Abstract:
A method for emergency call handling for a User Equipment (UE). A UE performs a first emergency call. The UE also transmits a first UE location report. Furthermore, the UE performs a second emergency call. The UE re-transmits the first UE location report when it is determined that a change in a UE location (since the transmission of said first UE location report) is below a threshold value. Alternatively, the UE re-transmits the first UE location report when it is determined that a time period set by a timer has not expired, wherein the time period set by this timer is set upon transmission of the first location report. Otherwise, the UE transmits a second UE location report.
