According to a further feature of the invention, the controller is embedded into each of the flash chips in an array in order to further reduce overhead costs.
Abstract: A system and method for communicating accounting and billing operations information between a gateway mobile switching center (G-MSC) and a visiting mobile switching center (V-MSC) to which a call is being directed to a mobile station within a cellular telecommunications network. The method comprises the steps of: generating in the serving MSC first billing identification data for the call; transmitting the first billing identification data to the destination MSC; generating second billing identification data in the destination MSC corresponding to a call transaction that has occurred in the destination MSC; and returning the second billing identification data as related billing identification data to the serving MSC after an outcome for the call has been determined in the destination MSC. The outcome of the call is determined when a page response has been received in the V-MSC from the mobile station or alternatively, a call has been delivered by seizing a trunk from the serving MSC to the destination MSC.

Abstract: A cellular communications system including a mobile station that shifts periodically between a stand-by operating mode where communications are possible and a deep sleep operating mode wherein communications are impossible and battery power is conserved. Thus, while the mobile station is in deep sleep mode, message transmissions to the mobile station are impossible. The messages are, however, stored for later delivery, and a record of the stored, undelivered messages is maintained for future access. When the mobile station emerges from deep sleep, the maintained message record is checked, and the stored messages for the awakened mobile station are retrieved and delivered.

Abstract: The load on the communications resources of a cellular telephone system is monitored to detect instances of excess amounts of unused resource capacity. When such instances are detected, a message is transmitted to subscribers via the cellular system offering reduced charging rates for calls initiated in response to the offering message. The subscriber mobile stations are programmed to alert the subscriber to the broadcast of the offering message, after which the subscriber may initiate a reduced rate call. The mobile stations may further be programmed to automatically initiate the cellular call in response to receipt of the offering message, and to thereafter engage in the communication. Monitoring of communications resources external to the cellular system is also made, and an offering message is broadcast by the system in response to detection of excess amounts of unused external resource capacity, in response to which subscribers may initiate calls requesting reduced rate access to the resource.
