Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

The inventor researches and discovers that network performance indexes which can be monitored by the current 5G network are limited, only packet loss rate, number of on-line terminals, uplink average time delay and the like can be monitored, and the requirement of monitoring the QoS of the 5G network cannot be well met. For example, in an industrial application scenario with a deterministic transmission requirement, the delay jitter is an important index for measuring the deterministic transmission, and the prior art does not support network monitoring of the delay jitter. For example, the downlink radio access network delay is an important component of the end-to-end delay, and is an important index for measuring whether the requirement of the user on the data delay is met, whereas the prior art only supports monitoring a part of the downlink radio access network delay, namely, the downlink PDCP reordering delay and the terminal side RLC layer delay are lacked.

Some embodiments of the measurement method of the present disclosure are first described in conjunction with fig. 1.

As shown in fig. 1, the method includes steps S101 to S108, and an application scenario includes a terminal, a base station, a trace collection entity TCE, an operation and maintenance system OAM, and an access and mobility management function AMF.

In step S101, the base station receives terminal side downlink PDCP packet measurement indication information sent by the network device.

In an NR scene, a base station receives MDT configuration information sent by OAM or AMF; in an LTE scenario, a base station receives MDT configuration information sent by OAM or MME. The MDT configuration information includes terminal side downlink PDCP packet measurement indication information. Wherein, the downlink PDCP packet measurement indication information of the terminal side comprises: capability indication information of terminal side downlink PDCP grouping time delay measurement and capability indication information of terminal side downlink PDCP grouping time delay jitter measurement.

In step S102, the base station transmits a terminal capability query message to the terminal.

And the terminal measures the downlink PDCP packet delay of the terminal side according to the measurement configuration information, wherein the downlink PDCP packet delay of the terminal side represents the time from the successful reception of the transmission block by the terminal to the departure of the PDCP SDU from the upper service access point of the PDCP. For example, the terminal calculates the downlink PDCP packet delay at the terminal side by the following notations:

wherein, T represents a measurement time period, i represents a PDCP SDU identifier received by the terminal in the T time period, m (T) represents a downlink PDCP packet delay average value at the terminal side, i (T) represents a total number of PDCP SDUs received by the terminal in the T time period, T1(i) represents a time point when the ith PDCP SDU leaves the PDCP upper service access point, and T2(i) represents a time point when the UE successfully receives a transport block corresponding to the ith PDCP SDU. And successfully receiving the transmission blocks of all the RLC SDU segments corresponding to the ith PDCP SDU, wherein the time point of the transmission block of the RLC SDU segment successfully received at last is taken as the standard.

And the terminal measures the downlink PDCP packet delay jitter of the terminal side and the uplink PDCP packet delay jitter of the terminal side according to the measurement configuration information, wherein the downlink PDCP packet delay jitter of the terminal side represents the statistical variance of the downlink PDCP packet delay in the measurement time period, and the uplink PDCP packet delay jitter of the terminal side represents the statistical variance of the downlink PDCP packet delay in the measurement time period.

Those skilled in the art can understand that the time unit of the downlink PDCP packet delay, the downlink access network delay, and the delay jitter on the terminal side may be 0.1ms, 0.01ms, 1 μ s, 0.1 μ s, or an integer number of sampling intervals Ts.

In step S107, the base station calculates a performance index of the downlink radio access network based on the measurement report.

Under the NR scene, the base station calculates the time delay and the time delay jitter of the downlink access network corresponding to each QoS flow and 5QI according to the measurement result reported by the terminal, the performance measurement result of the base station, the mapping relation between the DRB and the QoS flow and the mapping relation between the QoS flow and the 5 QI.

In step S108, the base station transmits the MDT measurement result to the network device.

In the NR scenario, the base station sends MDT measurement results to the TCE, OAM, or AMF, where the MDT measurement results include one or more of: the QoS flow identification, the 5QI identification, the QoS flow identification and the downlink radio access network time delay average value corresponding to the 5QI identification, the QoS flow identification and the downlink radio access network time delay jitter value corresponding to the 5QI identification, the QoS flow identification and the terminal side downlink PDCP group time delay average value corresponding to the 5QI identification, the QoS flow identification and the terminal side uplink PDCP group time delay jitter value corresponding to the 5QI identification, the QoS flow identification and the terminal side downlink PDCP group time delay jitter value corresponding to the 5QI identification and the network slice identification.

In an LTE scenario, a base station sends MDT measurement results to a TCE, OAM, or MME, where the MDT measurement results include one or more of the following: QCI, a downlink radio access network time delay average value corresponding to the QCI, a downlink radio access network time delay jitter value corresponding to the QCI, a terminal side downlink PDCP grouping time delay average value corresponding to the QCI, a terminal side uplink PDCP grouping time delay jitter value corresponding to the QCI, and a terminal side downlink PDCP grouping time delay jitter value corresponding to the QCI.

In the above embodiment, the network may monitor the performance indexes such as the downlink PDCP packet delay (including the downlink PDCP reordering delay and the terminal RLC layer delay), the complete downlink delay of the radio access network, the uplink delay jitter, and the like, and may determine whether the QoS requirement of the user is satisfied according to the monitoring result and perform network optimization in a targeted manner according to the achievement of the QoS index, thereby achieving network performance measurement more accurately and efficiently.

Because unpredictable variables exist in the conditions of terminal mobility and wireless channels, the air interface delay is often a part of the largest variable of the end-to-end delay, and monitoring the air interface delay and the air interface delay jitter has important significance for evaluating the real-time performance of a wireless access network. Compared with the prior art, the network can additionally obtain network performance measurement results such as downlink PDCP packet delay, downlink radio access network delay, delay jitter and the like at the terminal side, so that an operator or operation and maintenance personnel can remotely monitor the radio access network delay and delay jitter indexes in the network, evaluate the real-time performance and QoS guarantee condition of the radio access network, and do not need manual road test, thereby not only reducing the labor cost, but also having higher accuracy of measured data.

In addition, by monitoring the air interface delay of the terminal, the network may perform network optimization in a targeted manner, for example, when the average air interface delay of a certain terminal does not meet the QoS requirement, the base station may appropriately increase the scheduling priority of the terminal, for example, when the delays of a plurality of terminals in a certain network slice do not meet the QoS requirement, the network may appropriately expand the capacity of the slice or release some terminals.
