Advanced Calling & Messaging

Communication experiences beyond voice and SMS

What is Advanced Communications ?

Advanced Communications refers to calls and messages that have enhanced features delivering a new fluid communications experience, beyond voice and SMS. It provides consumers with instant messaging or chat, live video and file sharing across devices on any network.

Advanced communications marks the transition of messaging and voice capabilities from Circuit Switched technology to an all-IP world. It shares the same IMS investment and leverages the same IMS capabilities as VoLTE and video calls over LTE.

Who is this valuable for?

What are the benefits of  Advanced Communications?

Advanced calling and messaging services:

  • Keeps consumers connected;
  • Ensures operators’ services retain relevance for consumers;
  • Offers consumers competitive solutions with alternative apps;
  • Delivers the messaging service step-change the consumer is seeking;
  • Enables the continuation of operator-centric messaging services;
  • Enhances the call experience with innovative service offerings;
  • Protects the revenue streams that operators are still receiving from voice services;
  • Builds upon the unique operator propositions of: ubiquity, global interoperability, service assurance, security and privacy management and trust as a service provider;
  • Offers an opportunity to expand core products and services;
  • Is a route to developing more targeted, engaging customer propositions, e.g. via chat-based games, mobile learning, smart ads and promotions;
  • Drives stickiness and revenue;
  • Is a route to getting a return on IMS investment from the start (by enabling operators to generate new revenue streams through the creation of apps and B2B services); and
  • Enables operators to quickly deploy RCS as a stand-alone set of services in advance of LTE, VoLTE and HD voice services. Operators benefit from “pay as you grow” costs, without the need to buy and install IMS equipment.
