O-RAN Motivation

O-RAN Motivation

For the past two decades, mobile communication has significantly helped social and economic growth around the world.

Going forward, future mobile solutions need to address different requirements based on their deployment regions and socio-economic environment.

While in Western Europe and North America specific network performance of mobile networks such as higher throughput and lower latency are required,

in Africa and rural parts of the world a completely different set of performance indicators are important; including deployments with less than perfect backhauls and low cost for deployment.

Considering these diverse sets of requirements, future mobile networks need to be dynamic enough to address these issues accordingly.

Mobile Operator Challenge

Mobile operators in developed countries continue to face higher data usage rates by subscribers.

In order to address this, mobile operators need to spend a lot on new equipment and services which increases CAPEX and OPEX.

This has significantly reduced profitability and forced mobile operators to find new ways of expanding the capacity of their networks while remaining profitable.

On the other extreme, in developing countries and rural areas of developed countries, mobile operators face the challenge of providing acceptable services while meeting their financial targets considering low average revenue per user (ARPU).

O-RAN Technology Basic

The future evolution of RAN will be toward dynamic functional splits.

While the gateway (aggregator) acts as a mediator between RAN and core network, the functionality of the RAN will be distributed between DUs and CUs as it is defined in 5G

In different scenarios, these elements can collapse together and create a single physical entity with different virtual functionalities.

He centralized baseband deployment is initially proposed to allow load-balancing between different base stations.

Therefore, in most cases DU will be collocated with RRH to conduct all computationally intense processing tasks.

Dynamic functional split between a CU and DUs will be the approach for 5G systems and beyond. While CUs will maintain BBU-like functionalities, DUs will be more than RRH in terms of processing capacities.

RAN Splits

As described in the previous section, the future evolution of RAN will be toward dynamic functional splits.

While a gateway/aggregator acts as a mediator between RAN and core network, the functionality of the RAN will be distributed between DUs and CUs.

In different scenarios, these elements can collapse together and create a single physical entity with different virtual functionalities.

O-RAN Architecture

The reference O-RAN architecture introduced by the Open Radio Access Network Alliance was envisioned with an eye towards next-gen RAN infrastructure with virtualized RAN on open hardware and artificial intelligence intrinsic to radio control.

Functional modules of O-RAN architecture include the RIC non-Real-Time layer to perform operations including policy management and analytics, and the RIC near Real-Time layer to perform time sensitive functions such

Interference detection.

Layer integration allows the RIC near Real-Time layer to benefit from intelligently trained models and real time control functions distributed by the RIC non-Real-Time layer.

The multi-RAT CU protocol stack, deployed on a virtualization platform, supports protocol processing for 4G or 5G while establishing security isolation and virtual resource allocation, among other functions. The open radio unit (O-RU) and open distributed unit (O-DU) elements are integrated through an O RAN fronthaul interface with a well defined lower level split (LLS) that supports eCPRI and RoE. Further definition and standardization of these interfaces will drive interoperability, competition and innovation into the O-RAN supply chain.

O-RAN Benefits

Operational efficiencies have been realized through past RAN innovations such as cloud RAN (cRAN), but previous advancements did not free operators from vendor lock-in.

By enabling an open, multi-vendor RAN ecosystem, O-RAN introduces cloud-scale economies and competition to the RAN.

Marketplace factors, combined with a more elastic and flexible RAN architecture that is already taking shape through virtualization, can enable much faster time to market (TTM) than was previously possible.

Moving away from the vendor-specific RAN paradigm not only enables more flexibility for operators, it also minimizes the “secret sauce” that leaves them reliant on a single vendor for all aspects of RAN implementation and optimization.

Competition and proliferation resulting from of new entrants can potentially drive down O-RAN equipment costs. The inter-carrier, interoperability aspects of Open RAN can also be used to increase efficiencies for existing LTE networks as they continue to incorporate the virtualization and disaggregation that are prerequisite 5G RAN deployment.
