  • Patent number: 7739276
    Abstract: A photo retrieval method, system, and medium using multimodal information which prevents a photo of an irrelevant category to be retrieved having a high ranking due to an unfavorable side effect from a query expansion, by reflecting a level of consistency between an object category of a query and a category of a photo retrieved by expansion retrieval using ontology, to a photo retrieval result ranking is provided. The photo retrieval method using the multimodal information includes: assigning an object category with respect to a query; retrieving photos associated with an expanded query term extracted from the query; determining a ranking of the retrieved photo by reflecting the assigned object category; and arranging and displaying the photos in response to the determined ranking.

  • Patent number: 7706537
    Abstract: A system and method for performing SRNS relocation in a communications system transmits radio resource information including a ciphering parameter from a source RNC to a target RNC, modifies the ciphering parameter to coincide with a deciphering parameter which a user terminal uses when out-of-sequence data is received, ciphers a data unit based on the modified ciphering parameter, and transmits the ciphered data unit from the target RNC to the user terminal. The method may be modified to operate in UM mode or AM mode and to transmit data over one of several radio bearers. In accordance with another embodiment, the system and method transmits radio resource information from a source RNC to a target RNC and then transmits a data unit from the target RNC to a user terminal. In this case, the data unit including a transmission sequence number which consecutively follows a transmission sequence number of a data unit last transmitted from the source RNC to the user terminal.
