摘要： A mobile node (MN) transmits a (4) echo request to the effect that the source address is set to be a new care of address (nCoA) right after transmitting a (3) binding update (BU) for a home agent (HA). The nAR having received the (4) echo request intends to transmit an echo reply to the nCoA being the source address of the echo request. However, at this time, since an entry regarding the nCoA does not exist in a neighbor cache of the nAR, the nAR transmits (5) neighbor solicitation (NS) to the MN, and generates a neighbor cache entry of the nCoA. After this, at the time when a binding acknowledgment (BA) has arrived at the nAR, since the entry of the nCoA exists, the (8) BA and data packets (9) to (11) arriving at the nAR following the (8) BA are transferred to the MN without buffering in the nAR, corresponding to the entry of the nCoA generated at the time of transmission of the (7) echo reply.

摘要： When a mobile node MN moves from an access router AR3 to another access router AR4, it sends a multi-binding on request to a mobility agent MA1 and then moves ({circle around (1)}). Receiving the multi-binding on request, the mobility agent MA1 voluntarily configures prospective CoA's (probable CoA's) The probable CoA's are added as forwarding addresses while an M bit is set on in an register of the mobile node MN on a binding cache ({circle around (2)}). When the mobility agent MA1 receives a capsuled packet addressed to the mobile node MN thereafter, it tunnel-forwards the packet to CoA3, probable CoA2, and probable CoA4 according to the binding cache ({circle around (3)}).

摘要： An object of the present invention is to decrease a care-of address update duration in switching of a link used for connection to an IP network by a mobile node (MN). MN acquires a list of access routers (ARs) existing on neighboring links to the link used for connection by the mobile node and creates a list of care-of addresses (CoAs) corresponding to the respective ARs entered in the list, each CoA being used as a destination of MN at a link on which an AR corresponding thereto exists. After the change of the connected link, MN acquires a data link layer address of AR existing on the link after the change and detects a default router on the basis of the address with reference to the access node list. Furthermore, MN detects a CoA with a network prefix corresponding with a subnet prefix of the default router, as a primary CoA and requests MAP to register a binding between the primary CoA and HoA.

摘要： An apparatus is adapted to configure a virtual communication device that includes communication devices accessible to the apparatus. A signal interface receives from a calling communication device information data including first and second content parts, and an information separating unit separates the first and second content parts of the information data. A DMF unit identifies communication attributes of the communication devices accessible thereto and identifies the communication devices capable of processing information corresponding to at least one of the first and second content parts. A virtual terminal interface sends information corresponding to the first content part to a first communication device identified as being capable of processing the first content part and information corresponding to the second content part to a second communication device capable of processing the information of the second content part, to thereby form the virtual communication device by at least the first and second communication devices.

摘要： In a wireless base station, when a newly provided control unit receives an IP packet from one mobile station (102), it refers to a destination address in control information added to the IP packet (104), and determines whether the IP packet is one to be broadcast or multicast (106). If the value of destination address is at a value indicative of broadcasting or the like defined by IP, the IP packet is copied according to the subnet, and is sent back to a wireless link layer processor with its contents intact (108). Further, the wireless link layer processor is commanded to broadcast the sent-back IP packet in a wireless area and so forth (110), whereby the IP packet can be broadcast into a cell and so forth.

摘要： Provided is a mobile communication system capable of reducing interference in uplinks and downlinks to achieve excellent communication quality. A mobile station receives cell selection reference signals from a first base station and a second base station to connect before and after a handover, and measures received power values of the cell selection reference signals. The mobile station acquires uplink transmitted power values from the mobile station to the first base station and to the second base station. The first base station and the second base station control a power of the cell selection reference signal so that the uplink transmitted power values from the mobile station to the first base station and to the second base station become substantially equal and so that a received power value at the mobile station of the cell selection reference signal becomes substantially equal to a predetermined reference power value.
