摘要： Disclosed in a technique for performing data transmission between units efficiently in an imaging device, in which a camera unit and the other units (particularly a display unit) are separated and connected wirelessly, to improve convenience. According to this technique, video content data imaged by an imaging section is encoded, by means of hierarchical coding, into checking content coded data of a core layer and saving content coded data of an enhancement layer. The checking content coded data is sent immediately from a checking content transmission section 906 to a display unit 950 through wireless communication, and a display thereof is output. On the other hand, the saving content coded data is stored in a recording section 907 together with the checking content coded data. Thus, both a rapid display of video content data and storage thereof while keeping the quality are achieved.

摘要： Disclosed is a technique to enable a user equipment at a remote place to perform local IP access to a locally-accessible network with simpler procedure and such a configuration while achieving the efficiency of costs and facility. According to the technique, a network (LIA-PDN 161) capable of dealing with a local IP access by a user equipment (UE 101) is placed on a core network 141. When the UE establishes a PDN connection with the LIA-PDN, the UE simultaneously transmits information concerning the LIA domain network 111 as well, to which the UE wants a local IP access. On the basis of this information, the LIA-PDN establishes a PDN connection with the LIA domain network, and the LIA-PDN transfers a packet, whereby the UE can access the LIA domain network via these PDN connections.

摘要： A technique is disclosed to decrease unnecessary routing during communication between a mobile node and a correspondent node in case a home agent of the mobile node is a mobile home agent. According to this technique, HA 112 positioned in a home network 102 and HA 114 of MN 130 are included. In a communication system, where HA 114 is a mobile home agent, and a mobile network 104 of HA 114 is hierarchized under the home network 102, HA 114, which is a home agent, discovers HA 112 positioned in the home network 102 when it is detected that it is away from the home network 102 and delegates binding cache entry of MN 130 under its own management to HA 112 so that HA 112 acts as a home agent for MN 130.

摘要： A new technique is disclosed, by which a mobile terminal after executing handover between subnets can quickly perform packet transmission to outside immediately after the handover. According to this technique, after deciding the execution of handover, MN (mobile terminal) 10 requests an external transmission address (link local address of an access router belonging to a subnet or of a default router after the handover) relating to a subnet connected after the handover at the same time as the transmitting of RtSolPr message to PAR21 connected before the handover. PAR acquires the external transmission address in response to the request and transmits the external transmission address to MN together with a response by PrRtAdv message to MN. MN sets up the external transmission address as acquired before the handover to the packet to be transmitted after the handover.

摘要： A mobility condition determination unit, provided in an MIP controller that manages moving of a communication node, obtains and examines various conditions that have occurred as the communication node is moving, selects an appropriate HoA (e.g., the home address of an MN1) for the current connection situation, and transmits, to a multihoming controller, a notification indicating that a set of the selected HoA and a CoA constitutes appropriate addresses to be used. Upon receiving the notification from the mobility condition determination unit, the multihoming controller transmits, to the MIP controller, an address (Addr2) consonant with the received HoA, and the MIP controller performs packet communication using the HoA or the CoA consonant with the address.

摘要： Disclosed is technique for avoiding packet reflection between home agents. According to the technique, a MN 10 includes a home address (HoA1) assigned thereto from a home network 12, and a home address (HoA2) assigned thereto from a home network 14. CoA is further acquired from a foreign network 15. Then, the MN uses the home addresses as care-of addresses, and performs binding-update including HoA1-HoA2 for the HA 12 and binding-update including HoA2-HoA1 as well as HoA2-CoA for the HA 14. A packet transmitted from a CN 16 to HoA1 is encapsulated by the HA 12 and transferred to the HA 14. The HA 14 refers to a source address of the received encapsulated packet and selects CoA as a transfer destination address instead of HoA2 having the same prefix.
