TIA TIA/EIA/IS-657

Abstract

<strong>INTRODUCTION</strong> <br><strong>General Description</strong> <br>This standard defines requirements for support of packet data transmission capability on TIA/EIA/IS-95-A wideband spread spectrum systems. Packet data transmission is supported on TIA/EIA/IS-95-A and TSB74 Traffic Channels using primary or secondary traffic. For packet data transmission using TIA/EIA/IS-95-A or TSB74 Traffic Channels, the Radio Link Protocol specified in Chapter 3 of "TIA/EIA/IS-99 and 2.2.2 is used. <br>This standard specifies a packet data bearer service for communication between terminal equipment and a packet interworking function (IWF) via a base station/mobile switching center (BS/MSC). It provides procedures that can apply to multiple packet data services e.g.. CDPD and Mobile-IP. <br>Service Option 7 is used to request packet data service through an IWF supporting an Internet standard Point-to-Point Protocol (PPP) interface to network layer protocols (see 4.1 and 4.2). Service Option 8 is used to request packet data service through an IWF supporting CDPD data services over a PPP interface (see 4.3). Additional packet data service options may be defined in future revisions to select other types of IWF resources or services. <br>Packet data service options provide a means of establishing and maintaining Traffic Channels for packet data service. When the service negotiation procedures of TSB74 are used, packet data service can be carried as primary or as secondary traffic. When the service option negotiation procedures of TIA/EIA/IS-95-A or TSB74 are used, packet data service can be carried as primary traffic only.
