摘要:
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.

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. In the basic access network, there are executed signaling communication for obtaining available network information based on the position information of a terminal and communication by SIP (Session Initiation Protocol) for executing exchange of a subscribe request signal between terminals and negotiation of communication. This arrangement makes it possible to connect between terminals by a media application on peer to peer.

The present invention is intended to provide, for a wireless communication system originally having a calling function, a wireless communication system enabling an audio communication service or the like which requires a calling function, and to provide a wireless communication system which reduces power consumption of a wireless terminal when it is in a standby mode. A communication party, which is a calling side, a network to which the communication party is connected, and a wireless LAN base station, a pager base station, and a pager controller which are connected to the network, and a PC, which is a wireless communication terminal, constitute the present invention. The PC includes a wireless LAN card and a pager card 2. This forms the present invention.
摘要:
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.
