Patent number: 9591602Abstract: 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: GrantFiled: April 3, 2015Date of Patent: March 7, 2017Assignee: AT&T Mobility II LLCInventors: Michael D. Bamburak, John J. Daly, Christopher Gregory Lawrence, Michael Edward Prise, Michael Allen Raffel

Patent number: 8081973Abstract: 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: GrantFiled: March 18, 2008Date of Patent: December 20, 2011Assignee: AT&T Mobility II LLCInventors: Michael D.

Patent number: 6628935Abstract: A wireless communication device comprises a memory exceed indicator. The wireless communication device receives a message from a network. Upon receipt of the message, the device determines whether there is sufficient memory to store the message. If there is insufficient memory, the device activates a memory exceed indicator which indicates that a message is being stored in the network and that the memory of the wireless communication device contains insufficient memory to receive and store that message. If one or more messages are deleted from the memory of the device in order to make room for new messages, then a new message received from the network is stored in the memory of the device and the memory exceed indicator is deactivated.Type: GrantFiled: March 7, 2000Date of Patent: September 30, 2003Assignee: AT&T Wireless Services, Inc.Inventor: Christopher Gregory Lawrence
