Foreword This Technical Specification (TS) has be
42、en produced by ETSI Project Broadband Radio Access Networks (BRAN). The present document describes the basic data transport functions of the Data Link Control (DLC) layer for fixed wireless access systems above 11 GHz according to the High Performance Radio Access (HIPERACCESS) project. Separate ETS
43、I documents provide details of the system overview, the PHYsical (PHY) layer, the Convergence Layer (CL) and the conformance test requirements defined for HIPERACCESS. For the purpose of the present document, a “system“ constitutes the PHY and DLC layers, which are independent of the core network, a
44、nd the core network specific convergence layers. It should be noted that to specify a complete system, other specifications, e.g. for the network layer and higher layers are required. These specifications are assumed to be available or to be developed by other bodies. Introduction The main field of
45、application of HIPERACCESS systems is to provide access to a broad range of core networks including ATM, IP, PSTN, PDN, etc. By means of a Point-to-Multipoint (PMP) architecture the network service area may cover scattered subscriber locations. The systems may be applied to build new access networks
46、 by means of a multi-cellular architecture, covering both suburban, urban and regional areas. Subscribers are offered the full range of services by the particular public or private network. Subscribers will have access to these services by means of the various standardized user network interfaces. H
47、IPERACCESS systems provide standard network interfaces and transparently connect subscribers to the appropriate network node. These systems allow a service to be connected to a number of subscribers ranging from a few to several thousand, and over a wide range of distances, e.g. up to 2 km to 5 km.
48、The essential features of a HIPERACCESS system are: efficient use of the radio spectrum; high multiplex gain; maintaining QoS. Radio is often the ideal way of obtaining communications at low cost and difficult topography. Moreover, a small number of sites are required for these installations, thus f
49、acilitating rapid implementation and minimizing maintenance requirements of the systems. Multiplexing means that m subscribers can share n radio channels (m being larger than n), allowing a better use to be made of the available frequency spectrum and at a lower equipment cost. The term “multi-access“ derives from the fact that every subscriber has access to every channel (instead of a fixed assignment as in most multiplex systems). When a call or service is initiated the required resource is allocated to it. When the call or service is terminated, the resource is released
