Question: What is the primary purpose of the Data Coding Scheme Information Element (IE) when sent from the Radio Network Controller (RNC) to the Core Network (CN)?
Option 1: To specify the encryption method for secure data transmission between the RNC and CN.
Option 2: To indicate the quality of service (QoS) parameters for handling message priority at the User Equipment (UE).
Option 3: To identify the protocol used for message routing between the CN and external networks.
Option 4: To define the alphabet or coding scheme employed for message characters, ensuring proper interpretation at the UE.
Explanation: The Data Coding Scheme IE identifies the alphabet or coding scheme (e.g., GSM 7-bit default alphabet, UCS2, etc.) for message characters, ensuring the User Equipment (UE) interprets messages correctly. This is crucial for proper message handling and display on the UE, highlighting its role in seamless communication in telecom networks.
