Scope

This standard provides the specification for the interface which
coincides with the Reference Point "A" defined in the TR45 Network
Reference Model shown in [I-2] and with Reference point 48 as
defined in the Network Reference Model shown in [25]. The scope of
this standard includes the following topics:

  • Descriptions of the specified
    functional capabilities that provide wireless telecommunications
    services across the A1 interface as defined in the TR45 Network
    Reference Model,
  • Descriptions of the division of
    responsibility of the functions provided between the BS and the
    MSC, without prescribing specific implementations,
  • Descriptions of the A1 interface
    standard that support DS-41 [7] and cdma2000®
    systems,
  • Descriptions of the specified
    functional capabilities that provide circuit-services across the
    packet transport based MSCe-BS (A1p) and MGW-BS (A2p) interfaces
    defined in the Network Reference Model shown in [25]. It should be
    noted that, for given call, the transcoder may or may not be in the
    MGW or BS. This protocol definition is not limited by the location
    or existence of the transcoder in the bearer path,
  • Descriptions of the division of
    responsibility of the functions provided between th1 e 2 BS and the
    MSCe and MGW without prescribing specific
    implementations.

cdma2000® is the trademark for the technical
nomenclature for certain specifications and standards of the
Organizational Partners (OPs) of 3GPP2. Geographically (and as of

Purpose

The purpose of this document is to provide a standard for
interfacing a MSC with one or more Base Stations (BSs). In
addition, this standard provides for interfacing a Mobile Switching
Center Emulation (MSCe) and a MGW to 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.
