mobile network

This article introduces the methods and techniques for improving of the spectral resources utilization effectiveness for GSM mobile network. We suggest the combined use of orthogonal multiplexing and dynamic frequency and channel allocation as an optimal solution for radio access network. Speech quality is an important measurement for the performance evaluation in a wireless mobile communication system since voice is still the most used service.

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.

In order to satisfy emerging user requirements in advanced services/applications, provided seamlessly, operators have to deploy complex network topologies of heterogeneous nature, where different Radio Access Technologies (RATs) co-exist in single composite network with shared resources. Network operator will have assign the appropriate RAT to perform the respective task, so as to achieve the required quality of service, cost-effectively. In such circumstances, there is a need in vertical handover – mechanism of transferring current connections from one radio access network to another.
