Wireless device and method therein for enabling reflective quality of service (qos)

A method performed by a wireless device for enabling reflective Quality-of-Service, QoS, to a bi-directional communications flow in a wireless communications network, the method comprising:

• receiving a downlink, DL, data packet of the bi-directional communications flow indicating that reflective QoS is to be applied and comprising a DL Security Parameter Index, SPI, for an IPsec Security Association, SA, used in the DL direction, where the type of bi-directional communications flow is an IPsec protected communication;
• determining to create a new Packet Filter Set of a reflective QoS rule for corresponding uplink, UL, data packets of the IPsec communication;
• and
• obtaining by querying a local database in the wireless device, a UL SPI for a corresponding IPsec SA used in the UL direction for the UL data packets of the IPsec protected communication using the DL SPI and the fact that the bi-directional communication is an IPsec protected communication, where the UL SPI shall be used instead of the DL SPI for the UL data packets.
