Abstract

Embodiments provide a waking-up system made up of an access point (AP) device, a terminal device and a wakeup server. The wakeup server comprises a receiving unit, configured to receive an AP activation request sent by the terminal device, where the AP activation request includes an identity of the terminal device. Also included a determining unit, configured to determine a target AP device according to the AP activation request. Also included is an acquiring unit, configured to acquire a status of the target AP device, and a sending unit, configured to send a wakeup request to the target AP device, wherein the sending unit is further configured to send a first AP activation success response to the terminal device.

determining, in the candidate target AP device, that former T AP devices having optimal quality of service are target AP devices, wherein T is less than or equal to a threshold of a quantity of APs that are to be woken up.

6. The method according to claim 1, wherein before receiving an AP activation request sent by a terminal device, the method further comprises:

receiving a registration request of a first AP device, wherein the first AP device is in a management range of the wakeup server, and the registration request comprises an identity of the first AP device and a wakeup address of the first AP device; and

sending registration response information to the first AP device.

7. The method according to claim 6, wherein:

the AP activation request further comprises one or more of a target AP device list and location determining information; and

the target AP device list records an identity of a target AP device, and the location determining information comprises location information of the terminal device, a wakeup distance range, and a maximum quantity of APs that are to be woken up.

8. The method according to claim 7, wherein:

the registration request further comprises location information of the first AP device;

the AP activation request comprises the location determining information; and

the determining the target AP device according to the AP activation request comprises;

determining a to-be-selected AP device;

determining, in the to-be-selected AP device according to the location information of the terminal device and location information, which is recorded by the wakeup server, of an AP device, that an AP device that is away from the terminal device by a distance within the wakeup distance range is a candidate target AP device; and

determining, in the candidate target AP device, that former T AP devices having optimal quality of service are target AP devices, wherein T is less than or equal to a threshold of a quantity of APs that are to be woken up.

9. A wakeup server, comprising:
