The Big Picture Optimization Issues CDMA 1xRTT

1xRTT services may include both traditional circuit-switched voice and new fast IP data connections

• A User's link is in multiple jeopardy, both radio and packet worlds

Radio environment portion

• Problems: FER, drops, access failures, capacity woes
• Causes: mainly in the RF world, because of mainly RF problems
  

Packet environment

• Problems: Setup failures, dropped connections, low throughput
• Causes: could be IP-related, or could be RF related
  

Optimization Issues
Network Design and Configuration

• Coverage holes, excessive coverage overlap

Call Processing Problems due to Misconfiguration

• Neighbor Lists
• Search Windows
• Power control parameters
  

Physical Problems/Hardware Problems

• Mismatched multicarrier sector coverage

Capacity Issues

• Forward and Reverse Power Control Overload
• Physical resource congestion : Channel elements, packet pipes - IP network congestion
  

Managing A New Dimension: circuit-switched and IP traffic blend

• QoS-related competitive issues
