When the data of the mac frame format forwarded by the client interface from the wireless router of network side When message, the MAC Address that address is wireless router of sending in the data message is obtained, determines the data message Type is Second Type；Wherein, the data message of the Second Type be sent by the second wireless site and passed through it is described wireless Router is forwarded to the client interface.

It should be noted that the client interface and AP interface of terminal device are located in the same bridge, terminal at this time It has been not necessarily to carry out the setting of DHCP Server and Soft AP gateway in equipment, to also avoid gateway that may be present Conflict.Terminal device and wireless router, which are established, to be connected to the network, and the first wireless site and the second wireless site are set by terminal Standby bridge mode is able to carry out data interaction communication.Wherein, data message transmitted by the first wireless site or by wireless The data message that router side is forwarded is the data message of mac frame format, it is the data packet frame propagated in air, can With referred to as Air Packet Frame；The data message of mac frame format can be converted to ethernet frame format in bridge Data message, it is the data packet frame propagated in bridge, is referred to as Bridge Packet Frame at this time；Then should Data message will continue to send with the data message of mac frame format.

It should also be noted that, the transmission of data message includes two kinds of situations: one is data messages by wireless site STA Side is sent to the wireless router AP (i.e. To AP) of network side by client interface, another is data message by network The wireless router AP of side is sent to the side wireless site STA (i.e. From AP) by client interface.In this way, for different The transmission address of situation, data message is also different；For example client interface is passed through to wireless routing from the first wireless site The data message that device is forwarded, the data message send the MAC Address that address is the first wireless site, the class of the data message Type is known as the first kind；Such as the data message forwarded by client interface from wireless router, the data Message sends the MAC Address that address is wireless router, and the type of the data message is known as Second Type.

Illustratively, it by taking network topology structure shown in Fig. 3 as an example, according to the regulation of 802.11 agreement of IEEE, obtains The data message of mac frame format can use Data [To DS, From DS, Address1, Address2, Address3, Source IP, Dest IP] it indicates, and the data message that ethernet frame format is obtained in Bridge can use Data [Dest Address, Source Address, Source IP, Dest IP] it indicates.In the interactive process of data message, it is assumed that first Wireless site is STA1, and the second wireless site is STA2, send STA2 for data message by STA1, at this time the data message Type is the first kind, and STA0 will receive the data message of mac frame format transmitted by STA1 by AP interface, use Data [1,0, AP-BSSID, STA1-MAC, STA2-MAC, STA1-IP, STA2-IP] is indicated, then by Client interface by the MAC The data message forwarding of frame format is to the side Root AP；Wherein, the driving of Client interface side can will also receive in bridge The data message of mac frame format is converted to the data message of ethernet frame format, with Data [STA2-MAC, STA1-MAC, STA1-IP, STA2-IP] it indicates；Similarly, it is assumed that the first wireless site is STA1, and the second wireless site is STA2, will by STA2 Data message is sent to STA1, and the type of the data message is Second Type at this time, and STA0 will be received by client interface The data message of mac frame format transmitted by STA2, the data message are to be forwarded by STA2 by Root AP, with Data [0, 1, Client-MAC, Root AP-MAC, STA2-MAC, STA2-IP, STA1-IP] it indicates；Wherein, the Client in bridge Interface side drives the data message that the data message of the mac frame format received can be also converted to Ethernet protocol format, uses Data [Client-MAC, STA2-MAC, STA2-IP, STA1-IP] is indicated.

It is to be appreciated that be directed to the first kind data message, if send address Address2 using source address (such as STA1-MAC shown in Fig. 3), then the side Root AP will can not identify and abandon the data message of the mac frame format, this Shi Bixu unsteady state operation Address2 is Client-MAC, just can ensure that the side Root AP normally receives the data message； Similarly, for the data message of Second Type, in bridge, the data message of mac frame format is converted into ethernet frame lattice The data message of formula, if destination address Dest Address, which is used, receives address (than Client-MAC as shown in Figure 3), So bridge meeting can not be normally by the data message forwarding of the ethernet frame format to AP interface, at this time must unsteady state operation Dest Address is STA1-MAC, i.e., the reception address Address1 in the data message of mac frame format is converted to STA1- MAC can ensure that STA1 normally receives the data message in this way.That is, in order to guarantee data message just Often interaction needs to increase ATE mechanism in the client interface side driving of terminal device to carry out address conversion and address conversion The updating maintenance of table, to solve the consumption of cpu resource brought by existing scheme and gateway collision problem.

In some embodiments, after the type of the determination data message, the method also includes:

By the address translation engine ATE in the client interface, stored address translation table is obtained；Wherein, institute Address translation table is stated to be used for the transmission address in the data message and/or receive address progress address conversion processing.

Further, in some embodiments, described to the number when the type of the data message is the first kind Address conversion is carried out according to the transmission address in message, comprising:

The data message from the first wireless site into the transmission process of the second wireless site, according to the ground got Transmission address in the data message is converted to the client by the MAC Address of the first wireless site and connect by location conversion table The MAC Address of mouth, obtains new data message.

Further, in some embodiments, described to the number when the type of the data message is Second Type Address conversion is carried out according to the reception address in message, comprising:

The data message from the second wireless site into the transmission process of the first wireless site, according to the ground got Reception address in the data message is converted to first nothing by the MAC Address of the client interface by location conversion table The MAC Address of line website obtains new data message.

It should be noted that increasing ATE mechanism in the client interface side driving of terminal device；In this way, working as data message Type be the first kind when, i.e., the datagram of the mac frame format forwarded by the client interface to wireless router side Text can be turned by carrying out address to the transmission address Address2 in data message from the address translation table got in ATE It changes, is converted into Client-MAC, obtain new data message；When the type of data message is Second Type, that is, pass through The data message for the mac frame format that the Client interface is forwarded from wireless router side, can be by from ATE The address translation table got carries out address conversion to the reception address Address1 in data message, is converted into really The MAC Address (such as MAC Address of the first wireless site) of STA then will obtain new data message and pass through the AP interface It is forwarded to the first wireless site.

Illustratively, still by taking network topology structure shown in Fig. 3 as an example, it is assumed that data message is sent STA2 by STA1, So the type of the data message is the first kind, and STA0 will receive mac frame format transmitted by STA1 by AP interface Data message is indicated with Data [1,0, AP-BSSID, STA1-MAC, STA2-MAC, STA1-IP, STA2-IP]；In bridge In, which can then be converted to ethernet frame format, with Data [STA2-MAC, STA1-MAC, STA1-IP, STA2-IP] It indicates；Then the side Root AP is sent according to mac frame format by the data message by Client interface again, wherein if sent Address Address2 uses source address (such as STA1-MAC in Fig. 3), then the obtained mac frame format in the side Root AP Data message is Data [1,0, Root AP-BSSID, STA1-MAC, STA2-MAC, STA1-IP, STA2-IP], due to sending Address Address2 is STA1-MAC, it will causes the side Root AP that can not identify the data message of the mac frame format and directly lose It abandons, it is Client-MAC, the i.e. side Root AP institute that address Address2 unsteady state operation will be sent by address translation table at this time by, which needing, The data message of obtained mac frame format is Data [1,0, Root AP-BSSID, Client-MAC, STA2-MAC, STA1- IP, STA2-IP], it just may insure that the side Root AP can normally receive the data message in this way.Similarly, it is assumed that STA2 is by data Message is sent to STA1, then the type of the data message is Second Type, STA0 will receive Root by Client interface The data message for the mac frame format that the side AP is forwarded, with Data [0,1, Client-MAC, Root AP-BSSID, STA2-MAC, STA2-IP, STA1-IP] it indicates；In bridge, which can then be converted to ethernet frame format, use Data [Client-MAC, STA2-MAC, STA2-IP, STA1-IP] is indicated；Then again by Client interface by the data message according to Ethernet frame format is sent to AP interface side, is forwarded to STA1 by AP interface；Wherein, in bridge, if destination address Dest Address is using address (such as Client-MAC in Fig. 3) is received, then the obtained ether of Client interface side The data message of net frame format will will lead to bridge and it normally can not be forwarded to AP interface and directly be abandoned, and need to lead at this time Crossing address translation table and receiving address Address1 unsteady state operation is STA1-MAC, i.e., is forwarded by AP interface to the side STA1 The data message of mac frame format is Data [0,1, STA1-MAC, AP-BSSID, STA2-MAC, STA2-IP, STA1-IP], this Sample just may insure that the side STA1 can normally receive the data message.
