Abstract: A method of handling queries caused overload in a core network of a wireless communication is disclosed. The core network comprises a data base and a network control node which stores a mobility management (MM) context of a mobile device. The method comprises the network node sending information in a notification message to the data base, wherein the information comprises at least one of International Mobile Subscriber Identity (IMSI), UE Reachability Request Parameter for the MME/SGSN (URRP-MME/URRP-SGSN), and a session management (SM) and/or mobility management (MM) back-off timer or a back-off indicator.
