US Patent:

6996396, Feb 7, 2006

Filed:

Dec 30, 1999

Appl. No.:

09/476461

Inventors:

John Lawrence Snapp - Bellevue WA, US

Assignee:

Cingular Wireless II, LLC - Atlanta GA

International Classification:

H04M 3/42

US Classification:

455417, 4554321, 455445

Abstract:

A method for use in forwarding a call intended for a GSM-roaming subscriber unit () is performed by a mobility gateway () connected between an ANSI-41 network and a GSM network. The method includes associating the roaming subscriber unit () with one of a plurality of temporary transfer-to telephone numbers homed on a mobile switching center (). The temporary transfer-to telephone number is used for an intermediate and temporary transfer of a call intended for the roaming subscriber unit () in response to some predetermined condition, such as a busy indication or expiration of time. This number is used to facilitate both the forwarding of the call to a voice mail system () and the tearing down of international long-distance connections.

International Classification:

H04Q 7/20

US Classification:

Abstract:

Methods and apparatus for estimating mobile station location include receiving reported signal strengths or other attachment indicator values from a mobile station. The reported signal strengths are compared with characteristic received signal strength values in a coverage area of a mobile network. A mobile switching center determines if a location function is requested and initiates a location estimation process by a mobile location module (MLM). The MLM receives the reported signal strength contours associated with the attachment points. Based on a comparison of the reported attachment indicator values with characteristic values, the MLM provides a mobile location estimate.

International Classification:

H04Q 7/38

US Classification:

4554141, 4554011, 4554012, 34235707, 34235708

Abstract:

Networks and methods are disclosed for providing an indication of the capability of a communication network for serving special number calls. Before a user places a special number call, the communication network determines the capability of the communication network for serving a special number call, and provides the indication of the network capability to the user. The user is thus kept aware of the quality of the special number service available to them through the communication network.

Abstract:

Methods and apparatus for estimating mobile station location include receiving reported signal strengths or other attachment indicator values from a mobile station. The reported signal strengths are compared with characteristic received signal strength values in a coverage area of a mobile network. A mobile switching center determines if a local function is requested and initiates a location estimation process by a mobile location module (MLM). The MLM receives the reported signal strength contours associated with the attachment points. Based on a comparison of the reported attachment indicator values with characteristic values, the MLM provides a mobile location estimate.

Filed:

Oct 21, 1996

Appl. No.:

8/734707

Inventors:

John Lawrence Snapp - Redmond WA

Assignee:

AT&T Wireless - Kirkland WA

International Classification:

H04B 1700
H04Q 734
H04M 124

US Classification:

455424

Abstract:

A remote automated cellular test set can be disposed in a first location and accessed via a communication network from a second location that is remote from the first location. The access to the test set can be by a technician's terminal which can remotely initiate the execution of certain commands by a first cellular phone (a test phone) in the first location. A second cellular phone is connected to the first cellular phone by an audio looping technique that permits a technician at a remote location to use the test phone at the first location as if that technician were physically located at the first location.
