Abstract: Methods and devices for enabling improved cell reselection procedures on a wireless communication device with a first SIM is camped on a serving cell of a first network may include receiving a list of neighbor cells from system information that is broadcast in the serving cell, and performing signal measurements associated with the listed neighbor cells and the serving cell, and, based on the signal measurements, identifying neighbor cells that satisfy selection criteria. The wireless device may calculate ranking criteria for the serving cell and the identified neighbor cells, and determine whether an inter-frequency neighbor cell has a highest ranking criteria among all of the ranked cells. Upon determining that an intra-frequency neighbor cell has the highest ranking criteria, the wireless device may start a reselection timer and also start decoding the system information that is being broadcast in the intra-frequency neighbor cell that has the highest ranking criteria.

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.
