Abstract: The present invention is a wireless communications system for simultaneously establishing a basic access network and a wireless access network using at least two kinds of wireless communication networks. The basic access network executes signaling communication in which communication is controlled so as to be continuously switched, whereas the wireless access network executes data communications other than the signaling communication. According to the system of the present invention, networks can be continuously switched by setting multicast for temporarily flowing data to the basic access network.

This arrangement makes it possible to connect between terminals by a media application on peer to peer.

Abstract: A data communication method and apparatus for a mobile network. A destination foreign agent (FA2) recognizes a MAC address of an MN. The FA2 registers the MAC address of the MN in a handoff request message (FHReq), and the FA2 feeds the FHReq onto a transfer network. Each of foreign agents (FAs) receives the FHReq, registers an IP address corresponding to the MAC address in the FHReq when the MAC address is registered in a binding list of the FAs themselves, and feeds the IP address onto the transfer network. The FA2 receives the FHReq, and temporarily registers the MAC address and the IP address in the binding list of the FA2 itself. The FA2 transfers data sent from a homw agent (HA) to the MN, based on the information which has been temporarily registered.

Abstract: Disclosed are elastomeric compounds including an elastomer and a silicon-treated carbon black, and optionally including a coupling agent. The elastomeric compound exhibits poorer abrasion resistance in the absence of a coupling agent, lower hysteresis at high temperature and comparable or increased hysteresis at low temperature compared to an elastomer containing an untreated carbon black. A variety of elastomers and formulations employing such elastomers are contemplated and disclosed. Elastomeric compounds incorporating an elastomer and an oxidized, silicon-treated carbon black are also disclosed. Also disclosed are methods for preparing elastomers compounded with the treated carbon black.

Abstract: In a multiservice wireless communication system according to the present invention, a location manager 47 of a multiservice terminal 140 detects its own position with a GPS receiver interface 49. The location manager sends the detected positional information to a management server 110 via a common-signaling wireless network base station 100 in which respective multiple service zones serviced by multiple wireless systems overlap in a common-signaling wireless zone and acquires information on available wireless systems as a response to that. A network selecting section 44 selects a wireless system that most matches selecting conditions from the acquired available wireless systems and performs communication via the interfaces 40 and 41 that operate the selected wireless system.
