  • Method and apparatus for using DTMF for controlling context calls, and mutual context information exchange during mobile communication
    Publication number: 20020077086
    Abstract: A method for operating a wireless communication system includes steps of setting a context-sensitive facility in one of a mobile station or in a wireless network; informing a caller of the setting; and overriding the setting by sending a signal from the caller to the context-sensitive facility. The context-sensitive facility can be implemented as an answering service, the signal can be a DTMF signal generated in response to an input from the caller, and in this case the step of overriding forces the call through to a called parties' mobile station when the setting is to not allow calls to be made to the called parties' mobile station.
