Reference numeral 2 denotes a plurality of service servers connected to the center system 1 and the network 3, and provides various services to users. Reference numeral 4 denotes the Internet to which the center system 1 is connected. Reference numeral 5 denotes a mobile communication network connected to the Internet 4 and establishes communication with a mobile terminal 6.
[0018]
Subsequently, the operation will be briefly described. First, when the user instructs the start of a service from the terminal 6, mobile terminal information (position information, speed information) is transmitted from the terminal 6 to the center system 1 in accordance with the movement of the mobile (car) equipped with the terminal 6. . The center system 1 holds mobile content and transmits mobile information to a service server 2 that provides a service. There may be a plurality of service servers 2. The service server 2 searches for the content based on the mobile unit information and returns the content to the center system 1. Alternatively, the service server 2 pushes the content to the center system 1 based on a unique schedule. The center system 1 arranges the received distribution contents from the plurality of service servers 2 in a user sequential manner, filters the contents according to the designation of the user (which service is received), and push-distributes the contents to the terminal 6.
[0019]
Next, a detailed configuration of the apparatus shown in FIG. 1 will be described with reference to FIG. The terminal 6 includes an information receiving unit 61 that receives information pushed from the center system 1 and an information transmitting unit 62 that transmits sensor information such as GPS (not shown) to the center system 1.
[0020]
The center system 1 receives a request from the terminal 6, performs necessary processing, or transmits a processing request to the outside, and generates and transmits a result to be returned to the terminal 6. The service server GW layer 16 receives a push request and transmits the push request to the terminal GW layer 11.
The terminal GW layer 11 receives a request from the terminal 6 and an uplink of sensor information, understands the request, starts a necessary process, and an SS (service server) which has access to a page held by the service server 2. A) a page access unit 13, a distribution control unit 14 that receives a push request from the service server GW layer 16, performs conversion according to the terminal type, and push-distributes to the terminal 6, and transmits information of each terminal 6. It has a terminal management database 15 for managing.
The service server GW layer 16 includes a distribution receiving unit 17 that receives a push distribution request from the service server 2 and transmits the push distribution request to the terminal GW layer 11, and an SS (service server) management database that manages the service server 2.
[0021]
The service server 2 returns a screen in response to a request from the terminal GW layer 11, receives the uplink information received from the terminal GW layer 11, performs a necessary process, and acquires a distribution content. A distribution management unit 22 that transmits a distribution request to the service server GW layer 16, a registration reception unit 23 that receives a registration request from the information provider terminal 7, and a distribution information database 24 that stores distribution contents.
[0022]
Next, the operation of login / logout will be described with reference to FIG. First, the terminal 6 transmits a login request to the request receiving unit 12 in order to be authenticated for use of the service (step S1). This login request includes the version information of the terminal 6 in addition to the user's own ID and password. In response to this, the request receiving unit 12 refers to the terminal management database 15 based on the user ID and the password information, determines whether or not user authentication is possible, and transmits a login notification to the terminal 6 when authentication is successful. (Step S2). After the authentication, each service page provided by the service server 2 can be accessed to receive the service (step S3). This eliminates the need for individual services to individually perform user authentication, and facilitates service server construction. In addition, since the center system 1 manages the version of the terminal 6, the service server 2 can provide a service without being conscious of the process associated with the version change of the terminal 6. When logging out, the terminal 6 transmits a logout request to the request receiving unit 12 (step S4), and in response, the request receiving unit 12 transmits a logout notification to the terminal 6 (step S5).
[0023]
Next, the service start / end operation will be described with reference to FIG. First, when receiving a service, a service start request is transmitted from the terminal 6 (step S11).
In response to this, the request receiving unit 12 checks whether the user requesting the service can use the service. Further, when the service to be started requires some kind of vehicle information uplink, the terminal 6 starts the vehicle information uplink upon reception of the service start notification (steps S12 and S13) (steps S14 and S15). . Depending on the service that does not require the vehicle information uplink, the start / end procedure may not be required. Further, when a plurality of services are activated, if at least one service that requires an uplink is activated, even if the center system 1 receives a termination request for another service, the center system 1 may receive an uplink request. Does not terminate.
[0024]
As shown in FIG. 5A, the information of the currently received service and available services is managed by associating the service server ID (SS_ID) with the user ID in the database at the start of the service. Whether the service to be started requires the vehicle information uplink is determined by associating the service server ID (SS_ID) with the presence or absence of the uplink in a database as shown in FIG. 5B. And make a judgment by referring to this.
[0025]
At the end of the service, similarly, a service end request is transmitted (step S17), and upon receiving the service end notification (steps S18, S19), the vehicle information uplink (steps S20, S21) is stopped, and the service end notification is transmitted to the terminal 6. (Step S22).
[0026]
Next, a page access operation of the service server (SS) 2 will be described with reference to FIG. The service server 2 holds a service-specific screen such as an operation screen for setting information specific to a service. For example, there is a personal profile information operation screen such as a genre setting of distribution information content. The terminal 6 requests the page of the service server from the SS page access unit 13 of the terminal GW layer 11 (step S31). The SS page access unit 13 requests a page from the service server 2 on behalf of the terminal 6 (step S32), and receives the result (step S33). Then, the SS page access unit receives the terminal-specific information from the terminal management database 15, performs conversion according to the terminal 6, and returns a page response to the terminal 6 (step S34).
[0027]
Next, an information distribution operation will be described with reference to FIG. The distribution management unit 22 of the service server 2 transmits the distribution content to the distribution reception unit 17 of the service server GW layer 16 (Step S41). The distribution receiving unit 17 of the service server GW layer 16 authenticates whether or not the server is a server that can use the center system 1 based on the service server address of the transmission source in order to prevent unauthorized access. If the authentication is successful, the distribution receiving unit 17 transmits a content reception notification to the distribution management unit 22 (step S42).
[0028]
Next, the distribution receiving unit 17 performs a filtering process by matching the user's preference and the service, and then makes a distribution request to the distribution control unit 14 (steps S43 and S44). In response to this, the distribution control unit 14 converts the format of the received distribution information according to the terminal type, and performs push distribution to the terminal 6 (step S45).
Then, since the service server 2 performs transmission confirmation, the terminal 6 sends a push distribution reception confirmation to the distribution control unit 14 of the terminal GW layer 11 (step S46), and is transferred to the service server 2 (step S47). , S48).
[0029]
Next, an operation when a distribution request is received from the information provider terminal 7 will be described with reference to FIG. This is an operation in a push information distribution in a case where a distribution request from the external information provider terminal 7 triggers and a push distribution to the terminal 6 occurs.
When the registration receiving unit 23 of the service server 2 receives a mail distribution request transmitted from the information provider terminal 7 by the mail sender (information provider) like an electronic mail (step S51), the registration receiving unit 23 distributes the request. Notification is sent to the management unit 22, and information distribution occurs.
Since the information distribution operation is as described above, the description is omitted here. In addition to e-mail, it is also possible to use such as broadcasting at the time of advertisement registration, such as supermarket sale information, or broadcasting to nearby vehicles at the time of accident information registration.
[0030]
Next, an operation when vehicle information is received from the terminal 6 provided in the vehicle will be described with reference to FIG. This is an operation in a case where, in the push information distribution, the vehicle information that the terminal 6 automatically uplinks is used as a trigger, and the push distribution to the terminal 6 occurs. For example, as an example of a service in which location information is uplinked and nearby restaurant information is distributed, the request receiving unit 12 receives the uplinked vehicle information (here, location information) from the terminal 6 (step S61). Notifies the service management unit 21 of the service server 2 of the vehicle ID (or the user ID) and the vehicle information (Step S62). Upon receiving the vehicle information, the service management unit 21 notifies the terminal 6 that the vehicle information has been received via the request receiving unit 12 (steps S63 and S64).
[0031]
When there are a plurality of service servers 2, the request receiving unit 23 refers to the database, extracts the service server 2 of the service currently executed by the terminal 6 that has been uplinked, and notifies only the service server 2. The service management unit 21 compares the location information with the content managed by itself, picks up the content, and starts the information distribution process. Since the information distribution operation is as described above, the description is omitted here.
[0032]
Next, an operation when the terminal 6 starts a plurality of push distribution services simultaneously will be described. When the terminal 6 activates a plurality of push distribution services at the same time, each service server 2 transmits a distribution request to the distribution receiving unit 17 of the service server GW layer 16 at a unique timing. In response to this, the distribution receiving unit 17 receives and buffers distribution requests from other service servers 2 for a predetermined time (distribution reception time) after first receiving a distribution request. Then, when the distribution reception time ends, the information received within the period is filtered (for example, only the information that the user has declared to receive the information of the transmission source service server 2 is left), and the remaining content is deleted. They are arranged sequentially and transmitted to the terminal GW layer 11. The distribution control unit 14 of the terminal GW layer 11 transmits the transmission result to the terminal 6 to the service server 2 of the content transmission source from the information reception message received from the terminal 6.
[0033]
As described above, it is possible to receive a plurality of push services at the same time without changing the communication link of the terminal 6. In addition, the companies that provide the push service can plan their own push schedules and request the center system 1. In addition, by having functions such as user authentication in the center system 1, a service provider can leave the function of user management to the center system 1.
