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.

The protocol in the Session Control Plane is illustrated in
Figure 1-1

The protocol of the Session Control Plane is a control protocols
and thus do not process packets.
