Title: METHOD, DEVICE, AND SYSTEM FOR IDENTIFYING INVALID BEARER CONTEXT
Abstract:
Embodiments of the present invention relate to the field of communications and provide a method, device, and system for identifying an invalid bearer context. The method for identifying an invalid bearer context comprises: an MME receives, from an SGW-C, a notification message carrying anomaly indicating information; and the MME determines an invalid bearer context according to the anomaly indicating information. By receiving, from the SGW-C, a notification message carrying anomaly indicating information, and determining an invalid bearer context according to the anomaly indicating information, the MME can learn about an abnormal bearer in a timely manner to avoid a data transmission failure caused by invalid bearer information, thereby improving user experience.
