In this paper we propose novel network architecture for next generation 5G mobile networks. The proposed architecture is based on user-centric mobile concept in heterogeneous wireless environment. The implementation of the proposed architecture is performed in the service stratum, while the radio access technologies belong to the transport stratum regarding the Next Generation Networks approach. In the proposed architecture the mobile terminal has the possibility to change the Radio Access Technology - RAT based on certain user criteria. For the purpose of transparent change of the RATs by the mobile terminal, we introduce so-called Policy-Router as a new node in the core network, which establishes IP tunnels to the mobile terminal via different available RATs to the terminal. The selection of the RAT is performed by the mobile terminal using user agent for multi-criteria decision making, which is using the newly defined QoS policy-based routing procedure.
