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.
