Abstract

Abstract A channel management apparatus provided for a plurality of master radio communication units (1₁.... 1 n , 2₁.... 2 n ) which perform communication by selecting as desired one or more of a plurality of channels (1ch..... nch) that are respectively assigned to a plurality of radio communication slave units. This apparatus is provided with a shared storage device (3) which is capable of being set to each master unit (2₁.....2 n ) and which contains items of data on registered channels (1ch..... nch) which correspond to all of the channels used by the master units, and a plurality of groups of devices incorporated in the master units. Each of the groups of devices includes: a setting device (5) for manually setting the channels to be used by a corresponding one of the master units; a display device (6) for displaying the channels used by the master units; a channel data processing device (7) adapted to make the display device (6) display data on the register channel by reading the data from the storage device (3) which has been set, the data processing device (7) updating the data on the registered channels in the storage device (3) in accordance with the data on the channels used by the master unit supplied from the setting means (5); and a channel selecting device (8) adapted to select, in accordance with the data on the channels to be used, channels through which the communication is performed.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 295 words
A channel management apparatus in a radio communication system provided for a plurality of radio communication master units (20) which perform communication by selecting as desired one or more of a plurality of channels that are respectively assigned to a plurality of radio communication slave units (10), the apparatus comprising: - a shared storage device (3; 29) capable of being set to each master unit (2₁..... 2 n ; 20) and adapted to contain data on registered channels (1ch.... nch) which corres­pond to all of the channels used by the master units; - and a pluraltiy of groups of means incorporated in the master units (2₁....2 n ; 20) wherein each of the groups of means includes: - setting means (5; 26) for manually setting channels used by a corresponding one of the master units (2₁..... 2 n ; 20) and for cancelling channels to be cancelled; - display means (6; 23, 24) for displaying usable or unusable channels and the channels used by the master unit (2₁....2 n ; 20); - data processing means (7; 201 - 205) adapted to make the display means (6; 23, 24) display data on the registered channels as usable or unusable channels by reading the data on the registered channels from the storage device (3, 20) which has been set, the data processing means (7; 201 - 205) updating the data on the registered channels in the storage device (3; 29) in accordance with the data on the channels used for the master unit (20) and the data on the channel to be cancelled supplied from the setting means (3; 26); and - channel selecting means (8) adapted to select, in accordance with the data on the channels to be used, channels through which the communication is performed.
Claim 2
Dependent Claim 295 words
A channel management apparatus in a radio communication system provided for a plurality of radio communication master units (20) which perform communication by selecting as desired one or more of a plurality of channels that are respectively assigned to a plurality of radio communication slave units (10), the apparatus comprising: - a shared storage device (3; 29) capable of being set to each master unit (2₁..... 2 n ; 20) and adapted to contain data on registered channels (1ch.... nch) which corres­pond to all of the channels used by the master units; - and a pluraltiy of groups of means incorporated in the master units (2₁....2 n ; 20) wherein each of the groups of means includes: - setting means (5; 26) for manually setting channels used by a corresponding one of the master units (2₁..... 2 n ; 20) and for cancelling channels to be cancelled; - display means (6; 23, 24) for displaying usable or unusable channels and the channels used by the master unit (2₁....2 n ; 20); - data processing means (7; 201 - 205) adapted to make the display means (6; 23, 24) display data on the registered channels as usable or unusable channels by reading the data on the registered channels from the storage device (3, 20) which has been set, the data processing means (7; 201 - 205) updating the data on the registered channels in the storage device (3; 29) in accordance with the data on the channels used for the master unit (20) and the data on the channel to be cancelled supplied from the setting means (3; 26); and - channel selecting means (8) adapted to select, in accordance with the data on the channels to be used, channels through which the communication is performed.
Claim 3
Dependent Claim 39 words
The channel management apparatus according to claim 1, wherein each of the groups of means includes a non-volatile memory (204) for storing data on channels used by the corresponding one of the master units (2₁..... 2 n ; 20).
Claim 4
Dependent Claim 24 words
The channel management apparatus according to claim 1 or 2, wherein the channel data processing means (7; 201 - 205) comprises a CPU (201).
Claim 5
Dependent Claim 25 words
The channel management apparatus according to any of claims 1 to 3, wherein the storage device (3; 29) is a card type of storage device.
