Real time services can be prioritized over non realtime services. P-GW Handoff KPIs for VoWiFi Feature Changes Currently, there are no statistics to determine the number of new sessions started on a particular RAT technology and to monitor any inter-technology handovers per APN. TechTrained is one shop stop on 4G LTE, Telecommunications, with a mix of technology, learning and society LTE PCI Planning and things to avoid when doing PCI planning for LTE This article discusses 5 PCI planning myths and challenges. We use this data in times of congestion to apply congestion management policies on the affected cells. Based on the KPIs measurements results, it is showed that the proposed method to expand the bandwidth from 10 MHz to 15 MHz can avoid congestion problem and impact on improving the performance of. KPI means for key performance indicator, which is measure from all the related aspect of network such as call setup success rate (CSSR), Handover success rate (HOSR), Paging, network access, congestion etc. Manager RF Optimization activities and compliance of Key Performance Indicators of LTE/CDMA networks for provision of best QoS and QoE to PTCL customers in North zone, including AJK, ITR & RTR. Analyzer: drive test post processing Analyzer is a desktop solution for drive test post-processing supporting network optimization, network acceptance and validation. - Reduce congestion and drops: CSSR, RRC Connection and RAB Establishment Success in the designated area for all voice and data services. Traffic analysis and recommending expansions (Enable/Disable HR, DHR, addition of TRXs etc) on effected sites. Documents or explanation would be most appreciated (Huawei Equipment). Topic: LTE KPIs Tutorial Target audience: Optimization & Tuning 2012-06-26 | Page 1 Abstract The purpose of this document is to provide a description on the LTE KPIs and give troubleshooting guidelines to under - performing EUTRAN KPIs in the areas of Accessibility, Retainability, Integrity, Mobility and Availability. Access Network KPI Viewer Transmission Network KPI Viewer PS/CS Core Network KPI Viewer Accesibility Network KPI’S • SDCCH Congestion • SPTCH Congestion • RRC Failures Retainability Network KPI’S • TCH Drop rate • SDCCH Drop rate • RAB Failures • CSFB Success Rate Mobility Network KPI’S • Incoming HO Success Rate. Responsible for the Radio Access Optimizer area for LTE 4G Networks for Minera BHP, in Minera La Escondida, with remote management and monitoring from Santiago de Chile, and thus ensure autonomy with preventive and corrective actions obtaining optimum levels of the KPIs of the 4G LTE Network at 99. LTE is different from other technologies that call themselves 4G because it is completely integrated into the existing cellular infrastructure for 2G and 3G. OSS KPI Achievement. Atoll and its Live module support a number of RAN optimisation use cases where the combination of predictions and measurements provide key advantages: identify congestion areas where additional capacity is needed, tune antennas and network parameters, plan neighbours and codes (LTE and 5G NR PCI, UMTS Scrambling codes). 2 Definition Table 9-2 IU Paging Congestion Ratio KPI Name IU Paging Congestion Ratio Measurement RNC Scope IUPagingLo ss Formula IUPagingCR = × 100% IUPagingAt tempt Associated See ANNEX Counters Notes None 9. Although the data load on LTE 2600 increased in both the reference and the text clusters, it increased by twice as much in the CellMax cluster (22% vs 44%). - Daily usage of the following tools: Arieso, Actix, CM Plan Editor, CM operation Manager, Reporting Suites, RNC object Browser and WBTS site Manager from NSN OSS NetAct. View Yasanka Lakshitha’s profile on LinkedIn, the world's largest professional community. Key Performance Indicators for Telecom Industry are :-Systems and Network Performance Analysis / Capacity Planning. fly please skip. For handover to UTRAN or GSM, a UE camped on an LTE cell will receive a UMTS neighbour cell list containing up to 32 primary scrambling codes per UMTS carrier and a GSM neighbour cell list with at least 32 GSM carrier numbers. - Meeting with TMV customer for optimizing problem area, worstcells optimization and cluster KPI optimization. The different test cases of LTE KPI are mentioned for each of the KPI categories. In UMTS, the uplink interference may vary due to several factors, such as the number of users in the cell, the Service, Connection Types and Conditions of Radio, etc. • LTE network coverage and quality optimization by electrical and mechanical tilts and orientation adjustment. Documents or explanation would be most appreciated (Huawei Equipment). • Taking care of Daily KPIs like (Accessibility, Retainability, Mobility & throughput). Coordination with Planning, Operations, Vendors, Sales & Customer Support teams. This allows the UE to calculate which PRACH preamble it can use to attach to the cell. After 1/31/2021, pay $60/mo. · Responsible for periodic Network Parameter, NBR , TAC-LAC consistency checks · Perform LTE feature recommendations and trials. KPI - Key Performance Indicators Hi, KPI tells the performance of a network on a daily/weekly/monthly basis, which helps to improve the network, so that operator & customer both enjoys the service at its most. The optimization of LTE networks mainly refers to pre-optimization before and continuous optimization after a network is launched. So, let us get started without wasting any further time. Knowledge of commands to get print out BSC/Cell level parameters (2G, 3G, LTE). The Root Sequence Index is broadcast as part of PRACH configuration in SIB 2 of the LTE cell. Key Performance Indicators for Telecom Industry are :-Systems and Network Performance Analysis / Capacity Planning. on market and super cluster level. • Soft parameter optimization for KPI improvement including accessibility, retain-ability & mobility • Capacity analysis of LTE network and proposal for expansion and different solutions to mitigate congestion.
