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.

Abstract: A method for providing a local traffic shortcut (LTS) in a packet-oriented mobile communication network comprising the steps of storing in a LTS-database the IP addresses of all devices served by at least one network node of said network along with a node-ID of the respective network node; receiving an IP data packet by a network node and extracting a destination IP-address from the received data packet; querying the LTS-database with the extracted destination IP-address of the received data packet to identify at least one network node for performing a local traffic shortcut (LTS); and establishing an LTS path with the identified network node.

Abstract: A network storage method, a switch device, and a controller are provided. The method is applicable to a controller based on OpenFlow protocol. The method includes: determining, by the controller, that a first switching equipment is to cache data requested by a first data packet; and notifying, by the controller, the first switching equipment to cache the data requested by the first data packet, and notifying the first switching equipment to establish a first flow table entry according to issued match information corresponding to the first data packet and issued action instruction information corresponding to the first data packet, wherein the action instruction information corresponding to the first data packet is adapted to instruct the first switching equipment to forward the data cached in the first switching equipment and requested by the first data packet.
