Abstract

A method for controlling a wireless router and a wireless router includes: detecting whether the wireless router has a connection with a terminal; and if the wireless router has no connection with any terminal, turning off the wireless router. By using the method for controlling a wireless router and the wireless router provided in embodiments of the present invention, whether the wireless router has a connection with a terminal may be detected; and the wireless router is turned off when the wireless router has no connection with any terminal. In this way, the wireless router may be automatically turned off in an idle state, which saves energy resources and avoids unnecessary consumption.

Claims

1. A method for controlling a wireless router, comprising:

detecting, by the wireless router, whether the wireless router has a connection with a terminal; and

if the wireless router has no connection with any terminal, turning off the wireless router by the wireless router.

2. The method according to claim 1, wherein the detecting, by the wireless router, whether the wireless router has a connection with the terminal comprises:

if the wireless router does not transfer data within a first preconfigured duration, performing connection detection on an IP address of the terminal that has no data transmission within a second preconfigured duration by the wireless router;

if a response is received, determining that the wireless router has a connection with the terminal by the wireless router;

if no response is received, determining that the wireless router has no connection with the terminal by the wireless router.

3. The method according to claim 2, wherein:

the detecting, by the wireless router, whether the wireless router has a connection with the terminal further comprises;

obtaining the IP address of the terminal that has no data transmission within the second preconfigured duration by the wireless router;

the obtaining the IP address of the terminal that has no data transmission within the second preconfigured duration by the wireless router comprises;

obtaining, by the wireless router, the IP address corresponding to the terminal from a data packet sent by a network side or the terminal; and

if no more data packet corresponding to the IP address is received within the second preconfigured duration, determining that the IP address is the IP address of the terminal that has no data transmission within the second preconfigured duration by the wireless router.

4. The method according to claim 2, wherein the performing connection detection on the IP address of the terminal that has no data transmission within the second preconfigured duration by the wireless router comprises:

performing a Packet Internet Grope test on the IP address of the terminal that has no data transmission within the second preconfigured duration by the wireless router.

5. The method according to claim 1, wherein the detecting, by the wireless router, whether the wireless router has a connection with the terminal comprises:

detecting whether a logical association between the wireless router and the terminal is set up on an air interface by the wireless router;

if the logical association exists, determining that the wireless router has a connection with the terminal by the wireless router;

if no logical association exists, determining that the wireless router has no connection with the terminal by the wireless router.

6. The method according to claim 1, wherein the turning off the wireless router by the wireless router if the wireless router has no connection with any terminal comprises:

if the wireless router has no connection with any terminal within a third preconfigured duration, turning off the wireless router by the wireless router.

7. A wireless router, comprising:

a detecting module, configured to detect whether the wireless router has a connection with a terminal; and

a closing module, configured to turn off the wireless router if the wireless router has no connection with any terminal.

8. The wireless router according to claim 7, wherein the detecting module is configured to:

if the wireless router does not transfer data within a first preconfigured duration, perform connection detection on an IP address of a terminal that has no data transmission within a second preconfigured duration;

if a response is received, it is detected that the wireless router has a connection with the terminal;

if no response is received, it is detected that the wireless router has no connection with the terminal.

9. The wireless router according to claim 8, further comprising:

a determining module, configured to;

obtain an IP address corresponding to the terminal from a data packet sent by a network side or the terminal;

if no more data packet corresponding to the IP address is received within the second preconfigured duration, it is detected that the IP address is the IP address of the terminal that has no data transmission within the second preconfigured duration.

10. The wireless router according to claim 7, wherein the detecting module is configured to:

detect whether a logical association between the wireless router and the terminal is established on an air interface;

if a logical association exists, it is detected that the wireless router has a connection with the terminal;

if no logical association exists, it is detected that the wireless router has no connection with the terminal.

11. The wireless router according to claim 7, wherein the closing module is configured to turn off the wireless router if the wireless router has no connection with any terminal within a third preconfigured duration.
