1 Summary

This document is to describe the concept of the site performance acceptance for the

integrated site to check the functionality and site ability.

The objective of this report is to evaluate the performance of the Flexi eNodeB in the LTE

environment with a set of defined Test Cases to be evaluated and achieved.

Prior to the commencement of field testing, there will be an initial period during which all

setups shall be validated. This includes a validation of proper functioning of the field

test elements such as the UEs, Drive Testing Tool and applications. In addition, the

network will be analyzed via measurements to ensure that any radio conditions that

Have been specified as essential for testing are actually being realized.

Following are the system and software versions used while performing the tests:

SW used: RL15, Altair UE 7210, 20 MHz bandwidth UE tracer XCAL/XCAP ,Agilent

Filezilla FTP client.

Performance will be evaluated as follows:

Drive Testing

Data Throughput Testing

Handover

Latency

2 Acceptance Methodology

The Acceptance will be done using the following inputs:

1. Analysis of site performance drive test results as carried out by NSN.

2. Data Throughput Analysis testing FTP from test laptops using XCAL/Agilent.

Site Performance Drive Test results will be used as Final Site Acceptance Criteria.

The Site Performance Drive Test will be performed taking into consideration this site does

not have any alarms.

Proposed Solution

Proposed Solution

3 Drive Testing

Drive Testing (DT) will be used for the following purposes:

1. To check the RF coverage and quality.

2. To ensure functionality testing (intra-eNBHandovers, call drops, etc)

3. To confirm Call processing4. To measure Throughput in DL & UL directions from Application server.

5. To measure latency.

6. To check the RF Configuration of the Site

4 Testing Details

1. Data Throughput

Data Throughput tests will be executed at

Static points under the site.

Coverage Throughput (doing the tests while driving around the sites moving from the

Best Radio Conditions till the Cell Edge )

The following call pattern and cycle will be used:

Attach

Log into the Application Server

FTP,TCP and UDP Download

FTP,TCP and UDP Uplink

Connection release (network detach)

For the Testing duration, For Static Points 1 min continuously is accepted .For Coverage

throughput it is recommended to upload multiple big size files (5-10 GB) before testing

In addition to the aforementioned testing, it is recommended to do 2 multiple sessions

2. Latency

Latency Tests done for

Control Plane (the time required when call setup request start to get the attach

complete )

User Plane (it is the round-trip time when pinging the application server to be tested

with different word size (32,1000 and 1500 Bytes )
