35、arts are informative and discuss non-CDPD specific entities (such as Intermediate Systems), support services (such as directory 20134 Previous page is blank TIAEIWSB-87-2013 CDPD External Interfaces services, accounting summary and settlement procedures, authentication, etc.), value-added services (
36、such as subscriber location) and Service Provider issues (such as an interoperability test plan overview and parameter configuration). Part 1000 contains the detailed listing of all Parts of this TSB. Part 2000 to Part 2999-Guidelines for Manufacturers of CDPD equipment These Parts are informative a
37、nd discuss such concerns as CDPD-specific entities (such as Mobile End Systems (M-ESs), Mobile Data Base Stations (MDBSs) and Mobile Data Intermediate Systems (MD-ISS), external interfaces (such as that between the Subscriber Unit (SU) and the Subscriber Identity Module (SIM) and multicasts from the
38、 perspective of each of the participating entities. Part 3000 to Part 3999-Guidelines for the CDPD Network Information Center (NIC).

39、ntroduction TIAEIAKSB-87-2013 PART 2013 CDPD External Interfaces 1 Introduction 2 One of the primary objectives of the Cellular Digital Packet Data (CDPD) Network is to provide compatibility with existing networks and applications. This part provides recommendations for the Application Program Inter
40、faces (APIs) for CDPD Mobile End Systems (M-ESs). All of the recommended APIs are currently specified elsewhere and appear in commonly available products. It is expected that there will be new APIs developed for wireless data communications: however, it is outside the scope of this document to discu
41、ss future APIs. ME-S Overview CDPD M-ESs (i.e subscriber equipment) may be physically realized in many ways. Some examples are: o Custom devices Two-way messaging units designed for a specific task. These units may be installed in delivery trucks, taxi-cabs, service trucks, vending machines, and so
42、forth. The mobile and wireless applications and the application services shall be designed for the specific task and corporate requirements. 201 3-1 STD-EIA TSB87-2013-ENGL 3797 323Lib00 UbULLiSb O97 TIAEIAfTSB-87-2013 CDPD External Interfaces 3 Hand-held devices Small personal computers designed to
43、 provide the subscriber with numerous functions. The operating system, applications, and application services will probably be designed specifically for these devices. These devices are known as personal communicators, personal digital assistants (PDAs), etc. The CDPD Network access device can be a
44、separate unit that can be connected to a laptop through its serial port, a PCMCIA slot, or it can be a circuit board that plugs into an internal bus. This device would operate similar to wire-line modems. Business travelers wanting to access their corporate home networks with laptops currently gain
45、remote access via telephone lines in a variety of ways: o Character-based terminal emulation to a serial port on a multi-user system or terminal server o Remote control software that takes over a PC that is back in the office. All keyboard, mouse, and display I/O of the office PC are controlled by t
46、he remote PC. Remote node. The remote user dials in to a system that provides access to the home network. The remote user has the same functionality as though they were connected to the home network locally. This is, typically implemented using Point-to-Point Protocol (PPP) or Serial Line Internet P
47、rotocol (SLIP) over the telephone line connection. CDPD provides simultaneous multiple remote node access to one or more networks. Remote users can set up multiple connections to multiple networks by running a connection-oriented transport protocol over CDPD. o CDPD device for laptops a M-ES Applica
48、tion Program Interfaces Part 2010 describes how the M-ES consists of three functional subsystems: a Mobile Application Subsystem (MAS), a Subscriber Unit (SU), and a Subscriber Identity Module (SIM). In the following sections, references to the SU are referring to both the SU and SIM as an integrate
49、d unit. The concept of an API stack is introduced in Part 2010 to define a general separation point between the MAS application functions and the SU CDPD functions. APIs are interface specifications that define the types of data and commands that may be relayed from a program to another software program or a software-controlled device. Application programs are usually written to interact with specific APIs. If a system has APIs different from what an application requires, that application may not run without being modified. M-ES APIs may be inserted at various protocol layers. From
