Description
本申请涉及但不限于通信领域。
伴随着移动通信的发展,用户的需求越来越广泛,未来用户体验是多终端、多应用和高带宽的交织和融汇。据预测,未来支持的设备在数量上还是业务速率上都将是目前的10到100倍,而有些低时延超可靠业务要求的端到端时延将缩短到目前的五分之一。因此,网络发展需要更高带宽、更低时延、更高的可靠性和更强的智能化能力,而当前的网络难以满足未来业务全面提升的需求。
目前一些致力于研究5G的组织如Metis在一些公开的文档中提出了5G的架构。5G的架构有如下特点:聚焦于网络功能而不是网络实体/节点,网络功能组件化,基于用例来进行功能组件的组织,接口定义为功能组件的接口而不是网络实体的接口。5G的功能大体分为几个部分:中心管理实体(Central Management Entities),无线节点管理(Radio Node Management),空中接口。由于5G的业务形态和场景是多样化的,为了满足各种需求,需要有多种类型的小区存在,从网络制式上来讲,会存在2G、3G、4G、5G小区,从覆盖范围上来讲,会存在宏小区,微小区,超密集小区UDN,因此会存在多种无线接入技术融合的问题。采用多种无线技术融合可以有效地利用频谱等网络资源,一个明显的优势就是可以为用户提供超高速业务,而如何来提供这种超高速业务目前还没有公开的方案。
