Row continues to execute step S210.
Wherein, cache-time referred to from the last time for sending the timing of Beacon start of heading and undergoing altogether.Setting time
Threshold value, which is equivalent to, defines that can at most pass through several intervals Beacon just send Beacon message.The step refers to, even if slow
It deposits capacity and has not been reached yet given threshold, but if cache-time is longer, and be more than setting time threshold value, will just it delay
All data deposited are sent to WIFI module 120, and in other words, the adjacent time sent between Beacon message twice cannot be too
It is long, data are not sent to WIFI module 120 to avoid because of the long period, and influence the normal operation of WIFI module 120.
It further, can also include: the setting time threshold value obtained after extending before step S250.Also, step
S250 are as follows: judge cache-time whether be more than extend after setting time threshold value, if so, execute step S240, otherwise execute step
Rapid S250.Therefore, the present embodiment enables wireless router 200 to cache the longer time, to further decrease WIFI module
120 receive the frequency of data in a power-save mode.
It further include following before step S230 in one of the embodiments, in above-mentioned wireless router operation method
Step please refers to Figure 11.
Step S220 obtains the interval Beacon after extending.
Also, step S240 is step S241, and the data in caching are passed through according to the interval Beacon after extension
Beacon message is sent to WIFI module 120.
Wherein, the interval Beacon refer to conventional wireless router it is adjacent twice send Beacon message between time between
Every in other words, traditional wireless router just sends a Beacon message every the interval Beacon.In the present embodiment, quite
In the sending cycle for extending Beacon message.Data in caching are reported according to the interval Beacon after extension by Beacon
Text is sent to WIFI module 120, in other words, may just send one behind the interval Beacon after several extensions in the present embodiment
Secondary Beacon message, for example, traditional wireless router 200 sends a Beacon message, and this implementation every 100ms
100ms is not only extended for 300ms (being divided into 300ms between the Beacon after extending) in mode, but also sends Beacon every time
The time of message is not fixed, it may be possible to cross 600ms (interval Beacon after having crossed 2 extensions) and just send
Beacon message, or crossed 900ms (interval Beacon after having crossed 3 extensions) and just sent Beacon message, as long as slow
The capacity of deposit data is more than given threshold.
It can be seen that being just to send a Beacon report behind the interval Beacon after have passed through several extensions in the present embodiment
Text, to further reduced the frequency of Beacon message transmission.Since WIFI module 120 can periodically listen to Beacon report
Text, therefore, the frequency that Beacon message is sent reduce, so that it may the frequency that WIFI module 120 receives Beacon message is reduced,
To reduce the power consumption of WIFI module 120 in a power-save mode.
It should be noted that in other embodiments, being also possible to only extend the interval Beacon, to reduce Beacon report
The frequency that text is sent.
Above-mentioned steps S210 specifically includes the following contents in one of the embodiments, please refers to Figure 12.
Step S211 receives the data from server 300.
Step S212 judges whether above-mentioned data are multicast message or broadcasting packet, if so, step S213 is executed, otherwise,
Execute step S214.
Wherein, if so, referring to that above-mentioned data are multicast message or broadcasting packet.Otherwise, refer to above-mentioned data neither group
Casting text is not again broadcasting packet.
Above-mentioned data are not placed in caching by step S213.
Wherein, above-mentioned data are not placed in caching, above-mentioned data will not be sent to WIFI module after representative
120.Further, step S213 is specifically as follows: above-mentioned data not being placed in caching, while judging that above-mentioned data are
ARP (Address Resolution Protocol, address resolution protocol) request or DHCP (Dynamic Host
Configuration Protocol, dynamic host configuration protocol) request when, responded.Wherein, if it is ARP request, nothing
Line router 200 can for example send corresponding MAC Address.If it is DHCP request, then wireless router 200 can be without
Response, neglects the request.
Above-mentioned data are placed in caching by step S214.
Multicast message and broadcasting packet are all the data unrelated with WIFI module 120.Therefore, in the present embodiment, no route
The data filtering unrelated with WIFI module 120 is fallen by device 200, to avoid some unrelated data being sent to WIFI module
120, it may make WIFI module 120 in a power-save mode without frequently receiving data, to further decrease power consumption.
Further, some broadcast of wireless router 200, the application service of multicast, such as UPNP can also be closed
(Universal Plug and Play), IGMP (Internet Group Management Protocol), thus further
Simplify the application of router.
