Solutions that help save lives - eCall Routing and Dynamic Routing Control

In the event of a serious accident, rapid assistance to save human lives is, what really matters. Now, just a few minutes decide the fate of the accident victims. Are there witnesses who can dial 911 on their cell phones and describe the accident scene accurately? In the city, perhaps, but what about in the dark on a country road? For example, if you run into a tree because you tried to avoid collision with a deer.

When the airbags are released, the automatic emergency call system eCall (stands for Emergency Call) now provides fast, rescue assistance. Car manufacturers have to make eCall available in all newly registered cars and light trucks in the EU since March 2018. In the event of a serious accident eCall automatically sends information on the mobile network to a PSAP (Public Safety Answering Point) via the European emergency number 112. This way, rescue services and the fire departments can locate the exact position of an accident vehicle within seconds. In accordance with the EU Data Protection Directive, an eCall transmits only a minimum set of data (MSD): the time of the accident, the direction of travel, the vehicle class, and the type of fuel.

eCall routing from CreaLog creates more value for telcos

CreaLog supports telecom providers in the task of processing and routing eCalls including the related additional data in accordance with EU requirements in the respective 2G, 3G, 4G and 5G mobile networks.

Until now, the eCall modems that receive the alarm have often been located in the PSAP. CreaLog's eCall now brings this function directly into the telco's network. This allows the mobile operator to add more value and it also simplifies administration, as there is now no need to operate separate modems in each PSAP.

The CreaLog solution complements existing systems for country-specific emergency call routing with advanced functions for routing eCalls. Manual and automatic emergency calls from vehicles are received and the associated data in the voice signal is determined and evaluated via modem. The emergency call is then routed to the PSAP and the MSD is written to the emergency call database via a standardized interface, where they are permanently available to the PSAP via web services.

In addition to the actual emergency call service, it is also possible to use the eCall system for extended value-added services. Such services monitor the vehicle and obtain information from the vehicle that can be forwarded and used immediately.

Examples of possible applications:

  • Information for inspections or other maintenance services,
  • Information for special rates or premiums of car insurance,
  • Function as a black box to provide the police with insights into the course of the accident,
  • Localization of the vehicle after theft.

Beyond eCall solutions, CreaLog also supports classic emergency calls such as 110, 112, 113, 122 and many more.

Dynamic routing: No emergency call gets lost!

Personnel in regional PSAPs are quickly overloaded during major incidents. A solution is then needed that intelligently routes the excess calls to other regions with free capacities. Such a solution was already implemented for Swisscom in 2016 under the name Dynamic Routing Control (DLL). Here, too, the aim was to summon help quickly in an emergency. If there is a fire, someone has a circulatory collapse or a burglar is at the door, an emergency call should preferably always reach the nearest and most appropriate emergency control center.

Long wait queues are absolutely taboo in emergencies

In Switzerland and many European countries, there are a number of alternative emergency numbers for the police, fire department, ambulance service, children/youth emergency or telephone counselling in addition to the general emergency number 112. The official national languages of German, Italian and French also had to be taken into account. Consequently, a particularly intelligent and flexible solution was required to implement one of the most modern emergency call systems in Europe.

Innovative rerouting gets every caller to a destination

The Swisscom's telephone network now supports emergency call rerouting. If an emergency control center is unable to answer calls, the emergency call is immediately forwarded to another PSAP. Different overflow destinations can be stored in the rerouting plan for each emergency number and region. At the same time, call monitoring checks, whether the call is actually answered by another control center. If the next overflow destination is also unavailable, the callers end up at the Zurich Cantonal Police in a further escalation stage. This way, the intelligent CreaLog solution has been ensuring for years that no emergency call gets lost.
