Abstract: A method of reacquiring subscription service from a communication cell by a user equipment (UE) includes: during an active call in a dedicated channel (DCH) state, allocating one or more of a plurality of fingers of a rake receiver of the UE to decode a Master Information Block (MIB) value tag and System Information Blocks (SIBs) of an active set (ASET) of cell signals, and storing decoded SIB information and a value of the MIB value tag in a storage of the UE; when the active call is released, determining a cell having a strongest signal as a target cell for reacquisition, and comparing the stored value of the MIB value tag with a value of a broadcast MIB value tag; and if the value of the stored value of the MIB value tag is the same as the value of the broadcast MIB value tag, reading the SIB information of the target cell from storage of the UE, and reacquiring the target cell.
