Abstract
A user may transmit a character based message to invoke a request for emergency services from a public safety access point (PSAP) similar to a conventional voice call made to “911”. If the PSAP is capable of directly receiving a character based message, a user's message to a predetermined emergency address is routed to an appropriate PSAP. If the PSAP is not capable of directly receiving a character based message, the user's character based message is converted by a text-to-speech facility and transmitted over a conventional voice channel to an operator of a PSAP.
Claims15
A method for transmitting a character based message from a user in a telecommunication system to a public safety answering point comprising the steps of:
- receiving an emergency character based message addressed to a predetermined emergency address;
- identifying a first public safety answering point to receive the emergency character based message;
- determining if the first public safety answering point is capable of receiving the emergency character based message in character based format;
- if the first public safety answering point is capable of receiving the emergency character based message in character based format, then transmitting the emergency character based message to the first public safety answering point by substituting a first message address of the first public safety answering point for the predetermined emergency address.
A method for transmitting a communication derived from a character based message from a user in a telecommunication system to a public safety answering point comprising the steps of:
- receiving an emergency character based message addressed to a predetermined emergency address;
- identifying a first public safety answering point to respond to the emergency character based message;
- translating with a text to speech translator the character based message into voice communications that are transmitted to the first public safety answering point.
An apparatus for communicating information contained in a character based message from a user in a telecommunication system to a public safety answering point comprising:
- means for receiving a character based message addressed to a predetermined emergency address;
- a text to speech translator coupled to the receiving means translates the character based message into voice communications;
- means for transmitting the voice communications to the public safety answering point.
