Method and apparatus for providing fraud protection mediation in a mobile telephone system
First Claim
1. A computer-readable medium having stored thereon instructions which, when executed by a processor, cause the processor to perform the functions of:
- (a) determining whether an authentication processing can be performed on a subscriber'"'"'s cellular phone, comprising the functions 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 whether a fraud protection processing can be performed on the subscriber'"'"'s cellular phone, comprising the functions 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.

Abstract
The system and method of the present invention facilitates an improved Home Location Register (HLR) that includes a fraud protection mediation module for use in a mobile telephone system. The fraud protection mediation module operates in any one of the following situations: (1) a registration notice (REGNOT) is received by the HLR from a Mobile Switching Center (MSC) currently serving a subscriber in a roaming area; (2) a qualification request (QUALREQ) is received by the HLR from a serving MSC for obtaining a subscriber'"'"'s profile; and (3) the HLR sends a qualification directive to a serving MSC, with the updated or modified profile of the subscriber. By using the improved HLR of the present invention, a carrier may have the HLR bypass the fraud protection processing in areas that support authentication processing to provide convenience to the subscribers so that they do not have to enter their PINs to use their cellular phones. Alternatively, if authentication processing is available, the cellular carrier may use fraud protection processing as a backup protection measure.
