In next generation communication networks, multiple access networks will coexist on a common service platform. In cases where network resource planning indicates that individual access network resources are insufficient to meet service demands, these networks can cooperate and combine their resources to form a unified network that satisfies these demands.(More)
MBMS bearer services can be provided in each cell by either Point-to-Point or Point-to-Multipoint transmission mode but for efficiency a decision has to be made between the two approaches. Initially, the fundamental criterion used to make this decision was the number of MBMS users in a cell (UE Counting). In this paper we extend our previous work, which(More)
—Future networks are envisioned to satisfy the user needs and improve their quality of experience. This requires the networks to support context-aware information, where context of the user, session, network and environment will greatly influence the way the session is delivered: new approaches are required to deal with the overall context information and(More)
The paper addresses the issue of achieving context-aware, adaptive multiparty sessions in a heterogeneous system by illustrating how to add elements of adaptivity and context-awareness to the session management functionality of such systems. The effective usage of situation/context information can lead to context-aware content casting, especially(More)
The article addresses context-aware, adaptive multiparty sessions in a heterogeneous system through such elements as adaptivity and context-awareness. The effective usage of context information can lead to context-aware content casting, especially context-aware, adaptive multicasting. Therefore, regarding the multicast service, the key functionality of an(More)
This paper presents a new system level simulator that has been developed to evaluate Radio Resource Management (RRM) techniques in UMTS (Universal Mobile Telecommunication Systems) and enhanced-UMTS networks. The simulator includes new implementations for the User Equipment, Node B, Radio Network Controller nodes and can evaluate parameters associated with(More)
