`(57) Abstract
`
`A system and method for enabling emergency call initiations in response to the detection of a vehicle accident is disclosed. A number
`of sensors (10) located about the vehicle, for example, air bag deployment sensors, initiate call activation signals upon detection of a vehicle
`accident. The emergency call activation signal is transmitted to an associated cellular telephone unit (15) via wireline or non—wireline
`communications, and a timer (35) initiates a timeout period. Once the timer (35) has measured the proper timeout period, an emergency
`call setup is begun. The emergency call setup may be discontinued at any point by a user abort command (115). Otherwise, the mobile
`switching center (65) serving the cellular telephone (15) is alerted to initiate an emergency call. The MSC (65) utilizes location information
`from the base station (60) of the cellular telephone (15) and emergency information (68) from the home location register (70) of the cellular
`telephone (15) to contact and provide an emergency operator with emergency information.

`EMERGENCY CALL INITIATOR
`
`BACKGROUND OF THE INVENTION
`
`Technical Field Qf the Invention
`
`The present invention relates to automatic emergency
`
`call initiation, and more particularly,
`
`to the use of a
`
`cellular
`
`telephone
`
`for
`
`automatically initiating an
`
`outgoing call in response to a vehicle accident.
`
`Description of Related Art
`
`Emergency situation handling is an important reason
`
`for the success of cellular system technologies.
`
`In the
`
`event of an emergency situation, a cellular subscriber can
`
`initiate a 911 call to summon police, fire department or
`
`ambulance.
`
`The subscriber orally conveys the nature of
`
`the
`
`emergency,
`
`the
`
`location
`
`and
`
`other
`
`necessary
`
`information to the emergency operator.
`
`However,
`
`this
`
`scenario mandates
`
`that
`
`the
`
`subscriber
`
`initiate the
`
`emergency call. Thus,
`
`the subscriber must be conscious,
`
`alert and capable of manipulating the equipment
`
`in taking
`
`the appropriate steps necessary to make an emergency call.
`
`Often,
`
`the subscriber may be unconscious and unable
`
`to initiate an emergency call.
`
`The subscriber may also
`
`be in a state of shock or
`
`trapped such that
`
`they are
`
`unable to reach the cellular equipment.
`
`In cases such as
`
`this,
`
`time is of the essence and delay can result in death
`
`or permanent
`
`injury.
`
`Thus,
`
`a means
`
`for automatically
`
`initiating an emergency call through a cellular telephone
`
`system in response to a vehicle accident without the need
`
`for subscriber initiation would be greatly beneficial.
`
`SUMMARY OF THE INVENTION
`
`The present
`
`invention overcomes the foregoing and
`
`other‘
`
`problems with an apparatus
`
`for
`
`initiating an
`
`emergency telephone call from a cellular telephone unit
`
`in response to a vehicle accident.
`
`The apparatus operates
`
`in conjunction with the air bag deployment sensors located

`
`on many vehicles. Activation of the sensors to deploy the
`
`air bags also generates an emergency' call activation
`
`signal. Additional sensors also may be added to detect
`
`for vehicle accidents which may not cause deployment of
`
`5
`
`the air bags
`
`in a vehicle.
`
`The activation signal
`
`transmitted between the sensors and the cellular telephone
`
`unit may
`
`be
`
`through
`
`a wireline
`
`or
`
`non— wireline
`
`communications
`
`link.
`
`The
`
`emergency call activation
`
`signal activates a timer for delaying initiation of an
`
`10
`
`Ioutgoing call to an emergency number, such as 911.
`
`Upon expiration of
`
`the timer period,
`
`a processing
`
`means
`
`associated with
`
`the
`
`cellular
`
`telephone unit
`
`initiates an emergency call setup to the mobile switching
`
`center servicing the telephone unit.
`
`The emergency call
`
`15
`
`setup request
`
`from the telephone unit causes the mobile
`
`switching center
`
`to access
`
`an
`
`emergency information
`
`database including emergency data for the subscriber of
`
`the cellular telephone unit.
`
`The emergency information
`
`database is located within the home
`
`location register
`
`20
`
`(HLR)
`
`for the cellular unit and includes information for
`
`transmission to the emergency operator, such as, medical
`
`information,
`
`vehicle
`
`information,
`
`doctor's
`
`name,
`
`insurance, and other contact persons.
`
`The base station
`
`provides the cellular telephone unit's location.
`
`This
`
`25
`
`information along with the emergency information obtained
`
`from the database within the HLR of the cellular telephone
`
`unit
`
`is
`
`transmitted
`
`to
`
`the
`
`emergency
`
`operator.
`
`Additionally,
`
`the database within the HLR may include
`
`numbers of appropriate contact persons to be automatically
`
`30
`
`called in the case of an emergency.
`
`A one way page to
`

`
`DETAILED DESCRIPTION OF THE DRAWINGS
`
`Referring now to the Drawings, and more particularly,
`
`to FIGURE 1,
`
`there is illustrated a block diagram of the
`
`15
`
`emergency call
`
`initiation apparatus
`
`of
`
`the present
`
`invention.
`
`The apparatus includes a plurality of sensors
`
`10 strategically located about a vehicle to detect an
`
`accident
`
`involving the vehicle. Preferably,
`
`the majority
`
`of
`
`the
`
`sensors
`
`10
`
`comprise
`
`those
`
`sensors which
`
`20
`
`automatically deploy a vehicle air bag in the event of
`
`front or side accident. Additional sensors 10 can be
`
`added to the rear and top of the vehicle to detect a rear
`
`accident, vehicle rollover or other
`
`type of vehicle
`
`accident or emergency.
`
`25
`
`In the event of an accident,
`
`the appropriate sensor
`
`10 generates an activation signal indicating that an air
`
`bag has been deployed or an accident has occurred, and the
`
`activation signal is transmitted to the cellular telephone
`
`15.
`
`Transmission of
`
`the activation signal between the
`
`30
`
`sensor 10 and cellular telephone 15 is accomplished using
`
`a transmitter 20 associated with each sensor 10.
`
`The
`
`transmitters 20 provide a wireless RF connection between
`
`the
`
`sensors
`
`10
`
`and the antenna
`
`25 of
`
`the cellular
`
`telephone 15.
`
`The transmitter 20 need only transmit a low
`
`35
`
`power signal as the communications between the sensor 10
`
`and cellular telephone 15 only travel within the limited
`
`distance covered by the area of an automobile. While the

`
`_4_
`
`preferred embodiment is described with respect to the use
`
`of a wireless connection between the sensors 10 and the
`
`cellular telephone 15,
`
`the system may also have a wireline
`
`connection between the sensors and the cellular telephone
`
`5
`
`in an alternative embodiment.
`
`In one embodiment,
`
`the activation signal transmitted
`
`from the sensors 10 is processed by the receiver circuitry
`
`28 of
`
`the cellular
`
`telephone
`
`15
`
`and provided to a
`
`processor 30 programmed to activate an emergency call
`
`10
`
`setup in response to the activation signal.
`
`The processor
`
`30 compares the strength of
`
`the activation signal
`
`to a
`
`preselected threshold level and if the signal strength
`
`meets
`
`this level,
`
`the processor activates a
`
`timer 35
`
`located within the cellular telephone 15.
`
`The timer 35
`
`15
`
`provides a preselected time delay before initiating an
`
`outgoing emergency call
`
`in response to detection of a
`
`vehicle accident.
`
`An audio or visual indication notifies
`
`the passengers of activation of the timer 35 and ceases
`
`with expiration or cutoff of the timer.
`
`The time delay
`
`20
`
`enables the passengers in the vehicle a period of time to
`
`gather their wits after an accident. Certain types of
`
`signals
`
`from the
`
`sensors
`
`10,
`
`for
`
`example,
`
`signals
`
`indicating a fire or a vehicle rollover, may directly
`
`initiate the call rather than the timer 35 since time
`
`25
`
`would be of the essence.
`
`After the time delay period expires the processor 30
`
`initiates emergency call setup and provides an audible
`
`indication
`
`of
`
`this
`
`through
`
`audio
`
`output
`
`40.
`
`Alternatively, a short message service (SMS) message, or
`
`30
`
`CDPD message may be initiated upon timer expiration.
`
`An
`
`individual may cancel
`
`initiation of an emergency call
`
`through the user interface 45 if no emergency assistance
`
`is required.
`
`If the individual discontinues the emergency
`
`call through the user interface 45,
`
`the timer 35 resetsr
`
`35
`
`and the processor
`
`30
`
`awaits detection of
`
`a
`
`further
`
`activation signal.

`
`Alternatively,
`
`as
`
`shown in FIGURE 2,
`
`rather than
`
`processing the
`
`received activation signal
`
`from the
`
`transmitter~ 20 using'
`
`the processor‘ 30, dual
`
`receiver
`
`signal circuitry may be utilized to process RF signals
`
`5
`
`received via the antenna 15 of
`
`the cellular telephone
`
`unit.
`
`Phone circuitry 50 processes received cellular
`
`signals in a normal
`
`fashion.
`
`The sensor circuitry 55
`
`processes low power RF signals from the transmitter 20.
`
`The sensor circuitry 55 would use hard—wired logic to
`
`10
`
`detect the activation signal from the transmitter 20 and
`
`determine whether the signal strength met
`
`the threshold
`
`requirement necessary to initiate the timer 35 and carry
`
`out
`
`emergency call
`
`setup
`
`in the manner discussed
`
`previously.
`
`15
`
`Referring back now to FIGURE 1, once the timer 35 has
`
`measured the predetermined time period,
`
`a call,
`
`SMS or
`
`CDPD setup procedure is initiated between the cellular
`
`telephone 15 and a base station 60.
`
`The base station 60
`
`forwards the emergency call setup request and the location
`
`20
`
`of the cellular telephone to the mobile switching center
`
`(MSC)
`
`65
`
`responsible
`
`for
`
`controlling the
`
`cellular
`
`telephone 15.
`
`The MSC 65 contacts the home
`
`location
`
`register (HLR)
`
`70 for the requesting cellular telephone
`
`15.
`
`A database
`
`68 within the
`
`subscriber
`
`account
`
`25
`
`information for the cellular telephone 15 stores a variety
`
`of emergency information associated with the subscriber
`
`of the cellular telephone unit 15.
`
`The information stored for forwarding to an emergency
`
`operator,
`
`may
`
`include
`
`emergency’ messages
`
`to
`
`be
`
`30
`
`transmitted, medical
`
`information on
`
`the
`
`subscriber,
`
`vehicle
`
`information,
`
`doctor's
`
`name,
`
`and
`
`insurance
`
`information.
`
`The emergency information,
`
`including the
`
`emergency messages
`
`transmitted, may
`
`be
`
`changed
`
`and
`
`customized by the user. This is accomplished by accessing
`
`35
`
`the database 68 through the cellular telephone unit 15.
`
`This emergency information is forwarded to the MSC 65
`
`controlling the cellular telephone 15.

`
`contacts
`
`the
`
`base

`
`to request
`

`
`information for the cellular telephone 15.
`
`The
`
`emergency
`
`information
`
`and
`
`the
`
`location
`
`information provided by the base station 16 are then
`
`5
`
`forwarded to an emergency operator,
`
`for example,
`
`a 911
`
`operator,
`
`through a public switched telephone network 75.
`
`The
`
`emergency
`
`information can
`
`be
`
`forwarded to the
`
`emergency operator by audio, pager or in short message
`
`form.
`
`In addition,
`
`the emergency information within the
`
`10
`
`database 68 of
`
`the subscriber's HLR 70 may include an
`
`emergency notification call list. This list might
`
`include
`
`the subscriber's spouse, parent, or other
`
`individuals
`
`needing to know of the subscriber's accident and a message
`
`to be transmitted. This information is also customizable
`
`15
`
`by the user.
`
`The MSC 65 uses this information from the
`
`HLR 75 to initiate one—way pages to the individuals on the
`
`emergency call list.
`
`Selected prerecorded information
`
`will
`
`be
`
`conveyed during these pages
`
`to the
`
`listed
`
`individuals.
`
`20
`
`Once the emergency call has been initiated to the
`
`emergency operator,
`
`the MSC 65 may instruct
`
`the base
`
`station 60 to transmit a continuous loop of emergency
`
`information to the cellular telephone unit 15 by SMS or
`
`pager message.
`
`This information may include emergency
`
`25
`
`medical
`
`information on the subscriber, such as a personal
`
`medical profile,
`
`taken from the emergency database 68 or
`
`may include general first aid information to be utilized
`
`By turning the

`cellular telephone unit 15 off and on,
`the continuous loop
`
`30
`
`of emergency information is discontinued and the cellular

`
`Referring now to FIGURE 3,
`
`there is illustrated a
`
`flow chart describing the overall method for enabling
`
`35
`
`automatic emergency call initiation.
`
`Initially, at step
`
`90,
`
`the system waits

`
`Once
`
`an accident
`
`is detected. by the sensors 10,
`
`the
`
`sensors generate an emergency call initiation signal and
`
`transmit the signal to the cellular telephone 15 at step
`
`95.
`
`The emergency call initiation signal is processed by
`
`5
`
`either the processor 30 (FIGURE 1) or sensor circuitry 55
`
`(FIGURE 2)
`
`to determine whether or not
`
`the proper signal
`
`level threshold has been reached at inquiry step 96.
`
`If
`
`so,
`
`inquiry step 97 determines
`
`if
`
`a
`
`time critical
`
`accident,
`
`such. as
`
`a
`
`fire, has been. detected.
`
`If
`
`a
`
`10
`
`critical accident
`
`is detected,
`
`the MSC is immediately
`
`alerted at step 120. Otherwise,
`
`the timer is activated
`
`at step 100. When inquiry step 96 determines that
`
`the
`
`signal
`
`level
`
`threshold has not been reached control
`
`is
`
`returned to step 90.
`
`15
`
`Inquiry step 105 monitors the timer 35 for expiration
`
`of
`
`the timing period. Until
`
`timer expiration,
`
`a call
`
`setup indicator is provided at step 106. Once the timer
`
`period expires,
`
`inquiry step 115 checks for a user abort
`
`command discontinuing the call setup procedure.
`
`If an
`
`20
`
`abort command is detected, control passes back to step 90,
`
`and
`
`the
`
`system waits
`
`for
`
`receipt
`
`of
`
`an additional
`
`emergency call initiation signal.
`
`If call setup is not
`
`aborted,
`
`the call setup procedure alerts, at step 120,
`
`the
`
`MSC 65 to automatically initiate an emergency call.
`
`25
`
`At step 125,
`
`the MSC 65 contacts the home location
`
`register 70 for the cellular telephone 15 and receives all
`
`emergency call information contained within the database
`
`68 of the home location register. Cellular telephone 15
`
`location information is retrieved at step 126.
`
`This
`
`30
`
`information plus the is then forwarded at step 130 to an
`
`emergency' operator via an emergency call.
`
`Once
`
`the
`
`emergency call has been sent,
`
`the MSC 65 further initiates
`
`automatic call
`
`setup to other contacts listed in the
`
`subscriber's emergency call contact list at step 135 and
`
`35
`
`then
`
`subscribers
`
`emergency medical profile
