`
`Executive Summary
`The TR45 Joint Experts Meeting (JEM) on Public 800 Mobile and
`Personal Communications Support of Basic 9-1-1 (9-1-1) and Enhanced
`9-1-1 (E9-1-1) Emergency Services was held in Chicago. IL. The JEM
`was convened on August I. 1994 at 9:07 AM and was adjourned on August
`5. 1994 at 1l:47AM. Terry Jacobson (AT&T) was the chair and Jeff
`Crollick (GTE) was the co-chair.
`
`The purpose of the JEM was to:
`
`• Derme and prioritize the Emergency Services call taker features for
`Wifeless cellular,
`• Define tbe requirements for the information flow between the
`Wireless System and the Public Safety Answering Point (PSAP), and
`to associate this infonnation flow with the 9-1-1 call by the Mobile
`Station (MS). MS is a collective term that includes vehicular,
`portable, transportable, ftxed, aircraft and other wireless subscriber
`stations.
`
`The outcome of the JEM was:
`
`• A prioritized list of Emergency Services call taker features.
`The mapping of the call faker features to four evolutionary paths:

`Introduction
`
`Background
`
`2.
`
`2.1
`
`The basic 9-1-1 (9-1-1) and Enhanced 9-1-1 (E9-1-1) systems in existence
`today have been designed to provide rapid response to calls for emergency
`services from wireline subscribers. Basic 9-1-1 Emergency Services
`Systems establish routing of calls to a Public Safety Answering Point
`(PSAP). E9-1-1 provides added capabilities including selective routing of
`a call to the appropriate PSAP for rapid response to emergency calls and
`the display of calling number, address, and in most cases. the name of the
`subscriber at the calling number. However, these Emergency Services
`Systems do not address the unique characteristics of wireless
`communications.
`
`The mobile nature of wireless communications and the uniq.ue
`characteristics of Radio Frequency (RF) propagation may requue
`modification of existing Emergency Services Systems and the
`development of special capabilities in wireless systems.
`
`Emergency services access (9-1-11E9-1-l) by a wireless caller requires
`that the MS location information (at least the serving cell site or sector) be
`used to assist in routing the call to the appropriate PSAP. The location
`information may be used to dispatch an emergency vehicle to the incident
`site.
`
`2.2
`
`Perspective
`The views expressed in this report represent an evolutionary path. The
`public safety and cellular service provider communities each have a
`unique set of challenges that includes economic, operational and
`technological feasibility. These factors should be considered in the use of
`this report.
`
`2.3
`
`JEM·Methoctology
`
`Tutorials were presented on Mobility, Emergency Services, Current
`Ind..-y Practices, 1R4~ Standards, and Emergency Services for Wireless
`Cellular. The tutorials established a common frame of reference and
`terminology for the JEM participants.
`
`The tutorials and contributions provided a basis for discussion of:
`
`•
`•
`
`Call taker features and feature priorities.
`Information flows between the Wireless System and the Emergency
`Services System.

`
`Radio location techniques that may provide more accurate Mobile
`Station location information.
`A prioritized list of call taker features was generated. The list was
`reviewed and the features were mapped to the four evolutionary paths.
`
`The flow of information needed between the Wireless System and the
`Emergency Services System to support the call taker features was
`identified. Information elements were identified and information flow
`models were defined.

`E9-1-1 Call Taker Fellture Priority
`
`Call Taker Feature Descriptions
`
`The following is a list of call taker features and a high level description
`and requirements. The list is in priority order.
`
`1.
`
`Emergency services Reached by 018.ng [!I-m-ITJ-IsENol
`
`•
`
`•
`
`A Mobile Station user dialing ~{~]-[TI-lSENDI shall access
`Emergency Services.
`
`r:J-~-ITJ-CD-lsENDI should be treated as a 9-1-1 call. (This non(cid:173)
`preferred sequence should not be publicized.)
`
`•
`
`•
`
`Dialing ~-[D-[D-l SENDl shall bypass other call origination restriction
`features (e.g., PIN access, PIN intercept).
`A Mobile Station may have an emergency service or 19-1-11 call button
`to speed dial the ~-G] -CD-I SENDIsequence.
`• Mobile Stations should allow ~'ITI-ITI-1 SENDl
`to be dialed at all
`times (even when locked or when served by a restricted system).
`
`2.
`
`9-1-1 eatl PNCedence
`
`•
`
`•
`
`An originating 9-1-1 call should be given priority over other non(cid:173)
`emergency call originations.
`
`The alternate Priority Access and Channel Assignment (All. PACA)
`procedures described in PN-2977 (the proposed IS-53A Cellular
`Feature Descriptions) provides an interim solution for precedence of
`9-1-1 calls:
`
`three levels of priority are established designated A, B, and C.
`
`a number of channels are reserved for A (highest), Band C
`(lowest) priority calls.
`
`a caller with "A" priority has access to the A, B, C channels.
`a caller with "B" priority has access to the B, C channels.
`a caller with "c' priority has access to the C channels.
`a 9-1-1 call may be treated as a priority call subject to local
`operating practices or regulations.
`
`•
`
`Priority Queuing could be considered as another mechanism to
`provide access for an emergency call. If a traffic channel is not
`available when the Mobile Station user attempts to originate the 9-1-1
`
`E9-1-1 Call Taker Feature Priority

`
`call. the call would be "queued" and the Mobile Station would be
`paged and alerted when a radio channel becomes available.
`Future 800 MHz air interface standards should support the Priority
`Access and Channel Assignment (PACA) feature defmed in PN-2977
`(the proposed IS-53A Cellular Feature Descriptions).
`
`•
`
`3.
`
`Identify c.u.'s Initial location
`
`•
`
`• Obtaining location information shall not require overt action on the
`part of the caller.
`The method of sending location information from the Wireless
`System to the Emergency services System shall be standardized. The
`location infonnation should describe the Mobile Station's position in
`tenns of:
`Longitude.
`Latitude.
`Altitude.
`Resolution or Accuracy.
`Location information should be obtainable for all callers.
`
`•
`
`• Accuracy Goals: 1
`Near tenn goal: within 400 feet (longitude, latitude, resolution).
`Long tenn goal: within 40 feet (longitude, latitude, altitude,
`resolution).

`• Mobile Stations should allow the caller to initiate a 9-1-1 call when
`the Mobile Station's programming prevents it from accessing the
`system for other wireless services.

`
`Impact of Call Taker Feature Priority
`
`The amount of changes required to implement a particular feature were
`analyzed to detennine if the changes required are:
`
`Existing:
`
`No change to existing equipment or protocols.
`
`Expanded: Minor changes to existing equipment or protocols.
`
`Enhanced: Major changes to existing equipment or protocols.
`The chances were analyzed for the wireless ~llular system (the Home
`Location Register. the Visitor Location Register, the Mobile Switching
`Center, and other required functions), Mobile Stations, and the 9-1-1 and
`E9-1-1 systems (selective routers, PSAPs. etc.).
`
`The changes and the degree of the changes were applied to select a
`particular migration path as shown in the ronowing table:

`
`The emergency service call is made over a CAMA trunk. The 7 (or 8)

`
`CAMA with Subscriber Specific Pseudo ANI
`
`The emergency service call is made over a CAMA trunk. The 7 (or 8)
`digits of ANI information are used to convey a pseudo ANI. The pseudo
`ANI is usually used to identify the caller's serving cell (or sector) and the
`caller. The caller's identity is temporary, but it allows other information to
`be correlated. For instance, a directive could be used to convey specific
`information about the call (caller identification information, location
`information, etc.) This information may be correlated using the pseudo

`
`Call Setup with Additional Information
`
`The emergency service call is made over a ISUP (ISDN (Integrated
`Services Digital Network) User Part) trunk modified to carry additional
`information about the call (caller identification information,
`location
`information, etc.). This method for information transfer is direct and does
`not require correlation of other messages. ISUP may not have sufficient
`bandwidth for the intended information flow and ISUP does not have
`procedures for additional messages to request and deliver location
`information.

`
`Call Setup with Additional Information
`
`The emergency service call is made over a C~"1A trunk. The 7 (or 8)
`digits of ANI infonnation are used to convey a pseudo A;....1. The pseudo
`ANI is usually used to identify the caller's serving cell (or sector) and the
`caller. The caller's identity is temporary, but it allows other infonnation to
`be retrieved. For instance, more information may be requested that could
`be used to convey specific infonnation about the call (caller identification
`information, location infonnation, location updates. etc.).

`
`Information Element Locations
`Note: reference points and network elements not gennain to emergency
`service infonnation element sources have been excluded for the sake of
`clarity. ANI refers to a full IO-digit (or greater) identification of the calling
`subscriber. ANI7 refers to a restricted 7- and 8-digit At'll.
`
`The A. B, O. Urn, OJ, and Ai are existing interfaces.
