Amdocs Network Research: VoLTE Call Drops Are 4-5 Times Higher Than 2G/3G Calls
February 04 2016 - 6:00AM
Amdocs (Nasdaq:DOX), the leading provider of customer experience
solutions, today released new research highlighting the need for
operators to consider optimizing their radio access networks (RAN).
This will enable operators to contend with the annual doubling of
demand for data, increased network complexity, the increased demand
for video viewing on smartphones and tablets, and the initial
instability of new services being introduced such as voice over LTE
(VoLTE). The research 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.
Key findings include:
- VoLTE call drops can be four to five times higher than
calls on 2G or 3G networks: VoLTE is an important and
strategic service for operators as it offers operating expense
(OPEX) and capital expense (CAPEX) reductions through the promise
of repurposing 2G and 3G services. However, this study suggests
that the quality of experience VoLTE provides initially,
post-deployment, can be less stable than the traditional voice
service it replaces, requiring aggressive tuning by the
operator.
- Network data demand is increasing every year:
Research suggests that the volume of mobile data usage is growing
across the world at approximately 60 percent year-on-year1,
particularly with increased demand for video on devices providing
better entertainment opportunities to mobile users. However, 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, the study
highlights that service providers need to offload more traffic from
cellular networks to Wi-Fi networks, in order to realize greater
cost and operational efficiencies.
- Seventy-five percent of network traffic in cities is
in-building: In times of network congestion, indoor users
face up to a 25 percent increase in network issues compared to
outdoors users. By understanding and visualizing the real-world
patterns of demand, coverage and congestion, operators could
effectively target network optimization efforts at these problem
areas to deliver a consistent, quality of network
experience.
- Music and sport events create their own mobile
ecosystems: 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. Therefore, 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 for example. This indicates there is considerable
communication with fellow event attendees while going to the venue
through email, text and social media. Meanwhile, it was also seen
that international roamers upload almost 50 percent more data while
at events than non-roamers.
- International roamers suffer poorer network
experience: Despite the fact that international roamers
can offer operators greater revenues than a corresponding
locally-based subscriber, their network experience can be up to 25
percent worse. There is an opportunity for operators to realize
greater monetization of services by isolating profitable
international roamers, understanding their distinct usage patterns,
and optimizing the network to better target them.
“The Amdocs State of the RAN research reinforces the sheer
strain mobile networks are under,” said Ann Hatchell, head of
network marketing at Amdocs. “In The New World of Customer
Experience, service providers need to deliver a first-class network
experience when and where it matters most. By leveraging the power
of RAN software, service providers gain operational efficiencies
and improved service agility with a centralized vendor-neutral
approach. This allows them to optimize quality of experience, even
under times of network congestion, and build better relationships
with high value customers.”
