PROBLEM TO BE SOLVED: To enable a terminal station C to communicate by allowing a terminal station A to send hopping pattern(HP) information control data, when terminal stations A and B under communication through the use of a frequency hopping system receive control information from the terminal station C. SOLUTION: A terminal station A trying to start communication outputs an HP acquiring request 1201 to a centralized control station to obtain HP information 1202 and outputs a connecting request to a terminal station B. The terminal station A receiving connection confirmation 1204 outputted from the terminal station B reports connection completion to the centralized control station and transmits and receives data 1206 between with the terminal station B. When a terminal station C outputs the HP acquiring request 1201, the centralized control station gives common HP information 1202 to the terminal station C, which sends communication request control data 1207 to the terminal station A. The terminal station A sends HP information control data 1208 to the terminal station C to permit interrupting of communication, and the terminal station C is connected to the terminal station A to transmit and receive data 1206. The terminal station B suspends communication and only follow up HP to prepare the restart of communication with the terminal station A. |
