In this step, the 5QI parameter of the SDAP data unit received by the SDAP entity is obtained, which provides a data basis for step 102.
And step 102, determining the quality parameters of the service with the same 5QI parameters.
The quality of service parameters may include parameters such as density of network devices, terminals connected to the network devices, and speed and reliability of data transmission between the network devices and the terminal devices, and the quality of service parameters may be used to describe performance of network management devices, minimization of Drive-Test (MDT), and the like.
It should be noted that, since 5G introduces a network architecture with a centralized unit-distributed unit (CU-DU) separation, and 5QI is only visible in the SDAP layer, steps 101 and/or 102 can be configured to be performed in the CUs.
As an optional implementation manner, the quality of service parameter includes a base station side quality of service parameter determined at the base station side and/or a terminal side quality of service parameter determined at the terminal side;
