Patent number: 5887259Abstract: A multiple mode, personal, wireless communications system exists within a radiotelephone network serving general customers and provides additional services to a select group of customers. The system uses handsets (32) which automatically switch between a standard cellular radiotelephone mode of operation (1901) and an enhanced cordless mode (1420) when the handsets (32) are within range of pico cells (26) that are interconnected to the public switched telephone network (20). Each pico cell is controlled via a framework of overlay cells (10b) that operates independently of the radiotelephone network and uses a unique control protocol on a small number of reserved cellular channels. Each pico cell consists of a spectrally dynamic, non-capturing, frequency agile, multi-purpose base station (26) provided at customer-selected locations to cooperate with the overlay cell framework. Each pico cell is capable of supporting multiple handsets (32) and using low power operation that achieves limited coverage.Type: GrantFiled: June 22, 1994Date of Patent: March 23, 1999Assignee: GTE Mobile Communications Service CorporationInventors: Robert G.

Patent number: 5878339Abstract: A cellular radiotelephone system (10) includes mobile stations (28) which may be remotely programmed from a customer activation system (12) to effect activation and other programming needs. Mobile stations (28) are manufactured in a blank form that causes them to operate only in an inactive state. During activation, information describing the mobile station's electronic serial number (ESN) is collected along with area of use information. A mobile identification number (MIN) is assigned in response to the area of use information. A page message is directed to the mobile station operating in its inactive state, but the page message references the mobile station's ESN. While inactive, the mobile station (28) detects pages directed to its ESN. A remote programming session is then performed wherein digital user-specific programming data, including the newly assigned MIN, are transferred to the mobile station (28) over a voice channel using a control channel protocol (80).Type: GrantFiled: February 6, 1998Date of Patent: March 2, 1999Assignee: GTE Mobile Communications Service CorporationInventors: Robert G.

Patent number: 5535260Abstract: A radiotelephone (10) simulates the call origination process performed by land-line telephones. Dial tone is generated (78) in response to an off-hook condition and removed when a first digit (54) is dialed. A timer process (84, 110) and a number analysis process (100) simultaneously evaluate dialed digits to detect the completion of dialing. The number analysis process (100) identifies seven, ten, and eleven digit, and indeterminate length phone number formats (64, 66, 52, 68). The ten digit format is recognized in response to remotely programmed (42) connected NPA codes. For most calls, the number analysis process (100) instantly detects a phone number's final digit (62). In a few cases the timer process (84, 110) detects the final digit through the absence of dialing activity for a predetermined duration. When the final digit (62) is detected, an origination message is transmitted to a cellular network.Type: GrantFiled: September 29, 1994Date of Patent: July 9, 1996Assignee: GTE Mobile Communictions ServicesInventors: Robert G.

Patent number: 5159625Abstract: A remotely programmable cellular mobile radiotelephone (CMR 12) is configured to select (1300) a cellular system (14-16) with which to communicate while roaming. The CMR (12) utilizes a default system selection process. The system selected using this default process is identified (1302) and a SID list (1402) is checked to see if the system identification number (SID) of the identified system is on the list (1402). The SID list (1402) is maintained in a current state through remote programming sessions (1500). When the default system's SID is not on the list (1402), CMR (12) operation continues normally. When the default system's SID is on the SID list (1402), the default system selection process is replaced with an alternate system selection process (1316-1322). If a new system selected by the alternate process is not available or if a new system is available but listed on the SID list (1402), then the CMR (12) simulates a no service mode of operation (1332-1338).Type: GrantFiled: October 24, 1990Date of Patent: October 27, 1992Assignee: GTE Mobile Communications Service Corp.Inventor: Robert G.
