摘要:
Calling name presentation services are provided by maintaining a local cache of requested information. When a called destination is determined to subscribe to calling name presentation, the local cache is queried to determine if the calling number is in the local cache. If the calling number is in the local cache, information corresponding to the calling number is retrieved from the local cache. If the calling number is not in the local cache, a remote database is queried for the information. The information retrieved from the remote database is stored in the local cache. In either case, the name information is sent to the call destination. A Signaling System 7 architecture may be used to implement local caching.
