ABSTRACT:
To support local number portability and service portability in a telephone network, a method and apparatus handle subscription and administrative service requests in a local service management system to maintain records at a service control point. The subscription requests include create, modify, and delete requests of records in the service control point. The administrative service requests include Numbering Plan Area (NPA) code split, mass change, and query and resend requests. The records at the service control point are accessible by switches via respective signal transfer points to determine the network addresses of the switches handling services and calls corresponding to a particular telephone number.
