WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD USING BLUETOOTH
First Claim
1. A wireless communication method comprising:
- causing a second wireless terminal having a control function with respect to a first wireless terminal to transmit a first control packet to the first wireless terminal referring to a priority table holding a transmission priority order for each kind of the packet to be transmitted to the first wireless terminal, the first control packet being a packet for receiving a first data packet from the first wireless terminal making Bluetooth communications;
causing the first wireless terminal to transmit the first data packet to the second wireless terminal in response to the first control packet;
causing the second wireless terminal to further transmit a second control packet for receiving a second data packet to the first wireless terminal according to the priority table after receiving the first data packet; and
causing the second wireless terminal to search a third wireless terminal according to the priority table after the reception of the second data packet from the first wireless terminal ends.

Abstract
A wireless communication apparatus which is capable of communicating with a first wireless terminal holding a first data packet by Bluetooth includes a search unit, a first transceiver transmitting, a first controller, and a scheduling unit. The search unit reserves a search, and executing the search. The first transceiver transmits the first and second control packets, and receives the first data packet and a second data packet. The first controller reserves a transmission of the second control packet to the first wireless terminal, the first controller giving instructions to transmit the second control packet to the first transceiver. The scheduling unit accepts the reservation from the first controller and the search unit, the scheduling unit preferentially allowing a transmission of the second control packet compared with the search, and allowing the search when no reservation of the transmission of the second control packet is made.

8. A wireless communication apparatus which is capable of communicating with a first wireless terminal holding a first data packet by Bluetooth, comprising:
-
a search unit reserving a search of a second wireless terminal different from the first wireless terminal, and executing the search when the reservation is allowed; a first transceiver transmitting the first and second control packets to the first wireless terminal, and receiving the first data packet and a second data packet following the first data packet from the first wireless terminal, the first data packet transmitted from the first transceiver giving a notification of a transfer start of the first data packet, the second control packet giving a notification of a transfer start of the second data packet; a first controller reserving a transmission of the second control packet to the first wireless terminal, the first controller giving instructions to transmit the second control packet to the first transceiver when the transmission of the second control packet is allowed; and a scheduling unit accepting the reservation from the first controller and the search unit, the scheduling unit preferentially allowing a transmission of the second control packet compared with the search, and allowing the search when no reservation of the transmission of the second control packet is made. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A wireless communication method comprising:
-
causing a first wireless terminal making a Bluetooth communication to set a data transfer allowable period to a second wireless terminal having a control function with respect to the first wireless terminal; causing the second wireless terminal to transmit a first control packet for receiving a first data packet from the first wireless terminal referring to a priority table holding a transmission priority rank for each kind of the packet with respect to a packet to be transmitted to the first wireless terminal within the data transfer allowable period; causing the first wireless terminal to transmit the first data packet to the second wireless terminal in response to the first control packet; causing the second wireless terminal to further transmit a second control packet for receiving a second data packet to the first wireless terminal according to the priority table after receiving the first data packet; and causing the second wireless terminal to search a third wireless terminal according to the priority table after the reception of the second data packet from the first wireless terminal ends, transmission of the first and second control packets and search of the third wireless terminal being carried out within the same data transfer allowable period. - View Dependent Claims (16, 17, 18, 19, 20)
