Description

LOCAL INFORMATION TRANSMISSION SYSTEM BACKGROUND OF THE INVENTION FIELD OF THE INVENTION The invention relates to an information receiver and method for receiving various information, and also to a system for transmitting and receiving information that receives by means of the information receiver various information transmitted from a transmitter.

BACKGROUND OF THE INVENTION In recent years, portable receivers and transmitters of information have proposed that an individual receives various information through a wireless call, radiolocation and wireless transmission. For example, among the portable information receivers are the so-called pagers, which allow receiving information distribution services such as weather forecasts and information about public events. Said information receivers receive transmissions from a prescribed base station that is within their coverage area. The reception area for wireless calls, radiolocation and wireless transmission has until now been covered by a set of approximately circular forms centered on base stations, and the range of coverage and the limit lines of the coverage area vary with the number of base stations , its power of transmission, and topography, resulting in the limits of the coverage area are generally uncertain. For example, as shown in Figure 1, the area designated by the number 1 to which a given base station can transmit is approximately circular in order to cover multiple areas. In this example, as shown in Figure 1, the three areas of city A, district B and zone C are included as the reception area covered by the base station X. In a case where reception area 1 has such a In the same way, due to the uniform radiation, the radio waves from the base station X are transmitted to the whole city A, district B and zone C even though the transmission is information that is only valid for district B. That is, the information for district B, even when it is not relevant for city A and zone C, is not restricted and is received in city A and zone C. Specifically, an explanation is given using figure 2. In this example , as shown in figure 2, the distribution area is covered by the three base stations D, E and F, and within this distribution area there are data collection lines G and H. The data collection line G is located within the distribution areas of base stations D and E, and the data collection line H within the distribution area of the base stations D and F. In such an area, if one wishes to distribute operating information for the data collection lines G and H, it can be done by the following methods of distribution. For example, the above operation information is the itinerary and the operating status. In the first distribution method, the information for both data collection lines G and H is distributed from all base stations D, E and F. In the second distribution method, the operation information for the data collection lines G and H is only distributed from the base station D, the operation information for the data collector line G is only distributed from the base station E, and the operation information for the data collector line H is only distributed from the base station F. However, in the first distribution method, the distribution area covered by the base station E is distributed operating information for the data collection line H that is irrelevant for that area, and the distribution area covered by the base station F is distributed operating information for the data collection line G which is irrelevant for this area. In the second distribution method, it is necessary to select, classify and handle the transmitting base stations in a flexible manner according to the content of the information.

In both, the first and second distribution method, the irrelevant information reaches areas outside of the areas near the data collection lines G and H (the areas within the dotted lines in Figure 2). As previously established, the reception area is covered by a set of approximately circular shapes centered around the base stations, and the range of coverage and limit lines of the coverage area vary depending on such factors as the number of base stations , its power of transmission, and topographic conditions, and in general the limit is uncertain. This leads to several local problems, including that the necessary information is not distributed, or that unnecessary information is distributed. And because the transmission infrastructure is largely determined by business conditions and legal regulations, there is also the problem of flexibility in the number of base stations and their transmission power in order to provide local distribution. In addition, the information that is required varies with the area, and if someone wishes to distribute the prescribed information only to a specified area, there is the operational problem of having to select and classify the base stations that will transmit any given information. On the other hand, although someone who receives irrelevant information can simply ignore it, a large volume of irrelevant information is inconvenient. As an extreme example, it would not be very useful to distribute local information to specified neighborhoods in Aomori (a prefecture in northeastern Japan) or Tokushima (a prefecture in southwestern Japan) when a nationwide channel broadcast is heard in Tokyo. In general, if one covers an area with a single base station, several areas are obtained where the irrelevant information is distributed in a high coverage infrastructure, and in a small coverage infrastructure, one must control the base stations in which it is located. transmit local information.

DETAILED DESCRIPTION OF THE INVENTION Next, a detailed description of one embodiment of the invention will be given, with reference to the accompanying drawings. In this embodiment, the information reception and transmission system of the present invention is applied to an information communication system that performs wireless communication or radiolocation. As shown in Figure 3, an information communication system 1 of this mode includes a base station 2 that transmits information and a receiver 3 that receives transmissions from the base station 2. In addition, the information reception system 1 adopts a configuration in which the receiver 3 receives satellite transmissions from a GPS satellite (global positioning system) 4 and measures its position. The receiver 3 includes a transmission reception antenna 11, a wireless transmission reception circuit 12, an operation unit 13, a position information fixing circuit 14, a GPS reception antenna 15, a reception circuit of GPS 16, and a discrimination processing unit 17. In receiver 3, discrimination processing unit 17 consists of a data separator / area ID 31, an area discriminator 32, a GPS decoder 33, an on / off gate 34, a receive decoder 35 and a system data bus 36.

The receiver 3, for example, can be a small portable locator.

Attached to the receiver 3 having said configuration are an image display device 21, a sound output device 22, and a peripheral input-output device 23. In the information communication system 1, the base station 2 is constituted by a transmission unit that is added to the area information that represents the absolute position to the main information and transmits it. In addition, the receiver 3 has a reception unit, an operation unit 13, a position information fixing circuit 14, a GPS reception antenna 15, a GPS reception circuit 16 and a GPS decoder 33 consisting of of a current position acquisition unit that acquires information on current position, i.e. information about the current position of someone; an area discriminator 32, which is a comparison unit that compares the current position of information with the area information; and a receiving decoder 35, which is a receiving processing unit that performs reception processing of the main data according to the results of the comparison by the area discriminator 32. The detailed description of the various parts forming the system The reception of information 1 is as follows: The wireless transmission reception circuit 12 receives wireless transmissions from the base station 2 through the transmission reception antenna 11. Here the transmission of information from the base station 2 is, for example , content information; to this content information is added the ID of the area to which it will be sent, according to the content. As shown in Figure 4, the transmission information 101 is formed into packets in information ID 102, area ID 103, and part of the data 104. In the data part 104 the main information that will be distributed is stored.; For example, the main information may be information about the weather. The information ID 102 indicates the nature of the main information stored in the data part 104; for example, if the weather information is stored in the data part 104, the information indicating that the main information is weather information is stored in the information ID 102. The area ID 103 indicates information about the weather. area to which the main information stored in data part 104 will be distributed; for example, if the meteorological weather information is stored in the data part 104, the area whose information on the weather will be displayed is stored in this area ID 103. That is, if for example it is information about the weather Shibuya (a neighborhood in Tokyo), an ID indicating Shibuya is in this area ID 103. The information 101 having said composition is received in the wireless transmission reception circuit 12 and is entered into the data separator / ID of area 31 of the discrimination processing unit 17. The data separator / area ID 31 extracts the area ID 103 that has been added to the main information and outputs it to the area discriminator 32. What is introduced in the discriminator of area 32 are the area data set arbitrarily from the terminal itself, the position measurement data output from the GPS decoder 33, or both. The area data arbitrarily set from the terminal refer to the data set in the position information fixing circuit 14 for the operation of the operation unit 13; that is, for example, the data set by the user as his current location. Here, the operation unit 13 and the position information fixing circuit 14 constitute a means of entry of current position that introduces the current position information. In addition, the established area is not limited to the current position but can be an arbitrary area, for example, the location to which the user intends to go. The data output of the position measurement from the GPS decoder 33 are data consisting of the current position, etc. obtained by recei a transmission signal from the GPS satellite 4 through the GPS reception circuit 16 through the GPS reception antenna . That is, here the GPS reception antenna 15, the GPS reception circuit 16 and the GPS decoder 33 comprise current position measuring means that measure the current position.

An arbitrary system other than GPS that can measure the current position, for example, PHS (personal telephony system) can also be used. The area discriminator 32 decides whether the data of the area established from the position information fixing circuit 14 and / or the position data from the GPS decoder 33 (referred to as current position data, hereinafter) coincide with the area ID of the data separator / area ID 31. Then, the on / off gate 34 is operated according to the result of this decision. That is, if the area ID and the current position data match, the on / off gate 34 is operated and the content data, i.e. the main information, passes to the receive decoder 35, and if the area ID and the current position data does not match, the on / off gate 34 closes, and the main information stops there. The receive decoder 35 decodes the received main information that was discriminated and entered as previously established. The main information decoded in the reception decoder 35 is emitted-processed to the outside by the data bus of the system 36. That is, depending on the application, etc., the main information is emitted as an image by the deployment device. 21 and is emitted as sound by the sound output device 22, while the processing of memory storage, alarm processing, etc., is performed by the peripheral input-output device 23. The following is a explanation of the parts of the information reception system 1. Figure 5 shows the series of steps performed by the receiver 3 to process the reception of the main information. As shown in Figure 5, in step S1, the receiver 3 receives the transmission of information in packets from the base station 2. In step S2, receiver 3 acquires data on current position. This current position data is either the area data set by position information set-up circuit 14, or the measured data obtained from the GPS set-top box 33, or both. Any of the steps S1 and S2 can be executed first. In step S3, receiver 3 separates the area ID from the information in packets it received. Then, in step S4, the receiver 3 compares the area ID of the received information and the current position data and decides whether they coincide. If the area ID of the received information and the current position data match, then the main information stored in the received packet is the necessary information, and if on the other hand they do not match, then the main information stored in the received packet is information unnecessary If they do not match, control proceeds to step S5, and processing is performed so that the information is not received. Specifically, the on / off composite 34 is turned off by a signal from the area discriminator 32. If, on the other hand, it is confirmed that the main information is a necessary information, the receiver 3 proceeds to step S6 and concludes the reception of data, which is the processing of reception of the main information. Specifically, the on / off gate 34 is turned on by a signal from the area discriminator 32, and the received information is processed by reception by the receiving decoder 35. Then the received signal is sent through the system data bus 36 to the image display device 21, sound output device 22, and peripheral input-output device 23, etc. This is, for example, an ID indicating an area such as "Shibuya" or "Ginza" (neighborhoods of Tokyo) is in the area ID 103 shown in Figure 4, the area ID is compared with the position information calculated by GPS, and the information corresponding to other locations different from those of someone in particular is discarded. In the information communication system 1, the receiver 3 receives the appropriate main information by discriminating the area information that is added to the main information that is transmitted from the base station 2. If an information communication system 1 of this is constructed Even if the relevant local information for each area is transmitted from an unspecified base station, it is arbitrarily taken or discarded at the receiving terminal, and only extremely useful information is automatically received and processed, such as deployment and storage. Therefore, a terminal at any location can receive only local information that is useful for that area, regardless of the conditions of the transmission infrastructure or the coverage status, which makes it more useful to receive information. This information communication system 1, maintains the general advantages of transmission use on the transmission side of the base station 2, while on the receiving side of the receiver 3 it has the advantages of narrow transmission, selecting exactly the information which is relevant to an area. The mode shows receiver 3 with dedicated circuits of each block, but unnecessary for parts other than analog circuits including the radio wave frequency circuit system can be realized by digital signal processing (DSP), "firmware" processing or by program processing of the central processing unit (CPU). The modality was described by adding an area as area information to the main information that will be distributed, but is not limited to it. For example, it is possible to represent many areas in the area information for each main information item. Specifically, by establishing multiple areas such as "Shibuya" and "Ginza" as area information, it is possible to communicate information that is useful for those areas, such as weather information for the region including Shibuya and Ginza. The information receiver of the present invention is not limited to its application to pagers. That is, the information receiver can be applied, for example, to a portable information communication terminal, a so-called personal digital assistant (PDA) that maintains the ability to be ported and provides information communication, organization and storage. The information receiver of the invention - by means of acquisition of current position that acquire information about current position, which is information about the current position of someone; a comparison means comparing the current position information and the area information; and a receiving processing measure that processes the reception in the main information according to the comparison results by the comparison means - compares by means of the comparison means the current position information acquired by the position acquisition means. Current and area information, and by the receiving processing means can process the reception on the main information according to the comparison results by the comparison means. This makes it possible for the receiver of information to receive selectively only the information relevant to his current position of various information that comes from multiple transmissions. The method of receiving information of the invention - having a current position acquisition step that acquires current position information, which is information about someone's current position; a comparison step that compares the current position information and the area information; and a receiving processing step that processes the reception of the main information according to the comparison results in the comparison step - compares in the comparison step the current position information acquired in the current position acquisition step with the area information, and in the reception processing step performs reception processing in the main information according to the comparison results in the comparison step. In this way, the method of receiving information selectively receives, from diverse information that comes from multiple transmissions, only information that is relevant to someone's current position. The system for receiving and transmitting information of the present invention - by means of transmission that are added to the main information, area information that expresses the absolute position of someone and transmits it, and receiving means having means of position acquisition current that acquires current position information, which is information about someone's current position; a comparison means comparing the current position information and the area information; a comparison means that compares the current position information, which is information about the current position of someone, with the received area information; and a receiving processing means that provides reception processing of the main information according to the comparison results by means of the comparison means - it can through transmission means add area information expressing the absolute position of someone to the information and transmitting it, and can with the receiving means compare the current position information acquired by the current position acquisition means and the area information received by the comparison means, and can by the processing means of receiving perform the processing of reception of the main information according to the results of the comparison by means of comparison. In this way, in the system of receiving and transmitting information, multiple information is transmitted by means of transmission, and the means of receiving information selectively receive, from diverse information that comes from multiple transmissions, only the information that is relevant for someone's current position.
