Question: In UTRAN Iu-BC interface using SABP, when a receiving node encounters a Protocol Error, into how many classes can such errors be primarily categorized for handling and reporting purposes?
Option 1: Two classes: Syntax Error and Logical Error
Option 2: Three classes: Transfer Syntax Error, Abstract Syntax Error, and Logical Error
Option 3: Four classes: Message Syntax Error, Protocol Syntax Error, Abstract Syntax Error, and Logical Error
Option 4: One overarching class: General Protocol Error with sub-categorizations
Explanation: In the context of handling and reporting protocol errors in SABP for UTRAN Iu-BC interface, understanding the specific nature of the error is crucial. The three distinct classes - Transfer Syntax Error (related to data formatting), Abstract Syntax Error (pertaining to message structure), and Logical Error (concerning the validity of the information exchanged) - allow for more precise identification, reporting, and potentially, more effective resolution of errors. This categorization reflects a nuanced approach to error management in telecommunications protocols.
