“…A solution to the above described problem is presented in [4]. The authors, in order to overcome the one-to-one relationship between a single subscriber and a GPRS Tunneling Protocol (GTP) tunnel that is inherent to the hierarchical routing in UMTS, implement a Multicast-Packet Data Protocol (M-PDP) context for each multicast group in the GGSN and SGSN.…”

In this paper, we present an efficient scheme for the multicast transmission of the data in the Universal Mobile Telecommunications System (UMTS). We take advantage of the tree topology of the examined network and we introduce the use of Routing Lists (RLs) in the nodes of the UMTS. The adoption of these lists leads to the decrement of the transmitted packets and to the efficient use of network resources in the multicast transmission of the data. We describe in detail the appropriate steps for the successful multicast transfer of data. Furthermore, we analyze the handling of special cases such as user mobility scenarios. Especially, the various handover types are examined along with the Serving Radio Network Subsystem relocation procedure. Finally, we implement our approach in the NS-2 simulator and we present the performance of the multicast mechanism.

“…The construction of a source-rooted shortestpath tree over such a topology is trivial and may be achieved by transmitting only a single packet over the paths that are shared by several multicast recipients. However, as a result of user mobility, there are several cases where this simplified view of the mobile network is violated [3,4].…”

Abstract-Based on multimedia broadcast/multicast service architecture(MBMS), this paper proposes an efficient QoS-based multicast approach for the Universal Mobile Telecommunications System (UMTS). Our approach adopts the existing scalablecoding technique to provide multiple levels of service quality to diverse mobile devices in the UMTS system. In this approach, two kinds of transmission modes are developed to utilize fully the network resources for wireline and wireless links. An analytic model is presented to investigate the performance of our approach and the 3GPP 23.246 approach. The numerical results indicate that in terms of transmission costs of core/radio networks, our approach outperforms the 3GPP 23.246 approach.

“…In [1], the authors discuss the use of commonly deployed IP multicast protocols in UMTS networks. However, in [2] the authors do not adopt the use of IP multicast protocols for multicast routing in UMTS and present an alternative solution. The scheme presented in [2] can be implemented within the existing network nodes with only trivial changes to the standard location update and packet-forwarding procedures.…”

Furthermore in [3], a multicast mechanism for circuit-switched GSM and UMTS networks is outlined while in [4] an end to end multicast mechanism for software upgrades in UMTS is analyzed.…”

Abstract. In this paper, a multicast scheme for UMTS which only requires insignificant modifications in the current UMTS network infrastructure is analyzed. We analytically present the multicast routing mechanism behind our scheme as well as the multicast group management functionality of it. Furthermore, we present an evaluation of our scheme in terms of its performance. The critical parameters for the evaluation of the scheme are the number of multicast users within the multicast group, the amount of data sent to the multicast users, the density of the multicast users within the cells and the type of transport channel used for the transmission of the multicast data over the air.
