2. Network Optimization Activities
The following activities have been taken during the network optimization of mentioned area:
• Physical Verification of Sites for any discrepancies in implementation versus planning data.
• Parameter consistency checks and implementation of Change Requests if required.
• Detailed drive tests for various service types to verify the network performance in terms of received signal level, call quality, call setup, handovers (Intra-Frequency & IRAT), and call drops.Refer to drive plots and statistics.
• Coverage optimization by means of physical changes at site. Page 3 of 21

• Neighbor Relations – Added & Deleted during optimization (IRAT & INTRA)
• Pilot Pollution optimization by means of physical changes at site.

Type of Calls:Mobility Test: MS1 Scanner
UMTS Scanner would be used continuously to monitor RF condition for CPICH RSCP, CPICH Ec/No, Scrambling Code, etc.
Mobility Test: UE1 HSDPAFor data collection of HSDPA data call UE1 mobile will be used to down load (FTP) heavy file of data from FTP Server. This UE will be locked to 3G.
Mobility Test: UE2 PS CallFor data collection of PS R99 data call UE2 mobile will be used to down load (FTP) 20 MBytes of data from FTP Server. This is will be in dual mode.
Mobility Test: UE3 Voice CallThe duration of the calls on UE 4 will be ninety (90) seconds and the idle period between two calls will be 30 seconds to allow reselection.
Mobility Test: UE4 Voice CallThe duration of the calls on UE 3 will be ninety (90) seconds and the idle period between two calls will be 10 seconds to allow reselection.
