Question: In an IMS session, what type of service interaction information can Application Servers (ASs) exchange to avoid conflicting interactions between their executed services?
Option 1: Only the list of supported media types for ongoing sessions.
Option 2: Indication of performed services and optionally, services to be further avoided.
Option 3: Information about the subscriber’s current location and device capabilities.
Option 4: Details of the session’s Quality of Service (QoS) parameters.
Explanation: To prevent service conflicts in an IMS session, Application Servers need to share specific interaction details. This includes notifying each other about services already executed (to avoid duplication or conflict) and, if necessary, alerting about services that should not be initiated (to prevent incompatible interactions). This exchange ensures seamless and coordinated service delivery across different ASs within or across operator networks.
