Resource pre-allocation method for reducing air interface time delay

Abstract

The invention discloses a resource pre-allocation method for reducing air interface time delay, which comprises a terminal, a base station and a resource pre-allocation module, and is characterized in that the resource pre-allocation module classifies and identifies the terminal according to service characteristics of the terminal reported by the base station; the resource pre-allocation module performs terminal grouping according to classification identifiers of the terminals and beam IDs, calculates the number of beams of each terminal group, and finally pre-allocates wireless resources according to the number of the beams of the terminal groups and a priority strategy of QoS level combination, so that the wireless resources are utilized to the maximum extent. According to the resource pre-allocation method for reducing the air interface time delay, grouping is carried out by fully utilizing a 5G MIMO wave beam and the service characteristics of the mMTC terminal, and wireless resource pre-allocation is carried out through a priority strategy, so that the wireless resources are utilized more effectively, the investment of an operator can be reduced, more base stations do not need to be deployed, and the wireless resources are utilized to the maximum extent.

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 time delay. Background technique [0002] The three major application scenarios of 5G include eMBB, URLLC, and mMTC. Among them, mMTC, as an 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. In this state, the base station retains the context information of the terminal, and the user plane bearer facing the core network is always 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 only be sent after transitioning from the idle state or inact...

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;
