When an IP-based emergency call is initiated a rich set of data from When an IP-based emergency call is initiated, a rich set of data from
multiple data sources is conveyed to the Public Safety Answering multiple data sources is conveyed to the Public Safety Answering
Point (PSAP). This data includes information about the calling party Point (PSAP). This data includes information about the calling party
identity, the multimedia capabilities of the device, the emergency identity, the multimedia capabilities of the device, the emergency
service number, location information, and meta-data about the sources service number, location information, and meta-data about the sources
of the data. The device, the access network provider, and any of the data. The device, the access network provider, and any
service provider in the call path may have even more information service provider in the call path may have even more information
useful for a PSAP. This document extends the basic set of data useful for a PSAP. This document extends the basic set of data
communicated with an IP-based emergency call, as described in communicated with an IP-based emergency call, as described in
[RFC6443] and [RFC6881], in order to carry additional data which may [RFC6443] and [RFC6881], in order to carry additional data which may
be useful to an entity or call taker handling the call. This data is be useful to an entity or call taker handling the call. This data is
"additional" to the basic information found in the emergency call "additional" to the basic information found in the emergency call
signaling used. signaling used.
In general, there are three categories of data communicated in an In general, there are three categories of this additional data that
emergency call: may be transmitted with an emergency call:
Data Associated with a Location: Location data is conveyed in the Data Associated with a Location: Primary location data is conveyed
Presence Information Data Format Location Object (PIDF-LO) data in the Presence Information Data Format Location Object (PIDF-LO)
structure originally defined in RFC 4119 [RFC4119] and extended by data structure as defined in RFC 4119 [RFC4119] and extended by
RFC 5139 [RFC5139] and RFC 6848 [RFC6848] (for civic location RFC 5139 [RFC5139] and RFC 6848 [RFC6848] (for civic location
information), RFC 5491 [RFC5491] and RFC 5962 [RFC5962] (for information), RFC 5491 [RFC5491] and RFC 5962 [RFC5962] (for
geodetic location information), and geodetic location information), and
[I-D.ietf-geopriv-relative-location] (for relative location). [I-D.ietf-geopriv-relative-location] (for relative location).
There may be data that is specific to the location not available This primary location data identifies the location or estimated
in the location data structure itself, such as floor plans, tenant location of the caller. However, there may exist additional,
and building owner contact data, heating, ventilation and air secondary data which is specific to the location, such as floor
conditioning (HVAC) status, etc. plans, tenant and building owner contact data, heating,
ventilation and air conditioning (HVAC) status, etc. Such
secondary location data is not included in the location data
structure but can be transmitted using the mechanisms defined in
this document; although this document does not define any
structures for such data, future documents may do so following the
procedures defined here.
Data Associated with a Call: While information is carried in the Data Associated with a Call: While some information is carried in
call setup procedure itself (as part of the SIP headers as well as the call setup procedure itself (as part of the SIP headers as
in the body of the SIP message), there is additional data known by well as in the body of the SIP message), there is additional data
the device making the call, and the service provider along the known by the device making the call and/or a service provider
path of the call. This information may include the service along the path of the call. This information may include the
provider contact information, subscriber identity and contact service provider contact information, subscriber identity and
information, the type of service the service provider and the contact information, the type of service the service provider and
access network provider offer, what kind of device is being used, the access network provider offer, what type of device is being
etc. Some data is device or service dependent data. For example, used, etc. Some data is broadly applicable, while other data is
a car telematics system may have crash information. A medical dependent on the type of device or service. For example, a
monitoring device may have sensor data. medical monitoring device may have sensor data. The data
structures defined in this document (Data Provider Information,
Device Information, and Owner/Subscriber Information) all fall
into this category ("Data Associated with a Call").
Data Associated with a Caller: This is personal data about a caller, Data Associated with a Caller: This is personal data about a caller,
such as medical information and emergency contact data. such as medical information and emergency contact data. Although
this document does not define any structures within this category,
future documents may do so following the procedures defined here.
This document only defines data structures relevant to data While this document defines data structures only within the category
associated with the call but defines extension points for other data of Data Associated with a Call, by establishing the overall framework
to be added via other specifications. of Additional Data, along with general mechanisms for transport of
such data, extension points and procedures for future extensions, it
minimizes the work needed to carry data in the other categories.
Other specifications may make use of the facilities provided here.
For interoperability, there needs to be a common way for the For interoperability, there needs to be a common way for the
information conveyed to a PSAP to be encoded and identified. information conveyed to a PSAP to be encoded and identified.
Identification allows emergency services authorities to know during Identification allows emergency services authorities to know during
call processing which types of data are present and to determine if call processing which types of data are present and to determine if
they wish to access it. A common encoding allows the data to be they wish to access it. A common encoding allows the data to be
accessed. successfully accessed.
This document defines the data structures and a way to communicate This document defines an extensible set of data structures, and
the information in several ways. Although current standardization mechanisms to transmit this data either by value or by reference,
efforts around IP-based emergency services are focused on the Session either in the Session Initiation Protocol (SIP) call signaling or in
Initiation Protocol (SIP) and HTTP the data structures in XML format the Presence Information Data Format Location Object (PIDF-LO). The
described in this document are usable for other communication systems data structures are usable by other communication systems and
as well. In Section 3 the data structures are defined and the SIP/ transports as well. The data structures are defined in Section 3,
HTTP transport components are defined in Section 4 to offer a clear and the transport mechanisms (using SIP and HTTPS) are defined in
separation between the two. Section 4.
More technically, the data structure described in this document is Each data structure described in this document is encoded as a
represented as one or more "blocks" of information. Each of the "block" of information. Each block is an XML structure with an
blocks is an XML structure with an associated Multipurpose Internet associated Multipurpose Internet Mail Extensions (MIME) type for
Mail Extensions (MIME) type for encapsulation, and an extensible set identification within transport such as SIP and HTTPS. The set of
of these types constitute the data set. A registry is defined to blocks is extensible. Registries are defined to identify the block
list the block types that may be included. types that may be used and to allow blocks to be included in
emergency call signaling.
