Evolution of voice Communication

The telecom landscape has evolved, as far as infrastructure, services and contents are concerned. Industry  is  witnessing a  migration from  Legacy to  NGN.  Next Generation  Network  (NGN)  is  being implemented globally as a means to change the cost base, agility and service capabilities of telecoms providers. The evolved architecture for the transition is one that provides flexibility to service providers by enabling them to deploy new services on IP based technologies, while leveraging existing services and infrastructure as long as it makes sense.

This post describes the evolution of voice communication in access ,transport and  session layers respectively.

Business Challenges for a telecom service provider

With the fast pace of telecom evolution both towards the access network front ( ie GSM , UMTS , 3G , 4G , LTE , VOLTE ) to core network side ( ie application servers , registrar , proxies , gateway , media server etc ) a CSP ( content service provider ) is trying hard to keep up with the user expectation . The user expects a plethora of services , reduced cost and high speed bandwidth . If this was not enough a CSP also has competition  OTT (   Over The Top ) Players who provide communication and messaging for FREE .

You can read on how OTT’s players are disruption the revenue streams of traditional telecom operators and how can Telco’s develop  their own OTT app , integrated with their backend system to answer to that challenge  here – OTT ( Over the Top ) Communication applications

The following points outline the major business challenges faced by telecom operators today .

Technology Evolution Challenges

  •  The increased data speeds and further more increasing hunger for the data overwhelms the existing network infrastructures.
  • Ensure uniform service experience across the network technologies to check the customer churn.
  • Access / Radio Technology independent delivery of services.
  • Enhance Reuse for exiting investments.

Multiple Service Platform Challenges

  • Typical network constitutes of Multiple Service Platforms increasing network complexity and integration challenges many fold.
  • Heterogeneous multiple SDP Solutions typically deployed to cater to Multiple Types of Networks/ Standards/Variants
  • Service Islands makes introduction of seamless services a challenging task for the CSP

Transport Upgrade and Convergence of Wireless Wireline

  • Retain investments in copper wire systems while migrating towards next generation Fiber Optic systems.
  • Severe competition among wire-line and wireless operators to provide latest services to retain subscriber base.
  • Fixed Mobile Convergence leading to a diminishing gap among the revenue shares of various operators in the space, and leading to losses for wire-line only players.
