TIA TIA-2000.4-E

FOREWORD AND SCOPE

(This foreword and scope is not part of this standard) This Specification was prepared by Technical Specification Group C of the Third Generation Partnership Project 2 (3GPP2). This Specification contains the Layer 2 Link Access Control (LAC) layer of the IMT-2000 CDMA Multi-Carrier Mode, IMT-2000 CDMA MC, also known as cdma2000®1 . It provides a specification for land mobile wireless systems based upon cellular principles. This Specification includes the capabilities of Telecommunications Industry Association Standard TIA/EIA-95-B.

This Specification provides the Layer 2 Link Access Control (LAC) signaling protocol architecture and functionality used to provide the transport and delivery of Layer 3 signaling messages over IMT-2000 CDMA MC air interface; however, other specifications are required to complete the air interface and the rest of the system. Some of these specifications are listed in the References section.

In this document, the term "Layer 2" is understood to mean the signaling Layer 2, in the sense that non-signaling traffic (e.g., circuit or packet data) may have a different Layer 2 not described here. In addition, some traditional ISO Layer 2 functionality may be placed in the MAC Layer, but such functionality is not signaling-specific and thus is outside the scope of this document.

This document has the following organization:

1. Definitions and Conceptual Model. This section defines the terms and numeric information used in this standard, and describes the architectural and functional model used to develop cdma2000 LAC signaling.

2. Mobile Station Requirements. This section describes the requirements for cdma2000 mobile stations. A mobile station complying with these requirements will be able to operate in the CDMA mode with cdma2000 base stations complying with this document.

3. Base Station Requirements. This section describes the requirements for cdma2000 base stations. A base station complying with these requirements will be able to operate in the CDMA mode with cdma2000 mobile stations complying with this document.

Annex A. Timers and Constants. This normative annex contains tables that give specific values for the constant identifiers found in Section 2 and Section 3.

This standard includes provisions for future expansion of system capabilities.
