24、ation Layer subprofiles that operate in conjunction with the Cellular Digital Packet Data (CDPD) Network lower layer subprofiles to provide services that meet the CDPD Service Provider requirements. The primary reference for this Part is the Industry/Government Open System Specification IGOSS-1. The
25、 primary reference for the protocols in this Part is the Stable Implementation Agreements for Open Systems Interconnection Protocols OIW-1.1.1 Application Service Elements (ASEs)Application Service Elements (ASEs) provide common Application Layer services that allow the exchange of information among
26、 application processes within one or more of the application sub-profiles. The ASEs used by one or more of the CDPD Service Provider Network applications are described in the following subsections.1.1.1 Association Control Service Element (ACSE)The Association Control Service Element (ACSE) ISO-8650
27、 controls the association between two Application Entities; it is responsible for establishing and releasing an association. Certain information, such as the identity of the application processes and the supporting Application Service TIA/EIA-732-310 Application Subprofiles31021234567891011121314151

29、to invoke a remote operation on another computer, to have the result of the operation or an error message returned to the invoker, or to have the remote operation rejected as invalid. ROSE ISO-9072-2 may be used by the Common Management Information Protocol and the CCITT 1988 Message Handling System
30、s. 1.1.3 Reliable Transfer Service Element (RTSE)The Reliable Transfer Service Element (RTSE) provides the facilities to reliably transfer large amounts of data between distributed application processes. RTSE uses the Activity and Minor-synchronize functional units of the session layer to set checkp
31、oints in a large data string so that data transfer may be restarted at a convenient point if the underlying network connection breaks. RTSE ISO-9066-2 is optionally used by the CCITT 1988 Message Handling Systems application.2 Network ManagementThe CDPD Network Management application provides system
32、 monitoring and operation functions of the CDPD Network. Each CDPD Network element is managed through the use of cooperating ISO network management conformant applications. The upper layer CDPD Network Management applications are specified in Part 700 through Part 751. Network Management interchange
33、s between peer management entities are conducted through ISO conformant CDPD Common Management Information Services ISO-9596-1. The CDPD Network Management communication subprofile comprises the following:a. Common Management Information Protocolb. Remote Operation Service Elementc. Association Cont
34、rol Service Elementd. Connection Oriented Presentation Protocole. Connection Oriented Session Protocol.The CDPD Network Management I Subprofile is depicted in Figure 310-1. The optional management and operation of the CDPD Mobile End Systems (M-ESs) requires cooperative communications across the CDP
35、D Airlink Interface. The CDPD airlink subnetwork is a scarce resource that must be used efficiently. To conserve the airlink resource, the more limited but sufficient Simple Network Management Protocol version 2 (SNMPv2) 3103Message Transfer Systems TIA/EIA-732-31012345678910111213141516171819202122

The CDPD Network Management A subprofile is depicted in Figure 310-2.3 Message Transfer SystemsThe CDPD Network provides value added network services through the use of the CDPD Message
37、Transfer System (MTS).The CDPD-MTS conforms to the CCITT X.400 Message Handling System (MHS) standards suite.

A user may be an originator (sender of mes
40、sage) or a recipient (message receiver). A user may be a person or a computer process. User Agent (UA): UA is an application process that interacts with the MTS or a message store (MS) to submit messages on behalf of a user.Message Transfer System (MTS): The MTS delivers the messages submitted to it
41、, to one or more recipient UAs, access units (AU) or MSs, and may return notifications to the originator.Message Transfer Agents (MTA): The MTA operate together in a store and forward manner to transfer messages and deliver them to the intended recipients.Message Store (MS): The message store acts a
42、s an intermediary between the UA and MTA. Its primary purpose is to store and permit retrieval of delivered messages. The CDPD Message Handling Systems (MHSs) shall be implemented in accordance with the CCITT 1988 MHS Recommendations. Such MHSs provide significant additional services that are not fo
43、und in CCITT 1984 MHS implementations. The CCITT 1988 Recommendations also allow users significant flexibility in configuring their systems.The CDPD-MTS elements cooperate through communications using the two subprofiles. These are the MTS Reliable Transfer Application subprofile and the MTS Reliabl
44、e Access Application subprofile. These two services are depicted in Figure 310-4.The MTS Reliable Transfer Application subprofile comprises the following:FIGURE 310-3 MTS Functional ModelMTA MSUAMTAMTAMTAUAUAMTSUser3105Message Transfer Systems TIA/EIA-732-31012345678910111213141516171819202122232425
