5G独立组网SA模式下的驻网流程浅析
|
摘要
5G网络部署及建设对运营提出了新的要求,建设独立的5G网络或借助LTE进行联合组网是目前运营商需要考虑的问题。介绍了5G非独立组网和独立组网的两种网络架构,并重点分析了5G独立组网模式下终端小区搜索流程,同时对于需要在开网优化中给予重点关注的系统级参数予以说明,为5G网络的建设提供参考。
The 5 G network deployment and construction poses new requirements for operation. To construct the independent 5 G network or joint networking with LTE is the concern that should be considered by operators at present. Two network architectures of non-standalone and standalone 5 G are introduced. The terminal cell search process in the 5 G standalone mode is analyzed in detail. In addition, the key system-level parameters in the network optimization are elaborated. This work can provide useful reference to the construction of 5 G network.
