[0041] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the attached claims.

[0043] It should also be understood that the term “comprising” indicates the presence of described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements and / or components.

[0044] The following is an explanation of the terms involved in this application:

[0045] Latency: Latency refers to the time delay experienced by data from the sender to the receiver. In mobile communication systems, latency includes propagation delay (the time required from sending to receiving), processing delay (the time required for data to be processed in the mobile communication system) and queuing delay (the time network nodes in the mobile communication system queue up for transmission). Low latency can reduce the data transmission time and help improve the real-time performance of communication.

[0046] Jitter: Jitter refers to the instability or fluctuation of data transmission delay. In mobile communication systems, jitter affects the time interval between data arrivals, which may cause instability and delays in real-time applications. Smaller jitter helps maintain stability and consistency of communication.

[0047] Information age: used to indicate the freshness of information. It can also reflect the timeliness of the information status update. This is a new field of network research. When the information status is updated quickly, it does not mean that the system utilization rate is the maximum utilization rate when sending the updated information status, nor does it mean that the system delay is the minimum delay when receiving the updated information status.

[0048] In one example, the information age of a data packet with timestamp u at time t is tu. When the current time is t and the information age is zero, the current data packet is considered fresh. The information age is a random process. For example, it can be: Δ(t) = tu(t).

[0049] Where Δ(t) represents the information age of the data packet. t represents the current time. u(t) is the timestamp corresponding to the generation time of the data packet.

[0050] Information age is used to indicate the freshness of information. During the transmission of data packets over a wireless network, if the wireless network has a significant impact on the information age of the data packets, the wireless network transmission process can be optimized.

[0051] However, since the network device cannot know whether the data packet is updated during wireless network transmission, that is, it cannot determine the information age of the data packet during wireless network transmission, the network device cannot determine the extent of the impact of the wireless network on the information age of the data packet.

[0052] In view of this, an embodiment of the present application provides a method for determining an information age performance index, including: obtaining the sending and receiving time and segment sequence number of a data packet within the current wireless network transmission cycle; determining the information age performance index of the wireless network based on the sending and receiving time and the segment sequence number; the information age performance index is used to indicate the degree of influence of the wireless network on the information age of the data packet.

[0053] The method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0054] It should be noted that the network system described in the embodiment of the present application is to more clearly illustrate the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application.

[0069] As an optional implementation, the information age performance indicator determination device 200 includes multiple processors, for example, Figure 2 In addition to the processor 201, a processor 205 may also be included.

[0070] It should be pointed out that Figure 2 The composition shown in the Figure 1 The limitations of each device in Figure 2 In addition to the parts shown, Figure 1 The individual devices in the Figure 2 More or fewer components, or combinations of certain components, or different arrangements of components.

[0071] In the embodiment of the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0072] In addition, the actions, terms, etc. involved in the various embodiments of the present application can refer to each other without limitation. The message name or parameter name in the message exchanged between the various devices in the embodiments of the present application is only an example, and other names can also be used in the specific implementation without limitation.

[0073] In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish the same or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit the difference.

[0074] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0075] In the present application, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0076] Combine the following Figure 1 The information age performance index determination system shown describes the information age performance index determination method provided in the embodiment of the present application.

[0077] Figure 3 A flow chart of a method for determining an information age performance index provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the method includes the following S301-S302:

[0078] S301: Obtain the sending and receiving time and segment sequence number of the data packet in the current wireless network transmission cycle.

[0079] The duration of the wireless network transmission cycle can be set as needed. For example, it can be 1 second. The data packet includes a first data packet passing through the wireless network entrance and a second data packet passing through the wireless network exit. The second data packet is obtained by segmenting the first data packet. The segment sequence number is used to characterize the preset order of sending data packets. The smaller the segment sequence number, the earlier the preset order of sending data packets.

[0080] As a possible implementation, the wireless network exit and wireless network entrance of the wireless network transmission are configured with a timestamp writing function, and the information age performance index determination device can write a sending timestamp for the data packet based on the wireless network exit and write a receiving timestamp for the data packet based on the wireless network entrance to obtain the sending and receiving time of the data packet in the current wireless network transmission cycle. Further, the data packet is parsed at the wireless network exit to obtain the segment sequence number of the data packet.

[0081] As another possible implementation, the information age performance indicator determination device can record the identifier and corresponding reception time of the data packet when receiving the data packet at the wireless network entrance, and record the identifier and corresponding transmission time of the data packet when sending the data packet at the wireless network exit, so as to obtain the transmission and reception time of the data packet in the current wireless network transmission cycle. Furthermore, the data packet is parsed at the wireless network exit to obtain the segment sequence number of the data packet.

[0082] It should be noted that the data packet is a data packet corresponding to the target service. For example, the public land mobile network identifier (PLMN ID) of the target service is the target PLMN ID, and the quality of service (QoS) level is the target QoS level.

[0083] In one example, the target PLMN ID may be 46001, etc. The target QOS level may be a target 5G quality of service identifier (5G QoS Identifier, 5QI) level, a target quality of service level (QoS class identifier, QCI), etc.

[0084] In practical applications, the information age performance indicator determination device can be a terminal device or a network device. Figure 1 The terminal device 11 in the network device can be Figure 1 The network device 12 in.

[0085] Figure 4 FIG. 1 is a schematic diagram showing a data packet transmission process. Figure 4 As shown, the terminal device and the network device may include a simple distributed file transfer system access protocol (simplifiedfs access protocol, SDAP) layer, a packet data convergence protocol (packet data convergence protocol, PDCP) layer, a radio link control (radio link control, RLC) layer, a medium access control Layer (medium access control Layer, MAC) layer, and a port physical layer (physical, PHY).

[0086] When the terminal device sends a data packet to the network device, the wireless network entrance is point A. The receiving time of the data packet is the time when the data packet arrives at point A, the sending time of the data packet is the time when the data packet arrives at point C, and the segment number is the segment number of the data packet at point C.

[0087] When a network device sends a data packet to a terminal device, the wireless network entrance is point B, which is connected to the core network. The receiving time of the data packet is the time when the data packet arrives at point B, the sending time of the data packet is the time when the data packet arrives at point D, and the segment number is the segment number of the data packet at point D.

[0088] In some embodiments, the time of sending and receiving a data packet is the time of sending and receiving the data packet at the target protocol layer.

[0089] Among them, the target protocol layer includes but is not limited to at least one of the following: radio link control (RLC) layer, medium access control (MAC) layer, simple distributed file transfer system access protocol layer, packet data convergence protocol layer, port physical layer, etc.

[0090] In actual applications, the data packet corresponds to the applicable traffic type of packet switching traffic.

[0091] In actual applications, the network type corresponding to the wireless network can be 5G, 5G-A / 6G, etc.

[0092] S302: Determine the information age performance index of the wireless network according to the sending and receiving time and the segment sequence number.

[0093] The information age performance index is used to indicate the influence of the wireless network on the information age of the data packet.

[0094] As a possible implementation, the information age performance index determining device may determine the information age performance index of the wireless network according to the sending and receiving time and the segment sequence number when the number of data packets in the current wireless network transmission cycle is greater than the number threshold.

[0095] The quantity threshold can be set as needed, for example, 20, 50, 100, etc.

[0096] It can be understood that when the number of data packets in the current wireless network transmission cycle is greater than the number threshold, determining the information age performance indicator of the wireless network can avoid the number of data packets in the wireless network transmission cycle being too small and ensure the reliability of the information age performance indicator of the wireless network.

[0097] As another possible implementation, the information age performance index determining device may determine the information age performance index of the wireless network according to the sending and receiving time and the segment sequence number when the number of data packets in the current wireless network transmission cycle is any number.

[0098] Based on the technical solution provided by the present application, the information age performance index of the wireless network is determined by the sending and receiving time and segment sequence number of the data packet within the wireless network transmission cycle. The information age performance index is used to indicate the degree of influence of the wireless network on the information age of the data packet. Since the sending and receiving time of the data packet can reflect the inflow and outflow status of the data packet during the wireless network transmission process, and the segment sequence number can reflect the segmentation status of the data packet during the wireless network transmission process. The inflow and outflow status and the segmentation status both affect the transmission time of the data packet in the wireless network, and the transmission time of the data packet in the wireless network is positively correlated with the information age of the data packet. In this way, the influence of the wireless network on the information age can be effectively reflected.

[0099] A possible embodiment, Figure 5 A flowchart of another method for determining information age performance indicators provided in an embodiment of the present application is shown as follows: 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 the present application may include the following S401-S402.

[0100] S401: Determine a congestion index, a segmentation index, and a disorder index of a data packet.

[0101] Among them, the congestion index is used to indicate the congestion status of wireless network transmission; the fragmentation index is used to indicate the degree to which the data packet is fragmented; and the disorder index is used to indicate the disorder degree of the data packet sending order.

[0102] The processes of determining the congestion index, segmentation index and disorder index are introduced below.

[0103] 1. Congestion Index

[0104] S1. Determine the exit interval time and the entrance interval time.

[0105] The ingress interval is the interval between consecutively received first data packets; the egress interval is the interval between consecutively sent second data packets.

[0106] The QOS level of the first data packet 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 / service network subset identifier (single networkslice selection assistance information, S-NSSAI) is the target S-NSSAI.

[0107] As a possible implementation, the information age performance indicator determination device may use the average of the interval times between all consecutively received first data packets as the entry interval time, and use the average of the interval times between consecutively sent second data packets as the exit interval time.

[0108] The mean of the interval time between all consecutively received first data packets is calculated as follows: the sum of the time intervals for all data packets to arrive at the system entrance (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.

[0109] The mean of the interval time between all consecutively sent second data packets is calculated as follows: the sum of the time intervals for all data packets to arrive at the system 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.

[0110] In practical applications, the units of the egress interval time and the ingress interval time may be milliseconds.

[0111] The measurement name of the entry interval time may be in the format of SystemEntry.PacketIntervalAvg_Filter. Filter represents a combination of PLMN ID and QoS level.

[0112] The format of the measurement name of the exit interval time is SystemExit.PacketIntervalAvg_Filter. Filter represents the combination of PLMN ID, QoS level and S-NSSAI.

[0113] Combination Figure 4 , in the process of the terminal device sending a data packet to the network device, the wireless network entrance is point A and the wireless network exit is point C. The first data packet is the data packet at point A, and the second data packet is the data packet at point C. In the process of the network device sending a data packet to the terminal device, the wireless network entrance is point B and the wireless network exit is point D. The first data packet is the data packet at point B, and the second data packet is the data packet at point D.

[0114] In some embodiments, the purpose of measuring the ingress interval time and the egress interval time is to ensure performance (user plane connection quality) within the integrity region and to evaluate the congestion level of the network and the effectiveness of the traffic scheduling strategy.

[0115] S2. Determine a congestion index according to the difference between the exit interval time and the entrance interval time.

[0116] In one example, the information age performance index determination device may determine the difference between the exit interval time and the entrance interval time as the congestion index.

[0117] For example, the congestion index may be PIntAExi - PintAEntry.

[0118] Among them, PIntAExi represents the exit interval time (also can be expressed as Exit.PacketIntervalAvg), and PintAEntry represents the entry interval time (also can be expressed as Entry.PacketIntervalAvg).

[0119] In another example, the information age performance index determining device may determine the square of the difference between the exit interval time and the entrance interval time as the congestion index.

[0120] For example, the congestion index can be |(PIntAExi-PIntAEntry)| 2 .

[0121] 2. Segment Index

[0122] S11. Determine a segment distance of the second data packet and a segment number of the first data packet.

[0123] The segment distance is the sending time difference between second data packets with adjacent sequence numbers.

[0124] As a possible implementation, the information age performance indicator determination device may use the average of the transmission time differences between all second data packets with adjacent sequence numbers as the segment distance of the second data packets, and use the average of the number of segmentations of all first data packets as the exit interval time.

[0125] The calculation method of the average of the sending time differences between all the second data packets with adjacent sequence numbers is as follows: the sum of the sending time differences between all the second data packets with adjacent sequence numbers is divided by the total number of segmentation times.

[0126] The calculation method of the average of the number of fragmentation of all the first data packets is: divide the sum of the number of fragmentation of all the first data packets by the total number of the first data packets.

[0127] The measurement name of the segment distance may be in the format of: PacketSegmentationDistanceAvg_Filter. Filter represents a combination of PLMN ID, QoS level, and S-NSSAI.

[0128] The measurement name of the number of segmentations of the first data packet can be in the format of: PacketSegmentationAvg

[0129] _Filter. Filter represents the combination of PLMN ID, QoS level and S-NSSAI.

[0130] Combination Figure 4 , in the process of the terminal device sending a data packet to the network device, the wireless network entrance is point A and the wireless network exit is point C. The second data packet is the data packet at point C, and the number of segments of the first data packet is determined according to the number of segments of the data packet at point C. In the process of the network device sending a data packet to the terminal device, the wireless network entrance is point B and the wireless network exit is point D. The second data packet is the data packet at point D, and the number of segments of the first data packet is determined according to the number of segments of the data packet at point D.

[0131] In some embodiments, the segment distance of the second data packet and the number of segmentations of the first data packet are used to evaluate the performance and quality of the network. A higher average number of segmentations and a larger segment distance may indicate network congestion or other problems, which require further analysis and optimization.

[0132] S12. Determine a segmentation index according to the product of the segmentation distance of the second data packet and the number of segmentations of the first data packet.

[0133] As a possible implementation manner, the information age performance indicator determination device may determine the product of the segmentation distance of the second data packet and the number of segmentations of the first data packet as the segmentation index.

[0134] For example, the segment index may be PSegA×PSegDisA.

[0135] Wherein, PSegA indicates the number of segments of the first data packet, and PintAEntry indicates the segment distance of the second data packet.

[0136] 3. Out-of-order index

[0137] S21. Determine the proportion of out-of-order data packets and the out-of-order distance.

[0138] The out-of-order data packet is a data packet with abnormal transmission order. The out-of-order distance is the difference in sequence numbers between second data packets with adjacent transmission times.

[0139] As a possible implementation method, the information age performance indicator determination device may use the number of all out-of-order data packets and the total number of data packets as the ratio of out-of-order data packets, and use the average of the out-of-order distances of all data packets as the out-of-order distance.

[0140] The calculation method of the mean out-of-order distance of all data packets is as follows: the sum of the mean out-of-order distances of all data packets is divided by the total number of data packets.

[0141] It should be noted that, for each second data packet sent, when the sequence number of the second data packet is smaller than the sequence number of the previous data packet of the second data packet, the second data packet is determined to be an out-of-sequence data packet.

[0142] The measurement name format of the proportion of out-of-order packets may be: PacketDisorderAvg_Filter. Filter represents a combination of PLMN ID, QoS level, and S-NSSAI.

[0143] The measurement name format of the disorder distance is PacketDisorderAvgDistance_Filter. Filter represents the combination of PLMN ID, QoS level and S-NSSAI.

[0144] Combination Figure 4 , in the process of the terminal device sending a data packet to the network device, the wireless network entrance is point A and the wireless network exit is point C. The second data packet is the data packet at point C. The proportion of out-of-order data packets is the proportion of out-of-order data packets at point C (it can also be the proportion of out-of-order data packets counted at point D), and the out-of-order distance is determined based on the data packet at point C (it can also be determined based on the data packet at point D). In the process of the network device sending a data packet to the terminal device, the wireless network entrance is point B and the wireless network exit is point D. The second data packet is the data packet at point D. The proportion of out-of-order data packets is the proportion of out-of-order data packets at point D (it can also be the proportion of out-of-order data packets counted at point C), and the out-of-order distance is determined based on the data packet at point D (it can also be determined based on the data packet at point C).

[0145] In some embodiments, the proportion of out-of-order packets and the out-of-order distance are used to evaluate network performance and quality. The proportion of out-of-order packets and the out-of-order distance reflect the stability of the arrival order of packets in wireless network transmission, which can help identify network congestion or other problems.

[0146] S22. Determine an out-of-order index according to the product of the proportion of out-of-order data packets and the out-of-order distance.

[0147] As a possible implementation manner, the information age performance index determination device may determine the product of the proportion of out-of-order data packets and the out-of-order distance as the out-of-order index.

[0148] For example, the segment index may be PSegDisorderA×PSegDisorderDisA.

[0149] PSegDisorderA indicates the proportion of out-of-order packets, and PSegDisorderDisA indicates the out-of-order distance.

[0150] S402: Determine information age performance index according to the congestion index, segmentation index and disorder index.

[0151] As a possible implementation manner, the information age performance index determination device may determine the sum of the congestion index, the segmentation index and the disorder index as the information age performance index.

[0152] As another possible implementation, the information age performance index determination device may perform weighted processing on the congestion index, the segmentation index and the disorder index based on preset weights, and determine the weighted processing result as the information age performance index.

[0153] For example, the information age performance index can be expressed by the following formula 1:

[0154] FAC AOI =α×|(PIntAExi-PIntAEntry)| 2 +β×PSegA×PSegDisA+ɡ×

[0155] PSegDisorderA×PSegDisorderDisA Formula 1

[0156] Among them, FAC AOI Represents the information age performance indicator. α represents the preset weight of the congestion index, β represents the preset weight of the segmentation index, and ɡ represents the preset weight of the disorder index.

[0157] It should be noted that the specific sizes of α, β, and ɡ can be determined as needed. For example, they can be 0.4, 0.3, and 0.3, respectively. For another example, they can be 0.3, 0.4, 0.3, etc.

[0158] It is understandable that since the congestion index reflects the impact of the difference in the interval time between the ingress and egress packets, this change directly affects the timeliness of information, thereby affecting the age of information. The segmentation index takes into account the number of times a data packet is segmented and the distance of the segments during transmission. More segments and longer segmentation distances may increase transmission delays, thereby increasing the age of information. The disorder index takes into account the number of times and the distance of disorder in which data packets are disordered during transmission. Disordered data packets will cause the receiving end to need to reorder, thereby increasing processing time and also affecting the age of information. In this way, by comprehensively considering the congestion index, segmentation index, and disorder index, the impact of the wireless network transmission process on the age of information can be more comprehensively measured.

[0159] In a possible embodiment, the information age performance indicator determination method in the present application may also include the following S501.

[0160] S501: When the information age performance indicator is greater than or equal to a first threshold, adjust the service corresponding to the data packet.

[0161] The first threshold value can be set as required, for example, 1.

[0162] As a possible implementation manner, the information age performance indicator determination device can adjust the target service corresponding to the data packet according to the target strategy.

[0163] It should be noted that the target strategy includes at least one of the following:

[0164] The priority of the target service is adjusted from the first priority to the second priority; the second priority is greater than the first priority.

[0165] The transmission resource quantity of 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.

[0166] The signal to interference plus noise ratio SINR value 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.

[0167] The network used by the target service is adjusted from the first network to the second network; the information age performance index of the second network is smaller than the information age performance index of the first network.

[0168] In one example, the execution logic of the target policy may include the following 1-6:

[0169] 1. The information age performance index determination device can determine whether the congestion index is greater than the second threshold, whether the segmentation index is greater than the third threshold, and whether the disorder index is greater than the fourth threshold when the information age performance index is greater than or equal to the first threshold.

[0170] The second threshold, the third threshold and the fourth threshold can be set as needed, for example, 1, 1.1, 1.2, etc.

[0171] 2. When it is determined that the congestion index is greater than the second threshold, the segmentation index is less than or equal to the third threshold, and the disorder index is less than or equal to the fourth threshold, the priority of the target service is adjusted from the first priority to the second priority.

[0172] 3. When it is determined that the congestion index is greater than the second threshold, the segmentation index is greater than the third threshold, and the disorder index is less than or equal to the fourth threshold, the priority of the target service is adjusted from the first priority to the second priority, and the number of transmission resources of the target service is adjusted from the first resource number to the second resource number.

[0173] In one example, the second resource quantity may be A*fun(KPI).

[0174] Wherein, A represents the first resource quantity. fun(KPI) represents the amplification factor. It can be determined according to the preset threshold of the information age performance indicator. The amplification factor can be 1, 1.2, 1.3, ... 2, etc.

[0175] For example, when the preset threshold of the information age performance indicator is 1-1.1, the corresponding amplification factor may be 1. When the preset threshold of the information age performance indicator is 1.1-1.2, the corresponding amplification factor may be 1.2. When the preset threshold of the information age performance indicator is 1.2-1.3, the corresponding amplification factor may be 1.3.

[0176] 4. When it is determined that the congestion index is greater than the second threshold, the segmentation index is less than or equal to the third threshold, and the disorder index is greater than the fourth threshold, the priority of the target service is adjusted from the first priority to the second priority, and the signal to interference plus noise ratio SINR value of the target service is adjusted from the first SINR value to the second SINR value.

[0177] For example, the second SINR value may be SINR B*fun(KPI). SINR B represents the first SINR value. fun(KPI) is to find a reduction factor, for example, the reduction factor may be 0.8, 0.7, ..., 0.5, etc.

[0178] For example, when the preset threshold of the information age performance indicator is 1-1.1, the corresponding reduction coefficient may be 0.8. When the preset threshold of the information age performance indicator is 1.1-1.2, the corresponding reduction coefficient may be 0.7. When the preset threshold of the information age performance indicator is 1.2-1.3, the corresponding reduction coefficient may be 0.5.

[0179] 5. When it is determined that the congestion index is greater than the second threshold, the segmentation index is greater than the third threshold, and the disorder index is greater than the fourth threshold, the priority of the target service is adjusted from the first priority to the second priority, the number of transmission resources of the target service is adjusted from the first resource number to the second resource number, and the signal to interference plus noise ratio SINR value of the target service is adjusted from the first SINR value to the second SINR value.

[0180] 6. When it is determined that the information age performance indicator is still greater than or equal to the first threshold within the preset time period after the adjustment, the target service is migrated from the first network to the second network.

[0181] The information age performance index of the second network is smaller than the information age performance index of the first network.

[0182] In one example, the information age performance indicator determination device can initiate compliance balancing to migrate the target service from the first network to the second network.
