Description

Layer two statistical method and node equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a layer two statistical method and a node device.

Background

For low-delay and high-reliability services, because of high requirements for delay and reliability, a solution provided by 3GPP at present introduces a duplicate transmission (duplication) mechanism, that is, a Packet Data Convergence Protocol Data Unit (PDCP PDU) transmits the same Packet Data Convergence Protocol Data Unit through multiple paths, improves transmission reliability through multipath transmission gain, and reduces transmission delay.

In the current layer 2 measurement scheme, for different statistics, parameters related to data reporting may need to be acquired from different layers (medium access control MAC/radio link layer control protocol RLC/PDCP/service data adaptation protocol SDAP), and then final statistics is calculated by summarizing. However, for a repeated transmission mechanism used for a low-delay and high-reliability service, on one hand, no statistical parameters are available to quantify the repeated transmission mechanism, which may cause inaccuracy of a statistical result; on the other hand, there is also a need for relevant statistical parameters to evaluate the performance of data transmission using the retransmission method.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings.

In order to enable those skilled in the art to better understand the method of the embodiments of the present invention, the following description is made.

(1) The transmission is repeated.

In the NR Rel-15 stage, two-way retransmission is supported and configured, that is, a PDCP entity corresponding to one radio bearer is mapped to two RLC entities, and Carrier Aggregation (CA) and Dual Connectivity (Dual Connectivity) dualization models are shown in fig. 1 and fig. 2, respectively.

Specifically, a radio bearer (corresponding to a PDCP entity) of the PDCP layer is controlled by at least two logical channels (corresponding to an RLC entity) in the RLC layer.

For the CA model, at least two logic channels corresponding to the radio bearer which is repeatedly transmitted are processed by an MAC entity at an MAC layer, and data from different RLC logic channels are mapped to one or at least two carriers for transmission;

for the DC model, at least two logical channels corresponding to the duplicate RB are respectively mapped to different MAC entities, and data of different RLC logical channels are mapped to different carriers for transmission.

(2) Quality of service QoS infrastructure.

For one UE, the core network may establish one or more PDU sessions (sessions);

one PDU session, which may contain at least two QoS flows (flows), each with its own QoS class, such as a QoS class identifier (QCI/5 QI);

QoS flow from different PDU sessions can be sent to UE by placing same DRB in base station.

(3) Layer two (L2) statistics.

The L2 statistics are statistics of UE or data interaction with UE at the base station side, and may include at least two statistics, which are statistics granularity of per UE, per DRB, per QCI/5 QI.

The statistics measured by L2 may distinguish between upstream and downstream statistics, which may include but are not limited to the following:

total/average number of active (connected) UEs;

total/distributed PRB usage;

averaging packet delays;

average packet drop rate;

average packet loss rate;

total/distributed data throughput;

total/distributed data volume;

each L2 statistic needs to be input by one to more layers of parameter statistics such as MAC/RLC/PDCP/SDAP layers to complete the final statistic calculation.

The statistical method of the L2 statistic will be described below by taking the uplink total PRB usage, downlink data throughput, and uplink packet loss rate as examples.

a. And uplink total PRB usage.

The method is used for counting and reporting the total occupancy rate of Physical Resource Blocks (PRBs) (physical resource blocks) at a base station side (positions of eNB/gNB/gNB-distributed node (DU) and the like), and the counting result can be used for monitoring the network load condition.

The statistical method can be as follows:

the number of used PRBs for uplink data transmission is divided by the total number of all uplink PRBs (available for uplink data transmission) and converted to a percentage.

b. Downlink data throughput.

The method is used for counting the downlink data amount in unit time at the base station side (positions of eNB, gNB, gNB-CU (central node of gNB)/gNB-CU-UP (user plane of the central node of gNB) and the like).

Statistics may be performed for all data packets of all data streams/data bursts (data bursts) within a period of time T, for example, for data bursts that meet a certain data amount/transmission time length requirement.

The statistical method can be as follows:

the sum of the data amount of all packets that meet the requirements (e.g., the reception of an ACK from the UE) is divided by the total length of time it takes to transmit the packets.

The statistics may be per UE, per QCI/5QI, per DRB, or a permutation of the three.

c. And (4) uplink packet loss rate.

And the method is used for counting the unsuccessfully received uplink PDCP packets at the base station side (eNB, gNB, gNB-CU/gNB-CU-UP and the like). Including uplink packet loss rates at all locations within the air interface, at the F1-U interface, and within the base station (eNB, gNB-CU/gNB-CU-UP). Statistics may be performed only for packets that have entered the SDAP/PDCP entity. The statistics may be per UE, per QCI/5QI, per DRB, or a permutation of the three.

Statistics may be performed for data packets within a period of time T, or for all data packets of one data stream/data burst (data burst), for example, statistics may be performed for data burst that meets a certain data amount/transmission time length requirement.

The statistical method can be as follows:

the number of missing uplink PDCP packet sequence numbers divided by the number of all PDCP data packet sequence numbers to obtain a percentage.

As shown in fig. 3, an embodiment of the present invention provides a layer two statistical method, which is applied to a statistical node, where the statistical node may be a statistical node of a network device or a statistical node of a terminal, and the method includes:

step 301: identifying repeat transmission information of a target data transmission in the case that the target data transmission employs a repeat transmission function.

The target data transmission may be transmission of data packets within a preset time period or a preset statistical period, or transmission of a preset number of data packets. Optionally, the preset time period or the preset statistical period may not be continuous in time.

The Data packets counted in the embodiment of the present invention may include Data packets of each layer (MAC/RLC/PDCP/SDAP), and specifically, may be Service Data Units (SDUs) or Protocol Data Units (PDUs) of each layer.

The retransmission information may include a retransmission identification and/or a retransmission layer two statistic.

The retransmission layer two statistic may be obtained by adding a retransmission flag to an existing layer two statistic that is not dedicated to retransmission, or may be a newly introduced statistic for layer two retransmission. For example, the downlink data throughput, the uplink packet loss rate, and the like may be used.

According to the layer two statistical method, under the condition that the target data transmission adopts the repeated transmission function, repeated transmission information of the target data transmission is identified, and the repeated transmission information can be used for related service data of repeated transmission, so that the statistical precision can be improved, and repeated transmission decision of a network side is assisted.

Further, the above-mentioned repeated transmission information for identifying the target data transmission includes:

Optionally, identifying the repeated transmission information of the target data transmission includes:

the first transmission information includes at least one of:

It should be noted that, in the embodiment of the present invention, the DRB with the duplicate transmission function may be all DRBs with the duplicate transmission function in the target data transmission, or may be a DRB that meets a preset statistical condition in all DRBs with the duplicate transmission function in the target data transmission.

In this embodiment of the present invention, the DRBs in the target data transmission may be all DRBs in the target data transmission, or may be DRBs that satisfy a preset statistical condition in all DRBs in the target data transmission.

For example, the ratio information of the sum of the data amounts of the DRBs using the repeat transmission function in the target data transmission to the sum of the data amounts of the DRBs in the target data transmission may be ratio information of the sum of the data amounts of all DRBs using the repeat transmission function in the target data transmission to the sum of the number of all DRBs in the target data transmission, or may be ratio information of the sum of the number of DRBs satisfying a preset statistical condition in all DRBs using the repeat transmission function to the sum of the data amounts of DRBs satisfying the preset statistical condition in all DRBs in the target data transmission. The ratio information of the number of DRBs with the retransmission function in the target data transmission to the number of DRBs in the target data transmission may be ratio information of the number of all DRBs with the retransmission function in the target data transmission to the number of all DRBs in the target data transmission, or may be ratio information of the number of DRBs satisfying a preset statistical condition in all DRBs with the retransmission function to the number of DRBs satisfying the preset statistical condition in all DRBs in the target data transmission.

In the embodiment of the invention, if each DRB starts repeated transmission, the target data transmission with the current statistical granularity of UE/QCI/5QI/DRB is marked as repeated transmission or comprises repeated transmission.

the second transmission information includes at least one of:

and the target data transmission adopts the proportion information of the sum of the data quantity of the data packets with the repeated transmission function and the sum of the data quantity of the data packets in the target data transmission.

In the embodiment of the present invention, the data packet with the retransmission function may be all data packets with the retransmission function in the target data transmission, or may be a data packet that meets a preset statistical condition among all data packets with the retransmission function in the target data transmission.

The data packets in the target data transmission may be all data packets in the target data transmission, or may be data packets that satisfy a preset statistical condition among all data packets in the target data transmission.

The preset statistical condition in the embodiment of the present invention may be that the last data packet of the data burst (data burst) is not counted.

For example, the ratio information of the sum of the data amounts of the packets using the retransmission function in the target data transmission to the sum of the data amounts of the packets in the target data transmission may be ratio information of the sum of the data amounts of all the packets using the retransmission function in the target data transmission to the sum of the number of all the packets in the target data transmission, or ratio information of the sum of the number of the packets satisfying a preset statistical condition among all the packets using the retransmission function to the sum of the data amounts of the packets satisfying the preset statistical condition among all the packets in the target data transmission.

The ratio information of the number of the data packets adopting the retransmission function in the target data transmission to the number of the data packets in the target data transmission may be the ratio information of the number of all the data packets adopting the retransmission function in the target data transmission to the number of all the data packets in the target data transmission, or the ratio information of the number of the data packets satisfying the preset statistical condition in all the data packets adopting the retransmission function to the number of the data packets satisfying the preset statistical condition in all the data packets in the target data transmission.

In the embodiment of the invention, if each PDCP SDU starts repeated transmission, the target data transmission with the current statistic granularity of UE/QCI/5QI/DRB is marked as repeated transmission or comprises repeated transmission.

Further, identifying the retransmission information of the target data transmission by the layer two statistic of the target data transmission comprises:

It should be noted that, in the embodiment of the present invention, the time length for starting the retransmission function may be transmission time of all data packets using the retransmission function in the target data transmission, or may also be transmission time of data packets using the retransmission function and meeting a preset statistical condition in the target data transmission.

The total transmission time of the target data transmission may be the transmission time of all data packets in the target data transmission, or the transmission time of a data packet satisfying a preset statistical condition in all data packets in the target data transmission. For example, the ratio information of the retransmission time is a ratio of transmission time of all data packets using the retransmission function in the target data transmission to transmission time of all data packets in the target data transmission, or a ratio of transmission time of a data packet using the retransmission function and satisfying a preset statistical condition in the target data transmission to transmission time of a data packet satisfying the preset statistical condition in all data packets in the target data transmission.

The following describes an implementation of identifying retransmission information by means of layer two statistics with reference to embodiments one to three.

The first embodiment is as follows:

assume that each DRB starts repeat transmission, and the statistical granularity is DRB, taking statistics of downlink data throughput of each DRB with the statistical period T as an example. The statistic is the downlink data amount in the base station side (eNB, gNB, gNB-CU/gNB-CU-UP and other positions) in a unit time. The statistical method is as follows:

the sum of the data amount of all data packets that meet the requirements (e.g., ACK feedback received from the UE) is divided by the total length of time s taken to transmit these data packets (s is less than or equal to T).

As shown in fig. 4, if 10 data packets are transmitted in the statistical period T, the current statistical downlink data throughput is:

(sum of the number of 1 to 10 ten packets) ÷ total length of time s for transmission of 10 packets;

or when the last data packet of the data burst is not counted into the statistic:

(sum of the number of nine data packets 1 to 3 and 5 to 10) and the total length of time s' for transmitting the 9 data packets.

For repeated transmission duplicate identification, within a statistical period T:

if the time at which the replication starts is a: all data packets in the statistical period T are duplicate transmission, and the statistical data transmission can be identified as duplicate;

if the time at which the duplicate application starts is c: all data packets in the statistical period T are transmitted in a non-duplicate mode, and the data transmission of the statistics can be identified as the non-duplicate mode or not labeled;

if the time when the replication starts is b (or the time when the replication is applied is from a to b): if only a part of the data packets in the statistical period T are duplicate transmission, at least one of the following methods can be applied:

not counting the data of the current period T;

identifying the data transmission of the statistic as duplicate;

identifying that the data transmission of the statistic comprises duplicate;

and marking the proportion of the time length occupied by the duplicate transmission/the time occupied by the duplicate transmission, or the number of the data packets transmitted by the duplicate transmission/the proportion occupied by the data packets transmitted by the duplicate transmission, or the proportion occupied by the accumulated data amount transmitted by the duplicate transmission/the accumulated data amount transmitted by the duplicate transmission in the current statistical period/data burst.

The second embodiment:

assume that each DRB starts repeat transmission, and the statistical granularity is for each terminal, taking statistics of per ue downlink data throughput with a statistical period of T as an example. If the UE transmits 3 DRBs 1, DRBs 2, and DRBs 3, the 3 DRBs correspond to different QCIs or 5 QIs. Wherein, the network has opened duplicate to DRB2, then can:

marking the current statistical result as duplication or including duplication;

note that the DRBs using duplicate in the data transmission in this statistic account for 1/3 of the DRBs of all statistics.

Example three:

assume that each data packet starts repeat transmission, and the statistical granularity is DRB, taking statistics of downlink data throughput of each DRB with a statistical period T as an example. If the UE transmits data with the duplicate turned on or off at packet granularity (e.g., PDCP SDU), then:

marking the data transmission of the current statistics as duplication or comprises duplication;

the number of SDUs/the ratio/the amount of data using the duplicate in the data transmission within the statistic is labeled as a part of the statistic result.

As shown in fig. 5, 10 data packets are transmitted in the statistical period, and 3 of them are transmitted by duplicate, the following contents can be labeled as part of the statistical result:

the proportion of data packets transmitted by duplicate is 3/10-30%;

the number of data packets transmitted by the duplicate is 3;

the total data volume of 3 packets transmitted by dupling (e.g. statistics for the data volume).

Further, identifying the retransmission information of the target data transmission by the retransmission layer two statistic of the target data transmission comprises:

Here, the retransmission time using the retransmission function may be a transmission time of all the data packets/DRBs using the retransmission function in the target data transmission, or a transmission time of the data packets/DRBs using the retransmission function and satisfying a preset statistical condition in the target data transmission.

In the embodiment of the present invention, when the retransmission information of the target data transmission is identified by the newly introduced duplicate transmission layer two statistic, only the statistical results after the duplication is turned on and before the duplication is turned off may be recorded, for example, only all the time/number of data packets/number of DRBs/data amount from the beginning to the end of DRBs/data packet transmission performed by applying the duplication are recorded, and the statistical period or statistical time period may be continuous or discontinuous in time.

The following describes an implementation of identifying retransmission information by using retransmission layer two statistics in combination with the fourth and fifth embodiments.

Example four:

assume that each DRB starts repeat transmission, and the statistical granularity is DRB, taking the uplink packet loss rate statistics of each DRB as an example. The statistic is used for counting the unsuccessfully received uplink PDCP packets at the base station side (eNB, gNB, gNB-CU/gNB-CU-UP and the like). The statistical method can be as follows:

Introducing new statistics for the duplicate may be, as in embodiment 1/2/3, setting a fixed statistical period T, marking the statistics in T as the length/ratio of time occupied by duplicate transmission, the number/data amount ratio of duplicate packets, etc., or starting the statistical period T after the beginning of the duplicate. As shown in fig. 6, when the duplicate transmission data is started, the statistical period T is started. And when the repeated transmission is closed, the T is ended, and the serial numbers of the data packets received by the base station in the period T are counted to be 4-7, 10, 11 and 12. The data packet with the intermediate sequence number of 8, 9 is not received. Therefore, the uplink packet loss rate in the current statistics period T is 2 (the number of lost packets)/9 (the number of packets that should be received) — 22.22%.

Further, in the layer two statistical method according to the embodiment of the present invention, in a case that the target data transmission employs a repeat transmission function, before identifying repeat transmission information of the target data transmission, the method further includes:

With reference to the fourth embodiment, as shown in fig. 6, the time when the retransmission starts to be applied is indicated, and here, the network side indicates to the terminal from which data packet the retransmission starts or stops, or indicates which data packets need to be retransmitted, so that the statistics result of the retransmission can be obtained more accurately.

Example five:

assume that each data packet starts repeat transmission, and the statistical granularity is DRB, taking the uplink packet loss rate statistics of each DRB as an example. As shown in fig. 7, the duplicate is currently the per packet open, and the packets 2, 4, 5, 8 to 12 are packets to which duplicate transmission is applied. The statistical period is set to be the total time length T or the total number M of data packets to which the duplicate application is applied.

Counting is started from the duplicate data packet 2, and only all time/data packet number/DRB number/data volume from the beginning to the end of data packet transmission by applying duplicate transmission can be counted;

for the uplink packet loss rate, in the statistical period in the embodiment of the present invention, there are 8 duplicate transmission data packets, where the data packets numbered 9 and 10 are not received at the base station side. Therefore, the uplink packet loss ratio in the current statistics period is 2 (packets numbered 9 and 10)/8 (total number of packets) ═ 25%.
