The impact of no-code provisioning automation in small cells deployment

Mobile networks are under increasing pressure. Here some facts:

80% of mobile traffic happens indoor without the need of an external connection.
By 2021, there will be around 11.5 billion mobile devices (1.5x the world population).
Ultra-low latency is required for urgency services and/or autonomous cars.
High throughput demand of symmetric 1Gbps will be the standard.

To comply with these growing demands, distributed virtualized network architectures in mobile networks provide significant scaling advantages and flexible deployment options. An example of this is the use of small cells in fixed broadband access networks to scale the capacity and coverage of mobile networks.

The main purposes for small cells are to:

Improve in-building coverage
Meet growing demands for more capacity (either indoor or outdoor)
Improve the subscriber experience
Build a platform for value-added services

Most cellular operators are now committed to small cell network solutions in one form or another and have them in their business plans.

As wireless networks evolve to 5G and there are limited opportunities to add new spectrum bands and macrocells, small cells will play a critical role in delivering the high bandwidth, densification and low-latency connections required by the myriad potential 5G use cases.

Installing Small Cells Should be as Easy as Installing a Cable Modem

Small cell deployment mainly solves coverage problems for business clients. Nonetheless, it can be used both in business and residential scenarios with any type of Backhaul (DSL, Cable, or Fiber) to treat coverage or capacity issues supporting LTE bands: CBRS 3.5 GHz, LTE-TDD and LTE-FDD licensed bands.

Here we discuss provisioning of small cells, access networks, and virtualized functions, orchestrating through various inventories, network systems, and elements involved in the provisioning automation. We will talk about how the automation and standardization of the small cells provisioning ensure the quality (reducing the manual turn-up/activation issues considerably), speeds up the deployment (allowing operators to reach 10x increase factor without hiring additional staff), and how the automated provisioning and configuration of the virtualized infrastructure and network elements provide network elasticity, expanded coverage and enhances QoE at an attractive cost.

By reducing the dependency on specialized hardware, operators can also expect to lower Capex and Opex while they speed up service delivery, allowing scalability on demand and responding to the network conditions and user needs in real time, opening the way for 5G and dynamic services.

Regarding the complexity of the orchestration, different elements and use cases need to be considered for automation: for management, the HMS / HeMS need to be configured together with the TR-069 ACS and KPI management.

Regarding the Core, the SeGW, HeNB / HeNB GW and Location Function need to be provided. The Core Density, Core Scalability, Transport security, and Multi-vendor small cell management are some additional challenges.

The solution needs to provide simplified management, accelerate time to market and assure ease of integration with the macro network.

The Scenario

5G and IoT are setting high expectations in the customer’s mind, raising the bar for service providers. The business case is centered in augmenting the wireless coverage for billions of connections and providing low latency. The only way to achieve that is by deploying hundreds and even millions of small cells efficiently and on-time.

Assuring that those small cells and backhaul links will meet service level agreements at turn-up presents a new challenge. Traditional manual provisioning and testing methods are simply impractical for current and future needs.

5G is the next-generation mobile networking standard that will build on the global 4G Long Term Evolution (LTE) ecosystem. Its promise goes well beyond high-data rates, spectral efficiency, ultra-low latency, or massive sensor networks. It enables new service opportunities – from just people communicating on phones to fast real-time low latency data transmission between things.

With the landscape of 50B IoT devices connected to the network by 2023 (1), on-demand remote provisioning and management of mobile connectivity is going to be a key factor in catapulting this business to the next level.

According to a Q418 survey of 22 LATAM mobile operators, the top 5
drivers for densification are:

  • Cost-effective way to start 5G deployment in targeted areas
  • Support ‘hot zones’ of high data usage and high revenue potential, e.g smart city, business campus
  • Basis of future IoT and edge-focused services
  • Increased commercial requirement to support indoor cellular e.g. for IoT
  • Lower cost of rural expansion

Key Findings (from Gartner)

The majority of communications service providers (CSPs) now agree that small cells are essential to future cellular networks in order to meet user demands. In countries with a developed cellular infrastructure, most are now implementing small cell strategies to meet both capacity and coverage demands in a cost-effective manner.

Wi-Fi hotspots are an essential part of communication networks, opening up better business plans for mobile virtual network operators (MVNOs) and over-the-top (OTT) players. CSPs are likely to face new competitive trends.
Use of Long Term Evolution (LTE) over unlicensed spectrum opens up new opportunities for cellular operators, and the divide between Wi-Fi and LTE starts to become blurred.

The emergence of small cells has generated new business models and created the need for more partnerships involving CSP equipment vendors, system integrators, and property owners.

Small Cell Deployment Challenges

The current fulfillment and assurance processes in mobile operators were designed for macrocells.

The current fulfillment and assurance processes in mobile operators were designed for macrocells. Those processes limit the deployment of cells to around 10/15 cells per day. To meet a goal of 25,000 or even 100,000 in the spam time needed, operators need to scale to at least 100 cell deployment per day. Adding additional staff (or contractors) is not an option.

The deployment entails complexities such as provision IP backhauls from different access technologies (DOCSIS, GPON, DSL, etc.), support different network equipment vendors (interoperability), and off-net providers with various technologies.

At a higher level, the small cell deployment and turn-up can be summarized in:

  • Deployment preparation
  • Service installation
  • SLA monitoring and maintenance

Small Cells and Virtual EPC

While some cellular operators are still in the planning or trialing stages, others are ramping up their deployments and expanding into new market areas. Small cells can come in several forms:

  • Residential or small or midsize business (SMB) femtocells
  • Indoor or outdoor stand-alone picocells
  • Distributed radio small cells for large locations
  • Carrier-class Wi-Fi hotspots

End-to-end provisioning and management – including a mobile app for field service tasks, devices remote provisioning and firmware management, fault & performance monitoring, dynamic scaling, and self-optimization.

Distributed network architectures are emerging to provide significant scale advantages and flexible deployment options. An example of this is the use of small cell distributed nodes to scale capacity and coverage of cellular networks.

This emerging type of distributed network architecture requires provisioning of the remote infrastructure to onboard new devices (or nodes) and manage them remotely across its lifecycle.

The solution provides orchestration across the various inventories, network, and element management system that are involved in the automation of provisioning. This also assures the quality of installation of new remote devices to the network infrastructure.
