Table 1: Test information
2. Purpose of the test
In order to check the network quality status of the existing network before swap, we have
finished one DT work in Phase-1 Cluster-11 to collect the coverage, CESR & Dropped
Call information, as a reference for the Swap benchmark KPI. The two tests will be done
under the same test equipment’s including PC, test mobile, call manner, test route and so on.
3. Test manner instruction
Test software: TEMS Investigation 10.0.5
Test PC: Lenovo
Test mobile: W995
Extra antenna: External antennas (0 gains) mounted on car roof
Max car speed: 40 km/hr
Avg. Car speed: 30 km/hr
SIM card information: GP SIM card (1st) IMSI: 470010030152429;
GP SIM card (2nd) IMSI: 470010030152427;
GP SIM card (3rd) IMSI: 470010030152421;
GP SIM card (4th) IMSI: 470010030152428;
GP SIM card (5th) IMSI: 470010550393471;
GP SIM card (6th) IMSI: 470010550393463;
Call manner:
MS 1 is for long call
MS 2 is for short call.
MS 3 is for idle mode
MS 4 is for terminating from mobile two (not connected to TEMS).
MS 5 is for MOS (master)
MS 6 is for MOS (slave)

Long call instruction: Call duration = unlimited.
Short call instruction: Call duration = 15s; Call interval: 5s.
Originating number: MS 1 GP SIM card number: 01755502550;
MS 2 GP SIM card number: 01755502548;
MS 5 GP SIM card number: 01755502563;
Terminating number:
Long call terminating number: 444555
Short call terminating number: MS 4 GP SIM card number: 01755502545;
MOS Call terminating number: MS 5 GP SIM card number: 01755502563; (Loop Back)
MS 6 GP SIM card number: 01755502555;
Instruction: All services will be measured under voice call mode and idle mode.
