摘录自
摘自AMF
AMF 从用户设备 UE(N1 / N2参考点)接收所有与连接和会话相关的信息,但仅负责 处理连接和移动性管理任务。 与会话管理有关的所有消息都通过 N11 参考接口转发到会话管理功能(SMF)。
摘自3GPP 5G Security
Authentication Server Function (AUSF) keeps a key for reuse, derived after authentication, in case of simultaneous registration of a UE in different access network technologies, i.e. 3GPP access networks and non-3GPP access networks such as IEEE 802.11 Wireless Local Area Network (WLAN).
(认证服务器功能(ausf)在不同的接入网技术(即3gpp接入网和非3gpp接入网,如ieee 802.11无线局域网)中同时注册ue的情况下,保留在认证后导出的密钥以供重用。)
摘自
从协议栈角度出发
RR | Radio Resource | 无线资源 |
---|---|---|
MM | Mobile Management | 移动性管理 |
CC | Call Control | 呼叫控制 |
从流程角度出发
举个形象的比喻,接入层的信令是为非接入层的信令交互铺路搭桥的。通过接入层的信令交互在UE和CN之间建立起了信令通路,从而便能进行非接入层信令流程了。

MANO主要由VIM(virtualized infrastructure managers,基础设施虚拟化管理)、VNFM(virtualized network functions management,网络功能虚拟化管理)和编排(orchestrator)三个实体组成。MANO可以动态配置整个网络中的基础设施和功能,将硬件资源和虚拟网络相互映射,协助OSS/BSS的功能完成。首先,依据第三方需求,OSS/BSS可以生成网络切片用例(模板),包括了网络功能网元,以及网元之间的接口和网络资源。MANO可以根据此模板来申请所需要的网络资源,在此资源上生成网络功能模块接口。MANO完成对网络切片的实时跟踪,管理和监视网络切片的动态,根据业务情形对切片的资源进行动态调整,在结束服务的时刻回收此网络切片以及相应的资源。以此来高效的保障网络切片的服务,提高用户的整体体验感受。
