HOTLINE ROUTING OF PRE-ACTIVATED GSM SUBSCRIBERS USING PSEUDO-MSISDNs

Abstract

The present invention relates to hotline routing of calls originating from mobile stations. The hotline routing conserves MSISDNs for valid subscribers and provides a relatively generic solution. In one example, a computer system stores in a location register a subscriber profile with an IMSI and a pseudo-MSISDN. A mobile station (which includes a SIM with the IMSI) originates a call. After translation of the pseudo-MSISDN, a serving MSC routes the call to a service activation center.

1 . A computer-readable medium storing computer-executable instructions for causing a computer system programmed thereby to perform a method comprising:
 storing a subscriber profile including an IMSI and a pseudo-MSISDN in a location register, thereby facilitating hotline routing with translation of the pseudo-MSISDN for a call originating from a mobile station including a SIM with the IMSI.
