Friday, July 10, 2020, Santiago, Chile – In keeping with current network demands, Chilean mobile operator WOM has partnered with digital enablement and revenue management software provider Alepo to enter the fixed broadband (FTTH) market. Alepo’s AAA for broadband will help the operator introduce uninterrupted high-speed data services with 24×7 remote customer support, online payments, and a customer-first approach.

Set for a July 2020 launch, the project will be an entirely remote implementation to work around ongoing COVID-19-related travel restrictions. Alepo will partner with a local hardware system integrator for the installation of new servers with virtual environments on geo-redundant sites that the AAA applications will run on.

Alepo’s stateless AAA server is highly scalable and will help WOM monetize network usage through a flexible policy framework. Alepo’s AAA will offer WOM the ability to launch postpaid and prepaid unlimited data plans with speeds up to 1 Gbps, as well as limited data and fair usage packages. Customers will be redirected to Alepo’s digital portal to renew their plans or pay past dues, completely automating their experience and reducing calls to customer care.

Implementation of the AAA will provide WOM with zero revenue leakage, accurate usage-based billing, and usage reports that help monitor subscriber data consumption patterns to quickly adapt through a centralized configuration manager.

With this project, WOM expects to acquire over 500k subscribers within the first year and eventually build up to 1.5M subscribers by the end of 2023.

“We are pleased to partner with Alepo given its history of delivering innovative and award-winning digital broadband solutions to service providers around the globe. With the shift to working from home and social distancing, there has been unprecedented demand for broadband networks. We are confident that Alepo’s AAA will help us alleviate this load with the introduction of ultrafast services. Its monetization capabilities will help us drive ROI while ensuring customer satisfaction,” said Christopher Adam Laska, CEO, WOM.

Juan Espinosa, Director LATAM Alepo, said, “Alepo’s AAA will create greater data monetization opportunities for WOM by facilitating data usage reporting and providing new billing capabilities, while simultaneously minimizing service activation and delivery costs. Our robust and scalable solution will help WOM increase customer satisfaction with higher data speeds and expand its broadband presence rapidly in Chile.”

About WOM

WOM, meaning ’word of mouth’ in Spanish, was launched in July 2015, after the purchase of the old telecommunications company Nextel Chile. According to official statistics, as of March 2019, WOM had 4,120,000 clients. They offer 4G voice services as well as Voice WiFi that facilitates users to make and receive calls through any WiFi network in the world that offers an internet connection, regardless of whether or not the WOM client is in the operator’s coverage area. This is ideal for use abroad and avoids expensive international roaming. The Voice 4G and Voice WiFi services were made available to all the company’s customers (prepaid and postpaid) from December 13, 2018, thus becoming the first telecommunications company in Chile to implement such services nationwide.

How to tackle NFV AAA deployment challenges

How to tackle NFV AAA deployment challenges

12th of June 2020

Network Function Virtualization (NFV) helps service providers transform deployment and operational processes. The maturing of NFV means that AAA can now be deployed virtually – a game-changer that optimizes resource utilization and network operations. From our experience in deploying virtualized AAA (vAAA), we’ve noticed there are some frequently occurring challenges. The good news is, we’ve also identified how to address them.

First things first: the most important thing about NFV

Conventional hardware infrastructure deployments mean the installation of application-specific servers or appliances on the customer’s premises. Network Function Virtualization (NFV) technology introduces a well-defined cloud architecture that eliminates the bind between application and physical server by virtualizing network services. Deploying virtualized network functions (VNFs) reduces the need to maintain vendor-specific or customized physical infrastructure. Applications can now be deployed on standardized and shared infrastructure, significantly reducing operational costs and making it faster to implement.

What objectives do NFV-based deployments meet?

Important outcomes that make NFV software-defined networking (NFV SDN) increasingly valuable include reduced complexity of networks, faster services, and lowered dependence on expensive physical storage. Further, NFV-based deployments aim to maintain a standard-based infrastructure shared by all VNF vendors, keeping OPEX and CAPEX low. Its core objectives include:

Efficiency

The NFV platform must have availability-adjusted NF SLAs that are identical to SLAs offered with dedicated services, specifying, for instance, the average delay, bandwidth, and availability of all services provided to the subscribers. To ensure SLA compliance, it needs to closely track network performance and dynamically adjust resources.

Scalability

The NFV platform should support a large number of VNFs and scale as traffic volumes and application usage increase. The ability to deliver a variety of NFs per subscriber could lead to the creation of new services, opening new ways for operators to monetize their networks.

Reliability

The NFV platform must comply with reliability requirements to offer high service availability, which is defined as end-to-end service availability including end-to-end service elements (VNF and infrastructure components).

How to overcome challenges in NFV AAA (vAAA) deployments

Let’s take a look at the top six NFV implementation challenges and the ideal solutions we’ve developed to address them.

Challenge	Solution
Configuration management Managing file-based configurations for AAA nodes becomes complex and error-prone when each AAA node runs with its own copy of the configuration and requires syncing as nodes are dynamically added or removed.	Centralized configuration management This helps manage the configuration changes (scripts or license files) through a web-based configuration portal, allowing changes to every AAA node in real-time. Alternatively, all configurations can be held in a centralized configuration database.
Lack of compatibility for VNF management interfaces Many NFV infrastructure (NFVi) vendors require a custom interface for VNF management than standard-based, making them incompatible with other vendors.	Flexible VNF management Selecting AAA vendors that offer flexible VNF management interfaces based on ETSI-compatible interfaces or custom interfaces based on NFVi instances is ideal to expedite deployment.
Vendor-specific user access management systems Different vendors have their own access management system for their applications. This adds to operational overheads as user logins and access permissions are maintained in multiple systems.	Centralized access management A centralized user access management system for all vendor applications eases operations, improves control over access controllers, and enhances application security.
Impact of session cache synchronization In NFV deployment, each AAA node is dynamically added or removed based on traffic needs. This requires each node to replicate the session cache to other nodes, increasing complexity and introducing errors.	Stateless AAA It is important to externalize application states and stores session contexts in a centralized database that can be shared across all AAA nodes. A stateless AAA ensures any node can process an ongoing user session request previously handled by another node and that simplifies dynamic scaling without having to worry about session cache synchronization.
Low variety of load balancers For virtualized AAA deployment, load balancers are needed to distribute signaling traffic across multiple AAA nodes. In the NFVi environment, very few software-based load balancers support RADIUS/UDP messages.	In-built load balancer Software-based load balancer VNFs are part of new-generation vAAA solutions and this helps implement RADIUS/UDP as well as HTTP traffic load-balancing.
Common network interface for all network traffic AAA deployed with a common network interface for handling applications and database traffic leads to security concerns and also prevents resource optimization based on traffic type.	Multiple networks for different traffic Separate network interfaces address key security challenges and optimize network resources. Each AAA node has multiple virtual network interfaces to handle different data traffic, applications, and database, making it more secure and scalable.

Conclusion

NFV reduces dependence on dedicated infrastructure. As a result, a vAAA solution enables significant customization and scalability that cuts across the operator’s entire network framework. Operators can, therefore, earn additional revenue without investing in any new hardware.

One of just a handful in the market, Alepo’s NFV- and 5G-compliant virtualized AAA (vAAA) can be deployed in any NFVi environment according to ETSI standards. Manage the entire AAA VNF life cycle with Alepo using its specific Virtual Network Function (sVNF), or integrate with a generic Virtual Network Function (gVNF) from any NFVi vendor. The carrier-grade 3GPP AAA is designed to optimize mobile, WiFi, and fixed network performance. Equipped with a proven and scalable integration framework, it optimizes scalability and resource utilization through orchestration. It can be rapidly deployed and offers quick insights into the way IP data services are accessed and consumed.
