    Abstract: Embodiments of the present invention provide a gateway system and a communication method. The gateway system includes: a control plane entity, connected or integrated with a mobility management network element, and configured to allocate an IP address to UE and configure a data path for connecting a user plane entity with an RAN, a PDN or another gateway; one or more user plane entities, located between the PDN and the RAN, independent of the control plane entity, configured to forward data on the data path configured by the control plane entity. The gateway system is composed of the control plane entity and the user plane entity which are independent of each other, the number of the user plane entities may be independently changed to adapt to the change of network traffic without replacing all gateway entities, the network deployment is more convenient and the cost is lower.

    Abstract: Embodiments of the present invention provide a method for processing information, a forwarding plane device and a control plane device. The method includes: receiving a data packet, and extracting characteristic information of the data packet; searching for context information corresponding to the characteristic information of the data packet; buffering or discarding the data packet if the context information is not found; and sending an event reporting message to a gateway control plane device, wherein the event reporting message carries the characteristic information of the data packet, so that the gateway control plane device acquires the context information corresponding to the characteristic information of the data packet. In this way, the gateway forwarding plane device can acquire context information to the greatest extent under the condition that the context information is lost, thereby ensuring accurate forwarding of the data packet to the greatest extent.
