UMTS allows operators to provide higher data rates and more capacity in their networks. This customized mentoring workshop for performance engineers delves deep into the behavior of UMTS and HSPA+ in real-world environments, providing insights into the symptoms and possible causes of field performance issues. This advanced level workshop assumes that the participants to have in-depth knowledge in UMTS and HSPA+ technology, RF Coverage and Containment, and Neighbor List Tuning, This workshop focuses on Access issues, Dropped Calls, Soft handover issues, HSPA+ Packet Switched data, Inter Frequency Handover and Inter Radio Access Technology (IRAT) Handovers. This knowledge transfer is achieved by using actual market specific data and tools. Participants will gain hands on experience in analyzing their own market data using market specific tools, drive data, counters, and vendor OSS tools and data. The exercises in each of the key areas will allow the participant to gain experience using post processing tools, as well as counters to identify, troubleshoot, and determine the root cause for specific setup, failure and throughput issues. Special Note: Market-specific network logs, configuration data, as well as statistical reports are needed three weeks prior to the course to deliver maximum value for the attendees. Our Subject Matter Expert (SME) will analyze the market specific data to identify and develop examples and exercises for each performance area discussed in the workshop.
Learning Objectives
After completing this course, the student will be able to: • Identify the different counters that are pegged by vendor products at different stages in the call flow for circuit and packet switched services • Use scanner and mobile drive plots to evaluate network coverage and interference levels • Identify and troubleshoot access failures and dropped calls using market-specific counters, parameters and tools • Understand the benefits and impacts of HSPA+ features • Describe HSPA+ data session setup and be familiar with the vendor-specific implementations • Evaluate HSPA+ network statistics to assess throughput performance and resource usage, and to identify potential problems • Describe the algorithms and parameters related to IRAT and IFHO, and the effects of changing these parameters
Intended Audience
This in-depth mentoring program is intended for wireless network operators, particularly RF/system performance engineers.
Suggested Prerequisites
• Very good knowledge of UMTS and HSPA+ signaling and technology • Familiar with vendor-specific tools, logs and counters • Able to use and analyze call logs, Excel spreadsheets and MapInfo files as required for the in-class exercises
