A method for managing network topology structure of a Machine to Machine, M2M, network, comprising: obtaining wireless link information of the M2M network by a control station of the M2M network; completing, according to the obtained wireless link information, establishment and/or adjustment of network topology structure of the M2M network by the control station; wherein the process of obtaining wireless link information of the M2M network comprises: after accessing the network, a sending node in the M2M network sends a detection signal to each receiving node; after receiving the detection signal, each receiving node feeds back signal receiving strength of the detection signal which serves as wireless link information to each sending node; each sending node performs operation on the signal receiving strength fed back by each receiving node, and sends an operation result to the control station; wherein the process that the control station completes establishment and/or adjustment of network topology structure of the M2M network comprises: the control station selects a node with the most balanced signal receiving strength as the sub-control station, or selects a node with the maximum signal receiving strength as the sub-control station, according to the operation result sent by each sending node. obtaining wireless link information of the M2M network by a control station of the M2M network; completing, according to the obtained wireless link information, establishment and/or adjustment of network topology structure of the M2M network by the control station; wherein the process of obtaining wireless link information of the M2M network comprises: after accessing the network, a sending node in the M2M network sends a detection signal to each receiving node; after receiving the detection signal, each receiving node feeds back signal receiving strength of the detection signal which serves as wireless link information to each sending node; each sending node performs operation on the signal receiving strength fed back by each receiving node, and sends an operation result to the control station; wherein the process that the control station completes establishment and/or adjustment of network topology structure of the M2M network comprises: the control station selects a node with the most balanced signal receiving strength as the sub-control station, or selects a node with the maximum signal receiving strength as the sub-control station, according to the operation result sent by each sending node. after accessing the network, a sending node in the M2M network sends a detection signal to each receiving node; after receiving the detection signal, each receiving node feeds back signal receiving strength of the detection signal which serves as wireless link information to each sending node; each sending node performs operation on the signal receiving strength fed back by each receiving node, and sends an operation result to the control station; wherein the process that the control station completes establishment and/or adjustment of network topology structure of the M2M network comprises: the control station selects a node with the most balanced signal receiving strength as the sub-control station, or selects a node with the maximum signal receiving strength as the sub-control station, according to the operation result sent by each sending node. <EOS>
