Question: How are Information Elements (IEs) typically notated in E-UTRAN S1 Application Protocol specifications?
Option 1: All letters in upper case characters without any additional identifiers.
Option 2: First letters in each word in upper case characters, with all letters in _Italic font_, followed by 'IE'.
Option 3: Written in lower case characters with the abbreviation 'InfoElem' at the end.
Option 4: Entirely in bold font without any specific case or additional abbreviations.
Explanation: This notation style for Information Elements (IEs) is crucial for clarity and consistency within telecommunications protocol specifications. The use of upper case initial letters in each word, combined with italic font and the 'IE' suffix, provides a visually distinct format for IEs, distinguishing them from procedures and messages. This precise notation helps developers accurately interpret and apply protocol standards in telecom network deployments.
