Abstract

A base station apparatus includes a primary transceiver and a processing unit for controlling the primary transceiver to communicate with the related communication apparatuses during a full scan period. The full scan period includes at least one sub-scan period, during one sub-scan period, the processing unit performs a primary communication test between the primary transceiver and each of the related communication apparatuses, judges whether the primary communication test has failed, and determines the corresponding communication apparatus as a failed communication apparatus if the primary communication test has failed. The processing unit further performs a secondary communication test between the primary transceiver and each failed communication apparatus in the previous sub-scan period during a next sub-scan period.

Claims

1. A base station apparatus for communicating with a plurality of communication apparatuses, the base station apparatus comprising:

a primary transceiver; and

a processing unit for controlling the primary transceiver to communicate with the related communication apparatuses during a full scan period;

wherein the full scan period comprises at least one sub-scan period, during one sub-scan period, the processing unit performs a primary communication test between the primary transceiver and each of the related communication apparatuses, judges whether the primary communication test has failed, and determines the corresponding communication apparatus as a failed communication apparatus if the primary communication test has failed;

the processing unit further performs a secondary communication test between the primary transceiver and each failed communication apparatus in the previous sub-scan period during a next sub-scan period.

2. The base station apparatus of claim 1, wherein the processing unit judges whether the secondary communication test has failed, determines the corresponding communication apparatus as the failed communication apparatus, and repeatedly performs the secondary communication test if the secondary communication test has failed.

3. The base station apparatus of claim 1, wherein if the primary communication test is successful, the full scan period is completed.

4. The base station apparatus of claim 1, wherein if the secondary communication test is successful, the full scan period is completed.

5. The base station apparatus of claim 1, wherein during a first sub-scan period, the processing unit performs the primary communication test between the primary transceiver and each of the plurality of communication apparatuses.

6. The base station apparatus of claim 5, further comprising a storage unit for storing a plurality of identification (ID) codes respectively assigned to the plurality of communication apparatuses, wherein the processing unit is used for controlling the primary transceiver to transmit a request signal to each of the plurality of communication apparatuses, and ready to receive a response signal from each of the plurality of communication apparatuses in response to the request signal;

each response signal includes the ID code of corresponding communication apparatus;

the processing unit judges whether each ID code included in each response signal matches with each ID code stored in the storage unit to judge whether the primary communication test has failed.

7. The base station apparatus of claim 6, wherein the processing unit controls the primary transceiver to transmit the request signal every first predetermined time period.

8. The base station apparatus of claim 7, wherein the processing unit further judges whether the primary transceiver has received the response signal during a second determined time period after the primary transceiver has transmitted the request signal;

if it is determined that the primary transceiver has not received the response signal, the processing unit controls the primary transceiver to stop searching for the response signal.

9. The base station apparatus of claim 6, wherein each of the communication apparatuses includes a secondary transceiver, the processing unit receives the response signal from the secondary transceiver of each communication apparatus in response to the request signal.

10. A communication method for performing communication operations between a base station apparatus and a plurality of communication apparatuses, the base station apparatus comprises a primary transceiver, the method comprising:

controlling the primary transceiver to communicate with the related communication apparatuses during a full scan period, the full scan period comprises at least one sub-scan period;

performing a primary communication test between the primary transceiver and each of the related communication apparatuses during one sub-scan period;

judging whether the primary communication test has failed;

determining the corresponding communication apparatus as a failed communication apparatus if the primary communication test has failed; and

performing a secondary communication test between the primary transceiver and each failed communication apparatus in the previous sub-scan period during a next sub-scan period.

11. The communication method of claim 10, further comprising:

judging whether the secondary communication test has failed; and

determining the corresponding communication apparatus as the failed communication apparatus and repeatedly performing the secondary communication test if the secondary communication test has failed.

12. The communication method of claim 10, wherein if the primary communication test is successful, the full scan period is completed.

13. The communication method of claim 10, wherein if the secondary communication test is successful, the full scan period is completed.

14. The communication method of claim 10, comprising:

performing the primary communication test between the primary transceiver and each of the plurality of communication apparatuses during a first sub-scan period.

15. The communication method of claim 10, wherein the step of performing the primary communication test comprising:

providing a storage unit to store a plurality of identification (ID) codes respectively assigned to the related communication apparatuses; and

controlling the primary transceiver to transmit a request signal to each of the related communication apparatuses and ready to receive a response signal from each of the related communication apparatuses in response to the request signal;

each response signal includes the ID code of corresponding communication apparatus.

16. The communication method of claim 15, wherein the step of judging whether the primary communication test has failed comprising:

judging whether each ID code included in each response signal matches with each ID code of the related communication apparatuses stored in the storage unit to judge whether the primary transceiver has successfully received the response signal from all the related communication apparatuses.

17. The communication method of claim 16, wherein the step of performing the secondary communication test comprising:

controlling the primary transceiver to transmit a request signal to each failed communication apparatus and ready to receive a response signal from each failed communication apparatus in response to the request signal.

18. The communication method of claim 17, wherein the step of judging whether the secondary communication test has failed comprising:

judging whether each ID code included in each response signal matches with each ID code of the failed communication apparatuses stored in the storage unit to judge whether the primary transceiver has successfully received the response signal from all the failed communication apparatuses.

19. The communication method of claim 17, wherein the step of performing the primary communication test or the secondary communication test further comprising:

controlling the primary transceiver to transmit the request signal every first predetermined time period;

judging whether the primary transceiver has received the response signal during a second determined time period after the primary transceiver has transmitted the request signal; and
