DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective call receiver, and more particularly to a multi-area radio selective call receiver having a radio information receiving function.

[0002]

2. Description of the Related Art In recent years, radio selective calling not only performs radio selective calling individually for receivers, but also provides a common radio address to a plurality of radio selective calling receivers to provide news and weather forecasts. An information providing service for transmitting a common information message is also provided, and one wireless selective call receiver performs a function corresponding to two services, a wireless selective call service and an information providing service.

Conventionally, when a receiver using the selective paging service moves from one area to another, an operator providing a selective paging service (hereinafter referred to as an “entrepreneur”) uses the selective paging service in the destination area. ) Had to be contacted and registered.

[0004]

SUMMARY OF THE INVENTION In the case of a multi-area radio selective call receiver using both the radio selective call service and the above-mentioned information providing service, if the user moves to an area using the radio selective call service, he / she moves. It is necessary to contact the operator to receive the individual selective call in the destination area, but if you move to the area that uses the information provision service that makes a call with a common address, the radio that receives the call service The address may be automatically switched, and there is no need to register to switch the area for receiving the call service. The area in which the radio selective call service is performed for one radio selective call receiver and the area in which the information providing service is provided do not necessarily need to coincide with each other. By notifying the switching of the area, and receiving the registration of the receiver carrying out the switching of the calling area, it is possible to prevent the switching registration from being complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a multi-area radio selective call receiver that utilizes both a radio selective call service and an information providing service to avoid unnecessary notification and area registration at the time of service area switching and to avoid radio selection. The purpose is to improve the efficiency of both calling and information providing services.

[0006]

SUMMARY OF THE INVENTION A multi-area radio selective calling receiver according to the present invention uses a radio channel switching receiving means for sequentially switching a plurality of radio channels and receiving for a fixed time, and a certain signal system adopted by the receiving channel. A selective call area setting means for setting a specific service area using a radio selective call service as a selective call area in a storage means in the radio selective call receiver; Broadcasting means and the radio channel receiving for a certain period of time adopt a certain signal system,
And when it has separately defined area identification information, reception is continued without switching the receiving radio channel, synchronization is established, and the service area indicated by the above area identification information is set by the selective calling area setting means. When the area is the selective calling area, there is provided a service area switching control means for operating the notifying means to notify the switching of the service area.

[0007] A receiving function utilizing a certain radio information providing service is to provide a common radio address to a plurality of radio selective calling receivers and to transmit a common information message such as news and weather forecast when no selective calling is received. It may be a function of receiving.

The selective paging area setting means includes a selective paging area together with a radio address and area identification information in an iDROM of a receiver by a provider of a radio selective paging service before use of an individual radio selective paging receiver. May be the first selective call area setting means for setting the number.

The selective call area setting means selects the selective call area set in the iDROM from the selective call area set in the iDROM by the carrier of the radio selective call receiver in the service area switching control means, and sets the selected call area as needed. It may be a second selective call area setting means that can perform the setting.

The wireless channel switching reception means has a timer for setting a time from when the reception state deteriorates and synchronization cannot be maintained to when the switching reception operation is started, and the switching reception operation is performed after the set time of the timer elapses. May be started.

[0011] The time set by the timer may be longer when synchronization cannot be maintained in the selective call area than in a service area other than the selective call area.

According to the service area switching control method of the present invention, when the reception state of a radio channel deteriorates and synchronization cannot be maintained, a plurality of radio channels are sequentially switched to receive for a certain period of time, and a signal system adopted by the reception channel is used. Detected, if the signal system matches a certain signal system, refer to the area identification information of the new radio channel being received, and if the area identification information is area identification information separately determined, the radio channel being received Continue receiving without switching
Synchronization is established. If the service area indicated by the area identification information is a service area using the selective call service, the service area switching is reported. If the service area uses only the radio information providing service, the service is provided. Does not report area switching.

A fixed timing may be taken from when the reception condition of the radio channel is deteriorated and the synchronization cannot be maintained until the reception of the radio channel switching is started.

The above timing differs between the selective calling area and the information calling area, and may be larger in the selective calling area.

[0015]

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a radio selective calling receiver according to the present invention.

A radio selective calling receiver (hereinafter abbreviated as a receiver) shown in FIG.
It comprises a control unit 120. The control unit 120 includes:
IDRO for storing operator setting information such as a wireless address, a wireless channel scan list, and service area identification related information set by the operator before using the receiver
M, an external interface 126 used to set the carrier setting information in the iDROM, a signal analysis unit 123 that analyzes a demodulated signal output from the reception demodulation unit 110, a reception channel is specified, and the reception demodulation unit 110 and the signal analysis unit are designated. 12
3, a reception control unit 124 for controlling the operation of the receiver 3, a notification unit 127 for notifying the receiver of the receiver by sound, light, or vibration when a radio selective call or an information provision call is received or when the receiver is moved. A display unit 128 for displaying a message received along with the call or an information message related to the area switching, a switch 129 for setting an area to be notified of the area switching by an operation of a receiver carrier, and a controller 125 are provided. include.

The controller 125 takes in the business setting information in the iDROM into the internal memory 122 as needed,
The operation of each unit in the control unit 120 is controlled. iDROM1
21 includes information indicating whether or not the area is to use the selective call service. The information is stored in the internal memory 122 before the movement of the receiver. The carrier setting selective calling area, which is selected and set by the receiver carrier at any time from the selective calling area by the receiver, is set in the internal memory 122. The reception control unit 124 controls the controller 12 when the operation starts or when it is necessary to switch the area.
5 is supplied with necessary information from the internal memory 122, controls the operations of the reception demodulation unit 110 and the signal analysis unit 123, monitors the outputs thereof, and performs operations such as maintaining synchronization.

The controller 125 includes a signal analyzer 12
3. The reception control unit 124 sets the radio channel of the new area
When captured, the base information code indicating the area is read from the output of the signal analysis unit 123, and is compared with the base information code including the area identification information in the internal memory 122, and the area is selected to use the radio selective calling service or the information providing service. If it is a paging area, when it is detected that synchronization has been established for the wireless channel, it is further determined whether or not the area is to be switched to an area to be notified, and the new area is switched to an area. If it is a selective call area to be notified to the user, the notification unit 127 and the display unit 128 are operated to notify the receiver carrier. Also,
If the new area is only an information providing service which does not need to notify the receiver carrier, the notification unit 127 is not operated. At this time, the wireless address is changed.

FIG. 2 is a flowchart showing an area switching operation in the receiver shown in FIG.

The reception control unit 124 sequentially switches the radio channels to be received and demodulated by the reception and demodulation unit 110 in accordance with the radio channel scan list read from the iDROM 121, and receives and demodulates the reception channels at fixed time intervals (step 201). When the signal analysis unit 123 detects a certain synchronization signal within a certain time (step 202), it receives the base information code (step 204), and the base information code decoded by the signal analysis unit 123 is stored in the internal memory 122 of the controller 125. It is determined whether or not it matches the base information code (step 205). If the base information code matches, it is an area where the selective call service or the information providing service can be used. Synchronization is established with the middle wireless channel (step 206). At this point, the controller 125
Refers to the internal memory and determines whether or not the area indicated by the base information code of the newly established area is the area to be notified to the receiver carrier of the area switching as switching to the selective calling area ( Step 207),
If the area is a selective call area to be informed, the notification is made using the notification unit 127 and the display unit 128 (step 208). If the area is dedicated to an information providing service, the selective call or the information providing call is received without being notified. The operation shifts to the operation and synchronization monitoring operation (step 209). When a certain synchronization signal to be obtained within a certain time is not detected in step 202 and timeout occurs, and when the base information code decoded by the signal analysis unit 203 does not match the base information code held in the internal memory 122 in step 205 Returns to step 201 after waiting for the next channel search (step 203). If the reception condition deteriorates in step 209 and synchronization cannot be maintained, step 2
Return to 01. Note that the receiver carrying the area switching notification in step 208 reports the switching to a new area to the business operator and registers the area.

FIG. 3 shows an example of information stored in the internal memory 122 of the controller 125 in relation to the control of switching the service area. In the example of FIG. 3, the carrier setting information includes a base information code including identification information of each area taken from the iDROM and information indicating whether or not the area is available for the selective calling service. In the table, there is shown an area which is selected by the receiver carrier from available areas of the selective call service and which is set as an area to be switched and notified of an area, and which is not set.

In FIG. 3, the operator providing the radio selective calling service has a radio selective calling service in seven areas of Tokyo, Kanagawa, Shizuoka, Aichi, Gifu, Kyoto and Osaka, and a common radio selective calling service. It provides information provision services, and the remaining three areas, Chiba, Saitama, and Ibaraki, are set as areas for information provision services only. in this case,
The receiver carrier does not need to select whether or not to perform the area switching notification for the three areas of Chiba, Saitama and Ibaraki. For example, the receiver travels to the Nagoya / Kanagawa / Shizuoka route from the Tokyo area where it is normally used for business trips, etc., temporarily works in Nagoya, and then travels to Kyoto / Osaka via Gifu. Assuming that, the receiver carrier sets the receiver to Aichi / Kyoto / Osaka in addition to Tokyo as an area requiring area switching notification before starting movement. Leaving the Tokyo area, Kanagawa
When traveling to Shizuoka, the area switching is performed but the area switching is not notified, and the information message provided during that time can be received. Then, when the vehicle arrives in the Aichi area, an area switching notification is performed, and the receiver carrying the information can receive a selective call service by performing area registration. Similarly, when traveling from the Aichi area to the Kyoto / Osaka area, while traveling to the Kyoto area, you can receive extra area switching information and receive information only without having to worry about area registration. Becomes

FIG. 4 shows the receiver of FIG. 1 provided with a scan start timer. In the flowchart of FIG.
FIG. 9 is a diagram showing a flow of an area switching operation in a case where a certain timing is taken until a channel search according to a channel scan list is started after synchronization cannot be maintained; An example is shown in which the timing up to the start of the channel search is set to be different between the non-use areas. The flow until the notification of the area switching, that is, the operation from step 401 to step 407 in FIG. 4 is the same as the operation from step 201 to step 207 in FIG.

In FIG. 4, in step 407, it is determined whether or not the area is a selective call service use area. If it is determined that the selective call service is in use area, in step 408, the area switching is notified and at the same time, a scan start timer built in the controller 125 is provided. set the timer value T to T ₁ (step 409), whereas immediately when it is judged not to be the available area of the selective call service in step 407, to set the timer value T of the scan start timer T ₂ (step 41
0), if there is an incoming call, it responds to this and at the same time shifts to synchronous monitoring (step 411).

The operation proceeds to the message receiving operation and the synchronization monitoring operation, and while the synchronization maintaining judgment is repeated (step 41).
2) If the signal analysis unit 123 cannot detect the synchronization signal in the received data and cannot maintain the synchronization, the reception control unit 1
24 starts a scan start timer (step 41).
3), resynchronization pull-in operation is repeated (step 41)
4) If the signal analysis unit 123 cannot reacquire the synchronization signal before the timer value reaches T1 or T2, the area switching operation starting with the channel search is restarted (step 4).
15). Here, by setting the timer setting values T1 and T2 so that T1> T2, in the area where the area registration notification is performed based on the area switching notification, the re-supplement operation of the synchronization signal is performed longer. The registered area will be maintained as much as possible. This makes it possible to
Even when the user temporarily moves to a place where the electric field is weak, it is possible to prevent the area selection operation from being prematurely performed. On the other hand, in an area where the area registration notification is not performed, by immediately shifting to the next area selecting operation, it is possible to prevent an information message that is frequently transmitted at short intervals from being missed.

[0026]

According to the present invention, the area to be notified of the area switching is determined in advance, so that the area switching is not complicatedly notified, and the number of area registrations can be reduced. Becomes possible.

Depending on whether the area where the receiver is used is an area using the selective call service or an area using only the information providing service, the timing of starting to search for the next area is changed, thereby improving the service efficiency of each area. Can be planned. Further, by switching the wireless address, the wireless address can be efficiently stored in the receiver.
