More Challenge to Critical Communication
and Standardization
• Administration System
• National + Provincial
• Coordination with other government department, such as transport ,
power
Network and Technology
• Network: Public or Private?
• Technology: Telecommunication or Internet?
Standard Support

Challenges & hot Issues
 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

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.
