Description

Packet loss rate calculation method, network device and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a packet loss rate calculation method, a network device, and a terminal.

Background

In the fourth generation (4)^thGeneration, 4G) mobile communication system, or Dual Connectivity (DC) system called Long Term Evolution (LTE) system, includes three different bearer separation types, specifically: master Cell Group (MCG) bearers, split (split) bearers and Secondary Cell Group (SCG) bearers. In the fifth generation (5)^thGeneration, 5G) mobile communication system, or referred to as a DC architecture of a New Radio (NR) system, not only supports MCG and SCG, but also further supports a Packet Data Convergence Protocol (PDCP) copy function, so that different bearer types (bearer types) are generated, and the bearer types supported in the DC architecture of the specific 5G system include the following:

as shown in fig. 1, the MCG carries a bearer, and the bearer corresponds to MCGs of entities such as PDCP, Radio Link Control (RLC), and Medium Access Control (MAC).

As shown in fig. 1, the SCG carries the SCG corresponding to the PDCP, RLC and MAC entities.

As shown in fig. 2, the Split bearer has 1 cell group of the PDCP entity corresponding to the bearer, that is, the PDCP entities corresponding to the bearer are all in the MCG or SCG, and the 2 RLC entities and the 2 MAC entities corresponding to the bearer are respectively in different cell groups, that is, one of the RLC entities or MAC entities corresponding to the bearer is in the MCG, and the other is in the SCG.

As shown in fig. 3, a Duplicate (Duplicate) bearer has 1 PDCP entity, 2 RLC entities and 1 MAC entity corresponding to the bearer in 1 cell group, that is, 1 PDCP entity, 2 RLC entity and 1 MAC entity corresponding to the bearer are in an MCG or an SCG.

In addition, in order that the network device can better configure parameters for configuring the relevant radio resources to the terminal, the network device in the NR system may obtain the result of Layer 2(Layer-2, L2) measurement by self-calculation or by means of reporting by the terminal. Wherein the self-calculated L2 measurement of the network device comprises: physical Resource Block (PRB) usage rate (use), Random Access Preamble (Received Random Access Preamble), Number of active terminals (Number of active UEs), downlink Packet Delay rate (Packet Delay), Packet Loss rate (Data Loss), Scheduled IP Throughput (Scheduled IP Throughput), Scheduled Minimization Drive Test (MDT) IP Throughput (Scheduled IP Throughput for MDT), Data Volume (Data Volume), and Shared network Data Volume (Data Volume for Shared network). L2 measurements reported by the terminal include the uplink Packet Delay (Packet Delay).

In addition, a preprocessing function is added in the 5G system, and specifically, when the terminal does not receive an uplink transmission authorization sent by the network device, the terminal may preprocess the Data and generate a corresponding Data Packet to be sent, such as a Packet Data Unit (PDU) of the MAC layer.

Further, a Quality-of-Service (QoS) network device side indication mechanism is introduced in the 5G system, and QoS indication information, such as a QoS flow ID (QoS flow ID), of an IP data flow of a terminal needs to be added in the transmission process of uplink and downlink data. As shown in fig. 4, a Service Data Adaptation Protocol (SDAP) layer is located on a PDCP layer, 1 SDAP entity corresponds to 1 PDU session, 1 SDAP entity corresponds to multiple Data Radio Bearers (DRBs), that is, 1 SDAP entity corresponds to multiple PDCP entities, and a network device configures a corresponding Service flow (flow) for each DRB. Among them, a Service Data Unit (SDU) is a Data packet received by a certain protocol layer from a higher protocol layer, or a Data packet transmitted to a higher protocol layer, for example, a Data packet received by a MAC layer from an RLC layer is called a MAC SDU. A PDU is a packet sent by a certain protocol layer to a lower protocol layer, or a packet received from a lower protocol layer, for example, a packet sent by a MAC layer to a physical layer is called a MAC PDU.

Due to the introduction of different bearer types, preprocessing functions and a new protocol SDAP layer, the packet loss rate of data transmission cannot be accurately determined by adopting a packet loss rate calculation mode in the traditional system.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 5, the packet loss rate calculation method according to the embodiment of the present invention is applied to a network device, and specifically includes the following steps:

step 51: and acquiring at least one of the service bearing type and the data packet type under current transmission.

The service bearing type is the bearing type of the current data transmission, and the data packet type is the data packet type of the physical layer of the current data transmission. Specifically, the service bearer types include: one of an MCG bearer, an SCG bearer, an MCG leg of a split bearer, an SCG leg of a split bearer, and a duplicate bearer. Further, the packet type is used to indicate packets in different physical layers, and specifically includes: at least one of a data packet of service data units, SDUs, in a service data adaptation protocol, SDAP, in a SDAP entity, a data packet of SDUs, in a packet data convergence protocol, PDCP, entity (available to a network entity without a SDAP entity), a data packet of PDUs, in a PDCP entity (available to a network entity without a SDAP entity), a data packet of SDUs, in a radio link control, RLC, entity (available to a network entity without a PDCP entity, carried by split), a data packet of PDUs, in a RLC entity (available to a network entity without a PDCP entity, carried by split), a data packet of SDUs, in a medium access control, MAC, entity (available to a network entity without a RLC entity, carried by split), and a data packet of PDUs, in a MAC entity (available to a network entity without a RLC entity, carried by split).

Step 52: and determining the packet loss rate under the current transmission according to at least one of the service bearing type and the data packet type.

Here, the network device may determine the packet loss rate of current transmission based on the service bearer type, may also determine the packet loss rate of current transmission based on the data packet type, and may also determine the packet loss rates of different service bearer types under current transmission based on the data packet type.

After the network device determines the packet loss rate in the current transmission, it may configure transmission resources and transmission modes for the next transmission according to the packet loss rate.

Because the network device determines the packet loss rate of the current transmission based on at least one of different service bearer types and different data packet types, the network device is applicable to determining the packet loss rate in each scene in a 5G system without being limited by a specific scene, and thus, the network device configures corresponding transmission resources and transmission modes for the next transmission based on the packet loss rate to better conform to an actual transmission environment, for example, the data packet is sent on a better transmission path, or the wireless resource configuration is changed to reduce the packet loss rate, thereby improving the reliability of data packet sending and the like.

Wherein step 52 comprises: and calculating the packet loss rate in the specific time interval under the current transmission according to the number of the discarded data packets and the number of the received data packets in the specific time interval of at least one of the service bearing type and the data packet type. The specific time interval is a calculation period of the packet loss rate.

Wherein, the packet loss rate includes: at least one of a packet loss rate of a specific terminal, a packet loss rate based on a quality of service Class Identifier (QCI), a packet loss rate based on a bearer type, a packet loss rate of a transmission path based on a bearer type, a packet loss rate based on a bearer, and a packet loss rate based on a quality of service QoS flow. That is, the network device can calculate a packet loss rate for a certain terminal, or a packet loss rate for a certain QCI, or a packet loss rate for a certain service bearer type, or a packet loss rate for a transmission path of a certain service bearer type, or a packet loss rate for a certain bearer, or a packet loss rate for a certain QoS flow, based on the number of discarded data packets and the number of received data packets of different service bearer types or different data packet types in a specific time interval.

Specifically, the types of packet loss rates include: at least one of a packet loss rate for a particular target and a packet loss rate associated with a particular bearer type. Wherein, the packet loss rate of the specific target comprises: at least one of a packet loss rate of a specific terminal, a packet loss rate based on a quality of service Class Identifier (QCI), and a packet loss rate based on a quality of service QoS flow. Packet loss rates associated with a particular bearer type include: the packet loss rate based on the bearer type, the packet loss rate based on the transmission path of the bearer type, and the packet loss rate based on the bearer. It is worth pointing out that the packet loss rate of a specific target can be calculated by any one or any plurality of different types of data packets, that is, the packet loss rate of a specific target can be calculated by different data packets of different physical layers, for example: the packet loss rate of a certain terminal may be calculated by at least one of a data packet of SDU in the SDAP entity, a data packet of PDU in the SDAP entity, a data packet of SDU in the PDCP entity, a data packet of PDU in the PDCP entity, a data packet of SDU in the RLC entity, a data packet of PDU in the RLC entity, a data packet of SDU in the MAC entity, and a data packet of PDU in the MAC entity, and it is worth pointing out that the packet loss rate of other specific targets may also be calculated by at least one of the above 8 different types of data packets, and therefore, it is not described herein. Similarly, the packet loss rate associated with a particular bearer type may also be calculated using any one or any plurality of different types of data packets, i.e., the packet loss rate associated with a particular bearer type may be calculated using different data packets of different physical layers, for example: the packet loss rate of a certain bearer type (e.g., MCG bearer) may be calculated by at least one of a data packet of SDU in the SDAP entity, a data packet of PDU in the SDAP entity, a data packet of SDU in the PDCP entity, a data packet of PDU in the PDCP entity, a data packet of SDU in the RLC entity, a data packet of PDU in the RLC entity, a data packet of SDU in the MAC entity, and a data packet of PDU in the MAC entity.

Further, how to determine the packet loss rate of the current transmission according to different service bearer types or different data packet types will be further described below with reference to specific application scenarios.

In a first scenario, a network device calculates a packet loss rate of downlink data, which means that the network device calculates a packet loss rate of non-air-interface downlink transmission.

Specifically, when the current transmission is downlink transmission, the step of calculating the packet loss rate in the specific time interval according to the number of discarded packets and the number of received packets in different service bearer types or different data packet types in the specific time interval includes: and calculating the downlink data packet loss rate in the specific time interval according to the number of the discarded downlink data packets and the number of the received data packets before the air interface transmission is started under different service bearing types or different data packet types in the specific time interval.

Further, the network device may refer to a formula

And calculating the packet loss rate of the downlink data in a specific time interval.

Wherein, M (T, qci) represents a downlink data packet loss rate within a specific time interval T under current transmission; the ddsc (T, qci) represents the number of downlink packets discarded before the transmission of the air interface is not started in a specific time interval T; n (T, qci) represents the number of packets received before transmission over the air interface has not started within a specific time interval T.

The type of the downlink data packet loss rate includes one or more of the following types: a downlink data packet loss rate of a certain terminal, or a downlink data packet loss rate for a certain QCI, or a downlink data packet loss rate for a certain service bearer type (such as an MCG bearer, an SCG bearer, a split bearer, or a duplicate bearer), or a downlink data packet loss rate for a transmission path of a certain service bearer type (such as each branch path of a split bearer or each branch path of a duplicate bearer), or a downlink data packet loss rate for a certain bearer, or a downlink data packet loss rate for a certain QoS flow.

And in the second scenario, the network equipment calculates the data packet loss rate of the computing data.

When the current transmission is uplink transmission, according to the number of discarded data packets and the number of received data packets under different service bearer types or different data packet types in a specific time interval, the step of calculating the packet loss rate in the specific time interval under the current transmission comprises the following steps: and calculating the uplink data packet loss rate in a specific time interval according to the number of missing data packets and the total data packet number submitted to the higher-layer protocol entity by the current protocol entity under different service bearing types or different data packet types in the specific time interval.

The current protocol entity refers to a certain layer entity in each protocol layer in the 5G system, and specifically, the current protocol entity is: SDAP entity, PDCP entity, RLC entity or MAC entity.

Further, the number of missing data packets when the current protocol entity is delivered to the higher layer protocol entity within the specific time interval is determined according to the sequence number lost in the total data packets delivered to the higher layer protocol entity by the current protocol entity within the specific time interval. That is, the ddsc (T, qci) may be determined by the sequence number lost in the total data packets submitted to the higher layer protocol entity by the current protocol entity within the specific time interval, specifically, may be determined by counting the sequence number lost in the total data packets submitted to the higher layer protocol entity by the current protocol entity within the specific time interval T, and if the number range of the "total data packets submitted to the higher layer protocol entity" is [1, 10], and if the sequence numbers with SN numbers of 5 and 6 are lost, the number of the "missing data packets" is determined to be 2.

Further, the total number of data packets submitted from the current protocol entity to the higher layer protocol entity within a certain time interval is determined according to the sequence number of the data packets in the current protocol entity. I.e. N (T, qci) may be determined by the sequence number of the data packet in the current protocol entity, specifically, may be determined by counting the sequence number of the data packet of the current protocol entity, such as the initial SN number 1 and the final SN number 10, and then the total number of the data packets is 10.

The type of the uplink data packet loss rate includes one or more of the following types: an uplink data packet loss rate of a certain terminal, or an uplink data packet loss rate for a certain QCI, or an uplink data packet loss rate for a certain service bearer type (such as an MCG bearer, an SCG bearer, a split bearer, or a duplicate bearer), or an uplink data packet loss rate for a transmission path of a certain service bearer type (such as each branch path of a split bearer or each branch path of a duplicate bearer), or an uplink data packet loss rate for a certain bearer, or an uplink data packet loss rate for a certain QoS flow.

The current protocol entity refers to an entity in a certain layer of protocol layers in the 5G system, and specifically, the current protocol entity is: SDAP entity, PDCP entity, RLC entity or MAC entity. A higher layer protocol entity refers to an entity that is higher layer than the current protocol entity.

Specifically, the terminal may refer to a formula

Wherein, M (T, qci) represents a downlink data packet loss rate in a specific time interval T; the Ddisc (T, qci) represents the number of missing data packets when different service bearing types or different data packet types are delivered from the current protocol entity to the higher-layer protocol entity in the time interval T; n (T, qci) represents the total number of data packets submitted from the current protocol entity to the higher layer protocol entity under different traffic bearer types or different data packet types within a specific time interval T.

In a fourth scenario, the packet loss ratio is calculated by the terminal and reported to the network device side, and before the network device receives the downlink data packet loss ratio calculated and reported by the terminal in the fourth scenario, the method further includes: and sending configuration information related to the downlink data packet loss rate to the terminal.

The above embodiment describes the packet loss rate calculation method of the present invention from the network device side, and the following embodiment further describes the packet loss rate calculation method of the terminal side with reference to the accompanying drawings.

As shown in fig. 8, the method for calculating a packet loss rate according to the embodiment of the present invention is applied to a terminal, and specifically includes the following steps:

step 81: and receiving at least one of a service bearing type and a data packet type which are sent by the network equipment and used for calculating the downlink data packet loss rate.

Here, the terminal determines the service bearer type and the data packet type according to the indication of the network device. The service bearing type is the bearing type of the current data transmission, and the data packet type is the data packet type of the physical layer of the current data transmission. Specifically, the service bearer types include: one of an MCG bearer, an SCG bearer, an MCG leg of a split bearer, an SCG leg of a split bearer, and a duplicate bearer. Further, the packet type is used to indicate packets in different physical layers, and specifically includes: at least one of a data packet of service data units, SDUs, in a service data adaptation protocol, SDAP, in a SDAP entity, a data packet of SDUs, in a packet data convergence protocol, PDCP, entity (available to a network entity without a SDAP entity), a data packet of PDUs, in a PDCP entity (available to a network entity without a SDAP entity), a data packet of SDUs, in a radio link control, RLC, entity (available to a network entity without a PDCP entity, carried by split), a data packet of PDUs, in a RLC entity (available to a network entity without a PDCP entity, carried by split), a data packet of SDUs, in a medium access control, MAC, entity (available to a network entity without a RLC entity, carried by split), and a data packet of PDUs, in a MAC entity (available to a network entity without a RLC entity, carried by split).

Step 82: and calculating the packet loss rate of the downlink data according to at least one of the service bearing type and the data packet type.

Here, the terminal may determine the packet loss rate of current transmission based on the service bearer type, may also determine the packet loss rate of current transmission based on the data packet type, and may also determine the packet loss rates of different service bearer types under current transmission based on the data packet type. Wherein, the packet loss rate here includes: at least one of a packet loss rate of a specific terminal, a packet loss rate based on the quality of service class identifier QCI, a packet loss rate based on the bearer type, a packet loss rate of a transmission path based on the bearer type, a packet loss rate based on the bearer, and a packet loss rate based on the quality of service QoS flow.

Step 83: and sending the downlink data packet loss rate to the network equipment.

After the terminal calculates the downlink data packet loss rate, the terminal sends the downlink data packet loss rate to the network equipment so that the network equipment performs transmission resource configuration and transmission mode configuration of next transmission to optimize the network.

Wherein, the step 82 specifically comprises: and calculating the packet loss rate of the downlink data in the specific time interval according to the number of missing data packets and the total number of data packets when the data packets are submitted from the current protocol entity to the higher-layer protocol entity under different service bearing types or different data packet types in the specific time interval.

The current protocol entity refers to an entity of a certain layer of protocol layers in the 5G system, and specifically, the current protocol entity is: SDAP entity, PDCP entity, RLC entity or MAC entity. A higher layer protocol entity refers to an entity that is higher layer than the current protocol entity.

Specifically, the terminal may refer to a formula

Further, before step 83, the method further comprises: and receiving configuration information which is sent by the network equipment and is related to the downlink data packet loss rate. Wherein the configuration information includes: at least one of a measurement quantity identifier, a measurement object identifier, and a trigger reporting configuration.

Each configuration in the triggered reporting configuration includes at least one of a calculation time window of the downlink data packet loss rate, a reporting period of the downlink data packet loss rate, and a packet loss rate threshold of the downlink data packet loss rate, where the calculation time window of the downlink data packet loss rate is the specific time interval, and the length of the calculation time window may be set according to actual needs, for example, 10ms, and further, the size of the calculation time window may be predefined by a protocol. The threshold of the downlink data packet loss rate may indicate a threshold in each triggered reporting configuration, where the threshold is specifically a proportion, such as 10%. The reporting period of the downlink data packet loss rate may indicate a time period, such as 50ms, for each triggered reporting configuration to perform periodic reporting.

Specifically, the reporting configuration is triggered to trigger the reporting behavior of the terminal, and specifically, when the reporting conditions for triggering the reporting configuration indication are different, the reporting occasions of the terminal are different. In the following, this embodiment will introduce a reporting mechanism of a terminal in combination with different trigger reporting configurations.

Specifically, when the triggered reporting configuration includes a configuration for periodic reporting, step 83 is: and sending the downlink data packet loss rate to the network equipment according to the period configured in the configuration information. For example, the network device indicates that the periodic reporting period of the terminal is 10ms, and then the terminal sends the downlink data packet loss rate calculated by the terminal to the network device according to the 10ms period.

Specifically, when the triggering report configuration includes a configuration in which the downlink data packet loss rate exceeds the first threshold value, step 83 is: and measuring according to the configuration information, and sending the downlink data packet loss rate to the network equipment when the downlink data packet loss rate exceeds a first threshold value. For example, when the network device indicates that the downlink data packet loss rate is higher than 10%, the network device triggers reporting, and then the terminal sends the downlink data packet loss rate to the network device when determining that the downlink data packet loss rate is higher than 10%, and does not perform reporting processing when determining that the downlink data packet loss rate is lower than 10%.

Specifically, when the report triggering configuration includes a configuration in which the downlink data packet loss rate is lower than the second threshold value, step 83 is: and measuring according to the configuration information, and sending the downlink data packet loss rate to the network equipment when the downlink data packet loss rate is lower than the second threshold value. For example, when the network device indicates that the downlink data packet loss rate is lower than 5%, the network device triggers reporting, and then the terminal sends the downlink data packet loss rate to the network device when determining that the downlink data packet loss rate is lower than 5%, and does not perform reporting processing when determining that the downlink data packet loss rate is higher than 5%.

If the network device indicates that the downlink data packet loss rate is lower than 5% and the downlink data packet loss rate is higher than 10%, the terminal sends the downlink data packet loss rate to the network device when determining that the downlink data packet loss rate is lower than 5% or determining that the downlink data packet loss rate is higher than 10%, and does not perform reporting processing when determining that the downlink data packet loss rate is higher than 5% and lower than 10%.

Specifically, when the triggering report configuration includes a configuration that is reported periodically after the downlink data packet loss rate exceeds a third threshold, step 83 is: and measuring according to the configuration information, and when the packet loss rate of the downlink data exceeds a third threshold value, sending the packet loss rate of the downlink data to the network equipment according to a period configured in the configuration information. For example, when the network device indicates that the downlink data packet loss rate is higher than 10%, reporting is performed according to a period of 10ms, and then when determining that the downlink data packet loss rate is higher than 10%, the terminal sends the downlink data packet loss rate to the network device according to the period of 10ms, and when determining that the downlink data packet loss rate is lower than 10%, no reporting is performed.

Specifically, when the triggering reporting configuration includes a configuration that is reported periodically after the downlink data packet loss rate is lower than the fourth threshold, step 83 is: and measuring according to the configuration information, and when the packet loss rate of the downlink data is measured to be lower than the fourth threshold value, sending the packet loss rate of the downlink data to the network equipment according to the period configured in the configuration information. For example, when the network device indicates that the downlink data packet loss rate is lower than 5%, reporting is performed according to a period of 10ms, then the terminal sends the downlink data packet loss rate to the network device according to the period of 10ms when determining that the downlink data packet loss rate is lower than 5%, and does not perform reporting processing when determining that the downlink data packet loss rate is higher than 5%.

If the network device indicates that the downlink data packet loss rate is lower than 5% and the downlink data packet loss rate is higher than 10%, reporting the downlink data packet loss rate according to a period of 10ms, and when the terminal determines that the downlink data packet loss rate is lower than 5% or determines that the downlink data packet loss rate is higher than 10%, sending the downlink data packet loss rate to the network device according to the period of 10ms, and when the downlink data packet loss rate is higher than 5% and lower than 10%, not reporting. It should be noted that different reporting configurations in the triggered reporting configuration can be combined arbitrarily as long as no reporting collision occurs.

In the packet loss rate calculation method according to the embodiment of the present invention, the terminal receives at least one of the service bearer type and the data packet type sent by the network device, so as to calculate the packet loss rate according to the at least one of the service bearer type and the data packet type, and is applicable to various application scenarios in the 5G system, so as to ensure that the accurate packet loss rate in the 5G system is obtained through calculation, and further send the packet loss rate to the network device, so that the network device configures optimized transmission resources and transmission modes for the next transmission, for example, sends the data packet on a better transmission path, or changes the wireless resource configuration to reduce the packet loss rate, thereby improving the reliability of sending the data packet, and the like.
