Description

Subscriber Address Allocation Method in Two-Way Radio Calling System

The present invention relates to a two-way radio pager, and more particularly, to a method for assigning a subscriber address and a call number of a two-way radio pager.

In general, a wireless paging system stores necessary information in a POCSAG code and modulates the frequency to a corresponding page and transmits the information to a wireless paging machine. The radio pager receives the corresponding frequency signal if it matches the channel frequency, decodes the bread code at the received frequency, and if the address data of the bread code matches the address data of the wireless pager, information from the bread code. Read data

As such, the pager has an address which is a unique ID. The address is assigned to the manufacturer by the wireless paging service provider, and the manufacturer inputs and assigns the address assigned to the internal memory of the wireless paging machine.

In inputting the address of the conventional pager as described above, a case in which an address input is incorrect in a manufacturing process of the pager occurs. In other words, the address requested by the wireless paging service provider is 1234567. In fact, an incorrect address is generated in the memory of the pager, such as 1234568. In addition, there is a limit to the number of subscribers per channel in the burst code format of a conventional pager. Assuming that a typical 100,000 subscribers can be accommodated, the wireless paging service provider notifies the manufacturer of 100,000 addresses and receives the pager with the assigned address. In this case, if the pager allocated to the wireless pager is not sold because the address is not sold, a problem arises that it is difficult to process the address assigned to the pager.

It is therefore an object of the present invention to provide a method for assigning an address of a two-way radio pager.

Another object of the present invention is to provide a method for allocating a subscriber call number in a two-way wireless pager.

In order to achieve the above objects, the present invention provides an address and a call number that can be allocated in response to the assignment request message in a radio calling system when the device transmits an address and call number assignment request message when power is supplied from the bidirectional pager. And the wireless pager stores the allocated address and call number in a memory.

1 and 2, the overall operation of a two-way pager according to an embodiment of the present invention will be described. The controller 210 controls the call service function of the two-way wireless pager to which the present invention is applied. The memory 220 stores information of the pager and stores a program for assigning an address and a call number according to an embodiment of the present invention. In addition, the memory 220 stores an address and a call number allocated from the wireless call system according to an embodiment of the present invention. The key input unit 230 includes keys for generating various control signals of the pager. Examples of the keys may include a power key for turning on / off a power of a pager, a mode key for implementing various operations and functions, and a lead key for displaying a received message. The key input unit 230 generates key data for mode change by simultaneously pressing the mode key and the lead key. After the mode change is set, the lead key and the mode key perform a function of selecting contents to be changed and inputting and storing change data. The key input unit 230 generates key data corresponding to a key input according to a user's operation and applies the generated key data to the controller 210. The frequency synthesizer 240 synthesizes a predetermined frequency under the control of the controller 210 and applies it to the RF unit 250. That is, the frequency synthesizer 240 designates a channel of the RF unit 240 according to the channel data output from the controller 210. The RF unit 250 is a channel designated by the frequency synthesizer 240, amplifies the weak RF signal of the specified channel received through the antenna, and converts the amplified signal to the original signal band and demodulates the demodulated signal. Waveform is output by digital data. In addition, the RF unit 250 transmits a message requesting assignment of an address and a call number of the pager according to an embodiment of the present invention to the wireless call system. The decoder 260 decodes and outputs the digitally coded data output from the RF unit 250. That is, the received coded data (usually BCH coded data) is decoded into original data, and the preamble data, the word sink and its own frame data are detected and output from the form of the bread code. The display unit 270 may be implemented as an LCD, and under various control, the display unit 270 displays various situations and received messages generated during a wireless call service. The alarm unit 280 includes a means for generating an alarm sound, a vibrator for generating a vibration signal, and the like, and generates an alarm signal when a message is received under the control of the controller 210.

3 is a diagram illustrating a process of allocating a subscriber address and a call number in a two-way wireless paging system according to an embodiment of the present invention.

A method of allocating a subscriber address and a call number in a two-way wireless paging system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. In step 300, the controller 210 of the pager 130 determines whether the power of the bidirectional pager is turned on. When the power is turned on, in step 310, the controller 210 transmits a message for requesting allocation of an address and a call number to the wireless call system 120 through the RF unit 250.

In step 320, the wireless paging system 120 determines whether the received message is a message for requesting assignment of an address and a call number to the wireless paging machine 130. If the received message is not a message for requesting allocation of an address and a call number to the pager 130, the wireless call system 120 performs an operation corresponding to the received message in step 330. In contrast, when the received message is a message for requesting allocation of an address and a call number to the pager 130, the wireless call system 120 searches for an address and a call number to be allocated through the address allocation system 110 in step 340. In step 350, the wireless call system 120 receives an address and a call number that can be allocated from the address assignment system 110 and transmits the address and call number data to the wireless pager 130.

In step 360, the controller 210 of the pager 130 determines whether the message received from the wireless call system 120 through the RF unit 250 is an input message for allocating an address and a call number of the pager 130. If the message received from the wireless paging system 120 is not an input message for allocating an address and a call number of the wireless pager 130, the control unit 210 of the wireless pager 130 performs a control operation corresponding to the received message in step 370. In contrast, when the message received from the wireless paging system 120 is an input message for allocating an address and a call number of the wireless pager 130, the control unit 210 of the wireless pager 130 stores the allocated address and call number in the memory 220 in step 380. do. In step 390, the controller 210 of the pager 130 initializes the pager 130 to receive data at the stored address and call number.

As described above, the present invention has an advantage of efficiently allocating an address and a call number of a pager in a two-way wireless paging system. In addition, the present invention may require the assignment of an address and a call number when an address and a call number are incorrectly input in the bidirectional pager.
