A secondary base station (2) receives an SeNB addition request message (302) from a second master base station (3) while providing a radio terminal (4) with a secondary cell group (SCG) for DC in cooperation with a first master base station (1). If the SeNB addition request message (302) explicitly or implicitly indicates that a master base station in DC for the radio terminal (4) is to be changed from the first master base station (1) to the second master base station (3), the secondary base station (2) considers that the SeNB addition request message (302) requests modification of the SCG that has already been configured. It is thus, for example, possible to contribute to performing a procedure for changing a master base station in Dual Connectivity (DC) by using existing inter-base station interface procedures and inter-base station signaling messages. |

Then, in a case where there is no duplication of the chunk, the data optimization unit stores the chunk, and stores the hash value, the data size of the chunk, and the position of the chunk in a hash information storage unit. Then, the data optimization unit compresses the chunk, and transmits compressed data to a transport optimization unit. |

System providing faster and more efficient data communication
A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine. The IP address of the server in the communication request is transmitted to the acceleration server, which provides a list of agents to use for this IP address. The communication request is sent to the agents. One or more of the agents respond with a list of peers that have previously seen some or all of the content which is the response to this request (after checking whether this data is still valid). The client then downloads the data from these peers in parts and in parallel, thereby speeding up the Web transfer, releasing congestion from the Web by fetching the information from multiple sources, and relieving traffic from Web servers by offloading the data transfers from them to nearby peers. |

System and method for real-time load balancing of network packets
Internet protocol packets are statelessly identified as associated with a particular session-instance by identifying a key, or session-instance identifier, within the data (or payload) portion of a user plane packet.

Using this stateless identification, transmitted user plane packets are automatically routed at the transmission speed of the transmission link using a method that automatically balances the analysis processing load between network probes. The load is balanced by routing the user plane packet to a network probe that is either already analyzing the session-instance or by routing the user plane packet to a system that has processing capacity to analyze a new session-instance. The network probe then analyzes the user plane packet and the session-instance to measure the quality of the user experience of the session-instance and performance of the network. |

Electric circuit device
An internal electric circuit device that is connected to a connector terminal at the time of being short-circuited can be protected, but a load connected to the connector terminal has not been able to be protected. When a voltage of a cathode of a diode becomes a voltage equal to or more that an output voltage of a power source circuit by a short circuit of a positive terminal, an output voltage of an amplifier changes from the output voltage of the power source circuit to a voltage of a point connected to a negative power terminal of the OP amplifier. When the output voltage of the amplifier becomes 0 V, a voltage difference between the gate and the source of a switching element becomes equal to or more than a predetermined voltage. Therefore, the drain and the source of the switching element enter an open state, and the current flowing a negative terminal is blocked. Therefore, it is possible to protect a load from overcurrent. |
