METODA DAN PERALATAN UNTUK MEMPROSES PERMINTAAN DAN PEMELIHARAAN CATATAN-CATATAN DALAM SUATU SISTEM KOMUNIKASI

摘要

A method and apparatus for supporting local number portability and service portability in a telephone network (100) are disclosed. Subscription and administrative service requests are processed by local service management systems (LSMSs) (140a, 140b) and records are maintained at service control points (SCPs) (145a, 145b). The subscription requests include create, modify, and delete request of records in the SCPs (145a, 145b). The administrative service requests include numbering plan area (NPA) split, mass change, and query and resend requests. The records at the SCPs (145a, 145b) are accessible by switches (115a, 115b) via respective service transfer points (STPs) (120a, 120b) to determine the network addresses of the switches (115a, 115b) handling services and calls corresponding to a particular telephone number.
