摘要:
The invention relates to the usage of downloadable ringtones for mobile communication devices that are customised depending on the emergency situation. By sending emergency messages to the mobile communication devices within an emergency area which are played back aloud, detailed emergency information providing information about the type of emergency and the action to be taken can be provided to a specific part of the population in the region affected by the emergency situation. Mentioned advantage is that the customised ringtone that is received by a person within the area in which the emergency message is to be broadcast can be heard by others standing in the vicinity of the mobile telephone, PDA, etc. receiving the alert message.

摘要:
A computer implemented system and method for providing at least one audible message at a communication device in replacement of a pre-determined telephone tone. There is provided a tone detector interface for detecting the pre-determined telephone tone provided at the communication device; an audible messages database accessible to the tone detector interface and the communication device, the audible messages database storing the audible messages; and a tone replacement module in communication with the tone detector interface. The tone replacement module, in response to detecting the pre-determined telephone tone, may provide the audible message, such as advertisements, in replacement of the pre-determined telephone tone.
