摘要： Disclosed is a technique to enable a communication node to acquire predetermined newer information (e.g., configuration information) held by another communication node while minimizing power consumption by communication nodes. According to the technique, when receiving a request for configuration information from a new MTC device 100, a MME 220 checks whether an existing MTC device 110 as a request target for configuration information connects or not. When the existing MTC device does not connect, the new MTC device is notified of time information (e.g., next connection time of the existing MTC device, a next connection time of a new MTC device or a next connection time zone of the new MTC device). This time information enables the new MTC device to specify a time after the MME acquires and holds the configuration information from the existing MTC device. The new MTC device reconnects based on this time information, whereby the new MTC device can acquire desired configuration information from the MME.

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： When a mobile terminal transmitting/receiving a packet using a plurality of IP address types performs a handover to an access network (single address type connection network) permitting transmission/reception of a packet using a single IP address only, an IP address not permitted is unfortunately discarded at an access network as a handover destination. Disclosed is a technique configured so that a mobile terminal (UE 1) detecting a handover to the single address type connection network establishes a temporary connection with a mobility management gateway (PGW 5) and thereafter acquires an address of an ePDG 8 located at a core network and informs the ePDG of a communication state before the handover via a PDN using the temporary connection. The ePDG informs the PGW of the communication state of the UE before the handover. Thereby, the communication state of the UE before the handover is achieved with the PGW via the ePDG and the PDN.

摘要： Disclosed is a technique to allow a network operator of a mobile node to securely reject an unfavorable address for use in route optimization. According to the technique, when receiving a HoTI message 40 (Step S1), a HA 30 checks whether a sender address CoA of an external IP header 41 is a registered CoA or not (Step S2), and when it is not a registered CoA, the HA 30 discards the HoTI message 40 (Step S3). When it is a registered CoA, the HA 30 checks whether CoA1 in a CoA option 46 is OK for route optimization or not (Step S4). When it is OK for route optimization, the HA 30 transfers a decapsulated HoTI message 42 to a CN 20 (Step S5). On the other hand, when it is not OK for route optimization, the HA 30 discards the HoTI message 40 (Step S3).

摘要： A technique is disclosed for preventing a mobile terminal from unnecessarily connecting to a local connection service provided by a mobile router. In a communication system, a UE 10 sends user preference information to a forwarding node 20 before the UE connects to the forwarding node, which is installed in a moving body 110 as an access point of the UE to forward information to the UE. The forwarding node determines whether information capable of being supplied to the UE is appropriate for a user of the UE based on the preference information and sends the determination result to the UE. When the UE becomes connectable to the forwarding node, the UE does not connect to the forwarding node if the information capable of being supplied is not appropriate for the user of the UE based on the determination result; else the UE connects to the forwarding node.
