Network Transformation: TM Forum's Open API & Open Digital Architecture (ODA)

Network Transformation: TM Forum's Open API & Open Digital Architecture (ODA)

Majority global operators have been on the journey towards network transformation / cloudification for only 4-5 yrs now and due to challenges and complexities involved with network virtualization and cloudification, relatively very less progress has been made. However the speed of transformation has caught pace globally in the last 2 yrs as most operators plan for implementing 5G in their networks.

In order to ease the transition , many open source projects and industry associations have got created over the years with goal of easing virtualization journey for vendors & operators. One such industry association who has been leading the efforts for Digital Business Transformation has been TM Forum. 2 initiatives of TM Forum to ease network transformation include OpenAPIs & Open Digital Architecture(ODA).

OpenAPIs:

The OpenAPIs initiative started in 2016 and  involved collaboratively developing Rest APIs that can be used for scenarios to enabling service providers to transform their IT systems, improve operational agility and focussed at customer centricity, while externally delivering a practical approach to seamless end-to-end management of complex digital services. More than 50 OpenAPIs have been created and full list can be viewed at URL.

The APIs are in use by more than 7,000 software developers in over 1,200 companies worldwide. T Some of the companies using the Open APIs include AT&T, Deutsche Telekom, Axiata, Bharti Airtel, BT, China Mobile, China Unicom, Ericsson, Nokia, Globe, Huawei, IBM, MyRepublic, NTT-Group, Oracle, Orange, Telefonica, Telstra and Vodafone. Full List of signatories to the OpenAPI can be viewed here.

Open Digital Architecture:

In 2018, TM Forum launched Open Digital Architecture(ODA). ODA is a blueprint for modular, cloud-based and open digital platforms that can be orchestrated using AI.

Open Digital Architecture aims to create a market for innovative, standardized and interoperable software components by:
  • Replacing traditional operational and business support systems (OSS/BSS) systems with cloud-native software components.
  • Replacing traditional IT architectures with the Open Digital Architecture’s standardized plug-and-play components, data model and Open APIs.

The key principles of the Open Digital Architecture are outlined in the whitepaper from TM Forum.

As of June 2020, 30 companies have signed up for the Open API & ODA manifesto which includes: Amdocs, Netcracker Technologies, Nokia, Oracle Communications, BT, Deutsche Telekom, Telefonica, Telenor, Vodafone,Orange & Axiata.

With increasing traction of Cloud native network components, need for Open systems & improving Digital Experience for Customers Open API & Open Digital Architecture are definitely looking very promising.

Telefónica to deploy LTE in 2.6Ghz

Spain’s Telefónica announced LTE deployment at Mobile World Congress , saying it will use Alcatel Lucent’s LightRadio technology in the 2.6Ghz frequency band. Deployment is expected to begin in Chile and Brazil. According to the company, the service will provide download speeds of 100 Mbps, and between 40-60Mbps on upload. Telefónica explained that the difference in its deployment is that in the conventional deployment, radio base stations co-exist with 4G metro cells (small base stations incorporating antennas and radio) working on the same frequency and with no interference. During the announcement, Telefónica highlighted as the most significant feature the increased capacity to support 30 people browsing simultaneously with an average speed of 30Mbps. The telecom operator noted that the network supports speeds of up to 10 times those offered by the 3G network, with download speeds of 100Mbps, upload speeds of 40-60 Mbps and with latency times of around 20-25 mi...
