Description

  The present invention is a mobile phone system including a plurality of mobile phones, a mobile switching center for mobile phones, and various information providers connected to the mobile switching center. The present invention relates to a cellular phone system with a simultaneous transmission function for transmitting to a cellular phone.

Conventional information providing means for mobile phones is based on the following system.
1) On-demand type: The owner of the mobile terminal who wants to obtain information enters the ID number or password specified in advance using the mobile terminal and communicates wirelessly, and the information providing service company provides this ID. Authenticate as a registered user by number or password, and send the contents of the information to the user's mobile phone number.
2) Push type: An information provider calls a registered telephone number individually to a mobile phone user registered in advance, and stores the information content in the form of an incoming e-mail or the like in the memory of the mobile phone. Alternatively, simultaneous transmission is performed using a special wireless terminal for simultaneous transmission using a preset frequency for a specific user group. Voices etc. are sent by simultaneous transmission using the same frequency to areas with a small coverage area such as wireless terminals using low power.

  In the conventional on-demand type, when the owner of the mobile terminal requests information provision as necessary, the information provision service company provides the information accordingly, and it is used in advance that information is required It must be recognized by the person. However, urgent communication information, such as earthquakes, tsunamis, typhoons, etc., and instantly changing financial information, such as sudden ups and downs in stock prices, exchange rates, etc. It is rare to recognize when it is needed. For this purpose, a push-type information providing system is required.

  In addition, in the conventional on-demand type, a large amount of information is transmitted when there is a lot of radio waves because mobile phone users charge for normal mobile phone usage hours, and the radio waves become even more congested. This leads to increased congestion.

  Even in push-type distribution, when making a call to individual telephone numbers, the information provided must be sent to the user sequentially. If there are N recipients, the sending time will be sent. It takes N times as long as the number of the other party is one.

  The purpose of the present invention is to transmit information all at once, to transmit information over a wide range without being limited to the area, and with a simultaneous transmission function that can reduce the cost in inverse proportion to the number of users in the same wireless zone To provide a mobile phone system.

  The cellular phone system with simultaneous transmission function according to claim 1 is composed of a plurality of cellular phones, a portable switching center of the cellular phone, and various information providers connected to the portable switching center. The transmission destination information for simultaneous transmission is registered in the mobile phone and the mobile switching center, and one or a plurality of frequency information for the general communication within the mobile phone usage band allocated to the mobile phone carrier Specific frequency bands are allocated for simultaneous transmission, and the mobile switching center sends the information sent from the various information providers from each base station based on the destination information for simultaneous transmission. The simultaneous transmission is performed in the frequency band. As the transmission destination information for simultaneous transmission, for example, a common telephone number or a common ID number is used.

  Destination information for simultaneous transmission is registered in a plurality of mobile phones and a mobile switching center, and one or aside from the general communication frequency band in the mobile phone usage band allocated to the mobile phone carrier Multiple specific frequency bands are allocated for simultaneous transmission, and the mobile switching center transmits information sent from various information providers simultaneously from each base station in the specific frequency band based on the destination information for simultaneous transmission. Information can be transmitted all at once, and even when a mobile phone moves from one base station to another, there is no need to switch the frequency band for receiving information, and information can be transmitted over a wide area without being limited to a region. The cost required for providing information can be reduced in inverse proportion to the number of users.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram of a mobile phone system with a simultaneous transmission function (hereinafter simply referred to as a mobile phone system 1) according to the present embodiment. As shown in FIG. 1, the mobile phone system 1 is connected to a plurality of mobile phones 2, 2, 2..., A mobile switching center (mobile phone operator) 3 for the mobile phone 2, The various information providers 4 are configured. The portable switching center 3 mentioned here does not mean one portable switching center limited to one region, but represents the entire portable switching center of a mobile phone carrier. Each base station 5 a, 5 b, 5 c,... Is connected to the portable switching center 3, and each mobile phone 2 is wirelessly connected to each base station 5. FIG. 1 shows an example in which the mobile phone 2a is connected to the base station 5a by wireless communication, the mobile phone 2b is connected to the base station 5b by wireless communication, and the mobile phone 2c is connected to the base station 5c by wireless communication. Has been.

  The mobile switching center 3 is provided with a subscriber memory 6. The subscriber memory 6 includes transmission destination information (for example, common) for simultaneous transmission (for broadcast communication) to a plurality of mobile phones 2a, 2b, 2c,. Phone number or common ID number) is registered. The various information providers 4 include an information providing server 7 in which various information to be transmitted to the information providing server 7 (for example, information A, information B, information C,...) Is registered.

  Although not shown, the mobile phone 2 includes a control circuit including a CPU, a ROM and a RAM, a radio transmission / reception circuit, a voice input / output circuit, a modem circuit, a baseband circuit, an input circuit for a keyboard, and a display driver circuit for a display screen. And an interface for connecting to an external device, etc., and the destination information (for example, a common telephone number or a common ID number) for simultaneous transmission (for broadcast communication) is also stored in the ROM of the control circuit. ing. As shown in FIG. 1, the mobile phone 2 can be connected to a printer 8 for printing received information, a server 9 for storing received information, and the like.

  The portable switching center 3 simultaneously transmits information sent from various information providers 4 from the base stations 5a, 5b, 5c,... Based on the destination information for simultaneous transmission. The mobile phone operator allocates one or a plurality of specific frequency bands in advance for simultaneous transmission separately from the frequency band for general communication among the mobile phone use bands assigned to the mobile phone operator.

  FIG. 2 is a diagram showing one mode of a plurality of mobile phone use bands assigned to one mobile phone operator and a frequency band used for simultaneous transmission. In FIG. 2, there are five mobile phone usage bands allocated to one mobile phone operator, and four of those bands are used for general communication, and the remaining 1 is separate from the general communication frequency band. Are assigned as specific frequency bands for simultaneous transmission.

  When allocating a specific frequency band, various coded signals such as time division multiple access (TDMA) (time division multiple access) and W-CDMA (code division multiple access) (code division multiple access) are used. It can be applied to.

  FIG. 3 is a flowchart for explaining a series of operations until receiving the information providing service. When the customer applies for the information providing service to the portable switching center 3 (step S01), the customer's name, gender, address, etc. are registered in the customer database of the portable switching center 3 (step S02). In addition, transmission destination information (ID number or telephone number) for simultaneous transmission (for broadcast communication) is recorded on the mobile phone 2 possessed by the customer. When information is sent from the various information providers 4, the portable switching center 3 receives the information sent from the various information providers 4 (step S03) and selects a specific frequency band assigned for simultaneous transmission (step S04). Based on the transmission destination information for simultaneous transmission, the information is transmitted to a base station in the area where the mobile phone is located (step S05), and the information placed in the specific frequency band is transmitted from the base station to the corresponding mobile phone. (Step S06), it is received by the mobile phone (Step S07). The received information is stored in the memory in the mobile phone 2 (step S08). The information stored in the memory is displayed on the display unit of the mobile phone 2 and recognized by the customer (step S09).

  In FIG. 1, an example is shown in which information is simultaneously transmitted from the base stations 5a, 5b, and 5c to the respective mobile phones 2a, 2b, and 2c and received by the mobile phones 2a, 2b, and 2c. Show.

  As described above, according to the mobile phone system 1, various information can be transmitted within a limited time, and an information providing service by simultaneous transmission to N persons can be efficiently performed. The mobile switching center 3 represents the entire mobile switching center in the mobile phone operator. Therefore, even when the mobile phone 2a moves from one mobile phone switching center to another mobile phone switching center, the reception frequency is changed. There is no need to change.

  The information provision service is performed by simultaneous transmission to a cellular phone set with a telephone number or ID number for simultaneous transmission in a time zone with low radio wave traffic such as nighttime and early morning. As a result, the time zone in which the transmission equipment has not been used in the past is effectively used, the radio wave usage efficiency is increased, and the mobile switching center (communication carrier) 3 has a usage fee for providing information. Since it is profitable even if it is very cheap, the radio wave use cost is low, and the information providing service can also be low in terms of transmission cost. Further, when there are a plurality of simultaneous transmission users in the same wireless zone, the cost decreases in inverse proportion to the number of users.

  In addition, it is not a transmission using a specific device for a specific group as in the past, and it is not a transmission to a limited area such as low power, so information can be transmitted over a wide range, so that it can be used for general mobile phone users An information providing service becomes possible. In addition, for example, it is possible to communicate in real time with personnel in organizations such as government offices, local governments, and companies, and emergency communication in the event of a disaster such as an earthquake or fire is possible.

  Furthermore, for example, in the provision of information by newspapers, the morning newspaper deadline is around 11:00 pm on the previous day, and the news after that is not reflected in the articles, and is inferior to television in terms of real-time news, Readers do not read all articles, but all newspapers need to be printed, newspaper delivery to readers is time consuming and labor intensive, and newspaper costs are high There are various problems. These problems are solved by simultaneously distributing necessary information to a receiving terminal such as a mobile phone and displaying it on a display such as a printer or a liquid crystal by a printer.

  As described above, as a business field to which the present invention belongs, if news distribution is connected to a printer in each home, it can replace a newspaper. Similarly, the distribution of magazines and books can be provided at a lower cost than the usual printing, delivery, bookstore, and home routes. Also, catalogs, flyers, etc. can be distributed at a low price. Furthermore, if the contents of the information providing service are replaced with data, it is possible to remotely control various devices located in various regions. In addition, it is possible to change the software and data of computers and network devices installed in various regions in an instant.
