14、gnificant 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 intended to provide packet data networking services to mobile hosts. The media used to pr
15、ovide 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 pertaining to one aspect of the system.The functional structure of the Cellular Di
16、gital Packet Data System Specification is as follows:a71 Introduction and OverviewTIA/EIA-732-600 Network Support Services600iv123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960This document provides an overview of the CDPD Network and ser
17、ves as a guide to the remainder of the system specification for specific detailed information.In this Part, design objectives are described and are followed by the design concepts used to realize the stated objectives. The resultant network is then described in terms of its external interfaces, majo
18、r network elements and network services. A listing of key identifiers in CDPD is then followed by a comprehensive glossary of CDPD terms and a reference list of non-CDPD documents.This Part contains the detailed listing of all Parts of the Cellular Digital Packet Data Specifications.a71 Part 300 to
19、Part 799Protocols and InterfacesThese Parts form the heart of the CDPD System Specification. They define the communications architecture of CDPD, including communications layer entities, services, protocol stacks, the three key interfaces, Radio Resource Control, Mobility Management, Accounting Mana

23、onThis Part is directed toward Cellular Digital Packet Data (CDPD) Service Providers and manufacturers intending to build equipment for use in the CDPD internal network. This Part does not directly impact CDPD subscribers or Mobile End System (M-ES) manufacturers. This Part assumes that the reader i
24、s familiar with CDPD in general, as presented in Part 100. Part 100 provides a comprehensive glossary of CDPD terms. References to non-CDPD documents, shown in square brackets (e.g., CCITT-X.400), are also listed in Part 100, which provides a complete CDPD bibliography.The 600 series of the CDPD Sys
25、tem Specification defines the network support services within the CDPD Network. CDPD is a commercial public mobile data communications network, and as such, must provide additional services beyond those used by subscribers to allow successful operation of the network. This Part specifies the Message
26、 Handling Service, and the accounting functions and protocols.Although the CDPD Network supports multiple protocols at the Network Layer, all CDPD Network Support Services are based on ISO/OSI protocol suites.1.1 CDPD Support Services CategoriesThe two categories of CDPD Support Services are as foll

28、Services for CDPD Network Services.CDPD Network Application Support Services include the following:a71 Network Managementa71 Message Handling Services (MHS)a71 Accounting.1.1.1 Network ManagementThe CDPD Network provides comprehensive mobile data communication services to subscribers. To ensure a hi
29、gh level of network availability, the CDPD Network is designed to incorporate Network Management services that allow CDPD Service Providers to operate the network. The Network Management services provide timely information to the network operator to detect network faults, to exercise controls to cor
30、rect faults, and to configure the network for optimal operation.CDPD Network Management architecture and services are defined in the 700 series of the CDPD System Specification.1.1.2 Message Handling ServicesCDPD Message Handling Services (MHS), (Part 620) provides a generic message store and forwar
31、d service that is utilized by other CDPD Network Support Services (e.g., Accounting, Part 630).1.1.3 Accounting ServicesAccounting Services provide information on how the resources that provide CDPD Network Services are being used and by whom.CDPD Accounting Architecture and Services are defined in
32、Part 630. The CDPD Accounting Service collects network usage data for each subscriber to allow compilation for billing purposes. The data collected may include packet count, packet size, source and destination addresses, Cell-ID used by Mobile End Systems, approximate time of transmission, and so forth.The Accounting Service also may provide near real-time information of the network usage. This service facilitates Service Providers in providing up-to-date summary and settlement information on demand.1. Layer 3 CDPD Services.2. Layer 7 CDPD Services.
