Question: In a scenario where both EFACSGL and EFOCSGL are updated with new CSG IDs for H(e)NB selection, which list takes precedence over the one stored in the Mobile Equipment's (ME) non-volatile memory?
Option 1: Both EFACSGL and EFOCSGL lists take equal precedence over the ME's non-volatile memory list.
Option 2: Only the EFACSGL list takes precedence, regardless of EFOCSGL updates.
Option 3: The most recently updated list between EFACSGL and EFOCSGL takes precedence.
Option 4: Neither EFACSGL nor EFOCSGL lists take precedence; the ME's non-volatile memory list is always prioritized.
Explanation: According to specifications, both EFACSGL (for allowed CSG IDs) and EFOCSGL (for Operator CSG IDs) take precedence over the list stored in the ME's non-volatile memory when their respective services are available. This implies updates from either file override the ME's stored list, with no indication of one overriding the other.
