queues

The investigation has covered buffer resource and queue management as main and the most important network traffic parameter and access control and overload mechanism. Network devices interaction model can performed by three levels:
-    physical layer;
-    protocols layer;
-    queues consolidating two previous levels.

In this paper the possibility of increasing quality of service for mobile operator based on using of Unlicensed Mobile Access-Advanced (UMA-A) technology has been substantiated. It has been proposed a new way of increasing the efficiency of resources allocation of convergent network. The use of UMA-A allows releasing part of the radio channel resources in the places where overloads are observed.
