Abstract: An arrangement where a transmitter has a plurality of transmitting antennas that concurrently transmit the same symbol, and where the signal delivered to each transmitting antenna is weighted by a factor that is related to the channel transmission coefficients found between the transmitting antenna and receiving antennas.

Abstract: Methods and systems are provide for processing prepaid calling time to a subscriber by determining an identity of a subscriber of prepaid calling time upon origination of a call to which a subscriber of prepaid calling time is to be a party; determining an amount of prepaid calling time available to the subscriber; allowing a call to which the subscriber is to be a party to be connected if prepaid calling time is available to the subscriber; and deducting calling time from the available prepaid calling time of the subscriber as the connected call proceeds. The method also provides for purchasing pre-paid calling time by electronically transferring funds from an account of the subscriber to an account of a pre-paid call time provider, the amount of funds transferred equal to the dollar amount of pre-paid calling time to be credited to the subscriber; and crediting to the subscriber an amount of pre-paid calling time corresponding to the dollar amount of the transferred funds.

Abstract: The present invention is a system and method of providing the information necessary for geographically-based mobile services by translating public geographic information to corresponding mobile network structure. When an indication of a geographic area is received, the indication is translated to an indication of a portion of the mobile network corresponding to the geographic area and an indication of the service is transmitted to the indicated portion of the mobile network. In a preferred embodiment, a broadcast message is transmitted over a mobile network to a plurality of mobile stations within a geographic area. When the system receives a message to be broadcast and an indication of the geographic area of the broadcast, the indication of the geographic area is translated to an indication of a portion of the mobile network corresponding to the geographic area. The message is then transmitted to the indicated portion of the mobile network.

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.
