Gap Criteria

M

This IE specifies the criteria for a call to be subject to call gapping.

Gap Indicators

M

This IE indicates the gapping characteristics.

Control Type

This IE indicates the reason for activating call gapping.

The value "gsmSCF Overloaded" indicates that an automatic congestion detection and control mechanism in the gsmSCF has detected a congestion situation.

The value "Manually Initiated" indicates that the service and/or network/service management centre has detected a congestion situation, or any other situation that requires manually initiated controls.

The Control Type "Manually Initiated" will have priority over a "gsmSCF Overloaded" call gap.

Note that Non-IN controlled traffic control mechanism can also apply to an exchange with the gsmSSF functionality. As the non-IN controlled traffic control is within the MSC, this traffic control has implicit priority over the IN controlled traffic control. The non-IN controlled traffic control may also have some influence on the IN call. Therefore it is recommended to take measures to coordinate several traffic control mechanisms. The non-IN controlled traffic control and co-ordination of several traffic control mechanisms are out of the scope of the present document.
