Abstract: Provided is an apparatus and method for preventing successive failures in a call connection in a mobile communication terminal. When a call connection is attempted, a cell with the highest RX power is selected among cells and an RRC Connection Request message is transmitted from the mobile terminal to a BS of the selected cell. It is determined whether the mobile terminal receives an RRC Connection Accept/Reject message from the BS. If the mobile terminal receives an RRC Connection Reject message from the BS of the selected cell, it is determined whether the selected cell is able to perform the RRC connection by detecting a Connection Reject message frequency that is the number of times of rejection of an RRC connection request for a predetermined period. If the selected cell is not able to perform the RRC connection, a neighboring cell is reselected and an RRC Connection Request message is transmitted to the reselected neighboring cell.

Abstract: A method and apparatus for managing neighbor cells of a mobile communication terminal is provided. In the method, when a neighbor cell list is received from a network, neighbor cells are scanned to select a number of neighbor cells having high received signal strength indicator (RSSI) levels. The selected neighbor cells are managed in a BA list. The BA list is divided into a number of groups according to the RSSI levels. Different minimum signal strengths are applied to the respective groups, and it is determined whether there are neighbor cells that do not satisfy the minimum signal strengths. When the neighbor cells that do not satisfy the minimum signal strengths, the corresponding neighbor cells are deleted from the BA list.
