Abstract:
A method of providing fraud protection mediation implemented by a home location register (HLR) for a mobile telephone system, the method comprising the steps of:(a) determining if authentication processing is supported by a subscriber's cellular phone, comprising the steps of:(a1) determining whether an area the subscriber is in supports authentication processing by accessing, in the HLR, a Mobile Switching Center ID Point Code Map (MPCM) file record associated with a Mobile Switching Center (MSC) to determine whether the MSC supports the authentication processing, and(a2) determining whether the subscriber has an active authentication by accessing a profile record of the subscriber in a SUBS file of the HLR;(b) determining if fraud protection processing is supported by the subscriber's cellular phone, comprising the steps of:(b1) determining whether the MSC supports the fraud protection processing by accessing the MPCM file record associated with the MSC, and(b2) determining whether the subscriber has fraud protection authorized by accessing the profile record of the subscriber;(c) determining whether fraud protection processing is bypassed for the HLR;(d) performing an authentication check on the subscriber's cellular phone if the authentication processing can be performed on the subscriber's cellular phone; and(e) if the authentication check is not performed, performing a fraud protection check on the subscriber's cellular phone if the fraud protection processing can be performed on the subscriber's cellular phone.
