Problems solved by technology

Therefore, for example, in the case where the MN 10 switches between the subnets 20 and 30 and changes the CoA of the MN 10, although it is necessary to perform address change-related processing in the QoS path in addition to the flow change, RSVP cannot handle Such a change, which results in broken QoS guarantees (first problem: difficulties encountered in changing QoS paths)
Moreover, even in the case of newly setting up a QoS path, if an overlapping portion occurs between QoS paths before and after switching, it is possible to cause double resource reservation (double reservation) in this overlapping portion (second problem: double resource reservation )
Difficulties are encountered in returning it to the MN 10 as a free resource (for a new path after the MN 10's move), which thus makes it difficult for the MN 10 to obtain accurate vacancy information about said resource

Embodiment Construction

[0140] Embodiments of the present invention will be described below with reference to FIGS. 1-8 , 15 and 16 . FIG. 1 is an explanatory view showing the configuration of a communication system according to an embodiment of the present invention. In FIG. 1 , the QoS path (path 24 ) established for the CN 60 in the state where the MN 10 was connected to the subnet 20 before handover is shown by a solid line. On this route 24, AR 21, NE 62, QNE 63, NE 64, QNE 65, and QNE 66 exist in the direction from MN 10 to CN 60. Similarly, in the case where the MN 10 establishes a connection with the subnet 30 after handover, the QoS path (path 34 ) established for the CN 60 is shown in dotted lines. On the route 34, there are AR 31, QNE (Proxy) 68, QNE 67, NE 64, QNE 65, and QNE 66 in the direction from MN 10 to CN 60. Therefore, the QNE (CRN) at which the old path (path 24 ) and the new path (path 34 ) intersect each other is QNE 65 .

[0141] Next, the functions of the MN 10 will be exp...

Abstract

There is disclosed a technique for allowing a mobile terminal that has been handed over to quickly and continuously receive an additional service (e.g., QoS assurance) that had been received before the handover. According to the technique, when being handed over, a mobile terminal (MN) (10) selects, as a proxy, a node (QNE) (proxy) (68) that is located near a network AR (access router) (31) belonging to a subnet (30), into which the MN is moving, and that has an NSLP for the QoS. The MN then transmits, to the proxy, a message including a flow identifier and a session identifier that are related to a path (24) established with a CN (60) before the handover. The proxy transmits, to the CN, a message including these flow and session identifiers, then establishes, based on the result of a response to this message, a new path (34), and then finds a crossover node at which the two paths are joining.

Description

technical field [0001] The present invention relates to a communication handover method related to handover of a mobile terminal (mobile node) performing wireless communication, a communication message processing method, and a program for executing these methods by using a computer, and more particularly to a communication handover related to a mobile node described below A method, a communication message processing method, and a program for executing these methods by using a computer, the mobile node is designed to perform wireless communication by using the Mobile IPv6 (Mobile Internet Protocol Version 6) protocol, which is a next-generation Internet protocol. Background technique [0002] As a technology capable of providing a connection to a communication network such as the Internet in a seamless manner to a user who obtains access from a mobile terminal through a wireless network to a communication network such as the Internet even in the middle of a movement, the use o...
