....that will take into consideration service differentiation as well as the related QoS negotiated between the user and the network for a specific service. Several pricing models and billing schemes for broadband networks such as ATM networks [4] 5] as well as for IP networks have been proposed [6] [7] In this paper we suggest a sophisticated billing scheme that is based on the pricing concepts proposed for other types of networks, and attempts to merge their key features for third generation mobile systems. The suggested scheme fulfils the particular requirements of the mobile users and ....

....users and the accounting process related to the VASPs. III.BILLING SCHEME Since the number of players involved in the service provision increases, service revenues should be shared between them. This imposes the need to break the charge into two parts, the transport part and the service part [5][6]. The transport part is the basic charge for the network resources usage and includes parameters such as volume of transmitted data, duration, QoS and tariff zone, which are taken into account during the calculation of the transport bill. The service part is the premium rate charge for the service ....

....do not need to be physically present in the same location, allowing rural students to have the same opportunity for education as urban students. Among others, real time transmission of voice over the Internet, also known as Internet telephony, is attracting an increasing amount of attention [3][4][5] Many architectures and signaling protocols are proposed in [6] 7] 8] to provide the Internet telephony service. The reason for the importance of Internet telephony is that Internet telephony has the potential to significantly reduce the cost of long distance voice communication. Additionally, ....

....Internet. I. INTRODUCTION Internet telephony is experiencing significant growth, prompted initially by low price long distance calls [1] Longer term growth will be motivated by the greater service flexibility offered by IP networks, compared to the Public Switched Telephone Network (PSTN) [2]. This flexibility arises from the increased signaling capability of IP end systems compared to current handsets, as well as the ability to support multiple media types. To be widely accepted however, Internet telephony QOS must match or exceed that of the PSTN. From a user s perspective, the ....

....A major thrust of Internet telephony research has been protocol development. H.323 [12] and SIP [13] 15] 16] have emerged as the key peer to peer call setup protocols, with G.729 and G.723.1 the leading low bit rate audio codecs. Current protocol issues include billing, address resolution [2] and resource allocation [17] QOS arising from the established and developing protocols remains a key issue. Initial Internet telephony QOS research has considered voice quality arising from deployment of the new codecs over the public Internet. Kostas et al. 18] generate UDP trace records over ....
