Gett Ge ttin in St Star arte ted d wit with h GPEH GPEH Ana Anall si siss in in Xeu Xeuss Pro Pro Overview: Ericsson General Performance Event Handling (GPEH) is a performance recording feature that can perform trace logging function. This feature enables you to utilize the collected GPEH data such as cell information, radio measurements and call messages to perform further analysis on calls, events, cells, phone models & user IMSI.
Pre-requisite for GPEH Analysis: 1. Site Data It is advisable for the user to import the site data by XIF/TEMS Cel-file/ C el-file/ MCOM file format first before the importing of the Ericsson W CDMA OSS Bulk CM XML file or Ericsson RNC MOSHELL KGET log. Table 1 below shows some of the mandatory fields in creating a XIF format site data. Please refer to the Xeus help file found after downloading Xeus into your pc for the full list of XIF format description; XIF Parameter CellId
SiteId Longitude Latitude AntDir RncId
CId
Description The unique Cell Identity/Name of the cell e.g. G1001A. Note: Xeus does not accept two t wo records with SAME Cell Id. Any duplicate ce ll Id will be renamed with additional suffix e.g. G1001A_1. Mandatory field The Site Id of the cell e.g. D1001. Note: Site Id will be displayed as label for cell in the map Longitude of the cell in Float format e.g. -121.23328 . Mandatory field Latitude of the cell in Float format e.g. 30.12312. Mandatory field Direction of the cell in Degree unit Mandatory field RNC Identity Note: RncId-Cid pair allows matching of WCDMA Cell network data to the site data in Xeus database WCDMA Cell Identity Note: RncId-Cid pair allows matching of WCDMA Cell network data to the site data in Xeus database Table 1 – XIF parameter format

2. RNC Network Dump User can import the WCDMA site configuration and neighbor data by the following options 1. Ericsson WCDMA OSS Bulk CM XML file 2. Ericsson RNC MOSHELL KGET log file 3. GPEH Recording Collection Following are the steps to obtain the GPEH recording set. User can look into “Aexio Xeus Pro 2012 GPEH Quick Guide” for a more detail information. GPEH collection parameter settings 1. Start OSS Common Explorer 2. Select the required RNC Node 3. Change the ‘gpehDataLevel’ to ‘ALL_DATA’ 4. Increase the value for ‘gpehFileSize’ parameter to 50,000 (50,000kB) Initiate GPEH Collection 1. Select Performance > Initiate I nitiate data Collection > WCDMA/LTE RAN Measurements 2. Select Administration > Add profile 3. Select GPEH as the subscription profile type 4. Enter profile name 5. Select “RNC network elements should be observed” 6. Select the required RNC for recording 7. Select the required Utran Cells for recording

8. Select the required GPEH recording events. Please check on “Aexio Xeus Pro 2012 GPEH Quick Guide” for the required events on different analysis scenarios. Following table show the recommended GPEH events to be collected for a standard Xeus analysis. GPEH Internal Event

9. Select the UE Fraction for the percentage of mobile that will be recorded. 10. Input the schedule for the profile recording. It is advisable to make sure t here is no others running recording on the planned schedule. 11. Once complete, the collected GPEH files will be located in “/var/opt/ericsson/nms_umts_ “/var/opt/ericsson/nms_umts_pms_seg/seg pms_seg/segment1/GPEH/” ment1/GPEH/” folder.

GPEH Importing: 1. Create a new project 2. Create a complete site data in xif format and import into Xeus. Uncheck “Import Carrier & Neighbor data” as the neighbor data will import by network dump later.
Figure 2 – Import site data in XIF format
3. Import latest Ericsson WCDMA OSS Bulk CM XML or Ericsson RNC MOSHELL KGET log. Uncheck “Import Site Configuration Data” and match cell using “RncId + C id” with previous XIF format of site data.
