Methods and systems for improved caller name identification on a telephone network

摘要

A phone network in a wireless environment that does not perform CNAM queries when a number is already stored in the receiving handsets' caller directory. CNAM query fees are charged only to obtain caller information on a new caller. The network does not make CNAM queries when the caller information is already available, whether in the contact information stored on the receiver's handset or through some other reliable source.
