Communication apparatus preventing communication interference
View Patent ↗A game apparatus according to a preferred embodiment includes a first wireless communication module and a second wireless communication module. The first wireless communication module performs communication utilizing Bluetooth protocols, whereas the second wireless communication module performs communication utilizing IEEE protocols. The first radio communication module and the second radio module have a common reference communication cycle, and each communicates in communication cycles of an integral multiple of the reference communication cycle. A control unit sets offset time between the start time of a communication by the first wireless communication module until the start time of a communication by the second wireless communication module. In so doing, the control unit monitors the communication load of the first wireless communication module and sets the offset time based on a monitored result.
1. A communication terminal apparatus, comprising:
a first wireless communication module which executes communication in a predetermined frequency band, using a first communication scheme;
a second wireless communication module which executes communication in the predetermined band, using a second communication scheme that differs from the first communication scheme; and
a control unit which selects one of a plurality of communication modes, including a periodical communication mode in which said first wireless communication module and said second wireless communication module execute communication in accordance with a reference communication cycle common thereto, and a non-periodic communication mode in which said first wireless communication module executes communication on a non-periodic basis.
2. The communication terminal apparatus according to claim 1 , wherein the control unit sets mode information for identifying a communication mode for said first wireless communication module and said second wireless communication module.
3. The communication terminal apparatus according to claim 1 , wherein said first wireless communication module conveys a start timing in a communication cycle of said first wireless communication module to said second wireless communication module.
4. The communication terminal apparatus according to claim 3 , wherein said second wireless communication module determines a start timing of a prohibited communication period of said second wireless communication module based on the conveyed start timing in the communication cycle of said first wireless communication module.
5. The communication terminal apparatus according to claim 3 , wherein said first wireless communication module sends a status signal indicating a status of execution of communication in said first wireless communication module to said second wireless communication module.
6. The communication terminal apparatus according to claim 5 , wherein, when the status signal indicates that said first wireless communication module executes communication in the non-periodic communication mode, said second wireless communication module stops communication.
7. The communication terminal apparatus according to claim 5 , wherein, in the periodic communication mode, said second wireless communication module executes communication using the conveyed start timing in the communication cycle of said first wireless communication module, regardless of the status signal.
8. The communication terminal apparatus according to claim 1 , wherein the periodic communication mode is a communication mode selected while a game is being executed and the non-periodic communication mode is a communication mode selected while audio communication is being executed.
9. A method for controlling communications of a first wireless communication module which executes communication in a predetermined frequency band, using a first communication scheme, and a second wireless communication module which executes communication in the predetermined band, using a second communication scheme differing from the first communication scheme, the method including:
selecting one of a plurality of communication modes, including a periodical communication mode in which said first wireless communication module and said second wireless communication module execute communication in accordance with a reference communication cycle common thereto, and a non-periodic communication mode in which said first wireless communication module executes communication on a non-periodic basis; and
controlling the execution of communication in said first wireless communication module and said second wireless communication module in accordance with the selected communication mode.
10. A computer program embedded on a non-transitory computer readable recording medium and implementing, on a computer for controlling communications of a first wireless communication module which executes communication in a predetermined frequency band, using a first communication scheme, and a second wireless communication module which executes communication in the predetermined band, using a second communication scheme differing from the first communication scheme, the modules comprising:
a module configured to select one of a plurality of communication modes, including a periodical communication mode in which said first wireless communication module and said second wireless communication module execute communication in accordance with a reference communication cycle common thereto, and a non-periodic communication mode in which said first wireless communication module executes communication on a non-periodic basis; and
a module to control the execution of communication in said first wireless communication module and said second wireless communication module control in accordance with the selected communication mode.
11. The computer readable recording medium having embedded thereon the program according to claim 10 .
