Question: What is the primary purpose of utilizing the Extended Propagation Delay in UTRAN's Iur interface RNSAP signalling?
Option 1: To accommodate one-way radio signal propagation delays from MS to Node B exceeding the standard Propagation Delay IE range limitations.
Option 2: To enhance security by introducing a variable delay in signal transmission between the Mobile Station (MS) and Node B.
Option 3: To facilitate faster handover decisions by reducing the perceived latency in signal propagation from Node B to the MS.
Option 4: To enable the support of additional frequency bands not covered by the standard Propagation Delay measurements.
Explanation: The Extended Propagation Delay handles instances where the one-way radio signal propagation delay from the Mobile Station (MS) to Node B surpasses the range represented by the standard Propagation Delay Information Element, ensuring accurate handling of longer delays for efficient network operation and synchronization.
