Scope The scope of this document is to define the Packet Data Specification of the wideband air interface (WAI). The wideband air interface called Uw is the interface between the fixed network equipment (FNE

37、) and the subscriber units, or directly between subscriber units in a wideband system. The general wideband system model is shown in Figure 1 and illustrates the Radio to FNE Mode of operation. A Vehicular Repeater (VR) could additionally act as a relay between FS and MR when coverage limitations re

38、quire the use of this local coverage area extension.

39、del The Wideband Air Interface (WAI) reference point Uw is between the MRC and FNE, or MRC to MRC, and is used for wireless communications between these functional groups. OSI layers 1, 2, and 3 are the specified scope of the implementation of the Uw services. The PDS defines the lowest sublayer of

40、OSI layer 3 and directly interfaces with the LLC layer. This standard describes the services, protocol(s), and PDU formats used for the conveyance of IPv4 and IPv6 bearer service. This document specifies the operation of IPv4 or IPv6 in conjunction with the WAI in each of the three system configurat

41、ions. The wideband data Subnetwork Dependent Convergence Protocol (SNDCP) is a robust protocol that conditionally resides between the WAI and the Internet Protocol. The functions allocated to the PDS layer include the following major aspects: IP Version 4 Datagram Mapping to SNDCP and LLC Primitives

General Description The following sections provide a high level description of the basic functionality of the three packet switched data configurations th

49、at are supported in the specification. 3.1 Overview The IP bearer service allows two or more fixed or mobile end hosts to communicate via the wireless network. There are two versions of IP bearer service that are supported, IP version 4 (IPv4) and IP version 6 (IPv6). The services are characterized as either an IPv4 RFC791 or IPv6 RFC 2373 bearer service that provi
