Embodiments of the present invention disclose a mobility management method, device and system, which relate to the field of communications and improve handover performance in the mobility management process. The specific solution is: when the UE moves from the cell covered by the first access network node to the cell covered by the second access network node, the second access network node receives the handover request sent by the first access network node through the X2 connection; The second access network node sends a handover request confirmation to the first access network node through the X2 connection, so that the first access network node and the second access network node execute the handover execution process; the second access network node determines that it needs to communicate with the An MME establishes a dynamic S1 connection; a second access network node establishes a dynamic S1 connection with the first MME; and the second access network node initiates a path switching process to the first MME through the dynamic S1 connection. The invention is used in the process of mobility management.
