12、y the TR-45.6 Subcommittee of the TIA/EIA/TR-45 Committee.This document contains significant portions of material originally submitted by the Cellular Digital Packet Data Forum Inc.This document set constitutes the Cellular Digital Packet Data (CDPD) System Specification. CDPD is a technology intend
13、ed to provide packet data networking services to mobile hosts. The media used to provide these services consists of radio channels typically used for Advanced Mobile Phone System (AMPS) cellular service.Document StructureThis Standard is published as a series of Parts. Each Part contains information

21、4555657585960Introduction TIA/EIA-732-300PART 300 Communications Architecture1 IntroductionPart 301 to Part 312 specify the Cellular Digital Packet Data (CDPD) Network communications architecture. The CDPD Network communications architecture is based on the ISO layered communications reference model
22、. Part 301 provides a brief definition of the layered communications model. In addition, Part 301 introduces the concept of communications subprofiles. These subprofiles are used as building blocks to define the CDPD Network element communications profiles. The CDPD Network subprofiles are classifie
23、d into:a. Application subprofilesb. Lower layer subprofilesc. Subnetwork subprofiles.In Part 310, the CDPD Application subprofiles are specified. These include the CDPD Support Services subprofiles and the CDPD Application Services subprofiles. The CDPD Support Services subprofiles include:a. Networ
