DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a radio paging receiver and a radio paging system using the same.
In particular, the present invention relates to a location registration method when a radio selective call receiver (hereinafter, referred to as a pager) moves between radio call exchange areas.

[0002]

2. Description of the Related Art A conventional radio selective call receiver (pager) of this type of radio call system notifies a radio call exchange of position information via a communicable means when a position registration is changed, and a new reception frequency. A method of returning information to the pager, or recognizing the receiving frequency of the destination itself, notifying the location information via a means capable of communicating with the paging switch, and allowing the pager to receive a message in the corresponding area on the switch side. It is determined whether or not the transmission base station for calling is changed after the location registration information on the exchange side is changed if permission is granted (Japanese Patent Laid-Open No. 6-260981, JP-A-5-284095).

[0003]

A first problem with the pager of the above-mentioned conventional paging system is that the position registration of the pager is not changed through a means that allows the user to communicate with another paging exchange. That is, it gives the user troublesome use. This is because the pager itself does not have a function of transmitting a location registration request, and has been forced to use another communication means.

[0004] A second problem is that a pager cannot be called due to a user's neglect to change the location registration, and a traffic failure of a source radio pager occurs. Since the location registration information is not changed, the pager cannot be received in the destination area, and the source paging exchange must continue to call a pager that does not exist in that area, Is causing unnecessary high traffic.

[0005] The third problem is that since the exchange is determined not on the pager side but on the exchange side, even if the location registration request can be transmitted from the pager, the area to which the message has been transferred cannot be received. There has been a problem that a position registration request is made in spite of the prohibited area, or a position registration request is made constantly even though the user does not move between the areas.

[0006]

Next, the operation of the present invention will be described with reference to FIG.

A feature of the present invention is that a communication function of a communication system (PHS) different from a wireless call that can be transmitted to the pager 100 is provided. When the pager 100 moves from the area where the position is registered to another area, the pager 100 itself searches for the reception frequency of the movement destination, performs an inquiry on the received area ID and the message receivable area ID stored in the own pager, If you need to change the location registration,
A location registration request is automatically made to the wireless paging exchange via a system of a different communication system. At the same time, if the user moves to the message reception prohibited area, transmission of the position registration request is prohibited.

Next, the detailed operation of the pager 100 will be described. When the power is turned on (turned on), the pager 100 starts processing in the asynchronous mode (step S10 in FIG. 3).
0). The CPU 206 controls the PLL controller 205 based on the reception frequency information stored in the area ID storage memory 209.
Is written to the memory (step S11).
0). The pager 100 is then operated by the pager radio unit 2
In step 03, the reception of the radio call signal is started, and the synchronization pattern is detected by the synchronization detection unit 204. Here, if the synchronization pattern has not been detected, the reception frequency of another area is set to P again.
The LL data is changed, and the synchronization detection is continued (step S120). If a sync pattern is detected here,
The area ID is detected from the call signal received by the area ID detection unit 210. Here, the CPU 206 performs comparison with the previously detected area ID (step S130).

If the value does not match the previous value in the process of step S130 (it always does not match immediately after the power is turned on), the detected area ID is compared with the area ID (message receivable area ID) in the area ID storage memory 209. (Step S200), Message Receivable Area ID
If they match, the CPU 206 gives the transmission control unit 202 an instruction to transmit a position registration request. Transmission control unit 20
2 receives this instruction, starts a communication connection to PHS radio base station 103 through PHS radio section 201, and issues a location registration request to a corresponding one of radio paging exchanges 106 and 107 via public network 108. Perform (Step S210). Upon receiving the position registration request, the radio pager registers that the pager 100 exists in its area. When there is a call request to the pager 100 from the requester, the pager 100 is called through a transmission base station in its own area. Pager 1
When the location registration request processing is completed (step S220), the area name is displayed on the display unit 208 and the speaker 207 is sounded to notify the user that the message can be received (step S2).
30), a message reception waiting state is set (step S150).

If the message does not match the message receivable area ID in the process of step S200, the CPU 206
Does not instruct the transmission control unit 202 to transmit the location registration request, displays the area name and the message reception prohibition area on the display unit 208 and sounds the speaker 207 to prohibit the user from receiving the message. The state is notified (step S300). afterwards,
The pager 100 performs synchronization detection and area I at regular time intervals.
D detection is repeated (steps S160, S120, S1
30).

In the process of step S130, if the area ID matches the area detection detected last time, it is regarded that there is no movement between areas, and the area ID comparison of message reception / prohibition is not performed, but based on the previous comparison result. Processing is performed (step S140). That is, if the area ID is the message receivable area ID, the message reception standby is performed (step S150). If the area is not the message receivable area ID, the message reception standby is not performed. (Steps S160, S120, S130).

The pager 100 repeats the above series of processing (steps S110 to S300).

Next, the operation when the pager moves between two areas (pager area A and pager area B) of different reception frequencies having an area ID capable of receiving a message will be described. It is assumed that the pager 100 first exists in the pager area A, is registered in the location of the radio pager 106, and is in a message reception waiting state. Here, the pager 100 is in the pager area B
, The pager 100 cannot detect the synchronous pattern, and shifts to the asynchronous mode. The pager 100 in the asynchronous mode performs the synchronization detection while sequentially rewriting the PLL data, and the pager area B
When the receiving frequency is set to the PLL, the synchronization pattern is detected. After the synchronization is detected, if the area ID matches the message receivable area ID, the PHS wireless base station 103,
The wireless call exchange 10 at the destination via the public network 108
7 and sends a location registration request. In accordance with this, the destination paging exchange 107 adds the pager 100 to the stored location registration information, connects to the source paging exchange 106 via the public network 108, and transmits the location registration information. The source paging switch 106 deletes the pager 100 from the stored location registration information based on this information. As a result, the pager 100 can receive a message in the pager area B.

According to the present invention, since the location registration request in the radio pager is made through a transmission function of a different communication system capable of communicating with the radio pager mounted on the pager, the location registration request is issued by the user. You do not need to be conscious. Also, if you move between areas,
Since the pager automatically changes the position registration, a quick and accurate change operation is guaranteed.
