<p>A processing method of invalidation of downlink data tunnel among networks is disclosed, the method includes: core network user plane anchor receives error indication of data tunnel sent from accessing network device. After deciding that user plane corresponding to the error indication uses one tunnel, the core network user plane anchor notifies specific core network control plane to request recovering downlink data tunnel. The core network control plane recovers the downlink data tunnel, and notifies the core network user plane anchor to update the information of user plane. A processing system and device of invalidation of downlink data tunnel among networks are also disclosed. The processing method, system and device can improve recovering the rate of data transferring after invalidation of downlink data tunnel.</p> |
