Question: What is the primary factor excluded from the UTRAN Service Access Success Rate calculation for idle mode UEs to focus on service-related accessibility?
Option 1: Successful RRC setup repetitions and/or cell re-selections during RRC setup
Option 2: All types of call terminations (e.g., Conversational, Streaming, Interactive, Background)
Option 3: Originating calls with a background traffic type
Option 4: RAB establishments for non-conversational services
Explanation: The UTRAN Service Access Success Rate aims to evaluate the service accessibility provided by the UTRAN network. To maintain this focus, the calculation specifically excludes successful RRC setup repetitions and/or cell re-selections that occur during the initial RRC setup process, as these are not directly related to the success of accessing a service but rather to the connection establishment process itself. This exclusion ensures the KPI reflects the effectiveness of service access attempts, distinguishing between connectivity issues and service accessibility.
