The E-Plus Group is the third largest mobile network operator in Germany, with just over 20 per cent market share. Ahead of the LTE World Summit, the premier 4G event for the telecoms industry taking place on the 24th-26th June 2013 at the Amsterdam RAI, Netherlands, we speak to Dietmar Kohnenmergen, Master Expert System Architect Network for E-Plus Gruppe about its preparation for launching LTE and the issues around diameter signaling.
What have been the major developments around LTE in your region this year?
For E-Plus Gruppe, the major developments have been an IP RAN rollout and the introduction of EPC and associated testing.
Do you feel the people still need to be educated as to what Diameter signaling is?
The experts are quite familiar with Diameter signalling issues, but the operational teams still need some education.
What are the key issues around Diameter that the industry needs to be aware of?
The primary issues are E-signalling load protection and adaptation to the various needs of the different Diameter flavours.
How can these key issues be solved?
From our perspective the introduction of a Diameter Router Agent is one of the most promising solutions for solving diameter issues.
What are the other technical challenges around LTE that you expect to face in the next 12 months?
The introduction of Circuit-Switched Fall Back (CSFB) with acceptable performance will be a major challenge for us. The other challenge will be the preparation of the BSS systems in time for our LTE launch.
Where are you on VoLTE and RCS? Are these important to your LTE strategy?
VoLTE is in preparation phase, whereas our plans around RCS have not been decided yet. VoLTE is set to play a more important role within our LTE strategy.
