling policy may be directly determined as the target resource scheduling policy.

S205, executing a target resource scheduling strategy to allocate air interface resources required by using the target service for the terminal equipment.

The specific implementation process of step S205 may refer to the specific description of the relevant steps in the embodiment shown in fig. 2, which is not repeated here.

In this embodiment, the network access device compares the estimated quality of service index with the preset quality index, and if the estimated quality of service index does not meet the preset quality index, the initial resource scheduling policy is adjusted to allocate more air interface resources for the terminal device, so that the terminal device uses more air interface resources to receive and process the data packet to be transmitted corresponding to the target service, and the quality of service is ensured. If the estimated quality of service index meets the preset quality index, the initial resource scheduling strategy can be directly executed to allocate the air interface resources. It can be seen that both the above two methods can ensure the service quality of the target service. In addition, the details of the embodiment which are not described in detail and the technical effects which can be achieved can be referred to the description of the above embodiment, and are not described herein.

As can be seen from the description in the embodiment shown in fig. 1, when a plurality of services can be registered in the communication network, the total air interface resources of the network access device need to be allocated to the plurality of services respectively, and in order to improve the usage rate of the total air interface resources, when the estimated quality of service index meets the preset quality index, optionally, the network access device may further determine whether to adjust the initial resource scheduling policy according to the degree that the estimated quality of service index exceeds the preset quality index.

Fig. 4 is a flowchart of another air interface resource scheduling method according to an embodiment of the present invention. As shown in fig. 4, the method may include the steps of:

s301, determining an initial resource scheduling strategy according to a channel quality index, wherein the channel quality index corresponds to a wireless channel between terminal equipment and network access equipment.

S302, determining an estimated service quality index of a target service used by the terminal equipment, wherein the air interface resources required by the target service are allocated by the network access equipment to execute an initial resource scheduling strategy.

The specific implementation process of step S301 to step S302 may refer to the specific description of the related steps in the embodiment shown in fig. 2, which is not repeated here.

S303, if the estimated quality of service index meets the preset quality index, determining whether to adjust the initial resource scheduling policy according to the degree that the estimated quality of service index exceeds the preset quality index so as to obtain the target resource scheduling policy, wherein the air interface resources allocated to the terminal equipment according to the target resource scheduling policy are not more than the air interface resources allocated to the terminal equipment according to the initial resource scheduling policy.

As can be seen from the description in the embodiment shown in fig. 1, the quality indicator of the target service may include a transmission delay and a transmission bandwidth, and may also include MOS. When the quality index includes a transmission delay and a transmission bandwidth, estimating the degree to which the quality index exceeds the preset quality index may comprehensively consider the degree to which the estimated transmission delay is smaller than the preset transmission delay and the degree to which the estimated transmission bandwidth is larger than the preset transmission bandwidth. When the quality index includes MOS, the estimated quality index exceeds the preset quality index, namely the estimated MOS is larger than the preset MOS.

In one case, the degree to which the estimated quality of service index exceeds the preset quality index is outside the preset range, which indicates that the terminal device may be allocated with excessive air interface resources using the initial resource scheduling policy, so that the quality of service index of the target service has far exceeded the preset quality index. However, such an excessively high quality of service index is not reflected on the user experience, for example, when the video is played smoothly, the user does not feel that the smoothness of the video is changed even if the transmission delay is further reduced and/or the transmission bandwidth is further increased. And the terminal device using the target service is allocated to excessive air interface resources, so that the terminal device using other services cannot be allocated to enough air interface resources, and therefore the service quality of other services in the communication system cannot be ensured. Therefore, if the initial resource scheduling policy is not adjusted, the above-mentioned uneven air interface resource allocation situation can be generated, so that the utilization rate of the total air interface resources of the network access device is reduced.

In order to improve this problem, if the degree to which the estimated quality of service indicator exceeds the preset quality indicator is outside the preset range, the network access device may adjust the initial resource scheduling policy for the purpose of allocating fewer air interface resources for the terminal device using the target service. I.e. the air interface resources allocated to the terminal device according to the target resource scheduling policy are less than the air interface resources allocated to the terminal device according to the initial resource scheduling policy.

In another case, if the estimated quality of service index exceeds the preset quality index by a degree within a preset range, it indicates that the quality of service of the target service can be ensured by using the initial resource scheduling policy, and the air interface resources allocated to the terminal device are not excessive, the network access device may determine the initial resource scheduling policy as the target resource scheduling policy, that is, the air interface resources allocated to the terminal device according to the target resource scheduling policy are the same as the air interface resources allocated to the terminal device according to the initial resource scheduling policy.

When the resource scheduling policy may include MCS, in combination with the description of the relationship between the MCS level and the number of air interface resources, the adjustment of the initial resource scheduling policy in the above two cases is specifically: if the degree of the estimated quality of service index exceeding the preset quality index is within the preset range, the order of the initial MCS is maintained. If the degree of the estimated quality of service index exceeding the preset quality index is out of the preset range, the order of the initial MCS is increased.

Similar to the above procedure of reducing the initial MCS level, when the MCS level is increased, the increased step size may be preset, and the more stringent the service is to the transmission delay requirement, the longer the step size may be set, so as to quickly reduce the MCS level to a lower level, and allocate more air interface resources to the terminal device by using the MCS of the lower level, thereby ensuring the service quality.

S304, executing a target resource scheduling strategy to allocate air interface resources required by using the target service for the terminal equipment.

In this embodiment, after comparing the estimated quality of service index with the preset quality index, if the estimated quality of service index exceeds the preset quality index to a small extent, the network access device may directly use the initial resource scheduling policy as the target resource scheduling policy to directly execute the policy to allocate air interface resources for the terminal device using the target service. If the estimated quality of service index exceeds the preset quality index to a small extent, the initial resource scheduling strategy can be adjusted to allocate fewer air interface resources to the terminal equipment using the target service. In this case, the saved air interface resources may be allocated to the terminal device using other services, so that the usage rate of the total air interface resources of the network access device may be improved. In addition, the details of the present embodiment, which are not described in detail, and the technical effects that can be achieved can be referred to the descriptions in the above related embodiments, and are not described herein again.

In practice, the target service may alternatively not set the upper bearer limit of the terminal device. The upper limit of the bearer is the maximum number of terminal devices using the target service on the premise of ensuring the service quality. The network access device may allocate air interface resources to the terminal device according to the method provided in the above embodiments on the premise of ensuring service quality whenever there is a terminal device that wants to use the target service.

Optionally, the target service may also set the upper bearer limit of the terminal device, and for this case, fig. 5 is a flowchart of another air interface resource scheduling method provided in the embodiment of the present invention. As shown in fig. 5, the method may include the steps of:

s401, determining an initial resource scheduling strategy according to a channel quality index, wherein the channel quality index corresponds to a wireless channel between terminal equipment and network access equipment.

S402, determining the estimated service quality index of the target service used by the terminal equipment, wherein the air interface resources required by the target service are allocated by the network access equipment for executing the initial resource scheduling strategy.

S403, if the estimated service quality index meets the preset quality index, determining the initial resource scheduling strategy as a target resource scheduling strategy.

The specific implementation process of step S401 to step S403 may refer to the specific description of the related steps in the embodiment shown in fig. 3, which is not repeated herein.

S404, determining the estimated number of terminal devices capable of using the target service by means of the air interface resources, wherein the air interface resources required by the terminal devices for using the target service are allocated by the network access device for executing the target resource scheduling policy.

After the network access device determines the initial resource scheduling policy as the target resource scheduling policy, the network access device can further determine the user capacity corresponding to the target resource scheduling policy, that is, determine that the network access device executes the target resource scheduling policy, and then use the estimated number of the terminal devices of the target service on the premise of ensuring the service quality. Similar to step S402, in step S404, the network access device does not actually execute the target resource scheduling policy and does not actually allocate air interface resources to the terminal device, but after executing the hypothetical target resource scheduling policy, can provide a target service for ensuring service quality for how many terminal devices.

For the estimation of the estimated number, optionally, the network access device may know the air interface resources used for providing the target service in the total air interface resources, and by executing the target resource scheduling policy, the network access device may also know how many air interface resources need to be allocated to each terminal device using the target service on the premise of ensuring the service quality. The estimated quantity can be calculated by using the two air interface resources. Alternatively, in a simplest manner, the ratio of the two may be determined as an estimated number.

S405, executing a target resource scheduling strategy according to the difference between the estimated number and the upper bearing limit so as to allocate air interface resources for the estimated number of terminal devices or the upper bearing limit of the terminal devices.

Finally, the network access device can realize allocation of air interface resources according to the difference between the estimated quantity and the bearing upper limit corresponding to the target service. Meanwhile, the network access device can also utilize the air interface resource allocated to the target service to feed back the data packet to be transmitted generated by the server to the terminal device. When the target service is registered in the communication network, the network access device may acquire the bearer upper limit set by the target service.

Specifically, the difference between the estimated number and the upper bearer limit is in two cases:

under the condition that the estimated number is smaller than the bearing upper limit, the estimated number indicates that the air interface resources are allocated according to the target resource scheduling strategy, so that the estimated number of terminal equipment can use the target service on the premise of ensuring the service quality. Therefore, when the estimated number of terminal devices send the target service use request to the network access device, the network access device can respond to the target service use request to execute the target resource scheduling policy so as to allocate air interface resources for the estimated number of terminal devices respectively. At this time, the estimated number of terminal devices can use the target service while ensuring the quality of service.

In this case, when other terminal devices than the estimated number of terminal devices also send the target service use request to the network access device, the network access device may establish a heartbeat connection between itself and other terminal devices in response to the request, but does not allocate air interface resources for the other terminal devices so as not to affect the quality of service of the estimated number of terminal devices that are using the target service. Meanwhile, the network access device can also send overload prompt information to other terminal devices for establishing heartbeat connection so as to prompt the current target service to reach the upper limit of bearing.

As can be seen from the above description, the resource scheduling policy is dynamically adjusted, so when the target resource scheduling policy obtained by executing the next adjustment period can ensure the service quality of the other terminal device, the network access device can allocate air interface resources for the other terminal device, so that the other terminal device can also use the target service.

In another case, the estimated number is greater than the upper limit of the bearer, and when the terminal device with the upper limit of the bearer sends the target service use request to the network access device, the network access device can respond to the target service use request to allocate air interface resources for the terminal device with the upper limit of the bearer. The terminal device bearing the upper limit can use the target service while guaranteeing the quality of service.

In this case, when other terminal devices except the terminal device bearing the upper limit also send a target service use request to the network access device, the network access device may respond to the request to establish heartbeat connection between itself and other terminal devices, but does not allocate air interface resources for the other terminal devices so as to ensure the upper limit of the bearing of the target service.

In this embodiment, when the quality of service index meets the estimated quality index, the network access device may further evaluate the user capacity corresponding to the initial resource scheduling policy, and control the number of terminal devices that need to allocate air interface resources according to the user capacity, so as to ensure that all the terminal devices using the target service can meet the quality of service. That is, in this embodiment, the network access device performs air interface resource scheduling after comprehensively considering the user capacity and the service quality. More terminal devices use the target service while ensuring the service quality, namely, the balance between the service quality and the user capacity is realized. In addition, the details of the present embodiment, which are not described in detail, and the technical effects that can be achieved can be referred to the descriptions in the above related embodiments, and are not described herein again. It can be seen that, in the above-described resource scheduling process,

Optionally, the scheduling of the air interface resources by the network access device is performed periodically and iteratively, and thus the process of the embodiment shown in fig. 5 may also be understood in connection with fig. 6.

For the case that the estimated quality of service index in the embodiment illustrated in fig. 5 satisfies the preset quality index and the estimated number is greater than the upper limit of the bearer, optionally, the network access device may further reduce the order of the initial MCS in the initial resource scheduling policy to obtain the target resource scheduling policy, and allocate air interface resources for the terminal device by executing the policy. The above procedure can also be understood in connection with fig. 7. In the above process, the terminal equipment is allocated to more air interface resources due to the reduction of the order, so that the possibility of the occurrence of the cliff type reduction of the service quality caused by the sudden degradation of the wireless channel environment can be reduced.

And as can be seen from the description in the embodiment shown in fig. 3, the lower the MCS level, the more air interface resources are allocated to the terminal device. This results in lower MCS orders, and fewer terminal devices that the target service can carry, due to the limited allocation of network access devices to air interface resources that provide the target service. Therefore, the user capacity is also considered in the process of reducing the initial MCS order, so that more terminal devices can use the target service as much as possible while ensuring the service quality. Namely, the initial MCS is reduced to a proper order, so that the balance between the service quality and the user capacity is realized, the situation that the number of terminal equipment is small due to the excessively low MCS order is improved, and the utilization rate of air interface resources can be ensured.

While the above embodiments have described the allocation flow of the air interface resources, but the target service used by the terminal device is not limited, when the target service is specifically the above-mentioned XR service, fig. 8 is a flow chart of still another air interface resource scheduling method according to the embodiment of the present invention. The implementation subject of this embodiment is still a network access device in a communication network. As shown in fig. 8, the method may include the steps of:

Fig. 10 is a flowchart of still another air interface resource scheduling method according to an embodiment of the present invention when the target service is specifically the above-mentioned autopilot service. The implementation subject of this embodiment is still a network access device in a communication network. As shown in fig. 10, the method may include the steps of:

s701, determining an initial resource scheduling policy according to a channel quality index, the channel quality index corresponding to a wireless channel between the intelligent manufacturing equipment and the network access device.

S702, determining an estimated service quality index of an automatic driving service used by the vehicle-mounted terminal equipment, wherein the air interface resources required by the automatic driving service are allocated by the network access equipment through executing an initial resource scheduling strategy.

S703, determining whether to adjust the initial resource scheduling strategy according to the difference between the estimated service quality index and the preset quality index corresponding to the control service, so as to obtain the target resource scheduling strategy.

S704, executing a target resource scheduling strategy to allocate air interface resources required by using the automatic driving service for the vehicle-mounted terminal equipment.

In this embodiment, the network access device can allocate air interface resources for the vehicle-mounted terminal device using the control service by executing the above steps. Alternatively, the in-vehicle terminal device may include an in-vehicle video device, an in-vehicle navigation system, a touch screen, an external camera, an automobile burglar alarm, and the like.

The following describes a specific procedure of allocating air resources by a network access device deployed in a communication network, taking a 5G communication network providing VR services as an example. The following procedure can also be understood in connection with fig. 11.

The VR service is pre-registered in the 5G communication network and is also provided with an upper bearer limit of 1000. The network access device in the 5G communication network is specifically a gNB.

The head-mounted VR device may feed back a CQI value of the wireless channel to the gNB in real time, and when the head-mounted VR device may also send a VR service use request to the gNB, the gNB may determine, at time T1, a resource scheduling policy 1 according to the CQI value, where the order of the MCS in the policy is 6 order. Alternatively, there may be at least one head-mounted VR device, and different devices may have corresponding resource scheduling policies 1.

The following procedure for allocating air interface resources may be described for any head-mounted VR device:

at this time, in one case, the gNB may estimate that if the resource scheduling policy 1 is used, the quality of service index of the head-mounted VR device is 30Mbps of the transmission bandwidth, and the transmission delay is 50ms. Because the preset quality index of the equipment is that the transmission bandwidth is 40Mbps and the transmission delay is 40ms, if the estimated service quality index does not meet the preset quality index, the gNB can reduce the order of the MCS to 4 so as to obtain the resource scheduling strategy 2. The gNB may execute this resource scheduling policy 2 to allocate more air interface resources to the head-mounted VR device.

At the time T2 after T1, the gNB may further determine a quality of service indicator corresponding to the resource scheduling policy 2, and if the indicator does not meet the preset quality indicator, further reduce the order of the MCS until the quality of service of the head-mounted VR device meets the preset quality indicator.

Alternatively, the gNB may estimate that if resource scheduling policy 1 is used, the quality of service indicator of the head-mounted VR device is 40Mbps for transmission bandwidth and 40ms for transmission delay. At this time, if the estimated quality of service index happens to meet the preset quality index, the gNB may determine to use the resource scheduling policy 1, further estimate the user capacity corresponding to the resource scheduling policy 1, that is, the estimated number, and determine, according to the relationship between the estimated number and the upper limit 1000 of the VR service, to provide VR service meeting the preset quality index for the corresponding number of head-mounted VR devices. Specific procedures can be found in the related descriptions in the related embodiments described above.

In yet another case, the gNB may estimate that if resource scheduling policy 1 is used, the quality of service index of the head-mounted VR device is 70Mbps of transmission bandwidth and 10ms of transmission delay. At this time, if the estimated quality of service index is far beyond the preset quality index, the gNB may increase the MCS order to 6 to obtain the resource scheduling policy 3. The gNB may execute this resource scheduling policy 3 to allocate fewer air interface resources to the head-mounted VR device. And other saved air interface resources can be distributed to terminal equipment using other services of the communication system, so that the utilization rate of the air interface resources in the communication system is improved.

For the target resource scheduling policy obtained in each case, the gNB can allocate corresponding air interface resources for the head-mounted VR device by executing the target resource scheduling policy, so that the head-mounted VR device can meet the preset quality index of the head-mounted VR device and more devices can use the VR service.

Optionally, the above procedure is also applicable to various XR services such as AR, MR, and the specific procedure will not be described again.

The following describes a specific process of air interface resource allocation by a network access device deployed in a communication network, taking a 5G communication network for providing a control service for controlling an intelligent robot arm on a line as an example. The following procedure can also be understood in connection with fig. 12.

When the terminal device is specifically an intelligent mechanical arm on a production line, since the mechanical arm does not have a video playing function, different from the head-mounted VR device, a preset quality index of the mechanical arm includes a transmission delay. The specific air interface resource allocation procedure is similar to that described in the embodiment shown in fig. 11, and will not be described here again. Optionally, the mechanical arms may be different types of mechanical arms on different pipelines, and the different types of mechanical arms may also have different preset quality indexes.

The following describes a specific procedure of air interface resource allocation by a network access device deployed in a communication network, taking a 5G communication network providing an autopilot service as an example. The following procedure can also be understood in connection with fig. 13.

When the terminal device is specifically a vehicle-mounted video device, similar to the above-mentioned head-mounted VR device, the preset quality index of the vehicle-mounted video device includes a transmission delay and a transmission bandwidth. The specific air interface resource allocation procedure is similar to that described in the embodiment shown in fig. 11, and will not be described here again.

When the terminal device is specifically a vehicle navigation system, the vehicle navigation system does not have a video playing function, so that the preset quality index of the vehicle navigation system comprises transmission delay. The specific air interface resource allocation procedure is similar to that described in the embodiment shown in fig. 11, and will not be described here again.

In addition to the above two cases, optionally, for other vehicle-mounted terminal devices, the vehicle-mounted terminal devices may have different preset quality indexes, for example, may include a transmission delay or a transmission bandwidth separately, or may include both a transmission delay and a transmission bandwidth, and at this time, the allocation of air interface resources may also be performed according to the procedure in the embodiment shown in fig. 11.
