Background

With the development and wide application of mobile internet technology, more and more devices are accessed into a mobile network, and new services and applications are layered endlessly. In order to meet the communication demands of people, the fifth generation mobile communication technology (abbreviated as 5G or 5G technology) has become a hot spot for research and study in the communication industry and academia. The fifth generation mobile communication technology is the latest generation cellular mobile communication technology, and its performance targets are high data rate, reduced delay, energy saving, reduced cost, improved system capacity, and large-scale device connection.

HDRLL introduces many new QoS (Quality of Service) challenges in 5G communications, such as problems like picture lag, audio loss, etc. when an end-side user moves, for several of the scenarios listed above. In addition, poor connection of the air interface and traffic congestion may be causes of the above problems.

In the interest of clarity and conciseness, not all features of an embodiment are described in the specification.

In this disclosure, the terms "first," "second," and the like are used merely to distinguish between elements or steps and are not intended to indicate a chronological order, preference, or importance.

Currently, 5G communication can be applied to various applications, such as XR, cloud gaming, remote driving, toD, etc., among others, and a completely new HDRLL (high data rate and low latency) scenario/service is proposed. One of the big characteristics of HDRLL services is that the peak-to-average ratio (peak-to-average ratio) of the data transmission rate is very high, and the scenarios/services such as XR, closed gap, toD will face big data rate fluctuations, and a big system tolerance is required for real-time data rate fluctuations. Thus, AF (Application Function) in a 5G network requires adjustment of the data transmission rate over a large fluctuation range during communication to provide the network with better rate adaptation capability. Typically, however, the capability of AF is limited, particularly in monitoring and predicting data rate changes in 5G networks. There is therefore a need to provide a reliable mechanism to help the AF be able to quickly adapt to dynamically changing data rates and hence QoS requirements updates.

To facilitate an understanding of the context of the present disclosure, the basic architecture of a 5G network and QoS in 5G communications will be briefly described below.

The 5G network architecture mainly comprises a 5G access network and a 5G core network, wherein NG-RAN stands for 5G access network, mainly comprises various nodes, such as a gNB and a NG-eNB, etc., which can communicate with user equipments, terminal equipments, etc. The 5GC represents a 5G core network comprising the presence of various core network elements such as AF (Application Function ), AMF (Access and Mobility Management Function, access and mobility management function), UPF (User Plane Function ), SMF (Session Management Function, session management function), PCF (Policy Control Function ) and the like. These network elements may be implemented in various implementations, but in a typical implementation they may be implemented as functional modules, e.g., as physical implementations, or as virtualized implementations, or as functions of the network element implemented by a device, e.g., a processor, not necessarily as physical implementations.

In order to provide different quality of service for different services, wireless networks provide QoS (Quality of Service ) management mechanisms, which are control mechanisms by which the wireless network meets different quality of service requirements, which may relate to data rates, transmission delays, bit error rates, etc. In 5G-NR, qoS is implemented at QoS flow level, and in particular, qoS configuration (QoS Profile) of QoS flows may include notification control (notification control) to indicate whether or not a reporting message is required to notify the core network when GFBR cannot be satisfied in an active period of QoS flows of GFBR (Granted Flow Bit rate, guaranteed flow bit rate).

A conceptual flowchart of notification control in a QoS flow in the related art will be briefly described below with reference to fig. 1.

In case the GBR QoS flow starts the notification control, the NG-RAN, e.g. the gNB, may determine the GFBR of the current QoS flow, e.g. based on the current system load or based on a measure of the queue delay, or if the PDB (Packet Delay Budget ) and PER (Packet Error Rate, packet error rate) of the QoS configuration can be met, if not, i.e. "GFBR cannot be guaranteed", the NG-RAN will send a notification to the SMF. In addition, although notification is made, the NG-RAN attempts to maintain the connection, in particular, needs to continue to maintain the QoS flow (i.e., maintain the QoS configuration of the QoS flow that does not currently meet the traffic requirements). Under certain specific conditions, such as RLF (Radio Link Failure ) or intra-RAN congestion, the NG-RAN may release the radio resources currently occupied by the GBR QoS flows.

On the other hand, the SMF forwards the notification to the PCF and then to the AF for the 5G core network to process the GBR QoS flow accordingly. For example, the core network adjusts control parameters for the corresponding QoS flows and provides the adjusted control parameters to the NG-RAN to update operations so that QoS is satisfied.

From the above, it can be seen that, in the existing QoS parameters of 5GS, notification control is generated only by NG-RAN under the condition that "GFBR cannot be guaranteed, or cannot be guaranteed currently but may be guaranteed again" appears in the life cycle of one QoS flow, and the core network is triggered to perform parameter adjustment. However, when GFBR or PDB or PER cannot meet the current service requirements in terms of data rate, and/or transmission delay, and/or bit error rate, and the like, then requesting the core network to adjust the parameter configuration of the corresponding QoS flow by triggering data rate adaptation is delayed for the service with high delay requirements, because NG-RAN still keeps the QoS configuration parameters of the current QoS flow to communicate, and RLF or data congestion is most likely to be generated on the access side, so that data transmission is significantly affected.

In view of this, the present disclosure proposes an early warning mechanism capable of notifying a network side (e.g., a core network such as notifying a control side device in the core network) of information indicating a trend of change in data communication, particularly information indicating that a data communication condition may be deteriorated, by means of an early notification, which is preferably performed earlier than the notification control in the related art, and may be performed in various suitable manners, for example, may be performed in a manner similar to the notification control or signaling, but is performed before the notification control. When the data communication condition may deteriorate, the network side may make configuration preparation for rate matching adaptation and necessary QoS configuration update in advance so as to update the communication configuration parameters, particularly QoS configuration-related parameters, and feed back the updated parameters to the access side device, for example, before or after "data communication condition deterioration, cannot be guaranteed" in trigger notification control in the related art. Fig. 2 shows a conceptual flow diagram of an early warning mechanism according to an embodiment of the present disclosure.

Thus, the core network device can learn about the data communication condition earlier, and can make update preparation of the QoS configuration in advance in the case where the data communication condition may be degraded. But also reliable connection maintenance of the network, especially of the NG-RAN to the core network, is achieved because the QoS configuration is adjusted in time so that the NG-RAN does not have to keep the old QoS configuration operating as in the notification control mode, resulting in long-term degradation of data communication, such as radio link failure, data congestion, etc.

Embodiments according to the present disclosure will be described in detail below. Typically, a wireless communication system or radio system comprises at least an access side and a control side. In this disclosure, an "access side" has its full breadth of common meaning, generally referring to the side of a system that can access/connect to a communication network for communication operations. The "control side" has the full breadth of its usual meaning and accordingly may instruct the side of the system that receives information provided by the access side for corresponding control/processing of its communication operations. In the present disclosure, the access side device may inform the control side device of relevant information such as a data communication condition in the access side, based on which the control side device performs control such as configuration parameter adjustment or the like and feeds back to the access side device, so that the access side device can perform communication based on control of the control side device accordingly.

In the present disclosure, an "access side" device may include a transmitting side device and a receiving side device in a wireless communication system, between which communication can be performed through transmission and reception of a signal stream. And they are both able to acquire the communication conditions in the access side and inform the core network in an appropriate way.

The transmitting-side devices may include various suitable devices such as base stations, control devices, servers or MECs, repeaters or roadside units (RSUs), and the like in wireless communication systems such as cellular communication systems, V2X systems, and the like. In this disclosure, the term "base station" has its full breadth of common meaning, and as an example, a base station may be an eNB compliant with the 4G communication standard, a gNB compliant with the 5G communication standard, a remote radio head, a wireless access point, an aircraft control tower, or a communication device performing similar functions.

The receiving side device may comprise various suitable devices, which may accordingly comprise terminal devices in the communication system. In the present disclosure, the term "terminal device" has its full breadth of its usual meaning and includes at least a terminal device that receives a signal from a transmitting-side device as part of a wireless communication system or radio system to facilitate communication. As examples, the terminal device may be, for example, a terminal device such as a wireless relay, a micro base station, a router, a user equipment, or the like, or a communication apparatus performing similar functions. In this disclosure, "terminal device" and "User Equipment (UE)" may be used interchangeably, or "terminal device" may be combined with or implemented as part of "user equipment". In the present disclosure, the term "User Equipment (UE)" has the full breadth of its usual meaning, and as an example, the user equipment may be a terminal device such as a mobile phone, a laptop, a tablet, an in-vehicle communication device, or the like, or a communication apparatus performing similar functions.

In the present disclosure, the control-side device may include any suitable device in the network, such as other devices in addition to the transmitting-side device and the receiving-side device. For example, in a 5G network implementation, the control-side device may be implemented by an appropriate function/unit/module/device or the like in the 5G core network, e.g. corresponding to AF in the 5G core network.

A control-side electronic device of a wireless communication system according to an embodiment of the present disclosure will be described below. The control-side electronic device is capable of communicating with an access-side electronic device in a wireless communication system, in particular, acquiring information related to a data communication condition provided by the access-side electronic device, and controlling/adjusting parameters related to the data communication based thereon.

According to an embodiment of the present disclosure, a control-side electronic device includes a processing circuit configured to: acquiring indication information of a data communication condition change trend in a wireless communication system under the condition that the data communication condition in the wireless communication system meets the communication quality requirement; adjusting a related parameter for data communication of the access side electronic device in a case where the acquired indication information indicates that the data communication in the wireless communication system may be degraded; and informing the access side electronic equipment of the adjusted communication configuration parameters.

According to embodiments of the present disclosure, the data communication status in the wireless communication system may refer to a data communication status in an access side in the wireless communication system, and in particular, may refer to a data communication status between a transmitting side electronic device and a terminal side electronic device, for example, between a base station and a UE, for example, uplink communication or downlink communication, and the like. By way of example, the communication conditions may include, or be indicated by, data transmission rates, end-to-end delays, packet jitter, etc.

According to the embodiments of the present disclosure, the information indicating the trend of the data communication condition change may be information of the fluctuation of the data rate. According to some embodiments of the present disclosure, the information of the data rate fluctuation may refer to information that can be used to indicate or judge a trend of change of the data rate. Based on this it can be determined whether such a rate change results in a communication condition no longer meeting the communication quality requirements. As an example, large data rate fluctuations may indicate that the data communication conditions may be degraded, e.g., the communication quality requirements may not be met/guaranteed.

In some embodiments, communication quality requirements may refer to quality of service (QoS) related requirements, such as data rate, transmission delay, bit error rate, and so forth. In particular, the satisfaction of the communication quality requirement of the data communication condition in the wireless communication system may mean that in the data communication between the access side devices in the wireless communication system, the above requirements can be satisfied, for example, the requirements of the data rate, the transmission delay, the bit error rate, and the like can be satisfied/ensured. As an example, in the 5G rule, the following QoS parameters related to QoS flows are also defined: guaranteed traffic bit rate (GFBR: guaranteed Flow Bit Rate), which may be suitable for both upstream and downstream communications, relates to traffic associated with both upstream and downstream, such as guaranteed traffic or maximum traffic. Thus, the communication quality requirement may refer to a GFBR related requirement. Of course other requirements are possible, such as PBR, PER etc.

According to an embodiment of the present disclosure, the access side electronic device includes a transmission side electronic device and a terminal side electronic device, and the information of the data rate fluctuation of the data communication may be acquired and provided to the control side electronic device by at least one of the transmission side electronic device and the terminal side electronic device, or may be acquired and provided to the control side electronic device by a device other than the transmission side electronic device and the terminal side electronic device in the access side. As an example, the information of the data rate fluctuation may be reported by one or both of the base station and the UE. As one example, the reporting may be by the corresponding party for different traffic types. For example, downlink traffic may be reported by the UE and uplink traffic may be reported by the base station. As another example, both parties may report the same traffic type. For example, both parties report in parallel. For example, for downlink traffic, the UE may report the AF directly, the base station detects a rate change based on the downlink traffic feedback from the UE to the base station, and reports the information to the AF.

According to embodiments of the present disclosure, whether the indication information indicates that data communication in the wireless communication system may be degraded may be determined by various suitable means. In some embodiments, the indication information may be compared to a particular threshold to make a determination, for example, in the case where the indication information includes a fluctuation in data rate, the communication condition may be considered to be degraded when the fluctuation in data rate is greater than the particular threshold, for example, the communication quality may be degraded in the future although the current communication quality is satisfactory.

In some embodiments, the determination of the fluctuation of the data rate, i.e. whether the fluctuation of the data rate exceeds a certain threshold, may be performed by the control side electronics. In this way, the information of the data rate fluctuation may be information directly detected by the access side and transmitted to the control side electronic device without being screened. For example, by an access-side electronic device, such as a transmitting-side electronic device and/or a receiving-side electronic device or other devices on the access side, indication information of the trend of the data communication condition on the access side is acquired and the acquired information is directly transmitted to a control-side electronic device for operation by the control-side electronic device. In this case, the information may be in various suitable forms, in particular a numerical value indicating a fluctuation of the data rate. As an example, the base station/UE may report the detection result directly without making a decision. For example, the change may be reported to the AF, which may then determine whether the change requires QoS adjustments.

In other embodiments, the determination of the fluctuation of the data rate, i.e. whether the fluctuation of the data rate exceeds a certain threshold, may be performed by the access side electronic device. In this way, the access side electronic device detects the data rate fluctuation condition, and transmits information of the data rate fluctuation to the control side electronic device only in the case where it is judged that the data rate fluctuation is greater than a specific threshold. For example, a detected fluctuation in rate by a base station/UE may be reported when the detected fluctuation/change exceeds a certain threshold, and subsequent detection may be stopped.

In this case, the acquired indication information of the trend of the change in the data communication condition in the wireless communication system itself indicates that the data communication condition may be degraded, and in this case, the information may be represented by various suitable means, for example, may be indicated by a binary indicator or bit, one value indicating the presence of such indication information that the communication condition may be degraded and the other value indicating the absence, so that the communication condition is judged by detecting the value of such indicator. In another example, the information may also correspond to a specific indicator or field that when present in the information transmitted from the access side to the control side indicates that the communication condition may be degraded, such that the communication condition may be determined by detecting the presence of such an indicator or bit.

According to some embodiments of the present disclosure, the control side device performs parameter control/adjustment based on information of the data rate fluctuation and provides feedback. In particular, the control-side electronic device adjusts communication configuration parameters regarding data communication on the access side based on the information of the data rate fluctuation, and feeds back such adjusted communication configuration parameters to the access-side device so that the communication quality requirements can be satisfied when the access-side device operates based on the adjusted communication configuration parameters. According to some embodiments of the present disclosure, the communication configuration parameters for data communication with the access side electronic device may be any suitable parameters, such as QoS configuration related parameters in a 5G communication scenario. For example, information on QoS configuration for the transmitting-side electronic device and the terminal-side electronic device may be mentioned.

As an example, the base station/UE uploads the acquired rate fluctuation information to the AF, and then the AF sets an appropriate QoS configuration according to the uploaded information and then allocates to the base station and UE. In particular, the base stations and UEs that communicate with each other are paired, so QoS configurations are provided for both paired base stations and UEs, and are the same QoS configuration. As an example, feedback may be provided through a connection interface between the network access side and the core network, or the QoS configuration may be informed to both the base station and the UE, or to one of the base station or the UE, and to the other of the base station or the UE.

Therefore, according to the embodiments of the present disclosure, the control-side electronic device can acquire the indication information of the trend of the communication condition change in the case where the data communication condition is still satisfying the communication quality requirement in the wireless communication system, and adjust and inform the access-side electronic device of the parameter of the communication regarding the access-side electronic device in the case where it is judged that the communication condition may become deteriorated based on the indication information, so that the access-side electronic device can adjust the operation in time so that the communication condition can satisfy the quality requirement without performing parameter adjustment after the communication condition has been deteriorated as in the conventional operation, thereby effectively avoiding possible communication quality deterioration such as wireless link failure or congestion, and optimizing the wireless communication quality.

The acquisition of the indication information of the communication condition variation trend according to the embodiment of the present disclosure will be described below taking the data rate fluctuation as an example. According to some embodiments, the data rate fluctuations may be statistical information of the data rate in the data communication. In one embodiment, the data rate fluctuations may be obtained by directly performing rate statistics. For example, rate statistics may be performed by counting data (in bytes/second or bits/second) that is successfully received per unit time, and counting data rate changes over a certain period of time. As an example, the information of the data rate fluctuation may be statistical information referring to a difference between a maximum value and a minimum value of the data rate in a specific period of time. Such as a data rate change value when the data rate is monotonically changing (such as monotonically increasing or monotonically decreasing) over a particular time, or data fluctuation statistics such as variance, mean, median, etc. in the case of non-monotonic changes. In some embodiments, the data rate fluctuations may also be measured by means of other indicators. As an example, fluctuations in data rate (equivalent to fluctuations in traffic) may be counted by real-time packet delay and/or packet error rate values.

According to some embodiments, the information of the fluctuation of the data rate may be obtained by setting a time window corresponding to the specific time period and making statistics of the data rate within the time window. As an example, the time length of the time window may be set appropriately in advance.

In some embodiments, the setting information of the time window may be added to the communication configuration parameters as new parameter information, e.g. as new parameter fields, parameter bits, etc.

In some embodiments, the setting information of the time window may be set in an existing communication configuration parameter, for example, the time window for acquiring information of the data rate fluctuation may be set by means of an existing parameter field or the like. As an example, qoS parameters 5QI (5G QoS Indicator) related to QoS flows are also currently defined in the 5G communication rule, including average window (average window) parameters related to notification control, the average window being, for example, 2000ms, GFBR and MFBR (Maximum Flow Bit Rate, maximum traffic bit rate) calculated during the window period being effective for triggering an update of QoS configuration caused by the notification control. In the present disclosure, the average window parameter may be multiplexed to set a time window for acquiring information of data rate fluctuation, and a window period of data rate fluctuation statistics is also defined within the average window, so that the rate fluctuation of the current time period may be counted while GFBR and MFBR are calculated. According to some embodiments, the time length of the time window for acquiring the information of the data rate fluctuation, i.e. the aforementioned specific time period, is not greater than the time length of the average window.

In this case, the information of the data fluctuation acquired through the time window can still be transmitted to the control side independently of the procedure of the notification control of QoS. In particular, the notification control may be triggered to transmit information in the event that a data fluctuation exceeding a threshold is detected, but not earlier than the notification control triggered when the determination GFBR in the conventional is not guaranteed. For example, the NG-RAN may trigger an early warning if it determines that the trend of data rate fluctuations exceeds a certain threshold, i.e., while the GFBR may still remain in a certain state.

In some embodiments, the time window for data rate statistics may be a plurality of sub-windows. As an example, the sum of the time lengths of these sub-windows is not greater than the time length of the average window. In particular, the data rate fluctuation is generally caused by dynamic changes of services or changes of mobility and participation quantity of users, and the statistics time is too long, so that local large fluctuation can be averagely and unrealistically reflected. It is possible to use a segment statistics method to make statistics on whether the data rate change reaches the early warning condition, where the time window for making the data rate statistics is a sub-window of the average window or a window segment, as shown in fig. 4A. The window segments may be serial window segments/sub-windows, which may be continuous or discontinuous. Their lengths are typically set to be the same as each other. These windows may be used as data rate monitoring windows to monitor and report data rate changes during the windows to the control side device. The early warning condition may be defined herein as a percentage in which the data rate change in any one of the windows counted (e.g., 330 ms) exceeds a fixed threshold, or at least a percentage in which the statistical average across the sub-window exceeds a threshold.

In some embodiments, the time window for data rate statistics may be a single window equal to or less than the average window, as shown in fig. 4B. As an example, in the case of data rate fluctuation monitoring by applying an averaging window, different frequencies may be set to realize different functions. For example, the frequency for monitoring the data rate fluctuation may be set to a frequency different from, and generally higher than, the frequency of the QoS parameter calculation. Thus, communication can be performed with higher frequency communication signaling different from QoS, enabling data rate fluctuation monitoring in an average window.

According to an embodiment of the present disclosure, in the case where the time window for data rate statistics multiplexes the average window in the existing 5QI, the average window is not necessarily completely used up. Because of the notification of the early warning class information, the feedback related to this type is not limited by the window period used for notification control, which may lead to untimely data feedback to the AF. Thus, for example, if an abnormal state is found in the sub-window period of the average window once the fluctuation of the traffic data rate is counted, the notification control may be triggered to feed back the trend information to the AF. This case may be equivalent to the notification control being triggered at any time, not just at a preset period. Of course, the processing on the AF side is also different from the processing mode after the conventional notification control is received. In contrast, upon receiving feedback exceeding the guard line, the AF side immediately performs a corresponding QoS configuration update policy.

According to some embodiments of the present disclosure, the information of the data rate fluctuation may be acquired periodically, for example, in acquiring the rate fluctuation in a specific period of time according to a specific period. As an example, the UE and NG-RAN may pre-configure the GBFR and measurement period of the data rate fluctuation in advance. The configuration period of the two measurements may be different, and the measurement period of GBFR does not need to be too short, for example, it may be configured for 10s. Because the statistics of the data rate change are to be early-warned, more frequent measurement periods, such as 5s or less, can be properly configured.

In other embodiments, the information of the data rate fluctuation may be acquired on request, for example, upon request of the control side electronic device, and provided to the control side electronic device after acquisition.

Adjustment/configuration of communication configuration parameters by the control-side electronic device according to an embodiment of the present disclosure will be described below.

According to some embodiments of the present disclosure, the control-side electronic device adjusts or configures the communication configuration parameters such that the communication quality requirements can be met when the access-side electronic device performs data communication based on the adjusted or configured parameters.

In some embodiments, a mapping relationship between data rate fluctuations and data communication configuration parameters, such as QoS configuration, may be preset, where a data rate fluctuation value may correspond to a communication configuration parameter that enables data communication to become more stable and meet communication requirements. The control side electronic device can select the data communication configuration parameters corresponding to the threshold value according to the received data rate fluctuation and provide the data communication configuration parameters to the access side electronic device.

As an example, the AF may set a mapping of rate fluctuation and QoS configuration, that is, a correspondence list of rate fluctuation and QoS configuration is preset, and select an updated QoS configuration, for example, a QoS configuration with a priority level adjusted, according to the correspondence list. As an example, the mapping relationship between the data rate fluctuation and the priority level of QoS configuration may be as shown in the following table:

5QI	default priority level	Data rate fluctuation
			1	20	-20Mbps～+20Mbps
2	40	-10Mbps～+10Mbps
			3	30	-5Mbps～+5Mbps

As another example, the data rate early alert is independent of the QoS notification control, and the AF may pre-configure the data rate list so that the NG-RAN and UE attach additional data rate expectations at the time of early warning, and the data rate list and QoS flows have a mapping relationship table on the AF, PCF side, so that the appropriate QoS configuration may be selected with reference to the relationship table.

As yet other examples, the AF sends allocation information regarding air interface resources, including but not limited to adjustment of scheduling weights, to the NG-RAN via the PCF according to the QoS configuration list request and the data rate fluctuation status.

According to the embodiment of the disclosure, the control side electronic device may also acquire expected communication configuration parameters of the transmitting side electronic device and the terminal side electronic device. In this case, the control-side electronic device may determine the final communication configuration parameter from both the received data rate fluctuation and the expected communication configuration parameter. In particular, the communication configuration parameters may be determined based on the received rate fluctuations and the final communication configuration parameters to be adjusted may be selected in combination with the communication configuration parameters expected by the transmitting-side electronic device and the terminal-side electronic device. As an example, the desired communication configuration parameter may be directly selected as the final communication configuration parameter. As another example, a higher priority communication configuration parameter of the two may be selected as the final communication configuration parameter. As yet another example, a more appropriate communication configuration parameter may be selected as the final communication configuration parameter in accordance with network factors such as network load balancing, resource utilization efficiency, and the like.

In some embodiments, the expected communication configuration parameters may be set based on rate fluctuations. For example, the expected communication configuration parameters are set by the transmitting-side electronic device and/or the terminal-side electronic device based on the rate fluctuation and reported together with the rate fluctuation. In some embodiments, the expected communication configuration parameters may be configuration parameters suitable for future potentially changing traffic. For example, the expected communication configuration parameters are set by the transmitting-side electronic device and/or the terminal-side electronic device by referring to future possible changes of the service in order to make the subsequent operation more suitable for future services.

In some embodiments, the expected communication configuration parameters are higher priority communication configuration parameters determined by the access side electronic device based on the indication information. Of course, the expected communication configuration parameters may be set by devices other than the transmitting-side electronic device and the terminal-side electronic device based on the rate fluctuation, and inform the transmitting-side electronic device and the terminal-side electronic device. Or may be reported directly to the control side electronic device by the other device.

As an example, in addition to reporting rate fluctuations, the base station/UE may also report updated QoS configurations based on rate fluctuation settings that the base station/UE itself has selected. As another example, the base station/UE may also report alternative QoS parameters suitable for future potentially changing traffic to the control side electronics. As an example, when the NG-RAN pre-configures the available QoS configuration, the NG-RAN may refer to a higher priority QoS configuration among the available QoS configurations as a desired QoS configuration or a recommended QoS configuration while performing early warning, and report the relevant information to the control-side device.

On the other hand, when the information reported by the base station/UE further includes the information of the QoS configuration recommended by the base station/UE, the AF may select the QoS parameters of the network from the recommended QoS configuration. Or the AF may adjust the QoS configuration according to the information of the data rate fluctuation and select a more appropriate QoS configuration from the adjusted QoS configuration and the recommended QoS configuration to feed back to the access side device.

In some embodiments, for each uploading party, a parameter only for the uploading party, namely, a special QoS configuration, i.e. a recommended QoS configuration for the uploading party, may be selected, or a unified QoS configuration may be set by comprehensively considering information uploaded by a plurality of base stations/UEs in the network.

According to the embodiments of the present disclosure, when information of data rate fluctuation is received from both the transmitting-side device and the receiving-side device included in the access-side device, determination of the communication configuration parameters can be made based on both. The report from one party can be used as an evidence of the other party. For example, after receiving a report from one party, a report from the other party may be received by waiting a certain time, and if not, the communication configuration parameters may not be adjusted. If received, the appropriate communication configuration parameters are selected according to different requirements of the transmitting-side device and the receiving-side device, instead of setting the communication configuration parameters according to only one party.

According to some embodiments of the present disclosure, in the early warning mechanism of the present disclosure, the control side electronic device may adjust the communication configuration parameter and feed it back to the access side device upon determining that the communication condition will be degraded, independently of the conventional notification control triggered when the communication quality requirement cannot be satisfied. Its feedback may be earlier or later than the notification control.

As an example, feedback of AF may be fed back to UE/base station before QoS notification control, which may effectively avoid QoS notification control. According to the embodiment of the disclosure, the feedback of the AF may also return to the UE/base station after the QoS notification control is performed, so that after the base station/UE performs QoS parameter adjustment, the feedback result of the QoS notification control may not be considered any more even if the feedback result of the QoS notification control is received again.

According to some embodiments of the present disclosure, the control side electronic device may employ an implicit feedback mechanism, that is, in a case where the control side electronic device determines that the acquired data rate fluctuation is not greater than a specific threshold, that is, in a case where it is determined that the data communication will not be degraded in the future, feedback is not provided any more. Correspondingly, a feedback waiting window exists on the side of the access side electronic equipment, and once the feedback receiving window is over, the access side electronic equipment keeps maintaining the original parameters of QoS configuration.

As can be seen from the above, according to the embodiments of the present disclosure, when the acquired information of the fluctuation of the data rate, for example, the data rate fluctuation data is higher than a specific threshold, it is considered that the fluctuation of the data rate is aggravated, and serious fluctuation may occur to affect communication, so that early warning will be triggered, and when such early warning is triggered, the communication condition between the transmitting-side electronic device and the terminal-side electronic device is still stable, so that the data communication is improved.

The control side electronics of the wireless communication system according to embodiments of the present disclosure, and in particular the processing of the same, may be implemented in a variety of suitable ways. In the above described structural examples of the apparatus, the processing circuit may be in the form of a general-purpose processor or may be a dedicated processing circuit, such as an ASIC. For example, the processing circuit can be constructed of circuitry (hardware) or a central processing device, such as a Central Processing Unit (CPU). Further, the processing circuit may have a program (software) for causing a circuit (hardware) or a central processing apparatus to operate.

In actual implementation, each unit described above may be implemented as an independent physical entity, or may be implemented by a single entity (e.g., a processor (CPU or DSP, etc.), an integrated circuit, etc.). It should be noted that although each unit is illustrated as a separate unit in fig. 3, one or more of the units may be combined into one unit or split into a plurality of units. Furthermore, the various units described above are shown in dashed lines in the figures to indicate that these units may not actually be present, and that the operations/functions they implement may be implemented by the processing circuitry itself.

It should be understood that fig. 3 is merely a schematic structural configuration of the control side electronic device in the wireless communication system, and the control side electronic device 300 may alternatively include other components not shown, such as a memory, a radio frequency link, a baseband processing unit, a network interface, a controller, and the like.

A method for a control side of a wireless communication system according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings, and fig. 5 shows a flowchart of a method 500 for a control side of a wireless communication system according to an embodiment of the present disclosure.

It should be noted that these steps may be performed by the control side electronics according to the present disclosure as described hereinbefore, in particular by the respective units of the control side electronics according to the present disclosure as described hereinbefore.

An access side electronic device of a wireless communication system according to an embodiment of the present disclosure will be described below. The access side may be a party in the wireless communication system that receives downlink communication and/or initiates uplink communication, and may be appropriately selected according to a signal transmission direction in a wireless communication scenario, for example, when downlink communication is performed from a base station to a user terminal, the access side may refer to a user terminal side, and when downlink communication is performed from other devices to a base station in the wireless communication system, the access side may refer to the base station side. It should be noted that the access side sub-device may correspond to the device in the wireless communication system that communicates in the communication scenario (such as an access point, a user terminal, etc. in the communication system) itself or an electronic device used in conjunction with the device.

Fig. 6 shows a block diagram of an access side electronic device according to an embodiment of the disclosure. The access side electronic device 600 is capable of communicating with a control side electronic device in a wireless communication system, and the access side electronic device 600 includes a processing circuit 602 configured to acquire, in a case where a data communication condition in the wireless communication system satisfies a communication quality requirement, indication information of a trend of a change in the data communication condition in the wireless communication system; the indication information is transmitted to the control side electronic device, and communication configuration parameters adjusted based on the indication information in a case where the acquired indication information indicates that data communication in the wireless communication system may be degraded are received from the control side electronic device.

In some embodiments, the processing circuit is further configured to send the indication information to the control-side electronic device only if the indication information is greater than a particular threshold.

In some embodiments, the processing circuit is further configured to send expected communication configuration parameters of the access side electronic device to the control side electronic device. The expected communication configuration parameters herein may be determined as described above.

It should be noted that the terminal-side electronic device 600 may be implemented in various suitable ways, and in particular may be implemented in a similar way as the control-side electronic device 300. For example, various units may be included to realize the foregoing operations/functions, such as the acquisition unit 604 configured to acquire the indication information of the trend of the data communication condition change in the wireless communication system in the case where the data communication condition in the wireless communication system satisfies the communication quality requirement; a transmitting unit 606 configured to transmit the instruction information to the control-side electronic device, and a receiving unit 608 configured to receive a communication configuration parameter from the control-side electronic device that is adjusted based on the instruction information in a case where the acquired instruction information indicates that data communication in the wireless communication system may be degraded. Furthermore, the processing circuitry 602 may also include memory, which may be external to the processing circuitry or even external to the access side electronics.

A method for a wireless communication system access side according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings, and fig. 7 shows a flowchart of a method 700 for a wireless communication system access side according to an embodiment of the present disclosure.

In step S701 (referred to as an acquisition step), in the case where the data communication condition in the wireless communication system satisfies the communication quality requirement, instruction information of the trend of the data communication condition in the wireless communication system is acquired;

in step S702 (referred to as a transmitting step), the instruction information is transmitted to the control-side electronic device, and

in step S703 (referred to as a receiving step), a communication configuration parameter adjusted based on the acquired instruction information in a case where the acquired instruction information indicates that data communication in the wireless communication system may be degraded is received from the control-side electronic device.

Furthermore, the method may further comprise respective steps of implementing the operations performed by the terminal-side electronic device described above. It should be noted that these steps may be performed by the access side electronic device according to the present disclosure as described hereinbefore, in particular by the respective units of the access side electronic device according to the present disclosure as described hereinbefore.

One exemplary implementation of the present disclosure is described below primarily based on a 5G network, but it should be understood that aspects of the present disclosure are equally applicable to other similar communication networks, wireless communication networks, etc., as long as transmission quality requirements exist in these networks and early warning concepts may be applied to optimize data transmission. Fig. 8 shows an example of early warning of data rate fluctuations in accordance with the present disclosure, where the comparison between the two is also made with reference to a conventional notification control flow.

When the NG-RAN measures a monotonically fluctuating change (e.g., monotonically increasing or decreasing) in data rate over a certain time range and exceeds a certain threshold over a statistical time range, it illustrates that the data rate fluctuation early warning signaling may be generated due to a change in data rate demand caused by a change in traffic itself or the number of UEs in a connected state. It should be noted that the signaling may be coupled or independent of the notification control. Because the premise of generating notification control is that the NG-RAN detects that the GFBR cannot be guaranteed or can be guaranteed next time, the data rate fluctuation early warning is an early warning mechanism just under the condition that the GFBR can be guaranteed. Therefore, if notification control is used, a new condition "GFBR is about to be unable to be guaranteed" or "GFBR is temporarily satisfied as described in the flowchart, but may not be guaranteed" is required, and notification control signaling of the new condition is sent to a core network, for example, an SMF network element, together with a quantized value of change information, and decision rights that data rate adaptation or QoS configuration needs to be made in advance are given to AF through a path of SMF-PCF-AF inside the core network.

AF utilizes built-in AI algorithm to dynamically adjust data rate matching according to NG-RAN feedback rate change state, if necessary, qoS configuration updated for the same QoS flow is generated, and corresponding parameters are issued to NG-RAN to realize early update or reserve update of QoS dynamic adjustment.

Specifically, when the NG-RAN does not configure the candidate QoS configuration, after the AF receives the information pushed by the PCF, the AF finds out the QoS configuration with higher priority matching the original QoS flow from the corresponding relationship between the pre-stored data rate list and the QoS configuration contained in the QoS flow. And the AF sends the QoS configuration adjustment information and the scheduling information of the corresponding air interface resources to the NG-RAN through the SMF. And after the NG-RAN receives the information, the NG-RAN schedules the users needing the current business service through the updated scheduling strategy. When the NG-RAN is configured with the candidate QoS configuration, the NG-RAN includes, in the data rate fluctuation early warning information, the QoS configuration with the highest priority (the data rate fluctuation and QoS configuration correspondence table is preconfigured to the user) closest to the possible service QoS to be switched, the AF performs corresponding rate adaptation and early (timing) update preparation of the QoS configuration, for example, the candidate QoS configuration sent by the NG-RAN may be directly selected, or the QoS configuration may be determined by itself, and a more appropriate QoS configuration is selected from among the self-determined QoS configuration and the candidate QoS configuration, and this information is fed back to the NG-RAN through the SMF.

Furthermore, although an example in which the data rate fluctuation information is reported by the NG-RAN to the AF in the core network is shown here, the conventional notification control mechanism is that the NG-RAN issues the result that the QoS configuration does not satisfy the requirement to the SMF network element of the core network. Considering that the requirement of data rate fluctuation on real-time performance is high, besides the statistics of the rate fluctuation can be sent to the SMF by the NG-RAN, the UE can also send the statistics to the SMF by the NAS layer signaling assistance through a corresponding interface, for example, an N1 interface, as shown in fig. 9. It should be noted that the expression "N-number" in fig. 9 indicates a connection/interface between elements/components in the communication system, and that abbreviations (e.g., AF, NSSF, AMF, etc.) indicating the elements/components in fig. 9 may have meanings known in the art, such as those in the 5G communication system, which will not be described in detail herein.

Different from the prior art, here, the reporting body of the uplink and downlink data can be distinguished. For example, considering that the receiving end of the service communication is generally the fastest with data rate variation, we can specify that the statistical reporting of the uplink data rate variation is performed by NG-RAN, and the statistical reporting of the downlink data rate variation is performed by UE. It also supports both uplink and downlink to complete statistics and reporting by one party (NG-RAN or UE).

In summary, according to the comparison between the data rate dynamic adjustment early-updating and the traditional notification control in the present disclosure, it can be seen that, with the assistance of the data rate early-warning mechanism in the present disclosure, the core network AF network element can learn the air interface state reflected by the NG-RAN earlier, so as to achieve QoS configuration update preparation in advance, and also achieve reliable connection maintenance from the NG-RAN to the core network, because the QoS configuration is adjusted in time, the RAN side will not generate RLF due to long-time big data congestion.

It should be noted that the above description is merely exemplary. Embodiments of the present disclosure may also be implemented in any other suitable manner, while still achieving the advantageous effects obtained by embodiments of the present disclosure. Moreover, embodiments of the present disclosure are equally applicable to other similar application examples, and still achieve the advantageous effects obtained by the embodiments of the present disclosure.

It should be understood that machine-executable instructions in a machine-readable storage medium or program product according to embodiments of the present disclosure may be configured to perform operations corresponding to the above-described apparatus and method embodiments. Embodiments of a machine-readable storage medium or program product will be apparent to those skilled in the art when referring to the above-described apparatus and method embodiments, and thus the description will not be repeated. Machine-readable storage media and program products for carrying or comprising the machine-executable instructions described above are also within the scope of the present disclosure. Such a storage medium may include, but is not limited to, floppy disks, optical disks, magneto-optical disks, memory cards, memory sticks, and the like.

In addition, it should be understood that the series of processes and devices described above may also be implemented in software and/or firmware. In the case of implementation by software and/or firmware, a program constituting the software is installed from a storage medium or a network to a computer having a dedicated hardware structure, such as the general-purpose personal computer 1600 shown in fig. 10, which is capable of executing various functions and the like when various programs are installed. Fig. 10 is a block diagram showing an example structure of a personal computer of an information processing apparatus employable in an embodiment of the present disclosure. In one example, the personal computer may correspond to the exemplary purchasing side electronic device or the selling side electronic device described above according to the present disclosure.

In fig. 10, a Central Processing Unit (CPU) 1601 performs various processes according to a program stored in a Read Only Memory (ROM) 1602 or a program loaded from a storage section 1608 to a Random Access Memory (RAM) 1603. In the RAM 1603, data required when the CPU 1601 executes various processes and the like is also stored as needed.

The CPU 1601, ROM 1602, and RAM 1603 are connected to each other via a bus 1604. An input/output interface 1605 is also connected to the bus 1604.

The following components are connected to the input/output interface 1605: an input section 1606 including a keyboard, a mouse, and the like; an output section 1607 including a display such as a Cathode Ray Tube (CRT), a Liquid Crystal Display (LCD), etc., and a speaker, etc.; a storage section 1608 including a hard disk or the like; and a communication section 1609 including a network interface card such as a LAN card, a modem, and the like. The communication section 1609 performs communication processing via a network such as the internet.

The driver 1610 is also connected to the input/output interface 1605 as needed. A removable medium 1611 such as a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is installed as needed on the drive 1610, so that a computer program read out therefrom is installed into the storage section 1608 as needed.

In the case of implementing the above-described series of processes by software, a program constituting the software is installed from a network such as the internet or a storage medium such as the removable medium 1611.

It will be appreciated by those skilled in the art that such a storage medium is not limited to the removable medium 1611 shown in fig. 9, in which the program is stored, which is distributed separately from the apparatus to provide the program to the user. Examples of the removable medium 1611 include a magnetic disk (including a floppy disk (registered trademark)), an optical disk (including a compact disk read only memory (CD-ROM) and a Digital Versatile Disk (DVD)), a magneto-optical disk (including a Mini Disk (MD) (registered trademark)), and a semiconductor memory. Alternatively, the storage medium may be a ROM 1602, a hard disk contained in the storage section 1608, or the like, in which a program is stored, and distributed to users together with a device containing them.

The techniques of this disclosure can be applied to a variety of products.

For example, the access side electronic device according to the embodiments of the present disclosure may be implemented as or included in various control devices/base stations. For example, the transmitting apparatus and the terminal apparatus according to the embodiments of the present disclosure may be implemented as or included in various terminal apparatuses.

For example, the control devices/base stations mentioned in this disclosure may be implemented as any type of base station, e.g., enbs, such as macro enbs and small enbs. The small enbs may be enbs that cover cells smaller than the macro cell, such as pico enbs, micro enbs, and home (femto) enbs. Also for example, it may be implemented as a gNB, such as a macro gNB and a small gNB. The small gnbs may be gnbs that cover cells smaller than the macro cell, such as pico gnbs, micro gnbs, and home (femto) gnbs. Instead, the base station may be implemented as any other type of base station, such as a NodeB and a base transceiver station (Base Transceiver Station, BTS). The base station may include: a main body (also referred to as a base station apparatus) configured to control wireless communication; and one or more remote radio heads (Remote Radio Head, RRH) disposed at a different location than the main body. In addition, various types of terminals, which will be described below, may operate as a base station by temporarily or semi-permanently performing a base station function.

For example, the terminal devices mentioned in this disclosure may be implemented in some embodiments as mobile terminals (such as smartphones, tablet Personal Computers (PCs), notebook PCs, portable gaming terminals, portable/dongle-type mobile routers and digital cameras) or vehicle-mounted terminals (such as car navigation devices). Terminal devices may also be implemented as terminals performing machine-to-machine (M2M) communication (also referred to as Machine Type Communication (MTC) terminals). Further, the terminal device may be a wireless communication module (such as an integrated circuit module including a single wafer) mounted on each of the above terminals.

An application example according to the present disclosure will be described below with reference to the accompanying drawings.

[ example about base station ]

It should be understood that the term base station in this disclosure has its full breadth of ordinary meaning and includes at least a wireless communication station that is used to facilitate communication as part of a wireless communication system or radio system. Examples of base stations may be, for example, but are not limited to, the following: a base station may be one or both of a Base Transceiver Station (BTS) and a Base Station Controller (BSC) in a GSM system, one or both of a Radio Network Controller (RNC) and a Node B in a WCDMA system, an eNB in an LTE and LTE-Advanced system, or a corresponding network Node in a future communication system (e.g., a gNB, an LTE eNB, etc. that may occur in a 5G communication system). Some of the functions in the base station of the present disclosure may also be implemented as entities having a control function for communication in D2D, M M and V2V communication scenarios, or as entities playing a role in spectrum coordination in cognitive radio communication scenarios.

First example

Fig. 11 is a block diagram showing a first example of a schematic configuration of a gNB to which the techniques of the present disclosure may be applied. The gNB 1700 includes a plurality of antennas 1710 and a base station device 1720. The base station apparatus 1720 and each antenna 1710 may be connected to each other via an RF cable. In one implementation, the gNB 1700 (or base station device 1720) herein may correspond to the control side electronic device described above.

Each of the antennas 1710 includes a single or multiple antenna elements, such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna, and is used for the base station device 1720 to transmit and receive wireless signals. As shown in fig. 11, the gNB 1700 may include a plurality of antennas 1710. For example, the multiple antennas 1710 may be compatible with multiple frequency bands used by the gNB 1700.

The base station device 1720 includes a controller 1721, a memory 1722, a network interface 1717, and a wireless communication interface 1725.

The controller 1721 may be, for example, a CPU or DSP, and operates various functions of higher layers of the base station apparatus 1720. For example, the controller 1721 determines the location information of the target terminal device among the at least one terminal device based on the location information of the at least one terminal device on the terminal side and the specific location configuration information of the at least one terminal device in the wireless communication system acquired by the wireless communication interface 1725. The controller 1721 may have a logic function to perform control as follows: such as radio resource control, radio bearer control, mobility management, access control and scheduling. The control may be performed in conjunction with a nearby gNB or core network node. The memory 1722 includes a RAM and a ROM, and stores programs executed by the controller 1721 and various types of control data (such as a terminal list, transmission power data, and scheduling data).

The network interface 1723 is a communication interface for connecting the base station apparatus 1720 to the core network 1724. The controller 1721 may communicate with a core network node or another gNB via a network interface 1717. In this case, the gNB 1700 and the core network node or other gNB may be connected to each other through logical interfaces (such as S1 interface and X2 interface). The network interface 1723 may also be a wired communication interface or a wireless communication interface for a wireless backhaul. If the network interface 1723 is a wireless communication interface, the network interface 1723 may use a higher frequency band for wireless communication than the frequency band used by the wireless communication interface 1725.

The wireless communication interface 1725 supports any cellular communication schemes, such as Long Term Evolution (LTE) and LTE-Advanced, and provides wireless connectivity to terminals located in a cell of the gNB 1700 via the antenna 1710. The wireless communication interface 1725 may generally include, for example, a baseband (BB) processor 1726 and RF circuitry 1727. The BB processor 1726 may perform, for example, encoding/decoding, modulation/demodulation, and multiplexing/demultiplexing, and various types of signal processing of layers such as L1, medium Access Control (MAC), radio Link Control (RLC), and Packet Data Convergence Protocol (PDCP). Instead of the controller 1721, the bb processor 1726 may have some or all of the logic functions described above. The BB processor 1726 may be a memory storing a communication control program, or a module including a processor configured to execute a program and related circuits. The update program may cause the functionality of BB processor 1726 to change. The module may be a card or blade that is inserted into a slot of the base station apparatus 1720. Alternatively, the module may be a chip mounted on a card or blade. Meanwhile, the RF circuit 1727 may include, for example, a mixer, a filter, and an amplifier, and transmit and receive a wireless signal via the antenna 1710. Although fig. 11 shows an example in which one RF circuit 1727 is connected to one antenna 1710, the present disclosure is not limited to this illustration, but one RF circuit 1727 may be connected to a plurality of antennas 1710 at the same time.
