  • Patent number: 10299170
    Abstract: A source Home Node B (HNB) of a mobile communication system transmits, to a Home Node B-Gateway (HNB-GW) of the mobile communication system, a Direct Transfer message including a Target Radio Network Controller (RNC)-ID and a Target Cell ID. A mobile station receives a channel reconfiguration message from the source HNB, synchronizes with the target HNB, and transmits a channel reconfiguration complete message to the target HNB. The HNB-GW constructs a RANAP relocation request message using the Target RNC-ID. The HNB-GW transmits the RANAP relocation request message to the target HNB, and detects a relocation from the source HNB to the target HNB, after receiving the Direct Transfer message from the source HNB.

  • Patent number: 9992851
    Abstract: The present technique relates to an information processing apparatus and a method capable of realizing a communication tool of a new mode. An LED emits light according to a light emission pattern identified based on a set of light emission parameters indicating characteristics of light emission. An action control unit controls the light emission pattern of the LED based on a relationship between the self apparatus and a group to which the self apparatus and at least one other information processing apparatus including the LED belong, or a relationship between the other information processing apparatus and the self apparatus belonging to the group. The present technique may be applied to an information processing apparatus used as a communication tool.
