A METHOD AND DEVICE FOR TRIGGERING SERVICE LOGIC EXECUTION RECORDING FOR A CALL BETWEEN A CALLING USER EQUIPMENT, UE, AND A CALLED UE IN A TELECOMMUNICATION NETWORK

A method for triggering service logic execution recording of a call between a calling User Equipment, UE, and a called UE in a telecommunication network, wherein said service logic execution recording is to be triggered by nodes in a chain of nodes involved in establishing a call between said calling UE and said called UE, wherein said method comprises the step of inserting in a call establishment message, a service logic execution recording parameter, wherein said parameter indicates that nodes involved in said establishing of said call between said calling UE and said called UE should perform service logic execution recording, wherein said service logic execution recording is any of recording of log files and recording of trace files reflecting signalling between said nodes in said chain.
