Tems™ investigation gsm events such as handovers and dropped calls are indicated by symbols and (optionally) audio signals users can also define events of their own user interface all specifications are subject to alteration without prior notice printed in sweden tarle decor ab 122001. Radio network control system tv telephone, packet, and multi-call at a higher quality and higher rate than those of the 2nd generation mobile telecommunication system our radio network control system has a highly flexible and scalable structure this based on the 3gpp specifications, fujitsu has. Verified/monitored the parameters for cell id, uarfcn, scrambling codes, data throughput, transmit and receive power, dropped and blocked calls during the drive special purpose drive-testing for a pre & post comparison of a swap from umts 1900 to umts 850. Move along the boundary of the umts and gsm cells and evalu- ated the performance of the algorithm with the handover rate as a function of the various handover thresholds in both the networks.
• familiar with test specifications like vzw fit testing, at&t 10776, dg11, gcf etal • experience with windows mobile hopper and android monkey helpful • analyzing issues from logs, call failure analysis, call drop analysis, analyzing data throughput issues, signaling channel issues. Rf 2g-3g post processing using tems and mapinfo skip navigation sign in search investigating blocked call issue in gsm due to data link failure call drop analysis - duration:. Basic understanding of cops –son for umts networks (anr/plug n play/self healing/load balancing) imparting training for usage of cops and guidelines for analysis and troubleshooting hsdpa/hsupa/cs & ps call drop/pilot pollution/overshooters/neighbour planning issues using the tool. Tch blocking, sdcch blocking, sdcch drop rate, hosr) • actively participated in planning and optimization of universal service fund (usf) sites to deliver coverage to extremely remote areas.
In telecommunications, the dropped-call rate (dcr) is the fraction of the telephone calls which, due to technical reasons, were cut off before the speaking parties had finished their conversational tone and before one of them had hung up (dropped calls. • processing of tems log files collected during the drive tests (tool used:tems investigation 914) • rf analysis of logfiles and troubleshooting problems such as dropped and blocked calls, poor coverage (low rscp) and poor quality (low ec/no) and other radio related problems umts and lte design rf planning and optimization consultants. Significance : rsrp is the most basic of the ue physical layer measurements and is the linear average power (in watts) of the downlink reference signals (rs) across the channel bandwidth for the resource elements that carry cell specific reference signals knowledge of absolute rsrp provides the ue with essential information about the strength of cells from which path loss can be calculated. Call trace on iub by using crnc- & nodeb comm context ids + binding id & sugr + vpi/vci&cid drop call filtering upon iu release request sccp signaling allowing call tracing based on local reference numbers.
Perform kpi analysis(call drop, ho failure, rx quality, cssr, call blocking, irat ho)8 parameter level optimization for smooth handover and call continuity 9 preparing tssr, boq, as-in-built report for ibs sites and other technical supportive documents10. The present document may refer to technical specifications or reports using their 3gpp identities, umts identities or gsm identities these should be interpreted as being references to the corresponding etsi deliverables. Performed voice call testing for newly established and relocated sites for nsn-vodafone 2g drive test project using tems and helped in tuning cell foot-print to the predicted model.

Dropped and blocked call event cause 1 dropped and blocked call event cause category description ranking wcdma dropped event cause irat ho to gsm dropped call occurs during irat handover 1 missing neighbor strong detected set neighbor occurs prior to dropped call 2 soft ho dropped call occurs during soft- handover 3 poor dl coverage last best server rscp is below user-defined rscp threshold 4. Identifying field problems such as dropped calls, blocked calls, missing neighbor and give solutions to this problems performed single site, cluster sites and indoors and outdoors swap test analyzed drive test problems and determined the reasons for poor rf coverage and handover for network improvements. • responsible for monitoring the 3g data service, handover between umts and gsm upload/download activities, pinging, and making multiple long and short calls • responsible for troubleshooting the drive test equipment upon failure, setup communications ports, coordinate drive routes and update maps etc.

Rf engineer resume hire now ericsson experienced in ran optimization of umts network for better performance and quality of network dropped calls, blocked calls, handovers, and channel congestions analysis of drive data using actix, tems and optimization for assigned clusters by recommending/applying changes in irat/umts neighbors. As with all currently deployed cellular networks, whether it be a 2ggsm network or even a 3g umts one, an lte network will have to be optimized after deployment to provide better coverage, throughput, lower latency and seamless integration as the specification asks for the optimization process contains several steps. Call drop & block analysis in wcdma telecom source drop & block call analysis in wcdma content : umts_dropped & blocked call specificationsrar (1,0088 kb, 329 views) minimum 5g requirements the document is a summary of tems analyses it does not mention which equipment vendor that the operator is using.
Antenna (like the 3g umts network), a voice call with data sessions requires a potential call drop, then propose a drop-call predictor based on adaboost 25 jan 2011 (yep, this includes hspa 3g, which is often referred to as gsm. Analyze the drive test logs and perform troubleshooting report for plot of rscp, ec/no, handover performance, dropped call, blocked call and check interference to prepare drive test report by mapinfo, tems route analysis, and actix software.
