  • Methods and apparatus for local number portability in telecommunication systems
    Patent number: 6445785
    Abstract: A telecommunication system supports local number portability. The system includes a local number portability switch and a local number portability database accessible by the local number portability switch. The local number portability database contains a table for translating geographic numbers to routing information. The local number portability switch queries the local number portability database using a dialed geographic number in response to initiation of a call. The local number portability database translates the dialed geographic number to corresponding routing information and returns the corresponding routing information to the local number portability switch. The local number portability switch uses the corresponding routing information to route the call.
