摘要： In an aspect, the present disclosure relates to a relay node (RN) operatively coupled with user equipment (UE), wherein the RN is configured to create one or more tunnels to enable transmission of data messages and control messages from the UE directly to a packet data network gateway (PGW). The present disclosure relates to methods and systems for tunneling user equipment (UE) traffic by creating one or more tunnels between a relay node (RN) and packet data network gateway (PGW) to prioritize control messages over data messages, wherein the one or more tunnels are created when the UE gets attached to the relay node (RN). Further, tunneling of the one or more control/non-access stratum (NAS) messages to the PGW can be performed over one of the higher priority tunnels such that when the NAS messages are received at the PGW or HGW, they can be forwarded to a mobility management entity (MME).
