Abstract: Embodiments of the present invention disclose a data transmission method and a related apparatus, which are used to implement compression of data transmitted on a backhaul to increase throughput of the backhaul. The method in the embodiments of the present invention includes: parsing a received Internet Protocol (IP) data packet to obtain a transmission network protocol header, a transmission tunneling protocol header, a user data protocol header, and user application layer data; compressing the transmission tunneling protocol header, the user data protocol header, and the user application layer data to obtain a compressed transmission network protocol payload; using the transmission network protocol header to encapsulate the compressed transmission network protocol payload to obtain a compressed IP data packet; and sending the compressed IP data packet to a decoding device in a core network or in a base station.

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.

Abstract: Embodiments of the present invention relate to a content delivery method and apparatus, and an access network device. The method includes: receiving, by a cache server in an access network, a service request sent by a user equipment, where the service request contains an address of a content server; if the service data requested by the user equipment is stored, sending the stored service data to the user equipment, modifying the address of the content server in the received service request into an address of the cache server, and sending the modified service request to a core network device; receiving the modified service request that is routed by the core network device to the cache server; and sending the stored service data to the cache server through the Internet, the core network device, and the access network device, and discarding, by the cache server, the service data.

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.

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.
