Method and apparatus for providing fraud protection mediation in a mobile telephone system
First Claim
1. 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.

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.

4. A home location register (HLR) for providing fraud protection mediation in a mobile telephone system, comprising:
-
a first portion configured to determine if authentication processing is supported by a subscriber'"'"'s cellular phone, wherein the first portion includes; a first subportion configured to determine whether an area the subscriber is in supports authentication processing, and a second subportion configured to determine whether the subscriber has an active authentication; a second portion configured to determine if fraud protection processing is supported by the subscriber'"'"'s cellular phone, wherein the second portion includes a first part configured to determine whether a Mobile Switching Center (MSC) currently serving the subscriber'"'"'s cellular phone supports the fraud protection processing, and a second part configured to determine whether the subscriber has fraud protection authorized; a third portion configured to determine whether fraud protection processing is bypassed for the HLR; a fourth portion configured to perform an authentication check on the subscriber'"'"'s cellular phone if the authentication processing can be performed on the subscriber'"'"'s cellular phone; a fifth portion configured to perform a fraud protection check on the subscriber'"'"'s cellular phone if the authentication check is not performed and the fraud protection processing can be performed on the subscriber'"'"'s cellular phone; and a sixth portion configured to store a Mobile Switching Center ID Point Code Map (MPCM) file containing individual MSCs'"'"' file records and a SUBS file containing individual subscribers'"'"' profile records, wherein the first subportion of the first portion includes a component configured to access the MPCM file record associated with the MSC to determine whether the MSC supports the authentication processing; wherein the second subportion of the first portion includes a component configured to access a profile record of the subscriber in the SUBS file to determine whether the subscriber has an active authentication; wherein the first part of the second portion includes a component configured to access the MPCM file record associated with the MSC to determine whether the MSC supports the fraud protection processing; and wherein the second part of the second portion includes a component configured to access the profile record of the subscriber to determine whether the subscriber has fraud protection authorized. - View Dependent Claims (5, 6)
