During wireless network transmission (which can also be referred to as air interface transmission), if the influence of the wireless network on the information age of the data packet is large, the wireless network transmission process can be optimized.

[0003] However, since the network device cannot know whether there is an update of the data packet during wireless network transmission, i.e., cannot determine the information age of the data packet in the wireless network transmission, the network device cannot determine the influence of the wireless network on the information age of the data packet.

[0041] In order for those skilled 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 described clearly and completely below in conjunction with the 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 do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, 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. Rather, they are merely examples of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the appended claims.

[0043] It should also be understood that the term "comprising" indicates the presence of the 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 terms used in the present application are explained as follows:

[0045] Latency: Latency refers to the time delay experienced by data from the sending end to the receiving end. In a mobile communication system, latency includes propagation delay (time required from sending to receiving), processing delay (time required for data processing in a mobile communication system), and queuing delay (time spent in the network node queue waiting for transmission in a mobile communication system), etc. Low latency can reduce the length of data transmission, helping to improve the real-time performance of communication.

[0046] Jitter: Jitter refers to the instability or fluctuation of data transmission latency. In a mobile communication system, jitter affects the arrival time interval of data, which can cause instability and delay of real-time applications. Smaller jitter helps maintain the stability and consistency of communication.

[0047] Information age: used to represent the freshness of information. It can also reflect the timeliness of information state update. This is a new field of network research. When the update speed of information state is fast, it does not mean that the utilization rate of the system for sending the updated information state is the maximum utilization rate, nor does it mean that the latency of the system for receiving the updated information state is the minimum latency.

[0048] In an example, the information age of a data packet with a timestamp u at time t is t-u. When the current time is t and the information age is zero, the current data packet is considered fresh. The information age is a stochastic process. For example, Δ(t) = t-u(t).

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

[0050] The information age is used to represent the freshness of information. During wireless network transmission, if the wireless network has a greater impact on the information age of the data packet, 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, cannot determine the information age of the data packet in the wireless network transmission, the network device cannot determine the impact of the wireless network on the information age of the data packet.

[0052] In view of this, the embodiments of the present application provide an information age performance index determination method, which comprises: acquiring the transmission and reception time and the segment number of the data packet in the current wireless network transmission period; determining the information age performance index of the wireless network according to the transmission and reception time and the segment number; and the information age performance index is used to indicate the impact of the wireless network on the information age of the data packet.

[0073] In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, the same items or similar items with basically the same functions and effects are distinguished by using “first”, “second”, etc. The skilled in the art can understand that the “first”, “second”, etc. do not limit the quantity and execution order, and the “first”, “second”, etc. also do not necessarily mean different.

Any embodiment or design solution described herein as "exemplary" or "for example" should not be construed as being more advantageous or superior in any way over other embodiments or design solutions.

For example, at least one of a, b, or c can represent a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

[0076] The following describes the information age performance index determination system in conjunction with Figure 1 The information age performance index determination method provided by the embodiments of the present application is described.

[0077] Figure 3 The flowchart of the information age performance index determination method provided by the embodiments of the present application is shown in Figure 3 The method includes the following S301-S302:

[0078] S301, acquiring the transmission and reception time of the data packet in the current wireless network transmission period and the segment number.

[0079] The length of the wireless network transmission period can be set as needed. For example, it can be 1s. 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 after the first data packet is segmented. The segment number is used to represent the preset order of sending the data packet. The smaller the segment number is, the earlier the preset order of sending the data packet is.

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

[0081] As a further possible implementation, the information age performance index determination apparatus can record the identity of the data packet and the corresponding receiving time in the case of receiving the data packet at the wireless network entry, and record the identity of the data packet and the corresponding sending time in the case of sending the data packet at the wireless network exit, to obtain the sending and receiving time of the data packet in the current wireless network transmission period. Further, the data packet is parsed at the wireless network exit to obtain the segment 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 an example, the target PLMN ID can be 46001, etc. The target QOS level can be the target 5G QoS Identifier (5QI) level, the target QoS class identifier (QCI) level, etc.

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

[0085] Figure 4 A schematic diagram showing a data packet transmission process is shown. As shown in Figure 4 , the terminal device and the network device can include a simple dfs access 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).

[0086] In the process of sending the data packet from the terminal device to the network device, the wireless network entry 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] In the process that the network device sends the data packet to the terminal device, the wireless network entry is the B point, the B point is connected with the core network. The receiving time of the data packet is the time when the data packet arrives at the B point, the sending time of the data packet is the time when the data packet arrives at the D point, and the segment serial number is the segment serial number of the data packet at the D point.

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

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

[0090] In practical applications, the applicable traffic type corresponding to the data packet is packet switching traffic.

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

[0092] S302, according to the receiving and sending time and the segment serial number, determine the information age performance index of the wireless network.

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

[0094] As a possible implementation manner, the information age performance index determination apparatus can determine the information age performance index of the wireless network according to the receiving and sending time and the segment serial number in the case that the number of data packets in the current wireless network transmission period is greater than the number threshold.

[0095] The number threshold can be set as needed. For example, it can be 20, 50, 100, etc.

[0096] It can be understood that in the case that the number of data packets in the current wireless network transmission period is greater than the number threshold, the information age performance index of the wireless network is determined, which can avoid too few data packets in the wireless network transmission period and ensure the reliability of the information age performance index of the wireless network.

[0097] As another possible implementation manner, the information age performance index determination apparatus can determine the information age performance index of the wireless network according to the receiving and sending time and the segment serial number in the case that the number of data packets in the current wireless network transmission period is any number.

[0098] Based on the technical solutions provided in the present application, the information age performance index of the wireless network is determined by the receiving and transmitting time and the segment serial number of the data packet in the wireless network transmission period. The information age performance index is used to indicate the influence degree of the wireless network on the information age of the data packet. Since the receiving and transmitting time of the data packet can reflect the inflow and outflow state of the data packet in the wireless network transmission process, and the segment serial number can reflect the segment state of the data packet in the wireless network transmission process. The inflow and outflow state and the segment state 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 The flowchart of another information age performance index determination method provided in the embodiments of the present application is shown in FIG. 6. As shown in FIG. 6, in order to determine the information age performance index of the wireless network, S302 in the information age performance index determination method of the present application can include the following S401-S402. Figure 5

[0100] S401, determine the congestion index, the segment index and the out-of-order index of the data packet.

[0101] The congestion index is used to indicate the congestion state of the wireless network transmission; the segment index is used to indicate the degree of segmentation of the data packet; and the out-of-order index is used to indicate the disorder degree of the sending order of the data packet.

[0102] The processes of determining the congestion index, the segment index and the out-of-order index are introduced below respectively.

[0103] 1. Congestion index

[0104] S1, determine the exit interval time and the entry interval time.

[0105] The entry interval time is the interval time between the first data packets received continuously; and the exit interval time is the interval time between the second data packets transmitted continuously.

The QOS level of the second data packet is the target QOS level, the PLMN ID is the target PLMN ID, and the single network slice selection assistance information (S-NSSAI) is the target S-NSSAI.

[0107] ​As a possible implementation manner, the information age performance index determination apparatus can take the average of interval times between all continuously received first data packets as the entry interval time, and take the average of interval times between continuously sent second data packets as the exit interval time.

[0108] The average of interval times between all continuously received first data packets is calculated in the following manner: the sum of time intervals (i.e. the arrival time of a later data packet minus the arrival time of a previous data packet) at which all data packets arrive at the system entry, divided by the total number of data packets minus one.

[0109] The average of interval times between all continuously sent second data packets is calculated in the following manner: the sum of time intervals (i.e. the arrival time of a later data packet minus the arrival time of a previous data packet) at which all data packets arrive at the system exit, divided by the total number of data packets minus one.

[0110] In actual application, the units of the exit interval time and the entry interval time can be milliseconds.

[0111] The format of the measurement name of the entry interval time can be SystemEntry.PacketIntervalAvg_Filter. Filter represents the 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] In combination Figure 4 In the process in which the terminal device sends data packets to the network device, the wireless network entry is point A and the wireless network exit is point C. The first data packet is the data packet of point A, and the second data packet is the data packet of point C. In the process in which the network device sends data packets to the terminal device, the wireless network entry is point B and the wireless network exit is point D. The first data packet is the data packet of point B, and the second data packet is the data packet of point D.

[0114] In some embodiments, the use of measuring the entry interval time and the exit interval time is to guarantee performance (user plane connection quality) in the integrity area, and to evaluate the congestion degree of the network and the effectiveness of the traffic scheduling strategy.

[0115] S2, determine the congestion index according to the difference between the exit interval time and the entry interval time.

[0116] In an example, the information age performance index determination apparatus can determine the difference between the exit interval time and the entry interval time as the congestion index.

[0117] For example, the congestion index can be .

[0118] wherein, represents the exit interval time (may also be denoted as Exit.PacketIntervalAvg). represents the entry interval time (may also be denoted as Entry.PacketIntervalAvg).

[0119] In another example, the information age performance indicator determination apparatus can determine the square of the difference between the exit interval time and the entry interval time as the congestion index.

[0120] For example, the congestion index can be .

[0121] 2. Segmentation index

[0122] S11, determine the segmentation distance of the second data packet and the segmentation times of the first data packet.

[0123] wherein, the segmentation distance is the transmission time difference between the second data packets with adjacent serial numbers.

[0124] As a possible implementation, the information age performance indicator determination apparatus can take the average of the transmission time differences between all second data packets with adjacent serial numbers as the segmentation distance of the second data packet, and take the average of the segmentation times of all first data packets as the exit interval time.

[0125] wherein, the average of the transmission time differences between all second data packets with adjacent serial numbers is calculated in the following manner: the sum of the transmission time differences between all second data packets with adjacent serial numbers is divided by the total segmentation times.

[0126] The average of the segmentation times of all first data packets is calculated in the following manner: the sum of the segmentation times of all first data packets is divided by the total number of first data packets.

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

[0128] The format of the measurement name of the segmentation times of the first data packet can be: PacketSegmentationAvg_Filter. Filter represents the combination of PLMN ID, QoS level and S-NSSAI.

[0129] In combination with Figure 4In the process of sending the data packet by the terminal device to the network device, the wireless network entry is point A and the wireless network exit is point C. The second data packet is the data packet of point C, and the segmentation times of the first data packet are determined according to the segmentation number of the data packet of point C. In the process of sending the data packet by the network device to the terminal device, the wireless network entry is point B and the wireless network exit is point D. The second data packet is the data packet of point D, and the segmentation times of the first data packet are determined according to the segmentation number of the data packet of point D.

[0130] In some embodiments, the use of the segmentation distance of the second data packet and the segmentation times of the first data packet is to evaluate the performance and quality of the network. Higher average segmentation times and larger segmentation distances may indicate network congestion or other problems, which need to be further analyzed and optimized.

[0131] S12, determine the segmentation index according to the product of the segmentation distance of the second data packet and the segmentation times of the first data packet.

[0132] As a possible implementation, the information age performance index determination apparatus can determine the product of the segmentation distance of the second data packet and the segmentation times of the first data packet as the segmentation index.

[0133] For example, the segmentation index can be PSegA x PSegDisA.

[0134] Wherein, PSegA represents the segmentation times of the first data packet. PSegDisA represents the segmentation distance of the second data packet.

[0135] 3, out-of-order index

[0136] S21, determine the proportion of out-of-order data packets and the out-of-order distance.

[0137] Wherein, the out-of-order data packet is a data packet with abnormal sending order. The out-of-order distance is the sequence number difference between the sending time of adjacent second data packets.

[0138] As a possible implementation, the information age performance index determination apparatus can take the number of all out-of-order data packets as the proportion of out-of-order data packets, and take the average of the out-of-order distances of all data packets as the out-of-order distance.

[0139] Wherein, the calculation method of the average of the out-of-order distances of all data packets is to divide the sum of the average of the out-of-order distances of all data packets by the total number of data packets.

[0140] It should be noted that for each second data packet sent, if the sequence number of the second data packet is less 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-order data packet.

[0141] The format of the measurement name of the proportion of out-of-order packets can be PacketDisorderAvg_Filter. Filter represents the combination of PLMN ID, QoS level and S-NSSAI.

[0142] The format of the measurement name of the out-of-order distance is PacketDisorderAvgDistance_Filter. Filter represents the combination of PLMN ID, QoS level and S-NSSAI.

[0143] In combination Figure 4 In the process of sending data packets by the terminal device to the network device, the wireless network entry is point A and the wireless network exit is point C. The second data packet is the data packet of point C. The proportion of out-of-order packets is the proportion of out-of-order packets of point C (or the proportion of out-of-order packets of point D can be counted). The out-of-order distance is determined according to the data packet of point C (or the data packet of point D can be counted). In the process of sending data packets by the network device to the terminal device, the wireless network entry is point B and the wireless network exit is point D. The second data packet is the data packet of point D. The proportion of out-of-order packets is the proportion of out-of-order packets of point D (or the proportion of out-of-order packets of point C can be counted). The out-of-order distance is determined according to the data packet of point D (or the data packet of point C can be counted).

[0144] In some embodiments, the proportion of out-of-order packets and the out-of-order distance are used to evaluate the performance and quality of the network. The proportion of out-of-order packets and the out-of-order distance reflect the stability of the order of data packets arriving in wireless network transmission, which can help identify network congestion or other problems.

[0145] S22, determine the out-of-order index according to the product of the proportion of out-of-order packets and the out-of-order distance.

[0146] As a possible implementation, the information age performance index determination apparatus can determine the product of the proportion of out-of-order packets and the out-of-order distance as the out-of-order index.

[0147] For example, the out-of-order index can be PSegDisorderA x PSegDisorderDisA.

[0148] Wherein, PSegDisorderA represents the proportion of out-of-order packets. PSegDisorderDisA represents the out-of-order distance.

[0149] S402, determine the information age performance index according to the congestion index, the segmentation index and the out-of-order index.

[0150] As a possible implementation manner, the information age performance index determination apparatus can determine the sum of the congestion index, the segmentation index and the disorder index as the information age performance index.

[0151] As another possible implementation manner, the information age performance index determination apparatus can perform weighted processing on the congestion index, the segmentation index and the disorder index based on preset weights, and determine the result of the weighted processing as the information age performance index.

[0152] For example, the information age performance index can be represented by Formula One as follows:

[0153] FAC AOI = + β × PSegA ×PSegDisA +ɡ ×PSegDisorderA ×PSegDisorderDisA Formula One

[0154] Wherein, FAC AOI represents the information age performance index. β represents the preset weight of the congestion index, β represents the preset weight of the segmentation index, and g represents the preset weight of the disorder index.

[0155] It should be noted that the specific sizes of a, β and g can be set as needed, for example, can be 0.4, 0.3 and 0.3 respectively, and for another example, can be 0.3, 0.4 and 0.3 respectively.

[0156] As can be understood, since the congestion index reflects the influence of the difference between the interval time of the entrance and the exit packet, such change directly affects the timeliness of the information, thereby affecting the information age. The segmentation index considers the number of times of segmentation and the distance of segmentation of the data packet in the transmission process. More segmentation and farther segmentation distance can increase the transmission delay, thereby increasing the information age. The disorder index considers the number of times of disorder and the distance of disorder of the data packet in the transmission process. Data packet disorder will cause the receiving end to reorder, thereby increasing the processing time, and also affecting the information age. In this way, by comprehensively considering the congestion index, the segmentation index and the disorder index, the influence of the wireless network transmission process on the information age can be comprehensively measured.

[0157] In a possible embodiment, the information age performance index determination method in the present application can further include the following S501.

[0158] S501, in the case that the information age performance index is greater than or equal to a first threshold, adjusting the service corresponding to the data packet.

[0159] Wherein, the first threshold can be set as needed. For example, it can be 1.

[0160] As a possible implementation manner, the information age performance index determination apparatus can adjust the target service corresponding to the data packet according to a target strategy.

[0161] It should be noted that the target strategy includes at least one of the following:

[0162] adjusting the priority of the target service from a first priority to a second priority; the second priority is greater than the first priority.

[0163] adjusting the number of transmission resources of the target service from a first resource number to a second resource number; the second resource number is greater than the first resource number.

[0164] adjusting the signal to interference plus noise ratio (SINR) value of the target service from a first SINR value to a second SINR value; the second SINR value is less than the first SINR value.

[0165] adjusting the network used by the target service from a first network to a second network; the information age performance index of the second network is less than that of the first network.

[0166] In an example, the execution logic of the target strategy can include the following 1-6:

[0167] 1. The information age performance index determination apparatus can determine whether the congestion index is greater than a second threshold, whether the fragmentation index is greater than a third threshold, and whether the out-of-order index is greater than a fourth threshold when the information age performance index is greater than or equal to a first threshold.

[0168] The second threshold, the third threshold, and the fourth threshold can be set as needed. For example, they can be 1, 1.1, 1.2, etc.

[0169] 2. In a case where the congestion index is greater than the second threshold, the fragmentation index is less than or equal to the third threshold, and the out-of-order index is less than or equal to the fourth threshold, the priority of the target service is adjusted from a first priority to a second priority.

[0170] 3. In a case where the congestion index is greater than the second threshold, the fragmentation index is greater than the third threshold, and the out-of-order index is less than or equal to the fourth threshold, the priority of the target service is adjusted from a first priority to a second priority, and the number of transmission resources of the target service is adjusted from a first resource number to a second resource number.

[0171] In an example, the second resource number can be A*fun(KPI).

[0172] Wherein, A represents the first resource quantity. fun(KPI) represents an amplification factor. The amplification factor can be determined according to a preset threshold at which the information age performance indicator is located. The amplification factor can be 1, 1.2, 1.3,... 2, etc.

[0173] For example, in the case that the preset threshold at which the information age performance indicator is located is 1-1.1, the corresponding amplification factor can be 1. In the case that the preset threshold at which the information age performance indicator is located is 1.1-1.2, the corresponding amplification factor can be 1.2. In the case that the preset threshold at which the information age performance indicator is located is 1.2-1.3, the corresponding amplification factor can be 1.3.

[0174] 4、In the case that the congestion index is greater than the second threshold, the fragmentation index is less than or equal to the third threshold, and the out-of-order 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.

[0175] For example, the second SINR value can be SINR B*fun(KPI). SINR B represents the first SINR value. fun(KPI) is to obtain a reduction factor, such as a reduction factor can be 0.8, 0.7,... 0.5, etc.

[0176] For example, in the case that the preset threshold at which the information age performance indicator is located is 1-1.1, the corresponding reduction factor can be 0.8. In the case that the preset threshold at which the information age performance indicator is located is 1.1-1.2, the corresponding reduction factor can be 0.7. In the case that the preset threshold at which the information age performance indicator is located is 1.2-1.3, the corresponding reduction factor can be 0.5.

[0177] 5、In the case that the congestion index is greater than the second threshold, the fragmentation index is greater than the third threshold, and the out-of-order index is greater than the fourth threshold, the priority of the target service is adjusted from the first priority to the second priority, the quantity of transmission resources of the target service is adjusted from the first resource quantity to the second resource quantity, 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.

[0178] 6、In the case that the information age performance indicator is still greater than or equal to the first threshold within the preset time period after the above adjustment, the target service is migrated from the first network to the second network.

[0179] Wherein, the information age performance indicator of the second network is less than the information age performance indicator of the first network.

[0180] In an example, the information age performance index determination apparatus can initiate a migration of the target service from the first network to the second network in accordance with the balancing.
