TECHNICAL FIELD The present invention relates to a wireless paging system, and more particularly, to a method of switching a call to a pager.

Typically, a radio paging system provides additional services that can divert a call to a particular pager, i.e., a radio page receiver, to another pager. This supplementary service is called a call transfer service. This call transfer service allows a pager subscriber to receive a call message for itself to another pager.

However, call transfer service has been provided only to internal calls within one radio calling system. That is, only the call transfer between pager subscribers subscribed to the same wireless paging system was possible.

Therefore, even if the same model in the same region as well as other regions, there was a problem that you can not transfer to the pager subscriber of the other paging system. Accordingly, call transfer service is virtually not used in the wireless paging system.

On the other hand, in the case of the wide area service, not only the wide area pager must be provided but also the subscriber station is located in an overlapping area, so the area selection function of the wide area pager is difficult to operate normally.

Accordingly, an object of the present invention is to provide a call transfer method for a whole area which can transfer a call between another area and another wireless calling system in the same area.

Another object of the present invention is to provide a whole area call transfer method capable of transferring a call between another region and another wireless calling system in the same region using a local pager for each region.

Still another object of the present invention is to provide a method for transferring a whole area, which can prevent a decrease in reception rate for the whole area.

In order to achieve the above objects, the present invention transfers a call to a pager subscribed to another wireless paging system. If there is a call for a registered pager, the call transfer number and a message are transferred through the NO.7 wide area network. The pager is subscribed to the wireless paging system characterized in that the pager is transferred wirelessly.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description and in the accompanying drawings to provide a more general understanding of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. In addition, detailed descriptions of well-known functions and configurations that may obscure the gist of the present invention will be omitted.

FIG. 1 is a block diagram of a wide area network wireless paging system according to an embodiment of the present invention, showing that the wireless area paging systems 102A to 102C of the whole area are connected to each other through the NO.7 wide area network 106. FIG. It is. Although only three radio calling systems 102A-102C are shown in FIG. 1 for convenience, in practice, all radio calling systems throughout the region are equally connected to each other via the NO.7 wide area network 106. In the example of FIG. 1, two radio calling systems 102A and 102B are connected to one Public Switching Telephone Network (PSTN) 100A as a radio calling system in the same area, and the other radio calling system 102C. Is connected to another PSTN 100B as another radio calling system in a different area than the radio calling systems 102A and 102B. In addition, each of the radio calling systems 102A-102C is correspondingly connected one by one with transmitters 104A-104C at the site.

Each of the radio calling systems 102A to 102C is implemented to perform a call transfer function according to the present invention, for example, to the existing Korean radio calling system TDX-PS. The relay line matching unit 108 and the number translator ( 110), a paging terminal (hereinafter referred to as PT), a call transfer / wide area processing unit 114, a data processing unit 116, and a VMS (Voice Mailing System) matching unit 118. The relay line matching unit 108 introduces a radio call into the radio call system from the PSTN to which the corresponding radio call system of the PSTNs 100A and 100B is connected. The data processing unit 116 is connected to the call transfer / wide area processing unit 114, and is connected to a signal link of the NO.7 wide area network 106 to transfer packet data to the data processing unit 116 and the NO of another radio calling system. .7 send and receive using protocol. The number translation unit 110 translates the incoming pager number or the incoming pager number received from another radio calling system through the data processing unit 116 according to the incoming call from the relay line matching unit 108 to convert the corresponding PT ( Call 112). The majority PT 112 connects the ringing tone to the calling subscriber, receives the message, and makes a wireless call to the transfer or incoming pager. The VMS matching unit 118 provides a VMS service.

In the wide area wireless paging system as described above, the range of call transfer according to the present invention is possible in all regions, and the transfer of calls to other regions as well as the transfer between pagers in the country to satisfy the various requirements of the subscriber or the difference in service charges. Make it possible. In addition, since the subscriber should be able to find the corresponding NO.7 wide area network 106 by translating the pager number of the other region registered with the subscriber, it provides the function of associating the station number with the number of the wide area service network. To this end, the TDX-PS system assigns a wide area service area code corresponding to a station number to be registered when registering a station number. Therefore, when the station number information is output, the wide area service area code associated with the corresponding station number is output.

Registration, cancellation, confirmation, etc. of the call transfer function of the present invention is performed by both the subscriber phone or the VMS subscriber.

First, the processing sequence of call registration, cancellation, and confirmation by the subscriber's phone is as follows. The registration sequence consists of 015 + incoming pager number + [call tone] + * 88 + password + transfer pager number + * + [confirmation tone]. The cancellation sequence consists of 015 + incoming pager signal + [call tone] + # 88 + [confirmation tone]. The confirmation sequence consists of 015 + incoming pager number + [call tone] + * 81 + password + transfer pager number + * + [confirmation tone]. 15 in the sequence is a radio calling service number. The called pager number is its pager number. * 88, # 88, * 81 are additional service codes related to transfer, * 88 is transfer registration code, # 88 is transfer transfer cancellation code, and * 81 is transfer transfer confirmation code. [Call Tone] is a tone sent to the calling subscriber by the wireless paging system, a password is a unique password of the subscriber, * is an end code, and [OK] is a busy tone or normal for an error. It is a confirmation tone indicating performance.

2 is a flowchart illustrating a transfer registration, cancellation, and confirmation process by a subscriber telephone according to an embodiment of the present invention as described above. For example, if a subscriber dials 015 + incoming pager number to PSTN (100A or 100B) via a subscriber's phone, it is called to corresponding PT 112 through relay line matching unit 108 and number translation unit 110. . Then, the PT 112 connects a ring tone to the calling subscriber at step 200, and the calling subscriber inputs one desired additional service code among * 88, # 88, and * 81. Then, the PT 112 performs registration, cancellation, and confirmation functions according to the additional service code received in steps 202 to 208. If the transfer registration code is * 88, if the correct password is received from the calling subscriber in steps 210 and 212, the pager number to be transferred is received in step 214, and the calling subscriber is sent in step 216. After the confirmation sound is connected to the call, in step 218, the transfer is registered in the database that stores the transfer information and the transfer is terminated. On the other hand, if the transfer cancellation code # 88 is connected to the calling subscriber in step (220), the transfer registration is canceled and terminates in step (222). If the transfer confirmation code is * 81, if the password is received from the subscriber in steps 224 to 226 and is correct, the transfer pager number is received in step 228, and the transfer is registered in step 230. After confirming, connect the confirmation tone to the subscriber in step 232 and terminate.

Therefore, the subscriber's phone can not only register or cancel the transfer but also confirm.

Unlike the above, the VMS service subscriber can register, cancel or confirm the transfer. If VMS service subscriber wants to register, cancel, and confirm transfer while receiving subscriber service through PSTN (100A or 100B), enter transfer service code first and then enter registration code or cancellation code or confirmation code. . For example, the call transfer service code may be set to a dialing digit 7, a registration code to 1, a cancellation code to 2, and a confirmation code to 3.

Referring now to FIG. 3, which shows a flow of registration, cancellation and confirmation processing of a transfer by a VMS service subscriber according to an embodiment of the present invention, a call transfer service code in service for a VMS subscriber in steps 300 to 302. If is received, the process waits for the registration, cancellation, and confirmation code reception in steps 304 and 308. At this time, when the registration code is received, the VMS matching unit 108 is connected to the VMS service subscriber in step 310 to send a registration guide message, and the call transfer pager number transmitted by the VMS service subscriber in steps 312 to 314. After receiving the registration process and sends a confirmation message in step (316). At this time, for example, the registration guide message is sent to Please press the pager number to be switched to, and the confirmation message is sent to the user as registered or failed to register or already registered. On the other hand, if a cancellation code is received, the call transfer is canceled in steps 318 to 320 and a confirmation message is sent. This confirmation message will occasionally cancel, for example, your transfer number. I failed to cancel. Or You are not registered for transfer. If a confirmation code is received, the confirmation message is sent in steps 322 to 324, and then a confirmation message is sent. The confirmation message at this time, for example, you are not registered transfer feature. The number you switched to is xxxxxxx.

Therefore, the transfer can be registered or canceled by the VMS service subscriber as well as confirmed.

4 is a flowchart illustrating an example of a call processing procedure according to an embodiment of the present invention, which shows a processing example in which there is a call for a pager registered to transfer to a pager subscribed to another radio calling system by the above-described process. An embodiment of a call transfer will be described in detail with reference to FIG. 5 showing a receiver station processing flowchart according to an embodiment. For example, when the wireless calling system 102A of FIG. 1 becomes a calling station and another wireless calling system 102C in another region becomes a called station, that is, a call transfer registration to a pager subscribed to the wireless calling system 102C. It is assumed on the assumption that any subscriber of the PSTN 100A calls the subscription pager of the established wireless paging system 102A.

First, when there is a call from any subscriber of the PSTN 100A, the number translation unit 110 connected through the relay line matching unit 108 of the wireless paging system 102A translates the incoming pager number in step 400. Call to the PT (112). In the PT 112, after connecting a ring tone to the calling party in step 402 and receiving a message, in step 404, a call transfer number and a wide area network number are read from a database storing call transfer information. Transmit to wide area processing unit 114. The call transfer / wide area processing unit 114 determines whether the call is a global service call or a call transfer in step 406, and transmits the packet data by the data processing unit 116 to the call transfer number and the message for the incoming pager number. As a result, it transmits through the NO.7 wide area network 106 to the radio calling system 102C which is the called station to which the pager of the transfer number is subscribed.

Then, the data processing unit 116 of the wireless calling system 102C serving as the destination station transmits the received packet data to the call transfer / wide area processing unit 114 at step 500. The transfer / wide area processing unit 114 reads the transfer number included in the packet data in step 502 and requests a translation to the number translation unit 110. In step 504, the number translation unit 110 searches for the index of the database where the transfer number is registered, that is, the index of the main processor (MP) number and the pager information storage table. 114). Then, the transfer / wide area processing unit 114 requests an incoming call with the received message to the corresponding PT 112 in step 506. Then, in step 508, the destination PT 112 obtains paging information about the pager number transferred and wirelessly calls through the transmitter 104C. The paging information refers to information such as an RF channel number, a capcode, an encoding type, etc. required for a radio call.

Therefore, only local pager can transfer a call between other regions and other wireless paging systems in the same region.

On the other hand, the output form of the pager during the call transfer wireless call as described above is as follows. First, in the case of a call message, a part of the pager number transferred is included in the message to be displayed on the transfer pager. That is, when the message information is output to the incoming call pager, the last two digits of the pager number transferred in [] except for the station number are displayed. Accordingly, even if multiple pagers are transferred to one pager, they can be distinguished. For example, when the subscriber A whose number is 300-1234 is switched to the subscriber B, it is displayed on the subscriber B's pager as xxxxxxxxxxx [34]. On the other hand, in the case of recording a message, a received message is outputted to the pager number transferred as in the prior art, and thus it is easily distinguished.

In addition, the registration, cancellation, information change, information output of the call transfer function according to the present invention as described above is made by the operator.

As described above, the present invention can not only transfer a call between other regions and other wireless paging systems in the same region by using a local pager, but also have an advantage in that the reception rate is improved because there is no overlapping region. In addition, when the incoming call is received, the pager transferred can be checked, and the function can be registered by the subscriber phone or the VMS subscriber.
