Question: In a typical E-UTRA and EPC conformance testing setup for User Equipment (UE), what is the expected initial state of the UE before commencing tests, assuming default conditions apply?
Option 1: Connected Mode, with an established dedicated bearer
Option 2: Registered, Idle Mode state, pre-registered on HRPD (State 2B)
Option 3: Deregistered, with no prior network attachment
Option 4: In Service, with ongoing packet transmission
Explanation: For conformance testing of UE in E-UTRA and EPC environments, starting from a known, stable state is crucial. The 'Registered, Idle Mode state' ensures the UE is recognized by the network but isn't actively engaged in a call or data session, providing a baseline for testing various scenarios without pre-existing conditions influencing outcomes. Pre-registration on HRPD further specifies the initial setup, aligning with test environment defaults for focused evaluation of UE behavior under controlled conditions.
