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, 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.
