The paging equipment that is shown in Fig. 1 comprises receiving circuit 1, and it is fit to and the radio signal that receives from antenna 2, the radio signal that demodulate reception arrives, and a digital output signal corresponding to demodulated radio signal offers central processing circuit 3.Treatment circuit 3 is connected to input unit 4, output device 5 and storage device 6.Storage device comprises to be called out and evaluator memory 7, transparent data memory 8, interpretive program memory 9 and variable application memory 10.
With reference to the flow chart of Fig. 2, express in the operation of the paging equipment of Fig. 1.Can be considered as call signal to the digital output signal of receiving circuit 1, or be called for short and call out, it comprises address and message or the data (frame 21) that branch is tasked one or more paging equipments.Treatment circuit 3 is at first handled the calling that receives according to the originated call handling procedure that is stored in calling and the evaluator memory 7.In memory (for example the transparent data memory 8), storing and dividing an one or more independent address and/or a group address of tasking paging equipment.If, for the calling that receives according to the originated call handling procedure, treatment circuit 3 detects an address in the calling that receives, this address is identical with the address in being stored in memory 8, then the calling that receives is considered as the desirable calling of this paging equipment (frame 22).If do not receive calling, perhaps do not receive and have correct address the calling of (that is, dividing the address of tasking paging equipment), then Waiting for Call (being back to frame 21).
Detect correct address (frame 22) afterwards in the calling (frame 21) that treatment circuit 3 is receiving, treatment circuit detects with the program that is stored in the memory 7 whether the data that occur are transparent data (frame 23) in calling.Transparent data be interpreted as need not do any processing and/or in fact paging equipment be set to the significant data of another state (for example alarm status), but it can not change the operation by the paging equipment of the procedure stipulation in memory 7.If the data that receive are transparent datas, then treatment circuit 3 is stored in (frame 24) in the transparent data memory 8 to it.Depend on user by paging equipment by the order that input unit 4 provides, the transparent data that receives can be immediately or is not presented to the user with tangibly mode (passing through vibrating device) and/or audible mode and/or visual means immediately.
Except whether treatment circuit 3 authentication datas are the transparent data (frame 23), the explanation that provides above can be used for general known paging equipment.
According to the present invention, except that identification function (frame 23) and be stored in the evaluator in the memory 7, paging equipment also comprises interpretive program memory 9 and variable application memory 10.If treatment circuit 3 determines that the data that receive are not transparent data (frames 23), then treatment circuit 3 is this storage (frame 25) in variable application memory 10.Be stored in the data represented one or more application programs that receive by one or more callings that comprise opaque data in the memory 10.Interpretive program memory 9 comprises interpretive program (" translater " (interpreter)), and it is suitable for an instruction and data that is stored in the Any Application in the memory 10 is translated into the form that is suitable for treatment circuit 3.After having handled a calling, no matter whether it comprises transparent data, the operation of paging equipment (the especially operation of treatment circuit 3) is not only also carried out (frame 26) according to the variable application program that is stored in the memory 10 according to the program that is stored in the memory 7.The data that variable application program needs can be stored in memory 10 and/or the transparent data memory 8.
Depend on by the order that previously has been stored in the memory 10 or some application programs or has provided by input unit, can start the application program that is stored in the memory 10 by the user.
Because memory 10 can comprise one or more application programs (they can be changed repeatedly by one or more callings, substitute or replenish), can easily make according to paging equipment of the present invention to be suitable for operating according to a plurality of application.Described application can be special for one or more individualities and/or operand.Analysis and the graphic representation (such as price quoted security and process measurement value) and the stopwatch of the figure that the example of application program is games (such as personal electric " pet toy " (cuddlytoy) (" Tamagotchi ")), receive as transparent data.Some program that is coupled to the call address of device is only just sending by payment.For example, behind pet toy " death ", application program can oneself quit work, and the user at first is necessary for desired new " toy " payment.Application program (it can be less) by sending again thereafter can restart games.In this example, the operator of transmitter even can be satisfied with the standard income that brings by call establishment, this calling can excite the use of these programs, therefore, produces income from the calling of connecting.Use the single actual device of paging equipment of the present invention, just can realize these application and other application.As a result, can significantly save the cost of production, storage and commercial value aspect.
Can adopt known method to send from a center and call out, this center can be connected to a data input unit by telephone connection, and this device can be telephone device or computer.For using, therefore need when finishing, emission not change, as long as data input device is suitable for importing the data that are identified as opaque data to it according to paging equipment of the present invention.In order in existing systems, to use paging equipment, can stipulate, if treatment circuit 3 call out data in identify one of data with ad hoc structure or multinomial (combination of value or value), then actual call and/or follow-up calling comprise opaque data (vice versa).
For especially at public's calling system (" wide area paging ", WAP) prevent in that unauthorized individual from changing the content of variable application memory 10, the program that is stored in calling and the evaluator memory 7 preferably includes such function, treatment circuit 3 uses this function to check the opaque data that receiving, and sees whether or to receive correct fetcher code (frame 27).Can receive fetcher code simultaneously as the transparent data of formerly calling out in calling that comprises opaque data or conduct in (or affirmation is thereafter called out).For example use the RSA cryptographic algorithms can be to fetcher code and the opaque data encryption that is associated.Even encrypt, after data were decrypted, it is identifiable one by one that fetcher code needs not to be, and can be hidden in the fact that data decryption must obtain accessible data.In addition, also can comprise fetcher code separately through decrypted data, this fetcher code is for example stipulated will be by the sender of paging equipment confirmation.Being stored in call processing program in the memory 7 or some is stored in variable application program in the memory 10 constantly and goes for so intrinsic or additional fetcher code changed and check step.
Can use diverse ways design stores device 6.Memory 7 and 9 for example is read-only memory (ROM), and memory 8 for example is volatile memory (RAM), and memory 10 for example is non-volatile recordable memory (EPROM or a flash memory).Storage device 6 also can comprise single Nonvolatile rewriteable memory.
