Abstract

The present invention discloses a service processing method and apparatus, which belong to the field of Internet technologies. After the AP and an STA first perform MAC address change notification and then establish a first MAC connection, the AP sends service data of the STA to the STA through the first MAC connection by using a resource related to a second MAC connection. Therefore, in a MAC address change process, there is no need to re-establish a resource at an upper layer of a MAC layer, and only a change in invoking a MAC layer resource is required at a layer at which the MAC layer resource is used. Time and a resource for processing a service can be reduced without affecting service continuity and stability of the upper layer. Therefore, the service is processed in a timely manner and service processing efficiency is improved.

Claims

1. A service processing method, wherein the method comprises:

receiving, by an access point, a connection request that is sent by a station (STA) by using a first media access control (MAC) address; and

establishing a first MAC connection to the STA according to the first MAC address, wherein the first MAC address is the MAC address of the STA after the STA changes its MAC address from a second MAC address to the first MAC address;

receiving, by the access point, a MAC address change message that is sent by the STA in an encryption mode, wherein the MAC address change message carries the second MAC address;

determining, according to the MAC address change message, that the STA has changed its MAC address; and

determining that a second MAC connection to the STA has been established by using the second MAC address; and

sending, by the access point, service data of the STA to the STA through the first MAC connection by using a resource related to the second MAC connection.

2. The method according to claim 1, wherein after receiving the MAC address change message, no new Internet Protocol (IP) address is assigned to the STA.

3. The method according to claim 1, wherein sending the service data of the STA to the STA through the first MAC connection by using the resource related to the second MAC connection further comprises:

sending the service data of the STA, which was previously sent to the STA through the second MAC connection, to the STA through the first MAC connection by using the resource related to the second MAC connection.

4. A service processing Method, wherein the method comprises:

performing, by an access point, media access control (MAC) address change notification with a station (STA) in an encryption mode, wherein the access point and the STA have established a second MAC connection, the second MAC connection is established according to a second MAC address used by the STA, and the second MAC address is the MAC address of file STA before the STA changes it'"'"'s MAC address from the second MAC address to a first MAC address;

receiving, by the access point, a connection request that is sent by the STA by using the first MAC address;

establishing, by the access point, a first MAC connection to the STA according to the first MAC address; and

sending, by the access point, service data of the STA to the STA through the first MAC connection by using a resource related to the second MAC connection.

5. The method according to claim 4, wherein the sending the service data of the STA to the STA through the first MAC connection by using a resource related to the second MAC connection further comprises:

sending the service data of the STA, which was sent to the STA through the second MAC connection, to the STA through the first MAC connection by using the resource related to the second MAC connection.

6. The method according to claim 4, wherein performing, the MAC address change notification in the encryption mode further comprises:

sending, by the to the STA in an encryption mode, a notification message for instructing the STA to change its MAC address.

7. The method according to claim 4, wherein performing the MAC address change notification in the encryption mode further comprises:

receiving, by the access point, a notification message from the STA for notifying the access point that the STA intends to change its MAC address, and determining, according to the notification message, that the STA intends to change its MAC address.

8. The method according to claim 4, further wherein after the connection request that is sent by the STA by using the first MAC address is received, no new Internet Protocol (IP) address is assigned to the STA.

9. A device, wherein the device comprises:

a processor, configured to perform media access control (MAC) address change notification with a station (STA) in art encryption mode, wherein the device and the STA have established a second MAC connection, the second MAC connection is established according to a second MAC address used by the STA, and the second MAC address is the MAC address of the STA before the STA changes its MAC address from the second MAC address to a first MAC address; and

a receiver, configured to receive a connection request that is sent by the STA by using the first MAC address;

wherein the processor is further configured to establish a first MAC connection to the STA according to the first MAC address;

wherein the device further comprises a transmitter, configured to send service data of the STA to the STA through the first MAC connection by using a resource related to the second MAC connection.

10. The device according to claim 9, wherein sending the service data of the STA to the STA through the first MAC connection by using a resource related to the second MAC connection further comprises:

sending the service data of the STA, which was previously sent to the STA through the second MAC connection, to the STA through the first MAC connection by using the resource related to the second MAC connection.

11. The device according to claim 9, wherein performing the MAC address change notification in the encryption mode further comprises:

sending, to the STA in an encryption mode, a notification message for instructing the STA to change its MAC address.

12. The device according to claim 9, wherein performing, the MAC address change notification in the encryption mode further comprises:

receiving a notification message for notifying the device that the STA intends to change its MAC address; and

determining, according to the notification message, that the STA intends to change its MAC address.

13. The device according to claim 9, wherein the processor is further configured not to assign a new Internet Protocol (IP) address to the STA after the receiver receives the connection request that is sent by the STA by using the first MAC address.
