General Description

This chapter defines requirements for support of high speed packet data transmission capability on TIA/EIA-95-B spread spectrum systems. Packet data transmission is supported on TIA/EIA-95-B Traffic Channels using primary or secondary traffic. For packet data transmission using TIA/EIA-95-B Traffic Channels, the Radio Link Protocol Type 2 specified in IS-707-A.8 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.

Packet data service options provide a means of establishing and maintaining Traffic Channels for packet data service. Service Options 22, 23, 24, and 25 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 Options 26, 27, 28, and 29 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.
