METHOD AND SYSTEM FOR DATA TUNNELING IN DEVICE TO DEVICE COMMUNICATION ASSISTED BY A TELECOMMUNICATION NETWORK

A method for managing data packets (MAC PDUtx, RLC PDUtx) transmitted by a first user equipment (105tx) to be received by a second user equipment (105rx) through a radio network is proposed. The method comprising having the radio network comprising a radio transceiver station (110) configured for receiving data packets (MAC PDUtx; RLC PDUtx) transmitted by the first user equipment. For each data packet received, checking whether the data packet comprises a request for a data packet tunneling (TUN, LCID). For each data packet comprising a request for data packet tunneling, providing the data packet to a relay protocol entity (305) at a Radio Link Control protocol layer (215). The relay protocol entity is configured for generating at least one tunneling data packet (RLC PDUeNB; AM PDU), said generating at least one tunneling data packet comprises inserting at least a portion (625) of the transmitted data packet into the at least one tunneling data packet and transmitting the tunneling data packet to the second user equipment.
