For a better understanding of the technical solutions described in any of the embodiments of the present disclosure, first, a partial explanation of the base station measurements is given:

in one embodiment, the packet loss measurement mechanism of the RAN may be packet loss of a set (set) of protocol data units (Protocol Data Unit, PDUs) in the Downlink (DL) of each data radio bearer (Data Radio Bearer, DRB) for each UE. The packet loss of the PDU set in DL of each DRB for each UE may be as shown in table 1.

TABLE 1

That is, the loss rate of the downlink data packet at the air interface can be counted. The statistical downlink data loss rate at the air interface may be DRB based. In some embodiments, packets transmitted on one DRB do not distinguish between different traffic attributes. Here, a packet transmitted on the air but not successfully acknowledged is considered to be lost on the air.

In one embodiment, the packet loss parameter description of the PDU set in DL of each DRB for each UE may be as shown in table 2.

TABLE 2

Namely, M (T, drbid), is the packet loss rate of the PDU set in DL of each DRB for each UE. Dloss (T, drbid), which is the number of data packets that have been transmitted over the air but not successfully acknowledged in time period (T) in each DRB. Here, if the transmission of a data packet is likely to continue in another cell, the data packet is not included in this count. N (T, drbid) is the number of data packets in each DRB that have been transmitted over the air and that have received a successful acknowledgement during the time period (T). T, the time period for which the measurement is made. drbid, DRB measured.

In some embodiments, in Extended Reality (XR) services, the distinction can be made according to the importance of the data; for example, data that can be divided into I frames and P frames; wherein I frames are relatively important frames and P frames are relatively unimportant frames. Here, the UE may decode with the I frame; and P frames cannot be decoded alone.

In one embodiment, a set of PDUs is introduced; the set of PDUs may be made up of a plurality of PDUs. Sometimes if all data in one PDU set need to reach a higher layer to be decoded correctly; and sometimes the data in one PDU set need not reach all higher layers and can be decoded correctly.

In one embodiment, the UPF identifies the PDU set and is placed in the GTP-U layer (layer) and delivers the RAN. The UPF identifies the PDU set for the Downlink (DL) PDU at the GTP-U layer by a GTP-U header extension. GTP-U flag identifying the PDUs belonging to the PDU set and the following information for each PDU set: PDU set Sequence Number (SN) (solutions 7, 8, 9, 11, 12, 14, 19, 20, 21, 22, 23, 50, 53, 55, 56); the start or end PDU of the PDU set (solutions 11, 12, 15, 18, 21, 22, 55, 56); PDU SNs in the PDU set (solutions 11, 20, 22, 55, 56); the number of PDUs within the PDU set (solutions 9, 20, 50) and/or the PDU set size (in bytes).

It can be seen that some basic parameters of the UPF identification PDU set may include at least one of the following: sequence number of PDU set; sequence numbers of the start PDU and the end PDU (i.e. sequence number of the first PDU or the last PDU in PDU set); the PDU set contains the number of PDUs; and the sequence numbers of the PDU and the intermediate PDU.

In one embodiment, on the same DRB, the packets it transmits may be associated with different levels of importance for the sets of packets. And in XR it is possible that one DRB will associate multiple radio link layer control protocol (Radio Link Control, RLC) entities. However, in the current PDCP layer measurement mechanism, measurement according to importance level for a packet set or PLC entity is not involved. New modes of operation need to be considered.

Besides, in XR, there is a way that packets need to be lost on the air interface according to the packet set. If one data packet in the data packet set is not normally transmitted in the air interface, the data packet of the whole data packet set needs to be discarded in the air interface. There is also a need to add new packet loss statistics.

Illustratively, the base station issues a time delay from grant to receipt (Transmission Block, transport block), i.e., an uplink average air interface packet delay for the packet.

In one embodiment, one DRB may comprise at least one logical channel. In some embodiments of the present disclosure, at least one includes one or more; the plurality includes two or more. The data packet set may be associated with a logical information, and the data packet set may be transmitted on the logical channel; alternatively, a portion of the packets in the set of packets may be associated with a logical channel on which the portion of the packets may be transmitted.

Illustratively, the base station receives two types of data packets, the two types of data packets being associated with two logical channels for transmission; the base station may measure the packet loss rate of the data packets in the two logical channels or measure the delay of the data packets in the two logical channels, respectively.

As such, in embodiments of the present disclosure, the measurement of the data packet by the base station may be a measurement for the logical channel, which may provide a measurement of packet loss and/or delay of the data packet with finer granularity.

In some embodiments of the present disclosure, the second type packet loss measurement may be the second type packet loss measurement in the above embodiments.

Illustratively, after receiving the UPF and sending the UPF to the data packet, the base station measures the number of the received data packets; and measuring the number of data packets which are not successfully transmitted at the base station; alternatively, the base station may also determine the ratio of data packets that were not successfully transmitted at the base station based on the ratio of the number of data packets that were not successfully transmitted at the base station to the number of data packets received. Here, the packet may be a GTP-U packet.

In one embodiment, the ratio may be a percentage.

In one embodiment, unsuccessful transmission at a base station includes at least: the PDCP layer discards the data packet. Here, the PDCP layer discards a packet refers to a packet discarded before transmission. Thus, the measurement of the second type packet loss can be realized.

In another embodiment, the data packet that is not successfully transmitted at the base station may further include: and the data packet which is not successfully transmitted on the downlink air interface. Thus, the measurement of the first type packet loss can be realized.

In one embodiment, based on the trigger condition, the determining the measure of the second type of packet loss may be: based on the trigger condition, measurement of packet loss for the data packet set.

Illustratively, the trigger condition is a timer timeout. The base station sets a timer; if at least one of the data packets in the data packet set is not transmitted to the base station before the timer expires, the base station determines to discard the entire data packet set.

Illustratively, the trigger condition is that the data packet is discarded when at least one data packet in the set of data packets is not successfully transmitted. The base station receives the data packet set sent by the UPF, and if one or more data in the data packet set fails to be received, the base station determines to discard the whole data packet set.

Thus, in the embodiment of the present disclosure, the packet loss measurement of the PDCP layer may be determined based on the trigger condition, so that flexible packet loss measurement under different conditions may be implemented, and more application scenarios are adapted.

Of course, in other embodiments, the trigger condition is any manner that may be implemented; for example, the trigger condition may be, but is not limited to: discarding the data packet when the importance level of the data packet is relatively low, discarding the data packet when the service type corresponding to the data packet is a predetermined type, discarding the data packet when the data packet is larger than a predetermined byte, and the like; the triggering conditions are not limited herein.

Of course, in other embodiments, the base station may determine a measure of the first type of packet loss based on the trigger condition; wherein the trigger condition includes at least one of: the timer times out; and discarding the set of data packets when at least one of the set of data packets is not successfully transmitted. Here, the unsuccessful transmission of the data packet means that the data packet is not successfully transmitted on the downlink air interface, i.e., is not transmitted to the other party.

The embodiment of the disclosure provides a base station measurement method, which is executed by a base station and comprises the following steps: determining measurement of packet loss of the data packet based on the importance level of the data packet; and/or determining a measure of packet loss based on the identification of the QoS flow of the packet.

Illustratively, the GTP-U packet header may carry: the importance or importance level of a set of PDUs. The base station may determine that the PDU sets of low importance level are discarded preferentially according to the importance level of the PDU sets.

For example, different data packets may correspond to different QoS flow identifiers, and the base station may discard the data packet corresponding to the predetermined QoS flow identifier.

In the embodiment of the disclosure, the base station may select an appropriate data packet to measure packet loss according to the importance level of the data packet or the identifier of the QoS flow.

Of course, in other embodiments, the base station may also determine the measure of the first type of packet loss based on the importance level of the data packet and/or the identification of the QoS flow.

To further explain any embodiments of the present disclosure, a specific embodiment is provided below.

The present disclosure provides a base station measurement method, which is performed by a base station and includes at least one of the following steps:

step S91: the base station determines the measurement of the data packet; optionally, the base station determines an enhancement mechanism for the statistical measure of packet refinement;

optionally, the base station measures a first type of packet loss measurement. The base station measurement of the first type of packet loss measurement may be measurement of packet loss (Packet Uu Loss Rate in the DL) of the downlink on the air interface.

Optionally, the base station measures a second type of packet loss measurement. The second type of packet loss measurement by the base station may be either a measurement of downlink packet loss (Packet Loss Rate in the DL).

Optionally, the base station measures a first type of delay measurement. The first type of delay measurement by the base station may be a measurement of the downlink air interface delay (DL delay in over-the-air interface) of the measurement packet.

Optionally, the base station measures a second type of delay measurement. The second type of delay measurement by the base station may be a measurement of the uplink Average air interface packet delay (Average over-the-air interface packet delay in the UL).

It will be appreciated that the enhanced mechanism of statistical measures for determining packet refinement by the base station is not limited to the above 4 statistics or measures, but is applicable to newly introduced statistics or measures in the future.

Step S92: the base station determines that the measurement of the data packet is a measurement for a logical channel;

alternatively, when the base station performs measurements (or statistics), it will perform measurements (or statistics) for data packets destined for or associated to a certain logical channel. Illustratively, the base station PDCP layer receives two types of data packets from a higher layer and associates to two logical channels for transmission; and separately measures (or counts) the packets addressed to the two logical channels, respectively. Here, the data packets destined for or associated to a certain logical channel will be determined based on the basic parameters of the PDU set importance (PDU Set importance) carried in the GTP-U header.

Alternatively, as shown in table 3, the base station determines that the first type of packet loss measurement (or statistic) is a measurement (or statistic) for the logical channel.

TABLE 3 Table 3

That is, the loss rate of downstream packets at the air interface may be measured (or counted). The measured (or statistical) loss rate of downstream data over the air may be based on the logical channel.

Alternatively, the packet loss parameter description of the data packet of each UE in each logical channel may be as shown in table 4.

/>

TABLE 4 Table 4

Namely, M (T, lchid), a packet loss rate of data packets in DL of each LCH for each UE; dloss (T, lchid), which is the number of packets that have been transmitted over the air but not successfully acknowledged in each LCH period; n (T, lchid), which is the number of data packets that have been transmitted over the air and that have received a successful acknowledgement in each LCH period; t is the time period in which the measurement is made; lchid, LCH measured. For example, M (T, lchid) may be a packet loss rate of the data packet in the above embodiment within a predetermined time of the associated logical channel; dloss (T, lchid) the first value in the above example; n (T, lchid) may be the second value in the above examples; t is the predetermined time in the above embodiment.

Optionally, when the base station performs statistics, separate statistics are performed for the PDU set importance (PDU Set importance) carried in the GTP-U header.

It will be appreciated that the packet loss rate or number of packets lost for low importance levels may be higher than the packet loss rate or number of packets lost for high importance levels.

Step S93: the base station maintains a first upper limit value for the first type packet loss measurement; the first upper limit value is the upper limit value of the packet loss of the downlink air interface;

optionally, the first upper limit value is PSER; if the core network element does not provide PSER, the base station maintains the second upper limit value, namely the PER. Here, the PSER is a stricter concept that requires one packet, i.e., all packets in the packet, to meet the requirement.

Step S94: and the base station configures the second type of packet loss measurement.

Optionally, after the base station receives an incoming data packet (e.g., a GTP-U data packet) from the UPF, the number and/or ratio of data packets that have not been successfully transmitted at the base station are counted.

Optionally, the unsuccessful transmission at the base station includes: packet loss of the PDCP layer; wherein, packet loss of the PDCP layer includes packet loss for a set of data packets. The triggering condition for packet loss of the PDCP layer may be a discard timer time out or a discard of the entire set of data packets for which the data packet in the set of data packets failed to be delivered.

Optionally, when the base station performs measurement (or statistics), separate measurement (or statistics) is performed for the PDU set importance (PDU Set importance) carried in the GTP-U packet header. Here, packets of low importance level are preferentially discarded when the network is congested. It will be appreciated that the packet loss rate or number of packets lost for low importance levels may be higher than the packet loss rate or number of packets lost for high importance levels.

Illustratively, the measurement provides the number of GTP packets that were not successfully delivered at the base station after transmission by the UPF. The measurement is the rate of loss of incoming GTP packets in the base station, which is divided into sub-counters of importance for each packet set for separate measurements. I.e. This measurement provides the number of GTP data packets which are not successfully delivered at gNB after being sent by upf.it is a measure of the incoming GTP data packet loss in g nb.the measurement is split into subcounters per Packet set importance per QoS level (5 QI).

The specific calculation mode can be calculated by statistics: the number of packets lost among all GTP packets sent by the UPF to the base station. The measurement is divided into sub-counters of importance for each data packet set for separate statistics. Namely This measurement is obtained by a counter: number of missing incoming GTP sequence numbers (TS 29.281) among all GTP packets delivered by a UPF to a gNB. The separate subcounter can be maintained for each Packet set importance per QoS level (5 QI).

Optionally, when the base station performs statistics, statistics is performed according to QoS flows, for example, statistics is performed according to QoS flow identifiers corresponding to the data packets. I.e. separate statistics of data packets from different Qos flows.

In addition, for delay statistics measured by the base station:

optionally, when the base station performs statistics, separate statistics are performed for the PDU set importance (PDU Set importance) carried in the GTP-U header. It will be appreciated that the data delay statistics for low importance levels may be higher than the delay statistics for high importance levels of data packets.

The measurements of the base station in the embodiments to which the present disclosure relates may be achieved by statistics of the base station.
