The configuration information at the above-mentioned distributing strategy configuration requirement shunting useful family of website and association's process level, as carried out the process of RLC/MAC/PHY layer to the streamed data of subscriber equipment when shunting website.And in fact shunt the forward process that website may be only data, and do not carry out the process of protocol hierarchy.As (the Low Power Node of low power nodes in Fig. 3, LPN) transmission link may be there is no between 2 and macro station, so LPN2 needs to forward through LPN1 to the data of macro station, so can by increasing community ID by work flow forwarding method of the present invention, the information vague generalization more such as subscriber equipment (User Equipment, UE) ID.
When micro-station 1 with have the transmission link be directly communicated with between macro station, and when micro-station 2 and the transmission link be not directly communicated with between macro station, the communication data between all macro stations and micro-station 2 all needs to forward through micro-station 1.There is the communication link be directly connected indicated by the solid line in figure 3, do not have direct communication link represented by dashed line.In order to make forwarding address more accurate, in table 1, increase the information of community ID and subscriber equipment ID, detailed content is as shown in table 2.
| Community ID | Subscriber equipment ID | Logic channel ID | Shunting treatment station ID |
| Cell x | UE a | SRB1 | 0 |
| Cell x | UE b | SRB2 | 0 |
| Cell y | UE c | DRB1 | 1 |
| Cell y | UE d | DRB2 | 2 |
| Cell y | UE e | DRb3 | 2 |
