Hrvatski Telekom is the leading telecommunications provider in Croatia and a member of Deutsche Telekom group, providing fixed and mobile telephony, wholesale, internet and data services. In 2018, the company was on the lookout to replace their legacy AAA platform and introduce new services, with particular requirements for system stability, scalability and convergence (ability to support multiple access technologies through a single platform).

“Thanks to Logate’s industry knowledge and expertise, we were able to successfully
integrate the AAA solution in our multi-vendor environment.

During the project their
team showed remarkable skills in creating and deploying a stable solution in 3 data
centers, all working in active-active load sharing mode.

The solution is currently serving thousands of transaction per second, while its capacity can be easily scaled at any time, which was one of our requirements that Logate has fulfilled.”

Supporting multiple access technologies on a single AAA platform

In 2018. Hrvatski Telekom sought for a vendor to replace their old AAA (RADIUS) system for fixed users and to build a test AAA system, and to extend their NFVI infrastructure. Based on the extensive experience, Logate was chosen as a provider. After successful completion of the project, the cooperation continued on the project of extending the AAA platform to support mobile users and VoWiFi. Logate managed to introduce an efficient, scalable and stable virtual AAA system that was capable to support services offered by the client in a virtual environment and across several data centers.

The capabilities of OpenProvider AAA were especially distinguishable when the system was required to handle a growing number of users and user transactions that Hrvatski Telekom ex- perienced, especially in the domain of mobile services, for which Hrvatski Telekom is known to be a leader in the Croatian market.

The system was implemented on 3 data centers, all working in the active-active load sharing mode.

The collaboration history and challenge - Crnogorski Telekom and Logate

Crnogorski Telekom is the company where Logate initially developed its OpenProvider AAA platform, in 1998, in C language, to serve the needs of the dial-up and ADSL services at that

time. As the services evolved so has the platform. In 2009. its internal architecture was completely changed with the introduction of Service Management Engine (SME) and Open Function, which simplified product configuration and runtime modification. In 2009. OpenProvider was already protocol and vendor agnostic. From the start, the platform was also designed to run in a virtual environment.

In 2012. the system was further upgraded by replacing the underlying RADIUS server with

FreeRADIUS server for protocol related functions and OpenProvider Policing engine for implementing business and policy rules, subscriber and session management. In this version

OpenProvider includes EAP with all subtypes integrated. This version also included Transparent Auto Login (TAL) functionality and extended RADIUS Proxy policing with Forwarding Authorization, Accounting, CoA and PoD packets.

Finally, the product was upgraded once more as vAAA version (VNF) that was developed in

accordance with ISG NFV ETSI standards and 3GPP standards. Designed to be deployed on

Telco Cloud environment (virtualized infrastructure) where TOSCA MANO orchestrator is

present. It was released in 2017 and maintained and upgraded since.

OpenProvider and IP services in Crnogorski Telekom

Since the early days of Crnogorski Telekom in Montenegro, Logate developed OpenProvider AAA from scratch to meet the developing needs of the Montenegrin telecommunications market. Through more than 10 years of serving Crnogorski Telekom, Logate was able to deliver various complete solutions that included:

  • IP Policy, charging control and subscriber data management for Broadband, Mobile and WiFi users.
  • 100+ services including Dial-up, ADSL, VDSL, Optics and WiFi services for over 250,000 subscribers
  • Captive portal for WiFi authorization and Captive services
  • 3GPP AAA for 3G/4G mobile users on public and private APNs
  • Hybrid access (fixed and mobile convergence) project

Logate is still the main partner and vendor to Crnogorski Telekom in the domain of mainte nance and improvements of the AAA infrastructure, helping the client to constantly bring innovative services to the market (e.g. VoWiFi).
