Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to a scheduling control method and a wireless intelligent controller. Background Art

[0002] Figure 1 The shown Open Radio Access Network (O-RAN) represents the future development direction of wireless networks: open and intelligent. Through open wireless data collection, intelligent management and control of wireless networks are carried out. Among them, data collection includes real-time service-side data and network-side data collection, and the regulation of wireless networks is mainly to adjust the network according to the service state, so as to achieve the purpose of ensuring the Quality of Service (QoS) of services. Among them, the network quality indicators that need to be mainly guaranteed are bandwidth and latency.

[0003] Figure 1 The main function of the Non Real Time RAN Intelligent Controller (Non-RT RIC) is to identify services, perform artificial intelligence (AI) model training or mathematical modeling on network-side and service-side data, obtain models corresponding to different service states, input the real-time collected data into these models, and obtain corresponding service state information. The Near Real Time RAN Intelligent Controller (Near-RT RIC) has an algorithm for assisting base station radio resource management (RRM). The algorithm performs scheduling control according to the service state information. The interface between the two network elements is the A1 interface, as Figure 2 shown, the expected value of network quality indicators and feedback information are transmitted in the interface, and this information is triggered when it is detected that a service needs to be guaranteed.

[0099] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0100] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a scheduling control method provided in the first embodiment of the present invention. This method is applied to a non-real-time wireless intelligent controller and includes the following steps:

[0101] Step 31: Send a first piece of information to the near-real-time wireless intelligent controller. The first piece of information includes an expected value of a network quality index and sensitive indication information. Among them, the sensitive indication information is used to indicate the network quality index sensitive to the service, and the network quality index includes at least one of bandwidth and delay.

[0102] Among them, the scheduling method provided in the embodiments of the present invention is a scheduling method for the target service. Therefore, the first piece of information is the first piece of information for the target service, and this will not be elaborated one by one in the following related parts.

[0103] The sensitive indication information can also be used to indicate the sensitivity degree of the service to the network quality index, and different services have different sensitivity degrees to the network quality index.

[0104] The specific content of the expected value of the network quality indicator included in the first information is related to the network quality indicators sensitive to the service. For example, if the target service is sensitive to latency, then the expected value of the network quality indicator includes at least the expected latency. If the target service is sensitive to bandwidth, then the expected value of the network quality indicator includes at least the expected bandwidth. If the target service is sensitive to both bandwidth and latency, then the expected value of the network quality indicator includes at least the expected bandwidth and the expected latency.

[0105] The network quality indicators sensitive to different services are different. The target service may be only sensitive to bandwidth, may be only sensitive to latency, or may be sensitive to both bandwidth and latency.

[0106] In the scheduling control method provided by the embodiments of the present invention, the non-real-time radio intelligent controller clearly indicates the network quality indicators sensitive to the service. Therefore, for the network quality indicators that are not sensitive to the service, it is not necessary to ensure them through scheduling adjustment, thereby avoiding unnecessary scheduling adjustment for this service. While ensuring the Quality of Service (QoS), it reduces the waste of network resources. Moreover, the embodiments of the present invention can treat different services differently. Different services have different requirements for network quality indicators (such as bandwidth, latency), and there are corresponding different adjustment schemes during adjustment, which can further avoid unnecessary adjustments.

[0107] In addition, based on the A1 interface, the experience or model of the non-real-time radio intelligent controller can be combined with the service status of the real-time radio intelligent controller with relatively small changes to the existing base stations, and then real-time adjustments can be made to ensure the services of users. The time granularity is small, the adjustment range is small, the adjustment period is short, the impact on other users is small, and the impact on the entire network is small.

[0108] The above scheduling control method will be illustrated by examples below.

[0109] Optionally, the sending of the first information to the near-real-time radio intelligent controller further includes:

[0110] Receiving the first feedback information sent by the near-real-time radio intelligent controller. The first feedback information includes the first adjustment result of the near-real-time radio intelligent controller for scheduling adjustment according to the first information. The first adjustment result can be used to indicate whether the network quality indicator has been adjusted. The first feedback information may further include the current available bandwidth of the base station. The first feedback information may further include sensitive indication information, such as bandwidth sensitive indication information and latency sensitive indication information.

[0111] Optionally, the first feedback information further includes a current network quality metric value, which is used to determine network fluctuation information, and the network fluctuation information is used to indicate the degree of change of the network quality metric. Network fluctuation information can also be referred to as network fluctuation parameters.

[0112] For example, a non-real-time wireless intelligent controller can calculate the variance of the bandwidth over a period of time as the network fluctuation information, and can also calculate the variance of the delay over a period of time as the network fluctuation information.

[0113] In addition, the non-real-time wireless intelligent controller will also adjust the network quality metric expectation value according to the current network quality metric value, for example, adjust the bandwidth expectation value according to the current bandwidth value, and adjust the delay expectation value according to the current delay.

[0114] Optionally, the method further includes:

[0115] Receiving the network quality metric values sent by the near-real-time wireless intelligent controller multiple times;

[0116] Determining network fluctuation information according to the received network quality metric values, where the network fluctuation information is used to indicate the degree of change of the network quality metric.

[0117] Specifically, the non-real-time wireless intelligent controller can calculate the network fluctuation information by using a model obtained through AI model training or mathematical modeling.

[0118] Optionally, the first information may further include network fluctuation information.

[0119] Optionally, the method further includes:

[0120] Sending second information to the near-real-time wireless intelligent controller, where the second information includes service adjustment instruction information and network fluctuation information, the service adjustment instruction information is used to indicate adjusting the network quality metric, and the network fluctuation information is used to indicate the degree of change of the network quality metric; wherein, the second information may further include sensitive indication information, and the sensitive indication information in the second information is the same as or different from the sensitive indication information in the first information.

[0121] The first information and the second information can be Figure 2 the status information in.

[0122] Among them, the service adjustment instruction information may include whether the current network quality indicators meet the service requirements. For example, if the current bandwidth does not meet the service requirements, then it instructs the near-real-time wireless intelligent controller to adjust the bandwidth. If the current latency does not meet the requirements, then it instructs the near-real-time wireless intelligent controller to adjust the latency. If both the current latency and bandwidth do not meet the requirements, then it instructs the near-real-time wireless intelligent controller to adjust both the latency and bandwidth simultaneously.

[0123] After the previous adjustment, although the network quality indicators of the service meet the corresponding expected values, with the change of the network, the service may still experience lag and large delays. Therefore, during the service duration, it is necessary to schedule and adjust in real time according to the network fluctuations to further ensure that the service quality meets the service requirements.

[0124] In the embodiments of the present invention, based on bandwidth and latency, the service state further subdivides network fluctuation information to characterize the change degree of network quality indicators.

[0125] In other optional specific embodiments, the scheduling control method may not include the process of sending the first information to the near-real-time wireless intelligent controller, and only include the process of sending the second information to the near-real-time wireless intelligent controller. During the service duration, schedule and adjust in real time according to the network fluctuations to ensure that the service quality meets the service requirements.

[0126] In the case of not including the process of sending the first information to the near-real-time wireless intelligent controller, the method may not include the process of receiving the first feedback information sent by the near-real-time wireless intelligent controller, and may not involve the first feedback information either.

[0127] Optionally, before sending the second information to the near-real-time wireless intelligent controller, it further includes:

[0128] Determine whether the current network quality indicators meet the service requirements;

[0129] In the case of determining that the current network quality indicators do not meet the service requirements, generate the service adjustment instruction information.

[0130] Further optionally, determining whether the current network quality indicators meet the service requirements includes:

[0131] In the case where the network quality indicators include latency, determine whether the latency meets the service requirements according to the latency measurement information sent by the near-real-time wireless intelligent controller; the latency measurement information sent by the near-real-time wireless intelligent controller can be obtained by real-time acquisition;

[0132] When the network quality index includes bandwidth, determine the lag information of the service according to the collected network-side data, and determine whether the bandwidth meets the service requirements according to the lag information. Specifically, as Figure 4 shown, the lag situation of the service per unit time can be predicted according to the network-side data collected in real time (such as Modulation and Coding Scheme (MCS), Reference Signal Received Power (RSRP), Channel Quality Indicator (CQI), Physical Resource Block (PRB), etc.) through a machine learning model (such as a service lag prediction model), and it is judged whether the current bandwidth meets the service requirements according to the proportion of lags.

[0133] Optionally, after sending the second information to the near-real-time wireless intelligent controller, it further includes:

[0134] Receive the second feedback information sent by the near-real-time wireless intelligent controller, where the second feedback information includes a second adjustment result of scheduling adjustment according to the second information and / or status indication decision information, and the status indication decision information is used to indicate whether to re-determine the network fluctuation information.

[0135] Status indication decision: Whether the status indication information is valid, indicating whether to re-statistics the fluctuation parameters.

[0136] Wherein, the second adjustment result is used to indicate whether an adjustment has been made to the network quality index. The second feedback information may further include sensitive indication information.

[0137] After receiving the status indication decision information, the non-real-time wireless intelligent controller may determine whether to re-determine the network fluctuation information according to the status indication decision information.

[0138] In the embodiments of the present invention, although the network quality index meets the corresponding expected values, with the change of the network, the service may still experience lags and delays. Therefore, during the service duration, it is necessary to update the network fluctuation information according to the real-time delay measurement information and the predicted lag situation.

[0139] The embodiments of the present invention can be directed to services that require real-time guarantee of service quality, use the data collected in real time to obtain the real-time network quality index information of the service, and according to this information, more comprehensively depict the network quality index, give more network information to the scheduling unit, distinguish the diverse needs of the service for the network, and perform customized adjustments according to the service requirements to achieve real-time service QoS guarantee.

[0140] Please refer to Figure 5 , Figure 5 which is a schematic flowchart of a scheduling control method provided in the second embodiment of the present invention. This method is applied to a near-real-time wireless intelligent controller and includes the following steps:

[0141] Step 51: Receive the first information sent by the non-real-time wireless intelligent controller. The first information includes the expected value of the network quality indicator and the sensitive indication information. Among them, the sensitive indication information is used to indicate the network quality indicators sensitive to services, and the network quality indicators at least include one of bandwidth and delay;

[0142] Step 52: Perform scheduling adjustment according to the first information. Specifically, the near-real-time wireless intelligent controller instructs the base station to perform scheduling adjustment according to the first information. In the embodiment of the present invention, if the expected value of the network quality indicator is unreasonable, scheduling adjustment may not be performed, that is, the scheduling policy remains unchanged. In addition, the near-real-time wireless intelligent controller can also feedback to the non-real-time wireless intelligent controller the reason for not performing scheduling adjustment.

[0143] Specific scheduling adjustment schemes may include configuring semi-static scheduling, setting the Discontinuous Reception (DRX) strategy, enabling the pre-scheduling function, increasing the scheduling priority, allocating more radio resources to improve the minimum rate guarantee, temporarily configuring a custom QCI, resource reservation, etc.

[0144] For the scheduling control method provided in the embodiment of the present invention, the near-real-time wireless intelligent controller determines the network quality indicators sensitive to the current service according to the sensitive indication information sent by the non-real-time wireless intelligent controller. For example, it determines whether the network requirements of the current service are delay, bandwidth, or both, and then formulates a targeted scheduling strategy. For the network quality indicators that are not sensitive to the service, it is not necessary to ensure through scheduling adjustment, thus avoiding unnecessary scheduling adjustment for this service, reducing waste of network resources while ensuring the Quality of Service (QoS).

[0145] Optionally, after performing the scheduling adjustment according to the first information, it further includes:

[0146] Sending first feedback information to the non-real-time wireless intelligent controller. The first feedback information includes the first adjustment result of the scheduling adjustment according to the first information. The first adjustment result can be used to indicate whether the network quality indicator has been adjusted.

[0147] Optionally, determining whether to perform scheduling adjustment according to the first information includes:

[0148] Adjust the Quality of Service Class Identifier (QoS Class Identifier, QCI), and the adjusted QCI level is adapted to the expected value of the network quality index and the sensitive indication information.

[0149] There is a corresponding relationship between bandwidth, delay, and QCI level. Different QCI levels represent the size of the scheduled bandwidth and delay. Therefore, after the near-real-time radio intelligent controller receives information about bandwidth or delay, the scheduler will prioritize adjusting the QCI level.

[0150] For example, please refer to Figure 6 , if the expected value of the network quality index in the first information is the expected delay value, and the sensitive indication information is the delay-sensitive indication information indicating that the service is sensitive to delay, then the QCI of the service can be adjusted to meet the expected delay value, and the adjustment result and the delay-sensitive indication information can be put into the first feedback information and fed back to the non-real-time radio intelligent controller. Optionally, the first feedback information may further include the current delay. The non-real-time radio intelligent controller can statistically analyze the delay fluctuation based on the current delay, and can also adjust the expected delay value according to the current delay.

[0151] Please refer to Figure 7 , if the expected value of the network quality index in the first information is the expected bandwidth value, and the sensitive indication information is the bandwidth-sensitive indication information indicating that the service is sensitive to bandwidth, then the QCI of the service can be adjusted to meet the expected bandwidth value, and the adjustment result and the bandwidth-sensitive indication information can be put into the first feedback information and fed back to the non-real-time radio intelligent controller. Optionally, the first feedback information may further include the current bandwidth. The non-real-time radio intelligent controller can statistically analyze the bandwidth fluctuation based on the current bandwidth, and can also adjust the expected bandwidth value according to the current bandwidth.

[0152] Of course, in other alternative specific implementation manners, the QCI level can also be adjusted only when the sensitive indication information indicates that the target service is sensitive to both bandwidth and delay and the current QCI cannot be satisfied. If the sensitive indication information indicates that the target service is only sensitive to delay, then increase the scheduling frequency, set a short periodic scheduling strategy, or enable the pre-scheduling function. If the sensitive indication information indicates that the target service is only sensitive to bandwidth, then increase the scheduling priority and allocate more radio resources to improve the minimum rate guarantee.

[0153] In the embodiments of the present invention, the near-real-time radio intelligent controller can determine whether the network requirements of the target service are for delay, bandwidth, or both based on the sensitive indication information, and then formulate a targeted scheduling strategy. At the beginning of the service, a QCI level with a similar configuration can be selected according to the received sensitive indication information and the expected value of the network quality index. During the subsequent continuous detection process, the following scheduling adjustment strategies can be adopted:

[0154] For the latency requirement, increase the scheduling frequency, set a short-periodic scheduling strategy, or enable the pre-scheduling function;

[0155] For the bandwidth requirement, increase the scheduling priority and allocate more radio resources to improve the minimum rate guarantee;

[0156] For the bandwidth and latency requirements, when the current QCI level cannot be satisfied, temporarily configure a new QCI level, using the received expected bandwidth value and expected latency value as configuration parameters.

[0157] It should be noted that the scheduling adjustment strategies used in specific situations are not limited to those listed in the embodiments of the present invention, and the scheduling adjustment strategies used in different situations can be adjusted as needed.

[0158] Optionally, the first feedback information further includes the current network quality metric value, the current network quality metric value is used to determine network fluctuation information, and the network fluctuation information is used to indicate the degree of change of the network quality metric.

[0159] In addition, the near-real-time radio intelligent controller can also send the network quality metric value to the non-real-time radio intelligent controller multiple times, so that the non-real-time radio intelligent controller can count the changes in the network quality metric. For example, the near-real-time radio intelligent controller can send the current network quality metric value to the non-real-time radio intelligent controller in real time. Specifically, the scheduler of the near-real-time radio intelligent controller can obtain the current available bandwidth through the Media Access Control (MAC) rate of the base station, obtain the latency value through MAC latency measurement, and then send the obtained available bandwidth value and / or latency value to the non-real-time radio intelligent controller, and the non-real-time radio intelligent controller is used to count the network fluctuation information.

[0160] Optionally, the method further includes:

[0161] Receiving second information sent by the non-real-time radio intelligent controller, the second information includes service adjustment indication information and network fluctuation information, the service adjustment indication information is used to indicate adjusting the network quality metric, and the network fluctuation information is used to indicate the degree of change of the network quality metric;

[0162] Wherein, the second information may further include sensitive indication information;

[0163] Performing scheduling adjustment according to the second information.

[0164] After that, the near-real-time wireless intelligent controller may also send second feedback information to the non-real-time wireless intelligent controller. The second feedback information may include a second adjustment result of scheduling adjustment according to the second information. The second adjustment result may be used to indicate whether an adjustment has been made to the network quality index. The second feedback information may also include sensitive indication information. The second feedback information may also include status indication decision information, which is used to indicate to the non-real-time wireless intelligent controller whether to re-determine the network fluctuation information.

[0165] In the embodiments of the present invention, on the basis of indicating the expected value and network fluctuation information, in order to make timely adjustments to the service state, a new process needs to be added to carry prediction information, adjustment results, and status indication decisions. Specifically, as Figure 8 shown, the non-real-time wireless intelligent controller sends sensitive indication information, service adjustment indication information, and network fluctuation information to the near-real-time wireless intelligent controller. The near-real-time wireless intelligent controller retrieves the corresponding requirements according to the sensitive indication information and makes corresponding adjustments; after that, the near-real-time wireless intelligent controller sends sensitive indication information, adjustment results, and status indication decision information to the non-real-time wireless intelligent controller; the non-real-time wireless intelligent controller retrieves the adjustment results of the corresponding network quality index according to the sensitive indication information, and decides whether to re-statistics the network fluctuation information according to the status indication decision information.

[0166] For example, please refer to Figure 9 , the non-real-time wireless intelligent controller sends delay-sensitive indication information, delay adjustment indication, and delay variance to the near-real-time wireless intelligent controller. If the near-real-time wireless intelligent controller receives the delay adjustment indication, it increases the user scheduling frequency to reduce the delay. If the delay variance exceeds the threshold, it starts pre-scheduling and feedbacks to re-statistics the delay fluctuation information; the near-real-time wireless intelligent controller sends delay-sensitive indication information, adjustment results, and status indication decision information to the non-real-time wireless intelligent controller; the non-real-time wireless intelligent controller decides whether to re-start statistics of the delay variance according to the status indication decision information.

[0167] Please refer to Figure 10 , the non-real-time wireless intelligent controller sends bandwidth-sensitive indication information, bandwidth adjustment indication, and bandwidth variance to the near-real-time wireless intelligent controller. If the near-real-time wireless intelligent controller receives the bandwidth adjustment indication, it increases the user scheduling priority. If the bandwidth variance exceeds the threshold, it allocates a fixed part of the bandwidth for this service and feedbacks to re-statistics the bandwidth fluctuation information; the near-real-time wireless intelligent controller sends bandwidth-sensitive indication information, adjustment results, and status indication decision information to the non-real-time wireless intelligent controller; the non-real-time wireless intelligent controller decides whether to re-statistics the bandwidth variance according to the status indication decision information.

[0168] Optionally, if the service adjustment indication information is used to indicate an adjustment to the time delay;

[0169] The scheduling adjustment according to the second information includes:

[0170] If the network fluctuation information of the time delay is less than a first preset fluctuation threshold, increase the scheduling frequency or set a short-periodic scheduling strategy;

[0171] If the network fluctuation information of the time delay is greater than the first preset fluctuation threshold, initiate pre-scheduling.

[0172] The scheduler of the near-real-time radio network controller can utilize the pre-scheduling mechanism to cope with drastic fluctuations in the time delay.

[0173] Optionally, if the service adjustment indication information is used to indicate an adjustment to the bandwidth;

[0174] The scheduling adjustment according to the second information includes:

[0175] If the network fluctuation information of the bandwidth is less than a second preset fluctuation threshold, increase the scheduling priority or allocate more radio resources;

[0176] If the network fluctuation information of the bandwidth is greater than the second preset fluctuation threshold, fix at least a part of the bandwidth of the fixed service.

[0177] The scheduler of the near-real-time radio network controller can utilize the fixed bandwidth mechanism to cope with drastic fluctuations in the bandwidth.

[0178] In an embodiment of the present invention, if the requirements sent by the non-real-time radio intelligent controller are unreasonable, then the near-real-time radio intelligent controller can keep the scheduling strategy unchanged and feedback to the non-real-time radio intelligent controller the reason for the failure of the resource request.

[0179] In other optional specific embodiments, the scheduling control method may not include the process of receiving the first information sent by the non-real-time radio intelligent controller and performing scheduling adjustment according to the first information, and only includes the process of receiving the second information sent by the non-real-time radio intelligent controller and performing scheduling adjustment according to the second information. In an embodiment of the present application, during the service duration, scheduling adjustment is performed in real time for the network fluctuation situation to ensure that the service quality meets the service requirements.

[0180] In the case where the scheduling control method may not include the process of receiving the first information sent by the non-real-time radio intelligent controller and performing scheduling adjustment according to the first information, the process of sending the first feedback information to the non-real-time radio intelligent controller may not be included.
