  • Patent number: 6122523
    Abstract: 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).

  • Patent number: 6021335
    Abstract: 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.

  • Patent number: 5926763
    Abstract: A cellular communication system (10) includes any number of land stations (12), each of which controls a cell (14). When channels are assigned to cells (14), a figure of merit which predicts potential voice quality, such as C/I, is determined (34) for each channel/cell assignment. The assigned channels and associated figures of merit are distributed to corresponding land stations (14) to make channel-to-cell assignments. When a call arises in a cell (14) a channel is selected for assignment to the call. The channel is selected from channels assigned during the channel-to-cell assignment phase. A channel assignment algorithm (68) ensures that potentially lower quality channels (20) are the least used channels at the cell (14). When potentially lower quality channels (20) are assigned to calls, the calls are handed off to potentially higher quality channels (18) as soon as potentially higher quality channels (18) become available.

  • Patent number: 5887259
    Abstract: 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.

  • Patent number: 5774805
    Abstract: A multi-mode communication network (12) accommodates piloted cellular operation and pilotless cordless operation using a multi-mode handset (18). A common pool of channels (28) serves cellular and cordless operations. At least some channels from a cordless subset (32) of the pool of channels (28) are unused in cellular operations regardless of location. The handset (18) monitors forward portions of all cordless subset channels when the handset (18) is within the coverage area (16) of its cordless base station (22). Unused channels are indicated on a dormant channel list (70), which is passed to the handset's cordless base station (22) when the handset (18) registers for cordless operation. The cordless base station (22) makes an active channel list (62) based upon the dormant channel list (70). Cordless operation messages transmitted from either a handset (18) or cordless base station (22) use a channel selected from the active channel list (62).

  • Patent number: 5031204
    Abstract: A method and apparatus for an authorized user of a cellular mobile radiotelephone to easily obtain data and performance evaluation of the telephone, such as the electronic serial number (ESN), the mobile telephone number (MID), and transmitted audio information that permits evaluation of the voice modulation performance of the telephone. By calling a dedicated telephone number, an authorized operator, such as a cellular agent, can contact a computer with voice response capability, which is associated with the electronic mobile exchange (cellular switch). The computer then transmits to the agent a voice prompt requesting a password. Upon correct entry of the password, the computer initiates a trunk trace of the incoming call. The trunk trace identifies the ESN and MID for the telephone used to make the call. The computer reports that data to the calling party, via the cellular network.
