First Claim
1. A method for providing a calling party number to a called party, said calling party number being associated with a roaming mobile station in a visited public land mobile network (V-PLMN) subscribing to a home public land mobile network (H-PLMN), said method comprising the steps of:
- receiving, at said V-PLMN, a request from said roaming mobile station to establish a call to said called party;
transmitting, from said V-PLMN, said calling party number associated with said roaming mobile station to a service control point (SCP);
storing said calling party number at said service control point (SCP);
routing the call without the calling party number from the V-PLMN to a switching point serving the called party;
querying the SCP, by the serving switching point, for the calling party number;
transmitting said calling party number from said SCP to the switching point serving said called party in response to said querying step;
delivering the call by the serving switching point to the called party; and

Abstract
A system, method, and apparatus are provided for sending a calling party number for a roaming mobile station to a called party. The roaming mobile station subscriber dials an abbreviated number, corresponding to a full directory phone number, which is received by a visited public land mobile network (V-PLMN) . The V-PLMN queries a service control point (SCP) to determine routing instructions corresponding to the abbreviated number. During the query, the SCP stores the calling party number in a register. The SCP transmits the routing instructions appended with an index and an identification number for the SCP. The V-PLMN uses the route instructions to route the call generated by the mobile station to a switching point serving the called party. The switching point then uses the index to retrieve the stored called party number from the SCP.
