Notruf is an single emergency line for German networks that uses geolocation to collect and store a caller's information. The information collected includes party location and call center location/numbers. Notruf uses Ribbon SBC call processing to collect information from the caller. 

Within this context, the primary objectives of this feature is to insert calling party location information, and to provide a dialed emergency number translation (if needed) for emergency calls within German networks.

The SBC is deployed in customer networks as a Centralized Policy Server (CPS). The SBC Core supports the mandated German emergency call concept requirements, as follows:

  • Location database for all subscriber numbers in the customer network.
  • Association of the stored location information with an emergency call setup and generate the location information signaling parameter in the egress emergency call request. The SBC uses an ISUP UUI parameter encoded in accordance with ITU-T Recommendation Q.763/Q.931 and “TR Notruf” Technical Directive on Emergency Calls to carry the location information to the Public Safety Answering Point (PSAP).
  • Translates dialed emergency number 110 or 112 to the corresponding PSAP address.
  • Routes the call accordingly through the customer network.

The hold the administrative area(AGS_N and GF) associated mapping of Emergency number with PSAP number
Subscriber table will hold the location information and as well as administrative area(AGS_N and GF) of the of the subscriber. The AGS_N and GF of subscriber refers to the PSAP tables AGS_N and GF.

The PSAP Profile is added to the CLI. This PSAP profile is used to configure a PSAP Table.

Command Syntax

The following command is used to create the PSAP Profile.
