Apparatus and method for arbitration of updates provided to a universal integrated circuit card
Systems and methodologies are described that determine whether to communicate an update message to a UICC. A UE may be equipped a status update message from at least one of a first radio access technology (RAT) module supporting a first RAT and a second RAT module supporting a second RAT. The first RAT and the second RAT are different. Further, the UE may be equipped to determine whether to generate a universal integrated circuit card (UICC) update message to update a UICC by applying one or more RAT arbitration factors to the received status update message. The UICC includes current UICC status information associated with a current RAT. A status update message may include, a service status, RAT information, and location information, and the UE may apply the RAT arbitration factors to at least a portion of the status update message.
