Full Description
ETSI TS 102 462 defines a BSM functional architecture required to provide multimedia Quality of Service to theend user. This architecture identifies the functional elements to allow QoS provision in BSM systems integrated withheterogeneous networks. It includes the interfaces of these elements to other QoS functional elements in adjacentnetworks and customer equipment, and in higher or lower protocol layers.The multimedia services targeted are based on the Internet Protocol (IP) and use the QoS capabilities of IP as far asnecessary, without relying on the support of other underlying protocols (such as MPLS). QoS for unicast rather thanmulticast services is the primary focus.
A key feature of the BSM architecture is the SI-SAP. The way in which the QoS functions interact across the SI-SAP isalso illustrated in the architecture.
The approach adopted is to define the following aspects in sequence: the QoS service requirements; the global QoS functional and network architecture requirements in which BSM systems will play a role; the detailed BSM QoS architecture of main functional blocks (ST's, etc.).Several architectural cases are illustrated for QoS provision. These cases are intended to show the potential evolutionfrom a simple QoS solution with quasi-static resource allocations to more sophisticated services with dynamic resourcereservation.
