METHOD, DEVICE AND SYSTEM FOR TRANSMITTING PACKET SERVICE DATA

摘要

The present invention discloses a method, device and system for transmitting packet service data. 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 invention, the problem is overcome that all packet service data transmitted by the user equipment need to be transmitted via a mobile backhaul, a radio network controller (RNC), a serving GPRS support node (SGSN), the IP backbone network and a gateway GPRS support node (GGSN) in the prior art, thereby saving the operation and maintenance cost of the packet network.
