An information processing method and system, and a mobility management network element are provided by the embodiments of the present invention. Wherein, the information processing method includes: receiving a message that includes data information of a user equipment UE; determining that the UE is a UE of low data usage; and sending the received data information of the UE to a machine type control server. By using the method, when the UE of low data usage implements a service, the mobility management network element sends the data, which is sent by the UE, to the machine type control server so that the machine type control server processes the data of the UE. Further, when the UE of low data usage sends data information to the mobility management network element, no bearer is activated, and the network side does not need to allocate bearer resources for data transmission of the UE. Therefore, the network load is reduced.
