Abstract: A method and apparatus are described for adapting a mobile terminal to different protocols in a wireless communication system. According to an exemplary embodiment, a script language is defined including a plurality of primitives that can be stored or pre-loaded in the mobile terminal. The script language is configurable to form a plurality of scripts using the primitives to describe a corresponding number of protocols. A script is downloaded from a service provider to the mobile terminal. The script defines an order in which the primitives that can be stored or pre-loaded in the mobile terminal are to be executed by the mobile terminal to form a protocol. The script is executed in the mobile terminal.
