1.1 Google earth Map showing the Site location

A drive test was performed to verify and validate the site integration for “site name”

The drive was done within the circle area as shown in the map below.

1.4 Test procedures

TEST CASES DRIVE TEST METHODOLOGY

Coverage and quality performance check

The Rx level of each sector will be checked by locking on the BCCH in idle mode.

The Rx quality for each sector will be checked by locking on the BCCH in dedicated mode.

A drive test around the site will be done to check the coverage distribution of the site where there is accessible road. This will help to check the cross feeder connection.

Call Performance Check.

Set call model parameters: Destination Number = 118, Originate Mode = GSM, Call Type = Call by Call, Setup Timeout = 30s, Call Duration = 120s, Test/Exceptional Interval = 15s, Call Start Mode = Idle Mode, Call times = 5 times

Handover Performance CheckHandover performance to be verified by locking on the BCCH and then forcing the call to handover to the target cell.

3 Site Performance Test

3.1 Accessibility and Retainability: SHC test

Site acceptance performance test should be performed in static mode and in

good RF conditions, Rx level > -75dBm & C/I> 12dB,

3.2 Handover Test

Handover tests will be performed to demonstrate the mobility feature

supported by the network.

For isolated sites, if there is no continuous coverage, the inter-site handover

test will be ignored (discarded)

3.3 Throughput performance

Site acceptance performance test should be performed in static mode and in

good RF conditions, Rx level > -75dBm & C/I> 12dB.

3.3.1 EDGE Uplink and Downlink throughput performance

App Throughput EDGE_Sec1_1800_DL

App Throughput EDGE_Sec3_1800_UL

Note: Both UL and DL tests are not expected to be done for each sector. The

upload and download test will be done to different sectors of the site to show the

area under the sector is provided with EDGE services regardless of the band.

Test Protocol:

The data transfer will be from a test FTP server. Attempt to download a

specific zip-file (2MB for downlink and 0.5MB for uplink).

FTP server to be provided by Ethio-telecom

Server information:

Ftp:// Address

User name & password

File sizes:

Uplink: 500KB

Downlink: 2MB

4 Acceptance Criteria

All calls, handovers and PS transfer tests should have 100% Success rate. Moreover

all tests should not experience Call drops and PS transfer drops.

Average FTP UL throughput, normally, should not be less than 30 kbps. Average

FTP DL throughput, normally, should not be less than 60 kbps. In case the testing

result is lower than threshold, due to some reasons such as PS user congestion and

so on, the report can be validated after Ericsson provides clarification such as OSS

PS performance data.

The Coverage and Quality requirements is met when the testing mobile station

records an Rx Level full value greater than -65dBm in idle mode and an Rx Quality

sub value of less than 3 in a dedicated mode while testing near to the site under the

sectors main beam coverage.
