Automatic Code Gap

40、ping (ACG) is used to reduce the rate at which a network entity (NE), typically an MSC, sends service request messages to a service control function (SCF). ACG may be initiated in response to an SCF Overload condition and adjusted based on SCF congestion level. ACG may also be initiated for Service

41、Management independently of SCF overload. The SCF can specify that ACG controls be applied to query messages destined for a specific Point Code and Subsystem Number or for an SCCP Global Title. This Interim Standard builds on the following standards: ANSI TIA/EIA -664, Cellular Features Description;

48、ation of Automatic Code Gapping (ACG) for use in the Wireless Radiotelephone Service. ACG is used to reduce the rate at which a network entity, typically an MSC, sends service request messages to a service control function (SCF) network entity. ACG controls can be applied automatically by the SCF wh

49、en it is in overload. ACG controls can also be applied by an SCF for purposes of SCF service management. 1.1 GENERAL This document describes the ACG network capabilities and the intersystem operations to enable a wireless system to use ACG. 1.2 OBJECTIVE The purpose of this document is to describe the ACG network capabilities, and to specify the operation of ACG so that wireless systems can use ACG. 1.3 ORGANIZATION This document is organized as follows: Section 2 provides the modifications and additions to TIMEIA-664 “Cellular Features Description”
