METHOD AND DEVICE FOR HANDLING CONGESTION IN MACHINE TYPE COMMUNICATIONS

摘要

Disclosed are a method and a device for handling congestion in machine type communications (MTC). The method comprises: upon receiving a tracking area update (TAU) request message initiated by a user equipment (UE), a mobility management entity (MME) confirming a subscribed access point name (APN) of the UE; the MME confirming among the subscribed APNs an APN being congested; the MME indicating in a TAU accept message being returned to the UE the congested APN among the subscribed APNs, and indicating a session management back-off timer being allocated for the congested APN. The present invention provides an improvement over the illogicality in the prior art, reduces signaling resource consumption to the greatest possible extent, and ensures the running of normal operations.
