    Test Result for (Sector 3 PCI 9)

    Comment:

    1. For interworking test only Sector 3 (PCI 9) was active. All other sectors of was de-activated. remained

    active but the active cells did not interfere with the tests.

    2. The drive route as shown in the next slide. We drove repeatedly between Point A to Point B.

    3. The point of 3G-4G interworking happens in vicinity of Point A and Point B.

    4. TC4 and TC5 were re-tested on 14/7/2012. The previous test cases were discarded due to missing 3G

    messages and data collection errors.

    5. For TC5, there is a longer interruption time of 8.99 sec (compared to about 7 sec) in the case of 4GHW re-directing to 3G NSN. This longer interruption time is due to cell reselections in 3G area, from

    SC 15 to SC 377.
