For the purposes of the present document, the following terms and definitions apply:

access network: portion of the telecommunications network that provides access to the switching function and

Access Network Provider (ANP): service provider that provides physical and IP connectivity to a user equipment

NOTE: The access network may be provided by a single organization or it may be provided by a number of

different organizations, BUT the interfaces between these organizations are not relevant to the scope of

the present document as it is matter of contractual relations between the parties.

default PSAP: PSAP that is routed to when insufficient information exists to route to a specific PSAP, based on either

emergency call: call from a user to an emergency call centre, PSAP or similar agency charged with routeing calls to the

emergency call facilities: mechanisms provided by public or private communications networks, emergency telephone

stanchions/boxes, fire alarms, etc. the use of which enables emergency calls to be made

Emergency Call Service Provider (ECSP): service provider that acts as a mediator between the voice service

emergency caller: individual placing an emergency call to reach the suitable PSAP

NOTE: Examples of emergency service types are ambulance, police, fire brigade, etc.

emergency response organization: local or national force established to provide assistance to citizens in the event of

emergency service: service that provides immediate and rapid assistance in situations where there is a direct risk to life

or limb, individual or public health or safety, to private or public property, or the environment but not necessarily

emergency situation: abnormal situation of serious nature that develops suddenly and unexpectedly, of which the

evolution is uncertain and which may turn into a crisis or cause damage and casualties

Location-by-Reference: representing location information indirectly using a location URI

Location-by-Value: using location information in the form of a location object (LO), such as a PIDF-LO

NOTE: A location value can be obtained from a location identifier by applying a static mapping or the location

identifier may be encoded in such a way that it contains a location value (e.g. a ZIP code).

location information: location value, and/or a location identifier and/or a location reference

location reference: identifies a location server and provides sufficient information to allow the location server to

location URI: identifier that serves as a reference to location information which is later used as input by a dereference

network-provided location information: any location information pertaining to the calling device that is determined,

Next Generation Network (NGN): packet-based network able to provide telecommunication services and able to

make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are

NOTE: A nomadic user can make calls from different locations. However, unlike a mobile user, the location of a

PSAP Service Provider (PSP): service provider that provides connectivity to Public Safety Answering Points (PSAPs)

Public Safety Answering Point (PSAP): physical location where emergency calls are received under the responsibility

telecommunication: any transmission, emission, or reception of signs, signals, writing, images, sounds or intelligence
