Mapping MPLS into 802.11e (EDCA)

Hi

I do not know if I am asking something fool, but I would like map the MPLS TE Tunnels into EDCA priorities. I have deploy a small scenario with 2 WLANs a 1 ethernet segment. Over them, I have set 2 TE Tunnels for BE and VOIP traffic, which is classfied using the DSCP field in the ingress node.

When I do not use all the capacity of the TE Tunnel, all is ok and the delay keeps bounded. However, If I give more capacity to the TE Tunnel than the real capacity, both TU Tunnels use the wireless channel equally. I would like to know if there is any way to set higher priority to one of the TE Tunnels in the 802.11 link. Could I map DSCP field into EXP field, and then map it to EDCA in order to give more wifi transmission opporutnity to the most priority Tunnel?

Any idea?Thank you

Regards
