Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for fast cell search in a communication system for reducing the overhead of the communication system caused by a number of cell identifiers. SOLUTION: Reference sequences are constructed from distinct "classes" of GCL sequences that have an optimal cyclic cross correlation property. The fast cell search method disclosed detects the "class indices" with simple processing. In a system deployment that uniquely maps sequences of certain class indices along with a circular shift amount in time domain to certain cells/cell IDs, the identification of a sequence index, and its circular shift will therefore provide an identification of the cell ID.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved transmission method and a device for transmitting quickly and efficiently an information from two or more transmission source devices to a sending end device. SOLUTION: Two or more transmission source devices (110, 120, 130) can transmit an information to a sending end device (100) from the transmission source device. The information transmitted to the sending end device (100) from the transmission source device takes usually a form of an electronic product code ("EPC") of binary digit or an identity ("ID") information. The method utilizes a data scramble and a scramble analysis, a channel selection and a transmission, an effectiveness and an ineffectiveness setting of a group transmission, a correlation determination, and the technique of collision relaxation.

Abstract:
PROBLEM TO BE SOLVED: To provide a resource assignment system which produces a better trade off between a performance of a cell outer and an overall spectrum efficiency. SOLUTION: A power control parameter fraction is determined, based on the maximum transmission power, a propagation loss threshold and a channel condition. A data rate which can be supported is determined, based on a transmitting power level, and a minimum bandwidth is determined, based on the data rate which can be supported.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for setting up a session initiation protocol exchange between a wireless communication device and a network. SOLUTION: The method includes the steps of: requesting a channel; receiving an allotment; transmitting a request for connection management service; receiving an authentication request; receiving a ciphering mode command; transmitting a ciphering mode completion; determining whether an associated control channel is set up; transmitting a packet resource request in a dedicated control channel to make it possible to transmit, through the dedicated control channel, a message related to setting of the session initiation protocol exchange as a result of determination that the associated control channel is not set up; transmitting a packet control acknowledgement; and transmitting an SIP message through the associated control channel.

Abstract:
PROBLEM TO BE SOLVED: To disclose a method and system for sharing broadcast service information in a communication network (106). SOLUTION: The communication network includes a plurality of electronic devices. The method includes retrieving metadata (304) corresponding to a broadcast service. The metadata contains broadcast service information pertaining to the broadcast service. The method also includes formatting the metadata (306). Moreover, the method includes sharing (308) the service description file with at least one of the plurality of electronic devices. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a security mode method in which a mobile station is capable of reducing the number of dropped calls even if non-integrity-protected layer 3 messages and integrity protection initiation messages are processed out-of-order. SOLUTION: The security mode method receives (210) a layer 3 message in a first domain from a network, determines (220) if the layer 3 message has integrity protection information, ascertains (240) if a security mode has been initiated in the first domain, and forwards (260) the layer 3 message to an upper layer, if the layer 3 message lacks integrity protection information and a security mode has not been initiated in the first domain even if security mode has been initiated in a second domain. This method allows the mobile station to process a non-integrity-protected layer 3 message from one domain even if integrity protection has been initiated in another domain.

Abstract:
PROBLEM TO BE SOLVED: To save power by utilizing a non-CDMA communication path and to send emergency communication onto a CDMA communication path. SOLUTION: A portable communication device 100 also includes a controller 112 coupled to first transceiver circuitry 104 and second transceiver circuitry 116 for providing a deregistration message to the second transceiver circuitry 116 for transmission therefrom in response to determining that the portable communication device 100 is within signal coverage of the first communication path, activating the first transceiver circuitry 104 to send and receive signals on the first communication path, deactivating the second transceiver circuitry 116, and thereafter activating the second transceiver circuitry 116 at times separated by a predetermined time interval to monitor one or more housekeeping channels of the second communication path.

Abstract:
PROBLEM TO BE SOLVED: To provide a metal can battery assembly for inhibiting short-circuiting generated by shock related to deformation in a metal can. SOLUTION: A tapered assembly 900 has a taper at least at one of both end sections. A center height 907 is higher than an outer-periphery height 908. A first edge 906 having each taper in each of sectional and outer shapes is provided. The tapered section allows a cavity to be present between the corner section of the metal can and an electrode assembly. The "shock absorption region" inhibits damage to the internal electrode assembly by external shock to the can and improves reliability in the cell. COPYRIGHT: (C)2006,JPO&NCIPI
