Embodiment Construction

[0025] Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram describing a schematic structure of a multimedia integrated network innovated by radio access technology (MIRAI) embodying the present invention. In FIG. 1 , the MIRAI network 10 is composed of different radio access networks (RAN) 11 , the Internet 12 and multimode wireless terminals (MUT: Multiservice User Terminal) 13 . Different radio access networks 11 include a plurality of different radio access networks. In this embodiment, a plurality of different wireless access networks are composed of a PHS (Personal Handyphone System) network 11a, a wireless LAN (WLAN: Wireless Local Area Network) 11b, a paging network (duplex paging system) 11c, a cellular phone The net 11d etc. are composed. In other words, in different radio access networks 11 there are multiple service areas of the respective networks 11a-11d.

Abstract

A session control method for radio terminals that implements a Multimedia Integrated network by Radio Access Innovation (MIRAI) such that selection of a radio access network does not impose a burden on each of the radio access networks, and an interface setup method for setting up IP connection quickly during switching of the radio access network. The Multimedia Integrated network by Radio Access Innovation (MIRAI) 10 includes heterogeneous radio Access networks 11, Internet 12 and multimode radio terminals 13, and the heterogeneous radio access networks 11 includes a PHS network 11a, a wireless LAN 11b, a paging network 11c, and a cellular phone network 11d. The Internet 12 includes a CCN server 12a, which sends sessionrelated information to the radio terminal 13 via the paging network 11c. The radio terminal 13 selects a radio IF and application that are appropriate for communication based on the session-related information, and establishes a session.

Description

technical field [0001] The invention relates to a wireless terminal session control and interface establishment method. Background technique [0002] At present, a multimedia integrated network (MIRAI) using radio access innovation (Radio Access Innovation) has been proposed. The multimedia integrated network (Multimedia Integrated network) connects multiple different radio access networks (RAN), such as for example through public The core network connects the wireless LAN and the PHS, and enables seamless communication between these different wireless access networks (Non-Patent Reference 1). [0003] Regarding the structure of MIRAI, MIRAI includes a high-functionality public core network, a signaling network, and software defined radio (SDR) terminals or multimode wireless terminals. It should be appreciated that the multimode wireless terminal includes multiple interfaces and applications so that it uses a unique ID (number or URI, etc.) to designate the terminal when i...
