| | Apparatus and a method for performing a call control in a mobile communication system - US Patent 6597909 |
 | | Based on the determining by the determination means, the overwrite means retrieves the subscriber data from the first storage and overwrites the retrieved data in a third storage area. | | | A visitor location register (hereinafter abbreviated to VLR) 2B of the present invention has a later-described function to access the MSC memory 12b and depending on examples, has a priority table (abbreviated to Pri Table in the figures) 23b, in addition to the function and construction of the conventional VLR 2A. | | | It is assumed here, for easy understanding, that the subscriber data area of the VLR memory 22b and the call connection information area in MSC memory 12b are equal in construction, i.e., in the number of bytes (constituting the area and the way of accessing the area. |

| | The Ki and RAND are fed into a standard A5 algorithm and a number called the Kc is calculated. | | | In practice, for performance reasons, most vendors integrate the VLR directly to the V-MSC and, where this is not done, the VLR is very tightly linked with the MSC via a proprietary interface. | | | The data stored in the VLR has either been received from the HLR, or collected from the MS. |
