A method is provided performed by an access point (100) for handling uplink communication in a communication system comprising the access point and a wire line network node (110) connected via wire line to the access point. The method comprises receiving an encrypted and/or integrity protected packet data unit, PDU, from a user equipment, UE, (10, 11, 12) wirelessly connected to the access point and detecting type of the received PDU, the type of PDU being any of a signaling radio bearer type or a data radio bearer type. The method further comprises encapsulating the received PDU by setting a header to the PDU, which header comprises an identity indicating the detected type of PDU and an identity indicating source address and/or destination address of the PDU, and sending (208) the encapsulated PDU to the wire line network node. Provided is also a corresponding method performed in the wire line network node (110). |
