This document describes a cluster drive test for optimizing Long Term Evolution (LTE) networks using the XCAL tool to collect real-time data on various network parameters. The procedure includes performing tests for both data and voice calls to ensure effective handover and minimal interference between cells. Results indicate that the area tested achieves good signal strength and coverage, with satisfactory data transfer speeds for both downlink and uplink operations.

- 1. D Cluster Drive Test of Long Term Evolution using XCAL Fahimuddin khan Abstract—Performance of a mobile communication Long Term Evolution Network depends on how the network is optimized. To optimize such network to deliver services (online gaming, video conferencing, video streaming, downloading, etc.), there is a need of collecting real time data which contains different network paramers details on which the network performance depends. The real time network parameters such as Drive Route, Coverage Plot (overall, sector Alpha, sector Beta, sector Gamma), Mac Layer Throughput Download, Mac Layer Throughput Upload and PCI Plot etc. plays an important role in mobile communication network and the major reason of network performance. To collect real time network parameters details drive test is performed using the drive test tool XCAL. This paper concentrates on the procedure of Cluster drive test and the results obtained after completion of the test. Index Terms— LTE, SINR, PCI, PUSCH, RSRQ, DTDL, DTUL 1 INTRODUCTION rive test is a procedure of collecting real time data which contains mobile communication long term evolution network parameter details. In long term evolution drive test perform two test i.e. single cell function test and cluster drive test. In this paper the details of cluster drive test is given. Cluster test is perform to collect the data of network parameters details of more than one cell. This test is perform when the network is in working state and checking the interference between the two cells as well proper handover take place or not. The details of network parameters such as Drive Route, Coverage Plot (overall, sector Alpha, sector Beta, sector Gamma), Mac Layer Throughput Download, Mac Layer ThroughputUpload, PCI Plot, Quality plots of RSRQ, SINR and PUSCH is collected and with the help of obtained result trying to optimized the long term evolution network to deliver service more efficiently. Cluster test is perform for both voice call and data call testing. One by one both the test perform and collect the real time data of Long Term Evolution network Next, press setting three more fields are to be filled i.e. select Cluster from select type, enter Cluster details for which drive test is performed, select count 1 from cycle option be-cause the test is performed only one time and press save button, 2 PROCEDURE For performing Cluster drive test XCAL tool is used. XCAL is a mobile software installed in a LTE compatible handset and is registered via mobile communication vendor. Step by step procedure is shown below to perform cluster drive test: Press the setting button on the mobile and select FMS (Fleet Management System) mode, and enter the basic details for which the Cluster Test is perform
- 2. Now, select LDL1 and press Start button to perform LDL1test After completing LDL1, there is need to change scenariofrom LDL1 to LDL2 to perform LDL2 test, this test is perform to check for accuracy of LDL1 data transmission down link speed. The purpose of LDL1 and LDL2 are same i.e. to calculate the downlink speed. LDL2 test is perform to cross verifythe LDL1 test. After selecting LDL1, the screen appears below which shows that the GPS value for which the test is perform is locked for testing purpose and File Transfer Protocol (FTP) connection successful to data transfer. It also shows the cur- rent RSRP network values as well as average and current Throughput. After LDL1 test is completed call is automatically stop and there appears queries to complete the test or the test is in progress, here option in progress is to be selected, After selecting LDL2, the screen appears below which shows the details same as LDL1, it also shows the current GPS values where test is performed. After successful completingLDL2 call is automatically stop and there appears queries to complete the test or the test is in progress, here option in progress is to be selected,

After completing LUL, there is need to change scenario from LUL to VoS , the VoS test is perform to test the VoiceCalling After completing LDL2, there is need to change scenario from LDL2 to LUL, the LUL test is perform to test the upload- ing speed, After selecting VoS, the screen appears below which shows the details of voice calling. The screen shows the GPS status, current cluster PCI, SINR value and how many times the call is attempt their success and failure. After collecting all the de tails of VoS call is automatically stop and there appears que- ries to complete the test or the test is in progress, here option in progress is to be selected, After selecting LUL, the screen appears below which shows the details of data uplink. By pressing detail view it also shows the Cluster PCI details of current and surrounding. Af- ter successful completing LUL call is automatically stop and there appears queries to complete the test or the test is in pro- gress, here option in progress is to be selected, After selecting VoL, the screen appears below which shows the details of long duration voice calling. The screen shows the GPS status and RTP Loss, VoL test is perform for long dura- tion by moving from one cell to another and collecting the data of proper handover takes place or not, interference, call disconnection. After completion of the VoL test, as VoL is the last test performed the complete option is selected to complete all the tests.
