Question: At what point is an attempt counted towards the 'Attempted Paging Type 1' measurement in a UTRAN network?
Option 1: Upon receipt of a RRC PAGING TYPE 1 message by the UE from the RNC.
Option 2: During the setup of a circuit-switched or packet-switched call.
Option 3: On transmission by the RNC of a RRC PAGING TYPE 1 message to the UE.
Option 4: After a successful paging procedure, as indicated by a response from the UE.
Explanation: The count increments at the point of transmission by the RNC of a PAGING TYPE 1 message to the UE, highlighting the importance of understanding network signaling and when specific events are measured within telecom networks, particularly in UTRAN environments.
