TIA TIA-2001.4-E-4

Scope

This standard provides the specification for the interface whichcoincides with the Reference Point “A” defined in the TR45 NetworkReference Model shown in [I-4] and with Reference point 48 asdefined in the Network Reference Model shown in [27]. The scope ofthis standard includes the following topics:

• Descriptions of the specified functional capabilities thatprovide wireless telecommunications services across the A1interface as defined in the TR45 Network Reference Model,
• Descriptions of the division of responsibility of the functionsprovided between the BS and the MSC, without prescribing specificimplementations,
• Descriptions of the A1 interface standard that support DS-41[7] and cdma2000^®1 systems,
• Descriptions of the specified functional capabilities thatprovide circuit-services across the packet transport based MSCe-BS(A1p) and MGW-BS (A2p) interfaces as defined in the NetworkReference Model shown in [27]. It should be noted that, for a givencall, the transcoder may or may not be in the MGW or BS. Thisprotocol definition is not limited by the location or existence ofthe transcoder in the bearer path,
• Descriptions of the division of responsibility of the functionsprovided between th1 e 2 BS and the MSCe and MGW withoutprescribing specific implementations.

1 cdma2000^® is the trademark for the technicalnomenclature for certain specifications and standards of theOrganizational Partners (OPs) of 3GPP2. Geographically (and as ofthe date of publication), cdma2000^® is a registeredtrademark of the Telecommunications Industry Association (TIA-USA)in the United States.

Purpose

The purpose of this document is to provide a standard forinterfacing a MSC with one or more Base Stations (BSs). Inaddition, this standard provides for interfacing a Mobile SwitchingCenter Emulation (MSCe) and a MGW to one or more BSs. This documentdefines the functional capabilities, including services andfeatures, of the specified interface. These services and featuresare the defining characteristics that are the basis for the overallsystem standard.
