A home base station via which a plurality of mobile communication devices are connectable in a communication network, the home base station having an associated closed subscriber group (CSG) and including a unit for receiving a connection request from a mobile communication device wherein the connection request includes an indication of whether the mobile communication device is a member of the CSG associated with the home base station, a unit for monitoring congestion levels for the home base station and for indicating when the home base station is in a congested situation, a unit for determining if the mobile communication device requesting connection is the member of the CSG associated with the home base station from the indication of whether the mobile communication device is the member of the CSG associated with the home base station, and a unit for controlling access to the home base station.

Communication system

A communication system is described in which mobile telephones are able to roam between neighbouring home node base stations. Techniques are described for allocating U-RNTIs to mobile telephones by the home base stations or the home base station gateway. Techniques are also disclosed for target home base stations to be able to retrieve information needed to respond to a Cell Update request received from a mobile telephone.

In order to implement handover to a femto cell without making any modification to UEs, a gateway () relays traffic between a core network () and a plurality of base stations (_-_) that are respectively incorporated into the core network () through a public network. The gateway () generates an RRC Connection Release message for prompting establishment of a new RRC connection, when it is notified from the core network () that a mobile station () is handed over to any one of the plurality of base stations (_-_). Then, the gateway () causes the core network () to instruct a control device (), which has established an RRC connection to the mobile station (), to transfer the RRC Connection Release message to the mobile station ().

Gateway and control device, and communication controlling methods for the same

A gateway is connected to a plurality of base stations and a core network. The gateway includes a receiver that receives, from the core network, a message establishing a communication path to any one of the plurality of base stations, wherein the message includes a received Access Point Name (APN). The gateway also includes a controller that determines, in response to the APN included in the massage, a destination of the message using information indicating a destination base station corresponding to the received APN.

Gateway, communication system, method of controlling gateway, and computer readable medium therefor

A communication system is described in which a home base station operating in a hybrid access mode is able to provide preferential connectivity to mobile communication devices that are members of a closed subscriber group associated with the home base station compared to mobile communication devices that are not members of the closed subscriber group.

A wireless communication system includes a wireless base station FAPwhich communicates with a mobile communication terminal UE; a core network apparatus CNwhich is a higher-level apparatus of the wireless base station; and a femto wireless base station gateway GWwhich relays between the FAPand the core network apparatus CN. The wireless base station FAPincludes a determination unitwhich determines whether to stop voice call reception processing or voice call transmission processing with reference to determination information upon detection of a voice call reception to the mobile communication terminal UEwithin a communication service area or a voice call transmission from the mobile communication terminal UEwithin the communication service area in the FAP; and a signal processing unitwhich informs a higher-level apparatus of a message including a determination result when the determination unit determines to stop the processing.

Wireless base station, wireless communication system, wireless communication method, and computer-readable medium storing device

A panel carrying device, including a panel holding deviceholding a panel; a second link mechanism connected to the panel holding device; a first link mechanism pivotally fitted to the second link mechanism; a slide mechanismwhich moves the first link mechanism in a panel carrying direction; and a swing mechanismwhich swings the second link mechanism.
