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.

First claim

What is claimed is:

1 . A method for waking up an access point (AP) device, comprising:
receiving, by a wakeup server, an AP activation request sent by a terminal device, wherein the AP activation request comprises an identity of the terminal device; determining a target AP device according to the AP activation request; acquiring a status of the target AP device; in response to the target AP device being in a sleep state, sending a wakeup request to the target AP device, so that the target AP device switches to an awake state according to the wakeup request; and sending a first AP activation success response to the terminal device.

2 . The method according to claim 1 , wherein the method further comprises:
in response to the target AP device being in an awake state, sending a second AP activation success response to the terminal device.

3 . The method according to claim 2 , 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.

4 . The method according to claim 3 , 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.

5 . The method according to claim 4 , wherein:
the registration request further comprises location information of the first AP device; the AP activation request comprises the location determining information; and 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.

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:
a receiver, configured to receive an AP activation request sent by a terminal device, wherein the AP activation request comprises an identity of the terminal device; a processor, configured to:
determine a target AP device according to the AP activation request; and
acquire a status of the target AP device; and
a transmitter, configured to:
in response to the target AP device being in a sleep state, send a wakeup request to the target AP device, so that the target AP device switches to an awake state according to the wakeup request; and
send a first AP activation success response to the terminal device.

10 . The wakeup server according to claim 9 , wherein the transmitter is further configured to:
in response to the target AP device being in an awake state, send a second AP activation success response to the terminal device.

11 . The wakeup server according to claim 9 , wherein:
the receiver is further configured to receive a registration request of a first AP device, wherein the first AP device is an AP device 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 the transmitter is further configured to send registration response information to the first AP device.

12 . The wakeup server according to claim 11 , 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 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.

13 . The wakeup server according to claim 12 , wherein:
the registration request further comprises location information of the first AP device, the AP activation request comprises the location determining information, and the processor is further configured to:
determine a to-be-selected AP device;
determine, 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
determine, 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.

14 . A wakeup server, comprising:
means for receiving an AP activation request sent by a terminal device, wherein the AP activation request comprises an identity of the terminal device; means for determining a target AP device according to the AP activation request; and means for acquiring a status of the target AP device; means for sending a wakeup request to the target AP device in response to the target AP device being in a sleep state, so that the target AP device switches to an awake state according to the wakeup request; and means for sending a first AP activation succes
