Anonymous call blocking in wireless networks
First Claim
1. A wireless network for providing anonymous call blocking, the wireless network comprising:
- a Mobile Switching Center (MSC) system that receives a call from a calling party to a called party, and generates a call setup message for the call; and
a Home Location Register (HLR) system that receives the call setup message from the MSC system, determines if the called party subscribes to anonymous call blocking, determines if the call setup message includes caller ID information, and generates a call blocking message for blocking the call responsive to determining that the called party subscribes to anonymous call blocking and responsive to determining that the call setup message does not include the caller ID information.

Abstract
Wireless networks and methods are disclosed that provide for anonymous call blocking in wireless networks. A wireless network of the invention includes an MSC system and an HLR system. When a calling party initiates a call to a called party, the MSC system receives the call and generates a call setup message for the call. The call is anonymous, so the call setup message does not include caller ID information for the calling party. The MSC system receiving the call transmits the call setup message to the HLR system. The HLR system determines if the call setup message includes caller ID information, and determines if the called party subscribes to anonymous call blocking. Responsive to determining that there is no caller ID information in the call setup message and that the called party subscribes to anonymous call blocking, the HLR system instructs the MSC system to block the call.

7. A method of operating a wireless network for providing anonymous call blocking, the wireless network comprising a Mobile Switching Center (MSC) system and a Home Location Register (HLR) system, the method comprising:
-
receiving a call from a calling party to a called party in the MSC system; generating a call setup message for the call in the MSC system and transmitting the call setup message to the HLR system; determining if the called party subscribes to anonymous call blocking in the HLR system; determining if the call setup message includes caller ID information in the HLR system; and generating a call blocking message for blocking the call responsive to determining that the called party subscribes to anonymous call blocking and responsive to determining that the call setup message does not include the caller ID information. - View Dependent Claims (8, 9, 10, 11, 12)

13. A wireless network for providing anonymous call blocking, the wireless network comprising:
-
an originating Mobile Switching Center (O-MSC) that serves a calling party; a serving Mobile Switching Center (S-MSC) that serves a called party; and a Home Location Register (HLR); the S-MSC receives an anonymous call blocking instruction from the called party, and stores an anonymous call blocking indicator in the HLR; the O-MSC receives a call from the calling party to the called party and transmits a call setup message to the HLR; the HLR determines if the call setup message includes caller ID information, determines if the called party subscribes to anonymous call blocking based on the anonymous call blocking indicator, and generates a call blocking message for blocking the call responsive to determining that the called party subscribes to anonymous call blocking and responsive to determining that the call setup message does not include the caller ID information. - View Dependent Claims (14, 15, 16)
