In what are all conditions, MME execute cancel location procedure for an UE towards the HSS ?
If UE performs TAU due to new tracking area or due mobility from other RAT to eutran then new MME performs update location to HSS . now HSS performs cancel location with old MME/sgsn. Then HSS sends update location ack to new mme and MME sends TAU accept to UE .
In what all scenarios, this procedure gets executed ? And why this procedure need to be executed ?
Does anyone has an idea, after handover procedure when MME gets changed , target MME sends update location request to HSS ?
