Abstract

PROBLEM TO BE SOLVED: To judge whether a system can be tuned to the received radio communication of a radio selection call base station by comparing hierarchy address information received from one radio selection call base station with hierarchy address information stored in a hierarchy address storage part. SOLUTION: A tuning judgment part 3 compares/collates hierarchy address information stored in the hierarchy address storage part 2 with hierarchy address information from a pager base station, which is inputted from a reception part 1, and judges whether hierarchy address information are matched or not. When hierarchy address information are matched, the tuning judgment part 3 judges that tuning to the pager base station receiving radio communication is possible and continues the tuning of radio communication in the reception part 1. When hierarchy address information are not matched, the tuning judgment part 3 judges that tuning to the pager base station is impossible, outputs a tuning release instruction to the reception part 1 and changes the frequency of received radio communication.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective calling receiver for receiving radio communications from a plurality of radio selective calling base stations, and a receiving method thereof.

[0002]

2. Description of the Related Art In recent years, radio selective calling receivers (hereinafter referred to as "pager receivers") have been put to practical use in various systems. For example, in an RDS (Radio Data System) type pager system, an FM broadcast station is used as a radio selective calling base station (hereinafter, referred to as a “pager base station”).
The transmission information is superimposed on the subcarrier of the FM broadcast wave and transmitted to the pager receiver. Specifically, the pager base station transmits a modulated signal including a call number and message data. The pager receiver retrieves the called number by receiving and demodulating the transmitted modulated signal. Next, the pager receiver compares the retrieved call number with a previously stored call number, and if the call numbers match, stores the received message data. At the same time, the pager receiver performs a calling operation by a display or a buzzer sound.

Hereinafter, a conventional pager receiver will be specifically described with reference to FIG. 15 and FIG. FIG.
FIG. 1 is a block diagram showing a configuration of a conventional radio selective calling receiver. FIG. 16 is a simplified configuration diagram showing an example of a signal format of wireless communication from the radio selective calling base station received by the radio selective calling receiver shown in FIG. FIG.
As shown in FIG. 1, a conventional pager receiver includes a receiving unit 51,
Call number storage unit 5 for storing at least one call number
2, and a call number collating unit 5 connected to the receiving unit 51
3, a message acquisition switch 54 and a message block acquisition end recognition unit 55 are provided. Further, the conventional pager receiver has a message writing unit 56 connected to the message acquisition switch 54, and a message storage unit 57 connected to the message writing unit 56. Receiving section 51 tunes to and receives a modulated signal of a fixed frequency transmitted from a pager base station (not shown), and outputs the demodulated data to call number collating section 53 and message block end recognizing section 55. The data is also output to the message acquisition switch 54 in an invalid state (off state). The call number collating unit 53 compares and compares the call number stored in advance in the call number storage unit 52 with the call number input from the receiving unit 51, and determines whether the call numbers match. For example, when the wireless communication shown in FIG. 16 is performed from the pager base station,
The call number matching unit 53 checks whether the call number stored in the call number storage unit 52 matches the call number M or the call number O. If the call numbers match, the call number collating unit 53 outputs a valid signal to the message acquisition switch 54 to put the switch into a valid state (ON state). As a result, the demodulated data is output to the message writing unit 56. For example, when the call number M is stored in the call number storage unit 52, the message writing unit 56 extracts the message N illustrated in FIG. 16 and stores the message N in the message storage unit 57. When the call number O is stored in the call number storage 52, FIG.
The message P shown in FIG.
7 is stored. Message block acquisition end recognition unit 55
Recognizes the end of the received message, invalidates the message acquisition switch 54. By these operations, the data received from the time when the message acquisition switch 54 is made valid by the call number collating unit 53 to the time when the message acquisition switch 54 is made invalid by the message block acquisition end recognition unit 55 are stored in the message storage unit. 57.

Judge whether or not. When the hierarchical address information matches, the tuning determination unit 3 determines that tuning to the pager base station that has received the wireless communication is possible, and continues the tuning of the wireless communication in the receiving unit 1. When the hierarchical address information does not match, the tuning determination unit 3 determines that tuning to the pager base station is impossible, outputs a tuning release command to the receiving unit 1, and changes the frequency of the wireless communication to be received. I do. The call number collating unit 5 compares and compares the call number stored in advance in the call number storage unit 4 with the call number input from the receiving unit 1, and determines whether or not the call numbers match. If the call numbers match, the call number matching unit 5
A valid signal for setting the switch to a valid state (ON state) is output to the message acquisition switch 6. As a result, the demodulated data is output to the message writing unit 8. The message writing unit 8 extracts the message data associated with the matched calling number, and stores the message data in the message storage unit 9.

Next, with reference to FIGS. 2 to 5, hierarchical address information used in the pager receiver of the present embodiment will be specifically described. FIG. 2 is an explanatory diagram showing a configuration example of a service area network having a hierarchical structure, which is constituted by a plurality of radio selective calling base stations which perform radio communication with the radio selective calling receiver shown in FIG. FIG. 3 is a diagram illustrating an example of hierarchical address information stored in the hierarchical address storage unit illustrated in FIG. FIG. 4 is a simplified block diagram showing an example of a signal format of wireless communication received by the radio selective calling receiver shown in FIG. 1 from a radio selective calling base station. FIG.
FIG. 5 is a diagram illustrating a specific example of hierarchical address information illustrated in FIG. 4.
First, as shown in FIG. 2, the service area network in which the pager receiver of the present embodiment is used is composed of four layers including a global zone, a country zone, a major zone, and a minor zone. The global zone is the highest level of the service area network,
It is composed of multiple country zones, such as Germany and the United States. For example, country zones in Japan, Germany, and the United States are provided with country zone codes 81DF, 80AC, and 81CC, respectively, for identification. Each country zone, for example, the United States 81CC, has a plurality of major zones 8081,8082,8083 assigned a unique major zone code.
And the like. Similarly, each major zone,
For example, the major zone 8081 includes a plurality of minor zones 8081,
8082, 8083 and the like. In each minor zone, for example, the minor zone 8082, a plurality of pager base stations 20, 21, 22, and 23 are assigned. These pager base stations 20, 21, 22, 23
Performs wireless communication with the pager receiver using different frequencies. The pager base stations 20, 21, 22, and 23 have a local area code 8 to identify each other.
0, 81, 82, and 83 are respectively provided. In the minor zone 8082, six pager base stations to which local area codes A0, A3, B3, DA, FD, and 39 are respectively assigned are also assigned. As described above, in a service area network having a hierarchical structure, each pager base station is provided with a unique code (number) for each layer and configured to be identifiable from each other. The hierarchical address information includes a country zone code, a major zone code, a minor zone code, and a local area code given to each pager base station.

The hierarchical address information stored in the hierarchical address storage unit 2 (FIG. 1) corresponds to the service area network shown in FIG. 2, and indicates the pager base station to which the pager receiver can tune at the present time. I have. Specifically, as shown in FIG. 3, the hierarchical address storage unit 2 stores, for example, a country zone code 81CC, a major zone code 8081, and a minor zone code 8 as hierarchical address information.
082 and the local area code 80 are stored. On the other hand, the pager base station transmits a modulated signal including hierarchical address information A and message information V and W as shown in FIG. For example, the pager base station 20 (FIG. 2) uses the country zone code 81CC and the major zone code 80 shown in FIG.
81, a minor zone code 8082, and a local area code 80. The message information is
It consists of a call number and a message. For example, as shown in FIG.
And message C, and the message information W is composed of a call number D and a message E.
When the hierarchical address information matches and it is possible to tune to one pager base station, as described above, the received call number and the call number storage unit 4 are stored by the call number collating unit 5 (FIG. 1). Comparison and collation with the call number stored in (FIG. 1) are performed. At this time, for example, when the call number B is stored in the call number storage unit 4, the call number B
Is extracted and stored in the message storage unit 9 (FIG. 1) by the message writing unit 8 (FIG. 1).

Next, the operation of the pager receiver of this embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing the operation of the radio selective calling receiver shown in FIG. In FIG. 6, as shown in step S1, when receiving section 1 (FIG. 1) receives wireless communication from one pager base station, receiving section 1 demodulates the modulated signal of the received wireless communication and performs the modulation. The hierarchical address information included in the signal is output to the tuning determination unit 3 (FIG. 1). Further, the receiving section 1 outputs the message information included in the modulated signal to the call number collating section 5 (FIG. 1), the message acquisition switch 6 (FIG. 1), and the message block acquisition end recognition section 7 (FIG. 1). . Subsequently, as shown in step S2, the tuning determination unit 3
Indicates that the received hierarchical address information is stored in the hierarchical address storage unit 2.
It is determined whether or not the address matches the hierarchical address information stored in (FIG. 1). When the hierarchical address information matches, as shown in step S3, the tuning determination unit 3
It is determined that tuning to the received wireless communication is possible, and tuning is continued. Then, the call number collating unit 5 compares and compares the call number included in the message information with the call number stored in the call number storage unit 4 (FIG. 1). When the call numbers match, the call number collating unit 5 turns on the message acquisition switch 6. As a result, as shown in step S4,
The message accompanying the matching call number is written into the message storage unit 9 (FIG. 1) by the message writing unit 8 (FIG. 1). When the call numbers do not match, that is, when the call number included in the received modulation signal of the wireless communication is not stored in the call number storage unit 4, the pager receiver ends the operation. If the hierarchical address information does not match, as shown in step S5, the tuning determination unit 3
It determines that it is not possible to tune to the received wireless communication, and outputs a tuning release command to the receiving unit 1. More specifically, when the pager receiver receives a wireless communication from the pager base station 21 in a service area of the pager base station 21 (FIG. 2), for example, the tuning determination unit 3 sets the country shown in FIG. Zone code 81CC, major zone code 808
1. The minor zone code 8082 and the local area code 81 are received from the pager base station 21 as hierarchical address information. On the other hand, when the hierarchical address storage unit 2 stores the hierarchical address information, the country zone code 81CC, the major zone code 8081, the minor zone code 8082, and the local area code 80 shown in FIG. In the address information, the local area codes do not match. As a result, the tuning determination unit 3 determines that tuning to the pager base station 21 is impossible. Subsequently, the receiving unit 1 changes the frequency of the modulated signal to be received as shown in step S6. As described above, in the pager receiver according to the present embodiment, the hierarchical address storage unit 2 stores the hierarchical address information of the tunable pager base station, and the tuning determination unit 3 receives the hierarchical address information received from one pager base station. And the hierarchical address information stored in the hierarchical address storage unit 2 is compared.
Therefore, in the pager receiver of the present embodiment, the tuning determination unit 3 can determine whether or not it is possible to tune to the received wireless communication of the pager base station.

Next, the operation of the pager receiver when the hierarchical address storage unit 2 stores the hierarchical address information shown in FIG. 8 will be described. As shown in FIG. 8, the local area code of the hierarchical address information is set to “FF”. When "FF" is set, the tuning judging section 3 operates to ignore the comparison result of the local area code. That is, when the country zone code, the major zone code, and the minor zone code of the received hierarchical address information are stored in the hierarchical address storage unit 2, the tuning determination unit 3 determines that tuning to the received wireless communication is possible. With this configuration, it is possible to secure a wider tunable range than a pager receiver that stores one local area code in the hierarchical address storage unit 2. Similarly, in the hierarchical address storage unit 2, when the minor zone code and the local area code of the hierarchical address information are set to “FFFF” and “FF”, respectively, as shown in FIG. 3 operates so as to ignore the comparison result of the minor zone code and the local area code. That is, when the country zone code and the major zone code of the received hierarchical address information are stored in the hierarchical address storage unit 2,
It is determined that tuning to the received wireless communication is possible. With this configuration, it is possible to secure a wider tunable range than a pager receiver that stores one local area code in the hierarchical address storage unit 2. When the country zone code, major zone code, and minor zone code are set to “FFFF” and the local area code is set to “FF”,
The pager receiver can ignore the comparison result of the hierarchical address information in the tuning determination unit 3 and secure the maximum tuning range.

Further, in the pager receiver of this embodiment, a plurality of local area codes can be set in the hierarchical address storage unit 2. In the hierarchical address storage unit 2, for example, as shown in FIG. 10, four local area codes 1, 2, 3, 4 are provided, and 80, 81, 82,
83 can be set respectively. Further, as shown in FIG. 11, the local area codes 1 to 4 are A0, A
3, B3, DA, the pager receiver sets the local area codes A0, A3, B3,
It is possible to tune to all wireless communications from the four pager base stations (FIG. 2) to which the DAs are assigned.

<< Second Embodiment >> FIG. 12 shows a second embodiment of the present invention.
It is a block diagram which shows the structure of the radio selective calling receiver which is an Example of. FIG. 13 is a simplified configuration diagram showing an example of a signal format of wireless communication received from the wireless selective calling base station by the wireless selective calling receiver shown in FIG. In this embodiment, in the configuration of the pager receiver, a data discriminating unit for discriminating the content of the data of the wireless communication from the pager base station is provided. The hierarchical address information stored in the address storage unit is changed. The other parts are the same as those shown in the first embodiment, and the duplicate description thereof will be omitted. As shown in FIG. 12, the pager receiver is connected to the data discriminator 10 connected to the output terminal of the message acquisition switch 6, and is connected to the data discriminator 10. A section 11 is provided. The message writing unit 8
Is connected to the message acquisition switch 6 via the data discriminator 10 unlike the first embodiment. Each pager base station transmits a modulation signal including hierarchical address information F, message information X and Y, and hierarchical address write information Z, for example, as shown in FIG. The hierarchical address information F and the message information X and Y are the same information as the hierarchical address information A and the message information V and W shown in FIG. Further, the hierarchical address write information Z includes the call number K and the hierarchical address write data L.
It is composed of Hierarchical address write data L
Is composed of codes in each layer for specifying and identifying one pager base station, like the layer address information A and F. When the hierarchical address information and the call number of the wireless communication received by the receiving unit 1 match those stored in the hierarchical address storage unit 2 and the call number storage unit 4, respectively, the data determination unit 10 Then, the contents of the modulation signal of the wireless communication input from step 6 are determined.

Here, with reference to FIG. 14, a description will be given of the content discriminating process of the wireless communication by the data discriminating unit 10 and the subsequent writing process. The comparison and collation processing of the hierarchical address information by the tuning judgment unit 3 and the comparison and collation processing of the call number by the call number collation unit 5 are the same as those in the first embodiment. Omitted. FIG.
13 is a flowchart showing the operation of the radio selective calling receiver shown in FIG. In FIG. 14, as shown in step S7, the data determination unit 10 determines which of the message information and the hierarchical address write information has been received. When the message information is input, the data determining unit 10 outputs the message information to the message writing unit 8. Subsequently, the message writing unit 8 stores the message included in the input message information in the message storage unit 9 as shown in step S8. This allows the user to be notified of the message from the pager base station. When the hierarchical address write information is input, the hierarchical address write information is output to the hierarchical address write unit 11. continue,
The hierarchical address writing unit 11 writes the hierarchical address write data included in the input hierarchical address write information into the hierarchical address storage unit 2 as shown in step S9. As a result, the hierarchical address information stored in the hierarchical address storage unit 2 is changed, and the tunable pager base station of the pager receiver is also changed.

As described above, in the pager receiver of the present embodiment, the data discriminating unit 10 discriminates the contents of the wireless communication from one pager base station. When receiving the hierarchical address write information, the hierarchical address write unit 11 rewrites the hierarchical address information stored in the hierarchical address storage unit 2. For this reason, by transmitting the hierarchical address write information from the pager base station, the storage content of the hierarchical address storage unit 2 of the pager receiver can be changed, and the tunable pager base station of the pager receiver can be easily identified. Can be changed.

In the first and second embodiments described above,
In each layer of the global zone, country zone, major zone, and minor zone, a 4-digit code is used as an identification number, and a 2-digit code is used as an identification number for each local area in the minor zone. However, these codes of the number of digits are merely examples, and the codes are not limited as long as the codes can identify each zone and pager base station. Also, the description has been made using “FF” and “FFFF” as codes for invalidating the hierarchical address information from the pager base station, but other predetermined codes may be used.
