Description

  The present invention relates to a lottery system and its lottery server and lottery terminal, and in particular, a lottery system for autonomously performing a lottery in which a lottery terminal acquires a winning probability from a lottery server and wins itself with the winning probability, and the lottery server thereof And a lottery terminal.

  In Patent Document 1, as a lottery system using television broadcasting, a service providing side broadcasts lottery information including lottery winning conditions via a predetermined channel, and a service receiving side receives lottery information via a predetermined channel. A lottery service providing system is disclosed in which the received lottery information is collated with the lottery information stored in the lottery information and the lottery winning determination is made based on the collation result. Here, the lottery information stored on the service receiving side is attribute information such as the viewer's age group, gender, residential area, hobby, etc., and matches the attribute information broadcasted as lottery information from the service providing side. The viewer of the attribute information is the winner.

  In Patent Document 2, as a method for realizing lottery / application using broadcast content and the Internet, information including URL information used by a broadcaster for lottery / application is broadcast as video content. A technique is disclosed in which a broadcaster registers a lot of information based on the registered contents by connecting to the URL included in the information and registering his / her information.

  However, in the technique disclosed in Patent Document 1, attribute information such as a user's age group, sex, residential area, and hobbies must be registered in advance in the user's system as lottery information. In addition, lottery information broadcast from the service provider is set by a combination of age group, gender, residential area, hobbies, etc., and the winners can be selected in advance by the service provider's work, so fair lottery is difficult. It was. Furthermore, since it is difficult to accurately predict the number of winners matching the lottery information in advance, there is a problem that it is difficult to apply to a lottery with a limited number of winners.

In the technique disclosed in Patent Document 2, since it is necessary to accept pre-registration from applicants, the service provider must prepare a large-capacity server according to the scale of the lottery. In some cases, network pre-registration caused congestion. Furthermore, there has been a problem that applications from users who consider pre-registration complicated cannot be expected.

  In response to such a technical problem, the inventors of the present invention transmit lottery data including the winning probability to all the communication terminals to be selected, and each communication terminal wins within its own terminal based on the winning probability. Invented a technology that autonomously makes the determination and only the winning communication terminal notifies the lottery server of the winning fact, and applied for a patent (Patent Document 3).

JP 2002-140458 A JP 2007-323424 A Japanese Patent Application No. 2008-185996

  According to Patent Document 3, a communication terminal that has received a winning probability makes a winning determination in its own terminal, and only the winning communication terminal notifies the lottery server of the winning fact, so access from the lost communication terminal occurs. Absent. For this reason, the number of calls to the lottery server and the infrastructure and the reduction of traffic can be expected. Furthermore, since it is not necessary to notify the lottery server of the personal information of the user who has been elected, it also has the effect of protecting personal information.

  However, in Patent Document 3, since the winning probabilities notified to the lottery target communication terminals are unique and constant, the winning probabilities of all the lottery terminals are always the same. For this reason, it has not been possible to prompt the user to autonomously change the attribute by temporarily giving a high winning probability to a user having some attribute (for example, a good customer).

  The purpose of the present invention is to solve the above-mentioned problems of the prior art and to make the winning probability change autonomously according to the lottery target terminal and the user attribute information, thereby prompting the user to autonomously change the attribute information. The system and its lottery server and communication terminal are provided.

According to the present invention, the following effects are achieved.
(1) Since the winning probability of each lottery terminal can be varied according to the attribute, the winning probability of each lottery terminal can be arbitrarily controlled with the intention of the lottery side.
(2) Since the winning probability of each lottery terminal can be varied according to the attribute, the user of each lottery terminal can be urged to voluntarily change the attribute.
(3) The base station to which each lottery terminal is wirelessly connected for communication is the connection destination attribute, and the winning ratio to be assigned to the lottery terminal having the base station with many connected terminals as the connection destination attribute is If the winning ratio assigned to a lottery terminal having a base station with a small number of terminals as a connection destination attribute is set lower, the number of lottery terminals connected to each base station can be equalized.
(4) The lottery with the communication area to which the current position of each lottery terminal belongs as its position attribute and the winning ratio assigned to the lottery terminal with the communication area with a large number of terminals as the position attribute, with the communication area with a low number of terminals as the position attribute If the winning ratio assigned to the terminals is set lower, the number of terminals in each communication area can be equalized.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a broadcasting / communication integrated network to which the lottery system of the present invention is applied. Broadcasting equipment 5 is a broadcasting facility in which television video content and data communication content are multiplexed. A broadcast station 1 that transmits the broadcast wave, a portable communication terminal MN such as a television, a computer, and a mobile phone that receives the broadcast wave and reproduces the broadcast content, a radio base station 2 that accommodates these communication terminals MN, A lottery server 4 connected to the base station 2 via an IP network 3 such as the Internet and managed by a lottery service provider is a main component. The communication terminal MN is a lottery terminal that acquires a winning probability from the lottery server 4 by a broadcast wave and autonomously performs a lottery to win itself with the winning probability.

  In such a configuration, the lottery server 4 transfers to the broadcasting station 1 lottery data in which a lottery application guideline, a winning probability Rg, a winning ratio ri unique to each attribute condition i described later, and the like are described. The broadcast station 1 multiplexes the lottery data into a broadcast wave and transmits it from the broadcast facility 5. The communication terminal MN receives the broadcast wave and extracts from the lottery data the application guideline and the winning probability Rg, and the winning ratio ri associated with the attribute condition i satisfying its own attribute, and the winning probability Rg and the winning probability are extracted. Appropriate lottery that the terminal wins is autonomously executed with an attribute winning probability (Rg × ri) determined by the ratio ri. The selected communication terminal MN notifies the lottery server 4 of its own ID via the IP network as necessary.

  FIG. 2 is a block diagram showing the configuration of the lottery server 4 according to the first embodiment of the present invention. In the attribute information database 101, attribute information such as age, gender, and preference unique to each terminal user, which is pre-aggregated by a questionnaire survey from users of each communication terminal MN or recorded at the time of service contract of communication service, etc. Are registered in advance as user attributes. In the attribute information database 101, attribute information related to a communication service or a communication method with which the user of the communication terminal MN has a contract is registered in advance as a contract attribute. The attribute condition setting unit 102 sets an attribute condition i for classifying the lottery objects based on the attributes. In the present embodiment, as will be described in detail later, the attribute condition i is set as a user attribute, a contract attribute, or a logical expression thereof, and a winning ratio ri is set for each attribute condition i.

  The attribute condition user number estimation unit 103 refers to the database 101 to estimate the lottery target user number Mi for each attribute condition i. The winning ratio setting unit 104 for each attribute condition is based on the separately selected winning probability Rg and the number of users Mi satisfying each attribute condition i, or regardless of the winning probability Rg and the number of users Mi. The winning ratio ri is set for each. The lottery data generation unit 105 generates lottery data in which the winning probability Rg and the winning ratio ri are described. The lottery data transfer unit 106 transfers the lottery data to the broadcast station 1 and requests transmission by broadcast waves.

FIG. 3 is a block diagram showing the configuration of the communication terminal MN in the present embodiment. The storage unit 202 stores user attributes and / or contract attributes of the communication terminal MN or terminal user. The lottery data receiving unit 201 receives broadcast waves and extracts lottery data. Probability extracting unit 203 extracts the winning probability Rg and the attribute condition i described in the lottery data, further compares the user attribute or contract attribute for each attribute condition i and its own its own attributes satisfy The winning ratio ri associated with the attribute condition i to be extracted is extracted. The lottery unit 204 includes a random number generation unit that generates a random number rand of 0 <rand ≦ 1, and calculates the product Rg · ri of the winning probability Rg and the winning ratio ri as the winning probability for each attribute condition. Then, the random number rand and the attribute condition winning probability Rg · ri are compared, and if rand ≦ Rg · ri, the terminal is determined as the winning terminal. The winning result is reported to the lottery server 4 by the winning reporting unit 205.

  Next, the operation of this embodiment will be described in detail with reference to a flowchart. FIG. 4 is a flowchart mainly showing the operation of the lottery server 4, and FIG. 5 is a flowchart mainly showing the operation of the communication terminal MN.

In the lottery server 4, in step S <b> 1 in FIG. 4, the attribute condition setting unit 102 sets a lottery target attribute condition i. In the present embodiment, it is assumed that the user of each communication terminal MN is identified by two user attributes “A” and “B”, and four attribute conditions i1 expressed by logical expressions of these two user attributes A and B. To i4 are set as follows.

i1: An attribute condition that does not correspond to either attribute A or B, and is represented by the subscript [Ω−A∪B].
i2: An attribute condition corresponding to attribute A and not corresponding to attribute B, represented by the subscript [A−B].
i3: An attribute condition that falls under attribute B and does not fall under attribute A, and is represented by the subscript [B−A].
i4: An attribute condition corresponding to both attributes A and B, represented by the subscript [B∩A].

In step S2, based on the user IDs of the user attributes A and B registered in the database 101, the number of users Mi ( _MΩ−A∪B , M _A−B and M _B− that satisfy each attribute condition i). _A, M _A∩B) and total number M (= ΣMi) is estimated. In step S3, the winning ratio ri ( _rΩ−A∪B , _{rA −B} , _{rB −A} , _rA∩B ) set according to the number of users Mi for each attribute condition i is as follows. Calculated based on each equation (1).

Each equation (1) is derived as follows. In the present embodiment considering that the probability of winning more user groups of more attribute condition number of users Mi to lower Kunar so. In this case, since the total number of winners M · Rg is equal to the total number of winners for each attribute condition, the following equation (2) is established.

On the other hand, since the winning ratio ri for each attribute condition depends on the ratio of the number of users Mi that satisfy each attribute condition, the winning ratios for each attribute condition r _Ω−A∪B , r _A−B , r _B−A , r _A∩B must satisfy the following equation (3).

The above equation (3) can be expressed as the following equation (5) when the matrix A and the vectors r and M are defined as the following equations (4). Therefore, the following equation (6) by calculating the winning ratio r _Omega-A∪B each attribute _{condition, r A-B, r B} -A, can be calculated r _A∩B. That is, since the matrix A is a diagonal matrix having a positive diagonal component and is regular, the vector r can be calculated by obtaining its inverse matrix, and the above equation (1) is obtained.

In step S4, the winning percentage r _Omega-A∪B each attribute _{condition, r A-B, r B} -A, the lottery data r _A∩B is described is generated. In step S5, the lottery data is transferred to the broadcast station 1 and then broadcast at an appropriate timing.

  When the communication terminal MN receives the broadcast wave in which the lottery data is multiplexed in step S61 of FIG. 5, the communication terminal MN proceeds to step S62, and from the lottery data, the application guideline and the lottery result report destination address (in this embodiment, lottery Server 4 address), winning probability Rg and attribute condition Mi are extracted. In step S63, the winning ratio ri associated with the attribute condition Mi satisfying its own attribute is extracted. In step S64, the extracted application guidelines, winning probability Rg, and winning ratio ri for each attribute condition are displayed in a list on a terminal display (not shown). The terminal user can recognize the winning ratio ri of each attribute condition by referring to this list display, so knowing how to change his / her attributes will increase the winning ratio ri and increase the winning probability Can do. In step S65, the presence / absence of a lottery application operation by the terminal user is determined, and if an application operation is detected, the process proceeds to step S66.

  In step S66, a random number rand of 0 <rand ≦ 1 is generated in the random number generation unit of the lottery unit 204. In step S67, the random number rand is compared with the product Rg · ri of the winning probability Rg and the winning ratio ri, and if rand ≦ Rg · ri, the terminal is determined to be the winning terminal that won the current lottery and step S68. The winning message is displayed on the terminal display. In step S69, a winning notification message is generated and transmitted to the lottery server 4 in step S70. On the other hand, if it is determined that the selection is lost in step S67, the process proceeds to step S71, and a selection message is displayed on the terminal display.

  According to the present embodiment, since the winning probability of each communication terminal can be varied according to the attribute, the winning probability of each communication terminal can be arbitrarily controlled with the intention of the lottery side.

  Next, a second embodiment of the present invention will be described. In the first embodiment, the attribute condition is a user attribute or a contract attribute. In the present embodiment, the attribute condition is a communication area of the communication terminal, and each communication terminal MN has a communication area at the current position. It is characterized in that the winning ratio ri is set based on this. Here, as shown in FIG. 6, a higher winning ratio ri is set for the communication terminal MN located in the communication area Ea with a smaller number of terminals than for the communication terminal MN located in the communication area Eb with a larger number of terminals. Thus, it is considered to equalize the number of terminals in each communication area.

  FIG. 7 is a block diagram showing the configuration of the lottery server according to the present embodiment, and the same reference numerals as those described above represent the same or equivalent parts.

  The database 101 stores the current position P0 of each communication terminal MN as a position attribute. The attribute information setting unit 102 sets an attribute condition for classifying the lottery objects according to their position attributes and assigning different winning ratios ri. In the present embodiment, two communication areas Ea and Eb are set as attribute conditions.

  The attribute condition user count estimation unit 103 refers to the database 101 to estimate the lottery target user count Mi for each attribute condition. In the present embodiment, the number of users Ma in the communication area Ea and the number of users Mb in the communication area Eb are estimated. The winning ratio setting unit 104 for each attribute condition is based on a separately selected winning probability Rg and the number of users Ma and Mb satisfying each attribute condition Ea and Eb, or regardless of the winning probability Rg and the number of users Ma and Mb. The winning ratios ra and rb are set for each of the attribute conditions Ea and Eb. The lottery data generation unit 105 generates lottery data in which the winning probability Rg and the winning ratios ra and rb of the communication areas Ea and Eb are described. The lottery data transfer unit 106 transfers the lottery data to the broadcast station 1 and requests transmission by broadcast waves.

  FIG. 8 is a block diagram showing the configuration of the main part of the communication terminal MN in the present embodiment. The current position positioning unit 206 measures the current position P0 using, for example, GPS. The lottery data receiving unit 201 receives broadcast waves and extracts lottery data. The probability extraction unit 203 extracts the winning probability Rg and the attribute conditions Ea and Eb described in the lottery data, and compares the attribute conditions Ea and Eb with its current position P0. If the current position P0 belongs to the communication area Ea, the winning ratio ra is extracted, and if the current position P0 belongs to the communication area Eb, the winning ratio rb is extracted. Here, the description will be continued assuming that the communication terminal MN is located in the communication area Ea and the winning ratio ra is extracted. The lottery unit 204 compares the random number rand and the product Rg · ra of each probability. If rand ≦ Rg · ra, the lottery unit 204 determines that the terminal is the winning terminal.

  Next, the operation of this embodiment will be described in detail with reference to a flowchart. FIG. 9 is a flowchart mainly showing the operation of the lottery server 4, and FIG. 10 is a flowchart mainly showing the operation of the communication terminal MN.

  In the lottery server 4, a lottery target attribute condition is set in step S21 of FIG. In the present embodiment, two communication areas Ea and Eb are set as attribute conditions in order to classify the users to be selected by the current position P0 and assign different winning ratios ri. In step S22, the numbers of users Ma and Mb of the communication terminals MN belonging to the communication areas Ea and Eb are estimated. Here, provisional estimation is performed based on past performance data and the like. In step S23, winning ratios ra and rb for the communication areas Ea and Eb are calculated. In the present embodiment, the communication area Ea, Eb is configured so that the number of users in each communication area is equalized by lowering the winning ratio of the communication area with a large number of users to be lower than the winning ratio of the communication area with a small number of users. The winning ratios ra and rb are calculated based on the following equations (7) and (8). In step S24, lottery data in which the winning probability Rg and the winning ratios ra and rb are described is generated, transferred to the broadcasting station 1, and broadcast on the broadcast wave.

  Proceeding to FIG. 10, when the communication terminal MN receives the broadcast wave in which the lottery data is multiplexed in step S61, in step S62, the lottery application guideline, the winning report destination address, the winning probability Rg and the lottery data are selected from the lottery data. Attribute conditions Ea and Eb are extracted. In step S62a, the positioning unit 206 measures the current position P0. In step S63, the winning ratio associated with the attribute condition satisfying its own position attribute (current position P0) is extracted. Here, since the current position P0 of the communication terminal MN belongs to the communication area Ea, the winning ratio ra is extracted.

  In step S64, the extracted application guidelines, winning probability Rg, and winning ratio ri for each attribute condition are displayed in a list on a terminal display (not shown). Thereby, since the terminal user can recognize a communication area with a high winning ratio, if the winning probability is to be increased, it is only necessary to move to a communication area with a high winning ratio ri.

  In step S65, the presence / absence of a lottery application operation by the terminal user is determined, and if an application operation is detected, the process proceeds to step S66. In step S66, a random number rand of 0 <rand ≦ 1 is generated in the random number generation unit of the lottery unit 204. In step S67, the random number rand is compared with the product Rg · ra of the winning probability Rg and the winning ratio ra, and if rand ≦ Rg · ra, the terminal is determined to be the winning terminal that won the current lottery and step S68. The winning message is displayed on the terminal display. In step S69, a winning notification message is generated and transmitted to the lottery server 4 in step S70.

  Returning to FIG. 9, the lottery server 4 receives the winning notification message transmitted from each of the selected communication terminals MN in step S25. In step S26, the winning terminal number Ma 'satisfying the attribute condition of the communication area Ea is' Ma · ra · Rg ', and the winning terminal number Mb' satisfying the attribute condition of the communication area Eb is Mb · rb · Rg. Based on this, the numbers of users Ma and Mb of the communication areas Ea and Eb are estimated based on the following equations (9) and (10).

  In step S27, it is determined whether or not the numbers of users Ma and Mb of the communication areas Ea and Eb are approximately the same. If it is not the same level, the process returns to step S23, the number of users Ma and Mb estimated in step S26 is applied to the above formulas (7) and (8), and the winning ratios ra and rb are updated. Each process is repeated.

  Next, a third embodiment of the present invention will be described. The present embodiment is characterized in that the attribute condition is a base station to which each communication terminal is connected, and the winning ratio ri is set for each communication terminal MN based on the connection destination. Here, as shown in an example in FIG. 11, the communication terminal MN accommodated in the base station Qa with a small number of connections has a higher winning ratio ri than the communication terminal MN accommodated in the base station Qb with a large number of connections. It is considered to equalize the number of connections to each base station by setting.

  FIG. 12 is a block diagram showing the configuration of the lottery server 4 according to the third embodiment of the present invention. The same reference numerals as those described above represent the same or equivalent parts.

  In the database 101, the radio base station to which each communication terminal MN is connected is stored as a connection destination attribute. The attribute information setting unit 102 sets attribute conditions for assigning different winning ratios ri by classifying the lottery objects according to the connection destination information. In this embodiment, two radio base stations Qa and Qb are set as attribute conditions. The attribute condition user count estimation unit 103 refers to the database 101 to estimate the lottery target user count Mi for each attribute condition. In the present embodiment, the number of users Ma of the radio base station Qa and the number of users Mb of the radio base station Qb are estimated. The winning ratio setting unit 104 for each attribute condition is based on the separately selected winning probability Rg and the number of users Ma and Mb that satisfy each attribute condition, or regardless of the winning probability Rg and the number of users Ma and Mb. The winning ratios ra and rb are set for each. The lottery data generation unit 105 generates lottery data in which the winning probability Rg and the winning ratios ra and rb of the base stations Qa and Qb are described. The lottery data transfer unit 106 transfers the lottery data to the broadcast station 1 and requests transmission by broadcast waves.

  FIG. 13 is a block diagram showing a configuration of a main part of the communication terminal MN in the present embodiment. The connection destination identification unit 207 identifies a connection destination radio base station. The lottery data receiving unit 201 receives broadcast waves and extracts lottery data. The probability extraction unit 203 extracts a winning probability Rg and attribute conditions described in the lottery data, and further compares each attribute condition with its own attribute. Then, if the connection destination is the radio base station Qa, the winning ratio ra is extracted, and if the own connection destination is the radio base station Qb, the winning ratio rb is extracted. Here, the description will be continued on the assumption that the own connection destination is the radio base station Qa and the winning ratio ra is extracted. The lottery unit 204 compares the random number rand and the product Rg · ra of each probability, and determines that the terminal is the winning terminal if rand ≦ Rg · ra.

  Next, the operation of this embodiment will be described in detail with reference to a flowchart. FIG. 14 is a flowchart mainly showing the operation of the lottery server 4, and FIG. 15 is a flowchart mainly showing the operation of the communication terminal MN.

  In the lottery server 4, a lottery target attribute condition is set in step S31 of FIG. In the present embodiment, two radio base stations Qa and Qb are set as attribute conditions in order to classify the users to be selected at the connection-destination radio base station and assign different winning ratios ri. In step S32, the numbers of users Ma and Mb of the communication terminals MN connected to the radio base stations Qa and Qb are estimated. Here, provisional estimation is performed based on past performance data and the like. In step S33, winning ratios ra and rb of users connected to the radio base stations Qa and Qb are calculated. In this embodiment, the winning ratio of radio base stations with a large number of connections is made lower than the winning ratio of radio base stations with a small number of connections, so that the number of connections to each radio base station Qa, Qb is made uniform. The winning ratios ra and rb of the radio base stations Qa and Qb are calculated in the same manner as described above. In step S34, lottery data in which the winning probability Rg and the winning ratios ra and rb of each attribute condition are described is generated, transferred to the broadcast station 1, and broadcast on the broadcast wave.

  Proceeding to FIG. 15, when the communication terminal MN receives the broadcast wave in which the lottery data is multiplexed in step S61, in step S62, the lottery application guideline, the winning report destination address, the winning probability Rg and the lottery data are selected from the lottery data. Attribute conditions Qa and Qb are extracted. In step S62b, the connection destination identifying unit 207 identifies the connection destination radio base station. In step S63, the winning ratio associated with the attribute condition that satisfies its own attribute (connection destination) is extracted. Here, since the connection destination of the communication terminal MN is the radio base station Qa, the winning ratio ra is extracted.

In step S64, the extracted application guidelines, winning probability Rg and winning ratio ri for each attribute condition are displayed in a list on the terminal display. Thereby, since the terminal user can recognize a base station with a high winning ratio, if the winning probability is to be increased, the terminal user has only to move within the coverage of a base station with a high winning ratio ri.
In step S65, the presence / absence of a lottery application operation by the terminal user is determined, and if an application operation is detected, the process proceeds to step S66. In step S66, a random number rand of 0 <rand ≦ 1 is generated in the random number generation unit of the lottery unit 204. In step S67, the random number rand is compared with the product Rg · ra of the winning probability Rg and the winning ratio ra. The winning message is displayed on the terminal display. In step S69, a winning notification message is generated and transmitted to the lottery server 4 in step S70.

  Returning to FIG. 14, the lottery server 4 receives the winning notification message transmitted from each winning communication terminal MN in step S35. In step S36, the winning terminal number Ma ′ satisfying the attribute condition that the radio base station Qa is the connection destination is Ma · ra · Rg, and the winning terminal satisfying the attribute condition that the radio base station Qb is the connection destination Based on the fact that the number Mb ′ is Mb · rb · Rg, the numbers of users Ma and Mb to which the radio base stations Qa and Qb are connected are estimated in the same manner as described above.

  In step S37, it is determined whether or not the numbers of users Ma and Mb having the wireless base stations Qa and Qb as connection destinations are approximately the same. If not, the process returns to step S33, and the winning ratios ra and rb are updated by applying the numbers of users Ma and Mb estimated in step S36 to the above equations (7) and (8). Each process is repeated.

  In each of the above embodiments, the winning ratio ri for each attribute has been described as being calculated based on the number of users Mi and the winning probability Rg. However, the present invention is not limited to this, and the winning ratio ri May be arbitrarily set on the lottery side regardless of the number of users Mi or the winning probability Rg. In this way, the winning probability Rg · ri for each attribute can be arbitrarily set on the lottery side.

  In each of the above embodiments, the winning probability Rg and the winning ratio ri for each attribute are given as lottery data from the lottery server 4 to each communication terminal MN, and each communication terminal MN is based on the winning probability Rg and the winning ratio ri. However, the present invention is not limited to this, and the lottery server 4 reflects the winning ratio ri based on the winning probability Rg and the winning ratio ri for each attribute. The attribute-specific winning probability Rg · ri may be calculated in advance for each attribute, and the lottery data in which the attribute-specific winning probability Rg · ri is associated with each attribute condition may be transmitted to each communication terminal MN.

  Furthermore, the attributes of each lottery terminal are not limited to the above. For example, in viewing a TV program or the like, viewing such as the viewing time or the number of times of viewing of a program content or a broadcast content such as a CM viewed by each user on the lottery terminal. If the lottery terminal with more viewing time and number of times of viewing is counted as attribute information (viewing attributes) and the winning ratio is higher, the viewing time and number of times of view are arbitrarily controlled by the user's will. become able to.
