Description

Communication method and apparatus

[0001] The present application claims priority to the Chinese Patent Application No. 202410662073.0, filed on May 24, 2024, and entitled "Communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of wireless communication, and in particular to a communication method and apparatus. BACKGROUND

[0003] Different scenarios or data types have different requirements for network capabilities. The latency requirements of different services may be different, and the reliability requirements of different services may also be different. The service volume size is related to the environment in which the user equipment (UE) is currently located, or the content that the UE needs to be issued by the network side. Taking a vehicle-to-everything (V2X) scenario as an example, different scenarios or events require different confidence levels, and the processing performance of the vehicle side is also different. When the network signal is unstable or the vehicle is at the edge of a cell, the network cannot provide the best service capability for all vehicles. For example, the vehicle side expects the network to provide 4 MB (megabytes) of data in 20 ms (milliseconds), but the network side can only provide 2 MB of data in 20 ms. The mismatch between the expectations of the vehicle side and the actual capabilities of the network side can cause the continuity of services to be unable to be guaranteed. Therefore, how to guarantee the continuity of services obtained by the vehicle side through the network side is a problem to be solved. SUMMARY

[0004] Embodiments of the present application provide a communication method and apparatus, which can guarantee the continuity of service data transmission and the continuity of service experience in the case of poor channel quality of the network.

According to the first capability or the first requirement, first data associated with the first service is sent to the second apparatus.

[0006] From the technical effect, after the third device receives the first capability or the first demand indicated by the first information of the second device in the embodiment, the first data of the first service is sent according to the first capability or the first demand, which can ensure that the second device receives the first data and can process the first data, and avoid the interruption of the first service due to the poor current signal quality, which leads to the second device unable to receive the first data.

[0052] Taking a terminal as a vehicle-mounted communication module as an example, the technical solutions provided by the present application can be specifically applied to scenarios including vehicle-to-vehicle (V2V) communication (or also referred to as device-to-device (D2D) communication), vehicle-to-infrastructure / vehicle / pedestrian (V2X) communication, machine-to-machine (M2M) communication, machine type communication (MTC), and internet of things (IoT) communication system or other communication system, etc. Referring to FIG. 1B, which is a V2X communication schematic diagram provided by the embodiments of the present application, as shown in (a) of FIG. 1B, it is V2V communication, (b) of FIG. 1B is vehicle-to-pedestrian (V2P) communication, (c) of FIG. 1B is vehicle-to-infrastructure (V2I) communication, and (d) of FIG. 1B is vehicle-to-network (V2N) communication.

[0053] The present application is applicable to the communication scenarios with network coverage and without network coverage when applied in a system of V2X communication, and the mode of user autonomous selection of resources. Referring to FIG. 1C, FIG. 1C is a schematic diagram of a communication scenario provided by an embodiment of the present application, as shown in FIG. 1C, (a) in FIG. 1C represents that the communication terminal is located in the network (or the signal of the network device) coverage range, (b) in FIG. 1C represents that part of the communication terminals are located in the network coverage range and part of the communication terminals are located out of the network coverage range, and (c) in FIG. 1C represents that the communication terminal is located out of the network coverage range.

[0054] The prior art of the embodiments of the present application is introduced as follows.

[0055] With the development of wireless network technology, a new generation of network technology can provide more and more high-quality network services. For example, 5G network technology is a new generation of broadband mobile communication technology with high speed, low latency and large connection characteristics. For the above-described V2X communication, taking vehicle communication as an example, the prior art has developed to cellular Vehicle To Everything (C-V2X). It is a V2X communication technology developed based on a cellular system. It utilizes and enhances the current cellular network functions and elements to realize low-latency and high-reliability communication between various nodes in the vehicle network, including the above-described V2V, V2P, V2I, and V2N, etc. With the evolution of the cellular system from LTE to 5G, C-V2X evolves from LTE-V2X to NR-V2X (New Radio V2X, NR-V2X). 5G NR V2X can support lower transmission latency, more reliable communication transmission, higher throughput, and better user experience, meeting the needs of more extensive application scenarios.

[0056] Ideally, the network can provide services that meet the requirements of high speed, low latency, and high reliability. However, in reality, the network capability cannot always meet the best, most complete or most perfect service transmission requirements. In fact, the latency requirements of different services may not be the same, and the reliability requirements of different services may also not be the same. The amount of traffic and the environment in which the UE is currently located, or the content that the UE needs to be issued by the network side, are also related. Therefore, different scenarios or data types have different requirements for network capabilities. Taking the vehicle-to-scenario as an example, some examples of service requirements corresponding to vehicle-to-services are provided as follows.

[0057] (1) Obstructed View Assist based on video stream

[0058] Obstacle view assistance based on video stream is that when a vehicle encounters an obstacle that blocks its view on the road, at an intersection, or on a sidewalk, it queries nearby entities that can provide a video stream that extends the vehicle's view and allows it to see around / behind the obstacle.

[0059] Other vehicles, or roadside devices installed on the road, are equipped with one or more closed-circuit television cameras with communication functions, which can respond to the vehicle's request to send real-time video streams to the vehicle through the camera.

[0060] Table 1

[0061] Table 1 shows examples of service requirements corresponding to the obstacle view assistance service based on video streams, including rate requirements, latency requirements, and reliability requirements during the transmission of service data.

[0062] (2) High-definition map collecting and sharing

[0063] High-definition map collecting and sharing is that when an autonomous vehicle enters a road covered by infrastructure, the sensors it registers receive information from the infrastructure, including environmental data provided by dynamic and static objects on the road. These data are used to improve the reliability of the vehicle's own sensor observations and extend its field of view.

[0064] Table 2

[0065] Table 2 shows the service requirements corresponding to the high-definition map collecting and sharing service, which also includes rate requirements, latency requirements, and reliability requirements during the transmission of service data.

[0066] (3) Accident report

[0067] Accident report is that when the host vehicle is involved in an accident, the accident report contains time window recorded vehicle system data, rich perception information, environmental conditions, and any available camera views.

[0068] Table 3

[0069] Table 3 shows the service requirements corresponding to the accident report service, which also includes rate requirements, latency requirements, and reliability requirements during the transmission of service data.

[0070] According to the above introduction, different services in the vehicle field have different timeliness requirements, reliability requirements, rate requirements, etc. Correspondingly, these service scenarios or data types also have different requirements for network capabilities. When the network signal is unstable or the vehicle is at the edge of the cell, the network cannot provide the best service capability for all vehicles. For example, the vehicle side expects the network to provide 4MB of data in 20ms, while the network side can only provide 2MB of data in 20ms. Referring to FIG. 1D, FIG. 1D is a schematic diagram of the relationship between network capability and service demand provided by an embodiment of the present application, as shown in FIG. 1D, at t0-t1, the network capability and the service demand are not matched, and the network capability cannot meet the service demand. When a high-layer service packet needs to be split into multiple small packets, and when the transmitted data packet exceeds the timeliness requirement (packet delay budget, PDB), the higher layer, such as the APP layer, cannot obtain all valid information, so it cannot correctly / fully process this packet, and therefore the previously transmitted correct data packet will also be discarded, which will further cause the continuity of the service to be unable to be guaranteed. At the same time, it is also a waste of resources.

[0071] Therefore, how to ensure that the vehicle side obtains continuous services through the network side is a problem to be solved.

[0072] Based on this, an embodiment of the present application provides a communication method. Referring to FIG. 2A, FIG. 2A is a flowchart of a communication method provided by an embodiment of the present application, the method includes the following steps:

[0073] 201. The second device sends first information to the third device, the first information indicating a first capability or a first demand, the first capability indicating a channel quality between the first device and the second device, and the first demand indicating a quality of service requirement of the first device for the first service, and the first capability meeting a first service carrying the first demand.

[0074] The second device in the embodiment of the present application refers to a RAN device, and the specific RAN device can be as described in the foregoing FIG. 1A. The third device refers to a device providing service data, and can be a network element in a core network or a server in the Internet. In a D2D communication scenario, the third device can also refer to a UE. In the embodiment, the third device is described by taking a server as an example. The first device refers to a device receiving service data, that is, a UE. In subsequent examples, the UE is mainly described by taking a vehicle-mounted device as an example. However, it can be understood that when the UE is another specific device, the method of the embodiment of the present application can also be used.

[0075] The first device and the third device are used for interaction of service data, and the second device is used for forwarding of service data.

[0076] The first information sent by the second device to the third device can be carried in downlink control information (DCI), uplink control information (UCI), a medium access control layer control element (MAC CE), RRC, etc.

[0077] The first information can indicate a first capability, which indicates a channel quality between the first device and the second device, i.e., a channel quality between the UE and the RAN device. The channel quality can be represented by one or more of a reference signal receiving power (RSRP), a reference signal receiving quality (RSRQ), a signal to interference plus noise ratio (SINR), a signal-to-noise ratio (SNR), or other parameters that can represent the channel quality. These channel quality parameters can be obtained by measuring a reference signal, such as a demodulation reference signal (DMRS), a channel state information reference signal (CSI-RS), a synchronization signal and physical broadcast channel (PBCH) block (SSB), etc.

[0078] The manner in which the second device obtains the first capability can include the following:

[0079] (1) The second device detects or trains to obtain the first capability.

[0080] ① The second device detects to obtain the first capability. The second device (i.e., the RAN device) detects to obtain one or more parameters for representing the channel quality, such as the current RSRP, RSRQ, SINR, or SNR, and takes these detected parameters as the first capability.

[0081] ② The second device trains by AI to obtain the first capability.

[0082] Because the first capability is a kind of prediction information. The second device can obtain the first capability by the current parameters and the change characteristics, combined with AI training.

[0083] Specifically, the first capability can be obtained by the following change characteristics training:

[0084] The first kind: change characteristics in time dimension. For the moving UE (the first device), especially the vehicle, in a short time, the moving distance is limited, and the vehicle speed is also relatively constant, and the channel also has certain channel correlation in time. Therefore, the predicted channel quality at the next moment can be obtained by AI training based on the known channel quality of the UE at the previous moment and the change characteristics in time dimension, such as the predictable change of the moving distance of the UE and the RAN device, the change of the vehicle speed, etc. In addition, if there are sudden characteristics affecting the channel quality parameters during the vehicle driving, such as passing through a bridge, a tunnel, etc., the sudden characteristics can also be input as input parameters into the AI training model for training to obtain the channel quality at the next moment. In addition, the mobility of the vehicle can cause the channel to have a Doppler frequency offset, and then if the moving speed of the vehicle can be known, the Doppler frequency offset of the channel can be compensated, so as to obtain more accurate channel quality.

[0085] Referring to FIG. 2B, FIG. 2B is a schematic diagram of obtaining channel quality based on change characteristics training provided by an embodiment of the present application, as shown in (a) of FIG. 2B, UE#1 moves from position 1 at t0 moment to position 2 at t1 moment, and the channel quality between the two has correlation. In the case of obtaining the channel quality at t0 moment, AI training can be performed based on the known channel quality and such correlation (or also difference, i.e. the aforementioned sudden characteristics) to obtain the predicted channel quality at t1 moment as the first capability.

[0086] The second kind: change characteristics in space dimension. In principle, for the moving UE, especially the vehicle, the driving path of the vehicle in space is predictable, and the channels of different vehicles driving to the same position are correlated, so for different vehicles in the same lane, the channel of the front vehicle can be used as a reference for the channel quality information of the rear vehicle. Therefore, the predicted channel quality of the rear vehicle can be obtained by AI training based on the channel quality of the front vehicle in the lane and the change characteristics in space dimension, such as the change of the RAN device channel quality, the change of the vehicle speed, etc. caused by the change of time. In addition, if there are sudden characteristics affecting the channel quality parameters during the vehicle driving, such as sudden severe weather, etc., the sudden characteristics can also be input as input parameters into the AI training model for training to obtain the channel quality of the rear vehicle.

[0087] Referring to (b) in FIG. 2B, UE#1 and UE#2 arrive at position 2 at time t and time t+1 respectively, and the channel quality between the two UEs for the position is also correlated. In the case of obtaining the channel quality of UE#1 at position 2, the AI training can be performed based on the known channel quality and the correlation (and also possibly the difference) to obtain the predicted channel quality of UE#2 at the position at time t+1 as the first capability.

[0088] (2) The second device obtains the first capability sent by the first device.

[0089] The second device actively obtains the first capability from the first device, or the second device passively receives the first capability sent by the first device. That is, the first capability is obtained by UE detection or artificial intelligence (AI) training, and then sent to the RAN device by the UE. The way in which the UE obtains the first capability by AI training is the same as the process in which the RAN device obtains the first capability by AI training, and will not be described here.

[0090] The second device can obtain the channel quality at the previous time from the first device, and then obtain the channel quality at the next time by AI training, and finally determine the first capability. The way in which the second device obtains the first capability can be any of the above ways (1) and (2), or a combination of the two ways.

[0091] In summary, referring to FIG. 2C, which is a flow chart of a communication method provided by an embodiment of the present application, in the case where the first information sent by the second device indicates the first capability, the method of FIG. 2A can further include the following steps:

[0092] 2011, the second device detects or trains to obtain the first capability.

[0093] Alternatively, the method of FIG. 2A can further include:

[0094] 2012, the first device detects or trains to obtain the first capability;

[0095] 2013, the first device sends the first capability to the second device. Correspondingly, the second device receives the first capability.

[0096] Among them, steps 2011 and steps 2012-2013 are optional steps, that is, only one of them can be executed, or they can be executed in combination. Step 2011 is referred to as operation a, and steps 2012-2013 are referred to as operation b.

[0097] Optionally, the first device also reports lane information, path information, etc. to the second device, for training or input of an AI model of the second device, to obtain the first capability as an output of the AI model.

[0098] Optionally, the second device further determines the first capability according to network load, network jitter delay, etc.; or uses these parameters for training or input of an AI model, to obtain the first capability as an output of the AI model.

[0099] The first information can also indicate the first requirement, which indicates the quality of service requirement of the first device for the first service, i.e., the quality of service requirement of the UE for the first service. The quality of service requirement quantifies the service requirement parameter of the UE for the server to send data of the first service, which can include one or more of service confidence, service type, transmission delay, transmission reliability, transmission rate, and service data volume.

[0100] For example, the first service is a high-precision map collection and sharing service, and the service requirement information of the service can refer to Table 2, or for example, the first service is an obstacle view assistance service, and the service requirement information of the service can refer to Table 1.

[0101] The first requirement in the embodiment of the application refers to the quality of service required by the UE based on the predicted channel quality. Or in other words, the first requirement refers to the quality of service requirement that can be met by the first capability. Therefore, for each service, there can be a corresponding relationship between multiple sets of channel quality and quality of service requirement, including the corresponding relationship between the first requirement and the first capability. For details, refer to the following table:

[0102] Table 4

[0103] As shown in Table 4, for the first service, there can be N sets of quality of service requirements, each of which can include corresponding (information) transmission rate, transmission reliability, or transmission delay, etc. Different sets of quality of service requirements can be completely different or partially the same. Each set of quality of service requirements corresponds to a channel quality. The better the channel quality, the higher the corresponding quality of service requirement, and vice versa.

[0104] For details of the specific channel quality and quality of service requirement, refer to the following Table 5:

[0105] Table 5

[0106] As shown in Table 5, the channel quality is represented by an RSRP value, the larger the value, the better the signal quality. For example, when the RSRP is -80 dBm (decibel-milliwatt), it means the channel quality is very good, which can correspond to a high quality of service requirement, i.e. the transmission rate is 100 Mbps (megabits per second), the transmission reliability is 99.99%, and the transmission delay is 20 ms (millisecond). When the channel quality becomes worse, the quality of service requirement is correspondingly reduced, which can be to reduce one of the parameters, for example, when the RSRP is reduced from -80 dBm to -90 dBm, the transmission rate requirement is reduced from 100 Mbps to 50 Mbps. Or several parameters can be reduced at the same time, for example, when the RSRP is reduced from -100 dBm to -110 dBm, the transmission reliability requirement is reduced from 99.99% to 99.9%, and the transmission delay requirement is reduced from 20 ms to 50 ms.

[0107] Or the channel quality and the quality of service requirement can be set according to the following Table 6:

[0108] Table 6

[0109] As shown in Table 6, the RSRP used to represent the channel quality can be a range value. For example, the channel quality 1 in Table 6 corresponds to RSRP > -85 dBm (decibel-milliwatt), which means the channel quality is very good, and it can support the highest quality of service requirement.

[0110] Or the channel quality parameter and the quality of service requirement can be set according to the following Table 7:

[0111] Table 7

[0112] As shown in Table 7, the channel quality parameter can also be represented by SINR. For example, the channel quality 1 in Table 7 corresponds to SINR > 25, which means the channel quality is very good, and it can support the highest quality of service requirement.

[0113] Or the channel quality parameter and the quality of service requirement can be set according to the following Table 8:

[0114] Table 8

[0115] As shown in Table 8, the channel quality parameter can be represented by multiple parameters. For example, the channel quality 4 in Table 8 corresponds to RSRP < -105 dBm and SINR ≤ 10, which means the channel quality is poor, and it can support a greatly reduced quality of service requirement compared to the ideal channel quality, i.e. the transmission rate is reduced to 10 Mbps, the transmission reliability requirement is reduced to 99.9%, and the transmission delay requirement is reduced to 50 ms.

[0116] Optionally, the correspondence between the channel quality and the quality of service requirement can include the correspondence between the quality of service requirement in an ideal network state. For example, the channel quality 1 of a certain service corresponds to the quality of service 1, which is the quality of service requirement of the service in normal circumstances. Then, when the first capability of the second device indicates the channel quality 1 (or indicates the quality of service 1) to the third device, the third device can send the service data of the service according to the normal quality of service requirement, without the need to reduce the quality of service requirement of the service data.

[0117] Alternatively, the normal quality of service requirement of the service is not included in the correspondence, but is determined by a threshold. When the server side determines that the first capability or the first requirement sent by the RAN device is higher than (or equal to) the threshold, the service data is provided according to the normal quality of service requirement, otherwise the server sends the service data according to the first requirement (corresponding to the first capability).

[0118] In some cases, the standard of the service for data transmission cannot be reduced. That is, the quality of service requirement of the service must have a lower delay, a higher reliability and a faster transmission rate. Therefore, the quality of service requirement can further include the data size. The quality of service requirement can be reduced by reducing the data size. For example, taking the high-precision map collection and sharing service as an example, the transmission range of the map can be reduced from 500 m (meters) to 100 m, or only the data of the lane related to the vehicle is transmitted, or the original 300 objects are transmitted, and the number of objects is reduced to 200.

[0119] Referring to FIG. 2D, FIG. 2D is a schematic diagram of the first information indicating the first requirement according to an embodiment of the present application. As shown in FIG. 2D, the UE or the RAN device predicts in advance that the UE is in the NLOS area at time t11-t12 at time t01, and the RAN device indicates through the first information that the first capability corresponding to the NLOS area can only meet the quality of service requirement of the service type of quality of service 3.

[0120] For the second device, the first requirement needs to be determined before the first information indicating the first requirement is obtained. The determination of the first requirement can include the following methods:

[0121] (1) The second device obtains the first capability, and determines the first requirement according to the first capability. The first capability and the first requirement have a correspondence.

[0122] As described above, the first requirement refers to a quality of service requirement determined based on a predicted channel quality between the UE and the RAN device. Assuming that the predicted channel quality is a first capability, the first requirement corresponding to the first capability can be determined according to the first capability. As shown in Table 4, in a case where the first capability is determined to be channel quality 2, the first requirement corresponding to the first capability can be determined to be service quality 2.

[0123] As described above, the second device obtains the first capability in a manner including receiving the first capability from the first device or detecting or training to obtain the first capability. Details are not repeated here.

[0124] After the second device obtains the first capability, the first capability and the first requirement corresponding thereto (for example, the correspondence is represented by a table in Table 4, or can also be represented by other manners such as text) can be stored in the second device, and then the second device can query the first requirement corresponding to the first capability according to the stored correspondence.

[0125] (2) The second device receives the first requirement sent by the first device.

[0126] Since the first device (UE) can also detect (or AI train) to obtain the first capability, assuming that the first capability and the first requirement corresponding thereto are stored in the UE, the UE can also query the first requirement corresponding to the first capability according to the correspondence.

[0127] Then, the UE sends the first requirement to the RAN device according to a request of the RAN device (the second device) or actively.

[0128] In combination with the above description, refer to FIG. 2E, which is a flowchart of a communication method provided by an embodiment of the present application. As shown in FIG. 2E, in a case where the first information sent by the second device indicates the first requirement, the method in FIG. 2A can further include the following steps:

[0129] 2014. The second device obtains the first capability and obtains the first requirement according to the correspondence between the first capability and the first requirement.

[0130] Or the method in FIG. 2A can further include:

[0131] 2015. The first device detects or trains to obtain the first capability and obtains the first requirement according to the correspondence between the first capability and the first requirement.

[0132] 2016. The first device sends the first requirement to the second device. Correspondingly, the second device receives the first capability.

[0133] The step 2014 and the steps 2015-2016 are optional steps, i.e., only one of them can be executed. The step 2014 is referred to as operation c, and the steps 2015-2016 are referred to as operation d.

[0134] In some cases, the first capability and / or the first requirement further include a corresponding first identifier. For details, refer to Table 9 below:

[0135] Table 9

[0136] As shown in Table 7, for each set of channel quality and service quality requirement, there is a corresponding identifier (or number, label, etc.). The first capability and the first requirement correspond to the first identifier. When the first capability or the first requirement is indicated by the first information, it can also be indicated by sending the first identifier. That is, the first identifier is included in the first information.

[0137] In addition, since the first requirement is a parameter related to time, and generally, the first requirement is a parameter lower than the regular service quality requirement of the service. If the UE always acquires service data according to the lower service quality requirement, it can be detrimental to the execution of the service. Therefore, when the second device indicates the first capability or the first requirement by the first information, it can also indicate the time period corresponding to the first capability or the first requirement, indicating that the UE only acquires service data according to the first capability or the first requirement within the time period, and acquires service data according to the regular service requirement outside the time period.

[0138] Alternatively, the second device sends a second information to the third device after a period of time after sending the first information, and the second information indicates that the first capability or the first requirement corresponding to the first information is invalid.

[0139] The above two methods can reduce the impact on the service performance while enabling the UE to send the first capability to obtain continuous service data, thereby improving the user experience.

[0140] 202. The third device sends first data to the second device according to the first capability or the first requirement, and the first data is associated with the first service. Correspondingly, the second device receives the first data.

[0141] After the third device (server) receives the first information, the first capability or the first requirement is obtained. Then, the server can perform the following operations:

[0142] 1. The server sends first data according to the first capability or the first requirement.

[0143] (1) The server sends first data according to the first capability.

[0144] The server sends the first data according to the first capability, which can include the following two cases:

[0145] ① The server sends the first data completely according to the first capability. Since the transmission of the first data is performed according to the service quality requirement corresponding to the first capability, after obtaining the first capability, the server can first determine the third requirement corresponding to the first capability, and then send the first data according to the service quality requirement in the third requirement. That is, the server stores the correspondence between the first capability and the third requirement.

[0146] The foregoing description illustrates that the UE or the RAN device stores the correspondence between the first capability and the first requirement, but for the server, the service quality requirement determined by the first capability is not necessarily the same first requirement as stored in the UE or the RAN device. Therefore, the server needs to determine the third requirement corresponding to the first capability according to the correspondence between the channel quality and the service quality requirement stored by itself.

[0147] For example, in the RAN device, when the first capability is SINR ∈ [11, 15], the corresponding first requirement is 10 Mbps @ 99.99% @ 20 ms, and the server can only provide the combination of the service quality requirement of 10 Mbps @ 99.9% @ 20 ms. At this time, the first requirement and the third requirement are not completely the same.

[0148] For another example, assume that the service quality requirement 1 corresponding to the channel quality 1 stored in the RAN device is [0.9 MB, 1 MB] data, and the service quality requirement 2 corresponding to the channel quality 2 is [0.8 MB, 0.9 MB] data. After the server receives the service quality 1, it decides to send 0.95 MB data, which satisfies the service quality requirement 1, but it cannot be said that it is completely the same as the service quality requirement 1. That is, the first requirement and the third requirement are not completely the same.

[0149] In general, the above-mentioned cases that the third requirement is completely the same as the first requirement, the third requirement is partially the same as the first requirement, or the third requirement is within the range of the first requirement can be referred to as the server completely sending the first data according to the indication information of the RAN device.

[0150] ② The server sends the first data to the second device according to the second capability, which is lower than the first capability.

[0151] That is to say, after receiving the first information of the RAN device, the server does not send the first data according to the first capability indicated by the first information completely. Instead, the server sends the first data according to a second capability lower than the first capability. The first data is sent according to the second capability, and in essence, the first data is sent according to a fourth requirement corresponding to the second capability. The fourth requirement that the server can meet is lower than the third requirement requested by the RAN device, and possible reasons include that the server needs to meet the quality of service requirements of other services at the same time, or the quality of service of the service cannot be reduced according to the requested requirement.

[0152] For example, in the RAN device, the first requirement corresponding to the first capability is (0.5MB, 1MB] data, and the second requirement corresponding to the second capability is (0.3MB, 0.5MB] data. The third requirement determined by the server side according to the first capability is 1MB data, but the server can only send the first data of the first service according to the fourth requirement, that is, 0.5MB data. That is to say, the server side actually sends the first data of the first service according to the second capability of the RAN device.

[0153] (2) The server sends the first data according to the first requirement.

[0154] The server sending the first data according to the first requirement can include the following two cases:

[0155] ① The server sends the first data according to the first requirement completely.

[0156] That is to say, after receiving the first requirement, the server sends the first data according to the quality of service requirement parameter in the first requirement. Similarly, it also includes the case that the server sends the first data according to the third requirement, and the third requirement is completely the same as the first requirement, the third requirement is partially the same as the first requirement, or the third requirement is within the range of the first requirement.

[0157] ② The server sends the first data to the second device according to the second requirement, and the second requirement is lower than the first requirement.

[0158] That is to say, after receiving the first information of the RAN device, the server does not send the first data according to the first requirement indicated by the first information completely. Instead, the server sends the data according to a second requirement lower than the first requirement. Possible reasons include that the server needs to meet the quality of service requirements of other services at the same time, or the quality of service of the service cannot be reduced according to the requested requirement.

[0159] For example, in the RAN device, the first requirement is a transmission rate (200Mbps, 300Mbps], and the second requirement is (100Mbps, 200Mbps]. After obtaining the first requirement, the server side sends data at 190Mbps. That is to say, the server side actually sends the first data of the first service according to the second requirement of the RAN device.

[0160] Optionally, the first information sent by the second device includes the first identifier, i.e. the second device indicates the first requirement or the first capability through the first identifier. In this case, the server can store the correspondence as shown in Table 9. Alternatively, the server at least stores the correspondence between the first identifier and the first requirement, which can be referred to Table 10:

[0161] Table 10

[0162] As shown in Table 8, the server stores the correspondence between the first identifier and the quality of service requirement, which includes the correspondence between the first requirement and the first identifier. After receiving the first identifier, the server can determine the first requirement according to the correspondence, and send the first data according to the first requirement.

[0163] It can be seen that, in the embodiments, after the third device receives the first capability or the first requirement indicated by the first information of the second device, the third device sends the first data of the first service according to the first capability or the first requirement, which can ensure that the second device receives the first data and can process the first data, and avoids the interruption of the first service due to the poor current signal quality, which leads to the fact that the second device cannot receive the first data. That is, the process ensures the continuity of the service or the business.

[0164] 2. The server does not send the first data according to the first capability or the first requirement, but sends the first data according to the original service requirement. In addition, the server also sends feedback information for indicating that the first information has been received.

[0165] In some cases, although the server receives the first information and determines the first capability or the first requirement, the server does not send the first data according to the first capability or the first requirement. Possible reasons include that the service data cannot be compressed, the quality of service requirement cannot be lowered, etc. The server also sends the first data according to the original service requirement, but at the same time, the server sends a feedback information to the RAN device, indicating that the first information has been received. Further, the feedback information can also indicate that the second device sends an updated first capability or first requirement, so that the server can send the first data according to the updated first capability or first requirement.

[0166] After the RAN device receives the first data sent by the server, the RAN device further forwards the first data to the UE. That is, after step 202, step 203 (not shown in the figure) can also be included, i.e. the second device forwards the first data to the first device. Correspondingly, the first device receives the first data. That is, the transmission of the first data from the server to the RAN device and then to the UE is completed.

[0167] It can be seen that, in the embodiment of the present application, after the third device receives the first information of the second device indicating the first capability or the first demand, the first data of the first service is not sent according to the first capability or the first demand, but the feedback information is sent to indicate that the first information has been received, so that the second device can make further response to cope with the problem of possible interruption of sending service data. The intelligence in the service or service process is improved, and the user experience is improved.

[0168] The above embodiment describes the case that the third device sends the first data according to the first information sent by the second device, which corresponds to the scenario of downlink data transmission. The scenario of uplink data transmission is introduced below. Referring to FIG. 3A, FIG. 3A is a flowchart of another communication method provided by an embodiment of the present application, as shown in FIG. 3A, the method comprises the following steps:

[0169] 301, the first device obtains a first demand, the first demand has a corresponding relationship with a first capability, the first capability indicates a channel quality between the first device and the second device, and the first demand indicates a quality of service demand of the first device for a first service.

[0170] The first device, the second device and the third device involved in the embodiment of the present application have the same meaning as described in the foregoing FIG. 2A-FIG. 2D, which will not be described here. Similarly, in the example of the present embodiment, the first device specifically corresponds to the UE, the second device corresponds to the RAN device, and the third device corresponds to the server.

[0171] The first device obtaining the first demand specifically comprises two steps: first, the first device obtains the first capability; second, the first device determines the first demand according to the corresponding relationship between the first capability and the first demand.

[0172] The first device obtains the first capability in the following two ways:

[0173] (1) The first device obtains the first capability by self-detection or training.

[0174] (2) The first device receives indication information of the first capability from the second device, and obtains the first capability according to the indication information of the first capability.

[0175] The UE obtains the first capability in the above two ways, which is similar to the description of the RAN device obtaining the first capability in the foregoing embodiment, which will not be described here. Similarly, the UE can obtain the first capability in one of the two ways, or can obtain the first capability by combining the two ways, for example, the UE first receives the channel quality detected by the network side from the RAN device, and then obtains the first capability by self-training. The specific description is the same as the related description of the foregoing embodiment, which will not be described here.

[0176] Based on the above description, referring to FIG. 3B, which is a flowchart of a communication method provided by an embodiment of the present application, the method of FIG. 3A can further include the following steps, as shown in FIG. 3B:

[0177] 3011a. The first device detects or trains to obtain the first capability by itself.

[0178] Alternatively,

[0179] 3011b. The first device receives indication information of the first capability from the second device, and obtains the first capability according to the indication information of the first capability.

[0180] 3012. The first device determines the first requirement according to the correspondence between the first capability and the first requirement.

[0181] That is, the first device can select any one of steps 3011a and 3011b to perform, and then perform step 3012. Steps 3011a and 3012, or steps 3011b and 3012, can replace step 301 in the foregoing FIG. 3A.

[0182] 302. The first device sends second data to the second device according to the first requirement, and the second data is associated with the first service. Correspondingly, the second device receives the second data.

[0183] The UE sends the second data to the second device according to the first requirement, including the following two cases:

[0184] (1) The UE sends the second data according to the first requirement.

[0185] The second data is data associated with the first service. That is, for the first service, whether the data sending node UE in uplink transmission or the data sending node server in downlink transmission sends data according to the first requirement. So that the first capability corresponding to the current network can meet the data transmission requirement of the first service.

[0186] (2) The UE sends the second data according to the fourth requirement. The fourth requirement is lower than the first requirement.

[0187] In some cases, for example, when the data cannot be compressed or weakened as required by the first requirement, the UE can send the second data according to the fourth requirement which is lower than the first requirement. In this way, the UE can also successfully send the second data.

[0188] In addition, after the second device receives the second data, it can be forwarded to the server, that is, the method can further include the following steps (not shown in the figure):

[0189] 303、The second device forwards the second data to the third device. Correspondingly, the third device receives the second data.

[0190] It can be seen that, in the embodiments of the present application, after the first device determines the first requirement corresponding to the first capability of the current network, the second data of the first service is sent according to the first requirement, which can ensure that the first device successfully sends out the second data, and avoid the interruption of the first service due to the fact that the first capability cannot meet the first requirement. That is, the process guarantees service continuity.

[0191] After receiving the first capability or the first requirement indicated by the first information of the second device, the first data of the first service is not sent according to the first capability or the first requirement, but feedback information is sent to indicate that the first information is received, so that the second device can make further response to cope with the problem of possible interruption of service data sending. The intelligence in the service execution process is improved, and the user experience is improved.

[0192] It can be ensured that the second device receives the first data and can process the first data, avoiding the fact that the second device cannot receive the first data due to poor current signal quality, and further avoiding the interruption of the first service. That is, the process guarantees service continuity.

[0193] Please refer to FIG. 4, which is a structural schematic diagram of a communication device provided by an embodiment of the present application. The communication device can be used to execute any one of the methods in the foregoing embodiments.
