An important point with regard to providing QoS is to reduce signaling and interference. With this, operators can properly manage resources without such problems, in order to improve the services provided to users.
In this new scenario, the traffic generated from the UE to the eNodeB is deflected by an IP network before reaching the mobile network. The transmission of a information packet over an IP network is susceptible to delays, so the femto-cell may experience problems for obtaining an immune base time to jitter. Operators should ensure the concept of QoS in femto-cells, the parameters of these scenarios should be comparable to those offered by the macro-cells.
