Abstract:
1. A method for handing over a user equipment (UE), comprising: a donor access node with which the UE is in communication via a relay node receiving context information from the relay node; and the donor access node using the context information to identify data packets that belong to the UE, wherein the context information includes at least one of: wherein the UE logical flow identifier is mapped to a combination of a UE and a radio bearer through radio resource signaling between the donor access node and the relay node, wherein the mapping is encoded in at least one RRC message; and wherein the donor access node is configured to support handing over the UE to a target access node using at least one of: a proxy S1 termination point at the access node; or an early S1 path switch from a first S1 path to a second S1 path, the first S1 path being terminated at the donor access and the second S1 path being terminated at the target access node and wherein the early S1 path switch comprises sending a path switch request before the handover of the UE to the target access node is complete.
