About Daniel Hernández

I specialize in making proposals and recommendations to improve the perfomance of the PS/CS Core network, based on the skills that I have obtained optimizing networks during more than 8 years for a complex network with a mixture of vendors (Alcatel-Lucent, Huawei and Ericsson), architectures (Monolitich and layered) and technologies (CDMA, GSM and UMTS). I have enough skills and knowledge to make in-depth analysis of data (including end-to-end call traces, protocols analysis, Key performance Indicators and other core network statistics) to provide recommendations about core network problems and, by other side, to make it more efficient based on studies about how to make reengineering of the installed capacity of the system in order to improve the performance and the quality of service. All of above, beside with my sense of urgency, compromise, proactivity, and focus on results, could help your consultant group to get success in any projectEspecialidades: Optimization of core network resources for voice cellular for multiple vendors (Lucent, Huawei y Ericsson).Protocol Analysis (ISUP, H.248, SIP-T, BICC, IS41, SIGTRAN).Statistical Analysis of Performance Indicators (Ineffectives Attempts, Answer ASR, ABR, TSR; bandwidth utilization, jitter and delay of VoIP).Administration and engineering of Tekelec’s STP and IAS.

  • Telecomunicaciones Movilnet C.A
    Ps/Cs Core Network Optimization Specialist
    Telecomunicaciones Movilnet C.A Jun 2012 - Sep 2016
    Venezuela
    As a Specialist of Optimzation I have generated reengineering proposals for core network resources in order to increase the profits of the company, and at the same time, improve the performance and the quality of voice service. These proposals have been implemented for core networks of multiple vendors: Lucent (CDMA), Huawei (CDMA) and Ericsson (GSM). I have based my proposals over the analysis of multiple protocols (ISUP, MEGACO/H.248, SIP-T, BICC, IS41, SIGTRAN); analysis of multiple Core Network KPI’s (Ineffectives Attempts, Answer ASR, ABR, TSR; TDM trunks utilization; bandwidth utilization, jitter and delay for VoIP); and dialing plan changes. I have experience in administrating and engineering of Tekelec’s STP and IAS.Some achievements are the proposals that helped to increase the profits of the company by: a. Implement and adjust the feature that block the retries of prepaid mobile with balance zero (those mobiles loaded the network with ineffective attempts to get internet access) and help to increase the creation of PDP contexts efficiency in 18%. b. Reduce by 20% the amount of signaling between PS Core Network Nodes and prepaid billing platform, through the adjustment of ActivityTestGprs (CAMEL) parameter and trim the size of the quotas allocated to users. c. Optimize hardware utilization of PS Core Network through reengineering GGSN pool to clear the pool of IP APN internet service through changes in the distribution of traffic generated in the access nodes; achieving an increase in the income of the corporation by incorporating active PDP 10,000 new entrants in one of the GGSN. This proposal also allowed one of the SGSN system could have redundancy for the GGSN's ineternet service.

I have experience in administrating and engineering of Tekelec’s STP and IAS.Some achievements are the proposals that helped to increase the profits of the company by:- The decrease of the percentage of Ineffectives Attempts in the CDMA network (from 26% to 2%) at the second quarter of 2006.- The increase of the new calls completed, in one case due to increase of Through Connect Ratio in TDM trunks; and in other case by reengineering of the idle capacity in TDM trunks, incorporating that capacity to TDM trunks congested for the mobile activation balance.- Saving on hardware investment for reengineering vocoders in Lucent CDMA network.- Saving time in evaluating the performance of the network with automated reports.
