This standard provides the specification for the interface which coincides with the Reference Point "A_ter" defined in the TR45 Network Reference Model shown in [20]. The scope of this standard includes the following topics:

Descriptions of the specified functional capabilities that provide wireless telecommunications services across the BS-BS interface as defined in the TR45 Network Reference Model;

Descriptions of the division of responsibility of the functions provided between the source BS and the target BS, without prescribing specific implementations;

Descriptions of the BS-BS interface standard that support DS-41 and cdma2000^®1 systems.

Purpose

The purpose of this document is to provide the standard for interfacing a Base Station (BS) with one or more BSs. This document defines the functional capabilities, including services and features, of the specified interface. These services and features are the defining characteristics that are the basis for the overall system standard.
