Abstract

A data transmission method, multi-medium access point and multi-medium client are disclosed. The method includes: a multi-medium access point (AP) acquiring a current wireless local area network (WLAN) operating mode of an opposite end multi-medium client (Client) from the opposite end multi-medium Client; and the multi-medium AP comparing an address of a target device to which a data packet to be sent is sent with an address of the opposite end multi-medium Client, if they are different, judging whether both a current WLAN operating mode of the multi-medium AP and the current WLAN operating mode of the opposite end multi-medium Client are three-address modes or not, and if yes, determining that the data packet to be sent is prohibited from being sent through a wireless fidelity (WiFi) interface of the multi-medium AP.

Claims

1. A data transmission method, comprising:

a multi-medium access point (AP) acquiring a current wireless local area network (WLAN) operating mode of an opposite end multi-medium client (Client) from the opposite end multi-medium Client; and

the multi-medium AP comparing an address of a target device to which a data packet to be sent is sent with an address of the opposite end multi-medium Client, if the address of the target device to which the data packet to be sent is sent and the address of the opposite end multi-medium Client are different, judging whether both a current WLAN operating mode of the multi-medium AP and the current WLAN operating mode of the opposite end multi-medium Client are three-address modes or not, and if yes, determining that the data packet to be sent is prohibited from being sent through a wireless fidelity (WiFi) interface of the multi-medium AP.

2. The method according to claim 1, further comprising:

after determining that the data packet to be sent is prohibited from being sent through the WiFi interface of the multi-medium AP, the multi-medium AP sending the data packet to be sent through interfaces except the WiFi interface on the multi-medium AP.

3. A multi-medium access point, comprising:

an abstraction layer entity, wherein;

the abstraction layer entity is configured to;

acquire a current wireless local area network (WLAN) operating mode of an opposite end multi-medium client (Client) from the opposite end multi-medium Client, compare an address of a target device to which a data packet to be sent is sent with an address of the opposite end multi-medium Client, if the address of the target device to which the data packet to be sent is sent and the address of the opposite end multi-medium Client are different, judge whether both a current WLAN operating mode of the multi-medium access point (AP) and the current WLAN operating mode of the opposite end multi-medium Client are three-address modes or not, and if yes, determine that the data packet to be sent is prohibited from being sent through a wireless fidelity (WiFi) interface of the multi-medium AP.

4. The multi-medium access point according to claim 3, wherein,

the abstraction layer entity is further configured to:

after determining that the data packet to be sent is prohibited from being sent through the WiFi interface of the multi-medium AP, send the data packet to be sent through interfaces except the WiFi interface on the multi-medium AP.

5. The multi-medium access point according to claim 4, further comprising:

a wireless local area network media access control (WLAN MAC) entity or an upper layer entity, wherein;

the abstraction layer entity is further configured to;

query the current WLAN operating mode of the multi-medium AP from the WLAN MAC entity or the upper layer entity, and notify the opposite end multi-medium Client of the current WLAN operating mode of the multi-medium AP acquired by querying;

or after the current WLAN operating mode of the multi-medium AP is changed, acquire the current WLAN operating mode of the multi-medium AP according to a notification of the WLAN MAC entity or the upper layer entity, and notify the opposite end multi-medium Client of the acquired current WLAN operating mode of the multi-medium AP.

6. A data transmission method, comprising:

a multi-medium client (Client) acquiring a current wireless local area network (WLAN) operating mode of an opposite end multi-medium access point (AP) from the opposite end multi-medium AP; and

the multi-medium Client comparing an address of a device in which a data packet to be sent is initially sent with an address of the multi-medium Client, if the address of the device in which the data packet to be sent is initially sent and the address of the multi-medium Client are different, judging whether both a current WLAN operating mode of the multi-medium Client and the current WLAN operating mode of the opposite end multi-medium AP are three-address modes or not, and if yes, determining that the data packet to be sent is prohibited from being sent through a wireless fidelity (WiFi) interface of the multi-medium Client.

7. The method according to claim 6, further comprising:

after determining that the data packet to be sent is prohibited from being sent through the WiFi interface of the multi-medium Client, the multi-medium Client sending the data packet to be sent through interfaces except the WiFi interface on the multi-medium Client.

8. A multi-medium client, comprising:

an abstraction layer entity, wherein;

the abstraction layer entity is configured to;

acquire a current wireless local area network (WLAN) operating mode of an opposite end multi-medium access point (AP) from the opposite end multi-medium AP, compare an address of a device in which a data packet to be sent is initially sent with an address of the multi-medium client (Client), if the address of the device in which the data packet to be sent is initially sent and the address of the multi-medium Client are different, judge whether both a current WLAN operating mode of the multi-medium Client and the current WLAN operating mode of the opposite end multi-medium AP are three-address modes or not, and if yes, determine that the data packet to be sent is prohibited from being sent through a wireless fidelity (WiFi) interface of the multi-medium Client.

9. The multi-medium client according to claim 8, wherein:

the abstraction layer entity is further configured to;

after determining that the data packet to be sent is prohibited from being sent through the WiFi interface of the multi-medium Client, send the data packet to be sent through interfaces except the WiFi interface on the multi-medium Client.

10. The multi-medium client according to claim 9, further comprising:

a wireless local area network media access control (WLAN MAC) entity or an upper layer entity, wherein;

the abstraction layer entity is further configured to;

query the current WLAN operating mode of the multi-medium Client from the WLAN MAC entity or the upper layer entity, and notify the opposite end multi-medium AP of the current WLAN operating mode of the multi-medium Client acquired by querying;

or after the current WLAN operating mode of the multi-medium Client is changed, acquire the current WLAN operating mode of the multi-medium Client according to a notification of the WLAN MAC entity or the upper layer entity, and notify the opposite end multi-medium AP of the acquired current WLAN operating mode of the multi-medium Client.
