Route maintenance and update based on connection identifier in multi-hop relay systems |
摘要 |
Connection ID (CID) assignment in multi-hop relay system can be used to perform routing. Using CID assignment as routing information in a multi-hop wireless relay system to maintain the routing structure is disclosed. In a CID cache scheme, a base station builds a CID cache based on the upstream packet and broadcasts the CID cache to a relay station. The CID cache comprises CIDs along with routing information. Based on CID cache the spanning tree of the routing can be reconstructed. A hierarchical CID assignment is disclosed wherein a base station assigns a range of CIDs to a relay station. A relay station can recognize its data packets and forward them to corresponding mobile stations. Maintaining routing automatically along with CID assignment is also disclosed. |
