A method for wirelessly accessing a service, the method being characterized by comprising: detecting, by a wireless access device, whether quality of a first wireless access link satisfies a communication quality requirement of a single mobile terminal, wherein the first wireless access link is a wireless access link between the wireless access device at a current location and the mobile terminal; starting, by the wireless access device, moving when the wireless access device determines that the quality of the first wireless access link does not satisfy the communication quality requirement of the single mobile terminal, wherein the starting moving comprises: acquiring, by the wireless access device according to a parameter of the first wireless access link, a direction of the single mobile terminal relative to the wireless access device; and determining, by the wireless access device, that the direction of the single mobile terminal relative to the wireless access device is the first target direction, and wherein the direction is determined according to a direction in location information of the single mobile terminal relative to the wireless access device, or determined according to a connection line between coordinates of the single mobile terminal and coordinates of the wireless access device; detecting, by the wireless access device in a moving process of the wireless access device, whether quality of a second wireless access link satisfies the communication quality requirement of the single mobile terminal, wherein the second wireless access link is a wireless access link between the wireless access device at a location after the movement and the mobile terminal; and stopping, by the wireless access device, moving when the quality of the second wireless access link satisfies the communication quality requirement of the single mobile terminal; or continuing, by the wireless access device, moving when the quality of the second wireless access link does not satisfy the communication quality requirement of the single mobile terminal. detecting, by a wireless access device, whether quality of a first wireless access link satisfies a communication quality requirement of a single mobile terminal, wherein the first wireless access link is a wireless access link between the wireless access device at a current location and the mobile terminal; starting, by the wireless access device, moving when the wireless access device determines that the quality of the first wireless access link does not satisfy the communication quality requirement of the single mobile terminal, wherein the starting moving comprises: acquiring, by the wireless access device according to a parameter of the first wireless access link, a direction of the single mobile terminal relative to the wireless access device; and determining, by the wireless access device, that the direction of the single mobile terminal relative to the wireless access device is the first target direction, and wherein the direction is determined according to a direction in location information of the single mobile terminal relative to the wireless access device, or determined according to a connection line between coordinates of the single mobile terminal and coordinates of the wireless access device; detecting, by the wireless access device in a moving process of the wireless access device, whether quality of a second wireless access link satisfies the communication quality requirement of the single mobile terminal, wherein the second wireless access link is a wireless access link between the wireless access device at a location after the movement and the mobile terminal; and stopping, by the wireless access device, moving when the quality of the second wireless access link satisfies the communication quality requirement of the single mobile terminal; or continuing, by the wireless access device, moving when the quality of the second wireless access link does not satisfy the communication quality requirement of the single mobile terminal.
