  • Publication number: 20140247132
    Abstract: The present technique relates to an information processing device and an information processing method that can realize new forms of communication tools. LEDs emit light in accordance with a light emission pattern specified by a combination of light emission parameters that represent light emission characteristics. A light emission control unit performs control to select a light emission pattern from among two or more preset light emission patterns, based on a change in physical quantity resulting from an action of a user, and cause a light-emitting unit to emit light in accordance with the selected light emission pattern. The present technique can be applied to information processing devices used as communication tools.

  • Publication number: 20130281081
    Abstract: In order to improve the accuracy of at least one of detecting that a UE camps on a femto cell and detecting that the UE decamps from the range femto cell, a gateway (110—1) forms a gateway system and relays traffic between a core network (20) and a base station (30—2). When TMSI or P-TMSI temporarily assigned to a UE (40—1) requesting to camp on the base station (30—2) is received from the base station (30—2) through a public network, the gateway (110—1) requests a server (120), which communicates with the core network (20) and the gateway (110—1), to notify IMSI permanently assigned to the UE (40—1) and associated with the TMSI or P-TMSI. In response to the request, the sever (120) acquires the IMSI from the core network (20) and notifies it to the gateway (110—1). The gateway (110—1) identifies the UE (40—1) by using the IMSI.

  • Patent number: 7912474
    Abstract: When a cell load becomes higher than a call setup threshold value for a first channel (CS channel), a second channel (PS channel) is changed into a channel having a low transmission rate. Consequently, the cell load is reduced and no cell loss occurs in the first channel. Therefore, the call loss rate of a first communication service is lowered. Simultaneously, a handover threshold value is higher than the call setup threshold value for the first channel so that a failure rate of handover is lowered.

  • Patent number: 7637654
    Abstract: In order to measure specific heat, the measurement time is very long and the instrument is very expensive. The specific heat may be calculated based on the thermal time constant obtained from the change of the sample temperature when the predetermined amount of sample with known density at the first temperature is introduced in the environment at the second temperature. This measuring method can use the oscillatory densitometer. The predetermined amount corresponds to the volume of the sample to be introduced in the oscillatory densitometer, the density is a measurement result of the oscillatory densitometer, and the thermal time constant corresponds to the time constant of the oscillation period of the oscillatory densitometer.

  • Patent number: 7554940
    Abstract: In a mobile communication system, when a connection necessary to provide a service supporting high-speed data communication referred to as an MBMS (Multimedia Broadcast Multicast Service) is configured on an Iu interface, contention with the other packet communication service is eliminated. As a logical connection established between an SGSN (Serving GPRS (General Packet Radio Service) Support Node) and a Radio Network Controller in a Core Network 10, a PS (Packet Switching processing) functional connection for an existing packet communication service and a connection for a new MBMS service offering high-speed data communication are provided separately and independently from each other. This eliminates the contention between different types of services of the PS service and the MBMS service to thereby enable executing processings of such different types of services without being conscious of mutual processings.

  • Patent number: 7146629
    Abstract: Out of viewers of the same content, multi-user talking service is provided to only viewers who wish to enjoy the content in a large number of people. Only when an address of a terminal 4, 5 that has transmitted a request for participation in multi-user talking is registered in a viewer management DB (which manages viewers of contents), a content distribution/multi-user talking service center 1 registers the above-mentioned address into a participant management DB (which manages participants in multi-user talking) associating the address with identification information of a content that is registered in association with the address in question in the viewer management DB. Then, for each content, respective pieces of talking data received from addresses registered in association with identification information of said content in the participant management DB are synthesized to generate multi-user talking data, and generated multi-user talking data is transmitted to each of said addresses.
