Ip kinds of methods to achieve local business and systems

The present invention discloses a local IP-based service implemented by the system and method of the relay node types, the present invention is embedded in a local gateway to the relay node, the relay node or the local co-located with the gateway, the relay node or the local gateway via a wired connection, establishment of a packet data network between a local user equipment UE and the local PDN gateway via the relay node. By the present invention can support not only a local service or service between the adjacent relay node and the user equipment can support two or more local service or adjacent service user equipment via the relay node, to support local IP-based data streams widely used, reducing the load on the core network. Further, by using a short distance wireless channel, it is possible to improve spectral efficiency, to improve the throughput.
