Examples of PIDF-LO in a sentence

  • The SIP interface can be used for carriers delivering i3 compliant interface with PIDF-LO or ESInet to ESInet call hand-offs and transfers.

  • There is no mechanism for transferring the PIDF-LO or the Emergency Incident Data Document (EIDD) to exchange location data and any other supplemental data or alternatively URIs to the dereferencing systems that would provide the data or data updates to the PSAP.

  • The ESRP processes ingress calls received using Session Initiation Protocol (SIP) signaling with location embedded in the Presence Information Data Format – Location Object (PIDF-LO) from i3-compliant carrier networks, from legacy carriers or from selective routers via the Legacy Selective Router Gateway (LSRG) and routes calls to the call processing system (CPS) and then on to the PSAP location, according to the caller’s location and the PSAP-configured routing policy.

  • Call transfers between i3 PSAPs will support additional information, such as PIDF-LO, and depending on CPE, case notes and TTY.

  • PIDF-LO is a SIP message that has location information embedded in an XML format within the SIP invite.

  • The NIF will generate the SIP PIDF-LO (Presence Information Data Format-Location Object).

  • This includes the ability for the call handling system to query the ECRF to obtain specific information about which Police, Fire, and EMS supports the caller location, based on the GIS information received within the PIDF-LO message.

  • When the ESRP receives an ingress call, it evaluates the SIP INVITE geolocation header within the PIDF-LO.

  • Location may be conveyed to the system that performs the selective routing function in the form of ANI or pseudo-ANI associated with a pre-loaded ALI database record (in Legacy 9-1-1 systems), or in real time in the form of a Presence Information Data Format – Location Object (PIDF-LO) (in NG9-1-1 systems) or whatever forms are developed as 9-1-1 continues to evolve.

  • In the event a CSI PSAP requires the use of selective transfer functions, the Host 911 System sends the call with the proper agency identified in the PIDF-LO + Service URN to the INdigital ESInet based ESRP.
