Question: In A/Gb and Iu mode, when an MS (Mobile Station) requests extended idle mode DRX (Discontinuous Reception) but the SGSN (Serving GPRS Support Node) accepts it with a longer cycle length than requested, what is the potential impact on the UE's (User Equipment) applications?
Option 1: Improved power efficiency without affecting application reachability.
Option 2: Adverse impact on the reachability requirements of applications running on the UE.
Option 3: No impact on the MS's ability to receive emergency bearer services.
Option 4: Immediate deactivation of all PDP (Packet Data Protocol) contexts.
Explanation: When the network accepts extended DRX with a longer cycle length than requested by the UE, it can negatively affect how quickly applications on the UE can be reached, as the UE will be in a dormant state for longer periods. This directly impacts the reachability requirements of those applications, potentially leading to delays or missed communications.
