TIA ANSI/TIA/EIA-732-1023

Introduction

[TIA/EIA-732-630] describes the CDPD Layer 3 usage accounting information and the protocol for exchanging that accounting information between CDPD Service Providers. The accounting information is exchanged as Home Accounting Segments (HASs) between Serving Service Providers and Primary and Routing Service Providers. (See Figure 1023-1)

HASs are sent as an X.400 InterPersonal Message (IPM) within an External Body Part (see [TIA/EIA-732-620]).

This Part describes the mechanism for exchanging summary and settlement information between Service Providers. Summary information includes the results of rating and taxing the usage activity as recorded in HASs. It also includes charges for other activities. Inter-Service Provider settlement is enabled by the exchange of settlement information.

In addition, this Part describes the edits and returns process associated with the exchange of HASs, Summary Segments and Settlement Segments.
