The future is here
…and IP is at the centre of it. The strategic importance of IP-based solutions is clear; having all-IP based infrastructure and services enables operators to deliver a broader, deeper communications portfolio – incorporating voice, data, video and other rich communication services.
Embracing the all-IP future solution is vital for operators if they are to retain customer relevance and have a network capable of meeting the ever-growing customer demand for data services and ever-richer communications.
What is the GSMA doing to help?
The GSMA’s Network 2020 programme is designed to help operators make IP Communications work as a native service behind the ‘Green Button Promise’. It aims to address and navigate the complexities of progression to an all-IP communications network. The first phase of the programme focuses on two main areas – ensuring devices and networks can deliver a native experience and that VoLTE and RCS interoperable solutions are established.
What is the ‘Green Button Promise’?
Operators can offer a unique, rich IP-based communications proposition to their customers. This means providing RCS voice and messaging, video-based calling and VoLTE calls – all with the same telecoms grade experience historically linked only with voice services. The ‘Green Button Promise’ sums up this proposition, reflecting the previous experience of using a green button on a device to initiate a voice call.
In practice, the ‘Green Button Promise’ means customers get reach, reliability and richness. Reach through interconnection to mobile phones and devices globally; quality and reliable services delivered within a trusted ecosystem with privacy and security, and richness from the wide range of IP-based operator services:
The ‘green button’ is typically the one users press to make a voice call, and it is associated with a high level of quality and interoperability. It will be a fundamental requirement to embed these principles – the ‘Green Button Promise’ – in all IP-based operator services:
- Voice calling – IR92 Voice over LTE (VoLTE) and HD Voice
- Rich Communication Services (RCS) – Voice, Video Calling and Messaging
- Video calls – IR94 Video over LTE
Achieving this will fulfil customers’ expectations that services initiated via the calling or messaging buttons will be high quality and fully interoperable, regardless of network.
Individual elements of the Network 2020 programme will focus on helping networks deploy Voice over Long Term Evolution (VoLTE) and Video calls over LTE utilising IMS technology. In addition, the programme will continue to encourage the RCS Ecosystem to help operators prepare for and launch RCS-based interoperable rich communication solutions for their customers around the world.
Quality based Interoperability
Users of operator IP services e.g. Voice or Video calls over LTE, will expect a quality service, wherever, whenever, and on whatever device. Quality of Service (QoS) will underpin the delivery of the ‘Green Button promise’. A unique capability for operators as well as a potential differentiation asset, QoS offers new business opportunities to explore with other Service / Content Providers.
The Network 2020 programme will work with operators to determine the technical and commercial specifications for operator-to-operator QoS for IP Services, and encourage them to incorporate the QoS philosophy into their customer solutions.
A further programme objective is to help catalyse commercial implementations for IP Interconnect solutions between operators and Service / Content providers.
