The information processing method, system, and apparatus are provided. Information processing method, a user device (user equipment: UE) of the source serving cell is located in an evolved NodeB (eNodeB) in by transmitting the information to receive that step a, wherein the information source serving cell is located in eNodeB the UE process the data transmitted by the after processing status information and the data information obtained, or a source serving cell the data information in the at least two user plane protocol stack of the eNodeB, which is located, or a source serving cell, packet data convergence of eNodeB, which is located protocol (Packet data Convergence protocol: PDCP) except for containing the data information in the user plane protocol stack, receiving the information; And corresponding to, a step of, depending on the processing condition information, the data information, or the data information in the at least two user plane protocol stack, or data information in the user plane protocol stack, except for the PDCP, transmitting and receiving a UE and the data do. The information processing system includes an evolved Node in the source Non-located serving cell (eNodeB) and the target serving cell evolved Node B, which is located (eNodeB). eNodeB includes source information receiving unit and the information transmitting unit. The process for the information sent by the source eNodeB are performed.
