摘要： A security processing apparatus performs security processing in a MAC layer in a mobile communication system. The apparatus includes a mask generation unit generating a mask by using a security sequence number and a processing unit computing a logical operation on the mask and security target data to generate encrypted data. The security sequence number comprises a hyper frame number and a system frame number. The apparatus performs the security processing by using a transport block (TB) as one unit. The transport block is used as data transmission unit from a MAC layer to a physical layer per the unit time (TTI). Since HFN and SFN are used as the security sequence number, the security sequence number can be used uniformly over all RLC modes, and the out-of-synchronization of HFN can be avoided.

摘要： A base station includes a multicast group administration unit administering a multicast group to which a mobile station belongs, a timing determination unit determining an inter-frequency measurement timing when the mobile station measures a signal having a frequency different from a frequency for a residing cell of the mobile station, and a transmission unit transmitting data. The timing determination unit assigns an uniform inter-frequency measurement timing for at least two mobile stations belonging to the same multicast group. The transmission unit transmits data to a mobile station within the multicast so as to avoid the inter-frequency measurement timing.

摘要： A computerized method of compressing symbolic information organized into a plurality of documents, each document having a plurality of symbols, includes: (i) automatically identifying a plurality of sequential and non-sequential symbol pairs in an input document; (ii) counting the number of appearances of each unique symbol pair; and (iii) producing a compressed document that includes a replacement symbol at each position associated with one of the plurality of symbol pairs, at least one of which corresponds to a non-sequential symbol pair. For each non-sequential pair the compressed document includes corresponding indicia indicating a distance between locations of the non-sequential symbols of the pair in the input document. In some instances the plurality of symbol pairs includes only those pairs of non-sequential symbols for which the distance between locations of the non-sequential symbols of the pair in the input document is less than a numeric distance cap.

摘要： A computerized method and apparatus compresses symbolic information, such as text. Symbolic information is compressed by recursively identifying pairs of symbols (e.g., pairs of words or characters) and replacing each pair with a respective replacement symbol. The number of times each symbol pair appears in the uncompressed text is counted, and pairs are only replaced if they appear more than a threshold number of times. In recursive passes, each replaced pair can include a previously substituted replacement symbol. The method and apparatus can achieve high compression especially for large datasets. Metadata, such as the number of times each pair appears, generated during compression of the documents can be used to analyze the documents and find similarities between two documents.
