Abstract
A method and apparatus for allowing an Authentication Center (AC) in a cellular telephone system to order SSD update and unique challenge operations only if the receiving MSC/VLR is receptive to performing them. The AC has access to an MPCM file that indicates the circumstances under which each MSC/VLR in the system will perform SSD updates and unique challenges. Thus, whenever the AC determines that it is desirable to send either an SSD update or a unique challenge, the AC first checks the MPCM file to determine whether the message should be sent. If the database indicates that the MSC/VLR will not attempt the operation, the AC does not request the operation.
