Filed:

Dec 21, 2000

Appl. No.:

09/742272

Inventors:

J. Carl Bedingfield - Lilburn GA, US
Annie Nguyen - Kirkland WA, US

Assignee:

BellSouth Intellectual Property Corporation - Wilmington DE

International Classification:

H04M001/56

US Classification:

37920702, 37914206

Abstract:

A method and system are disclosed for preserving caller privacy in an advanced intelligent network comprising a service switching point and a second service switching point. The service switching point is adapted to suspend calls directed to a predefined number and forward signaling information associated with the call to the service control point. The service control point is adapted to alter the signaling information if a privacy restriction indicator in the signaling information is activated and to forward the altered signaling information to the service switching point. The method comprises the following steps: forwarding information identifying a calling party and any privacy restrictions on the calling party information from the service switching point to the service control point; and if the privacy restrictions indicate that the calling party information should not be delivered to the called party, altering the calling party information and forwarding the altered information to the service switching point.

International Classification:

H04W 4/00

US Classification:

455433, 37922113

Abstract:

A mobility management analysis architecture for call management. Systems and methods are provided for routing of a landline-mobile and mobile-mobile call using a switching network (landline or mobile originating) to serve effectively as the “GMSC/tandem” switching layer for the mobile network, as well as for mobile-mobile calls using an originating switch. When a landline switch issues an local number portability (LNP) query, the response to the query can be intercepted by a preliminary mobility management platform that determines a location routing number (LRN) for a visited mobile switching center (V-MSC) to which a destination mobile handset is currently attached. The LRN for that V-MSC is returned in the LNP response to the switch, which then routes the call to the serving V-MSC based on the LRN. The V-MSC then performs the GMSC (gateway mobile switching center) functionality, for example, for that particular call.
