This feature is introduced in UMG8900 V100R001.

 

Summary:

When a mobile user dials a special emergency number, for example, the fire emergency number, police number, ambulance number, or the traffic accident number, the call is routed to the nearest corresponding emergency service center, according to the location of the base station (BS) to which the user belongs. Alarms can be generated for this type of calls, and whether a user is charged can be set. This feature complies with the 3GPP 22.003 "Circuit

Teleservices supported by a Public Land Mobile Network (PLMN)."

 

Benefits:

This feature provides emergency call for special services. Users can use emergency call for special services.

Dependency:

This feature requires the cooperation of the MSC server.

This feature is applicable to the VMSC, GMSC, and TMSC

Its a very useful service.

We have such emergency call implementation in our network where calls are linked to cell IDs before routing the particular call to the nearest call centre within that cell ID of caller, though this implementation wasnt done using the MGW special feature. I will check this more to see if it would be useful in enhancing our present implementation.

Thanks and informative.

I also think so Mr. benjamin.omeke.

This document is very well done

thanks for sharing.
