When setting priorities for any of the use cases outlined in Section 5 it is important to use the same priority values across applications. For instance, when defining priority for the First Responder use case discussed in Section 5.1 and the Emergency call use case discussed in Section 5.2 use cases, one high priority value might be used for all first responder messages, say PRIORITY_2, and a slightly lower priority value, say PRIORITY_3, might be used for emergency call related messages. These values should be specified for these use cases across all applications used within the Diameter administrative domain.
