Question: When a Home Subscriber Server (HSS) supporting Diameter message priority receives a request with both Session-Priority Attribute Value Pair (AVP) and Diameter Resource Priority Message Priority (DRMP) AVP, how does the HSS prioritize the request?
Option 1: Based on the higher priority value between Session-Priority AVP and DRMP AVP, with lower numerical values indicating higher priority.
Option 2: By concatenating the priority levels of both AVPs to create a combined priority score, which determines the request's overall priority.
Option 3: According to the priority level received within the DRMP AVP, disregarding the Session-Priority AVP for prioritization purposes.
Option 4: The HSS will reject the request due to the ambiguity of having two priority mechanisms specified.
Explanation: This is correct because, as per the given context, when both Session-Priority AVP and DRMP AVP are present in a request to an HSS that supports Diameter message priority, the HSS specifically prioritizes the request based on the priority level received within the DRMP AVP. This indicates that in cases of dual specification, the DRMP AVP takes precedence for determining the request's priority.
