How to manage multi-mode and multi-band networks? • Modes: GSM, UMTS, and LTE • Bands (MHz): 850, 900, 1800, 2100, 2600, … How to select features? • GSM, UMTS, and LTE: 211, 303, and 114 features • UMTS mobility management: 7 features • Intra-UMTS RRM: 15 features • GSM and UMTS RRM: 14 features • UMTS and LTE RRM: 10 features • LTE mobility management: 11 features How to know the impacts of features? • Features may impact on each other. • Key parameter configuration methods and requirements need to be clarified. How to coordinate macro and micro base stations in a HetNet? • RF plans and networking policies for macro and micro base stations are different. Page 7 How to Test and Evaluate Features? Performance counters are not described in some FPDs. How can I test and evaluate those features? Page 8 How to Find Information Quickly? The size of feature documentation is larger and larger, and too much redundant information is presented in search results. GSM, UMTS, and LTE feature documentation packages contain similar FPDs. Could you cut some of them so that I can read them more efficiently? How can I precisely locate the required information? Page 9 Our Solutions How to use features in combination? The product line provides solutions. • Adding solution documents • Consolidating feature documents How to test and evaluate features? The product line provides counters. • Adding performance counters • Adding troubleshooting cases How to find information quickly? • Improving search efficiency Page 10 Improvement 1: Adding Solution Documents Solution documentation Level 1 SingleRAN solutions Level 2 single-mode overall solutions Level 3 single-mode feature solutions Level 4 features Feature documentation Each solution document covers all the features involved in this solution. Page 11 Improvement 1: Adding Solution Documents We'll provide a documentation package containing all GSM, UMTS, and LTE solution documents. This documentation package involves the following traditional solutions: • Voice service • Data service • Radio and performance • Transmission and security • Operation and maintenance • Network development and planning • Business model optimization Multiple base station types Multiple modes and Multiple bands In addition, this documentation package involves the following newly concerned solutions: • Multiple modes • Multiple bands • Multiple base station types • Intelligent coordination Intelligent coordination Page 12 Improvement 2: Consolidating Feature Documents •Descriptions of similar features or topics in GSM, UMTS, and LTE documents are combined into one SingleRAN document. •Descriptions of the same topic in different documents are combined for easy finding.
