Intellegent delivery agent for short message distribution center

Abstract

A message distribution center (MDC) and Intelligent Delivery Agent are implemented in a wireless Internet gateway interposed between content providers and a wireless carrier to subjectively examine and direct messages via simple mail transfer protocol (SMTP) based on desired rules (e.g., non-peak hours, paying subscribers only, etc.) using standard SMTP Gateway and other well-known protocols. The MDC includes an individual queue for each subscriber, and the provider is informed through conventional SMTP protocol messages that the short message has been accepted. If the carrier has specifically disallowed service for a particular mobile identification number (MIN) (e.g., in the case of churning), then the content provider is informed through an SMTP interchange that the recipient is invalid.

Dependencies are inferred from the claim text.
