With the development of Mobile Communication Network, flat network architecture has become a study focus. The flat traffic transmission can effectively lighten the burden on the operators' core network. The LIPA (Local IP Access) and SIPTO (Selected IP Traffic Offload) proposed by 3GPP are the typical technologies in the horizontal structure evolution. Current offload policy for LIPA&SIPTO either uses a coarse control bringing high cost to both of operators and mobile terminals, or performs rather complex in practice. This paper proposes a flexible and effective offload policy mechanism (the traffic offload mechanism based on policy of bearer granularity, TOMBOBP) to support the LIPA&SIPTO solution in H(e)NB subsystem. By matching the traffic information to the defined policy in the H(e)NB, it performs offload evaluation very well.
