scope:

The present document is intended to review the standardization issues with respect to services and architectures for Broadband Satellite Multimedia (BSM). The present document builds on the following two earlier reports:

• TR 101 374-1 [i]: "Survey on Standardization Objectives for Broadband Satellite Multimedia"

• TR 101 374-2 [2]: "Standardization Objectives for Broadband Satellite Multimedia: The Standardization Scenario".

The present document discusses the standardization approach, relevant issues, actions and further work that should be undertaken within ETSI in the following areas:

• BSM reference architectures and models;

• BSM bearer services;

• BSM interfaces.

The present document is intended to assess the possible role that Broadband Satellite Multimedia systems may have, which services they can provide, which existing standards they can use and which standards should be developed. The objectives of BSM standardization are:

• to enable users to access a wide range of telecommunications services, including many that are today undefined, with particular emphasis on multi-media services and high data rates;

• to provide an efficient means of using network resources (particularly radio spectrum);

• to facilitate the provision of a high quality of service similar to that provided by fixed networks;

• to facilitate the provision of easy to use, low cost terminals.
