Home Subscriber Server (HSS) IRI
Clause 10.5.1.1
- as a national option, a mobile terminal is authorized for service with another network operator or service provider; in that case, other related events are required as cancel location, register location, location information request from a third party’s node;
- as a national option, a REPORT record have to be generated when there is a HSS subscriber record change of IMSI or of MSISDN or IMEI triggered by a messages to or from the HSS;
