DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a radio communication system or a radio base station for transmitting distribution information from a radio base station to a radio terminal based on a request from the radio terminal itself or a device other than the radio terminal. The present invention relates to a wireless terminal and a reception control method for receiving the distribution information in a communication system for broadcasting.

[0002]

2. Description of the Related Art As a wireless communication system that provides multimedia information to a user at high speed by using wireless communication, a multimedia mobile access (MMA) is used.
a Mobile Access Communica
Tion)) Standardization of the system is in progress. Various applications using a wireless communication system capable of high-speed transmission such as the MMAC system are being studied. For example, if there is local information to be distributed locally, such as an advertisement for a specific area or information limited to a specific area, only the wireless base stations installed in the specific area wirelessly transmit the local area information. A service to transmit to the terminal is conceivable. It is also conceivable that these wireless base stations broadcast their local area information to all wireless terminals that can receive the local area information.

[0003] In a wireless communication system in which the wireless base station broadcasts the local information as described above, the wireless terminal receives the local information broadcast by the wireless base station regardless of the request of the wireless terminal itself. That is, the radio terminal receives the broadcast information every time it becomes possible to communicate with the radio base station broadcasting the regional information, so that the user does not perform the operation for receiving the information, Information can be received from the base station. This is effective for a person who provides local information because there is a possibility that local information can be provided to more users. However, on the other hand, even if the user does not want to receive the information, the wireless terminal receives the information broadcast by the wireless base station. This causes a problem that the wireless terminal wastes battery and storage capacity.

An example of the configuration and operation of a conventional wireless terminal will be described with reference to FIGS. 25 and 26. FIG.
Is a block diagram showing an example of a conventional wireless terminal, and shows a configuration example of a wireless terminal capable of receiving distribution information transmitted by a wireless base station. FIG. 26 is a flowchart showing an example of the operation of the conventional wireless terminal.

[0005] The radio terminal 1001 includes a receiving section 1002 for receiving control information transmitted by radio from the radio base station and distribution information transmitted from the radio base station;
And a reception control unit 1003 for controlling
In addition to these, the information processing system may include an information storage unit 1004 for storing information and the like received by the reception unit 1002.

The receiving unit 1002 of the wireless terminal 1001 receives control information broadcasted by the wireless base station by radio, and the receiving control unit 1003 determines whether the wireless base station can receive the control information, for example. It can be determined whether or not the distribution information transmitted by the station can be received (step S1011). If it is determined that the distribution information can be received, the reception control unit 1003 controls the reception unit 1002 to receive the distribution information transmitted by the wireless base station. When the reception unit 1002 receives the distribution information, The information storage unit 1004 stores the received distribution information (step S1012).

Here, for example, only the radio base station installed in the specific area transmits the area information to be distributed locally, such as an advertisement for a specific area or information limited to the area, to the radio terminal. A radio communication system for broadcasting, that is, a system in which a radio base station broadcasts different distribution information for each region will be considered. In this case, the wireless terminal 1001 of the user who stays in a certain area always receives and stores the distribution information while being able to receive from the wireless base station transmitting the distribution information. If the time is not updated, the information storage unit 10 in the wireless terminal 1001 is used to repeatedly receive and store the same distribution information.
04 and batteries are wasted. Such a problem may also occur in a wireless terminal of a user who repeatedly enters and exits a certain area in a short time as compared with a time interval at which distribution information is updated. In addition, the wireless terminal receives distribution information that the user does not want, or the wireless terminal receives local advertisement information that is completely unrelated to the user, thereby reducing the usability of the wireless terminal for the user. Also occurs.

In the above, a description has been given of a radio communication system in which a radio base station broadcasts distribution information. However, in a radio communication system in which a radio base station transmits distribution information to a radio terminal based on a request from the radio terminal. A similar problem arises. For example, there is a problem that the wireless terminal frequently requests the delivery information even though the delivery information is not updated, and repeatedly receives and stores the same delivery information. As a result, there arises a problem that the usability of the wireless terminal of the user is reduced and the wireless resource is wastefully used.

[0009]

As described above,
Conventionally, in a wireless terminal having a function of receiving distribution information from a wireless base station, there is a problem that received and stored distribution information is received and stored in an overlapping manner, or distribution information that is not desired is received and stored.

[0019]

Embodiments of the present invention will be described below with reference to the drawings.

(First Embodiment) The present embodiment will be described with reference to FIGS. 1, 2, and 3
Is a block diagram showing each configuration example of the wireless terminal according to the present embodiment, when receiving distribution information including content information and its attributes from the wireless base station, the terminal and its own terminal 5 shows a configuration example of a wireless terminal that determines whether to store the distribution information by comparing with an attribute. FIGS. 4, 5, and 6 are flowcharts each illustrating an operation example of the wireless terminal according to the present embodiment.

First, the distribution information transmitted by the radio base station will be described.

In this embodiment, it is assumed that the radio base station wirelessly broadcasts distribution information including at least content information and a content information attribute indicating the attribute of the content information. That is, it is assumed that the wireless base station transmits the distribution information so that all the wireless terminals that can receive the information from the wireless base station can receive the information.

As the content information attribute, it is possible to indicate the terminal attribute of the wireless terminal that should receive the content information transmitted by the wireless base station. For example, personal information (for example, age, gender, address, occupation, hobby, taste, etc.) of a user of a wireless terminal to receive content information can be indicated as a content information attribute. It is also possible to indicate the movement history of the wireless terminal that should receive the content information as a content information attribute. Further, the communication history of the wireless terminal that should receive the content information can be indicated as a content information attribute.

Further, it is possible to instruct the radio terminal which has received the content information, on the content information attribute, an operation to be performed on the content information. For example, an instruction regarding the deletion of the content information, for example, an instruction to delete the content information when a predetermined time has elapsed since the reception of the content information, or accumulation in a predetermined buffer of the information storage unit in the wireless terminal When the content information exceeds a predetermined amount and becomes the oldest of these, an instruction is given to delete the content information.

Next, the configuration of the wireless terminal will be described.

As shown in FIG.
Is a receiving unit 102 that receives distribution information, a terminal attribute storage unit 104 that stores terminal attributes of its own terminal, a receiving unit 102
An information storage unit 103 for storing the distribution information received (of which is determined to be stored), and a terminal attribute storage unit 1
An information storage control unit 105 that compares the terminal attribute stored in the storage unit 04 with the content information attribute included in the distribution information received by the receiving unit 102 and determines whether to store the distribution information. At least.

The terminal attribute storage unit 104 can store, for example, personal information (eg, age, gender, address, occupation, hobby, taste, etc.) of the user of the wireless terminal 101 as a terminal attribute. It is. In addition, the wireless terminal 1
It is also possible to store the movement history of No. 01 (for example, the time when the wireless terminal was present in the predetermined area, the existence time, etc.). It is also possible to store the communication history of the wireless terminal 101 (for example, the time, time, frequency, etc., when the user of the wireless terminal has accessed the predetermined information).

As shown in FIG. 2, it is also possible to include a terminal attribute control unit 106 capable of writing terminal attributes in the terminal attribute storage unit 104.

Further, as shown in FIG. 3, it is also possible to include a terminal attribute transmitting section 107 for transmitting the terminal attributes stored in the terminal attribute storing section 104 via a network at a predetermined timing. . Here, terminal attribute transmitting section 107 does not need to be connected to the same network as receiving section 102. For example, the receiving unit 102 may receive the data via a multimedia mobile access (MMAC) system, and the terminal attribute transmitting unit 107 may transmit the data via a PHS.

Although FIG. 3 shows the case where the terminal attribute control unit 106 and the terminal attribute transmitting unit 107 are included, it is needless to say that a configuration including the terminal attribute transmitting unit 107 without the terminal attribute control unit 106 is also possible. It is.

Next, the wireless terminal 1 configured as described above
The operation example of No. 01 will be described with reference to FIG. 4, FIG. 5, and FIG.

First, an example of an operation when receiving distribution information will be described with reference to FIG.

When the receiving unit 102 of the wireless terminal 101 receives the distribution information broadcasted by the radio base station by radio (step S111), the information storage control unit 105 stores the content information attribute and the terminal attribute storage included in the distribution information. A comparison is made with the terminal attributes stored in the unit 104 to determine whether or not the distribution information should be stored (step S112). If it is determined that the distribution information is not stored, the receiving unit 102
Waits until distribution information is received (step S11).
1). On the other hand, when it is determined that the distribution information is to be stored, the information storage unit 103 stores the distribution information. Note that only the content information of the distribution information may be stored.

Here, the case of controlling the reception and storage of the distribution information according to the user profile of the user of the wireless terminal will be described more specifically by way of example.

The radio base station indicates the age, gender, address, occupation, hobby, preference, etc. of the user of the radio terminal to receive the content information as a content information attribute, and associates the content information with the content information attribute. Broadcast as distribution information. On the other hand, the wireless terminal 10
The terminal attribute storage unit 104 in 1 stores the age, gender, address, occupation, hobbies, preferences, and the like of the user of the wireless terminal 101 as terminal attributes. When the wireless terminal 101 receives the distribution information, the information storage control unit 105 compares the content information attribute with the terminal attribute to determine whether the content information should be stored. For example, when a content information attribute indicating "male in the thirties" is designated, a wireless terminal in which "age" and "sex" corresponding to a male in the thirties are stored as the terminal attributes Stores the content information,
A wireless terminal storing information other than this as a terminal attribute discards the content information without storing it.

For example, if skiing is specified as a hobby as a content information attribute, a wireless terminal storing ski as a hobby as a terminal attribute stores the content information, and the wireless terminal stores the content information as a terminal attribute. A wireless terminal in which such information is not stored discards without storing the content information.

Further, as another example, a case will be described where a wireless terminal deletes received content information based on an instruction from a wireless base station.

The radio base station indicates, as a content information attribute, a method by which the radio terminal 101 that has received the content information deletes the content information, and broadcasts the content information and the content information attribute as distribution information. On the other hand, the wireless terminal 101 receives the distribution information, and the information storage unit 103 stores the distribution information.
The information storage control unit 105 recognizes the content information attribute and deletes the content information according to the method specified by the content information attribute. For example, if the content information that is specified to be deleted one hour after reception as the content information attribute is stored,
The information storage control unit 105 deletes the content information when one hour elapses after the reception. When the content information specified to be deleted at 6:00 am is stored as the content information attribute, the information storage control unit 105 deletes the content information when it reaches 6:00 am. Further, when the content information instructed to be deleted based on the amount of the buffer in the information storage unit 103 is stored as the content information attribute, the information storage control unit 105 stores the content information in a predetermined buffer in the information storage unit 103, When the total capacity or the total number of content information exceeds a predetermined value and the content information becomes the oldest content information, the content information is deleted. In the case of information such as a weather forecast, the content information attribute indicates that the information is deleted when the same information is newly received. In this case, even if the wireless terminal has already stored the weather forecast information in the information storage unit 103, if the wireless terminal newly receives the weather forecast information, the wireless terminal stores the weather forecast information stored in the information storage unit 103. Is deleted, and the information storage unit 103 stores the newly received weather forecast information.

By the way, the terminal attributes stored in the terminal attribute storage unit 104 in the wireless terminal 101 can be changed at any time. This operation example will be described with reference to FIG.

The terminal attribute control unit 106, for example, monitors the information storage unit 103, and manages operations performed by the user of the wireless terminal 101 on each piece of content information in the information storage unit 103. Here, the operation is, for example, whether or not the content information is displayed, whether or not the content information is heard, the number of times the content information is displayed, the number of times the content information is heard, and the like. Also, if the content information includes a telephone number of the inquiry destination, an e-mail address, an access destination address for more detailed information, etc., whether or not the access to these telephone numbers and addresses has been made, It is also possible to manage the number of accesses and the like.

The terminal attribute control unit 106 performs such management (for example, weighted addition may be performed in accordance with the content of the operation for each piece of preference information) to use the wireless terminal 101. Information of the user can be known. When it is determined that such preference information has changed (step S121), the terminal attribute storage unit 1
The terminal attribute in the terminal 04 is updated (step S122).

As another example, the terminal attribute control unit 1
06 monitors the receiving unit 102, for example, and
It is also possible to determine the terminal attribute using the movement history of the user 01. For example, when the receiving unit 102 receives a signal from a wireless base station installed in a ski resort between December and March, the terminal attribute control unit 106 accesses the terminal attribute storage unit 104 and sets The wireless terminal 1
01 is to be a hobby of skiing. Note that a method of obtaining the correspondence between the wireless base station and the attribute information such as skiing is, for example, preparing a correspondence table between the base station identifier and the attribute information in the terminal or the like, and also using the received base station identifier. And a method of referring to the correspondence table to obtain the corresponding attribute information, a method of describing the attribute information in a beacon message transmitted by the wireless base station, and the like.

According to the above operation, for example, when a radio base station installed at a station near the fashion building is broadcasting advertisement information of a bargain performed by the fashion building, it is operated from 7:00 to 9:00 in the morning. The wireless terminal owned by a woman over the age of 40 who has passed near the wireless base station during this period can selectively receive and store. Also, for example, when a wireless base station installed at a station near a ski equipment store broadcasts advertising information for a ski equipment store,
When a wireless terminal of a user who has gone to a ski resort from December to March passes near the wireless base station, the user can selectively receive and store the advertisement information of the ski accessory store. It becomes possible.

Further, it is also possible to transmit the terminal attributes as described above via a network. This operation example will be described with reference to FIG.

The terminal attribute transmitting unit 107 monitors whether the user of the wireless terminal transmits information (step S131). When transmitting the information, the user further determines whether to transmit the terminal attributes stored in the terminal attribute storage unit 104 in the wireless terminal 101 (step S132). If it is determined that the terminal attribute is to be transmitted, the terminal attribute transmitting unit 107 transmits the terminal attribute to a predetermined destination. For example, when the terminal attribute changes, the terminal attribute is transmitted periodically. With such an operation, the user of the wireless terminal transmits information at the same time that the terminal attribute storage unit 104 transmits information without wasteful transmission.
Can be transmitted to a predetermined destination. Further, it becomes possible for the network side to collect terminal attributes of each wireless terminal.

The present invention is also applicable to a system in which a radio base station transmits distribution information based on a request from a radio terminal.

As described above, even when the radio base station broadcasts the distribution information, the transmitter of the distribution information selectively transmits to the radio terminal desired as the destination by the radio terminal of the present invention. Transmission information can be transmitted. On the other hand, the wireless terminal can selectively receive only the distribution information that the user of the wireless terminal desires to receive. In addition, it is possible for the wireless terminal itself to determine what operation the user has performed on each piece of distribution information, or a user profile such as user preference information of the wireless terminal. Occurs, it is possible to adaptively change the distribution information selectively received by the wireless terminal. Also,
It is possible to transmit the preference information and the like of the user of the wireless terminal to the network at the same time as the user performs communication, and it is not necessary to perform the operation of transmitting the information only for transmitting the preference information and the like. Further, since the preference information and the like can be transmitted to the network as described above, it becomes possible for the information provider and the communication carrier to collect user profiles such as the preference information of the user of each wireless terminal. It is also possible to know what operation the user has performed on the individual distribution information. Further, the wireless terminal can delete the distribution information received from the wireless base station by a method instructed by the wireless terminal. From these facts, an easy-to-use wireless terminal can be realized for both the side providing the distribution information and the user of the wireless terminal receiving the distribution information.

(Second Embodiment) This embodiment will be described with reference to FIGS. FIG. 7 is a block diagram illustrating an example of the wireless terminal according to the present embodiment. The wireless terminal, which has received and stored distribution information within a predetermined time in the past, has a wireless terminal that prevents receiving the distribution information, An example of the configuration is shown. FIG. 8 shows a second example of the wireless terminal of the present embodiment.
FIG. 4 is a diagram showing an example of a storage form of information in an information storage unit of FIG. FIG. 9 is a flowchart illustrating an example of the operation of the wireless terminal according to the present embodiment.

In the present embodiment, it is assumed that the wireless base station wirelessly transmits the distribution information and wirelessly transmits a base station identifier for identifying itself. Here, the wireless base station may broadcast the distribution information to all wireless terminals that can receive the distribution information from the own station, or may transmit the distribution information based on a request from the wireless terminal. Is also good.

First, the configuration of the wireless terminal will be described.

As shown in FIG. 7, the wireless terminal 201
Is a receiving unit 202 for receiving a base station identifier and distribution information.
A reception control unit 203 that controls the reception unit 202; a first information storage unit 204 that stores distribution information received by the reception unit 202; a reception time when the reception unit 202 receives the distribution information; A second information storage unit 205 that stores the information in association with the base station identifier of the wireless base station that has transmitted the information. In addition, the first information storage unit 204 and the second information storage unit 205 may be configured separately or may be configured integrally.

The reception control unit 203 includes a second information storage unit 2
The receiving unit 202 is instructed to stop receiving distribution information from a wireless base station having the same base station identifier until a predetermined time has elapsed from the reception time stored in the reception time 05. Note that the second information storage unit 205
As shown in FIG. 8, the base station identifier of the radio base station that has received the distribution information and the reception time at which the distribution information has been received from each radio base station are stored. Note that the method of expressing the base station identifier and the reception time may be a method other than that shown in FIG.

Next, the wireless terminal 2 configured as described above
01 will be described with reference to FIG.

The receiving section 202 of the radio terminal 201 periodically receives control information broadcasted by the radio base station by radio, and the reception control section 203 controls the base station assigned to the radio base station included in the control information. Recognizing the station identifier, it is determined whether or not the mobile terminal has moved to a location where distribution information can be received from the wireless base station (step S211). This is based on, for example, the base station identifier and control information recognized by the reception control unit 203.
It is possible to determine whether distribution information can be received from the wireless base station.

In step S211, the reception control unit 20
If it is determined that the base station identifier has received the base station identifier of the wireless base station capable of receiving the distribution information, it is determined whether the base station identifier is already stored in the second information storage unit 205 (step S212). . Then, the reception control unit 203
If it is determined that the base station identifier is not stored in the second information storage unit 205, the receiving unit 202 is instructed to receive the distribution information (step S214), and the first information storage is performed. It instructs unit 204 to store the distribution information (step S214), and instructs second information storage unit 205 to store the base station identifier and the reception time (step S215). Thereafter, an operation of determining whether to receive a base station identifier of a wireless base station capable of receiving distribution information (step S2)
Return to 11).

On the other hand, if the reception control unit 203 determines in step S211 that the base station identifier of the wireless base station capable of receiving the distribution information has not been received, the base station identifier of the wireless base station capable of receiving the distribution information is determined. The operation of determining whether or not to receive (Step S211) is repeated. If the reception control unit 203 determines in step S212 that the base station identifier is stored in the second information storage unit 205, the base station identifier stored in the second information storage unit 205 It is determined whether or not a predetermined time has elapsed from the reception time when the distribution information was received from the wireless base station having the identifier (step S213). Here, the reception control unit 203
However, if it is determined that the predetermined time has not elapsed from the reception time, the operation of determining whether or not the base station identifier of the wireless base station capable of receiving the distribution information has been received (step S
211) is performed.

On the other hand, when the reception control unit 203 determines that a predetermined time or more has elapsed from the reception time, the reception unit 2
02 is received for distribution information (step S214).
And instruct the first information storage unit 204 to store the distribution information (step S214), and further instruct the second information storage unit 205 to store the base station identifier and the reception time. Store (Step S21)
5). That is, the second information storage unit 20
5 rewrites the reception time of the distribution information from the wireless base station having the base station identifier. Thereafter, the process returns to the operation of determining whether or not to receive the base station identifier of the wireless base station capable of receiving the distribution information (step S211).

The above-mentioned predetermined time may be determined uniformly, may be determined according to the attribute of the distribution information, may be determined according to the update cycle of the distribution information, or may be determined when the distribution information is transmitted. May be determined for each base station identifier of the wireless base station to be performed, a predetermined time may be described in the distribution information, and there are various other methods. This point is the same in other embodiments.

As described above, when the wireless terminal of the present invention receives and stores distribution information from a wireless base station, it stores the base station identifier of the wireless base station and the reception time, and a predetermined time from the reception time. Until the elapse, the distribution information transmitted by the wireless base station is not received. Therefore, in a wireless system in which a wireless base station transmits distribution information unique to the wireless base station, when a wireless terminal stays for a long time in an area covered by the same wireless base station, or when the same wireless base station covers Even when entering and exiting the area frequently, it prevents the wireless base station from repeatedly receiving the distribution information transmitted by the radio base station, and if the time interval at which the distribution information is updated is long, wasting the battery of the wireless terminal, It is possible to prevent waste of storage capacity and the like. For example, when a wireless base station that broadcasts distribution information that is updated every morning is installed at a railway station, the user does not need to receive the distribution information received at the station in the morning when the user passes through this station at night. In this way, it is possible to prevent the wireless terminal from repeatedly receiving and storing distribution information of the same content that has not been updated, thereby improving the usability of the user of the wireless terminal.

(Third Embodiment) This embodiment will be described with reference to FIGS. 7, 8, and 10. FIG. FIG. 7 is a block diagram illustrating an example of a wireless terminal according to the present embodiment, which receives distribution information from a wireless base station in the vicinity of a wireless base station that has received and stored distribution information within a predetermined time in the past. 1 shows a configuration example of a wireless terminal that prevents the occurrence of a call. FIG.
FIG. 3 is a diagram illustrating an example of a storage form of information in a second information storage unit of the wireless terminal according to the embodiment. Further, FIG.
5 is a flowchart illustrating an example of an operation of the wireless terminal according to the present embodiment.

The configuration of the wireless terminal is almost the same as that of the wireless terminal of the second embodiment. However, in the present embodiment, the reception control unit 203 sets the radio base station having the base station identifier and the radio base station until the predetermined time elapses from the reception time stored in the second information storage unit 205. Is instructed to stop receiving distribution information from a nearby wireless base station.

Next, the wireless terminal 2 configured as described above
01 will be described with reference to FIG.

The receiving section 202 of the radio terminal 201 periodically receives control information broadcasted by the radio base station by radio, and the reception control section 203 transmits the base station assigned to the radio base station included in the control information. Recognizing the station identifier, it is determined whether or not the mobile terminal has moved to a place where distribution information can be received from the wireless base station (step S221). This is based on, for example, the base station identifier and control information recognized by the reception control unit 203.
It is possible to determine whether distribution information can be received from the wireless base station.

In step S221, the reception control unit 20
3 has determined that the base station identifier of the wireless base station capable of receiving the distribution information has been received, the base station identifier or the base of the wireless base station existing in the vicinity of the wireless base station having the base station identifier If the station identifier is already in the second information storage unit 205
Is determined (step S222). If the reception control unit 203 determines that these base station identifiers are not stored in the second information storage unit 205, the reception control unit 203 receives the distribution information from the reception unit 202 (step S224). At the same time, the first information storage unit 204 is instructed to store the distribution information (step S224), and the second information storage unit 20
5 is instructed to store the base station identifier and the reception time (step S225). Thereafter, the process returns to the operation of determining whether or not the base station identifier of the wireless base station capable of receiving the distribution information has been received (step S221).

On the other hand, if the reception control unit 203 determines in step S221 that the base station identifier of the wireless base station capable of receiving the distribution information has not been received, the base station identifier of the wireless base station capable of receiving the distribution information is determined. The operation of determining whether or not to receive (Step S221) is repeated. In addition, in step S222, the reception control unit 203 stores the base station identifier or the base station identifier of a wireless base station existing near the wireless base station having the base station identifier in the second information storage unit 205. When it is determined, it is determined whether or not a predetermined time has elapsed from the reception time of receiving the distribution information from the wireless base station having the base station identifier stored in the second information storage unit 205 (step S22
3). Here, when the reception control unit 203 determines that the predetermined time has not elapsed from the reception time, an operation of determining whether a base station identifier of a wireless base station capable of receiving distribution information has been received is performed. (Step S221) is performed.

On the other hand, if the reception control unit 203 determines that a predetermined time has passed from the reception time, the reception unit 203
02 is received for distribution information (step S224).
And instruct the first information storage unit 204 to store the distribution information (step S224), and further instruct the second information storage unit 205 to store the base station identifier and the reception time. Store (Step S22)
5). That is, the second information storage unit 20
5 stores (or rewrites) the reception time of the distribution information from the wireless base station having the base station identifier. Thereafter, the process returns to the operation of determining whether or not the base station identifier of the wireless base station capable of receiving the distribution information has been received (step S221).

As described above, when the wireless terminal of the present invention receives and stores distribution information from a wireless base station, it stores the base station identifier of the wireless base station and the reception time, and a predetermined time from the reception time. Until the elapse, the distribution information transmitted by the wireless base station and the neighboring wireless base stations will not be received. Therefore, in a wireless system in which a plurality of wireless base stations in the area transmit distribution information specific to the area for each predetermined area, when the wireless terminal stays in the area for a long time, Even if the user frequently enters and exits the area, it prevents the wireless base station in the predetermined area from repeatedly receiving the transmission information, and when the time interval at which the distribution information is updated is long, the wireless terminal Battery waste,
It is possible to prevent waste of storage capacity and the like. For example, when a wireless base station that broadcasts distribution information that is updated every morning is installed at a railway station, the user does not have to receive the distribution information received at the station in the morning when the user passes through the station at night. Also, even when the same distribution information is transmitted at the wireless base station at the station next to the station used by the user, the same distribution information need not be repeatedly received. In this way, it is possible to prevent the wireless terminal from repeatedly receiving and storing the distribution information that has not been updated, and to improve the usability of the user of the wireless terminal.

(Fourth Embodiment) This embodiment will be described with reference to FIGS. 7, 11, and 12. FIG. FIG.
FIG. 3 is a block diagram illustrating an example of a wireless terminal according to the present embodiment, in which distribution information is received from a wireless base station belonging to the same area as a wireless base station that has received and stored distribution information within a predetermined time in the past. 1 shows a configuration example of a wireless terminal that prevents the occurrence of a call. FIG. 11 is a diagram illustrating an example of information storage in the second information storage unit of the wireless terminal according to the present embodiment. FIG. 12 is a flowchart illustrating an example of the operation of the wireless terminal according to the present embodiment.

In this embodiment, it is assumed that the same area identifier is assigned to a plurality of radio base stations belonging to a certain area.

Here, an example will be described in which the radio base station transmits the distribution information by radio and transmits the area identifier assigned to itself by radio.

The radio base station may broadcast the distribution information to all radio terminals that can receive the distribution information from the radio base station, or may transmit the distribution information based on a request from the radio terminal. There may be.

The configuration of the wireless terminal is almost the same as the wireless terminal of the second embodiment. However, in the present embodiment, the second information storage unit 205 stores, as shown in FIG.
The area identifier of the area to which the wireless base station that received the distribution information belongs and the reception time at which the distribution information was received from the wireless base station that belongs to the area are stored. Note that a method other than that shown in FIG. 11 may be used to represent the area identifier and the reception time. Further, in the present embodiment, the reception control unit 203 transmits the distribution information from the radio base station belonging to the area of the area identifier until a predetermined time elapses from the reception time stored in the second information storage unit 205. The receiving unit 202 is instructed to stop receiving.

Next, the wireless terminal 2 configured as described above
01 will be described with reference to FIG.

The receiving section 202 of the radio terminal 201 periodically receives control information broadcasted by the radio base station by radio, and the reception control section 203 includes an area assigned to the radio base station included in the control information. Recognizing the identifier, it is determined whether or not the mobile terminal has moved from a wireless base station capable of receiving the distribution information to a place capable of receiving the distribution information (step S231). For example, it is possible to determine whether or not distribution information can be received from the wireless base station based on the area identifier and the control information recognized by the reception control unit 203.

In step S231, the reception control unit 20
3 has determined that it has moved to a place where it can receive distribution information from a wireless base station that can receive the distribution information, the area identifier of the area to which the wireless base station belongs is already stored in the second information storage unit 2.
05 (step S23).
2). If the reception control unit 203 determines that the area identifier is not stored in the second information storage unit 205, it instructs the reception unit 202 to receive the distribution information (step S234). At the same time, it instructs the first information storage unit 204 to store the distribution information (step S234), and further stores the area identifier and the reception time in the second information storage unit 205 (step S235). ). Thereafter, the process returns to the operation of determining whether or not the mobile terminal has moved from a wireless base station capable of receiving the distribution information to a place where the distribution information can be received (step S231).

On the other hand, when the reception control unit 203 determines in step S231 that the distribution information cannot be received, it determines whether or not the user has moved from a wireless base station that can receive the distribution information to a place where the distribution information can be received (step S231). It returns to step S231). In step S232, the reception control unit 203
Determines that the area identifier is stored in the second information storage unit 205, the radio base station belonging to the area of the area identifier stored in the second information storage unit 205 It is determined whether or not a predetermined time has elapsed from the reception time at which the distribution information was received (step S23).
3). If the reception control unit 203 determines that the predetermined time has not elapsed from the reception time, the reception control unit 203 determines whether the user has moved to a place where the distribution information can be received from a wireless base station that can receive the distribution information. The operation returns to step S231.

On the other hand, if the reception control unit 203 determines that a predetermined time or more has elapsed from the reception time, the reception unit 203
02 is received (step S234).
And instructs the first information storage unit 204 to store the distribution information (step S234), and further stores the area identifier and the reception time to the second information storage unit 205. (Step S23)
5). That is, the second information storage unit 20
5 stores (or rewrites) the reception time of the distribution information from the wireless base station belonging to the area of the area identifier. Thereafter, the process returns to the operation of determining whether or not the mobile terminal has moved from a wireless base station capable of receiving the distribution information to a place where the distribution information can be received (step S231).

Note that such movement between areas can be recognized by a method other than the above. For example, a method in which a wireless terminal stores each area identifier and a base station identifier of a wireless base station belonging to each area, and obtains an area identifier from the base station identifier broadcast by the wireless base station on a control channel But it is possible.

Further, in this embodiment, a configuration for storing both the area identifier and the base station identifier, a configuration for storing only the area identifier, a configuration for storing only the base station identifier and obtaining the area identifier from the base station identifier when necessary. Both are possible.

As described above, upon receiving and storing the distribution information from the radio base station, the radio terminal of the present invention stores the area identifier and the reception time of the area to which the radio base station belongs, and Until a predetermined time has elapsed, the distribution information transmitted by the wireless base station belonging to the area is not received. Therefore, in a wireless system in which a plurality of wireless base stations in the area transmit distribution information specific to the area for each predetermined area, when the wireless terminal stays in the area for a long time, Even when entering and exiting the area frequently, it prevents repeated reception of the same distribution information transmitted by the wireless base station in the predetermined area, and when the time interval at which the distribution information is updated is long,
It is possible to prevent waste of battery and storage capacity of the wireless terminal. For example, when a wireless base station that broadcasts distribution information that is updated every morning is installed at a railway station, the user does not need to receive the distribution information received at the station in the morning when the user passes through this station at night. Also, even when the same distribution information is transmitted at the wireless base station at the station next to the station used by the user, the same distribution information need not be repeatedly received.
In this way, it is possible to prevent the wireless terminal from repeatedly receiving and storing distribution information of the same content that has not been updated, thereby improving the usability of the user of the wireless terminal.

(Fifth Embodiment) This embodiment will be described with reference to FIGS. FIG. 13 is a block diagram illustrating an example of the wireless terminal according to the present embodiment.
When the wireless terminal receives the distribution information, if the same distribution information as the distribution information has been received and stored within a predetermined time in the past, the wireless terminal for preventing reception and storage of the distribution information An example of the configuration will be described. FIG. 14 is a diagram illustrating an example of a storage form of information in the information storage unit of the wireless terminal according to the present embodiment. FIG. 15 is a flowchart illustrating an example of the operation of the wireless terminal according to the present embodiment.

In this embodiment, it is assumed that the wireless base station wirelessly transmits distribution information including at least content information and an information identifier for identifying the content information.

First, the configuration of the wireless terminal will be described.

As shown in FIG.
Is a receiving unit 302 that receives distribution information;
The information storage control unit 303 that determines whether the received distribution information should be stored in the own terminal, the distribution information determined to be stored by the information storage control unit 303 among the distribution information received by the reception unit 302, and And an information storage unit 304 that stores a reception time at which the distribution information is received.

As shown in FIG. 14, the information storage unit 304 stores the information identifier of the received distribution information, the reception time, and the content information. Where the information identifier,
The method of expressing the reception time and the like may be a method other than that shown in FIG.

Next, the wireless terminal 3 configured as described above
01 will be described with reference to FIG.

The receiving section 302 of the wireless terminal 301 determines whether or not the wireless base station has received the distribution information transmitted by radio (step S311).

Here, the radio base station may broadcast the distribution information to all the radio terminals that can receive the radio information from the radio base station, or may transmit the distribution information to the radio terminal based on a request from the radio terminal 301. 301 may be transmitted. Further, the receiving unit 302 may receive only the information identifier included in the distribution information without receiving the entire distribution information.
The case where the entire distribution information is received will be described as an example.

If the receiving unit 302 recognizes that the distribution information has been received, the information storage control unit 303 checks whether the same information identifier as the information identifier included in the distribution information is stored in the information storage unit 304. (Step S3)
12).

If the same information identifier as that of the distribution information is not stored in the information storage unit 304, the information storage control unit 303 sends the information storage unit 304 the information identifier received by the receiving unit 302. Distribution information (step S31
4) and an instruction to store the reception time (step S315). That is, for example, as shown in FIG. 14, the information storage unit 304 stores the information identifier, the reception time, and the content information of the distribution information received by the reception unit 302 (steps S314 and S315).

On the other hand, when the same information identifier as that of the distribution information is stored in the information storage unit 304, the information storage control unit 303 stores the same information identifier stored in the information storage unit 304. The storage time of the distribution information having the identifier is confirmed to be stored, and it is determined whether or not a predetermined time has elapsed from the reception time (step S313). If it is determined that the predetermined time has not elapsed, the receiving unit 302 returns to the operation of determining whether the wireless base station has received the distribution information transmitted wirelessly (step S311).

On the other hand, if it is determined that the predetermined time has elapsed, the information storage control unit 303 sends the distribution information (step S314) received by the receiving unit 302 and the reception time (step S3) to the information storage unit 304. S315) is instructed to be stored. That is, for example, as shown in FIG. 14, the information storage unit 304 stores the information identifier, the reception time, and the content information of the distribution information received by the reception unit 302 (steps S314 and S315).

As described above, upon receiving and storing the distribution information from the radio base station, the radio terminal of the present invention stores at least the information identifier and the reception time included in the distribution information, and determines a predetermined time from the reception time. Until time elapses, the distribution information having the same information identifier as the information identifier is not stored. Therefore, it is possible to prevent the wireless terminal from repeatedly receiving and storing the same distribution information in a short time, and to prevent the storage capacity from being wasted when the time interval at which the distribution information is updated is long. It becomes possible. For example, when a wireless base station that broadcasts distribution information that is updated every morning is installed at each railway station, the user receives the distribution information received at the boarding station in the morning and passes through another station such as an adjacent station or an alighting station. You do not need to receive it. In this manner, the wireless terminal is prevented from repeatedly receiving and storing distribution information of the same content that has not been updated, and a wireless terminal that is easy to use for the user can be realized.

(Sixth Embodiment) This embodiment will be described with reference to FIGS. 13 to 15, similarly to the fifth embodiment. FIG. 13 is a block diagram illustrating an example of the wireless terminal according to the present embodiment. When the wireless terminal receives distribution information, the wireless terminal receives and stores the same distribution information within a predetermined time in the past. If so, receive the distribution information,
5 shows a configuration example of a wireless terminal that prevents storage. FIG. 14 is a diagram illustrating an example of a storage form of information in the information storage unit of the wireless terminal according to the present embodiment. FIG. 15 is a flowchart illustrating an example of the operation of the wireless terminal according to the present embodiment.

The configuration and operation of the wireless terminal of this embodiment are as follows.
Although the configuration and operation of the wireless terminal of the fifth embodiment are the same as those of the fifth embodiment, in the present embodiment, the wireless base station transmitting the delivery information to the wireless terminal 301 sends at least one or more pieces of delivery information to a predetermined Consider a case where transmission is repeated periodically in order.

In this case, the wireless terminal 301 operates as shown in FIG. 15, and when each piece of distribution information is received for the first time, the information storage unit 304 stores the distribution information (step S314) and further receives the information. The time is also stored (step S3
15). However, when the period of transmission of the distribution information by the wireless base station is exceeded, the wireless terminal 301 already stores each distribution information and receives the same distribution information a plurality of times in a short time. Here, by setting the timer value to a sufficiently long time, it is determined that the predetermined time has not elapsed from the reception time (step S313), and the distribution information and the reception time are not stored. Note that it is also possible to stop receiving the distribution information itself.

As described above, the wireless terminal according to the present embodiment has the same effect as the wireless terminal according to the fifth embodiment. Also, once the wireless terminal receives and stores the periodically transmitted distribution information, it is possible to prevent receiving and storing the same distribution information, and immediately after the wireless terminal becomes able to receive from a certain radio base station. , The distribution information is received and stored, and when the series of distribution information is completely received, the distribution information is not received and stored. Therefore, when the wireless terminal receives a series of distribution information, the reception can be started earlier compared to a case where the reception can be started only from the leading distribution information, for example, and it is necessary until the reception of the series of information is completed. Can be shortened. In addition, the receiving unit 30 also waits until the wireless terminal receives the first distribution information.
2 may need to perform reception, and in comparison with this case, the receiving unit 302 can shorten the entire operation time for receiving the distribution information and can also reduce the power consumption. Becomes

(Seventh Embodiment) The present embodiment will be described with reference to FIG. 16, FIG. 14, FIG. 17, and FIG. FIG. 16 is a block diagram illustrating an example of the wireless terminal according to the present embodiment. When the wireless terminal receives distribution information, the wireless terminal receives and stores the same distribution information within a predetermined time in the past. If so, an example of the configuration of a wireless terminal that prevents receiving and storing the distribution information will be described. Also,
FIG. 14 is a diagram illustrating an example of a storage form of information in the information storage unit of the wireless terminal according to the present embodiment. Further, FIG.
FIG. 18 is a flowchart illustrating an example of an operation related to storage of distribution information in the wireless terminal according to the present embodiment.
9 is a flowchart illustrating an example of an operation related to deletion of distribution information in the wireless terminal according to the present embodiment.

In this embodiment, it is assumed that the wireless base station wirelessly transmits distribution information including at least content information and an information identifier for identifying the content information.

First, the configuration of the wireless terminal will be described.

As shown in FIG. 16, the wireless terminal 321
Is a receiving unit 322 for receiving distribution information;
The information storage control unit 323 that determines whether the received distribution information should be stored in the own terminal, the distribution information determined to be stored by the information storage control unit 323 among the distribution information received by the reception unit 322, and An information storage unit 324 for storing the reception time at which the distribution information was received, and an information deletion unit 325 for deleting the distribution information stored in the information storage unit 324
And an information identifier storage unit 326 that stores an information identifier of at least a part of the distribution information received by the receiving unit 322.

As shown in FIG. 14, the information storage unit 324 stores the information identifier of the received distribution information, the reception time, and the content information. Where the information identifier,
The method of expressing the reception time and the like may be a method other than that shown in FIG.

Next, the wireless terminal 3 configured as described above
21 will be described with reference to FIGS. 17 and 18. FIG.

First, storage of distribution information in a wireless terminal will be described with reference to FIG.

The receiving section 322 of the radio terminal 321 determines whether or not the radio base station has received the distribution information transmitted by radio (step S341).

Here, the radio base station may broadcast the distribution information to all radio terminals receivable from the radio base station, or may transmit the distribution information based on a request from radio terminal 321. It may be transmitted to the wireless terminal 321. Further, the receiving unit 322 may receive only the information identifier included in the distribution information without receiving the entire distribution information,
Hereinafter, a case where the entire distribution information is received will be described as an example.

If the receiving unit 322 recognizes that the distribution information has been received, the information storage control unit 323 stores the same information identifier as the information identifier included in the distribution information in the information identifier storage unit 326. It is confirmed whether or not there is (step S342).

When the same information identifier as that of the distribution information is stored in the information identifier storage unit 326, the process for determining whether the distribution information is received without storing the distribution information is performed. Return (step S341).

On the other hand, when the same information identifier as that of the distribution information is not stored in the information identifier storage unit 326, the information storage control unit 323 sets the same information identifier as that contained in the distribution information. The identifier is the information storage unit 32
4 is checked (step S34).
3). When the information storage unit 324 does not store the same information identifier as the information identifier of the distribution information, the information storage control unit 323 sends the distribution information received by the receiving unit 322 to the information storage unit 324. Is stored (step S345), and further, the reception time is stored (step S346). That is, for example,
As shown in FIG. 14, the information storage unit 324 stores the information identifier of the distribution information received by the reception unit 322,
The reception time and the content information are stored (step S345, S
346).

On the other hand, when the information storage unit 324 stores the same information identifier as the information identifier of the distribution information,
The information storage control unit 323 confirms that the reception time of the distribution information having the same information identifier stored in the information storage unit 324 is stored, and determines whether or not a predetermined time has elapsed from the reception time ( Step S344). If it is determined that the predetermined time has not elapsed, the receiving unit 322 returns to the operation of determining whether the wireless base station has received the distribution information transmitted by radio (step S341).

On the other hand, when it is determined that the predetermined time has elapsed, the information storage control unit 323 instructs the information storage unit 324 to store the distribution information received by the receiving means 322 (step (S345), and further instruct to store the reception time (step S346). That is, for example, it is stored as shown in FIG.

Next, deletion of the distribution information of the wireless terminal 321 will be described with reference to FIG.

The information deletion unit 325 checks whether there is a request to delete the distribution information stored in the information storage unit 324 (Step S331). If there is no request, the procedure of 331 is repeated until the request occurs. If there is such a request, the information deletion unit 325 deletes the content information and the reception time of the distribution information requested to be deleted in the information storage unit 324 (step S332).

Further, it is determined whether or not the information identifier of the distribution information requested to be deleted is also deleted (step S33).
3). Here, for example, a method of storing the information identifier of the distribution information whose reception is to be rejected in the information identifier storage unit 326 is conceivable. In this case, the user of the wireless terminal 321 may set rejection of the distribution information for the wireless terminal 321. Further, when the user of the wireless terminal 321 performs some operation on the wireless terminal 321 to selectively delete the distribution information, the distribution information is received thereafter,
The information identifier of the distribution information may be stored in the information identifier storage 326 so as not to store it.

When the information deleting unit 325 determines that the information identifier of the distribution information requested to be deleted is also deleted, the information identifier is also deleted from the information storage unit 324 (step S334). On the other hand, if the information deletion unit 325 determines that the information identifier of the distribution information requested to be deleted is not deleted, the information identifier is deleted from the information storage unit 324, but the information identifier is deleted from the information identifier storage unit 326. (Step S335). In any case, the process returns to step S331.

As described above, the wireless terminal according to the present embodiment has the same effects as the wireless terminal according to the fifth embodiment.
Even if the information itself is deleted, by storing the information identifier, it is possible to prevent the wireless terminal from receiving and storing information that the user wants to refuse to receive or unnecessary information again.

(Eighth Embodiment) This embodiment will be described with reference to FIGS. FIG. 19 is a block diagram illustrating an example of a wireless terminal according to the present embodiment.
When the wireless terminal receives the distribution information, if the same distribution information as the distribution information has already been received and stored, an example of the configuration of the wireless terminal that prevents the reception and storage of the distribution information is shown. . FIG. 20 is a diagram illustrating an example of a storage mode of content information in the information storage unit of the wireless terminal according to the present embodiment. FIGS. 21 and 22 are flowcharts each showing an operation example of the wireless terminal in the present embodiment.

In this embodiment, it is assumed that the radio base station wirelessly transmits distribution information including at least content information and an information identifier for identifying the content information. In addition, the wireless base station transmitting the distribution information to the wireless terminal 401 may periodically and repeatedly broadcast at least one or more pieces of the distribution information in a predetermined order.

First, the configuration of the wireless terminal will be described.

[0120] As shown in FIG.
Is a receiving unit 402 that receives distribution information;
The information storage control unit 403 that determines whether the received distribution information should be stored in the own terminal, and stores the distribution information that is determined to be stored by the information storage control unit 403 among the distribution information received by the reception unit 402. Information storage unit 404,
The information storage unit 404 is configured to include at least an information deletion unit 405 for deleting distribution information stored therein.

As shown in FIG. 20, the information storage unit 404 stores an information identifier of the received distribution information and content information. Here, the information storage unit 404 may store information other than the information identifier and the content information.

Next, the wireless terminal 4 configured as described above
01 will be described with reference to FIGS. 21 and 22.

First, description will be made with reference to FIG.

The receiving section 402 of the wireless terminal 401 determines whether or not the wireless base station has received the distribution information transmitted by radio (step S411).

Here, the radio base station may broadcast the distribution information to all radio terminals receivable from the radio base station, or may distribute the distribution information based on a request from radio terminal 401. It may be transmitted to the wireless terminal 401. Also, the receiving unit 402 may receive only the information identifier included in the distribution information without receiving the entire distribution information,
Hereinafter, a case where the entire distribution information is received will be described as an example.

If the receiving unit 402 recognizes that the distribution information has been received, the information storage control unit 403 checks whether the same information identifier as the information identifier included in the distribution information is stored in the information storage unit 404. Confirmation (Step S4)
12).

When the same information identifier as that of the distribution information is stored in the information storage unit 404, the information storage control unit 403 discards the distribution information without storing the information.
The operation of waiting for the reception of the distribution information is continued (step S41).
1). On the other hand, when the same information identifier as the information identifier of the distribution information is not stored in the information storage unit 404, the information storage control unit 403 sends the distribution information received by the reception unit 402 to the information storage unit 404. It is instructed to store the information reception time. That is, for example, as shown in FIG. 20, the information storage unit 404 stores the information identifier and the content information of the distribution information received by the reception unit 402 (step S413).

Next, description will be made with reference to FIG.

On the other hand, the information deleting unit 405
It monitors whether or not there is a request to delete at least a part of the distribution information stored in the distribution information stored in the storage unit 04 (step S421). This deletion of the distribution information is instructed to be deleted by a request of the user of the wireless terminal and an operation on the wireless terminal, a deletion after a lapse of a predetermined time after receiving the distribution information, and a deletion of the distribution information. When the time reaches the time, when the information amount or the number of the received and stored distribution information as a whole exceeds a predetermined amount, the deletion due to the oldest distribution information may be considered. In addition,
As for such a condition for deleting the distribution information, the radio base station can indicate the deletion condition in the distribution information and transmit the same, thereby instructing the radio terminal of the deletion condition. When a deletion request for specific distribution information is generated, the information deletion unit 405 deletes the specific distribution information in the information storage unit 404 (Step S422). That is, the information identifier and the content information of the specific distribution information are deleted from the information storage unit 404.

As described above, upon receiving and storing the distribution information from the radio base station, the radio terminal of the present invention stores at least the information identifier and the content information included in the distribution information, and deletes the distribution information. Otherwise, the distribution information having the same information identifier as the information identifier is not stored. Therefore, it is possible to prevent the wireless terminal from repeatedly receiving and storing the same distribution information in a short time, and to repeatedly receive and store unnecessary information when the time interval for updating the distribution information is long. Therefore, it is possible to prevent waste of storage capacity and the like. For example, if a radio base station that broadcasts distribution information that is updated every morning is installed at each railway station, the distribution information received by the user at the station where the user gets on in the morning, as well as the next station and the It does not need to be received when passing through other stations such as a station. Further, when the radio base station notifies the radio terminal of the time at which the distribution information is updated as the time at which the distribution information is deleted, the radio terminal may receive and store the distribution information again until the distribution information is updated. Can be prevented, and the distribution information can be automatically received after the distribution information is updated. further,
When the wireless base station transmitting the distribution information to the wireless terminal 401 periodically broadcasts at least one or more pieces of distribution information in a predetermined order, the wireless terminal When receiving, there is no need to specify the reception start time of the wireless terminal, and the wireless terminal can start receiving from any distribution information. Therefore, the wireless terminal can receive and store the distribution information for one cycle in a shorter time, and the time required for the reception can be shortened, which leads to a reduction in power consumption. As mentioned above,
This prevents the wireless terminal from repeatedly receiving and storing distribution information of the same content that has not been updated, and also enables the latest distribution information to be received in accordance with the update of the distribution information. A terminal can be realized.

(Ninth Embodiment) This embodiment will be described with reference to FIGS. 19, 20, 23, 21, and 24. FIG. FIG. 19 is a block diagram illustrating an example of the wireless terminal according to the present embodiment. When the wireless terminal has received distribution information and has already received and stored the same information identifier as the distribution information, An example of the configuration of a wireless terminal that prevents reception and storage of the distribution information is shown (similar to the block diagram illustrating an example of the wireless terminal according to the eighth embodiment).
FIG. 20 is a diagram illustrating an example of a storage mode of content information in the information storage unit of the wireless terminal according to the present embodiment. FIG. 23 is a diagram illustrating an example of a storage form of the information identifier in the information storage unit of the wireless terminal according to the present embodiment. FIG.
1 and FIG. 24 are flowcharts each showing an operation example of the wireless terminal in the present embodiment.

In this embodiment, it is assumed that the radio base station wirelessly transmits distribution information including at least content information and an information identifier for identifying the content information. Further, the radio base station transmitting the distribution information to the radio terminal may periodically and repeatedly broadcast at least one or more pieces of distribution information in a predetermined order.

First, the configuration of the wireless terminal will be described.

As shown in FIG. 19, wireless terminal 401
Is a receiving unit 402 that receives distribution information;
The information storage control unit 403 that determines whether the received distribution information should be stored in the wireless terminal, and the distribution information determined to be stored by the information storage control unit 403 among the distribution information received by the reception unit 402. , An information storage unit 404 capable of storing the information identifier of the deleted distribution information, and an information deletion unit 405 configured to delete the content information and the information identifier stored in the information storage unit 404. .

As shown in FIG. 20, the information storage unit 404 stores the information identifier of the received distribution information and the content information. Further, as shown in FIG. 23, the information identifier of the deleted distribution information is stored. Here, the information storage unit 404 may store information other than the information identifier and the content information.

Next, the wireless terminal 4 configured as described above
01 will be described with reference to FIGS. 21 and 24.

First, description will be made with reference to FIG.

[0138] The receiving section 402 of the wireless terminal 401 determines whether or not the wireless base station has received the distribution information transmitted wirelessly (step S411).

Here, the radio base station may broadcast the distribution information to all radio terminals receivable from the radio base station, or may transmit the distribution information based on a request from radio terminal 401. It may be transmitted to the wireless terminal 401. Also, the receiving unit 402 may receive only the information identifier included in the distribution information without receiving the entire distribution information,
Hereinafter, a case where the entire distribution information is received will be described as an example.

If the receiving unit 402 recognizes that the distribution information has been received, the information storage control unit 403 checks whether the same information identifier as the information identifier included in the distribution information is stored in the information storage unit 404. Confirmation (Step S4)
12).

When the same information identifier as that of the distribution information is stored in the information storage unit 404, the information storage control unit 403 discards the distribution information without storing the information.
The operation of waiting for the reception of the distribution information is continued (step S41).
1). On the other hand, when the same information identifier as the information identifier of the distribution information is not stored in the information storage unit 404, the information storage control unit 403 sends the distribution information received by the reception unit 402 to the information storage unit 404. It is instructed to store the information reception time. That is, for example, as shown in FIG. 20, the information storage unit 404 stores the information identifier and the content information of the distribution information received by the reception unit 402 (step S413).

First, a description will be given with reference to FIG.

On the other hand, the information deleting unit 405
It monitors whether or not there is a request to delete at least a part of the distribution information among the distribution information stored in step 04 (step S431). This deletion of the distribution information is instructed to be deleted by a request of the user of the wireless terminal and an operation on the wireless terminal, a deletion after a lapse of a predetermined time after receiving the distribution information, and a deletion of the distribution information. When the time reaches the time, when the information amount or the number of the received and stored distribution information as a whole exceeds a predetermined amount, the deletion due to the oldest distribution information may be considered. In addition,
As for such a condition for deleting the distribution information, the radio base station can indicate the deletion condition in the distribution information and transmit the same, thereby instructing the radio terminal of the deletion condition. When a deletion request for specific distribution information is generated, the information deletion unit 405 deletes the specific content information in the information storage unit 404 (Step S432).

Next, the information deletion unit 405 determines whether or not to delete the information identifier of the deleted specific content information (step S433). Here, whether to delete the information identifier may be determined according to the reason why the deletion is requested.
For example, the information identifier is stored only in the case of deletion at the request of the user of the wireless terminal, and the information identifier is also deleted in the case where the information is deleted after a predetermined time has elapsed after receiving the distribution information. It is possible.

When it is determined that the information identifier is to be deleted, the information deletion unit 405 deletes the information identifier of the deleted content information in the information storage unit 404 (step S43).
4). On the other hand, when it is determined that the information identifier is to be stored, the information deletion unit 405 does not delete the information identifier of the deleted content information in the information storage unit 404 but keeps storing the information identifier (step S435). For example, the information storage unit 404
Stores the information identifier in a form as shown in FIG. 23 until a predetermined time elapses.

As described above, the wireless terminal according to the present embodiment differs from the wireless terminal according to the eighth embodiment in that, even when the distribution information is deleted, at least a part of the information identifier of the deleted distribution information is obtained. Can be stored. As a result, for example, it is possible to store only the information identifier of the distribution information that the user of the wireless terminal has requested to delete, and the distribution information or the like that the user intentionally deleted without matching the user's preference Can be prevented from being received and stored thereafter. On the other hand, other distribution information is deleted if it has been deleted due to exceeding the storage capacity, or if it has been deleted because more than a predetermined time has elapsed since it was received, if the distribution information has been updated since then, etc. Can be received and stored. As described above, the wireless terminal of the present invention stores the information identifier of the distribution information according to the reason for deletion or the like, so that it is possible to receive the distribution information according to the user's preference and intention, An easy-to-use wireless terminal can be realized.

Note that the first embodiment described above
The ninth embodiment can be implemented in any combination.
In addition, in the combined embodiment, when the conditions for enabling or disabling reception and storage conflict, the conditions may be logically ANDed and applied, or the conditions may be ORed and applied. Alternatively, it is also possible to apply by another logical combination.
