All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The words "if", as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination" or "in response to a recognition", depending on the context. Similarly, the phrases "if determined" or "if identified (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when identified (a stated condition or event)" or "in response to an identification (a stated condition or event)", depending on the context.

Without further limitation, an element defined by the phrase "comprising a … …" does not exclude the presence of additional like elements in a commodity or system comprising the element.

Some embodiments of the invention may be described in detail below with reference to the following figures. The features of the embodiments and examples described below may be combined with each other without conflict between the embodiments. In addition, the sequence of steps in the embodiments of the methods described below is merely 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 (5G Core Network, abbreviated as 5 GC), a Radio Access Network (Radio Access Network, abbreviated as RAN), and a terminal device installing a target application providing the target service.

Among them, the 5GC has a general core network structure, and is not described in detail here. The RAN may include network access equipment, such as a 5G base station (gNB).

In the communication network shown in fig. 1, in the process of providing the target service, both the terminal device and the server may generate a to-be-transmitted data packet, and the to-be-transmitted data packet generated by any party may be transmitted to the other party by using the RAN and the 5GC, so that the user can normally use the target service. In addition, in the process of providing the target service, no matter whether the data packet to be transmitted is generated by the terminal device or the server, the data packet needs to use an air interface resource when being transmitted between the RAN and the terminal device, and at this time, the air interface resource can be scheduled in a manner provided by each embodiment in the present disclosure, so that the data packet can be transmitted according to the transmission requirement, thereby ensuring the quality of the target service. Optionally, the transmission requirements may include transmission delay and/or transmission bandwidth, etc.

Based on the above description, the following may also describe the uplink and downlink transmission processes of the data packet respectively:

when data is uplink, the terminal device generates a data packet to be transmitted, and the network access device in the RAN sends the data packet to be transmitted to the 5GC by using the allocated air interface resource, and then the 5GC forwards the data packet to the server. It should be noted that, strictly speaking, the to-be-transmitted data package may be considered to be generated by the target application program, because the to-be-transmitted data package corresponds to the target service. But for the sake of simplicity of description, the description of the terminal device generating the data package to be transmitted may be continued later.

When data is downlink, a server generates a data packet to be transmitted, the data packet to be transmitted can be transmitted to the RAN from the 5GC, and a network access device in the RAN can receive the data packet to be transmitted and then forward the data packet to be transmitted to a terminal device by using allocated air interface resources.

Alternatively, the target service may be XR, autopilot, etc. as mentioned in the background, but also video on demand, live video, etc. The live video in the video live broadcast service can be sports events, telemedicine videos, remote teaching videos and the like. And the data packets corresponding to different services all have different transmission requirements. Specifically, the XR service has strict requirements on the transmission delay and transmission bandwidth of the data packet, the video on demand and live broadcast service has strict requirements on the transmission bandwidth of the data packet, and the autopilot service has strict requirements on the transmission delay of the data packet. In the XR service, video on demand, video live broadcast and other services, the data packets can be continuously generated and transmitted in a streaming mode.

For the terminal device and the server, the terminal device corresponding to the XR service may be a VR device, an AR device, an MR device, or other mobile terminal devices. The terminal device corresponding to the live broadcast service can be a mobile terminal device such as a mobile phone, a tablet computer and a notebook computer. Multimedia data such as XR video, live video, etc. may be stored in the server providing the above services. The terminal device corresponding to the automatic driving service may be a vehicle-mounted terminal device. The server providing the service can store various state data of the vehicle, which are collected and reported by the vehicle-mounted terminal equipment, and the server also has the capability of determining a control instruction according to the various state data, wherein the control instruction is used for enabling the vehicle to realize automatic driving.

As can be seen from the above description, during the uplink and downlink transmission of the data packet, the whole communication network may include multiple roles:

and the generating party is used for generating the data packet to be transmitted. In the communication network shown in fig. 1, the generator may be a terminal device or a server.

And the transmission side is used for receiving or sending the data packet to be transmitted by using the air interface resource. In the communication network shown in fig. 1, the transmitting party may be a network access device in the RAN.

And the receiver is used for finally receiving the data packet to be transmitted generated by the generator. In the communication network shown in fig. 1, the receiving side may also be a terminal device or a server.

Alternatively, the generating party may be embodied as a generating device, the receiving party may be embodied as a receiving device, and the transmitting party may be embodied as a network access device located between the generating device and the receiving device. Fig. 2 is a schematic structural diagram of another communication network according to an embodiment of the present invention. The network may specifically include a generating device, a receiving device, and a network access device. Both the generating device and the receiving device may provide the target service. The network access device may be located in the RAN.

The working process of the communication network can be described as follows:

the generation device may generate the to-be-transmitted data packet corresponding to the target service. The network access device can acquire the transmission performance parameters which need to be satisfied by the data packet to be transmitted, and can also acquire the hardware information of the terminal device which can be used as a generating device or a receiving device in the communication network. Then, the network access device may also determine an air interface resource scheduling policy corresponding to the data packet to be transmitted according to the multidimensional information, that is, the transmission performance parameter index and the hardware information, and allocate a certain air interface resource according to the air interface resource scheduling policy. The network access device can receive or send the data packet to be transmitted by using the air interface resource. Finally, the data package to be transmitted generated by the generating device is received or transmitted through the network access device, and the data package to be transmitted can be received by the receiving device.

According to the above-mentioned process, a unidirectional transmission of data packet is completed. In practice, each data packet generated by the generating device may be transmitted as described above.

The air interface resource is specifically used for transmitting or receiving the data packet to be transmitted and is related to the transmission direction of the data packet. Specifically, when the data packet is transmitted in the uplink, the network access device receives the to-be-transmitted data packet by using the allocated air interface resource. And when the data packet is transmitted in a downlink manner, the network access equipment transmits the data packet to be transmitted by using the allocated air interface resource. The specific process of uplink and downlink transmission of the data packet to be transmitted can also be referred to the description in the following related embodiments.

Alternatively, the target service may be various services mentioned above. When the target service is specifically an XR service, the data packet to be transmitted may be a multimedia data packet generated in the process of providing the XR service, such as VR video, AR image, and so on.

Optionally, the transmission performance parameter of the data packet to be transmitted is a requirement to be met for transmitting the data packet, and may specifically include at least one of a transmission delay, a transmission bandwidth, and a size of the data packet to be transmitted. The transmission delay and the transmission bandwidth of the data packet are matched with the type of the target service, the transmission bandwidth and the delay are the main basis for determining the air interface resource scheduling policy, and the size of the data packet, that is, the size of the data volume in the data packet, is the secondary basis for determining the air interface resource scheduling policy.

Optionally, the hardware information of the terminal device may include at least one of a model of the terminal device, a signal strength, a number of the terminal device, and remaining air interface resources that may be allocated by the network access device. It should be noted that in practice, a plurality of terminal devices may access the same network access device, and the number of the terminal devices in the hardware information is actually the total number of all the terminal devices accessing the same network access device, instead of at least one terminal device generating the to-be-transmitted data packet.

The Signal Strength of the generating device may be comprehensively determined according to index parameters such as Reference Signal Receiving Power (RSRP), received Signal Strength Indicator (RSSI), reference Signal Received Quality (RSPQ), signal to Interference plus Noise Ratio (SINR), and the like.

The air interface Resource scheduling policy determined by the network access device may specifically include at least one of a level of a Modulation and Coding Scheme (MCS) and a number of radio Resource Blocks (RBs). In addition, optionally, the air interface resource scheduling policy may further include a control instruction, where the instruction is used to control the generating device and/or the receiving device to be in the power saving mode and the duration of the power saving mode.

The relationship between the transmission performance index parameter, the hardware information, and the air interface resource scheduling policy may be understood as follows: the smaller the transmission delay, the larger the transmission bandwidth and the larger the data packet, the stronger the signal strength and the smaller the number of the terminal equipment, the more the number of RBs in the air interface resource scheduling policy, the higher the MCS level, and the shorter the duration of the equipment in the power saving mode.

In this embodiment, for a to-be-transmitted data packet generated by a generating device in a communication network, a network access device in the communication network may obtain a transmission performance index parameter of the to-be-transmitted data packet, and may also obtain hardware information of a terminal device serving as the generating device or a receiving device. Then, the network access device may determine an air interface resource scheduling policy corresponding to the to-be-transmitted data packet by using the information of each dimension, and the network access device may allocate air interface resources according to the scheduling policy, and receive or transmit the to-be-transmitted data packet by using the allocated air interface resources.

Therefore, in the process of scheduling the air interface resources, the network access device may refer to the hardware information of the terminal device and also refer to the transmission performance index parameter of the data packet to be transmitted, that is, the network access device may simultaneously sense the transmission requirement and the hardware information of the data packet to be transmitted, and perform the air interface resource scheduling based on the sensing requirement and the hardware information. The scheduling mode can ensure the rationality of air interface resource scheduling, ensure the utilization rate of air interface resources, and also ensure the transmission performance of the data packet to be transmitted, namely the service quality of the target service.

Fig. 3 is a schematic structural diagram of another communication network according to an embodiment of the present invention. On the basis of the system shown in fig. 2, the network access device may specifically include a scheduling component and a first communication component.

The scheduling component in the network access device may obtain the transmission performance index parameter of the data packet to be transmitted and the hardware information of the terminal device, and determine an air interface resource scheduling policy corresponding to the data packet to be transmitted according to the transmission performance index parameter and the hardware information. I.e. the scheduling component is adapted to sense the transmission requirements of the data packets to be transmitted to further determine the scheduling policy. The manner of obtaining the transmission performance parameter index is related to the transmission direction of the data packet, and the specific obtaining manner may also refer to the related description in the embodiment shown in fig. 4.

After the scheduling component determines the air interface resource scheduling policy, the air interface resource may be allocated to the first communication component according to the scheduling policy, so that the first communication component receives or sends the to-be-transmitted data packet by using the allocated air interface resource. The first communication component is also related to the transmission mode of the data packet, wherein the first communication component is used for receiving or sending the data packet to be transmitted.

Optionally, the Protocol stack architecture supported by the first communication component may include, in sequence from top to bottom, a Radio Resource Control (RRC) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Media Access Control (MAC) layer, and a Physical Port (PHY) layer.

The scheduling component may determine, from an application layer above the RRC layer, an air interface resource scheduling policy that meets the transmission requirement, and then each layer in the protocol stack may further configure according to the air interface resource scheduling policy determined by the scheduling component, so as to obtain the allocated air interface resource.

In this embodiment, the network access device may specifically include a scheduling component having a transmission requirement sensing capability and a first communication component. Through the perception of the transmission performance index parameters, the scheduling component can determine a more reasonable air interface resource scheduling strategy, ensure the utilization rate of air interface resources, and ensure the transmission performance of the data packet to be transmitted, namely ensure the service quality of the target service by using the strategy. Meanwhile, the scheduling component may determine an air interface resource scheduling policy from an application layer above the RRC layer, so as to implement allocation of air interface resources for each layer in a protocol stack supported by the first communication component, that is, implement cross-layer scheduling of air interface resources. In addition, the contents that are not described in detail in this embodiment and the technical effects that can be achieved also refer to the related description in the embodiment shown in fig. 2, and are not described again here.

The communication network shown in fig. 1 may be further modified to fig. 4 based on a network access device comprising a scheduling component and a first communication component in the embodiment shown in fig. 3. Fig. 4 is a schematic structural diagram of another communication network according to an embodiment of the present invention. As shown in fig. 4, a server provides a target service and accesses 5GC, a terminal device installs a target application providing the target service, and the terminal device accesses RAN and can communicate with a network access device. The terminal device may specifically include: a scheduling interface of the target application program and a data packet processing component.

In the uplink transmission process of the data packet, that is, the generating device is a terminal device and the receiving device is a server, at this time, the data packet processing component in the terminal device may obtain the to-be-transmitted data packet generated by the target application program in the terminal device by using the scheduling interface. The data packet to be transmitted is also associated with a transmission performance index to be met. In response to the acquisition of the data packet, the data packet processing component may further acquire a transmission performance index parameter corresponding to the data packet to be transmitted.

Then, the scheduling component in the network access device may obtain the transmission performance index parameter by using the communication connection between itself and the data packet processing component, and further determine an air interface resource scheduling policy corresponding to the data packet to be transmitted based on the index parameter and the hardware information of the terminal device. Because the connection between the scheduling component and the data packet processing component is opened, the perception of the scheduling component on the transmission requirement of the data packet can be realized by means of the connection between the scheduling component and the data packet processing component, and therefore an air interface resource scheduling strategy which is more appropriate and can ensure the service quality is obtained.

Finally, the first communication component in the network access device may receive the to-be-transmitted data packet generated by the terminal device by using the air interface resource allocated according to the air interface resource scheduling policy. The pending data package may be further transmitted by the first communication component to the 5GC and finally to a server providing the target service.

Optionally, the terminal device may further include a second communication component, configured to send the to-be-transmitted data packet to the first communication component in the network access device. The second communication component may implement sending of the to-be-transmitted data packet by using the air interface resource allocated according to the air interface resource scheduling policy. Therefore, the air interface resource corresponding to the air interface resource scheduling policy determined by the scheduling component can be used by the two communication components when transmitting the data packet to be transmitted.

For the uplink transmission process of the data packet, after the scheduling component determines the air interface resource scheduling policy, optionally, the data packet processing component may also sense the air interface resource scheduling policy according to the communication connection between itself and the scheduling component. The data packet processing component can also determine the processing mode of the data packet to be transmitted according to the perceived air interface resource scheduling strategy. In practice, the air interface resources available for scheduling by the scheduling component may be sufficient or tight, and therefore, the processing manner may optionally include packaging or unpacking. The processing result of the to-be-transmitted data packet output by the data packet processing component may be further sent to the first communication component by the second communication component, and an air interface resource corresponding to the air interface resource scheduling policy needs to be used in the transmission process.

Specifically, if the air interface resource corresponding to the air interface resource scheduling policy does not match the data volume of the to-be-transmitted data packet, it indicates that it may not be possible to guarantee the transmission performance requirement of the to-be-transmitted data packet by directly using the allocated air interface resource to perform uplink transmission on the to-be-transmitted data packet without processing the to-be-transmitted data packet.

When the available air interface resources for allocation are relatively tight, the mismatch between the air interface resources and the data volume may occur, that is, even if the air interface resources are scheduled according to the transmission performance index parameters of the to-be-transmitted data packet, the air interface resources allocated to the second communication component are relatively few, at this time, for the data packet with a relatively strict and/or large transmission performance requirement, the data packet processing component may unpack the to-be-transmitted data packet according to the air interface resource scheduling policy, and the second communication component respectively transmits the split data packets by using the allocated air interface resources.

And when the available air interface resources are sufficient, the air interface resources allocated by the second communication component are sufficient, and the data packet processing component can directly send the data packet to be transmitted. Optionally, because the second communication component has sufficient air interface resources, the data packet processing component may further perform packet processing on the multiple to-be-transmitted data packets, and finally, the second communication component transmits the processing result using the allocated air interface resources. Because the data packets to be transmitted can be multimedia data with higher generation speed, even if a plurality of data packets to be transmitted are packaged and then transmitted together, the service quality is not influenced.

In this embodiment, in the uplink transmission process of the data packet, the terminal device may directly obtain the data packet to be transmitted and the transmission performance index parameter associated with the data packet by using its own scheduling interface. Then, on one hand, the scheduling component in the network access device can sense the transmission performance index parameter of the data packet to be transmitted by using the communication connection between the scheduling component and the data packet processing component, so as to determine a more reasonable air interface resource scheduling strategy and ensure the utilization rate of the air interface resource. On the other hand, after the scheduling component determines the air interface resource scheduling policy, the data packet processing component may also sense the air interface resource scheduling policy by using the communication connection between itself and the scheduling component, and determine whether to package or unpack the data packet to be transmitted according to the scheduling policy. The result of the packing or unpacking can be sent to the first communication component by the second communication component by using the air interface resource corresponding to the air interface scheduling resource, and finally reaches the server.

It can be seen that, in this embodiment, with the aid of the communication connection made between the data packet processing component and the scheduling component, the scheduling component may sense the transmission requirement of the data packet to be transmitted, and the data packet processing component may also sense whether the air interface resource allocated according to the air interface resource scheduling policy is sufficient, and mutual sensing between the two parties can ensure that the scheduling policy is more reasonable, ensure the utilization rate of the air interface resource, and also can meet the transmission requirement of the data packet, that is, can ensure the target quality of service. In addition, the content that is not described in detail in this embodiment and the technical effect that can be achieved may also refer to the related description in the embodiment shown in fig. 2, and are not described again here.

Continuing to support the communication network shown in fig. 4, for the downlink transmission process of the data packet, that is, the generating device is a server and the receiving device is a terminal device, at this time, the data packet to be transmitted is generated by the server, and then the terminal device can obtain the transmission performance index parameter associated with the data packet to be transmitted by means of the scheduling interface and the communication connection between itself and the server. And the data packet processing component in the terminal equipment is acquired by the scheduling interface. Then, the scheduling component in the network access device may obtain the transmission performance index parameter by using the communication connection between itself and the data packet processing component in the terminal device, and further determine the corresponding air interface resource scheduling policy based on the index parameter and the hardware information of the terminal device. The data packet to be transmitted generated by the server may also reach the network access device via the 5GC, and then, the first communication component in the network access device may further forward the data packet to be transmitted by using the air interface resource allocated according to the air interface resource scheduling policy, so that the data packet finally reaches the terminal device.

It should be noted that, in the downlink transmission process of the data packet, the data packet to be transmitted is transmitted to the network access device by the server, and the scheduling component determines, according to the transmission performance index parameter, that there is no strict time sequence between the two processes of the air interface resource scheduling policy.

Optionally, the terminal device further includes a second communication component, which may receive the to-be-transmitted data packet sent by the first communication component, and further forward the to-be-transmitted data packet to the data packet processing component in the terminal device. Similarly, when the data packet to be transmitted is transmitted between the two communication components, the air interface resource corresponding to the air interface resource scheduling policy is used.

For the downlink transmission process of the data packet, after the data packet to be transmitted is received by the second communication component, optionally, the data packet processing component may also comprehensively consider the processing capability of itself and the size of the data packet to be transmitted, and determine whether to unpack or package the data packet to be transmitted, so as to obtain a processing result. Finally, the terminal device can also decode and display the processing result, so that the terminal device can successfully provide the target service for the user.

Optionally, if the to-be-transmitted data packet is larger and the processing capability of the terminal device is lower, the data packet processing component may unpack the to-be-transmitted data packet generated by the server. If the data package to be transmitted is small and the processing capacity of the terminal device is high, the data package processing component can package a plurality of data packages to be transmitted generated by the server.

In this embodiment, in the downlink transmission process of the data packet, the data packet processing component in the terminal device may obtain, by means of the communication connection between the data packet processing component and the server, the transmission performance index parameter associated with the data packet to be transmitted. Then, the scheduling component in the network access device can sense the transmission performance index parameter by using the communication connection between the scheduling component and the data packet processing component, so that an air interface resource scheduling strategy which is more reasonable and can meet the transmission requirement of the data packet is determined, and the target service quality is finally ensured. In addition, the content that is not described in detail in this embodiment and the technical effect that can be achieved may also refer to the related description in the embodiment shown in fig. 2, and are not described again here.

The following takes a 5G communication network providing AR services as an example, and describes a specific operation procedure of the communication network provided in each of the above embodiments.

The AR application program on the mobile terminal equipment can call a collection component on the mobile terminal equipment to collect the environmental video where the user is located, and sends the environmental video to a server providing the AR service in a data packet mode, so that the server adds corresponding enhancement data based on the collected environmental video to obtain the AR video, and the AR video can also be fed back to the AR application program of the mobile terminal equipment in the data packet mode.

Assuming that the user is located in a certain scenic spot, the environmental video collected by the AR application is the video of the scenic spot, and the enhancement data added in the video by the server may be the introduction information of the scenic spot.

Based on the above description, the environment video corresponding to the AR application collected by the mobile terminal device may be continuously transmitted to the server in the form of multimedia data, that is, the mobile terminal device may continuously generate a plurality of data packets to be transmitted as the generating device, and continuously transmit the data packets to the server, that is, the receiving device. The following may describe an uplink transmission process of any to-be-transmitted data packet:

the data packet processing component in the mobile terminal device may generate the to-be-transmitted data packet and the transmission performance index associated with the data packet, namely, the transmission delay, the transmission bandwidth and the data packet size, by using the scheduling interface AR application of the AR application. Then, the scheduling component in the gNB in the communication network may sense the transmission performance index parameter by using the communication connection between itself and the data packet processing component, and further determine an air interface resource scheduling policy corresponding to the data packet to be transmitted based on the index parameter and the hardware information of the mobile terminal device. By means of the sensing capability of the scheduling component to the transmission performance index parameters, the air interface resource scheduling strategy is more reasonable. The hardware information of the mobile terminal device may include: the number of mobile terminal devices accessing the same gNB in the network, the signal strength of the mobile terminal device generating the data packet to be transmitted, and the like.

After the scheduling component determines the air interface resource scheduling policy, the data packet processing component can also sense the air interface resource scheduling policy according to the communication connection between the data packet processing component and the scheduling component. If the air interface resources corresponding to the scheduling policy are less, and the size of the to-be-transmitted data packet is larger due to the stronger shooting capability of the mobile terminal device, the data packet processing component may unpack the to-be-transmitted data packet, and the second communication component in the mobile terminal device may transmit the unpacked data packet to the first communication component in the gNB using the allocated air interface resources, respectively. By means of the sensing capability of the data packet processing component to the air interface resources, whether the allocated air interface resources are sufficient or not can be determined, and the data packet to be transmitted is processed, so that the processing result of the data packet to be transmitted can still be transmitted according to the transmission performance index parameter.

Further, the first communication component in the gNB may further transmit the unpack result to the 5GC, and finally to the server providing the target service. The uplink transmission process of the data packet is completed according to the above process. And the sensing capability of the scheduling component and the data packet processing component can ensure that the scheduling strategy is more reasonable, and the transmission requirement of the data packet can be met, namely the target service quality can be ensured.

The above process can also be understood in conjunction with (a) in fig. 5.

After the server generates the AR video, the AR video may also be continuously transmitted to the mobile terminal device in the form of multimedia data, that is, the server as the generating device may continuously generate a plurality of data packets to be transmitted, and continuously transmit the data packets to the mobile terminal device, that is, the receiving device, thereby realizing normal provision of the AR service. The following may describe the downlink transmission process of any to-be-transmitted data packet:

the data packet processing component in the mobile terminal device can obtain the transmission performance index associated with the data packet to be transmitted by means of the scheduling interface according to the communication connection between the mobile terminal device and the server. Then, the scheduling component in the gNB may obtain the transmission performance index parameter by using the communication connection between itself and the data packet processing component in the mobile terminal device, and further determine the corresponding air interface resource scheduling policy based on the index parameter and the hardware information of the mobile terminal device.

The data packet to be transmitted generated by the server may also reach the gbb via the 5GC, and then, the first communication component in the gbb may further forward the data packet to be transmitted by using the air interface resource allocated according to the air interface resource scheduling policy, so that the data packet finally reaches the second communication component in the mobile terminal device.

The second communication component may further forward the pending data packet to a data packet processing component in the mobile terminal device. If the processing capacity of the mobile terminal device is strong and the size of the data package to be transmitted is moderate, the data package processing component can also package the data package to be transmitted, namely, the data package to be transmitted generated by the server is packaged to obtain a processing result. The mobile terminal device may present the processing result, so that the mobile terminal device successfully provides the target service for the user.

The above process can also be understood in conjunction with (b) in fig. 5.

Optionally, the above process is also applicable to various XR services such as VR, MR, etc., and the detailed description is omitted.

The scheduling mode can ensure the reasonability of air interface resource scheduling while ensuring the transmission performance of the data packet to be transmitted. In addition, because the data packet to be transmitted is generated in the process of providing the target service, the transmission performance of the data packet to be transmitted, namely the service quality of the target service, can be ensured by scheduling according to the method.
