[0129] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0130] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0131] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0132] The embodiments of the present application provide an information processing method and device to ensure system performance.

[0133] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0134] See also Figure 1 , Figure 1 is a flowchart of an information processing method provided in an embodiment of the present application, which is applied to a sending node, such as Figure 1 As shown, the following steps are included:

[0135] Step 101: Send a downlink user data PDU in a first measurement window, and when sending the last downlink user data PDU of the first measurement window, carry first measurement indication information in the last downlink user data PDU.

[0136] The first measurement window can be determined in the following manner:

[0137] The sending node sends a downlink user data (DL USER DATA) PDU (or simply referred to as data PDU) according to the initial measurement window, wherein the downlink user data PDU carries the second measurement indication information. The initial measurement window may be, for example, a preset measurement window. Afterwards, the sending node may receive a downlink data delivery status (DLDATA DELIVERY STATUS, DDDS) PDU or an assistance measurement data (ASSISTANCE MEASUREMENT DATA) PDU, wherein the downlink data delivery status PDU or the assistance measurement data PDU includes a desired buffer size for the data radio bearer (Desired buffer size for the data radio bearer) information element and / or a desired data rate (Desired Data Rate) information element, and the desired buffer size information element and / or the desired data rate information element of the data radio bearer are determined according to the second measurement indication information. Afterwards, the sending node determines the first measurement window according to the desired buffer size information element and / or the desired data rate information element of the data radio bearer.

[0138] The size of the first measurement window is less than or equal to the desired buffer size of the data radio bearer indicated by the desired buffer size information element of the data radio bearer. Alternatively, the size of the first measurement window is less than or equal to the number of PDUs identified by the NR-U sequence number (Sequence Number, SN) of the above-mentioned desired buffer size for the data radio bearer.

[0139] The second measurement indication information is carried in the following manner:

[0140] Auxiliary measurement identification information element of downlink user data PDU; or, auxiliary measurement report information element of downlink user data PDU.

[0141] In the embodiment of the present application, different frame formats can be used in the access network user plane (UP) interface protocol to achieve interface throughput measurement. Specifically, the measurement indication information can be reported or carried by extending the existing PDU or adding a new PDU type.

[0142] Among them, the contents of DL USER DATA are shown in Table 1:

[0143] Table 1

[0144]

[0145] In Table 1, the newly added IE in DL USER DATA is Assistance Meas.Flag (Assistance Measurement Identifier). In Table 1, for example, if Report polling = 1, the receiving node needs to feedback DDDS; if Report polling = 0, the receiving node does not need to feedback DDDS (as shown in Table 3); if Assistance Meas.Flag = 1, the fed-back DDDS needs to carry the newly added IE in Table 3 (Highest Transmitted NR-U SN Ind (the highest NR-U sequence number indication sent successfully) and Highest transmitted NR-U Sequence Number (the highest NR-U sequence number sent successfully)) and Highest Transmitted NR-U SN Ind = 1, indicating that the carried Highest transmitted NR-USequence Number is not 0; if Assistance Meas.Flag = 0, Highest Transmitted NR-U SNInd = 0, indicating that the Highest transmitted NR-U Sequence Number is not carried.

[0146] Among them, the content of DL USER DATA can also be shown in Table 2:

[0147] Table 2

[0148]

[0149] In Table 2, the newly added IE in DL USER DATA is Assistance Meas.Report. In Table 2, for example, if Assistance Meas.Report is set to a preset value (such as 1), it means that the receiving node needs to feedback ASSISTANCE MEASUREMENT DATA (as shown in Table 4), and the type of the PDU is 3; if Assistance Meas.Report is 0, no feedback is required.

[0150] Among them, the DDDS part is shown in Table 3:

[0151] Table 3

[0152]

[0153] The newly added IEs in DDDS are: Highest Transmitted NR-U SN Ind (the highest NR-U sequence number indication successfully sent) and Highest transmitted NR-U Sequence Number (the highest NR-U sequence number successfully sent).

[0154] In Table 3, for example, if the Highest Transmitted NR-U SN Ind is a preset value (for example, 1), it indicates that the Highest transmitted NR-U Sequence Number is carried; if it is other values, it indicates that the Highest transmitted NR-U Sequence Number is not carried.

[0155] Among them, in the embodiment of the present application, the newly added type of PDU is:

[0156] ASSISTANCE MEASUREMENT DATA (Assisted Measurement Data), the type of this PDU is 3. Its content is shown in Table 4:

[0157] Table 4

[0158]

[0159] Among them, Desired buffer size for the drb Ind is used to indicate whether to carry "Desired buffer size for the data radio bearer"; Data rate Ind. is used to indicate whether to carry "Desired Data Rate"; Highest transmitted NR-U Sequence Number is used to indicate the highest NR-U sequence number sent successfully.

[0160] The first measurement indication information is carried in the following manner:

[0161] Auxiliary measurement identification information element of downlink user data PDU; or, auxiliary measurement report information element of downlink user data PDU.

[0162] For example, the sending time of the first downlink user data PDU in the first measurement window W is t1. When the last downlink user data PDU in W is sent, the trigger measurement is configured, that is, Assistance Meas.Flag or Assistance Meas.Report is set to 1.

[0163] Step 102: Receive feedback information on the last downlink user data PDU, and determine a first network throughput in the first measurement window according to the feedback information, wherein the feedback information is determined according to the first measurement indication information.

[0164] Here, the sending time t1 of the first downlink user data PDU in the first measurement window and the receiving time t2 of receiving feedback information for the last downlink user data PDU are obtained. The length L of the downlink user data PDU in the first measurement window is obtained. The first network throughput Thr is determined according to the sending time, the receiving time and the length. Wherein, Thr=L / (t2-t1). At the same time, the sending node may move the first measurement window so that the last downlink user data PDU of the first measurement window is used as the first downlink user data PDU of the first measurement window to prepare for subsequent transmission.

[0165] Step 103: Adjust the first measurement window according to the first network throughput.

[0166] In this step, the sending node may obtain a throughput change value according to the first network throughput and the expected throughput value, and adjust the first measurement window according to the throughput change value to obtain an adjusted measurement window.

[0167] The throughput expectation value may be the maximum value of the network throughput obtained in the measurement. Throughput variation value Diff = P-Thr, where P represents the throughput expectation value. For the first adjustment, the throughput expectation value is 0.

[0168] If the throughput change value is less than a first preset value, increase the first measurement window (for example, W=W+n, n is a positive integer) to obtain an adjusted measurement window; if the throughput change value is greater than a second preset value, reduce the first measurement window (for example, W=W / 2) to obtain an adjusted measurement window; wherein the first preset value is less than the second preset value and can be set as needed.

[0169] In this step, the sending node may also compare the size of the first measurement window with the expected buffer size of the data radio bearer to obtain a comparison result, wherein the expected buffer size of the data radio bearer is indicated by the expected buffer size information element of the data radio bearer of the downlink data delivery status PDU or the auxiliary measurement data PDU. The first measurement window is adjusted according to the comparison result to obtain a second measurement window, and a throughput change value is obtained according to the first network throughput and the expected throughput value. Then, the second measurement window is adjusted according to the throughput change value to obtain an adjusted measurement window.

[0170] In the above process of obtaining the second measurement window, if the size of the first measurement window is less than or equal to the expected cache size of the data radio bearer, the size of the second measurement window is the size of the first measurement window; if the size of the first measurement window is greater than the expected cache size of the data radio bearer, the size of the second measurement window is the expected cache size of the data radio bearer.

[0171] In the process of adjusting the second measurement window according to the throughput change value to obtain the adjusted measurement window, if the throughput change value is less than a first preset value, the second measurement window is increased to obtain the adjusted measurement window; if the throughput change value is greater than a second preset value, the second measurement window is reduced to obtain the adjusted measurement window; wherein the first preset value is less than the second preset value and can be set as needed.

[0172] Through the above method, the processing conditions of the sending node and the receiving node can be comprehensively considered, which is convenient for improving the system performance.

[0173] In an embodiment of the present application, the sending node can adjust the measurement window according to the feedback information, thereby adjusting the data scheduling of the interface, and avoiding the impact on system performance due to the inability to obtain the latest information reported by the receiving node in a timely manner.

[0174] Optionally, the sending node may also adjust the transmission rate of the sending node according to the adjusted measurement window, the first network throughput and the throughput change value.

[0175] Specifically, if the throughput change value is less than or equal to a first preset value, the transmission rate is increased; or, if the throughput change value is greater than or equal to a second preset value and the adjusted measurement window is smaller than the data in the target sending cache, the transmission rate is reduced; or, if the throughput change value is greater than or equal to the second preset value and the first network throughput is less than the target sending rate, the transmission rate is reduced.

[0176] The data of the target sending buffer can be determined according to the expected buffer size of the data radio bearer, and the target sending rate can be set as required.

[0177] See also Figure 2 , Figure 2 is a flowchart of an information processing method provided in an embodiment of the present application, which is applied to a receiving node, such as Figure 2 As shown, the following steps are included:

[0178] Step 201: receiving a downlink user data PDU sent in a first measurement window, wherein the last downlink user data PDU in the first measurement window carries first measurement indication information;

[0179] Step 202: Send feedback information on the last downlink user data PDU according to the first measurement indication information.

[0180] The first measurement indication information is carried in the following manner:

[0181] The auxiliary measurement identification information element of the last downlink user data PDU; or the auxiliary measurement report information element of the last downlink user data PDU.

[0182] According to different carrying modes of the first measurement indication information, the receiving node may have different processing modes.

[0183] If the first measurement indication information is carried in an auxiliary measurement identification information element, a downlink data transfer status PDU is sent; or if the first measurement indication information is carried in an auxiliary measurement report information element, an auxiliary measurement data PDU is sent;

[0184] The feedback information is carried in the downlink data transfer status PDU or the auxiliary measurement data PDU.

[0185] In an embodiment of the present application, the sending node can adjust the measurement window according to the feedback information, thereby adjusting the data scheduling of the interface, and avoiding the impact on system performance due to the inability to obtain the latest information reported by the receiving node in a timely manner.

[0186] In an embodiment of the present application, real-time perception of network transmission throughput is introduced into the user plane logical interface protocol of the access network, and the transmission cells or new PDU types are added based on the existing user plane PDU transmission. The network element configuration periodically measures the throughput within the window according to the measurement window, and then adaptively adjusts the measurement window according to the changes in the throughput, and assists the sender's scheduling strategy to adjust the transmission rate or path, so that the sending node can monitor the changes in network transmission in time when the transmission between nodes is slow and make active adjustments, so as to avoid sending more data to the congested link due to waiting or inability to receive the report information of the receiving node.

[0187] In one embodiment of the present application, an extension is performed based on the existing PDU type and measured at the receiving side. Figure 3 and Figure 4 , the process may include:

[0188] Step 301: Network elements A and B transmit data via the NR-UP interface, and A receives a desired buffer size for the data radio bearer (hereinafter referred to as desired buffer size) fed back by B.

[0189] NE A configures measurement, sets window W=3 (including SN 0-2), at which point the expected Diff value is D'=Thrmax=0, and configures the interface transmission number NR-U SN for the data PDU;

[0190] Step 302: Send SN 0 data at time t0, send the last data PDUSN 2 in W at time t1, and set Assistance Meas.Flag=1 and Report polling=1 in DL USER DATA where SN 2 is located;

[0191] Step 303: After receiving the PDU in step 302, network element B generates a DDDS PDU, sets Highest Transmitted NR-U SN Ind = 1 and Highest transmitted NR-U Sequence Number = 2, and sends it to A;

[0192] Step 304: After receiving the above DDDS at time t1', network element A starts calculation, firstly calculating the data PDU length L in W, then calculating the throughput Thr=L / (t1'-t0), and updating Thrmax and D';

[0193] Step 305: Calculate Diff=D'-Thr, and compare Diff with threshold values ​​Thres1 and Thres2 (Thres1<Thres2).

[0194] If diff<Thres1, then increase the window size; if diff>Thres2, then reduce the window size. Assume that, in this embodiment, Thres1<Diff<Thres2, then W does not need to be changed, and is directly moved, and the range becomes to include SN 2-4, and data continues to be sent;

[0195] Afterwards, SN 4 is sent at time t2, and steps 302, 303, and 304 are repeated to obtain Diff. For example, network element A sends SN, records the time t(n+1) when the last data PDU in W is sent, records the time t(n+1)' when the last data PDU ACK is received in W, calculates the length L of the data PDU in W, and calculates Thr=L / t(n+1)'-tn and Diff.

[0196] When Diff>Thres2, it is found that the throughput is significantly reduced, for example, it can be reduced to W=2. Network element A can configure the buffer of data to be sent or the sending rate with reference to the change of W and the change of Desired data rate that may be carried;

[0197] When Diff<Thres1, it is found that the throughput is ideal, for example, W=4 can be increased, and network element A can configure the buffer of data to be sent or the sending rate with reference to the change of W and the change of Desired data rate that may be carried.

[0198] In one embodiment of the present application, an extension is performed based on the existing PDU type and measured at the receiving side. Figure 5 and Figure 6 , the process may include:

[0199] Step 501: Network elements A and B transmit data via the NR-UP interface, and A receives the desired buffer size fed back by B;

[0200] NE A configures measurement, sets window W=3 (including SN 0-2), at which point the expected Diff value is D'=Thrmax=0, and configures the interface transmission number NR-U SN for the data PDU;

[0201] Step 502: Send SN 0 data at time t0, send the last data PDUSN 2 in W at time t1, and set Assistance Meas.Report=1 in DL USER DATA where SN 2 is located;

[0202] Step 503: After receiving the PDU in step 502, network element B generates an ASSISTANCE MEASUREMENT DATA PDU, sets Highest transmitted NR-U Sequence Number = 2, sets corresponding fields according to the expected data buffer and data rate, and sends it to network element A;

[0203] When network element B expects that the data buffer and data rate will not change, it sets Desired buffer size for the drb Ind = 0, Data Rate Ind = 0, and the corresponding Desired buffer size and Desired data rate do not exist;

[0204] When network element B expects data buffering and / or data rate transmission changes, it sets Desired buffer size for the drb Ind = 1 and / or Data Rate Ind = 1, and fills in the corresponding Desired buffer size and Desired data rate fields;

[0205] Step 504: After receiving the feedback of the last data PDU at time t1', network element A calculates the data PDU length L in W, calculates the throughput Thr=L / (t1'-t0), updates Thrmax and D', and then adjusts W according to the Desired buffersize that may be carried:

[0206] When W≤Desired buffer size, W remains unchanged; when W>Desired buffer size, W is reduced to Desired buffer size;

[0207] Step 505: Calculate Diff=D'-Thr, and compare Diff with threshold values ​​Thres1 and Thres2 (Thres1<Thres2).

[0208] If diff<Thres1, then increase the window size; if diff>Thres2, then reduce the window size. Assume that, in this embodiment, Thres1<Diff<Thres2, then W obtained in step 504 does not need to be changed, and is directly moved to include SN 2-4, and data continues to be sent;

[0209] Step 506: Send SN 4 at time t2, repeat steps 502, 503, and 504 to obtain Diff. For example, network element A sends SN, records the time t(n+1) when the last data PDU in W is sent, records the time t(n+1)' when the last data PDU ACK is received in W, calculates the length L of the data PDU in W, calculates Thr=L / t(n+1)'-tn and Diff.

[0210] When Diff>Thres2, it is found that the throughput is significantly reduced, and W=2 is reduced. Network element A can configure the buffer of data to be sent or the sending rate according to the change of W and the change of Desired data rate that may be carried;

[0211] When Diff<Thres1, it is found that the throughput is ideal, and W=4 is increased. The network element A can configure the buffer of the data to be sent or the sending rate with reference to the change of W and the change of the Desired data rate that may be carried.

[0212] It can be seen from the above that the user-plane traffic perception method of the embodiment of the present application can provide flexible and real-time perception of network transmission with less overhead. When the transmission is good, it can reduce the measurement cycle and reduce the overhead. When the transmission between communication network nodes is limited, the real-time performance of the measurement is improved. The window and throughput information is provided to help the sending node to perceive the network transmission situation in time, thereby actively adjusting the data scheduling of the interface to avoid the impact on system performance due to waiting or loss and the inability to obtain the latest information reported by the receiving node in time.
