SYSTEM AND METHOD FOR HANDSET-INTEGRATED EMERGENCY AUDIBLE
BEACON
Field of the Invention
The present invention relates generally to the field of telecommunications. More specifically, the present invention relates to a system and method for triggering an audible beacon in a portable wireless phone that can be used by emergency service providers to locate individuals.
Related Art
In an emergency situation, a prompt response by emergency service providers can make the difference between life and death to an incapacitated individual- The existing wireless 911 systems are able to obtain only a cell-site location and a callback number for the wireless 911 caller. With this type of system, a problem is incurred when an individual is unable to speak, give locator information or respond to a telephone call if the emergency service providers decide to use the callback number. By October 2001, the typical wireless communications system will be able to locate an individual to within 125 meters of accuracy as required by the Enhanced 911 (E911) Phase II provision of a Federal Communications Commission (FCC) mandate for wireless communications.
Most often, locating an individual to within 125 meters only means pinpointing a building location, not an exact physical location of the individual This can present a problem to rescue workers when the building has multiple floors such as in skyscrapers, office buildings, or high rise apartment dwellings. With the existing location systems, the rescue workers have to search from room-to-room to locate an incapacitated individual in such a building. To perform a search using the room-to-room method is quite time consuming and impractical in an emergency situation.
What is needed is a system and method for assisting rescue workers in more quickly locating incapacitated individuals by pinpointing the individual's

location much more closely than the E911 Phase II standard of 125 meters of accuracy,
SUMMARY OF THE INVENTION
The present invention is a system and method for aiding emergency
service providers in locating an incapacitated individual by use of a wireless
communications device. Upon ej>tablishment of a call to a predetermined
telephone number, the audio beacon is initiated in the handset of a wireless
communications device. If, while the connection between the wireless
commimication device and the emergency services number is open, there is a
detection of a predetermined interruption in audio voice signals being
h-ansmitted from the wireless connmunications device, the audible beacon will
periodically emit a tone. The emitti.-d tone assists dispatched rescue workers in
more quickly locating disti-essed individuals by allowing the workers to listen
for the tone emanating from the handset of the phone. Upon termination of a
call to the emergency services telephone number, the audible beacon is
immediately irutiated. The audible beacon can also be remotely initiated from
the call destination location of the emergency service provider if, for example, it
becomes necessary to reinitiate tiie audible beacon after it has been manually
turned off. Once the audible beacr^- i^ initiated, the stored volume settings of
the handset are overridden by true tone of the beacon system. The tone
continues to be activated through true handset until it is manually tinned off.
An advantage of the present mvention is that the audible beacon allows rescue workers to more quickly locate mdividuals who may be tirapped inside bmldings with multiple floors and work spaces by permitting the rescue worker to pinpoint, via the emanation of ti-^e audible tone, the office space from which the call may have originated. The previous methods only allowed the rescue worker to determine the building fro-m which the call originated.
Further featiires and advarxa^es of the invention, as well as the operation of various embodiment'. --' the invention, are described in detail below with reference to the accomp^-T v:rtg drawings.

DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENTS
The present invention is particularly suited for use in communications systems employing standard portable cellular or satellite telephones. However, while the present invention is described herein with reference to illustrative embodiments for particular applications, it should be understood that the invention is not limited thereto. Those skilled in the art with access to the teachings provided herein will recognize additional modifications, applications, and embodiments within the scope thereof and additional fields in which the present invention would be of significant utility.
The present invention is a system and method for triggering an audible beacon that can be used with a wireless communications device. A primary purpose of the audible beacon system is to provide assistance to emergency service providers in locating individuals who are incapacitated. The present invention accomplishes this by emitting a tone through the speaker of a

telephone, which the rescue workers can use to home in on the location of the distressed individual.
Prior to describing the invention in detail, a description of the conununications device is provided. The communications device operates as a standard cellular or satellite telephone when a non-emergency service telephone number is dialed. The communications device operates in several modes to trigger an audible beacon when a predetermined telephone number for an en^ergency service provider is dialed. The predetermined number would typically be an emergency service number that connects directly to fire, police, or medical services. In the United States, the standard emergency service number is "911'FIG. 1 is a block diagram that illustrates the high level operation of the audible beacon system and routing of a call to an emergency service provider. The audible beacon system comprises a wireless conununications device 102, a wireless conununications network 104, a public switched telephone network (PSTN) 106, and an emergency provider 108. In one embodiment, wireless communications device 102 is a standard cellular telephone operating over a terrestrial cellular network. In an alternative embodiment, device 102 may be a satellite phone operating over a satellite communications network.
When a call to a predetermined telephone number is placed from telephone 102, the signal is sent to wireless communications network 104. In accordance with the E911 Phase H FCC provision, the wireless communications network 104 automatically requests a position fix coordinate from telephone 102. Telephone 102 responds with the appropriate position fix, which is then forwarded by wireless communications network 104 and PSTN 106 to emergency service provider lOd. The position fix information will locate phone 102 (and caller) within a radius of about 125 meters.
FIG, 2 represents a detailed flow diagram of the method of the invention for periodically triggering the audible beacon system when there is a cessation of audible signals transmitted from the communications device. The process begins with step 202.
In step 202, a telephone number is entered into telephone 102. In step 204, the determination of whether the telephone number dialed is an emergency services number is made. If the telephone number dialed is not an emergency

services telephone number, then m step ziu tne communications device functions as a standard cellular or satellite phone.
If at decision step 204, the telephone number dialed is determined to be an emergency services telephone number (for example, "911"), a link is established at step 206 between telephone 102 and the call destination. In step 208, the determination of whether voice quality audio signals are being transmitted is made. As long as voice quality signals are present, the telephone call to the call destination continues normally and is monitored at step 212 for the presence of voice quaUty audio signals.
If at decision step 208 voice quality signals are not detected to be present, then a timer is started to count dov/n a preset period in step 214, If the lapse of voice quality audio signals continues for the duration of the preset countdown period, then in step 216, the audible beacon is initiated to emit a selected phone ringer or beeping tone through the speaker of the telephone 102. If at decision step 214, the lapse of voice quality audio signals does not continue for the duration of the preset time period, then the call will continue to be monitored in step 212. The tone continues to be emitted from the speaker until step 218, when the tone is manually turned off at telephone 102.
FIG. 3 represents a detailed flow diagrani of the method for triggering the audible beacon system upon the termination of a call to a predetermined telephone number. The process begins with step 302.
In step 302, a telephone number is entered into telephone 102. In step 304, the determination of whether the telephone number dialed is an emergency services number is made. If the telephone number dialed is not an emergency services telephone number, then in step 310 the communications device functions as a standard cellular or satellite phone.
If at decision step 304, the telephone number dialed is determined to be an emergency services telephone number (for example, "911"), a link is established at step 306 between telephone 102 and the call destination. In step 308, the line of commimication between telephone 102 and the call destination remains open so that the incapacitated individual can converse with the call destination personnel. In step 312, the determination of whether the link is still present is made. As long as the link between telephone 102 and the call destination remain open, the call continues as normal. If in step 312, the link

between telephone 102 and the call destination is terminated, the audible tone is triggered to emit a selected phone ringer or beeping tone through the speaker of telephone 102. In step 316, the tone continues to be emitted from the speaker until manually turned off at telephone 102.
