Patent ID: 8000705

Claim:
A method for preventing successive failures in a call connection in a mobile terminal, the method comprising the steps of: selecting a cell with a highest reception power among cells and transmitting a Radio Resource Control (RRC) Connection Request message to a base station (BS) of the selected cell when a call connection is attempted; determining whether the mobile terminal receives an RRC Connection Reject message from the BS; updating a recorded number of RRC Connection Reject messages received during a current predetermined period and comparing the recorded number with a predetermined maximum rejection frequency, when the mobile terminal receives the RRC Connection Reject message from the BS of the selected cell; reselecting a neighboring cell and transmitting an RRC Connection Request message to the reselected neighboring cell, when the recorded number is greater than the predetermined maximum rejection frequency; and changing the mobile terminal to an idle state, when the recorded number is less than or equal to the predetermined maximum rejection frequency.
