摘要： Disclosed is a technique for enabling a device that needs to send high priority and high bandwidth user plane traffic to send the user plane traffic even in the case where a group bandwidth has an upper limit in group-based communication. According to the technique, when an MTC device that is to send high priority and high bandwidth user plane traffic sends a service request to a network node (P-GW 213a), the network node allows use of a minimum bandwidth bearer in the case where the upper limit of the group bandwidth is exceeded. The MTC device sends a traffic sending request to an MTC server 214a via the bearer. The MTC server stops traffic of an appropriate other MTC device, to secure a bandwidth for the MTC device having the high priority and high bandwidth user plane traffic.

摘要： Disclosed is a technique to eliminate wasted tunneling encapsulation processing during redirection of a packet. According to the technique, when a packet of a first connection passing through a LMA 111 and a MAG 121 using a first address of an interface 131 of a MN 130 is redirected to a second connection passing through a LMA 112 and a MAG 122 using a second address of an interface 132 of the MN 130, a redirection tunnel T1 is established between the LMA 111 and the LMA 112. When the MAG 122 knows the first address, the LMA 112 encapsulates a packet addressed to the first address that is redirected via the tunnel T to be addressed to the MAG 122 for transferring.

摘要： Disclosed is a technique in which, when respective addresses of multiple interfaces of a mobile node are registered with a mobile management device, a delay in transmission of packets destined to addresses other than the source address of a bulk registration message is prevented. According to the technique, an MN 100 uses each of addresses associated with IFs 1000 and 1001 as a source address, respectively, to send a HA 101 an individual registration BU message S30, S31 for registering the source address individually. When receiving the individual registration BU message S30, S31, the HA 101 registers the source address as having been verified through ingress filtering of a foreign network domain 11, and sends a BA message S32, S33 to authorize bulk registration for updating the respective addresses in bulk.

摘要： A technology is disclosed for preventing packet and transferring packets to a switched interface with minimal delay, when a mobile node switches a using interface. According to the technology, when a MN 200 is communicating with a MAG (WLAN) 232, a PBU message 301 has already been transmitted from the MAG (WLAN) 232 to the LMA 220, and binding related to a WLAN connection 242 is already registered in the LMA 220. When an interface switching event 300 is generated, the MN 200 transmits to the MAG (WLAN) 232 via the WLAN connection 242, a binding in-advance registration message 302 for registering a binding in advance. When the MAG (WLAN) 232 detects disconnection 310 of the WLAN connection 242, the MAG (WLAN) 232 transmits a registration delete/trigger message 312a to the LMA 220, registers and triggers in the LMA 220 the in-advance registration binding registered in the MAG (WLAN) 232, and deletes the PBU message 301.

摘要： Disclosed is a technique for switching a forwarding address of a packet destined for a mobile node in a local mobility domain when the mobile node has a plurality of interfaces so that the packet will be forwarded to the mobile node. According to the technique, an MN 101 receives network information 40 including a domain ID 402 from a network through two or more IFs 1010 and 1011. Based on the domain ID 402 in the network information received, when determining that the IFs 1010 and 1011 are attached to the same domain, the MN 101 decides to allocate the same address to the IFs 1010 and 1011, and requests MAGs 111 and 112 connected to the IFs 1010 and 1011, respectively, to bind the same address to each of link identifiers of the IFs 1010 and 1011. Based on the request, the MAGs 111 and 112 perform binding to forward, to the MN 101, packets destined to the same address of the MN 101.

摘要： Disclosed is a technique to eliminate wasted tunneling encapsulation processing during redirection of a packet. According to the technique, when a packet of a first connection passing through a local mobility anchor (“LMA”) 111 and a mobile access gateway (“MAG”) 121 using a first prefix of an interface 131 of a mobile node (“MN”) 130 is redirected to a second connection passing through a LMA 112 and a MAG 122 using a second prefix of an interface 132 of the MN 130, a redirection tunnel T1 is established between the LMA 111 and the LMA 112. When the MAG 122 knows the first prefix, the LMA 112 encapsulates a packet addressed to the first prefix that is redirected via the tunnel T to be addressed to the MAG 122 for transferring.
