Mobile radio access capacity is expensive and scarce

1

• Mobile radio access capacity is expensive and
  scarce
• In trade-off QoS / efficient use of
  capacity network operator will tend to latter
  one (as far as possible)
• Radio access will largely determine end-to-end
  QoS
• Connection rates in e.g. 3rd generation mobile
  will be relatively small ? ideal statistical
  multiplexing in high speed fixed network

2

• Keep fixed network transparent for wireless
  access
• IP Diffserv
• Appropriate overprovisioning
• Timely capacity updates
• MPLS TE
• Challenge design TM rules for above framework
• Which traffic measurements are needed?
• How to exploit these measurements? E.g. triggers
  for capacity update?

3

• TM challenges in 3rd generation mobile
• Radio network planning
• Cell capacity?
• Interference between cells
• Cell breathing
• Radio resource management
• CAC
• takes care that SIR requirements can be met
• statistical multiplexing of interference
• measurement based?
• LSP
• protection of handover calls
• Packet scheduling (QoS differentiation)
• Up- and down link!
