Abstract

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.
