摘要： A system and method by which an unnecessary General Packet Radio Service (GPRS) attach procedure is no longer performed when a service cancellation situation is generated during execution of a GPRS attach procedure according to a data service requested by a user is provided. The system determines whether an abnormal situation occurs in an Europe-oriented General Packet Radio Service/Universal Mobile Telecommunication System (GPRS/UMTS) mobile terminal and immediately terminates a currently proceeding attach procedure when an abnormal service cancellation situation occurs. The abnormal situation occurs when the user cancels a service during use of a data service (e.g., Wireless Application Protocol (WAP), Multimedia Message Service (MMS)) or when connection of the service fails due to a bad network state. By not performing an unnecessary GPRS attach procedure due to the occurrence of an abnormal situation, the mobile terminal does not perform an unnecessary routing area updating procedure, thereby reducing power consumption.
