Data processing method, apparatus, and mobile terminal are provided. A requesting end adds a reserved field to data to be stored to obtain target data, and sends the target data to a storing end. The storing end allocates a memory to cache the target data, generates data metadata of the data to be stored in the target data, and writes the data metadata to a memory location corresponding to the reserved field in the memory. The embodiments of the present disclosure realize zero copying, ensure the efficiency of data storage, and improve the system performance.
