[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311249872.7 filed in China on September 26, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to a clock system feedback method, apparatus, terminal, network equipment, and storage medium. Background Art

[0004] Among the related protocols, the Time-Sensitive Network (TSN) based on the 5th Generation Mobile Communication Technology (5G) system can provide time synchronization services. In the TSN network, feedback on the Radio Access Network (RAN) side for burst arrival time offset and adjusted periodicity is proposed.

[0005] The relevant technologies are mainly targeted at services such as extended reality, which are not very sensitive to latency requirements (~10ms). In addition, extended reality services have the characteristics of periodicity and variable burst size. Therefore, the relevant technologies cannot adapt to the deterministic and highly latency-sensitive characteristics of TSN networks, resulting in frequent adjustments to the arrival time or cycle of service flows on the core network side.

[0111] In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0112] Before describing the specific embodiments of the present disclosure, the following description is first given:

[0113] When the Next Generation Radio Access Network (NG-RAN) receives Time Sensitive Communication Assistance Information (TSCAI) including a Burst Arrival Time (BAT) window or the ability to adjust BAT based on a Quality of Service (QoS) flow or a period range based on a QoS flow, or when the NG-RAN finds that a QoS flow cannot meet the established protocol packet delay budget (PDB), the NG-RAN can inform the core network side of the burst arrival time compensation, which is used by the core network side to adjust the arrival time or period of the service flow to match the expected later transmission opportunity of the air interface.

[0114] In order to solve the problem in related technologies that the core network side frequently adjusts the arrival time or period of the service flow, the embodiments of the present disclosure provide a clock system feedback method, apparatus, terminal, network equipment and storage medium.

[0115] As shown in FIG1 , an embodiment of the present disclosure provides a clock system feedback method, which is applied to a terminal. The method includes:

[0116] Step 101: Send target information related to feedback from the radio access network RAN ​​side to a network device, where the target information includes at least one of the following: service burst arrival time compensation; an adjustable period; and a change value of the adjustable period.

[0117] It should be noted that the network device is a base station.

[0118] In this step, the service burst arrival time compensation is the time compensation between the service burst arrival time and the next expected air interface transmission opportunity, including the time compensation between the uplink service burst arrival time and the next expected air interface transmission opportunity, and the time compensation between the downlink service burst arrival time and the next expected air interface transmission opportunity.

[0119] In an optional embodiment of the present disclosure, the method further includes:

[0120] The terminal receives the target configuration information sent by the network device. Specifically, the network device sends the target configuration information to the terminal through Radio Resource Control (RRC) signaling;

[0121] Sending targeted information related to RAN side feedback to network devices, including:

[0122] The terminal sends the target information to the network device according to the target configuration information, wherein the target configuration information includes at least one of the following items, that is, the network device configures the terminal with one or more of the following configurations through RRC signaling:

[0123] a service burst arrival time compensation threshold (or RAN side burst arrival time compensation threshold), wherein when the service burst arrival time compensation in the target information reaches the threshold, the terminal performs reporting of the service burst arrival time compensation;

[0124] an adjustable period threshold (or referred to as a RAN side period threshold), where when the adjustable period in the target information reaches the adjustable period threshold, the terminal performs reporting of the adjustable period;

[0125] a change threshold value of the adjustable period (or called a RAN side period change threshold value), where when the change value of the adjustable period in the target information reaches the change threshold value of the adjustable period, the terminal reports the change value of the adjustable period;

[0126] First configuration information of a reporting timer, wherein the terminal performs reporting of the target information within the start time of the reporting timer indicated by the first configuration information, that is, during the period when the reporting timer is started, the terminal performs feedback reporting of the target information, and when the reporting timer expires, the terminal stops performing feedback reporting of the target information;

[0127] Second configuration information of a prohibition timer, wherein the terminal does not perform reporting of the target information within the activation time of the prohibition timer indicated by the second configuration information, and the prohibition timer is used to prevent instantaneous jitter from causing the core network side to frequently adjust the service burst arrival time or / and the service flow cycle. When the prohibition timer is started, feedback reporting of the target information is stopped within the activation time of the prohibition timer;

[0128] a first counting threshold, wherein when the service burst arrival time compensation in the target information exceeds the service burst arrival time compensation threshold and the number of times of exceeding reaches the first counting threshold, the terminal performs reporting of the service burst arrival time compensation; optionally, when the service burst arrival time compensation exceeds the service burst arrival time compensation threshold and the number of consecutive times of exceeding is greater than the first counting threshold, the terminal performs reporting of the service burst arrival time compensation;

[0129] The second counting threshold. When the adjustable period in the target information exceeds the service burst and exceeds the adjustable period threshold value, and the number of exceedances reaches the second counting threshold, the terminal reports the adjustable period. Optionally, when the adjustable period exceeds the service burst and exceeds the adjustable period threshold value, and the continuous number of exceedances reaches the second counting threshold, the terminal reports the adjustable period;

[0130] The third counting threshold. When the change value of the adjustable period in the target information exceeds the change threshold value of the adjustable period, and the number of exceedances reaches the third counting threshold, the terminal reports the change value of the adjustable period. Optionally, when the change value of the adjustable period exceeds the change threshold value of the adjustable period, and the continuous number of exceedances reaches the third counting threshold, the terminal reports the change value of the adjustable period. Among them, the above first counting threshold, second counting threshold and third counting threshold are used to prevent the core network side from frequently adjusting the service burst arrival time and / or the period of the service flow caused by instantaneous jitter;

[0131] At least one service burst arrival time compensation interval and an index value corresponding to each service burst arrival time compensation interval. The service burst arrival time compensation interval is determined according to the service burst arrival time compensation maximum value, service burst arrival time compensation minimum value and step size, and the index values are numbered from small to large. Each index value corresponds to a service burst arrival time compensation interval. Exemplarily, the service burst arrival time compensation maximum value is Tmax, the service burst arrival time compensation minimum value is Tmin, and the step size is step1. Then the service burst arrival time compensation intervals are obtained as T1, T2, T3..., where T1 < T2 < T3..., that is, at least one service burst arrival time compensation interval and an index value corresponding to each service burst arrival time compensation interval are configured in the following format: [INDEX1 T1], [INDEX2 T2], [INDEX3 T3]..., INDEX1, INDEX2, INDEX3... are index values numbered from small to large;
