Abstract
A system with a mobile switching center (MSC), a service control point (SCP) and an emergency center (EC). The mobile switching center (MSC) sets up a call between a mobile station (2(i)) and the emergency center (EC), sends first data including raw location data as to where the mobile station (2(i)) is located to the emergency center (EC), and sends a service invocation to the service control point (SCP) to invoke an Intelligent Network service to start searching for second data relating to the mobile station, including more accurate location data as to where the mobile station is located. The service control point (SCP) receives the service invocation, starts the Intelligent Network service to search for the second data and sends the second data to the emergency center (EC) once said second data becomes available.
