General Description

This chapter of IS-707 defines requirements for support of packet data transmission capability on TIA/EIA/IS-95 wideband spread spectrum systems. Packet data transmission is supported on TIA/EIA/IS-95 Traffic Channels using primary or secondary traffic. For packet data transmission using TIA/EIA/IS-95 Traffic Channels, the Non-Transparent Radio Link Protocol specified in IS-707.2 is used.

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.

Service Options 7, 4103 and 15 are 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, 4104 and 16 are 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.

Packet data service options provide a means of establishing and maintaining Traffic Channels for packet data service. When TIA/EIA/IS-95 service negotiation procedures 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 are used, packet data service can be carried as primary traffic only.
