Abstract

The present application provides a method and device for acquiring link quality, including: a session management network element determines a monitoring link, and the monitoring link is used to detect the service quality of a service path between a first communication device and a second communication device ; The session management network element sends a first link quality report request to the first device, where the first link quality report request is used to instruct the first device to report the service quality information of the service path under the condition that the report policy is satisfied, The first device includes the first communication device and / or the second communication device; the session management network element receives a first link quality notification message from the first device, and the first link quality notification message includes the service The quality information and the identifier of the monitored link enable the first device to report the service quality information of the service path when the reporting policy is satisfied, which helps the network side obtain network performance.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a method and device for acquiring link quality. Background technique [0002] The fifth generation (5th Generation, 5G) communication system introduces Ultra-Reliable Low Latency Communication (URLLC) services, mainly including unmanned driving, industrial automation and other services that require low-latency and highly reliable connections. For low-latency, high-reliability services, the network needs to obtain Quality of Service (Qos) in a timely manner. In the current prior art, the radio access network (Radio Access Network, RAN) reports the transmission rate, which cannot meet the requirements of the URLLC service. [0003] In order to obtain network performance and service quality, 5G networks introduce Link Quality Awareness Protocol (LQAP) for URLLC services. How to notify the network side of the service quality events of the terminal and the user plane net...
