A method and system for guaranteeing QoS between different radio networks is disclosed. The radio networks comprise a first network and a second network. The first network, operating in Diff-serv mode, comprises a user equipment (UE). The second network comprises an AAA server, a TTG, and a GGSN. In the method a request to the TTG is initialized by the UE. A first QoS parameter is mapped to an IP header by the UE, an authentication request is then sent to the AAA server. The first QoS parameter is mapped to a second QoS parameter, and a Create PDP context request is constructed with the second QoS parameter to the GGSN to request a PDP context and a GTP-U tunnel.
