VoLTE call drops can be four to five times higher than calls on 2G or 3G networks, said a research by Amdocs.
The quality of VoLTE can be less stable than the traditional voice service by 2G and 3G.
The telecom report said there is a need for telecom operators to consider optimizing their radio access networks (RAN). The research on VoLTE is based on analysis of more than 25 million voice and data connections from 80 different network operators around the world in the past 12 months.
The volume of mobile data usage is growing at approximately 60 percent year-on-year. With only 5 to 15 percent of Wi-Fi traffic going through mobile devices that is able to be accurately described as Wi-Fi offload, service providers need to offload more traffic from cellular networks to Wi-Fi networks.
During network congestion, indoor users face up to 25 percent increase in network issues compared to outdoors users. Telecom operators could effectively target network optimization efforts at these problem areas to deliver a consistent, quality of network experience.
SMS is still the killer app with an average of 70 percent of attendees at a concert or sporting event sending at least one text message during it, which causes spikes in network usage. There is a need to manage network capacity during an event, with network cells around an event’s location carrying approximately 50 percent more traffic than the cells inside a stadium. International roamers upload almost 50 percent more data while at events than non-roamers.
Despite the fact that international roamers can offer telecom operators greater revenues than a corresponding locally-based subscriber, their network experience can be up to 25 percent worse.
Ann Hatchell, head of network marketing at Amdocs, said: “By leveraging the RAN software, service providers gain operational efficiencies and improved service agility with a centralized vendor-neutral approach. This allows telecom to optimize quality of experience, even under times of network congestion.”
