چکیده

Building new UMTS (Universal Mobile Telecommunication Systems) based networks seems to be on time. Nowadays the UMTS network design related problems are moving to the interconnection of Radio Network Controllers (RNC), placement of Media Gateways (MGw) and planning of the core network topology. This new area of UMTS network design is studied in the paper. A new algorithm is proposed for the above tasks, which based on efficient meta–heuristics, but applies some problem related features to obtain as good solution as possible. The paper overviews the UMTS core network structure, a possible abstraction of the real network and equipment from the viewpoint of network planning are proposed, furthermore the design algorithm is outlined and a detailed performance analysis is proposed using some network scenarios. It is important to note, that the abstract model enables the application of the proposed algorithm for the same type of design task, but in different technology background.

Optimizing the Traffic of Voice Core Domain in UMTS Network through RNC Re-homing

The past few years have seen mobile operators transition to next-generation mobile networks, specifically from third-generation networks (3G) to long term evolution (LTE). This paper describes the basic architecture and topology of UMTS R4 core network and introduces two options in network planning, i.e., flat structure or layered structure. This paper introduces the re-homing of radio network ...

Evolving core networks from GSM to UMTS R4 version

More than 217 UMTS licenses have been issued by June 2007. Mobile operators, especially those with GSM legacy networks, prefer UMTS R4 technique to evolve their existing 2G GSM networks. UMTS R4 technique provides a smooth path to bridge legacy TDM-based network to an IP-based soft-switched network. This paper describes the basic architecture and topology of UMTS R4 core network and introduces ...

A Dimensioning Study for UMTS Core Networks

ABSTRACT The current literature provides many practical tools or theoretical methods to design, plan, and dimension Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) radio networks but overlooks the algorithms of the network planning and dimensioning for core networks of GSM, UMTS and IP Multimedia Subsystem (IMS). This paper introduces an algor...

Common radio resource management for WLAN-UMTS integration at radio access level

WLAN-UMTS integration in the UMTS-based approach can be performed either at the UMTS Core Network (CN) or Radio Access Network (UTRAN). Both interworking solutions provide the operator with additional license-free bandwidth and promise good handover performance. Integration at the radio access level has the advantage that the UMTS core network protocols remain unaffected and the interworking ar...
