`COMPUTER INTEGRATED TELEPHONY
`SYSTEM FOR THE PROCESSING OF 9-1-1
`CALLS FOR SERVICE
`
`This application is a continuation of application Ser. No.
`Oil/234.469. filed Apr. 26. 1994. now abandoned.
`
`BACKGROUND OF THE INVENTION
`
`FIG. 1 shows a typical prior art system which embodies
`essential features of an existing 9-1-1 service. In prior
`embodiments of a 9-1-1 service. a caller 100 dials 9-l~1 and
`is connected to a public safety answering point 105. here-
`inafter referred to as PSAP. via a dedicated partition in the
`public switched telephone network (PSTN). The appropriate
`PSAP is determined according to the caller’s location.
`Typically.
`local PSAP service areas are determined by
`geopolitical jurisdictions; arbitrarily defined geographical
`regions that are specified by public safety agencies.
`At the PSAP 105 the automatic number identification
`(ANT) controller 110 decodes the incoming calling party
`identification or telephone number of the inbound 9-1-1 call.
`The ANI controller 110 passes the 9- 1-1 telephone call to the
`telephone PBX switch 115 for presentation to one of a
`number of possible call-takers 120. where a call-taker is an
`individual who is assigned to accept incoming 9-1—1 calls.
`The identification of the specific call-taker. e.g.. call-taker 1
`125. receiving the call is passed back to the ANT controller
`110. With this information the ANI controller 110 (1)
`displays the citizen’s telephone number at the appropriate
`call-taker’s position and (2) passes the caller’s telephone
`number and the call-taker’s identification to the automatic
`location identification (ALI) controller 130.
`The ALI controller 130 queries a remote database service
`(RDBS) 135 to retrieve an address associated with calling
`party’s telephone number. Remote database services are
`typically maintained by telephone exchange carriers such as.
`for example. Southwestern Bell. A response from the RDBS
`135 is received by the ALI controller 130 and the location
`information is then displayed to the designated call-taker
`125.
`
`The call—taker 125 determines the nature of the emergency
`and conferences/transfers the incoming call to the appropri-
`ate service provider. i.e.. police 140. Fire 145. Emergency
`Medical Services 150. or other service as required 155. In
`addition to transferring the call. it may be necessary for the
`call—taker 125 to transmit the caller’s identification (e.g..
`telephone number) and location information.
`If the incoming call has been made from a mobile
`telephone. the call-taker 125 is responsible for determining
`the caller’s location (calling party identification and location
`information are not currently available for calls placed from
`mobile telephones). This is generally accomplished by
`manually referencing a detailed local map. such as a “KEY
`MAP” in combination with talking with the caller. Once the
`caller’s location has been determined.
`the call—taker can
`transfer the call and. if necessary. the caller’s identification
`and location information to the appropriate agency.
`A 9-1-1 system such as that shown in FIG. 1 has several
`shortfalls. including:
`1. Lengthy call transfer time (typically 4 to 6 seconds).
`2. Associated with the call transfer process is often a
`series of audible clicking (analog circuit bridging)
`noises which the caller may interpret as having been
`disconnected and may lead the caller to hang up while
`a call transfer is in progress.

`3. The reliability of the data transfer process. in those
`cases where it is necessary. is wholly dependent on the
`call—taker’s performance.
`4. The time required for a call—taker to manually deter—
`mine the location of a cellular caller is often measured
`in minutes.
`
`5. In many conventional 9-1-1 service sites incoming calls
`are (analog) recorded on magnetic tape. The process of
`later retrieving a specified call
`is often a time
`consuming. cumbersome ordeal
`that
`takes several
`hours or days.
`The machine executed method of the claimed invention
`addresses these shortfalls by providing a faster. more
`reliable. and cost effective means of processing 9-1-1 calls
`for service.
`
`2. SUMMARY OF THE INVENTION
`
`The claimed invention is a machine executed method—
`embodied in a series of computer programs—that provides:
`1. The rapid. automatic. and virtually silent transfer of an
`incoming call to the proper service provider or provid—
`ers.
`
`2. The automatic transfer of caller identification and
`location information from the call-taker station to the
`appropriate service provider without further call-taker
`intervention.
`
`3. Elimination of the need for a call-taker to manually use
`detailed local maps. such as a “KEY-MAP.” to deter-
`mine the location of a caller who is using a mobile
`telephone.
`4. The digital recording of incoming calls. The digital
`voice and associated information is stored in a database
`to facilitate the rapid retrieval of the recorded call at a
`later time.

`4.1 General Technical Overview
`
`Functional aspects of one embodiment of a machine
`executed method implementing an integrated telephony sys-
`tem for processing 9-1-1 calls for service is shown in FIG.
`2. The caller 100 makes a telephone call which is answered
`at a public safety answering point (PSAP) 105. The caller’s
`telephone number is decoded by the telephone PBX switch
`200 and passed to a computer 205. Computer 205 could be.
`for example. a Digital Equipment Corporation VAX 2100 or
`a personal computer.
`In the current embodiment of the invention. the caller
`identification is decoded from an in—band multifrequency
`(MF) signal by MF decoder cards inside the telephone PBX
`switch 200. One of ordinary skill will realize that the calling
`party identification information could be encoded in a dual
`tone multifrequency (DTMF). frequency shift keying (FSK).
`digital format. or the like. Each of these different encoding
`schemes would. of course. require its own decoding capa-
`bility in the telephone PBX switch 200.
`Assignment of the incoming call to a specific call-taker
`and the retrieval of the caller’s location information via the
`automatic location identification (ALI) controller 130 and
`remote database system (RDBS) 135 is done in a fashion
`similar to that described in the prior art system of FIG. 1.
`In accordance with the invention. each service provider
`(e.g.. Police. Fire. Emergency Medical Services. and other
`services) has installed one or more call processing units
`(215. 220. 22.5. and 230 respectively) which are imple-
`mented as clients (in a client/server computer environment)
`on a local area network (LAN) 210 and are dedicated to
`computer integrated telephony and supporting functions as
`described below. The host computer 205 functions as the
`network server. providing functional connectivity between
`the telephone PBX switch 205 and the call processing units.
`In general. the LAN 210 is used to transmit caller identifi-
`cation and location information to a service provider’s call
`processing unit. It is noted that the computer 205 could. in
`an alternative embodiment. be implemented as a plurality of
`computers. Additionally. the PSAP and service provides
`could be connected via a plurality of LANs. rather than a
`single LAN as shown in FIG. 2.
`When the PSAP call-taker wishes to transfer a 9-1-1 call
`to a service provider. the request is made via the appropriate
`call processing unit (e.g.. 215. 220. or 225) via the LAN 210
`to the host computer 205. The host computer 205 then issues
`appropriate instructions to the telephone PBX switch 200 to
`transfer the call. Call activity such as caller identification.
`caller location information. call routing information. and
`digital voice recording is captured and stored for later use.

`
`4.2 Human Factors Design
`Key features of a 9-1—1 calls for service system. in
`accordance with the claimed invention. are the ability to: (1)
`decrease the time required for an initial call-taker to transfer
`an incoming call to one or more service providers: (2) reduce
`line noise associated with analog circuit bridging: (3)
`decrease the time required for an initial call-taker to deter-
`mine the location of a mobile caller: and (4) integrate
`support functions such as digitized voice capture and stor—
`age. All of these attributes are associated with human factors
`aspects of a 9-1-1 calls for service system. In one embodi-
`ment of the invention. the human factors attributes cited
`above are addressed through a graphical user interface and
`touch-screen video display.
`FIG. 3 shows a display 300 that an initial PSAP call—taker
`would see prior to receiving a call. The screen display 300
`is divided into a number of fields (discussed in more detail
`below). in which icons are used to represent buttons. To
`select/invoke the function associated with a button.
`the
`call-taker touches the screen at a location corresponding to
`that button‘s graphical image. It will of course be realized
`that. depending on the ergonomic requirements of the
`system. the aforementioned touch-screen could be replaced
`by a standard video display and a graphical pointing device
`such as a “mouse” or function keys.
`The ANT/ALI field 305 is used to display information
`associated with the calling party and includes. but is not
`limited to. (l) identification or telephone number; (2)
`address; and (3) class of telephone service. e.g.. residential.
`business. coin phone.
`The call history field 310 may be used to display infor-
`mation about the current telephone number (when a call is
`incoming) such as the number of times the calling party
`number was used to access the 9-1-1 system during the past
`day. week. month. etc.
`The call processing functions field 315 are touch-screen
`buttons that implement a number of call processing func-
`tions. In the current embodiment these functions include
`connect. disconnect. hold. conference. and the like. similar
`to those found on ordinary digital telephone sets. The precise
`number of processing functions available can be directly
`related to the status of the call-taker. For instance. if the
`call-taker is waiting for a call. the only call processing
`function buttons available are “answer” and “deassign” as
`shown in field 315.
`
`The language conference field 320. in the upper-right
`hand corner of display 300. provides the call-taker with the
`ability to automatically route incoming calls to one or more
`foreign language agent groups. For instance. to transfer an
`incoming call to a Spanish speaking agent group. the call-
`taker simply touches the icon whose image represents the
`Mexican flag. Other foreign language agent groups are
`accessed via conferencing the AT&T “LANGUAGE-LINE”
`button.
`
`The speed-call field 325 contains screen buttons that are
`equivalent
`to programmable speed-dialing buttons on a
`typical digital telephone set. These buttons do not change as
`a function of call status but can be programmed to reflect the
`needs of the answering PSAP site. e.g.. social service
`agencies.
`The digital voice capture field 330 contains screen button
`controls to facilitate the capture. storage. and retrieval of
`digitized incoming calls. Button icons such as those found
`on ordinary VCR units are employed. In the current embodi-
`ment there is no button representing a record function as this
`feature is invoked automatically at the time an incoming call
`is received. For data security. permanent storage of digitized

`
`incoming calls can use optical write-once-read-many
`(WORM) disk units.
`4.2(a) Incoming Call
`When an incoming call arrives at a PSAP call-taker’s
`station. that call-taker's display is updated as shown in FIG.
`4.
`In addition to identification of the incoming calling
`number (see ANT/ALI field 305. call history field 310. and
`call processing functions field 315). a new selective routing
`field 400 is displayed.
`The selective routing field 400 is comprised of four icons.
`one for each currently supported service provider: Police.
`Fire. Emergency Medical Services. and Other. In the current
`embodiment the ‘Other’ icon is assigned to a Poison Control
`service provider. To aid the call—taker. distinctive icons
`representing each of the aforementioned service provides are
`used.
`
`To conference the call—taker. incoming caller and one or
`more service providers. the call-taker would touch the screen
`over the icon(s) representing the selected service provider
`(s). An important aspect of the invention is that the specific
`service provider contacted by the call-taker is a function of
`the calling party’s location. This feature is known in the art
`as selective routing.
`If the incoming call is conferenced to a service provider
`on the LAN 210.
`information about each call—taker
`is
`available for retrieval and can be displayed on the initial and
`service provider’s call-taker displays. Such information may
`include. but is not limited to. name. position number. and a
`digitized photographic image. See FIG. 5.
`Conferencing of additional agencies (i.e.. in addition to
`those represented by icons in the selective routing field 400)
`can be accomplished by selecting the appropriate button in
`the speed—call field 325.
`After the initial call—taker has conferenced the incoming
`call to one or more service providers the call-taker can. at his
`or her discretion. drop out of the conversation by completing
`the transfer. Call transfer is completed when the call-taker
`selects the “RELEASE” button in the call processing func-
`tions field 315. After transferring the call. the call-taker
`station becomes ready to receive another incoming call.
`4.2(b) Mobile Call Processing
`In prior art embodiments of 9-1-1 calls for service. the
`location of a mobile telephone caller is difficult to determine
`in that the call is generated by a radio transceiver with no
`known fixed location.

`
`In prior art 9-1-1 systems mobile relay stations. also
`known as cell sites. route 9-1-1 calls for service based on
`certain geographic factors impacting their radio coverage
`area and is typically accomplished by assigning a single
`telephone number (known as a trunk pilot number) from the
`PSTN. In these systems the 9— 1-1 call is routed to a PSAP
`depending on the trunk pilot number. This means that a
`legitimate (i.e.. a unique seven digit number representing the
`caller’s mobile telephone number) calling number is not
`available at the PSAP call-taker’s display. Thus. the call-
`taker must query the caller to determine their precise loca-
`tion and. with the aid of local street maps. determine which
`service providers should be notified. This need to use local
`maps is often a time consuming process and significantly
`impacts the quality and speed of 9-1-1 service that can be
`provided. Additionally. because the PSAP call-taker does
`not having a legitimate number with which to contact the
`caller.
`the call-taker cannot reestablish contact with the
`caller should the call become disconnected.
`
`45
`
`50
`
`55
`
`In the current embodiment of the invention. an incoming
`mobile call is routed directly from the call’s mobile tele—
`phone switching facility to a telephone PBX switch 200. The
`mobile telephone switching service transmits the call in
`digital format and includes data elements associated with the
`caller. These data elements may include. but are not limited
`to. a unique seven digit number representing the caller‘s
`
`65
`
`6
`mobile telephone number. identification of the mobile tele-
`phone company. and the unique identification of the origi-
`nating mobile relay or cell site.
`The unique caller identification number is displayed at the
`PSAP call-taker’s video display unit. A digitized map asso-
`ciated with the originating cell site identifier is also dis-
`played. As shown in FIG. 6. this allows the call-taker to
`identify the precise location of the caller by touching the
`screen corresponding to the location of the caller as it is
`communicated by the caller. Once the location of the caller
`is determined in this manner. the automatic selective routing
`fields 400 are automatically populated with the appropriate
`information based on the caller’s location. Additionally. a
`database consisting of streets and block ranges for the
`caller’s originating cell site coverage area is available for
`reference. Using this database the call-taker can also call up
`a digitized map.
`4.3 Some Benefits of the Invention
`Benefits of the claimed inventive method include:
`
`1. Reduce the connectivity time required to conference
`the call-taker. incoming caller and one or more service
`providers by 4 to 6 seconds.
`
`2. Reduce the time required for processing incoming
`mobile telephone calls by 30 seconds to 5 minutes.
`3. Increases the level of accuracy in the processing of
`9-1-1 calls for service by automating many of the tasks
`normally performed by a call-taker.
`4. Elimination of analog bridging noises associated with
`conference calling. Thus. the caller will not think they
`have been disconnected during the call transfer process.
`5. Digital capture of incoming voice and associated data
`of each call is automatic. The digitized data associated
`with each incoming call includes calling number. time
`and date of call. call duration. and call-taker identifi-
`cation.
`
`6. With the information associated with the digitized
`voice data. a database is made available which allows
`for quick and easy recall of past incoming calls. It
`should be noted that prior art tape recordings of incom-
`ing voice are often subpoenaed. It may take from
`several hours to several days to locate and copy a
`specified/target phone conversation. This time has been
`reduced to a matter of minutes by the method of the
`invention.
`
`7. The accumulation and processing of data associated
`with each received 9-1-1 call for service allows for
`statistical analysis and assists in personal and equip-
`ment management of the 9-1—1 calls for service system.
`8. The rapid. convenient. and automated routing of an
`incoming call from a nonEnglish speaking caller to an
`appropriate call-taker. e.g.. a call-taker who can effec-
`tively communicate with the non-English speaking
`caller.
`
`9. The graphical user interface environment utilized by
`the inventive method and the supporting process (e.g..
`automated routing. digital voice capture. etc.) drasti-
`cally reduces the complexity of the call-taker tasks.
`This.
`in turn. reduces the level of stress typically
`associated with the duties of a call-taker in a public
`safety emergency communication environment.
`It will be appreciated by those of ordinary skill having the
`benefit of this disclosure that numerous variations from the
`foregoing illustration will be possible without departing
`from the inventive concept described herein. Accordingly. it
`is the claims set forth below. and not merely the foregoing
`illustration. which are intended to define the exclusive rights
`claimed in this application program.
