Abstract

A wireless channel selecting apparatus includes: a memory to store data indicating whether each of a plurality of wireless speech channels can be selected or not; and a selector to select the wireless speech channels to be used on the basis of the data stored in the memory. The number of times at which the wireless channels have been determined to be disabled is stored as data in the memory. The selection of the wireless speech channels which have been decided to be disabled is inhibited. The wireless speech channels other than the inhibited channels are selected as speech channels to be used. The inhibition of the channel selection is released after the elapse of a predetermined time from the inhibition.

Claims

1. A communication channel selecting method of selecting one of a plurality of communication channels, comprising the steps of:

discriminating which of the plurality of communication channels are in a first state or a second state;

inhibiting a selection of one of the plurality of communication channels when the one of the plurality of communication channels is in the first state or the second state;

selecting the plurality of communication channels to be used for a communication;

releasing, in a case where the one of the plurality of communication channels is in the first state, the inhibition if a first period elapses after inhibiting the selection; and

releasing, in a case where the one of the plurality of communication channels is in the second state, the inhibition if a second period elapses after inhibiting the selection,

wherein the first state is a state in which the number of times continuously discriminated as the one of the plurality of communication channels should not be used reaches a first value, and the second state is a state in which the accumulated number of times discriminated as the one of the plurality of communication channels should not be used reaches a second value.

2. A method according to claim 1, wherein said communication channels include wireless communication channels.

3. A communication channel selecting method comprising the steps of:

discriminating states of a plurality of communication channels;

inhibiting a selection of the plurality of communication channels according to a discrimination in said discriminating step;

selecting an uninhibited one of the plurality of communication channels to be used for a communication according to the discrimination in said discriminating step; and

performing a display according to the discrimination in said discriminating step before the selection of all of the plurality of communication channels is inhibited, according to an excess of the number of the plurality of communication channels to which the selection is inhibited over a predetermined value.

4. A method according to claim 3, wherein the plurality of communication channels include wireless communication channels.

5. A method according to claim 3, wherein the display in said performing step is performed according to a number of the plurality of communication channels having the selection inhibited.

6. A method according to claim 3, wherein a visual display is performed in said performing step.

7. A communication channel selecting method comprising the steps of:

discriminating whether a communication using one of a plurality of communication channels succeeded or failed;

accumulating the number of times that the communication using the one of the plurality of communication channels failed;

counting the number of times that the communication using the one of the plurality of communication channels continuously failed; and

inhibiting the communication using the one of the plurality of communication channels, when the accumulated number of times that the communication failed reaches a first value and the number of times that the communication continuously failed reaches a second value smaller than the first value.

8. A method according to claim 7, wherein the plurality of communication channels include wireless communication channels.

9. A communication channel selecting apparatus comprising:

discriminating means for discriminating states of a plurality of communication channels;

inhibiting means for inhibiting a selection of the plurality of communication channels according to a discrimination by said discriminating means;

selecting means for selecting an uninhibited one of the plurality of communication channels to be used for a communication according to the discrimination by said discriminating means; and

display means for performing a display according to the discriminating by said discriminating means before the selection of all of the plurality of communication channels is inhibited, according to an excess of the number of the plurality of communication channels to which the selection is inhibited over a predetermined value.

10. An apparatus according to claim 9, wherein the plurality of communication channels include wireless communication channels.

11. An apparatus according to claim 9, wherein said display means performs the display according to the number of the plurality of communication channels for which the selection is inhibited.

12. An apparatus according to claim 9, wherein said display means performs a visual display.
