SYSTEM AND METHOD FOR NUMBER PORTABILITY PROCESSING IN A TELECOMMUNICATIONS NETWORK

摘要

A system and method for number portability processing at a signal transfer point (204) are provided. The signal transfer point (204) includes additional processors (328, 358) and databases (332) for processing routing and service queries. A query message is received by the signal transfer point (204), a first database residing in the signal transfer point (204) is accessed to determine the location of a second database (332) also residing in the signal transfer point for processing the query message. The second database (332) is then accessed to obtain the requested information, which is delivered to the query originator, such as a central office (220, 222).
