    Abstract: A data sharing method includes that a first network element receives a user data policy from a terminal device. The first network element obtains user information of the terminal device according to the user data policy. The first network element sends the user information of the terminal device to a second network element according to the user data policy.

    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 the data packet's characteristic information; searching for context information corresponding to the data packet's characteristic information; 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 data packet's characteristic information, so that the gateway control plane device acquires the context information corresponding to the data packet's characteristic information. forwarding of the data packet to the greatest extent.

    Abstract: Described herein is a method for processing an invalidation of a downlink data tunnel between networks. The method includes the following steps: (1) a core network user plane anchor receives an error indication of data tunnel sent from an access network device, (2) after deciding that the user plane corresponding to the error indication uses a One Tunnel technology, the core network user plane anchor notifies a relevant core network control plane to request recovering the downlink data tunnel, (3) the core network control plane recovers the downlink data tunnel and notifies the core network user plane anchor to update information of the user plane. In addition, a communication system and a communication device are also provided. The method, system, and device can improve the speed of recovering data transmission after the downlink data tunnel becomes invalid.

    Abstract: A method for user detachment when a handover or change occurs in a heterogeneous network is provided. The method includes: a user equipment (UE) is handed over or switched from a source network to a target network; a network element on a network side determines whether to detach the UE from the source network, and if yes, the network element on the network side detaches the UE from the source network. A system and a device for user detachment when a handover or change occurs in a heterogeneous network, and another method for user detachment when a handover or change occurs in a heterogeneous network are also provided.
