Abstract

In GSM Networks the Home Location Register (HLR) is the central repository of subscriber data. All changes to subscriber data for provision, removal and modification of services and facilities a subscriber is entitled to use is always done at the HLR. Most of the operator-initiated actions involve changes to more than one subscriber, typically thousands of subscribers. A change of user data in the HLR requires an update to other peer network elements (like VLR, SGSN and SGMSCF). This is achieved in GSM by a message know as the MAP-InsertSubscriberDate (ISD) towards the VLR and SGSN and MAP-NotifySubscriberDataModify (NSDM) towards the gsmSCFs. For example, if an operator modifies the data for 1000 subscribers, 1000 different ISDs are triggered towards the VLR/SGSN where these subscribers reside. This results in a lot of traffic between the HLR and the VLR/SGSN. A new set of MAP messages is proposed for the upload of data change via mass modifications. Instead of sending only one subscriber identity (e.g. IMSI, MSISDN) in the message, a list of subscriber identities or a range is specified. The peer network entities receiving this message will apply the specified modification on all the subscribers locally as specified in the message. See Fig. 1.
