[0003] However, since network devices cannot know whether data packets are updated during wireless network transmission, i.e., they cannot determine the information age of data packets in wireless network transmission, network devices cannot determine the extent to which the wireless network affects the information age of data packets.

[0035] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this application as detailed in the appended claims.

[0037] It should also be understood that the term "comprising" indicates the presence of the described feature, whole, step, operation, element and / or component, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements and / or components.

[0038] The following is an explanation of the terms used in this application:

[0039] Latency refers to the time delay that data takes from the sender to the receiver. In mobile communication systems, latency includes propagation latency (the time required from sending to receiving), processing latency (the time required for data to be processed in the mobile communication system), and queuing latency (the time spent waiting in the queue for transmission at network nodes in the mobile communication system). Low latency can reduce data transmission time and help improve the real-time performance of communication.

[0040] Jitter: Jitter refers to the instability or fluctuation in data transmission delay. In mobile communication systems, jitter affects the arrival time of data, potentially causing instability and latency in real-time applications. Lower jitter helps maintain communication stability and consistency.

[0041] Information age: Used to indicate the freshness of information. It can also reflect the timeliness of information status updates. This is a new area of ​​network research. A fast information status update speed does not necessarily mean that the system utilization is at its maximum when sending updated information status, nor does it necessarily mean that the system latency is at its minimum when receiving updated information status.

[0042] In one example, the information age of a data packet with timestamp u at time t is tu. At the current time t, and when the information age is zero, the current data packet is considered fresh. The information age is a stochastic process. For example, it can be: Δ(t) = tu(t).

[0043] Where Δ(t) represents the information age of the data packet. t represents the current time. u(t) is the timestamp corresponding to the time the data packet was generated.

[0044] Information age is used to represent the freshness of information. During data packet transmission over a wireless network, if the wireless network has a significant impact on the information age of the data packet, the wireless network transmission process can be optimized.

[0045] However, since network devices cannot know whether data packets are updated during wireless network transmission, i.e., they cannot determine the information age of data packets in wireless network transmission, network devices cannot determine the extent to which the wireless network affects the information age of data packets.

[0046] In view of this, embodiments of this application provide a method for determining information age performance indicators, including: obtaining the transmission and reception time and packet size of data packets within the current wireless network transmission cycle; determining the information age performance indicators of the wireless network based on the transmission and reception time and packet size; the information age performance indicators are used to indicate the degree of influence of the wireless network on the information age of data packets.

[0047] The methods provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

The message names or parameter names in the messages exchanged between the various devices in the embodiments of this application are merely examples, and other names may be used in specific implementations without limitation.

[0067] To facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" are not necessarily different.

[0068] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration.

"And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural.

For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0070] The following combination Figure 1 The system for determining information age performance indicators shown herein describes the method for determining information age performance indicators provided in the embodiments of this application.

[0071] Figure 3 This is a flowchart illustrating a method for determining information age performance indicators provided in an embodiment of this application, as shown below. Figure 3 As shown, the method includes the following steps S301-S302:

[0072] S301. Obtain the data packet transmission and reception time and average packet size (APS) within the current wireless network transmission cycle.

[0073] The duration of the wireless network transmission cycle can be set as needed. For example, it can be 1 second. The packet size is the size of the data packets received by the wireless network ingress. The unit of packet size can be bytes.

[0074] As one possible implementation, the wireless network egress and wireless network ingress of the wireless network transmission are configured with timestamp writing functionality. The information age performance index determination device can write a sending timestamp for data packets based on the wireless network egress and a receiving timestamp for data packets based on the wireless network ingress to obtain the transmission and reception times of data packets within the current wireless network transmission cycle. Furthermore, the information age performance index determination device can determine the packet size of a data packet based on the number of bytes it occupies.

[0075] As another possible implementation, the information age performance index determination device can record the packet identifier and corresponding reception time when a data packet is received at the wireless network ingress, and record the packet identifier and corresponding transmission time when a data packet is sent at the wireless network egress, in order to obtain the data packet transmission and reception time within the current wireless network transmission cycle. Furthermore, the information age performance index determination device can determine the packet size as the number of bytes occupied by the data packet.

[0076] It should be noted that the data packets refer to the data packets corresponding to the target service. For example, the public land mobile network (PLMN) identifier of the target service is the target PLMN ID, and the quality of service (QoS) level is the target QoS level.

[0077] In one example, the target PLMN ID could be 46001, etc. The target QoS level could be the target 5G QoS Identifier (5QI) level, the target QoS class identifier (QCI), etc.

[0078] In practical applications, the device for determining information age performance indicators can be a terminal device or a network device. For example, the terminal device can be... Figure 1 Terminal device 11 in the network. This network device can be Figure 1 Network device 12.

[0079] Figure 4 A schematic diagram illustrating the data packet transmission process is shown. (For example...) Figure 4 As shown, terminal devices and network devices may include a Simple Distributed File Transfer Protocol (SDAP) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a Port Physical Layer (PHY).

[0080] During the process of a terminal device sending a data packet to a network device, the entry point of the wireless network is point A. The data packet reception time is the time when the data packet arrives at point A, the data packet transmission time is the time when the data packet arrives at point C, and the packet size is the same as the data packet size at point A.

[0081] During the process of network devices sending data packets to terminal devices, the wireless network entry point is point B, which is connected to the core network. The data packet reception time is the time when the data packet arrives at point B, the data packet transmission time is the time when the data packet arrives at point D, and the packet size is the same as the data packet size at point B.

[0082] In some embodiments, the data packet transmission and reception time is the data packet transmission and reception time at the target protocol layer.

[0083] The target protocol layer includes, but is not limited to, at least one of the following: radio link control layer, media access control layer, simple distributed file transfer system access protocol layer, packet data aggregation protocol layer, port physical layer, etc.

[0084] In practical applications, the data packet corresponds to the packet-switched traffic type.

[0085] In practical applications, the network type corresponding to a wireless network can be 5G, 5G-A / 6G, etc.

[0086] S302. Determine the information age performance indicators of the wireless network based on the transmission and reception time and packet size.

[0087] Among them, the information age performance index is used to indicate the degree of influence of wireless networks on the information age of data packets.

[0088] As one possible implementation, the information age performance index determination device can determine the information age performance index of the wireless network based on the transmission and reception time and packet size when the number of data packets in the current wireless network transmission cycle exceeds a certain threshold.

[0089] The quantity threshold can be set as needed. For example, it can be 20, 50, 100, etc.

[0090] Understandably, when the number of data packets in the current wireless network transmission cycle exceeds the threshold, determining the information age performance index of the wireless network can prevent the number of data packets in the wireless network transmission cycle from being too small, thus ensuring the reliability of the information age performance index of the wireless network.

[0091] As another possible implementation, the information age performance index determination device can determine the information age performance index of the wireless network based on the transmission and reception time and packet size, assuming the number of data packets in the current wireless network transmission cycle is arbitrary.

[0092] Based on the technical solution provided in this application, the information age performance index of a wireless network is determined by the transmission and reception time and packet size of data packets within a wireless network transmission cycle. The information age performance index indicates the degree of influence of the wireless network on the information age of data packets. Since the transmission and reception time of data packets reflects the inflow and outflow status of data packets during wireless network transmission, and the inflow and outflow status as well as the segmentation status, all affect the transmission time of data packets in the wireless network. Packet size can affect data transmission efficiency and bandwidth utilization, thus affecting the transmission time of data packets in the wireless network. In this way, the impact of the wireless network on information age can be effectively reflected.

[0093] One possible implementation, Figure 5 A flowchart illustrating another method for determining information age performance indicators provided in this application embodiment is shown below. Figure 5 As shown, in order to determine the information age performance index of a wireless network, S302 in the information age performance index determination method of this application may include the following S401-S402.

[0094] S401. Determine the packet interval variation (PIV), packet delay (PD), and buffer occupancy index.

[0095] The interval time variation index indicates the fluctuation in the interval time between data packets received at adjacent times. A larger interval time variation index indicates greater fluctuation in the interval time between data packets received at adjacent times. The occupancy index indicates the occupancy of multiple data packets in the buffer.

[0096] The process of determining the interval time change index, latency, and buffer occupancy index is described below.

[0097] 1. Interval time variation index

[0098] S1. Determine the interval between consecutively received data packets.

[0099] The QoS level of the continuously received data packets is the target QoS level, and the PLMN ID is the target PLMN ID. The QoS level of the second data packet is the target QoS level, the PLMN ID is the target PLMN ID, and the slice / serving network subset identifier (S-NSSAI) is the target S-NSSAI.

[0100] As one possible implementation, the information age performance index determination device can use the average of the intervals between all consecutively received data packets as the interval between received data packets.

[0101] The average interval between all consecutively received data packets is calculated as follows: the sum of the time intervals between all data packets arriving at the system entry point (i.e., the arrival time of the next data packet minus the arrival time of the previous data packet), divided by the total number of data packets minus one.

[0102] As another possible implementation, the information age performance index determination device can randomly select the interval between two consecutively received data packets as the interval between received data packets.

[0103] In practical applications, the unit of time interval can be milliseconds.

[0104] Combination Figure 4 During the process of a terminal device sending data packets to a network device, the wireless network ingress point is point A, and the wireless network egress point is point C. The continuously received data packets are those from point A. During the process of the network device sending data packets to the terminal device, the wireless network ingress point is point B, and the wireless network egress point is point D. The continuously received data packets are those from point B.

[0105] S2. Determine the interval time variation index based on the standard deviation or rate of change of the interval time between consecutively received data packets.

[0106] In one example, the information age performance index determination device can determine the standard deviation of the interval time between consecutively received data packets as the interval time change index.

[0107] In one example, the exponent of change in time intervals satisfies the following formula:

[0108]

[0109] Wherein, PIV represents the time interval variation index. i T represents the reception time of the i-th data packet. i-1 This indicates the reception time of the (i-1)th data packet. This represents the average time interval between all consecutively received data packets. N represents the total number of data packets received within the current wireless network transmission cycle.

[0110] In another example, the information age performance index determination device can determine the rate of change of the interval time between consecutively received data packets as the interval time change index.

[0111] For example, the information age performance index determination device can determine the sum of the rates of change of the interval time between all consecutively received data packets, and determine the ratio of the sum of the rates of change to the total number of data packets minus 1 as the rate of change of the interval time between consecutively received data packets.

[0112] The measurement name for the time interval variation index can be in the format SystemEntry.PacketIntervalVariation_Filter. The filter is a combination of the PLMN ID and the QoS level.

[0113] In another example, the information age performance index determination device can determine the interval time change index by the square of the standard deviation or the square of the rate of change of the interval time between consecutively received data packets.

[0114] For example, the time interval variation index can be PIV. 2 .

[0115] In some embodiments, the information age performance index determination device can determine the interval time between consecutively transmitted data packets and determine the interval time change index based on the standard deviation or rate of change of the interval time between consecutively transmitted data packets.

[0116] The interval between consecutively sent data packets can be the average of the intervals between all consecutively sent data packets.

[0117] The average time interval between all consecutively sent data packets is calculated as follows: the sum of the time intervals between all data packets arriving at the wireless network exit (i.e., the arrival time of the next data packet minus the arrival time of the previous data packet), divided by the total number of data packets minus one.

[0118] In some embodiments, the interval variation index can be used to assess the congestion level of a wireless network and the effectiveness of traffic scheduling strategies. By monitoring changes in packet intervals within a wireless network, unstable factors in the network can be identified, thereby optimizing data transmission performance.

[0119] 2. Delay

[0120] S11. Obtain the data packet transmission and reception time within the current wireless network transmission cycle.

[0121] The data packet transmission and reception time includes the data packet reception time and the data packet transmission time.

[0122] For details on obtaining the data packet transmission and reception times within the current wireless network transmission cycle, please refer to S301, which will not be repeated here.

[0123] S12. Determine the data packet delay based on the data packet transmission and reception time within the current wireless network transmission cycle.

[0124] As one possible implementation, the information age performance index determination device can determine the average delay of multiple data packets within the current wireless network transmission cycle as the delay of the data packet.

[0125] For example, the information age performance index determination device can determine the delay of each data packet by the difference between the sending time and the receiving time of each data packet, and determine the average value of the data packets by the ratio of the sum of the delays of each data packet to the number of data packets.

[0126] As another possible implementation, the information age performance index determination device can randomly select a data packet and determine the delay of the randomly selected data packet as the delay of the data packet.

[0127] 3. Cache usage index

[0128] S21. Determine the buffer occupancy (BO) and packet size.

[0129] The packet size refers to the average size of data packets received at the wireless network ingress. Alternatively, it can be the packet size of randomly selected data packets.

[0130] As one possible implementation, the information age performance index determination device can determine the buffer occupancy rate by the ratio of the sum of the packet sizes of all data packets in the buffer to the total capacity of the buffer, and determine the packet size by the ratio of the sum of the packet sizes of the data packets received at the wireless network ingress to the number of data packets.

[0131] The measurement name for buffer occupancy can be in the format SystemEntry.BufferOccupancy_Filter. Filter represents a combination of PLMN ID and QoS level.

[0132] The format for the packet size measurement name is SystemEntry.AveragePacketSize_Filter. Filter represents a combination of PLMN ID and QoS level.

[0133] Combination Figure 4 During the process of a terminal device sending data packets to a network device, the wireless network ingress point is point A, and the wireless network egress point is point C. The packet size is the same as the packet size of the data packet at point A. During the process of the network device sending data packets to the terminal device, the wireless network ingress point is point B, and the wireless network egress point is point D. The packet size is the same as the packet size of the data packet at point B.

[0134] In some embodiments, packet size can be used for wireless network resource optimization (such as bandwidth allocation). By monitoring the average packet size at the wireless network ingress point, data transmission efficiency and bandwidth utilization can be assessed.

[0135] In some embodiments, buffer occupancy can be used for network traffic management. By monitoring buffer occupancy, the load on the wireless network and the effectiveness of traffic scheduling strategies can be assessed.

[0136] S22. Determine the cache occupancy index based on the ratio of cache occupancy to packet size.

[0137] For example, the cache occupancy index can be

[0138] Where APS represents packet size, and BO represents cache utilization.

[0139] S402. Determine the information age performance index based on the interval time change index, latency, and buffer occupancy index.

[0140] As one possible implementation, the information age performance index determination device can determine the information age performance index by summing the interval time change index, latency, and buffer occupancy index.

[0141] As another possible implementation, the information age performance index determination device can perform weighted processing on the interval time change index, latency and buffer occupancy index based on preset weights, and determine the weighted result as the information age performance index.

[0142] For example, the information age performance index can be represented by the following formula:

[0143]

[0144] Among them, FAC AOI This represents the information age performance index. α represents the preset weight of the interval time change index, β represents the preset weight of the buffer occupancy index, and g represents the preset weight of the latency.

[0145] It should be noted that the specific values ​​of α, β, and g can be determined according to needs. For example, they can be 0.4, 0.3, and 0.3 respectively, or 0.3, 0.4, and 0.3, etc.

[0146] Understandably, the interval time variation index reflects the stability of a wireless network. A larger interval time variation index indicates poorer network stability, increasing the information age and thus affecting its age. Similarly, greater transmission latency also increases the information age, impacting its overall age. The buffer occupancy index considers buffer occupancy and packet size. Higher buffer occupancy indicates longer packet wait times in the network, increasing the information age. Larger average packet sizes directly impact buffer occupancy, further affecting information age. Therefore, by comprehensively considering the interval time variation index, buffer occupancy index, and latency, a more comprehensive measure can be taken of the impact of wireless network transmission on information age.

[0147] In one possible embodiment, the method for determining the information age performance index in this application may further include the following S501.

[0148] S501. If the information age performance index is greater than or equal to the first threshold, adjust the target service corresponding to the data packet.

[0149] The first threshold can be set as needed. For example, it can be 1, etc.

[0150] As one possible implementation, the information age performance index determination device can adjust the target service corresponding to the data packet according to the target strategy.

[0151] It should be noted that the target strategy includes at least one of the following:

[0152] The priority of the target business is adjusted from the first priority to the second priority; the second priority is greater than the first priority.

[0153] The number of transmission resources for the target service is adjusted from the first resource quantity to the second resource quantity; the second resource quantity is greater than the first resource quantity.

[0154] The signal-to-interference-plus-noise ratio (SINR) of the target service is adjusted from the first SINR value to the second SINR value; the second SINR value is less than the first SINR value.

[0155] The network used by the target service is changed from the first network to the second network; the information age performance index of the second network is lower than that of the first network.

[0156] In one example, the information age performance index determination device can execute the first target strategy in the above target strategy if the information age performance index is greater than or equal to the first threshold, and execute the second target strategy within a preset time after executing the first target strategy if the information age performance index is still greater than or equal to the first threshold, until the information age performance index is still less than the first threshold.

[0157] The first objective strategy is any one of multiple objective strategies. The second objective strategy is different from the objective strategy.

[0158] If the information age performance index is still greater than or equal to the first threshold within a preset time period after executing any target strategy, multiple target strategies can be executed until the information age performance index is still less than the first threshold.

[0159] For example, the information age performance index determination device can first select two target strategies. If the information age performance index is still greater than or equal to the first threshold within the preset time of executing the two target strategies, then execute more target strategies (such as three, four, etc.) until the information age performance index is still less than the first threshold.
