- the mobile terminal (MN) power in mopile IP also extends from home agent (HA) to MN to MAP (mobility anchor point) in layered mopile IP (HMIP), and in 3GPP (3rd Generation Partnership Project).
- Tunnel technology is used from MN to GGSN (Gateway GPRS Support Node).
- path coupled signaling such as RS VP (Resource reSerVation Protocol) and NSIS (Next Step In Signaling) (see Non-Patent Documents 1 and 2 below)
- QoS Quality of Service
- aggregation for this signaling is performed in the tunnel. That is, an end-to-end signaling message is sent outside the tunnel, and an aggregation signaling message is sent inside the tunnel. And mapping of these signaling is done at the entrance and exit of the tunnel.
- NSIS NSIS WG
- the proxy on the subnet to which the terminal moves before moving Send a message containing the session identifier currently in use.
- the proxy sends a message containing this session identifier on the route that is going to establish a new QoS route, so that the QNE where the current route and the new route begin to overlap, that is, the CRN (CRoss ove node)
- the CRN CRoss ove node
- a plurality of MN (Signal Node (SN: Signal Node) 1 ⁇ to Signal Node (SN: Signal Node) 105 ') forces each communication partner node (End Node (EN: End node) 14r to End Node (EN: End node) 145 ') are communicating through domain 120' and are aggregated inside domain 12CT.
- a supplementary service here, QoS guarantee service
- the procedure for releasing the QoS path for the tunnel that was set up between the aggregator 11 ⁇ and the first one is as follows. If the procedure is used, for example: Note that m, k, and n shown in FIG. 10 are arbitrary natural numbers, and the number of each component is not limited to the number shown in FIG. The same applies to Fig. 1 described later.
- the MN sends a message for establishing a QoS path to each communication partner node at the destination via a new aggregator 115 'and a deaggregator 11'. Then, each CRN (CRN13 to 135 is found. Each CRN releases an old QoS path, so there is an aggregator 11 / and a message for release in the other direction (referred to as a tear message). Every time the tear message reaches Deaggregator 1 W, the information of this message (End'end's QoS route) is compared with the information of the QoS route for the tunnel.

At that time, the CRN discovery unit 904 includes the information necessary for discovering the Pre CRN received from the processing request message and the IP address of the deaggregator 713 in the detection message. In addition, if a session is aggregated in a discovery message, you may want to explicitly include that information.
- Each proxy in the aggregation management method according to the third embodiment of the present invention The processing in the unit is an example, and other processing may be performed by another unit.
- the block diagram of the components of the dual gate node according to the third embodiment of the present invention is the block diagram of the dual gate node according to the first embodiment shown in FIG. Since this is the same, a delegation node according to the third exemplary embodiment of the present invention will be described with reference to FIG.
- the deggregator is configured by a delegation control unit 401, a signaling management unit 402 (corresponding to the above-described reception unit and release processing unit), and a storage unit 403.
- the delegation control unit 401 manages the delegation process for data traffic.
- the signaling manager 402 processes the received sendering message. For example, based on the release request message received from the aggregator, the signaling manager 402 releases the QoS path for the old tunnel, and at the same time, the signaling manager 402 also has its own (deaggregator 713) power for each CRN (CRN73 1 to 735). The QoS route up to is also released.
- the storage unit 403 stores, for example, information related to the current end 'to' end signaling message and the aggregated session, and includes information on the ID of the old QoS path for the tunnel. It is.
- the storage unit 403 may store information that needs to be stored through a series of processes. Note that the processing in each unit of the deggregator according to the third embodiment of the present invention is merely an example, and other units may perform processing that may be performed by other units.
- each functional block used in the description of the above embodiment is typically realized as an LSI which is an integrated circuit. These May be individually made into one chip, or may be made into one chip so as to include a part or all of them.
- IC system LSI
- super LSI super LSI
- ultra LSI depending on the difference in power integration of LSI.
- the method of circuit integration is not limited to LSI, and may be realized by a dedicated circuit or a general-purpose processor.
- An FPGA Field Programmable Gate Array
- a reconfigurable processor that can reconfigure the connection and settings of the circuit cells inside the LSI may be used.
- integrated circuit technology that replaces LSI emerges as a result of advances in semiconductor technology or other technologies derived from it, it is natural that the integration of functional blocks may be performed using this technology. For example, biotechnology can be applied.
- the aggregation management method, aggregate node, and dual gate node according to the present invention can manage aggregation quickly and efficiently, aggregation of a communication network including an aggregated session can be performed. This is useful for aggregation management methods, aggregate nodes, and dual gate nodes that perform management.
