NG112 & eCall
Telco
NG112 emergency call routing and network-based eCall for carriers: CreaLog combines central location logic, fallback routing and multimodal emergency call communication into a telco-grade emergency service architecture.
Emergency call communication for voice, IMS and IP networks
NG112 is the European standard for IP-based emergency calls. CreaLog modernises emergency call communication in voice, IMS and IP-based emergency service environments – with central routing and location logic, verification of technical and organisational requirements, and integration into existing control centres (PSAP).
Location-based emergency call routing
The emergency call reaches the right control centre
The CreaLog routing solution takes into account the caller’s location, geographic responsibilities and the availability of the connected control centres. Location information is retrieved from a Location Information Server (LIS) and matched against the defined Public Safety Answering Point (PSAP) and service boundaries.
Standardised procedures such as HELD and LoST support the provision and assignment of location data. On this basis the Emergency Services Routing Proxy can forward the emergency call to the matching PSAP.
Supra-regional and cross-border routing scenarios can also be accommodated within the architecture.
Fallback routing, overload control and availability
Emergency call routing must remain stable even when individual PSAPs are technically unreachable, organisationally unavailable or temporarily overloaded. Availability is therefore checked before handover, and routing is redirected to alternative destinations on a policy basis where required. This avoids lost or misrouted emergency calls and keeps operating models under control even under load.
Defined routing profiles and announcements additionally support the handling of exceptional situations. For known major events, standard announcements can be used to inform callers proactively and to reduce misdirected or duplicate calls.
Prevention of lost or misrouted emergency calls
Controlled handling of overflow and busy cases
Higher reachability in exceptional situations
Clean separation of routing logic and local PSAP processing
eCalls handled centrally in the network
Connecting eCall112 and NG-eCall across several network generations
During an eCall the vehicle transmits a Minimum Set of Data (MSD) while the voice connection is active containing the location and further vehicle information.
The network-based eCall solution from CreaLog supports classic eCall112 calls from 2G and 3G networks as well as NG-eCall from IMS-based 4G and 5G networks. Communication with the vehicle system is processed centrally in the network, and the emergency call is then routed to the responsible control centre.
Location and vehicle data are provided via the Location Information Server (LIS) and retrieved there by the control centre.
Central eCall processing for 2G/3G as well as IMS, 4G and 5G scenarios
Decoupling of regional PSAPs from local eCall-specific equipment
Standards-aligned provision of MSD and location data
Simplified operation, rollout and service restoration
Accessible emergency communication beyond voice
Emergency calls and real-time text
Real-Time Text (RTT) transmits typed text immediately and can be used in parallel with an active voice connection in the telephone network. The CreaLog NG112 solution routes RTT emergency calls to the control centre.
This makes it easier in particular for deaf, hard-of-hearing and deafblind people to communicate with a control centre, and in emergency situations in which speaking is not possible. An integrable conference function can additionally support follow-up questions and bringing in further emergency personnel.
Recording and transcription
Documenting emergency communication verifiably
Optionally, emergency communication can be recorded centrally within the ESInet and stored encrypted. Depending on the connected environment, text, location information and further session data can be captured alongside voice.
Recording and transcription can support later analysis, quality assurance and the reconstruction of an incident. The specific implementation depends on the applicable legal and organisational requirements.
NG112 building blocks
Carrier-grade platform expertise and experience in fixed, mobile, SIP and IMS environments for highly available, regulated communication environments.
NG112 and eCall at carrier-grade level
Location logic, routing and eCall from one platform instead of scattered point solutions.
Modular architecture
Routing, eCall processing, location services, real-time text and recording can be combined to suit the existing infrastructure. Existing systems and partner components can be integrated via defined interfaces
Secure integration
Standards-aligned integration into existing network and control centre environments. The architecture allows step-by-step modernisation. Network operators can continue to use existing components and add new NG112 functions where needed.
High availability
Redundant operating models, monitoring and flexible routing and fallback logic support the stable operation of business-critical and safety-critical emergency services.
