Introduction

This Part is directed towards service providers and manufacturers intending to build or deploy equipment for use in the Cellular Digital Packet Data (CDPD) internal network. This Part does not directly impact CDPD subscribers or Mobile End System (M-ES)manufacturers.

This Part assumes that the reader is familiar with CDPD in general, as presented in [IS-732-100].

In order to properly function, the CDPD Network needs information about CDPD subscribers such as:

• The subscriber's identity

• Limitations Imposed on the subscriber

• End Systems associated with the subscriber

• Subscriber's billing status

• Accounting information associated with the subscriber.

The CDPD Subscriber Directory Profile is used for:

• Controlling the subscriber's access to CDPD resources

The CDPDSUBSCRIBERSERVICEFEATURES realizes the information object for a CDPD subscriber. This information may be used to control the subscriber's access to CDPD resources. Support of CDPDSUBSCRIBERSERVICEFEATURES is not mandatory but is recommended. Other mechanisms may be used to implement a Service Provider's access control policies.

• Providing information to assist realization of CDPD Support Services

THE CDPDSUBSCRIBERSUPPORTINFO realizes the information object needed to support CDPD accounting and location services. Support of CDPDSUBSCRIBERSUPPORTINFO is not mandatory but is recommended. [IS- 732-630] specifies how this information is used to support CDPD accounting.

This Part enumerates the specific features of Directory User Agents (DUA) and Directory System Agents (DSA) that may be used for this particular application of Directory Services. General requirements for CDPD DUAs and DSAs are defined in Part 1013.

The information about the CDPD subscriber is maintained in the CDPD Directory. DUA implementations conforming to the CDPD Subscriber Profile may be used to access the CDPD subscriber information.
