NPA split management in intelligent network environment

A method operable in conjunction with a numbering plan area (NPA) split for updating information items in elements of the Intelligent Network and in a Service Management System, comprising the steps of:

• (a) said service management system receiving information defining an NPA split in which at least a defined portion of a telephone number must change as a result of said NPA split from a pre-split value to a post-split value;
• (b) said service management system determining which information items of said Intelligent Network elements are of a type which must change as a result of said NPA split;
• and
• (c) said service management system generating an instruction to said Intelligent Network elements to convert in said determined information items representations of said pre-split value into representations of said post-split value.

A system for managing a numbering plan area (NPA) split in a telecommunications network Intelligent Network environment having at least one Intelligent Network element containing a plurality of information items relating to a telecommunications service including a representation of said at least one telephone directory number, and the NPA split requiring a change in a defined portion of at least one telephone directory number of said telecommunications network, said system comprising:

• a service management system operatively coupled to said at least one Intelligent Network element;
• said service management system having a user interface for receiving information about said NPA split, said information including a representation of a pre-split value of said defined portion and a post-split value of said defined portion;
• said service management system further having indicia identifying information items of said Intelligent Network element which must be changed as a result of said NPA split;
• said service management system further having an instruction generator responsive to said indicia and said information about said NPA split for providing an instruction to said intelligent network element to convert representations of said pre-split value of said defined portion of said at least one telephone directory number to representations of said post-split value within said information items;
• said at least one Intelligent Network element further having a converter operative in response to said instruction to convert representations of said pre-split value of said defined portion of said at least one telephone directory number to representations of said post-split value within said information items;
• said at least one Intelligent Network element being adapted to maintain for each of said information items subject to conversion the converted version of such information item without maintaining an unconverted version of such information unit once conversion is complete.

• and
• (d) responsive to said instruction from said Service Management System, said Intelligent Network elements converting in said determined information items representations of said pre-split value into representations of said post-split value, and maintaining for each of said information items subject to conversion the converted version of such information item without maintaining an unconverted version of such information unit once conversion is complete.
