Abstract:
1. A radio communication system comprising: a plurality of first communication devices; a second communication device; and a portable terminal holding radio communication with one of said first communication devices and said second communication device, wherein said second communication device includes: first communication means for communicating with one of said first communication devices; second communication means for communicating with said portable terminal; and third communication means for communicating with a communication device other than the communication device communicating with the first communication means; and control means for controlling said first communication means, said second communication means and said third communication means, said control means includes: means for controlling said third communication means so as to receive a connection request to said portable terminal from said other communication device; and means for controlling said second communication means so as to transmit said connection request to said portable terminal, said portable terminal includes: first communication means for communicating with said first communication device; second communication means for communicating with said second communication device; search means for searching for the communicable first communication device from said plurality of first communication devices in response to the connection request from said second communication device; and control means for controlling said first communication means and said second communication means, said control means including means for controlling said first communication means and said second communication means so as to selectively execute one of a first communication mode for communicating with said other communication device via said second communication device and a second communication mode for communicating with said other communication device via said communicable first communication device and said second communication device on the basis of a search result of said search means, said first communication device includes: first communication means for communicating with said portable terminal; second communication means for communicating with said second communication device; and control means for controlling said first communication means and said second communication means, said control means includes: means for controlling said first communication means so as to transmit information representing that communication can be held, to said portable terminal in response to the search result of said search means; and means for controlling said first communication means and said second communication means so as to hold communication between said portable terminal and said second communication device when said second communication mode is selected, the control means of said portable terminal further includes means for controlling said first communication means and said second communication means so as to hold communication between said first communication device and said second communication device when said second communication mode is selected, and the control means of said second communication means further includes: means for controlling said second communication means and said third communication means so as to hold communication between said portable terminal and said other communication device when said first communication mode is selected; and means for controlling said first communication means and said third communication means so as to hold communication between said first communication means and said other communication device when said second communication mode is selected.
