Abstract: A data processing method, a device, and a system for a storage unit in order to avoid performing repeated data read operations on the storage unit where the method includes recording, by a first server for at least one storage unit used to store data, information about a storage unit in which a repairable fault occurs but repairing fails, querying, by the first server each time a request for reading data is received, whether the storage unit corresponding to the recorded information about the storage unit stores a part or all of the data, and when the storage unit corresponding to the recorded information stores the data, returning, to a requesting party that sends the request, a message indicating that reading the data fails, or otherwise, reading the data from a storage unit that stores the data, and feeding back the data to the requesting party that sends the request.

Abstract: The present disclosure relates to a user data processing apparatus and method, and a system. In the user data processing apparatus disclosure, an interface management unit receives user data; at least two service units process the user data, where the at least two service units include a session unit and at least one of a bearer unit, a service flow unit, or a content unit; the interface management unit determines the session unit configured to process the user data, and sends the received user data to the determined session unit; and the session unit determines another service unit configured to process the user data. After receiving the user data, the GW-U determines the service unit configured to process the user data, and processes the user data by using the service unit determined by the GW-U. This improves processing flexibility of the GW-U.
