Pre-paging (standard & non-standard “customized by Huawei”) and the related configuration in case of Ms unreachable or Power  off  Compatible with MSOFTX3000 V100R00C0!"0#!

Ordinary paging

For ordinary pre-paging no additional configuration to distinguish between IMSI detached & unreachable Callee as shown below:

If subscriber MS is power off then PRN res will carry IMSI detached as below there is no need for MSCb to send paging as !"Rb already has the dyna#ic infor#ation about the callee $IMSI detached%
