Title: IMPROVED SUBSCRIPTION ACQUISITION TIME
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 state, allocating one or more of a plurality of fingers of a rake receiver to decode a Master Information Block (MIB) value tag and System Information Blocks (SIBs) of an active set of cell signals, storing decoded SIB information and the MIB value tag value in 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 MIB value tag value with a value of a broadcast MIB value tag; and if the value of the stored 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.
