System and method of implementing a private charge rate in a radio telecommunications network
First Claim
1. A method of determining a charge rate for a call from a mobile station in a cellular telecommunications network in which a public system operates a macrocell which overlays a microcell operated by a private system, said method comprising the steps of:
- regularly sending a periodic signal from the private system to a mobile switching center (MSC) in the public system, said periodic signal indicating whether the private system is operating normally;
placing a private system status indication (PSSI) in a charging record generated by the MSC, said PSSI indicating whether the private system is operating normally;
placing an identity of the mobile station (MSID) and an identity of a cell where the call is placed (CELLID) in the charging record by the MSC;
sending the charging record from the MSC to a billing center;
determining from the MSID whether the mobile station belongs to the private system;
determining from the PSSI whether the private system is operating normally;
determining from the CELLID whether the call was placed in the overlying public system macrocell; and
charging the call at a preferential rate upon determining that the MS belongs to the private system, the private system is not operating normally, and the call was placed in the overlying public system macrocell.

Abstract
A system and method for determining a charge rate for a call from a mobile station in a cellular telecommunications network in which a public system operates a macrocell which overlays a microcell operated by a private system. The private system reports whether it is operating normally to a mobile switching center (MSC) in the public system. The MSC sends a charging record to a billing center and includes a private system status indication (PSSI) which indicates whether the private system is operating normally. The charging record also includes an identity of the mobile station (MSID) and an identity of the cell where the call is placed (CELLID). The billing center determines from the MSID whether the mobile station belongs to the private system, determines from the CELLID which cell the call was placed in, and determines from the PSSI whether the private system is operating normally. The call is charged at the preferential rate upon determining that the mobile station belongs to the private system, the call was placed in the public macrocell, and the private system is not operating normally.

5. A method of charging for a call from a mobile station which belongs to a private cellular system when the private system is inoperative, said private system operating a microcell which is overlaid by a macrocell in a public cellular system, said method comprising the steps of:
-
determining that the mobile station placed a call in the public macrocell; determining whether the private system is inoperative by sending a message from the private system to the public system providing a time period during which the private system was inoperative, said message being sent when the private system becomes operable; and charging for the call at a preferential rate charged for calls in the private system upon determining that the private system is inoperative. - View Dependent Claims (6)

7. A method of charging for a call from a mobile station which belongs to a private cellular system when degraded performance of the private system prevents the mobile station from accessing the private system, said private system operating a microcell which is overlaid by a macrocell in a public cellular system, said method comprising the steps of:
-
regularly sending a periodic signal from the private system to the public system, said signal reporting whether performance of the private system is degraded; determining that the mobile station placed a call in the public macrocell; determining whether the performance of the private system was degraded when the call was placed; and charging for the call at a preferential rate charged for calls in the private system upon determining that the performance of the private system was degraded when the call was placed. - View Dependent Claims (8)

9. A system for determining a charge rate for a call from a mobile station in a cellular telecommunications network in which a public system operates a macrocell which overlays a microcell operated by a private system, said system comprising:
-
means for reporting whether the private system is operating normally to a mobile switching center (MSC) in the public system, said reporting means regularly sending a periodic signal to the MSC reporting whether the private system is operating normally; means for sending a charging record from the MSC to a billing center, said charging record including; a private system status indication (PSSI) which indicates whether the private system is operating normally; an identity of the mobile station (MSID); and an identity of a cell where the call is placed (CELLID); means within the billing center for determining from the MSID whether the mobile station belongs to the private system; means within the billing center for determining from the CELLID which cell the call was placed in; means within the billing center for determining from the PSSI whether the private system is operating normally; and means for charging the call at the preferential rate upon determining that the mobile station belongs to the private system, the call was placed in the public macrocell, and the private system is not operating normally.

10. A billing center for determining a charge rate for a call involving a mobile station in a cellular telecommunications network in which a public system operates a macrocell which overlays a microcell operated by a private system, said billing center comprising:
-
means for receiving a charging record from the public system, said charging record including; a private system status indication (PSSI) which is automatically inserted in the charging record by the private system to indicate whether the private system is operating normally; an identity of the mobile station (MSID); and an identity of a cell where the MS is located (CELLID); means for determining from the MSID whether the mobile station belongs to the private system; means for determining from the CELLID which cell the MS was located in during the call; means for determining from the PSSI whether the private system is operating normally without having to request a private system status report; and means for charging the call at the preferential rate upon determining that the mobile station belongs to the private system, the MS was located in the public macrocell during the call, and the private system is not operating normally.

11. In a billing center, a method of determining a charge rate for a call involving a mobile station in a cellular telecommunications network in which a public system operates a macrocell which overlays a microcell operated by a private system, said method comprising the steps of:
-
receiving a charging record from the public system, said charging record including; a private system status indication (PSSI) which is automatically inserted in the charging record by the private system to indicate whether the private system is operating normally; an identity of the mobile station (MSID); and an identity of a cell where the MS is located (CELLID); checking the MSID in the charging record to determine whether the mobile station belongs to the private system; charging the call at a public rate upon determining that the mobile station does not belong to the private system; checking the CELLID in the charging record to determine which cell the call was placed in upon determining that the mobile station belongs to the private system; charging the call at a preferential rate upon determining that the call was placed in the private system microcell; checking the PSSI in the charging record to determine whether the private system is operating normally upon determining that the call was placed in the public system macrocell, said step of checking the PSSI being performed without having to request a private system status report; charging the call at the public rate upon determining that the private system is operating normally; and charging the call at the preferential rate upon determining that the private system is not operating normally. - View Dependent Claims (12, 13, 14)
