A method for handover between distributed access points, comprising: receiving, by a first distributed access point AP, a handover request sent by a central AP, wherein the handover request comprises an address of a wireless terminal and an identifier of a second distributed AP; and sending, by the first distributed AP, a context handover request to the second distributed AP after receiving the handover request, wherein the context handover request comprises an unsent frame of the wireless terminal, the unsent frame is a frame that has not been sent to the wireless terminal among frames of the wireless terminal that are stored in the first distributed AP, and the context handover request is used to instruct the second distributed AP to send the unsent frame to the wireless terminal; wherein the method further comprises: receiving, by the first distributed AP, a first Ethernet frame sent by the central AP, wherein a destination address of the first Ethernet frame is the address of the wireless terminal; saving, by the first distributed AP, the first Ethernet frame, wherein the frames of the wireless terminal that are stored in the first distributed AP comprise the first Ethernet frame; or converting, by the first distributed AP, the first Ethernet frame into a first radio frame, and saving the first radio frame, wherein the frames of the wireless terminal that are stored in the first distributed AP comprise the first radio frame; and sending, by the first distributed AP, a first instruction to the central AP when a storage volume of the first distributed AP is greater than a threshold, wherein the first instruction comprises the address of the wireless terminal, and the first instruction is used to instruct the central AP to decrease a rate of sending an Ethernet frame of the wireless terminal. receiving, by a first distributed access point AP, a handover request sent by a central AP, wherein the handover request comprises an address of a wireless terminal and an identifier of a second distributed AP; and sending, by the first distributed AP, a context handover request to the second distributed AP after receiving the handover request, wherein the context handover request comprises an unsent frame of the wireless terminal, the unsent frame is a frame that has not been sent to the wireless terminal among frames of the wireless terminal that are stored in the first distributed AP, and the context handover request is used to instruct the second distributed AP to send the unsent frame to the wireless terminal; wherein the method further comprises: receiving, by the first distributed AP, a first Ethernet frame sent by the central AP, wherein a destination address of the first Ethernet frame is the address of the wireless terminal; saving, by the first distributed AP, the first Ethernet frame, wherein the frames of the wireless terminal that are stored in the first distributed AP comprise the first Ethernet frame; or converting, by the first distributed AP, the first Ethernet frame into a first radio frame, and saving the first radio frame, wherein the frames of the wireless terminal that are stored in the first distributed AP comprise the first radio frame; and sending, by the first distributed AP, a first instruction to the central AP when a storage volume of the first distributed AP is greater than a threshold, wherein the first instruction comprises the address of the wireless terminal, and the first instruction is used to instruct the central AP to decrease a rate of sending an Ethernet frame of the wireless terminal. receiving, by the first distributed AP, a first Ethernet frame sent by the central AP, wherein a destination address of the first Ethernet frame is the address of the wireless terminal; saving, by the first distributed AP, the first Ethernet frame, wherein the frames of the wireless terminal that are stored in the first distributed AP comprise the first Ethernet frame; or converting, by the first distributed AP, the first Ethernet frame into a first radio frame, and saving the first radio frame, wherein the frames of the wireless terminal that are stored in the first distributed AP comprise the first radio frame; and sending, by the first distributed AP, a first instruction to the central AP when a storage volume of the first distributed AP is greater than a threshold, wherein the first instruction comprises the address of the wireless terminal, and the first instruction is used to instruct the central AP to decrease a rate of sending an Ethernet frame of the wireless terminal.
