Introduction The Next Generation Network (NGN) is seen as the future universal network based on IP into which dif

21、ferent network technologies will be integrated. The BSM network 1 is an example of one of these technologies. Working groups at ETSI (TISPAN), ITU and others (3GPP, TMF etc) have defined many of the functional characteristics of the NGN 4, 8, 9 and their work is continuing. The BSM network has been

22、defined with many of the same features (IP protocol based packetised transport, modular and interoperable control plane elements, a largely access agnostic architecture, etc.) necessary for compatibility with the NGN. Hence the BSM network is a candidate for NGN integration. The BSM system has also

23、been defined as a functional architecture to implement IP-based services in a standardised way over a variety of satellite technologies, and with the potential to operate these services when the BSM network is integrated into heterogeneous networks i.1, i.2. The BSM architecture is characterised by

24、the SI-SAP which defines the separation between common Satellite-Independent (SI) protocol layers and alternative lower Satellite-Dependent (SD) layers 2. In addition, interfaces with higher-layer protocols and peer external networks and customer equipment are provided where appropriate. This is als

25、o very compatible with the NGN architecture which wants to clearly distinguish between transport specific and service specific functions. One of the main functional building blocks of the NGN is the IP Multimedia Subsystem (IMS) 6. The IMS provides a means initially for fixed-mobile and now many net

26、work convergence and interworking functionality for IP-based services. These include today IPTV, fixed and mobile voice and presence, and potential new services like video conferencing, peer-peer gaming etc. in the future. The definition of the NGN and the specifications of the IMS core functionalit

27、y are still evolving in the standards bodies, but are sufficiently mature and stable to be able to define the potential interactions with the BSM network. Basic BSM network services could be deployed over the current IMS, but as IMS-based networks and applications mature, converged BSM services can

28、be offered in conjunction with other satellite and terrestrial wireline and wireless networks using a common subscriber management system and control plane. The present document will specify how BSM networks can be integrated into the NGN architecture. ETSI ETSI TS 102 855 V1.1.1 (2011-03)61 Scope T

29、he integration and interoperability of BSM networks with the NGN is specified in terms of the functional architecture and associated functions and interfaces. The present document is based on and uses TISPAN (release 2) definitions and terminology (since TISPAN release 3 is not yet fully specified).
