Evolution is part and parcel of a Mobile Network Operator’s strategic and operational plans. It is necessary to stay ahead of competition, innovate to challenge industry disruptors and to maintain profit margins.

Over the last couple of decades, the mobile penetration and usage sophistication have also increased to such an extent, that mobile operators have had to come up with network expansions to meet the rising demands whilst maintaining high QoS(quality of services).If any services had to be scaled, more hardware needs to be purchased, integrated to existing infrastructure and tested end to end to serve the changing capacity demands. However, such a static hardware based infrastructure does not offer the flexibility to shape networks organically.

Value added services have become one of the major revenue generators in the telecom industry. It helps in gaining a competitive advantage for sustaining growth directives. Moreover, VAS

  • Is a key customer engagement framework e.g. customer services applications
  • Creates “stickiness” with customers resulting in reduced churn.
  • Insights can be used as market intelligence to understand user behaviour
  • Maintain Operator brand relevance

 Challenges in VAS domain

Traditional VAS services are typically deployed as silos at both software and hardware levels. This makes introducing new services a time intensive, complex process. Monolithic services restrict collective solution building which adversely affects new service innovations. 

These constraints led to the development of consolidated VAS services which can be deployed on a virtual infrastructure. However some factors, such as scaling to meet changing traffic, still remained unaddressed.

The premise of NFV is to offer flexibility, cost-effectiveness and scalability, all of which can be adopted into the VAS domain to overcome the boundaries of existing service offerings. In order to address these concerns, several Operators formulated the concept of NFV (Network Functions Virtualization) to overcome the challenges in accelerating their turnover and meeting growth objectives.

NFV enabled VAS by Wavenet

Value added services have become one of the major revenue generators in the telecom industry. It helps in gaining a competitive advantage for sustaining growth directives.Value Added Services (VAS) network elements are a logical target for early NFV initiatives.  Virtualizing core network entities introduces many quality and performance considerations while VAS applications are often less critical.

Wavenet’s aim is to deliver solutions that will enable operators to advance with the latest technologies while delivering the best quality services in the most cost effective method. Our expertise in business and technology innovations paved the path of engineering an NFV capable consolidated VAS portfolio which can be deployed on HPE OpenNFV infrastructure. We have leveraged our years of domain experience and Operator requirements to engineer horizontally integrated VAS applications platforms.

Our NFV enabled VAS platforms empower operators to deliver new services faster to the market by allowing on-demand service deployment. The pre-tested VNFs can be easily load-balanced and scaled to meet any specific traffic requirement. The automated process in NFV eliminates time consuming manual provisioning tasks which results in less operational errors and better resource allocation.

Wavenet VNF elasticity allows dynamic service scaling for maximum operational flexibility. This is done in real-time where service continuity and service quality is maintained. By doing so real-time capacity management is achieved to better utilize resources and licences.

Years of domain experience

Many of Wavenet’s customers have been deploying our solutions on virtual servers for several years.  With the arrival of the ETSI NFV ISG specifications we are aligning our products with the life-cycle Management and Orchestration (MANO) framework defined therein. Future versions will be delivered as Virtual Network Functions (VNF) within an NFV environment.  A VNF will represent a cohesively managed cluster of servers offering the same resiliency we do today but cooperating with other VNFs, and physical network functions, within NFV MANO.

Wavenet’s VAS solutions consolidate related applications into one product.Encapsulating “SIGTRAN in a box” is our Prime messaging product, consolidating SMS, SMPP, USSD and MMS applications. The voice and media applications such as RBT, Voicemail, MCA, MCG and IVR are unified in our “SIP in a box” Spark platform. Wavenet Fusion aggregates multi channel service creation into a single visual service creation tool simplifying end to end service provisioning. 

Additionally, Wavenet NFV enabled consolidated platforms have active roadmaps leading towards IMS capability and other emergent technologies

The emergent properties of the consolidated platform such as single point of management, cost savings and optimised resource pooling are amplified when the applications are deployed as VAS VNFs in an NFV environment.
The NFV MANO can intelligently call and assign the resources (VAS VNFs) needed to meet the fluctuating traffic demand.
