20130219021 | PREDICTIVE CACHING FOR TELECOMMUNICATION TOWERS USING PROPAGATION OF IDENTIFICATION OF ITEMS OF HIGH DEMAND DATA AT A GEOGRAPHIC LEVEL - Method, computer program product and computer system for predictive caching for telecommunication towers having associated local servers, using propagation of identification of items of high demand data at a geographic level comprising the steps of: receiving within a region at least one request for an item of data made by a user device to a local server associated with a telecommunication tower within the region; and determining if the request is for an item of high demand data. If the item is identified as high threshold data, instructing the local servers within the region to cache the item of data; and if the item is identified as second threshold high demand data, sending an indication to at least one centralized server in an adjacent region, such that the centralized server in the adjacent region causes the local servers within the adjacent region to cache the item of data. | 08-22-2013 |
20150026826 | SUBSCRIBER IDENTITY MODULE-BASED AUTHENTICATION OF A WIRELESS DEVICE AND APPLICATIONS STORED THEREON - An approach is provided for performing a device-level and/or an application-level security check of a device. In the device-level check, a device hash is generated based on a subscriber identity module identifier (SIM ID), a device identifier, the number of secured applications, and the names of the secured applications. A temporary device hash is generated during a booting of the device. If the device hash is determined to not match the temporary device hash, the applications are removed from the device during the booting of the device. In the application-level check, an application hash is generated based on the SIM ID, the device identifier, and the application name. A temporary application hash is generated during a loading of the application. If the application hash is determined to not match the temporary application hash, the application is removed from the device without running the application. | 01-22-2015 |
