Challenges & hot Issues
GSC-18, 22-23 July 2014, Sophia Antipolis
The balance of Telecommunication network and Mobile Internet Application, such as public warning• Mobile Internet Applications play important role in critical
communication• Free• The citizen like and use• broadcast and used rapidly• Don’t need standard
• Cell Broadcast Service in Telecommunication network• Need investment to the network• Need standard and certification• Need long time
11
Challenges & hot Issues
• The balance of Public benefit service and Market service, such as priority call• Service for small percentage of subscriber(authorities),
but large investment (the whole network)
• Standard is ready, but how to use and implement standard is more important
• How to encourage the operator to update the network ?• The feeling of citizen: unfair? Equal communication right.
