Method and system for transferring subscriber information in a radio telecommunications network
First Claim
1. In a radio telecommunication system having a gateway mobile switching center (G-MSC), a home location register (HLR), and a service control point (SCP), a method of conveying required information about a subscriber to said SCP for implementing a requested intelligent network (IN) service in a radio telecommunications network, said method comprising the steps of:
- sending a first signaling message requesting a location of said subscriber from said G-MSC to said HLR;
recognizing that said subscriber has said IN service by said HLR;
communicating an indication that said subscriber has said IN service from said HLR to said G-MSC;
sending a second signaling message from said G-MSC to said SCP informing said SCP of said requested IN service;
transmitting a data request message from said SCP to said HLR requesting said required subscriber information; and
sending a data message from said HLR to said SCP containing said required subscriber information.

Abstract
A method and system for transferring subscriber information required for implementing an intelligent network (IN) service in a radio telecommunications network. The method begins by a G-MSC sending a signaling message requesting a location of the subscriber to a HLR. The HLR then recognizes that the subscriber has requested an IN service. Next, the HLR sends an indication that the subscriber has the requested IN service to the G-MSC. The next step includes sending a signaling message from the G-MSC to a service control point (SCP) identifying the IN service requested. Subsequently, the SCP requests from the HLR the subscriber information required for implementing the requested IN service. The HLR then sends a data message containing the requested subscriber information to the SCP. If the HLR does not have the requested information, but the information is available in a visited mobile switching center (V-MSC) where the subscriber is operating, the HLR requests and obtains the information from the V-MSC, and then forwards the information to the SCP.

11. A radio telecommunication system that obtains and utilizes subscriber information stored in a home location register (HLR) to implement a requested intelligent network (IN) service, said system comprising:
-
a gateway mobile switching center (G-MSC) for receiving an incoming call for a subscriber, said incoming call requesting said IN service; a service control point (SCP) for implementing said requested IN service in said radio telecommunication system, said SCP including means for identifying subscriber information stored in said HLR required to implement said requested IN service; means for notifying said SCP of the requested IN service; means for sending a request for said required subscriber information from said SCP to said HLR; and means for sending said requested required subscriber information from said HLR to said SCP in response to a request from said SCP. - View Dependent Claims (12, 13, 14, 15, 16, 17)
