INTRODUCTION GPEH is a Performance Recording function which consists of two types of recording, User Equipment Traffic Recording (UETR) and Cell Traffic Recording (CTR) that supports Ericsson network. Xeus helps you to analyze calls, events, cells or phone models using GPEH data. It currently supports only Ericsson WCDMA network. Refer to Appendix 1 for Ericsson GPEH Recording Steps.

LIMITING THE GPEH DATA COLLECTION Depending on the analysis type to be performed in Xeus, user can limit the GPEH Event type to be collected in GPEH in order to reduce RNC processor load for recording. RNC has a parameter gpehDataLevel that determines the level of information to record for the external protocol such as RRC and RANAP.

The default setting of the parameter is 0 = 'HEADER_DATA_ONLY', which records only the external protocol message name and direction of the message. In order to record the encoded ASN.1 data of the external message, the OSS administrator can set the parameter to 1 = ‘ALL DATA’. This will allow detail analysis of the external protocol message. However, this is only recommended for small recording set of cells to avoid overloading the RNC processor or the GPEH data file limit. Refer to Appendix 1 for steps on how to configure the GPEH collection parameter at the RNC.

Following are the features in Xeus which requires gpehDataLevel set to 1 = ‘ALL DATA’:

• IMEI info for Phone Profiling

• Message detail for external protocol

• NAS Messages in the RRC Direct Transfer messages

• Active Set Measurement which include monitored set from RRC Measurement Report

• Call Setup Analysis drill down of Blocked Call Analysis

• Call Type categorization from the RRC Connection Request

• Call Drop categorization from RANAP IU RELEASE and RRC Connection Release messages

SUPPORTED FORMAT AND LOG FILE DATA Xeus supports GPEH/UETR/CTR log file formats such as .bin and .bin.gz. They are usually grouped in sets and each set contains a reference file. The reference file contains links to other files in the set. It is mandatory to import the reference file for the set. The reference file usually contains ‘0’ as part of its name. Refer to the picture below as a guide:

Each set of log file data should contain the messages in Table 1 above.

Rev 11


GEOANALYSIS OVERVIEW AND PREREQUISITES GeoAnalysis is a new feature on Xeus which enables you to estimate a location using non‐GPS based Network Measurement Recordings. Xeus uses GeoAnalysis to perform Geo‐locate using a combination of OTDDA multi lateration and relative signal strength. Analysis on GeoAnalysis is done through plots and reporting. Using GeoAnalysis, geo‐located events and measurements can be plotted and areas where significant pilot overlaps identified.

Before performing GeoAnalysis, ensure that you have the supported network data that meets the following prerequisites:

1. The network data imported must be either Ericsson Bulk CM or Ericsson Kget log file. The imported Network data must contain the RNC and Cell that matches with the data recorded in GPEH.

Note: For best analysis or Geo‐locate through GeoAnalysis, it is recommended for you to import the network data that takes at least an hour to parse.

2. The GPEH recording must contain RRC Measurement Report and NBAP Radio Link Setup Request messages.

3. Ensure that ‘Perform position estimation for Abnormal Released Calls/All Calls’ is enabled at ‘Import Ericsson GPEH/UETR/CTR log’ wizard.

IMPORT GPEH/UETR/CTR LOG FILES You need to ensure that you have the following data before you import GPEH/UETR/CTR data:

1. Network data (preferably Ericsson Bulk CM). 1.1. Network Data accepted for GeoAnalysis (Ericsson Bulk CM or Ericsson Kget log file only)

2. log file format 3. log file set(s) contain mandatory messages GPEH/UETR/CTR data is best analyzed when you have Ericsson Bulk CM. It will provide complete analysis for neighbor optimization. If you are performing GeoAnalysis, ensure that the network data selected is Ericsson Bulk CM or Ericsson Kget log file. You can refer to Xeus Pro Quick Guide for further information on importing network data.
