Inbound roamer call control system
First Claim
1. A system for implementing call control services for an inbound roamer, the system comprising:
- a control node to implement the call control services in response to an initiation request;
a visited public land mobile network (VPLMN) value added service (VAS) node to send a terminating customized applications for mobile network enhanced logic subscription information (T-CSI) for a called number in response to a routing request for the called number, wherein the T-CSI contains an address pointing to the control node; and
a switching center to send the routing request for the called number and the initiation request, wherein the called number is present in a call received from the inbound roamer and the called number satisfies pre-determined criteria.
