Command processing method and radio communication apparatus
First Claim
1. A command processing method for a radio LAN (Local Area Network) system which includes a plurality of terminals and at least one base apparatus and wherein a command issued from any of said terminals is received by said base apparatus and information is transmitted from said base apparatus to one or more of the plurality of terminals by radio communication between the terminals and said base apparatus, said method comprising the steps of:
- receiving commands issued from any of said terminals, said commands comprising both competitive commands and non-competitive commands;
determining whether the received command is a competitive command whose acceptance can result in a disturbance of information reception of any other of said terminals;
rejecting acceptance of the command if it is determined that said received command is a competitive command; and
issuing a notification of the rejection of the command to the terminal that has issued the command;
whereby the disturbance caused by an acceptance of a competitive command to other terminals that are under a receiving state is minimized.

Abstract
A command processing method for a radio LAN system composed of a plurality of terminals and at least one base apparatus is disclosed which prevents users of the terminals from suffering from confusion or conflict between them with regard to handling of a command issued from any of the terminals and from misunderstanding that the system has failed. When a channel changing command or a like command is issued from a terminal, the base apparatus determines whether or not the received command is a competitive command whose acceptance may result in the disturbance of reception of data of any other terminal. If the received command is a competitive command, then the base apparatus rejects the command and issues a notification of the rejection to the terminal which has issued the command. When a particular condition is satisfied such as when the priority of the terminal which has issued the command is higher than that of any other terminal receiving data, then the base apparatus may accept the command.

5. A radio communication apparatus for a radio LAN (Local Area Network) system that includes a plurality of terminals and at least one base apparatus wherein a command issued from any of said terminals is received by said base apparatus and information is transmitted from said base apparatus to the terminals by radio communication between the terminals and said base apparatus, said base apparatus comprising:
-
reception means for receiving commands issued from any of said terminals, said commands comprising both competitive commands and non-competitive commands;
discrimination means for determining whether the received command is a competitive command whose acceptance can result in a disturbance of reception of data of any other of said terminals, and further determining, based on a result of the determination whether the received command is the competitive command, and whether or not the command should be accepted; and
first transmission means for issuing, when said discrimination means determines that acceptance of the command should be rejected, a notification of the rejection of acceptance of the command to the terminal which has issued the command;
whereby the disturbance caused by an acceptance of a competitive command to other terminals that are under a receiving state is minimized. - View Dependent Claims (6, 7, 8)

9. A command processing method for a base apparatus connecting to a plurality of terminals wherein a command issued from any of said terminals is received by said base apparatus and information is transmitted from said base apparatus to one or more of the plurality of terminals, said method comprising the steps of:
-
receiving commands issued from any of said terminals, said commands comprising both competitive commands and non-competitive commands;
determining whether the received command is a competitive command whose acceptance can result in a disturbance of information reception of any other of said terminals;
rejecting acceptance of the command if it is determined that said received command is a competitive command; and
issuing a notification of the rejection of the command to the terminal that has issued the command;
whereby the disturbance caused by an acceptance of a competitive command to other terminals that are under a receiving state is minimized. - View Dependent Claims (10)

11. A base apparatus connecting to a plurality of terminals wherein a command issued from any of said terminals is received by said base apparatus and information is transmitted from said base apparatus to the terminals, said base apparatus comprising:
-
reception means for receiving commands issued from any of said terminals, said commands comprising both competitive commands and non-competitive commands;
determining means for determining whether the received command is a competitive command whose acceptance can result in a disturbance of reception of data of any other of said terminals;
rejecting means for acceptance of the command if it is determined that said received command is a competitive command; and
transmission means for issuing, when said discrimination means determines that acceptance of the command should be rejected, a notification of the rejection of acceptance of the command to the terminal which has issued the command;
whereby the disturbance caused by an acceptance of a competitive command to other terminals that are under a receiving state is minimized. - View Dependent Claims (12)

13. A base apparatus for communicating with at least a first terminal and a second terminal, each terminal operable to send a command to said base apparatus, comprising:
-
a reception section for receiving a first command from said first terminal;
a channel selector for selecting desired a information transmission channel in accordance with said first command received from the first terminal and for outputting video data and audio data transmitted via said selected information transmission channel;
a compression section for compressing said video data and audio data outputted from said channel selector;
a transmission section for transmitting said compressed video data and audio data to said first terminal; and
a control section for rejecting a second command from said second terminal when said reception section receives said second command while said transmission section is transmitting said compressed video data and audio data to said first terminal, whether said second command is a competitive command or is not a competitive command. - View Dependent Claims (14, 15)
