Definitions
- the telecomputer has an electronic microprocessor circuit board that directly interfaces a numeric or alphanumeric paging radio receiver system having a port for downloading data and which is removable or non-removable from a portable computer that also internally contains a cellular telephone.
- the information received by the telecomputer can be stored on an electromagnetic storage medium such as tape, drum, floppy disc, hard disk drive, optical laser disc or other retention medium.
- the information may also be stored in volatile or non-volatile memory elements.
- the telecomputer can also be programmed to verify for the central paging mainframe computer the receipt of a high priority numeric or alphanumeric pager message. The device then shuts off all other systems of the telecomputer except the paging function while alerting the user by appropriate external audible or visual signal as to what is occurring.
- Figure 1 is a block diagram illustrating the telecomputer device used in the present invention.
- CPU 12 central processing unit
- CPU 12 may also integrally include RAM and/or ROM storage devices.
- a task scheduler 10 also is connected to CPU 12. As further described below, task scheduler 10 helps CPU 12 supervise the flow of information between CPU 12 and other elements of the telecomputer of Applicants' invention.
- a facility known as an "interrupt” allows the execution of the CPU to be interrupted periodically based on requests for service from internal or external devices or based on the passage of a certain amount of time.
- an interrupt occurs and depending on its priority with respect to other interrupts and the task currently being performed by the CPU, the CPU stores information about the task it was performing when the interrupt occurred and then executes another task determined by the nature of the interrupt. The stored information allows the CPU to resume execution of the task which was interrupted once it has finished performing the task required by the interrupt. The CPU may also execute other tasks required by other higher priority interrupts before returning to the original task.
- Task scheduler 10 performs this function. The operation of task scheduler 10 is itself supervised by CPU 12.
- the telecomputer of Applicants' invention is powered by AC power 15 when available or by battery 16. Power may also be provided by solar power 17 which also can be used to maintain battery 16 in a charged state.
- the telecomputer also includes a satellite transmitter/receiver 14 for sending and receiving radio signals from a satellite as discussed below.
- Data distribution center 20 may be formed of a main frame computer and include many of the elements illustrated in Figure 1 with respect to the telecomputer of Applicants' invention.
- data distribution center 20 Upon receiving the pager induced looped call from the telecomputer' s internal cellular telephone 9, data distribution center 20 automatically transfers back to the telecomputer' s data storage section (mass storage devices 11, e.g.), any electronic data messages such as E-MAIL, file achieves, group level-3 facsimiles, telex, telegram or when attended, voice mail or two-way voice calls that are bing held in data distribution center 20.
- mass storage devices 11 mass storage devices 11, e.g.
- any electronic data messages such as E-MAIL, file achieves, group level-3 facsimiles, telex, telegram or when attended, voice mail or two-way voice calls that are bing held in data distribution center 20.
- telecomputer 30 may also be programmed to verify for data distribution center 20 the receipt of a high priority numeric or alphanumeric pager message. Telecomputer 30 may then shut off all other systems of the telecomputer except the paging function while alerting the user by appropriate external audible or visual signal as to what is occurring.
- a user of telecomputer 30 may originate communication information in the form of a voice telephone signal, for example, for transmission through the system to a distant telephone.
- Such communication information is transferred to data distribution center 20 via switched telephone network 23 using modem 5 shown in Figure 1 or via cellular telephone transmission facility 27 using cellular telephone 9 shown in Figure 1.
- the communication information includes distribution information which is used by data distribution center 20 to route the communication information to the recipient in the most efficient manner. In the case of a voice or facsimile telephone number. If the destination telephone number is connected to the switched telephone network 23, data distribution center routes the communication information to the telephone network via communications path 24 for transfer to the destination telephone. Data distribution center 20 may hold the communication information for later transfer to the recipient.
- second telecomputer 30 If second telecomputer 30 is located a great distance from first telecomputer 30, the communication information maybe routed through up/down link 21 for transfer via satellite to satellite transmitter/receiver 14 shown in Figure 1. Telecomputer 30 also may use transmitter/receiver 14 to transmit the communications information directly to the satellite for down linking to up/down link 21 and transfer to data distribution center 20 for routing to the recipient.
