Sending an AnyTimeInterrogation operation

<component localCID="1" type="Invoke" operationCode="anyTimeInterrogation">
        <subscriberIdentity>
                <imsi>890509840200</imsi>
        </subscriberIdentity>
        <requestedInfo>
                <locationInformation/>
                <subscriberState/>
        </requestedInfo>
        <gsmSCF-Address nature="international" plan="isdn">84042448952</gsmSCF-Address>
</component> 

The received response will look like this:

<component localCID=1" type="ResultLast" operationCode="anyTimeInterrogation">
	<subscriberInfo>
		<locationInformation>
			<ageOfLocationInformation>14</ageOfLocationInformation>
			<vlr-Number>89050900123</vlr-Number>
		</locationInformation>
		<subscriberState>
		      <assumedIdle/>
		</subscriberState>
	</subscriberInfo>
</component>

 		<subscriberState/>
	</requestedInfo>
       <gsmSCF-Address nature="international" plan="isdn">84042448952</gsmSCF-Address>
