FIELD: wireless communication equipment.
SUBSTANCE: invention relates to communication. To achieve technical result in user data processing device interface control unit receives user data; at least two service units process user data, where at least two service units include a session unit and at least one of a bearer channel unit, a service flow unit and a content unit; interface control unit determines a session unit configured to process user data and sends received user data to a specific session unit; and the session unit determines another service unit configured to process user data. Upon receiving user data, GW-U determines a service unit configured to process user data and processes user data through a service unit defined by GW-U.
EFFECT: user GW-U plane can flexibly process user data.
