Abstract

A method for adjusting transmission power of a gateway device includes acquiring an access device identity, acquiring a predetermined wireless transmission power corresponding to the access device identity, and adjusting a current transmission power of the gateway device according to the predetermined wireless transmission power.

Claims

1. A method for adjusting transmission power of a gateway device, comprising:

acquiring an access device identity;

acquiring a predetermined transmission power corresponding to the access device identity;

sending a transmission power adjustment request to an access device corresponding to the access device identity; and

adjusting a current transmission power of the gateway device according to the predetermined transmission power based on a response to the transmission power adjustment request received from the access device.

2. The method according to claim 1, wherein acquiring the predetermined transmission power includes inquiring at least one saved access device identity and at least one saved predetermined transmission power corresponding to the at least one saved access device identity, to acquire the predetermined transmission power corresponding to the acquired access device identity.

3. The method according to claim 1, wherein:

acquiring the access device identity includes acquiring two or more access device identities, and

acquiring the predetermined transmission power includes;

inquiring priorities corresponding to the two or more access device identities; and

acquiring the predetermined transmission power corresponding to the access device identity having a highest priority.

4. The method according to claim 3, wherein inquiring the priorities includes inquiring from saved access device identities and saved priorities corresponding to the saved access device identities.

5. The method according to claim 3, wherein inquiring the priorities includes:

acquiring a current time;

acquiring a priority correspondence relationship corresponding to the current time, the priority correspondence relationship being a correspondence relationship between the access device identities and the priorities; and

inquiring the priorities from the priority correspondence relationship.

6. The method according to claim 1, wherein acquiring the access device identity includes acquiring, after an access device is successfully connected to the gateway device, the access device identity of the access device.

7. The method according to claim 1, wherein acquiring the access device identity includes acquiring the access device identity of each access device connected to the gateway device at every predetermined time interval.

8. The method according to claim 1, wherein the transmission power adjustment request is a first transmission power adjustment request, and adjusting the current transmission power includes:

sending a second transmission power adjustment request to an administrator device preset by a user for responding to the second transmission power adjustment request, the administrator device being configured to return an adjustment response to the gateway device according to the second transmission power adjustment request; and

adjusting, if the adjustment response indicates that a transmission power adjustment is allowed, the current transmission power to the predetermined transmission power.

9. A gateway device for adjusting transmission power, comprising:

a processor; and

a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to;

acquire an access device identity;

acquire a predetermined transmission power corresponding to the access device identity;

send a transmission power adjustment request to an access device corresponding to the access device identity; and

adjust a current transmission power of the gateway device according to the predetermined transmission power based on a response to the transmission power adjustment request received from the access device.

10. The gateway device according to claim 9, wherein the instructions further cause the processor to inquire at least one saved access device identity and at least one saved predetermined transmission power corresponding to the at least one saved access device identity, to acquire the predetermined transmission power corresponding to the acquired access device identity.

11. The gateway device according to claim 9, wherein the instructions further cause the processor to:

acquire two or more access device identities;

inquire priorities corresponding to the two or more access device identities; and

acquire the predetermined transmission power corresponding to the access device identity having a highest priority.

12. The gateway device according to claim 11, wherein the instructions further cause the processor to inquire from saved access device identities and saved priorities corresponding to the saved access device identities.

13. The gateway device according to claim 11, wherein the instructions further cause the processor to:

acquire a current time;

acquire a priority correspondence relationship corresponding to the current time, the priority correspondence relationship being a correspondence relationship between the access device identities and the priorities; and

inquire the priorities from the priority correspondence relationship.

14. The gateway device according to claim 9, wherein the instructions further cause the processor to acquire, after an access device is successfully connected to the gateway device, the access device identity of the access device.

15. The gateway device according to claim 9, wherein the instructions further cause the processor to acquire the access device identity of each access device connected to the gateway device at every predetermined time interval.

16. The gateway device according to claim 9, wherein the transmission power adjustment request is a first transmission power adjustment request, and the instructions further cause the processor to:

send a second transmission power adjustment request to an administrator device preset by a user for responding to the second transmission power adjustment request, the administrator device being configured to return an adjustment response to the gateway device according to the second transmission power adjustment request; and

adjust, if the adjustment response indicates that a transmission power adjustment is allowed, the current transmission power to the predetermined transmission power.

17. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor in a gateway device, cause the gateway device to:

acquire an access device identity;

acquire a predetermined transmission power corresponding to the access device identity;

send a transmission power adjustment request to an access device corresponding to the access device identity; and

adjust a current transmission power of the gateway device according to the predetermined transmission power based on a response to the transmission power adjustment request received from the access device.
