Patent number: 6735432Abstract: A mobile station communicates with both a cellular network, by which it is assigned a mobile identification number, and to a cordless cellular base station utilizing the same cellular frequency range and communications protocol. The cordless cellular base station is preferably connected to a public switched telephone network and is assigned a landline number. The cordless cellular base station acts as a conduit between the mobile station and the public switched telephone network. When the mobile station comes within range of a cordless cellular base station, it deregisters automatically from the cellular network and register with the cordless cellular base station. Once the mobile station is communicating with the cordless cellular base station, the cordless cellular base station communicates with the cellular network to instruct the cellular network to route all calls for mobile identification number to the cordless cellular base station's landline number.Type: GrantFiled: November 4, 1998Date of Patent: May 11, 2004Assignee: AT&T Wireless Services, Inc.Inventors: Keith Jarett, Roland E. Williams, Michael A. Raffel, Roderick Nelson, Ileana A. Leuca, Tony S. Lee, Christopher G. Lawrence, Masud Kibria, David R. Glass, Michael D. Bamburak

Publication number: 20020137466Abstract: A communication device locates a wireless service provider in a multi-service provider environment using a frequency band search schedule. The frequency band search schedule has a first or home band and a several other frequency bands in a predetermined order. The order of the frequency bands may be programmed by the user or by a home service provider over the air. The communication device searches for an acceptable service provider by examining the home band and then the other bands listed in the frequency band search schedule. The bands are examined in the order specified by the frequency band search schedule. An acceptable service provider is identified by comparing the identity of a service provider specified by an identifier received from a band being examined with a list of acceptable service providers.Type: ApplicationFiled: May 28, 2002Publication date: September 26, 2002Applicant: AT&T WIRELESS SERVICES, INC.Inventors: Michael D.

Publication number: 20020102955Abstract: A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency band search schedule. Initially, the communications device registers with a less preferred service provider in a first frequency band. While remaining registered with the less preferred service provider, the device examines several frequency bands in the order specified by the frequency band search schedule. A frequency band is examined by dividing the frequency band into many sub-bands, and by locating the strongest signal above a threshold within the sub-band being examined. The examination continues until a second frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider. The category of service provider may be identified and displayed on the communication device.Type: ApplicationFiled: March 19, 2002Publication date: August 1, 2002Applicant: AT&T WIRELESS SERVICES, INC.Inventors: Michael D.

Publication number: 20020098848Abstract: A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency or frequency band search schedule. Initially, the communication device registers with a less preferred service provider in a first frequency. While remaining registered with the less preferred service provider, the device examines several frequencies in the order specified by the frequency search schedule. The device determines whether the last frequency used by the communication device has a more preferred service provider. If the last frequency used does not have a more preferred service provider, the device examines each of the plurality of frequencies in the predetermined order in the search schedule. The examination continues until another frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider.Type: ApplicationFiled: March 19, 2002Publication date: July 25, 2002Applicant: AT&T WIRELESS SERVICES, INC.Inventors: Michael D.

Patent number: 5905955Abstract: A communication device locates a wireless service provider in a multi-service provider environment by tuning to a first frequency band and receiving a geographic identifier from the service provider operating in the first frequency band. The received geographic identifier is compared to a listing of stored geographic identifiers in order to attempt to locate a matching stored geographic identifier. Each of the stored geographic identifiers are associated with a desirable frequency band having a desirable service provider. If comparing the received geographic identifier with the matching stored geographic identifiers does not produce a match, frequency bands are examined until a second frequency band having a desirable service provider is located. The listing of stored geographic identifiers is then updated so that the second frequency band is associated with the received geographic identifier.Type: GrantFiled: December 12, 1995Date of Patent: May 18, 1999Assignee: AT&T Wireless Services Inc.Inventors: Michael D.
