A method and device for distributing Internet access data in an access network

Abstract

The present disclosure discloses a method and an apparatus for offloading Internet data in an access network, which are used for solving the technical problems that in a Network Address Translation (NAT) offloading networking solution, the information obtained in a monitor mode is incomplete, offloading characteristics for distinguishing users cannot be provided and offloading strategies are separated from Quality of Service (QoS) strategies of a core network. The solution of the present disclosure includes: an offloading device judges whether a Radio Access Bearer (RAB) data flow needs offloading according to a specific value of a specific parameter in an RAB message; if the offloading is needed, NAT is performed and then the offloaded data is transmitted to the Internet; and if the offloading is not needed, the RAB data flow is transparently transmitted to the core network. In the present disclosure, the offloading judgment condition, which the offloading device is in accordance with, directly originates from the core network, and the core network can proactively obtain required user information, thus offloading judgment can be made correctly and completely as much as possible, and offloading judgment can be implemented with QoS strategies of the core network together, and there is no need to add new QoS management points being independent of the core network.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for offloading Internet access data in an access network. Background technique [0002] Currently, the structure of mobile communication networks is figure 1 As shown, under this network structure, the data flow of mobile users accessing the Internet must pass through the access network and the core network to enter the Internet (Internet). [0003] With the abundance of terrestrial transmission and the continuous decline of transmission costs, users’ demand for Internet traffic and delay requirements continue to increase, and a new type of networking is being formed. figure 2 It is a possible shunt network structure diagram. Under this network structure, mobile users can connect to the Internet through the core network through traditional channels, or connect to the IU interface (Interconnection point between an RNC or a BSCand a 3G Core Network). , The ...

Problems solved by technology

[0009] In view of this, the main purpose of the present invention is to provide a method and device for distributing Internet access data in the access network, which is used to solve the problem that in the NAT distribution network scheme, the monitoring method obtains incomplete information and cannot provide user-distinguished distribution. characteristics, as well as the technical issues of splitting the offload strategy and the QoS strategy of the core network
