How to Use Features in Combination?
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.

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?

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.
