BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a wide area wireless paging service system to which the present invention is applied. 11 is a wireless paging dedicated network, 12 is a wireless paging system, and 13 is a bidirectional wide area terminal using a multi-channel system.

[0009] Since the constitution has an independent radio paging system (12) for each service area, it is possible to provide a local service, and such a local paging system (12) is connected through the radio paging network 11. ing. The radio call network (11) has a voice line and a data line, the voice line is used for connecting a call between the radio call systems (12), and the data line is subscriber information between the radio call systems (12). Used when giving and receiving.

Each local radio paging system (12) comprises a plurality of radio paging exchanges for handling forward and reverse radio paging and a plurality of radio paging transmission / reception systems (Base Station) for transmitting and receiving radio signals. In addition, each local radio paging system (12) communicates with the bidirectional wide area terminal (13) using the multi-channel method using the forward and reverse radio paging channels.

FIG. 2 is an example of a channel allocation method for each service area according to the present invention.

Each area is composed of two reference channels and at least one or more service channels, and the reference channel is allocated in each service area by selecting an appropriate one channel from existing service channels or new channels. The reference channel is defined as a reference channel, and the reference channel is used repeatedly depending on the degree of interference between service areas. All information transmitted through the forward reference channel includes a region code indicating the region, and when there is no information to be transmitted, dummy information having only the region code is transmitted to send a multi-channel wide area bidirectional terminal. Machine 1
3 ensures that the region is recognized by referring to the forward reference channel information.

FIG. 3 is a flowchart of a process of a bidirectional wide area terminal according to the multi-channel method according to the present invention.

At regular time intervals (for example, one hour),
Or when the subscriber desires (when pressing the switch)
Alternatively, when the service channel state in use is unreceivable, the forward reference channels assigned to the respective service areas are sequentially tuned (201) to search for receivable forward reference channels.

Thereafter, the region code contained in the information received over the forward reference channel is decoded (202), and the decoded region code matches one of the region codes for the forward reference channel. If it does not match (203), if it does not match, it tunes to the next forward reference channel (204), and then decodes the area code included in the information received through the forward reference channel (202). ), Iteratively executes, and stores the decrypted area code if it matches (20
5). At this time, since one reference channel is used in two or more areas at the same time, the reference channel can have two or more area codes, and all the two or more area codes must be confirmed. Must.

Thereafter, the decrypted area code is compared with the previously grasped and stored area code (206), and if the area code is different, the area movement is recognized (207). By retrieving the channel frequency information existing in the moving area, the reverse reference channel of the moving area and the own reverse service channel information assigned to the corresponding area are grasped (208). The area code and the subscriber identification number are transmitted to the radio calling system under jurisdiction (209). If the previously stored area code does not exist and the comparison cannot be performed (immediately after the terminal is powered on, etc.), the subsequent steps are executed as the area movement. Thereafter, the receiving unit of the terminal is switched to its own forward service channel assigned to the area indicated by the area code (210), and search for information received through the forward service channel is started (211 and 212). . If the channel status becomes unreceivable during a certain period of time while waiting for service, the next forward reference channel sequential tuning process (204) is repeated.

When the comparison result of the two area codes is the same, it is recognized that there is no area movement, and the receiving unit of the terminal is switched to the own forward service channel assigned to the area (210). The search for information received through the service channel is started (211 and 212). If the service waiting channel state becomes unreceivable for a certain period of time, the next forward reference channel is sequentially tuned (204)
Is executed repeatedly.

FIG. 4 is a structural diagram of a database possessed by the radio paging system.

When the subscriber subscribes to the radio call service in the home area, only one home area call number, subscriber terminal identifier (ID) information (cap code, etc.) and the area where the wide area service is applied And the service channel number in.

Here, the home area means an area where the subscriber mainly provides the service as the main residence area of the subscriber, and is 1 when the unidirectional radio paging service is provided only when the service channel number is allocated. Only forward service channel numbers (Cnf) are assigned, and forward and reverse service channel numbers (Cnf and Cnr) are assigned when performing bidirectional service.

FIG. 5 is a structural diagram of data that must be possessed by a multi-channel bidirectional wide area terminal when providing a wide area wireless paging service according to the present invention. Forward and reverse reference channel information), service channel information assigned to itself in the area, and identifier information (cap code, etc.) of the terminal itself.

In the service channel information, the unidirectional service has only the forward service channel information, and the bidirectional service has the forward and reverse service channel information. The terminal may check the area code by tuning only to the forward reference channel of the area to which the wide area service is subscribed.

FIG. 6 is a flowchart of the processing of the regional radio paging system according to the present invention.

The radio paging system subscribes to the area code corresponding to the area where the subscriber moves from the multi-channel bidirectional wide area terminal through the reverse reference channel or the own reverse service channel assigned to the area. If the person identification number is received (301), the received area code and subscriber identification number are decoded (302), and it is determined whether or not it is the home area of one's home (303).

When the home radio calling system has received the area code and the subscriber identification number as a result of the determination, the home radio paging system registers and updates the current location area of the subscriber in the database of the subscriber. (306).

If the result of determination is that the user is not in his / her home area, a data link with the home radio calling system is set (304), and the area code and subscriber identification number decrypted through the set data link are set. Is transmitted to the home radio paging system (305). At this time, in the home radio paging system, whether or not the area code and the subscriber identification number are correctly received is answered as "good reception (ACK)" or "bad reception (NACK)". The process of transmitting the area code and the subscriber identification number according to the response content is repeated one or more times. Here, the home radio paging system is a radio paging system located in the home area of the subscriber.

On the other hand, the home radio paging system which has received the area code and the subscriber identification number registers and updates the current location area of the subscriber in the database of the subscriber (30).
6).

FIG. 7 is a flowchart of the processing of the home radio paging system according to the present invention.

When a caller makes a call through a personal computer, a telephone, a portable communication device, etc., the general public telephone network (P
After the STN) identifies the called telephone network, the radio call is transmitted to the radio call system, and the radio call system receives the call (401) to determine whether or not it is the home area of the call. A judgment is made (402).

As a result of the judgment, in the case of own home area, the home radio paging system searches the database of the subscriber to confirm whether or not the subscriber is a valid subscriber (403), and then inputs the call message to the caller. A confirmation tone is generated (404). The home radio paging system receives a message including numbers, letters and special symbols from the caller and terminates the call (405) through the corresponding service channel in the form of a radio call signal in the form of a radio call signal and the message of the caller. Is transmitted (406).

As a result of the judgment, if it is not the home area of the user, the area radio calling system recognizes the home area by the calling number, and the home area radio calling system connects the call (407). The home radio paging system searches the database of the subscriber to check whether the subscriber is a valid subscriber (408), and then generates a confirmation tone (409) for inputting a paging message to the caller. The home radio paging system terminates the call after receiving a message containing numbers, letters, special symbols, etc. from the caller (410).
After that, the home radio paging system confirms the current location or area of the subscriber with the corresponding subscriber database (41
1) Transmit call information such as subscriber terminal identifier, service channel information, and message to the local radio call system of the confirmed area (412). The local wireless paging system in which the subscriber is located receives the paging information and sends the subscriber terminal identifier and the paging message in the form of a paging signal through the corresponding service channel (413).

The subscriber terminal searches for its own terminal identifier (cap code, etc.) while tuning to the forward service channel assigned to the area in which it is located, and If the terminal identifier is retrieved, the message is decoded and displayed on the liquid crystal display screen of the terminal along with a warning sound or vibration.

[0033]

As described above, according to the present invention, when a multi-way bidirectional wide area terminal is in a reception standby state on the current channel and it is detected through channel monitoring that the area has moved, it is assigned to each area. It searches the forward reference channel assigned to find out the current area, and tunes to its own forward service channel assigned to the area and waits for reception. Also, through the reverse reference channel and the reverse service channel assigned to the relevant area, the service area to which the user's current position belongs is transmitted to the radio paging system as a predetermined area code, and the wide area paging service is received. In this way, the efficiency of frequency use can be improved, and the inconvenience that the subscriber must call (use ARS) each time the service area moves and register the moving area in the radio paging system can be eliminated. There is.
