摘要

A METHOD FOR CONTROLLING ROUTING INFORMATION FOR INTELLECTUAL PERIPHERALS (IPs) IN A SUBSCRIBER-BASED RING-BACK-TONE SERVICE. THE ROUTING INFORMATION TO BE ROUTED TO IPs 50 CORRESPONDING TO SUBSCRIBERS IS CLASSIFIED ON A SUBSCRIBER TELEPHONE NUMBER-BY-NUMBER BASIS, A SUBSCRIBER TELEPHONE OFFICE NUMBER-BY-NUMBER BASIS, A SUBSCRIBER TELEPHONE OFFICE NUMBER GROUP-BY-GROUP BASIS OR A SUBSCRIBER'S MAJOR ACTIVITY AREA-BY-AREA BASIS ACCORDING TO A SELECTION. THE CLASSIFIED ROUTING INFORMATION IS SET AND REGISTERED IN A HOME LOCATION REGISTER (HLR) 10. WHEN THE HLR 10 RECEIVES A LOCATION REGISTRATION REQUEST MESSAGE FROM A TERMINAL OF AN ARBITRARY SUBSCRIBER, A CORRESPONDING ROUTING INFORMATION ITEM TO BE ROUTED TO AN IP 50 CORRESPONDING TO THE SUBSCRIBER'S TERMINAL AMONG THE CLASSIFIED, SET AND REGISTERED ROUTING INFORMATION IS CONTAINED WITHIN A RESPONSE MESSAGE TO THE LOCATION REGISTRATION REQUEST MESSAGE, AND THE RESPONSE MESSAGE IS PROVIDED TO A TERMINATING MOBILE SWITCHING CENTER (T_MSC) 32.FIGURE 3
