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.
