  • Publication number: 20120099438
    Abstract: A method, device and system for transmitting packet service data are provided. The method includes the steps of: receiving the packet service data transmitted by a user equipment; determining the packet service data to be uninstalled in the packet service data according to the service uninstall strategy of the user equipment; and transmitting the packet service data to be uninstalled to the packet data network via a metropolitan-area network and an internet protocol (IP) backbone network. By applying this method, the problem in the prior art is overcome, thereby saving the operation and maintenance cost of the packet network.

  • Publication number: 20120057550
    Abstract: The present disclosure relates to the communications field and discloses a method, an apparatus, and a system for transmitting packet service data Packet service data is sent by a User Equipment (UE). It is determined whether the packet service data is Internet service data according to a pre-obtained Internet service offloading policy. If the packet service data is Internet service data, the packet service data is transmitted to a Public Data Network (PDN) via a Metropolitan Area Network (MAN) and an IP backbone. Embodiments of the present disclosure may be applied to wireless communication systems such as a WCDMA system.

  • Publication number: 20110228676
    Abstract: The present invention discloses a communication network, device and method. The communication method includes the following steps: a Mobile Broadband Edge (MBB-Edge) node sends a traffic offloading indication to a NodeB according to a traffic offloading policy; and the NodeB directs User Plane (UP) data of a Packet Switched (PS) service to a Public Data Network (PDN) through a fixed broadband bearer network of an offloading path according to the traffic offloading indication. The present invention increases the transmission efficiency of PS services.
