Cell relay packet routing

摘要

Systems and methodologies are described that facilitate packet routing among relay eNBs in a wireless network. A donor eNB can create at least a portion of a tunnel endpoint identifier (TEID) for a relay eNB communicating with a UE or other device. In addition, the relay eNB communicating with the UE can create a portion of the TEID. Upon receiving packets with a TEID, the donor eNB can route the packets to downstream eNBs based on the portion of the TEID that it created. Other downstream eNBs can continue to route packets to next hop eNBs based on the portion of the TEID created by the donor eNB or the downstream eNBs themselves. The relay eNB communicating with the UE can route packets to the UE based on the portion of the TEID it created and/or the portion created by the donor eNB.

1. A method, comprising:
receiving a packet from a network node comprising a tunnel endpoint identifier (TEID) that includes at least a portion generated by a donor evolved Node B (eNB) and a disparate portion generated by a relay eNB; determining a disparate network node to receive the packet based at least in part on the TEID; comparing the portion generated by the donor eNB to a routing table associating one or more TEID portions with identifiers of network nodes, wherein the determining the disparate network node is based at least in part on locating the portion generated by the donor eNB in the routing table; and transmitting the packet to the disparate network node.
