5G网络需要满足以下的需求：
●The RAN architecture shall support tight interworking between the new RAT and LTE.
✓Considering high performing inter‐RAT mobility and aggregation of data flows via at least dual connectivity between LTE and new RAT.
●The RAN architecture shall support connectivity through multiple transmission points, either collocated or non‐collocated.
✓The RAN architecture shall enable a separation of control plane signalling and user plane data from different sites.
✓The RAN architecture shall support interfaces supporting effective inter‐site scheduling coordination.
●Different options and flexibility for splitting the RAN architecture shall be allowed.
●The RAN architecture shall allow for deployment flexibility e.g. to host relevant RAN, CN and application functions close together at the edges of the network, when needed, e.g. to enable context aware service delivery, low latency services, etc...
●The RAN architecture shall allow for C‐plane/U‐plane separation.
●The RAN architecture shall allow deployments using Network Function Virtualization.
●The RAN architecture shall allow for the RAN and the CN to evolve independently.
●The RAN architecture shall allow for the operation of Network Slicing.
●The RAN architecture shall support sharing of the RAN between multiple operators.
●The design of the RAN architecture shall allow the deployment of new services rapidly and efficiently.
●The design of the RAN architecture shall allow the support of 3GPP defined service classes.
●The design of the RAN architecture shall enable lower CAPEX/OPEX with respect to current networks to achieve the same level of services.
●RAN‐CN interfaces and RAN internal interfaces (both between new RAT logical nodes/functions and between new RAT and LTE logical nodes/functions) shall be open for multi‐vendor interoperability.
●The RAN architecture shall support operator‐controlled sidelink(device‐to‐device) operation, both in coverage and out of coverage
