“…As can be seen from the figure, the model consists of a Network Switching Subsystem -NSS (MSC and HLRNLR) connected with a Base Station Subsystem -BSS (RNC and BS). All nodes use ATM as common transport platform and they are connected with the ATM links [2], [4]. The MSC (Mobile Switching Center) node is an ATM/AAL2 switch.…”

In this article we focus on the transport and switching part of third generation mobile access networks. At the moment, the second generation of mobile systems is sufficiently extended everywhere and can provide services to all mobile users. The next challenge in the development of digital mobile networks is the integration of data and voice services in a unique platform. It seems to be that Asynchronous Transfer Mode technology (ATM) will be the transport technology candidate to support both types of services (voice and data) and can therefore offer the flexibility required by the Third Generation Mobile Systems. ATM supports the very-low-bit-rate applications, which are typical of voice services. Used directly, however, it is inefficient. Therefore it is needed an adaptation level for ATM that provides an efficient transmission of variable length packets at low bit rate. The ATM Adaptation Layer type 2 (AAL2) has been chosen for the Third Generation Mobile Systems. Th is article identifies issues related to AAL2 as the gain obtained by multiplexing voice packets from different users on a single ATM connection, buffers requirements and both cell assembly and end-to-end delay

“…The benefit is that it leaves freedom in the future for new types of products, which utilize different core network solutions. The interested reader can refer to [13] for different views about the GRAN concept. The main focus of UMTS standardization will be on a UMTS radio access network (URAN) that can be connected to one core network, which may be based on GSM, narrowband ISDN (N-ISDN), broadband ISDN (B-ISDN), or packet data networks (PDNs) through interworking units (IWUs), as depicted in Fig.…”

n 1980 the mobile cellular era started. Mobile communications has experienced enormous growth during the last ten years. First-generation mobile systems such as AMPS, TACS, and NMT using analog transmission for speech services were introduced in the early '80s. Second-generation systems, which use digital transmission, were introduced in the late 1980s. Global System for Mobile Communications (GSM), Personal Digital Cellular (PDC), IS-136, and IS-95 are second-generation systems. The services offered by these systems cover speech and low-bit-rate data. The second-generation systems will further evolve toward third-generation systems to offer more advanced services such as medium-bit-rate (up to 100 kb/s) circuit-and packet-switched data. These evolved systems are referred to as generation 2.5.
