Abstract
The invention discloses a method and a device for transmitting a multicast/broadcast message through a wireless access point. When receiving a multicast/broadcast message, the wireless access point detects the working state of a linked workstation. The method further comprises the following steps: when the workstation which is associated to the wireless access point comprises a workstation of the energy-saving state and a workstation of the normal state, the wireless access point copies the multicast/broadcast message and transmits the multicast/broadcast message to the associated workstation; and the wireless access point awakens the workstation staying at the energy-saving state so as to transmit the copied multicast/broadcast massage to the workstation which is awakened. Through the method, the multicast/broadcast message is rapidly transmitted from the wireless access point to the associated workstation.
Description
Technical field
The present invention relates to the communications field, relate in particular to the method and apparatus that a kind of WAP (wireless access point) sends multicast.
Background technology
In WLAN (Wireless Local Access Network, WLAN (wireless local area network)) network,, designed the Station sleep function in order to save the electric quantity consumption of Station (work station).When having data message mutual between Station and the AP (Access Point, access point), Station is in waking state, i.e. normal operating conditions; When not having data message mutual between Station and the AP, Station is in sleep (Sleep) state, i.e. electricity-saving state.
When Station was in the Sleep state, Station sent the Null message by periodically waking up to AP and keeps and being connected of AP.If AP receives the Null message that Station sends in Preset Time, then AP keeps the incidence relation with Station; If AP does not receive the Null message that Station sends in Preset Time, then AP judges that Station rolls off the production line.After Station periodically woke up, Station can also receive the control message that AP sends, for example beacon (beacon) message.In the prior art, when AP need be when Sleep Station sends multicast or unicast message, AP at first wakes Sleep Station up by the beacon message.
Concrete, when AP need be when Station sends unicast message, AP detects the operating state of Station.As shown in Figure 2, when Station was in normal condition, AP directly sent unicast message to Station; When Station was in the Sleep state, AP is this unicast message of buffer memory at first, sent the unicast message of buffer memory after waking SleepStation up again to this Sleep Station.
When AP need be when Station sends multicast, AP at first detects the operating state of related Station.When the Station of AP association all is in normal condition, as shown in Figure 1, AP directly sends multicast to the Station of association, the Station that receives this multicast judges whether to belong to the multicast of self required reception according to the destination address of message, and according to judged result multicast is handled accordingly.When comprising the Station that is in the Sleep state among the Station of AP association, AP needs at first buffer memory multicast, AP wakes Sleep Station up by broadcasting beacon message then, carries the identification information of Sleep Station in this beacon message.The Station that receives the beacon message obtains the identification information in the beacon message, if the Station of this identification information sign be self, then this Station switches to normal condition with oneself state by Sleep, and to AP transmission response message.After the Sleep of association Station all was waken up, AP sent the multicast of buffer memory again to each Station.
But, owing to can comprise the Station that constantly is in power save mode individually among a plurality of Station of AP association, the very fast power save mode that enters again after this Station is waken up by power save mode, thereby cause AP when a plurality of Station send multicast, can need repetition buffer memory multicast, wake the process of Sleep Station up, cause great network delay, influence the work of other normal conditions Station.

Embodiment
Core concept of the present invention is: AP directly sends the multicast that receives to the Station of association, AP also distinguishes the Station that is in power save mode and normal condition, for Sleep Station, AP duplicated multicast/broadcasting packet also sends to Sleep Station with the clean culture form.
The invention provides the method that a kind of WAP (wireless access point) sends multicast, when receiving multicast, described WAP (wireless access point) detects the operating state of hanging work station down, and as shown in Figure 3, described method further comprises:
Introduce the method that WAP (wireless access point) provided by the invention sends multicast in detail below in conjunction with concrete application scenarios.
As shown in Figure 4, related many user terminals of AP one side in this application scenarios, opposite side connects network equipment, and the method for the WAP (wireless access point) transmission multicast that this application scenarios provides may further comprise the steps as shown in Figure 5:
Concrete, the maximum of the number of Sleep Station is set among the AP, this maximum can represent that its value is concrete to be obtained by following formula with S:
S＝X·R
u/R
m
Wherein, R
mBe the multicast transmission rate of WAP (wireless access point), R
uBe the clean culture transmission rate of WAP (wireless access point), X is a threshold value.
Threshold value X can be provided with according to actual needs flexibly, and preferred, X is 1.At this moment, all send to Station by the clean culture form multicast time and be not more than the time that sends a multicast to Station.
Concrete, AP sends the beacon message to Sleep Station and wakes Sleep Station up.AP uses the source MAC of the Station that is waken up to encapsulate the multicast of buffer memory again.The heading of beacon message is as shown in table 1:
Table 1
Octets：2 2 6 6 6 2 6 2 0-23424 4
| Frame Control | Duratlonl ID | Address1 | Address2 | Address3 | Sequence Control | Address4 | QoS Control | Frame Body | FCS |
In the table 1, in the heading of wireless 802.11 messages, the destination address of message is Address1.AP is replaced by the source MAC of each SleepStation respectively with the multicast/broadcast address of the Address1 in the multicast of buffer memory, changes a multicast into a plurality of unicast messages of going to different SleepStation.AP abandons the multicast of buffer memory then with these unicast message difference buffer memorys of going to different station, discharges internal memory.
Should be with in the scene, whether AP needs to judge the number of Sleep Station and the relation of preset maximum value, determine according to actual needs, for example AP also can not go to judge the number of Sleep Station, and when in the Station of association, comprising Sleep Station and Active Station, promptly send multicast, send multicast with the clean culture form to Sleep Station then.
By adopting method provided by the invention, when the work station of work station that comprises power save mode in the work station of WAP (wireless access point) association and normal condition, WAP (wireless access point) directly sends the multicast that receives to the work station of association, and duplicate this multicast, then after the work station of power save mode is waken up, send to the work station that is waken up with the unicast message form duplicating the multicast that obtains, thereby avoided the individual work station constantly to be in power save mode and the network delay that causes to other work stations of hanging under the WAP (wireless access point).
The invention provides a kind of WAP (wireless access point), when receiving multicast, described WAP (wireless access point) detects the operating state of hanging work station down, and as shown in Figure 6, described WAP (wireless access point) comprises:
Copied cells 10 when being used for work station when described WAP (wireless access point) association and comprising the work station of the work station of power save mode and normal condition, duplicates described multicast;
