In the course of their transition to NGN and IMS networks, telecommunications companies are faced with the challenge of implementing all the requirements specified by ETSI and ITU according to regulatory requirements for emergency calls. The CreaLog Emergency Service Control Point is a proven application framework that supports communication service providers in meeting these requirements. The ESCP can be connected to both worlds. It links to any customer database and will interact with location based server platforms (LBS) of any kind. This functional entity handles the retrieval of location information from the location server or database. This includes, where required, interim location information, initial location information, and updated location information. The ESCP interacts with the integrated location based routing entity to determine which emergency call center to forward the call to. Forwarding location position information
A main purpose of the PSAP is to obtain more accurate or updated location position information of the emergency case during or after the emergency call where required by local regulations. The location information forwarding system can provide this functionality for both worlds, PSTN and NGN/IMS networks. So in both cases, this information can be passed on to the emergency call center. If calls are forwarded from the emergency call center to medical or fire call centers, the location information for this emergency case can be forwarded to the final call center as well.
In future, all communication (voice, video, and text) will be based on SIP. So to simplify the task of other emergency organizations involved in handling emergency calls, CreaLog recommends to all organizations taking part in the emergency case process to switch over to SIP based communications for all media.
