Question: In UTRAN Iur interface RNSAP signalling, when the measured one-way radio signal propagation delay from UE (User Equipment) to Node B exceeds the range of the Propagation Delay Information Element (IE), how should the delay be represented?
Option 1: The Propagation Delay IE is set to zero, indicating an overflow condition.
Option 2: Only the Extended Propagation Delay IE is used to represent the value, ignoring the standard Propagation Delay IE range limit.
Option 3: The system automatically calculates and adjusts the delay to fit within the standard Propagation Delay IE range.
Option 4: The Propagation Delay IE is set to its maximum value, and the Extended Propagation Delay IE is additionally used to accurately represent the measured delay.
Explanation: According to the specified procedure for handling insufficient range in the standard Propagation Delay IE, setting it to its maximum value while utilizing the Extended Propagation Delay IE ensures that both the overflow condition is indicated and the precise propagation delay value is communicated, maintaining signalling accuracy in UTRAN networks.
