This document contains significant port
12、ions 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 provide these s
13、ervices consists of radio channels typically used for Advanced Mobile Phone System (AMPS) cellular service. Document Structure This 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 Digital Pack
14、et Data System Specification is as follows: o Introduction and Overview 841-iii TINEIA-732-841 SNDCP PICS Proforma This document provides an overview of the CDPD Network and serves as a guide to the remainder of the system specification for specific detailed information. In this Part, design objecti
15、ves 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, major network elements and network services. A listing of key identifiers in CDPD is then followed by a comprehensive glossary
16、 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. Part 300 to Part 799-Protocols and Interfaces These Parts form the heart of the CDPD System Specification. They define the communication
17、s architecture of CDPD, including communications layer entities, services, protocol stacks, the three key interfaces, Radio Resource Control, Mobility Management, Accounting Management, Support Services and Network Management. Part 800 to Part 899-Supplementary Protocol Information These Parts conta
18、in further specification of the primary CDPD protocols. State transition matrices are used to define protocol state machines, and Protocol Implementation Conformance Statements (PICS) are provided for implementors. Part 900 to Part 999-Protocol Test Specifications Following an overview of protocol t
19、esting, these Parts contain Abstract Test Suites (ATSs) and Protocol Implementation extra Information for Test (PIXIT) for the protocols specified in Part 300 to Part 799. Part 1000 to Part 1999-Guidelines for Service Providers These Parts describe guidelines for CDPD Service Providers. 841 -iV Intr
20、oduction TINEIA-732-841 PART 841 SNDCP PICS Proforma 1 I n t ro d u ct i o n To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and options have been implemented for a given protocol. Such a statement is called a Protocol Implementation
21、Conformance Statement (PICS). 2 Scope This Part provides the PICS proforma for Part 404 in compliance with the relevant requirements and in accordance with the relevant guidance given in IS0-96461. This PICS proforma applies to both the user side and network side CDPD SNDCP interfaces. The user side
22、 interface can only be an M-ES. The network side of the interface can only be an MD-IS. 3 Su pp I i er Act ion The supplier of a protocol implementation claiming to conform to Part 404 is required to complete this PICS proforma, and is required to provide the information necessary to fully identify
23、both the supplier and the implementation. 841 -1 TINEIA-732-841 SNDCP PICS Proforma 4 PICS 4.1 A completed PICS proforma, including Additional Information and Exception Information, is the PICS for the implementation in question. The completed PICS specifies the implementations capabilities and opti
24、onal features. It also specifies any omitted features. This ensures that the implementation can be tested for conformance against relevant requirements, and against those requirements only. PICS Purpose The PICS serves a number of functions, including: Identifies the equipment under test Identifies
25、the conformance tests applicable to a given product based on answers provided in the PICS Is used during the static conformance review Is provided in a standard format Allows vendors/manufacturers to supply IUT information in a standardized manner (this benefits both VendorsManufacturers and Testing
26、 Agencies) Benefits Abstract Test Suite developers, as they can determine whether all relevant parameters have been identified and adequately tested Benefits the protocol implementor, as it clearly identifies which protocol capabilities are Mandatory, Optional, Conditionally Mandatory or Conditional
27、ly Optional. This reduces the risk of failing to conform to the standard through implementation oversight or misunderstanding. Benefits suppliers and potential purchasers of protocol implementations, as the PICS provides a detailed indication of capabilities claimed to be supported by an IUT Benefit
28、s users, as it can be used to do preliminary evaluations of IUT interworking. Although interworking can never be guaranteed, failure to interwork can often be identified by comparing the PICS of IUTs considered for interworking. 5 Abbreviations and Special Symbols This section presents summary lists
29、 of the symbols used in a PICS. 841 -2 Abbreviations and Special Symbols TINEIA-732-841 5.1 Status Symbols 5.2 M Mandatory NIA Not Applicable O Optional O.ci Optional, but, if chosen, support is required for either at least one or only one of the options in the group labelled by the same numeral P P
30、rohibited A. instead, the supplier shall write the missing answer into the Support column, together with an Xci reference to an item of Exception Information, and shall provide the appropriate rationale in the Exception Information item itself. An implementation for which an Exception Information it
31、em is required in this way does not conform to this Standard. Note-A possible reason for the situation described above is that a defect in the standard has been reported, a correction for which is expected to change the requirement not met by the implementation. Conditional Status The PICS proforma
32、contains conditional items. These are items for which the status-Mandatory, Optional or Prohibited-that applies is dependent upon whether or not certain other items are supported, or upon the values supported for other items. In many cases, whether or not the item applies at all is conditional in th
33、is way, as well as the status when the item does apply. Where a group of items is subject to the same condition for applicability, a separate preliminary question about the condition appears at the head of the group, with an instruction to skip to a later point in the questionnaire if the “Not Appli
34、cable” answer is selected. Otherwise, individual conditional items are indicated by one or more conditional symbols (on separate lines) in the Status column. A conditional symbol is of the form “cpred:cx” where “cpred” is a predicate and “cx” is one of the status symbols M,O, O.cn or X. If the value
35、 of the predicate in any line of a conditional item is true, then the conditional item is applicable, and its status is that indicated by the status symbol following the predicate; the answer column is to be marked in the usual way. If the value of a predicate is false, the Not Applicable (N/A) answ
36、er is to be marked in the relevant line. Each line in a multi-line conditional item should be marked; at most one line will require an answer other than N/A. 841 -7 TINEIA-732-841 SNDCP PICS Proforma 7.5 Predi cates 8 A predicate is one of the following: a. An item-reference for an item in the PICS
37、proforma. The value of the predicate is true if the item is marked as supported, and is false otherwise. b. A predicate name, for a predicate defined elsewhere in the PICS proforma (usually in the Protocol Capabilities section or at the end of the section containing the conditional item). See below.
38、 The logical negation symbol “ prefixed to an item-reference or predicate name. The value of the predicate is true if the value of the predicate formed by omitting the “ is false, and vice versa. c. The definition for a predicate name is one of the following: a. An item-reference, evaluated as at (a
39、) above b. A relation containing a comparison operator (=, c, etc.) with at least one of its operands being an item-reference for an item taking numerical values as its answer. The predicate is true if the relation holds when each item-reference is replaced by the value entered in the Support column
40、 as an answer to the item referred to. A Boolean expression constructed by combining simple predicates, as in (a) and (b), using the Boolean operators AND, OR and NOT, and parentheses, in the usual way. The value of such a predicate is true if the Boolean expression evaluates to true when the simple
41、 predicates are interpreted as described above. c. Each item whose reference is used in a predicate or predicate definition is indicated by an asterisk in the Item column. Global Statement of Conformance The implementation specified in this PICS meets all the mandatory requirements of the referenced
42、 standards: Note-Answering “No” or providing an exception condition to this question indicates non-conformance to Part 404 specification. Non- supported mandatory capabilities are to be listed in the PICS below, with an explanation for the abnormal status of the implementation (to be provided in the
43、 Exceptional Information table partition). 841 -8 Identification TINEIA-732-841 TABLE 841-1 Statement of Conformance 9 Name (please print) Signature Date The client will have fully complied with the requirements for a statement of conformance by completing the statement contained in this section.
