Abstract

An active messaging system is associated with a short text messaging service of a digital cellular telephone system. An active messaging client is stored in a computer readable medium of a digital cellular telephone and provides interpretation and execution of an active message script included in a short text message received at the digital cellular telephone by radiant transmission. An active message gateway in communication with the short text messaging service receives short text messages from the digital cellular telephone and selectively forwards the short text messages according to whether they include an active message script. The active message script is a compact, high efficiency script compatible with execution on small devices with limited resources and processing power.
