NGN is a new public telecommunication network based on IP technology and has achieved audio, video and data signal transmission and management, and can provide a variety of broadband applications and traditional telecom services. NGN needs a variety of technical support as well as in have made a very good development prospects at home and abroad.
The policy and charging control function is defined as PCC (policy and charging control) by 3GPP and SBBC (service based bearer control) by 3GPP2. It is valuable to establish an experimental testbed for PCC and SBBC to improve and verify the related performance. At present, we can make use of open source IMS (OSIMS) and UCT PCF to simulate 3GPP PCC, but there is no testbed for the policy control function...
Future wireless services are expected to provide data-rates in the order of 1 Gbps in local area and 100 Mbps in wide area. A very wide bandwidth is required to support such high rates, in the order of 100 MHz: this wideband will not be available for each operator, thus a shared access to the spectrum among operators is needed. An holistic approach to spectrum sharing is adopted in this paper: not...
This paper presents a new definition of service delivery platform based on recent industry standard activities at OMA (open mobile alliance): the OSE (OMA service environment). The proposed blueprint is consistent with NGN (next generation networks) as well as legacy networks. The SDP blueprint discussed in this paper follows SOA (service oriented architecture) principles and basic IT technologies...
The ePerSpace project intends to demonstrate the achievements of its R&D activities, including both the technical evaluation of the platform and the user acceptance assessment of the services delivered. In order to achieve this goal, two trial phases were planned: the first one, February-April 2005 (trial 1), which consisted of 5 separate sub-trials, and the final trials in the last months of...
