III. Dynamic vRAN and Air Interface Algorithms Working Group


The vRAN working group is managed by Doron Solomon from ASOCS.

Main R&D tasks are dynamic vRAN and air interface algorithms, as well as future innovative topics.
The group has raised related topics that are not covered in 3GPP forums, but are well discussed, in xRAN, TIP, CORD, etc.  

The group is focused on tasks related to SD-RAN such as: NFV, SDN, orchestration and management, separation, multiple
operators, Open Source, etc. ASOCS, ADVA and Telrad are developing the virtualized part of the SD-RAN. The vRAN group is
addressing the 5G SD-RAN architecture to execute ideas such as Network Slicing, HetNET, with adaptive management for
maximum utilization of resources. 

The group works in accordance with 3GPP standards, smoothly deployed with ONF, ONAP, etc., and in compliance with LSO
as part of the vRAN domain. Advanced local orchestration and management of both NFV and the RAN itself is required for
implementing Content Awareness Function RAN, and QoS-aaS in different types of Network Slicing (Content Awareness,
Application Function Requests, UE requests, etc.), that is based on HetNet with multiple operators. 

Such an architecture requires new network security solutions, and advanced implementation that doesn’t exist today,
although it is covered in the 3GPP protocols and scenarios. 

The above topics are new, and elaboration of the scenarios can be done, and since the consortium includes several companies in
the vRAN/NFV/SDN domains, this work group was established to deal with developing the appropriate air-interfaces, and dynamic
algorithms for such future SD-RAN. The working group has an advantage in developing 5G sub-systems that can be tested in dual-
connectivity mode in accordance with the standard, and therefore is expected to become the market leaders solution that will
impact 5G deployments in the future.

The vRAN working group aims to start testing and integration of the different modules that are developed by the members of the
group as soon as possible, they have already shown successful integration between part of the modules. 

One of the main features of the vRAN architecture is the ability to easily implement different functional splits. This feature enables
broader interoperability such as support of eCPRI FH / RoE FH (IEEE-1914), and older interfaces like CPRI ORI (this is one of the
reasons why the group is also examining non-3GPP groups for interfaces like xRAN, TIP, ETSI, which could lead to future
contributions to the standard). 

The advantages of virtualizing the RAN include dynamic allocation of network resources, with ability to scale at any given time,
and the ability to scale automatically – meaning that a certain vBS that needs more resources could give the orchestrator the
specification of the daughter vBS he needs to create so that it can be optimally integrated into the system.
