Abstract: A method and system for creating, reading and writing compressed files for use with a file access storage. The compressed data of a raw file are packed into a plurality of compressed units and stored as compressed files. One or more corresponding compressed units may be read and/or updated with no need for restoring the entire file whilst maintaining de-fragmented structure of the compressed file.

Abstract: For use in a storage network comprising a plurality of network elements and operable with a block mode access storage protocol, a method of operating a compression system operatively coupled to at least one computer and to one or more storage devices configured as at least one storage logical unit accommodating data compressed by the compression system, the computer, the storage devices and the compression system are configured as separate network elements. According to the method, the compression system is configured to hold a virtual logical unit, the virtual logical unit is configured to virtually represent in non-compressed form the compressed data stored in the at least one storage logical unit. The size of the virtual logical unit corresponds to an estimated size of raw data which, being compressed, would substantially amount to a size of the storage logical unit.

Abstract: A method and system for automatically placing calls made from a mobile telephone in an economical manner via calling card and call-back programs, with minimal user overhead. The system may be installed on an existing telephone by the user. To operate, the user initiates the placement of a call in the regular manner, as if the call were placed directly, and the system automatically places the call in the most economical way, such as via calling card or call-back program. The user can employ any dialing conveniences offered by the mobile telephone, including “speed dialing”, “phone book” dialing, or recent call dialing. All interaction with the calling card/call-back server is handled automatically; the user need not be aware that the call is being placed via a calling card or call-back program. Additional automatic features include automatic calling card recharging and selection of SIM for telephones supporting multiple SIM's.

Abstract: A method and system for creating, reading and writing compressed data for use with a block mode access storage. The compressed data are packed into plurality of compressed units and stored in a storage logical unit (LU). One or more corresponding compressed units may be read and/or updated with no need of restoring the entire storage logical unit whilst maintaining de-fragmented structure of the LU.

Abstract: A method and system for creating, reading and writing compressed files in a computer system comprising a file system coupled with storage medium and at least one application program interface (API) configured to communicate with the file system by means of file access-related requests. The file access-related requests are intercepted in order to provide at least one of the following: a) to derive and compress data corresponding to the intercepted file access request and to facilitate storing the compressed data at the storage medium as a compressed file; b) to facilitate restoring at least part of compressed data corresponding to the intercepted file request and communicating the resulting data through the API. The compressed files comprise plurality of compressed units. One or more corresponding compressed units may be read and/or updated with no need of restoring the entire file whilst maintaining de-fragmented structure of the compressed file.
