Abstract

The invention provides a wireless side transmission delay acquisition method and device, and belongs to the technical field of wireless communication. The method comprises the steps that when UE is switched to a second base station from a first base station, a first data packet sent by the second base station is received, the first data packet carries a first time point, and the first time point is a time point when the first data packet arrives at a wireless interface protocol layer of the first base station; the first time point is acquired; a time point at which the first data packet leavesthe UE wireless interface protocol layer is obtained as a second time point; and according to the first time point and the second time point, the wireless side transmission delay is obtained when thefirst data packet is switched. According to the method and the device, the sending time and the arrival time of the data packet are obtained by recording the time point when the data packet arrives at the wireless interface protocol layer of the first base station and the time point when the data packet leaves the wireless interface protocol layer of the UE in the switching process, so that the wireless side transmission delay of the data packet in the switching process is accurately obtained.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular, to a method and device for acquiring transmission delay on a wireless side. Background technique [0002] With the development of wireless communication technology, technologies such as automatic driving, intelligent manufacturing, and remote control are gradually emerging. How to ensure low latency and high reliability in the communication process has become a technical problem for mobile communication networks. The industry and standardization organizations have begun to actively study how to support these future services. The 3rd Generation Partnership Project (3GPP) is the main standardization promoter. This technical problem is solved in the fifth generation (5thGeneration, 5G) mobile It also exists in the communication network. 3GPP TR 38.913 requires 5G service user plane air interface delay to be "enhanced mobile broadband (enhanced Mobile Broad...
