Embodiment 1

[0082] FIG. 1 is an arrangement diagram of a mobile communication system and external networks in this embodiment.

[0083] In FIG. 1, a mobile communication device 101 is a terminal unit that processes information. A mobile router 102 with a public wireless interface allows communication with the mobile communication device 101 . At the same time, the mobile router 102 has a plurality of interfaces connected to the connection unit 103, which is provided in the external network 104, and has the ability to relay information from the mobile communication device 101 to the external network 104 or from the external network 104 to the mobile communication device. 101 features. The mobile communication unit 101 and the mobile router 102 form a mobile communication system.

[0084] For example, the connecting unit 103 may be an access point of IEEE802.11, an access point of HIPERLAN, an access point (base station) of a PDC network, an access point (base station) of a third-generati...

Embodiment 2

[0121] In Embodiment 2, mobile communication device 101, mobile router 102, and mobile communication system 105 have the same configuration as Embodiment 1 shown in FIG. 1 .

[0122] FIG. 11 is a block diagram showing the configuration of the mobile communication device 101 of the present invention.

[0123] In FIG. 11 , the candidate interface selection section 111 performs processing to select a candidate interface, and the mobile router 102 selects a candidate interface from the information stored in the service type record section 205 and the interface record section 206 when the current mobile communication device 101 communicates with the external network 104. choose. The candidate interface selection section 111 has the function of an interface decision section plus a priority order decision section for deciding the priority order in the external interface group as a set of the external interfaces decided by the interface decision section. The interface candidate selec...

Embodiment 3

[0141] In Embodiment 3, mobile communication device 101, mobile router 102, and mobile communication system 105 have the same configuration as Embodiment 2. Candidate interface selection section 111 of mobile communication device 101 in this embodiment selects first, second and third candidate interfaces of high score ranks based on the scores calculated in Embodiment 2. The network controller 203 sets the candidate interface with a priority order as shown in FIG. 25C and stores it in a candidate interface notification message, thereby sending it to the mobile router 102 through the public wireless interface 201 . Here W-CDMA is the first candidate interface, and IEEE802.11a is the second candidate interface. In FIG. 25C , its own identification code is set as a mobile communication device identifier 2501 , the external interface type selected as a candidate is set as an external candidate interface 2504 , and the selection order of the external interface is set as a priority ...

Abstract

A mobile communication device includes: a service type recording section (205) for recording characteristic of a service used by the mobile communication device; and an interface recording section (206) for recording the external connection interface type in the network and the characteristic. An interface decision section (207) selects at least one interface satisfying the service request and this is reported to a mobile router having an external connection interface. Thus, even when a change has occurred in the link state of the external interface of the mobile router, the mobile communication device can rapidly switch the external interface so as to continue the communication and can evade communication congestion between the mobile communication device and the mobile router during switching.

Description

technical field [0001] The present invention relates to a mobile router for implementing network-based movement, and a mobile communication device provided in the mobile router, in particular to a mobile communication device, a mobile router and a mobile communication system. The mobile communication system is based on mobile The information processed by the communication device adopts the most suitable external interface for connecting with the network. Background technique [0002] Recently, personal network devices have been expanding with the development of cellular phone networks and wireless LANs. In this case, consider a ubiquitous network that forms a network of everything around to achieve access anytime and anywhere. For example, it has been disclosed in the report document "Study Group on the Future Overview of Ubiquitous Network Technology"-toward realizing a network with anything at everywhere, June 11 2002, Information & Communication Policy Bureau of Ministry...
