A subscriber's Home Location Register (HLR) sends an Interrogation marker to the subscriber's Mobile-services Switching Center/Visitor Location Register (MSC/VLR) instructing the MSC/VLR to forward all supplementary services messages from the subscriber to the HLR. When the subscriber's user terminal sends a supplementary services message to the MSC/VLR requesting a supplementary service, the MSC/VLR forwards the message to the subscriber's HLR. The HLR retrieves an address of an IP Multimedia Application Server associated with the subscriber, and sends the supplementary services message to the addressed Application Server for handling the supplementary services request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Supplementary services in communication networks","description":"A method and application server for handling a supplementary services message in a communication network.
