A resource pre-allocation method for reducing air interface delay

Abstract

The invention discloses a resource pre-allocation method for reducing air interface delay, comprising a terminal, a base station and a resource pre-allocation module. The resource pre-allocation module classifies and identifies the terminal according to service characteristics of the terminal reported by the base station; The classification identifier and beam ID of the terminal are grouped, and the number of beams in each terminal group is calculated. Finally, the pre-allocation of wireless resources is carried out according to the priority strategy of the combination of the number of beams of the terminal group and the QoS level, so as to maximize the use of wireless resource. The resource pre-allocation method for reducing the air interface delay of the present invention makes full use of the 5G MIMO beam and the service characteristics of the mMTC terminal for grouping, and pre-allocates the wireless resources through the priority strategy, so that the wireless resources are more effectively used, and the reduction of Operators invest and do not need to deploy more base stations, so as to maximize the use of wireless resources.

Description

technical field [0001] The invention relates to the technical field of resource management, in particular to a resource pre-allocation method for reducing air interface delay. Background technique [0002] The three major application scenarios of 5G include eMBB, URLLC, and mMTC. mMTC, as the application scenario of the Internet of Everything, mainly focuses on performance indicators such as wide connection, low latency, small packet data transmission, reliability, and wide coverage. At the same time, compared with LTE, 5G introduces a new inactive state in the RRC state. This state is that the base station retains the context information of the terminal, and the user plane bearer facing the core network has been maintained. [0003] For small packet data transmission, according to Release 16 and previous standard protocols, a signaling connection needs to be established first, and user plane data can be sent only after transitioning to the connected state through the idle s...

AI Technical Summary

Problems solved by technology

[0010] 1. The current standard only provides that user data can be transmitted on the user plane through wireless resource pre-allocation, but does not provide a specific wireless resource pre-allocation scheme

[0011] 2. More importantly, due to the preciousness of wireless resources, general operators will set the number of wireless resources that can be used for pre-allocation in the cell, that is, the threshold parameter. Because there are too many pre-allocated wireless resources, the access and service experience of other users It will be greatly affected, which will affect the overall performance of the cell; because the pre-allocated wireless resources may not be actually used by the terminal sometimes, it will also cause a waste of wireless resources in the cell;
