Option 1: Only Sponsor Identity
Option 2: Only Application Service Provider Identity
Option 3: Both Sponsor Identity and Application Service Provider Identity
Option 4: Neither Sponsor Identity nor Application Service Provider Identity
Explanation: According to telecom standards for Policy and Charging Control (PCC) in Sponsored Data Connectivity, when both Sponsor Identity and Application Service Provider Identifier are included in PCC rules, offline charging reports must include usage details for each combination of Charging Key, Sponsor Identity, and Application Service Provider Identity, ensuring granular billing and accounting for sponsored data services.
