1、5G的系统结构？
5G系统结构采用NFV/SDN以支持数据连接和业务灵活部署, 促使基于业务的控制面网络功能和概念互动:
- 用户面功能和控制面功能分离, 允许独立的可扩展性,可演进性及可灵活部署.比如可选择采用集中式或者分布式的方式.
- 功能设计模块化, 比如采用灵活高效的网络切片.
- 无论在什么地方适用,都可以将相应的过程(网络功能之间的互动)定义为业务, 以便可以复用他们.
- 如果有需要都可以使相应的网络功能和其他的NF互动. 5G结构并没有排除中间功能帮助路由控制面信息. (比如 DRA).
- 缩小接入网络(AN)和核心网络(CN)的依赖性.这个结构是一个公共接入网AN连接汇聚的核心网. 而AN可以是不同的接入类型比如3GPP接入网和non-3GPP接入网.
- 支持统一的鉴全架构.
- 支持 #34;stateless#34; 网络功能NF, 这些网络功能的计算资源和存储资源解耦.
- 支持能力开放
- 同时支持本地和集中化的业务. 为了支持低延迟业务并访问本地数据网络,用户面功能部署需要尽可能的靠近介入网络AN.
- 在VPLMN支持基于LBO和家乡路由的漫游方式.
所有这些设想通过两种方式来实现：
- 基于业务service-based，控制面相关的网元功能实体能够授权其他网元来访问它的业务。
5G系统结构中包含如下基于业务service-based的接口
Namf: Service-basedinterface exhibited by AMF.
Nsmf: Service-basedinterface exhibited by SMF.
Nnef: Service-basedinterface exhibited by NEF.
Npcf: Service-basedinterface exhibited by PCF.
Nudm: Service-basedinterface exhibited by UDM.
Naf: Service-basedinterface exhibited by AF.
Nnrf: Service-basedinterface exhibited by NRF.
Nnssf: Service-basedinterface exhibited by NSSF.
Nausf: Service-basedinterface exhibited by AUSF.
Nudr: Service-basedinterface exhibited by UDR.
Nudsf: Service-based interfaceexhibited by UDSF.
N5g-eir: Service-based interface exhibited by 5G-EIR.
- 基于参考点reference point ，点对点网元功能业务之间互作用点。
5G结构中定义了如下参考点：
N1: Referencepoint between the UE and the AMF.
N2: Referencepoint between the (R)AN and the AMF.
N3: Referencepoint between the (R)AN and the UPF.
N4: Referencepoint between the SMF and the UPF.
N6: Referencepoint between the UPF and a Data Network.
N9: Referencepoint between two UPFs.
N5: Referencepoint between the PCF and an AF.
N7: Referencepoint between the SMF and the PCF.
N24: Referencepoint between the PCF in the visited network and the PCF in the home network.
N8: Referencepoint between the UDMand the AMF.
N10: Referencepoint between the UDM and the SMF.
N11: Reference point between the AMF andthe SMF.
N12: Reference point between AMF andAUSF.
N13: Reference point between the UDM andAuthentication Server function the AUSF.
N14: Reference point between two AMFs.
N15: Referencepoint between the PCF and the AMF in case of non-roaming scenario, PCF in thevisited network and AMF in case of roaming scenario.
N16: Reference point between two SMFs,(in roaming case between SMF in the visited network and the SMF in the homenetwork).
N17: Referencepoint between AMF and 5G-EIR.
N18: Referencepoint between any NF and UDSF.
N22: Reference pointbetween AMF and NSSF.
N27: Reference pointbetween NRF in the visited network and the NRF in the home network.
