  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention. In the drawings, the same or similar parts are denoted by the same reference numerals, and redundant description may be omitted.

  A first embodiment of the present invention will be described with reference to FIG. FIG. 1 schematically shows an example of the configuration of a download system according to the first embodiment. In FIG. 1, a download system 10 includes mobile terminals 100 and 101, an access point (corresponding to a download station) 200, and a program distribution server 500. The wireless LAN area 300 is a service area for wireless LAN communication constructed by the wireless LAN function of the access point 200. Access point 200 and program distribution server 500 may be communicably connected via backbone network 400.

The backbone network 400 may be the Internet, a dedicated line, a wireless packet, or a combination thereof. Further, the transmission path connecting the access point 200 and the backbone network 400 may be wired communication or wireless communication. Wireless communication methods include 3G, Wi-Fi (registered trademark), AXGP, TD-LTE, FD-LTE, satellite communications, Bluetooth (registered trademark), ZigBee (registered trademark), optical wireless, LTE-Advanced, etc. However, the communication method is not limited.

The access point 200 has a function as a wireless LAN access point, and performs data communication with the mobile terminals 100 and 101 located in the wireless LAN area 300. The access point 200 may have the base station function of the mobile terminals 100 and 101 instead of the wireless LAN access point function, or may have both the wireless LAN access point function and the base station function.

The access point 200 transmits a beacon signal at a constant period. The portable terminals 100 and 101 are located in the wireless LAN area 300 by moving to a position where the beacon signal can be received. For example, the mobile terminal 100 at point A is out of the wireless LAN area 300 because it is far from the access point 200 and cannot receive a beacon signal. However, when the mobile terminal 100 moves from the point A to the point B, the distance from the access point 200 is reduced and the beacon signal can be received, and the mobile terminal 100 is located within the wireless LAN area 300. Similarly, when the mobile terminal 101 moves from the C point to the D point, the distance from the access point 200 is reduced and the beacon signal can be received, and the mobile terminal 101 is located within the wireless LAN area 300.

When the mobile terminals 100 and 101 receive a beacon signal transmitted from the access point 200, authentication processing is performed with the access point 200. When the authentication processing is normally performed between the mobile terminals 100 and 101 and the access point 200, the mobile terminals 100 and 101 can receive the programs 501 and 502 distributed by the program distribution server 500.

Here, the programs 501 and 502 include, for example, various application programs belonging to categories such as news, business, entertainment, hobbies, games, music, sports, utilities, and events related to the area where the wireless LAN area 300 is constructed. Information and store information. Facility information in the vicinity of the wireless LAN area 300, disaster occurrence information, evacuation site information, charging service information, disaster countermeasure application programs, and the like may be included.

Next, a program distribution procedure according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 8 schematically shows an example of a program distribution procedure according to the first embodiment of the present invention.

In FIG. 8, the access point 200 transmits a beacon signal at a constant period (S801). When the mobile terminal 100 moves from point A to point B in FIG. 1 and receives a beacon signal, the mobile terminal 100 transmits an authentication request signal to the access point 200 (S802). When the access point 200 receives the authentication request signal, the access point 200 performs an authentication check as to whether or not the mobile terminal 100 is a valid contract terminal. If the access point 200 determines that the mobile terminal 100 is a valid contract terminal 100, the access point 200 transmits an authentication response signal to the mobile terminal 100. (S803). In the case of an authentication-free service mode, the access point 200 may omit the authentication check, or send a pseudo authentication response signal to the mobile terminal 100 that assumes that the authentication is normally performed in a pseudo manner. Also good.

The access point 200 transmits an authentication response signal to the mobile terminal 100 and transmits a program distribution request to the program distribution server 500 when the mobile terminal 100 is detected in the wireless LAN area 300 ( S804). The program distribution request may be transmitted from the portable terminal 100 by a user operation of the portable terminal 100. When receiving a program distribution request from the access point 200, the program distribution server 500 transmits a program list created in advance to the access point 200 (S805). This program list includes programs 501, 502 and the like. The access point 200 relays the program list transmitted from the program distribution server 500 and transmits it to the mobile terminal 100 (S806). The program distribution server 500 and the access point 200 may transmit the program list transmission format in a format displayed on the screen of the mobile terminal 100 by a browser function provided in the mobile terminal 100.

The user of the portable terminal 100 browses the program list displayed on the screen of the portable terminal 100, selects the desired program 501, and performs a download request operation for the program 501. The portable terminal 100 transmits a download request signal for the program 501 to the access point 200 based on the user's operation (S807). The access point 200 relays the download request signal of the program 501 and transmits it to the program distribution server 500 (S808).

When receiving the download request signal for the program 501 from the access point 200, the program distribution server 500 downloads the requested program 501 (S809). The access point 200 relays the download of the program 501 and the mobile terminal 100 receives the desired program 501 (S810). The portable terminal 100 receives the program 502 by the same procedure as these. The portable terminal 100 activates the received programs 501 and 502, thereby enabling the functions provided in the programs 501 and 502 to be executed.

  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 2 shows an example of the configuration of a download system according to the second embodiment. The second embodiment of the present invention differs from the first embodiment in that program distribution is restricted based on the communication status of the access point 200.

In FIG. 2, the program distribution server 500 restricts distribution of the program 502 based on the communication status of the access point 200. Here, the communication status of the access point 200 includes the operation status of the access point 200, the setting status of the access point 200, the communication status between the access point 200 and the mobile terminal 100, and between the access point 200 and the backbone network 400. The environment information that can be acquired by the access point 200, such as the communication state of the wireless LAN area 300 and the number of mobile terminals in the wireless LAN area 300, is not limited thereto.

In FIG. 2, the mobile terminal 100 moves from the A point to the B point, and the mobile terminal 101 moves from the C point to the D point, so that they are in the wireless LAN area 300. When a large number of mobile terminals 102, 103,... (Not shown) are already in the wireless LAN area 300, the communication traffic in the wireless LAN area 300 depends on the location of the mobile terminals 100 and 101. Increases and congestion occurs. For example, the communication speed between each portable terminal and the access point 200 such as the portable terminals 100, 101, 102,. In such a state, when the mobile terminals 100 and 101 make download requests for the programs 501 and 502 and execute the programs 501 and 502 to start communication with the backbone network 400, communication traffic in the wireless LAN area 300 is generated. It will increase further and congestion will increase. In such a case, the access point 200 may limit the number or type of programs that can be downloaded to the mobile terminals 100 and 101.

For example, when the number of mobile terminals 102, 103,... Located in the wireless LAN area 300 reaches a preset number, the access point 200 sends a program to the program distribution server 500. Notify delivery restriction request. When receiving the program distribution restriction request from the access point 200, the program distribution server 500 restricts the distribution of the program 502, for example. As described above, by restricting the distribution of the program 502 to the mobile terminals 100 and 101, it is possible to suppress the expansion of congestion in the wireless LAN area 300.

Next, with reference to FIG. 6, a procedure for determining a program distribution restriction according to the second embodiment of the present invention will be described. FIG. 6 schematically shows an example of a determination procedure for distribution restriction of a program according to the second embodiment of the present invention. In FIG. 6, when the access point 200 detects the location of the mobile terminal 100 (S501), the access point 200 measures the communication state between the access point 200 and the backbone network 400 (S502). For example, the communication state may be measured by measuring the communication speed, response time, code error rate, etc. between the access point 200 and the backbone network 400.

If the measurement result of the communication state between the access point 200 and the backbone network 400 is within a predetermined threshold range, the access point 200 indicates that the communication state between the access point 200 and the backbone network 400 is Judge as normal. Then, the communication state with each portable terminal such as the portable terminals 100, 101,... Is measured (S503). For example, the communication state may be measured by measuring the communication speed between the access point 200 and each portable terminal, the response time, the code error rate, the SNR of the reference signal, and the like. Alternatively, the number of mobile terminals located in the wireless LAN area 300 may be measured.

When the communication state between the access point 200 and each portable terminal such as the portable terminals 100, 101,... Is within a predetermined threshold range, the access point 200 and each portable terminal It is determined that the communication state with the terminal is normal. In this case, it may be determined that the program distribution is not restricted (S504).

Here, if the measurement result of the communication state between the access point 200 and the backbone network 400 exceeds the predetermined threshold range in S502, the access point 200 has failed. It may be determined that the distribution of the program is restricted (S505). Here, the determination as to whether or not to restrict the distribution of the program may be made based on the measurement result of the communication state and the failure state based on the level of congestion or abnormality. In S503, if the measurement result of the communication state between the access point 200 and each portable terminal exceeds the predetermined threshold range, the program is regarded as having failed. It may be determined that the distribution is restricted (S505). Similarly, in this case, it may be determined that the distribution of the program is restricted by classifying the failure state by congestion or abnormality level.

Next, with reference to FIG. 7, a restriction pattern for restricting distribution of a program according to the second embodiment of the present invention will be described. FIG. 7 schematically shows an example of a distribution restriction pattern of a program according to the second embodiment of the present invention. In FIG. 7, when the access point 200 determines not to restrict the distribution of the program, the access point 200 does not restrict the distribution of the program 501, 502,. If the access point 200 determines that the program distribution is restricted, the program category, program size, number of program downloads, program producer, mobile phone, etc. for the programs 501, 502,. The program distribution may be limited by combining one or a plurality of elements such as the terminal type, the user attribute, and the program distribution time zone. The program distribution restriction may be determined in advance as patterns 1, 2, 3,...

The access point 200 is one of the value of the measurement result of the communication state between the access point 200 and the backbone network 400 and the value of the measurement result of the communication state between the access point 200 and each portable terminal described above. Alternatively, the distribution restriction pattern of the program may be determined based on both measurement result values.

Next, a program distribution procedure according to the second embodiment of the present invention will be described with reference to FIGS. FIG. 9 schematically shows an example of a program distribution procedure according to the second embodiment of the present invention. In FIG. 9, the procedure from S901 to S903 is the same as the procedure from S801 to S803 in the first embodiment described with reference to FIG. When the access point 200 determines to restrict distribution of the program 502, for example, in the program distribution restriction determination procedure and the program distribution restriction pattern described with reference to FIGS. A program distribution restriction request signal is transmitted (S904). The access point 200 may specify, for example, the distribution restriction patterns 1 and 2 shown in FIG. 7 in the program distribution restriction request signal.

When the program distribution server 500 receives the program distribution restriction request signal from the access point 200, the program distribution server 500 creates a program list after excluding programs corresponding to the designated distribution restriction pattern from the program list created in advance. 200 is transmitted (S905). In this example, the program list does not include the program 502. The access point 200 relays the program list received from the program distribution server 500 and transmits it to the mobile terminal 100 (S906). The program distribution server 500 and the access point 200 may transmit the program list transmission format in a format displayed on the screen of the mobile terminal 100 by a browser function provided in the mobile terminal 100.

When receiving the program list from the access point 200, the portable terminal 100 transmits a download request signal for the desired program 501 by the user's operation (S907). Thereafter, the portable terminal 100 receives the program 501 by the procedure of S908 to S910. A series of steps S907 to S910 is the same as steps S807 to S810 in the first embodiment described with reference to FIG.

  In the present embodiment, the access point 200 is specified in such a manner that the distribution restriction pattern is included in the program distribution restriction request signal. Instead, the program category, the program size, and the like are set as the distribution restriction target. You may specify concretely. In this case, the program distribution server 500 may create the program list based on the program category, the program size, and the like that are specifically designated. In creating the program list, priority may be given to the order displayed on the screen of the mobile terminal 100.

Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 3 shows an example of the configuration of a download system according to the third embodiment. The third embodiment of the present invention is different from the first embodiment and the second embodiment in that the access point 200 holds a specific program in advance.

The access point 200 may hold one or more specific programs in advance. In FIG. 3, the mobile terminal 100 moves from the A point to the B point, and the mobile terminal 101 moves from the C point to the D point, so that they are in the wireless LAN area 300. When the access point 200 detects the location of the mobile terminals 100 and 101, the access point 200 distributes the specific program 201 held in advance to the mobile terminals 100 and 101. Here, the specific program 201 may be a program designated by the provider installing the access point 200 or the provider distributing the program from the above-described programs 501, 502,. For example, it may be an area-limited program that is strongly related to the wireless LAN area 300. Moreover, it is good also as a program for disaster countermeasures. The access point 200 may download a specific program from the program distribution server 500 and hold it inside itself, or may fetch it from a storage medium such as a USB memory in which the specific program is stored in advance.

  Next, a program distribution procedure according to the third embodiment of the present invention will be described with reference to FIGS. FIG. 10 schematically shows an example of a program distribution procedure according to the third embodiment of the present invention. In FIG. 10, the procedure from S1001 to S1003 is the same as the procedure from S801 to S803 in the first embodiment described with reference to FIG.

  The access point 200 transmits an authentication response signal to the mobile terminal 100 (S1003), and transmits a specific program list held in advance (S1004). This specific program list includes specific programs 201,. Here, the access point 200 transmits the specific program list in such a manner that the specific program 201,... Can be identified, for example, by adding an icon or a description to the specific program limited to the area of the wireless LAN area 300. To do. The access point 200 may transmit the transmission format of the specific program list in a format displayed on the screen of the mobile terminal 100 by a browser function provided in the mobile terminal 100.

The user of the mobile terminal 100 browses the specific program list displayed on the screen of the mobile terminal 100, selects the desired specific program 201, and performs a download request operation for the specific program 201. The portable terminal 100 transmits a download request signal for the specific program 201 to the access point 200 based on a user operation (S1005). When receiving the download request signal for the specific program 201 from the mobile terminal 100, the access point 200 downloads the requested specific program 201 to the mobile terminal 100 (S1006). The portable terminal 100 activates the received specific program 201 to enable the functions provided in the specific program 201 to be executed.

Here, the access point 200 may distribute the specific program based on the communication status of the access point 200. For example, in the access point 200, after the mobile terminals 100, 101, 102, and 103 are located in the wireless LAN area 300, the communication state between the access point 200 and the backbone network 400 is a failure state such as congestion or abnormality. When it is detected, the distribution of other programs may be restricted and the specific program may be distributed with priority over other programs. Further, some of the specific programs may be distributed based on the communication status of the access point 200. For example, the distribution restriction of the program described with reference to FIGS. 6 and 7 may be applied to the distribution restriction of the specific program in the same manner as the distribution restriction of other programs. By controlling the distribution of the specific program in this way, a shopping coupon ticket limited to the area of the wireless LAN area 300 can be distributed according to the number of mobile terminals 100 or the like in the wireless LAN area 300, or vice versa. The distribution can be restricted.

Next, an example of the fourth embodiment of the present invention will be described with reference to FIG. FIG. 4 shows an example of the configuration of a download system according to the fourth embodiment. The fourth embodiment of the present invention is an example in which an ad hoc program that is one of the disaster countermeasure programs is distributed as the specific program in the third embodiment. The ad hoc program 202 is a program for causing the mobile terminal 100 to function as a tethering function or ad hoc communication.

  In FIG. 4, the access point 200 holds an ad hoc program 202, which is one of the disaster countermeasure programs, in advance. When each of the mobile terminals 100, 101, 102, 103 approaches the access point 200 and is in the wireless LAN area 300, the access point 200 is identified as a disaster countermeasure program such as an ad hoc program 202 or a safety confirmation program. Send the program list. Here, the access point 200 transmits the specific program list by making it possible to identify that the ad hoc program 202 or the safety confirmation program is a disaster countermeasure program with an icon or a description.

The mobile terminal 100, 101, 102, 103 transmits a download request signal for the ad hoc program 202 to the access point 200 by the operation of the user using the mobile terminal 100, 101, 102, 103. The access point 200 downloads the ad hoc program 202 to the mobile terminals 100, 101, 102, 103. When the received ad hoc program 202 is installed and activated, the mobile terminals 100, 101, 102, and 103 can execute ad hoc communication.

The mobile terminals 101, 102, and 103 move away from the access point 200 and move out of the wireless LAN area 300. In such a case, since the mobile terminals 101, 102, and 103 cannot communicate with the access point 200, they cannot communicate with the backbone network 400.

Here, when the ad hoc program 202 downloaded and installed from the access point 200 is activated, the mobile terminals 100, 101, 102, and 103 are switched from the infrastructure mode to the ad hoc mode. When the portable terminals 100, 101, 102, and 103 are switched to the ad hoc mode, the portable terminals can communicate with each other.

The access point 200 relays data transmitted from each of the mobile terminals 100, 101, 102, 103 and transmits it to the backbone network 400. In addition, the access point 200 relays data transmitted from the backbone network 400 and transmits the data to each of the mobile terminals 100, 101, 102, and 103. As a result, the mobile terminals 101, 102, and 103 that have moved out of the wireless LAN area can communicate with the backbone network 400 via the access point 200.

FIG. 4 shows an example of tandem connection between an access point 200 and a mobile terminal 100-101-102-103 as a connection form between mobile terminals. However, by using an ad hoc communication function, The terminals 100, 101, 102, and 103 can also realize a mesh-like connection form.

Next, an example of a download system according to the fifth embodiment of the present invention will be described with reference to FIG. FIG. 5 shows an example of ad hoc communication in the fifth embodiment. In FIG. 5, when a failure occurs between the access point 200 and the backbone network 400, the access point 200 may be switched to the stand-alone mode. When the access point 200 switches to the stand-alone mode, the access point 200 searches for another access point 205 capable of communication, for example, by transmitting a probe signal, and establishes communication with the other access point 205. . Accordingly, the mobile terminals 100, 101, 102, and 103 can communicate with the backbone network 400 via the access point 200 and other access points 205. Here, the access point 200 may be switched to the stand-alone mode depending on the level of the failure state, such as when congestion between the access point 200 and the backbone network 400 is not solved for a long time or when communication is interrupted. .

4 and 5, the access point 200 has described an example in which the ad hoc program 202 is distributed when it is detected that the mobile terminals 100, 101, 102, and 103 are located in the wireless LAN area 300. The point 200 indicates that the communication state between the access point 200 and the backbone network 400 is a failure state such as congestion or abnormality after the mobile terminals 100, 101, 102, 103 are in the wireless LAN area 300. When detected, the ad hoc program 202 may be distributed.

Further, the access point 200 may distribute another disaster countermeasure program together with the ad hoc program 202. For example, a program for guiding battery charging of the mobile terminal, a program for confirming safety, and a program for guiding to an evacuation site in an emergency may be distributed. Here, the access point 200 distributes the ad hoc program by making it possible to identify that the ad hoc program 202 is an ad hoc communication program that enables mobile terminals to communicate with each other through a tandem connection or a mesh connection with an icon or a description. To do. May be. Similarly, a program for inducing battery charging of a portable terminal, a safety confirmation program, and the like may be distributed in an identifiable manner so that the purpose and function of the program can be understood.

Further, when distributing such a disaster countermeasure specific program, the access point 200 may omit the authentication process with the mobile terminal, or send a pseudo authentication response to make the authentication free. Also good. Thereby, even if it is portable terminals other than a contract terminal, the disaster countermeasure program can be downloaded from the access point 200. As a result, communication in the ad hoc mode is possible even between mobile terminals with different contractors.

  Such an access point 200 that distributes the disaster countermeasure specific program 201 is particularly useful in an area where radio waves from the base station of the mobile terminal are difficult to reach, such as indoors, underground, mountaintops, sea, airplanes, etc. can do.
