Description

Method of paging to abroad in paging system

The present invention relates to an additional service of a wireless calling system, and more particularly, to a method of allowing a domestic calling party to receive a calling service in a visiting country.

In general, a wireless call system consists of a wireless call exchanger (TDX-PS) connected to a public telephone network (PSTN), a voice mail service device (VMS), a land base station, a callee management system, and a pager carried by the called party. Is a mobile communication system for calling people who are unclear or move frequently.

Here, the pager uses a Post Office Committee Standard Association Group (POCSAG) code, as disclosed in Korean Patent Publication No. 93-2749 (published April 9, 1993). Each call is assigned a unique code (called a "CAP code") corresponding to the call address of each pager.

The cap code is a unique number assigned to each radio pager, and is composed of 18 bits of magnetic address data and 3 bits of frame data included in an address codeword directly transmitted when a specific pager is called. Recently, services based on new protocols, such as FLEX and ERMES, are being provided for high-speed wireless paging services, and bidirectional paging related technologies are commercially available.

Such a wireless call system accesses a cap code corresponding to dial information received from a subscriber and propagates it to the air so as to make a corresponding wireless call, and the wireless pager receives and stores a cap code transmitted to the air in advance. If it matches with its own unique address, it recognizes that it is its own call, generates an alarm signal, and displays the telephone number entered by the other party.

On the other hand, the Voice Mail Service (VMS) means that if a person who wants to talk to a subscriber of a voice mail service can not speak directly with the subscriber, the user records a message in the voice mailbox and plays it at a desired time. Means a service that can be checked.

For example, if a person named Gap wants to send a message to a person named Gap by a message, Gap connects the call to the radio call number of the phone via a telephone. According to the announcement provided through the wireless paging exchange, press the button "2" which is the voice recording and input the voice message.

At this time, the VMS device records the voice message of the head, and when the "*" key is input, the voice recording is terminated and the call number of the call is made using the wireless transmission system of the base station. You will be informed that there is a voice message.

However, since the subscriber cannot receive the calling service in the conventional wireless calling service as described above, even if he wants to make a hasty call with the subscriber who is visiting overseas in Korea, he must wait with urgency until the subscriber calls first. Only did.

Accordingly, the present invention has been made in order to solve the above problems, and provides an overseas wireless calling method in a wireless calling system that allows a subscriber who is visiting overseas to be called even when only the domestic call number of the subscriber is pressed in the country. Its purpose is to.

In order to achieve the above object, in the method of the present invention, when a domestic subscriber travels abroad, the domestic terminal is replaced with a foreign terminal, and the subscriber's mailbox is switched from a domestic voice mail service device to an international roaming voice mail service device. Doing; Calling by a caller with a domestic call number; Performing a domestic call when the called domestic call number is located in the domestic voice mail service device; Searching for an overseas call number corresponding to a domestic call number if the called domestic call number is located in the international roaming voicemail service device; Connecting a call to the retrieved foreign call number and transmitting a caller's call message to an internet server of a corresponding station through an internet network; And calling the subscriber who is traveling abroad through the wireless calling system of the foreign country.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram schematically showing a wireless call system to which the overseas wireless calling method according to the present invention is applied.

Referring to FIG. 1, a wireless call system includes a voice mail service device 104 connected to a public telephone network 102 and a voice mail service device 104 connected to the wireless call exchange 103 to provide a voice mail service, and an international call service. Roaming voicemail service device 105, and a VMS server 106 for storing the visited station call number of the subscriber visiting abroad.

The wireless call system is connected to the Internet network 108 through the VMS server 106 and the web server 107, and the wireless call system of the visiting station visited by the subscriber is also connected to the Internet network (109) through the Internet server 109. 108).

Looking at how the domestic caller calls the domestic subscriber in the configuration as described above, the caller to the caller's call number (for example, 015-xxx-xxxx) through the telephone 101 connected to the public telephone network 102 When the call is made, it is connected to the subscriber matching section of the radio call exchanger 103 via the public telephone network 102. At this time, according to the guidance sound provided from the system of the wireless call exchanger 103 ("1 to call, 2 to record, ......"), select "1" and then his phone number And then press "asterisk (*)", the data carrying the telephone number is propagated to the air through the wireless transmission system of the base station according to a predetermined protocol.

If "2" is selected according to the guidance sound provided, the wireless call exchanger 103 connects the caller's telephone 101 to the voicemail service apparatus 104, and the voicemail service apparatus 104 calls the caller. Converts the voice message left to digital and stores it in the hard disk (HDU) of the subscriber area. When the storage of the voice message is completed, the wireless call exchanger 103 requests a telephone number that the caller wants to answer with a guide tone, and when the telephone number is entered, calls the wireless pager of the called party through the base station's wireless transmission system. Pass the number.

Then, when the called party recognizes the call and accesses the voice mail box through the telephone, the voice mail service device 104 reproduces the messages stored in the hard disk to call the callee through the wireless call exchanger 103 and the public telephone network 102. You hear it.
