摘要：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.
