ABSTRACT:
A telecommunications network (10) comprises a set of telephone service operator domains (20), including domains (20A-20C) having intelligent network-type services having non-geographic telephone numbers. A call-originating domain (20G) accesses a non-geographic service number database (30G) to obtain address information concerning the domain which currently handles the called service (90). The address information obtained from the non-geographic service number database includes the address a node in the domain which handles the service, e.g., the address of a gateway node (GW), and optionally the addresses of a service switching point (SSP), a service control function (SCF), and a service data function (SDF) which handles the called service (90). When changing telephone service operators (e.g., changing to a new domain), the non-geographic service number database is updated to reflect the change. Access of the database and usage of the addresses obtained therefrom in the routing message permit the service (90) to retain the same directory number when changing telephone service operators.
