The second edition of the VoLTE conference will take place at the Novotel Convention Paris Roissy CDG from 10 to 12 October, 2012.
The 2011 edition covered CSFB and VoLTE deployment issues together with security aspects. Experts addressed architecture & protocols, services, VoLTE solutions descriptions, capacity and deployment issues and VoLTE building blocks.
The success of this first edition proved that VoLTE is definitely a killer application that would assure the success of the next coming LTE services.
However a lot of technical issues remain to be solved. Indeed, being an all-IP network architecture designed for data, LTE does not yet adequately support legacy circuit-switch (CS) domain services, which is a problem insofar as these applications account for more than 80 percent of global mobile service revenues, and may be more profitable than data.
Analysts claim that the availability of standardized voice will help LTE take off more quickly. Voice over LTE is completely IP-based and uses SIP (Session Initiation Protocol) to set up the call. It works like a regular phone call, but for the industry it is an important step.

IMS for First-class VoLTE
Moreover, circuit-switch fallback and dual-radio devices will serve as useful interim mechanisms for some operators in the context of a ten-year LTE planning horizon, making the transition to IMS-based call control achievable.
This way, operators can introduce VoLTE without having to fully implement IMS, and then evolve the network over time as end-user requirements and demand for rich media become clearer and as technology matures. Similarly, handset makers can create devices that support 3GPP Release 8 and Release 9 functions that work with a VoLTE network and are also prepared for network and service evolution
However IMS provides a framework and is only the starting point for VoLTE. The industry needs requirements to deliver trusted, first-class VoLTE and multimedia communications over all broadband networks—fixed and mobile.
These requirements include security issues at all borders – LTE, Internet and interconnect, IMS realization options, interworking requirements to accelerate time to market, 3G hand-off for voice continuity and, finally, quality and cost controls to maximize experience and profitability- Which VoLTE standard will be implemented?
- Will VoLTE match the service capability of the existing circuit-switched domain used in 2G and 3G networks?
- What role will IMS play in the VoLTE roll-outs?
- What is the role of multiple PDNs and dedicated bearers in voice scenarios?
- Which fixed-line services are easy to migrate to VoLTE?
- What are the voice features for the near future?
Responses will be given during the VoLTE conference to be held in Novotel Convention Paris Roissy CDG from 10 to 12 October 2012. |
