Question: What is the primary purpose of configuring an MS (Mobile Station) with a permission for override of low access priority and Extended Access Barring restrictions in a telecom network?
Option 1: To ensure all MSs have equal access priority during congestion situations.
Option 2: To allow applications or users, who normally tolerate deferred access, to occasionally override low access priority for urgent network access.
Option 3: To enforce stricter access controls on subscribers with low-priority configurations.
Option 4: To simplify tariffing structures by eliminating variable access priorities.
Explanation: This option correctly identifies the primary purpose of the override permission, which is to cater to applications or users that can usually tolerate being deferred but may occasionally need immediate network access, thus requiring an exception to their normally configured low access priority. This aligns with the telecom concept of managing network resources and access priorities based on user or application needs, ensuring both efficient resource allocation and satisfactory user experience.
