Abstract

Disclosed is a technique for reducing delay when a mobile communication terminal starts communication and reducing consumption of a power resource of the mobile communication terminal. An MN (mobile node) (1012) has plural interfaces (IF-1 (1030) and IF-2 (1028)). One interface IF-1 is connected to a connection point (serving PoA (1008)). When switching over from communication using the IF-1 to communication using the IF-2, the MN transmits a paging request message via the IF-1 and the serving PoA to a connection point (target PoA (1010)) attempted to connect using the IF-2. The target PoA that has received the paging request message reduces a beacon transmission cycle and sets transmission slots for the MN so that the connection of the MN can be established efficiently.

Dependent claims

A mobile communication terminal comprising:

an interface for connecting to a network through radio communication;
identification information acquiring means for acquiring identification information of a second connection point on the network, to which the mobile communication terminal attempts to connect later;
and
request message transmitting means for transmitting a request message requesting preparation for connection to the second connection point from the interface being connecting to a first connection point on the network to the second connection point via the first connection point.

1 more element

A communication device located on a network, comprising:

request message receiving means for receiving a request message requesting preparation for connection to a second connection point, to which a mobile communication terminal attempts to connect later, via a first connection point being connecting through radio communication to an interface of the mobile communication terminal to enable the mobile communication terminal to connect to the network;
and
response message transmitting means for instructing the second connection point to prepare for connection of the mobile communication terminal when the request message receiving means receives the request message, and transmitting a response message, as a response to the request message and indicating that the preparation is made, to the mobile communication terminal via the first connection point.
