LTE data roaming is currently one
of the major challenges for telecommunication operators. With
increased demand for high-speed data consumption abroad from
the end-customer’s side, LTE data roaming is the
next step for providers.
LTE roaming on an IPX basis will be a
major driver for the global signalling market. The total number
of signalling messages for roaming is expected to grow by more
than 150% by 2016. Data volumes generated by LTE will also show a strong upward trend,
increasing by 92% per year until 2015. This development will be
mainly driven by Asia and Europe.
In order to support high-speed internet surfing beyond their
borders, network providers need to put in place a
high-performance roaming infrastructure, in addition to
establishing a contractual base with their counterparts. This
involves the exchange of signalling messages as well as the
transport of the data (payload).
How to choose the best possible solution for LTE data
In this regard, operators need to make a strategic decision on
their approach to signalling and data transport. But which
solution is the most suitable one? What are the economic
drivers of each one? How can we achieve a fast time-to-market?
We asked ourselves the same questions concerning data roaming
for the Telekom Austria Group, which has retail subsidiaries in
eight countries in CEE and with more than 20 million
end-customers in the mobile communication segment.
Direct peerings are one way to connect with other MNOs, often
ending up with a meshed-up network that proves quite costly. If
you only want to offer LTE data roaming in a few neighbouring
countries, direct peerings might nevertheless be appropriate
However, not every provider can rely on a proprietary
international signalling network. In many cases, telecom
companies outsource these services to specialised providers. If
you want to offer your end customers global connectivity, an
international carrier’s IPX and LTE signalling
service might be an interesting offer to consider, since you
only need to set up and calculate for the connection to this
