TIA TIA-1121.007-1

INTRODUCTION

General Overview

The Session Control Plane contain the protocol used to negotiate a session between the access terminal and the access network.

A session is a shared state maintained between the access terminal and the access network, including information such as:

• A unicast address (UATI) and Paging Identifier (PagingID) assigned to the access terminal,

• the set of protocols used by the access terminal and the access network to communicate over the air-link, and

• configuration settings for these protocols (e.g., authentication keys, parameters for Connection Layer and MAC Layer protocols, etc.)

During a single session the access terminal and the access network can open and close a connection multiple times; therefore, sessions will be closed rarely, and only on occasions such as the access terminal leaving the coverage area or such as prolonged periods in which the access terminal is unavailable.

The Session Control Plane contains the following protocol:

• Session Control Protocol: This protocol provides the means to provision the protocols used during the session, and negotiates the configuration parameters for these protocols. In addition, this protocol ensures the session is still valid and manages closing of the session.
