System and method for providing roaming incoming screening (RIS) in a wireless intelligent network
First Claim
1. A radio telecommunications network system covering a geographic area comprised of a plurality of service areas each of which is served by a mobile switching center (MSC) having an identification indicator (MSCID), wherein the MSCIDs are clustered into one or more groups and each group covers a corresponding region, the system including:
- a Home Location Register (HLR) which comprises;
a subscriber profile record associated with a mobile subscriber, the subscriber profile record including a service trigger for invoking a termination service; and
means for generating a call treatment instruction based on the service trigger in the subscriber profile record; and
a Service Control Point (SCP) for executing a call delivery service script in response to the call treatment instruction provided by at least the HLR, wherein the SCP includes a service profile record which comprises indication that an incoming call placed by a calling party is not to be delivered to the mobile subscriber when the mobile subscriber is located in a first region served by an MSC in a first group.

Abstract
A system and method of controlling the delivery of an incoming call in a radio telecommunications network based on the location of a roaming mobile subscriber. The radio telecommunications network includes a home network which comprises a Home Location Register (HLR) and a Service Control Point (SCP). The geographic area covered by the network comprises a plurality of regions, including the home area covered by the home network. Each of the regions comprises one or more service areas, each of which is served by a mobile switching center (MSC) having an identification indicator (MSCID). The plural MSCIDs are clustered into groups, each of which covers a corresponding region. The HLR keeps a subscriber profile which includes a termination service trigger, in addition to keeping track of the subscriber'"'"'s location. The SCP includes a service profile record which comprises one or more call delivery/termination service options. The service profile record also stores an indication for each group whether an incoming call is to be delivered to the mobile subscriber when roaming in the area or regions covered by the group. A gateway MSC interrogates the home HLR for the subscriber'"'"'s location when an incoming call is received thereat. The HLR, in turn, depending upon the termination service trigger, queries the SCP for appropriate call delivery options.

11. A radio telecommunications network system, comprising:
-
a first plurality of mobile switching centers (MSCs), each of which serves a first corresponding service area;
a second plurality of mobile switching centers (MSCs), each of which serves a second corresponding service area;
a Home Location Register (HLR) for keeping track of a mobile subscriber'"'"'s location and for storing the mobile subscriber'"'"'s service category profile, wherein the service category profile includes a service trigger; and
a Service Control Point (SCP) for executing one or more service scripts associated with the mobile subscriber responsive to the service trigger in the HLR, wherein the SCP includes a service profile record having at least one indication that when the mobile subscriber is located in the first corresponding service area, an incoming call placed by a calling party is to be delivered to the mobile subscriber, and at least one indication that when the mobile subscriber is located in the second corresponding service area, the incoming call placed by the calling party is not to be delivered to the mobile subscriber. - View Dependent Claims (12, 13, 14, 15)

16. A method of call termination with respect to a mobile subscriber in a radio telecommunications network, comprising the steps of:
-
receiving, by a mobile switching center (MSC), an incoming call from a calling party, wherein the incoming call is intended for the mobile subscriber;
interrogating, by the MSC, a Home Location Register (HLR) to determine a location of the mobile subscriber;
determining, in the HLR, whether a termination service trigger is provided for the mobile subscriber;
if so, determining, in the SCP, whether the incoming call is to be delivered to the mobile subscriber via a call delivery, based on the location of the mobile subscriber; and
selectively delivering the call to the mobile subscriber. - View Dependent Claims (17, 18, 19, 20, 21)
determining whether the calling party'"'"'s telephone number matches a selected telephone number for which the call delivery is allowed; and
responsive to the determining step, selectively delivering the call to the mobile subscriber.
