<p>A method for protecting data in the unstructured supplementary service data (USSD) is provided, and the method includes: a network entity sends and buffers service data based on a service session, and monitors whether the network is abnormal at the same time; when the network is abnormal, the network entity re-monitors the network state in a predetermined period. With the solution of the present invention, when the network is abnormal, the network entity will not discard the current service data, but store the service data according to the network state and monitor the network state in real time; when the network recovers, the network entity will continue transmitting the stored service data to a next-level network entity; if the network can not recover in a short time, the network entity will store the current service session state in the buffer. Thus, the trouble for users caused by the interaction between service sessions is avoided.</p> |
