Problems solved by technology

Since the stratification strategy of the current network defines the D frequency band and the FDD1800MHz frequency band as the capacity layer, through the stratification strategy and parameter formulation of the FDD1800MHz frequency band, the FDD1800MHz frequency band can effectively absorb traffic and achieve the expected effect. However, the existing method has the following obvious disadvantages : The utilization rate of the FDD1800MHz frequency band is relatively high, and there is an uneven load with the D frequency band, which is not conducive to 5G service experience

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a layered method and system based on NSA networking architecture. Background technique [0002] With the construction and development of the 5G network, based on the 5G non-standalone (NSA) network structure, the FDD1800MHz frequency band is used as the 5G NSA anchor cell, and the D frequency band has evolved into a three-dimensional MIMO (three-dimensional MIMO) to further enhance the service carrying capacity. -demension Multiple-input Multiple-Output, 3DMIMO) cell. Since the stratification strategy of the current network defines the D frequency band and the FDD1800MHz frequency band as the capacity layer, through the stratification strategy and parameter formulation of the FDD1800MHz frequency band, the FDD1800MHz frequency band can effectively absorb traffic and achieve the expected effect. However, the existing method has the following obvious disadvantages : The uti...
