Abstract

A method of provisioning a local number portability capable communication network which comprises numerous service provider networks, with updated signalling routing information to reflect a porting change is disclosed. A central administration center first updates the ported to network with updated signalling routing information. After the ported to network has been successfully updated the central administration center then proceeds to update all intermediate service provider networks. After confirmation has been received that all intermediate networks have been successfully updated the central administration center then proceeds to update the ported from network. Provisioning of networks which include intermediate networks supported by a central administration center in the predetermined manner and sequence disclosed can advantageously prevent signalling messages from looping between non-synchronized networks. The provisioning sequence works equally well where only two networks are involved, i.e. the ported from and ported to networks.
