For example, if the ticket number of the parking lot is used as a password, differentiated information can be provided to the parking lot user.

The following processing is realized by an information providing program executed by each component (computer) in FIG.

In step S1, when a user requests the PHS terminal 2 to transmit a radio packet in the area, the PHS terminal 2 and the base station 1 establish a radio channel for packets. In the following step S3, the PHS terminal 2 transmits the called number to the authentication center 12 by the user's dial operation. In the following step S5, the authentication center 12
Translates the transmitted called number, and determines whether or not the translated call number is a communication call to the content providing server 3 based on whether or not the translated called number matches the number of the content providing server 3 stored in advance. In step S5, the authentication center 12 translates the calling number, and determines whether or not information can be provided based on whether the translated calling number matches any of the previously stored calling numbers. In step S7, the authentication center 12
The determination result at step 5 is returned to the base station 1. Next, in step S9, the base station 1 determines whether or not information can be provided based on the determination result from the authentication center 12, and performs the following processing. Specifically, when the determination result from the authentication center 12 indicates that information cannot be provided (NO), the communication call from the PHS terminal 2 is disconnected. Therefore, the inconvenience of dialing outside can be prevented.

On the other hand, the judgment result from the authentication center 12 is
In the case of indicating that information can be provided (YES), the base station 1 itself is called without disconnecting the communication call, and then X. The following processing is performed according to the 25-packet communication procedure.

That is, in step S11, the base station 1 and the content providing server 3 establish a packet L2 / L3. In step S13, the base station 1 responds to the PHS terminal 2 that the wireless packet L3 has been established.

Thereafter, if necessary, step S15
Then, the content providing server 3 checks the password input from the PHS terminal 2 with a password stored in advance to determine whether the service is available. If the passwords match and the user is authenticated, the content providing server 3 performs IP communication with the PHS terminal 2 in the following step S17. In this IP communication, for example, information in an area stored in the content providing server 3 and updated as needed is provided to the PHS terminal 2. More specifically, such information has a format in which a link for acquiring other information is embedded, and related information can be acquired from the content providing server 3 one after another. .

When the user who wants to end the information acquisition performs a predetermined operation on the PHS terminal 2, the following operation is performed.

First, in step S19, the PHS terminal 2 requests the base station 1 to release the radio packet L3. In step S21, the packet L2 / L3 between the base station 1 and the content providing server 3 is released. Is done. Further, in step S23, the base station 1 notifies the charging center 13 of charging information relating to the communication in step S17. The billing information in this case may be, for example, information corresponding to the communication time, or may be information corresponding to the amount of data transmitted.

As described above, according to the method for providing information to the PHS terminal in the service area according to the embodiment of the present invention, the authentication center 12 is connected to the PHS terminal within the service area for any communication call requested to be received. First step of determining whether the call is from the PHS terminal 2 to the content providing server 3 accommodated in the base station 1 in the area, and the authentication center 1
2 notifies the base station 1 of the determination result of the first step to the base station 1 and the second step of making the base station 1 itself call a communication call based on the determination result that the base station 1 is a call to the content providing server 3. Since the content providing server 3 includes a third stage and a fourth stage of providing information from the content providing server 3 to the PHS terminal 2 in communication in a communication call in which the content providing server 3 receives a call, the content accommodated in the base station is provided. Provision server 3
And information need not be provided via an IP network outside the area.

As a result, it is not necessary to pay a communication fee to the provider, so that the communication cost can be reduced. Further, since access to the outside is restricted, security can be enhanced.

The authentication center 12 makes the first-stage determination based on the pre-stored destination number (that is, identification information) of the content providing server 3, and is used only within the service area. Since the calling number (identification information) stored in advance for the PHS terminal 2 is determined based on the calling number (identification information), a process of inquiring such identification information to another server one by one becomes unnecessary.

Since the base station 1 disconnects the communication call based on the result of the determination that the call is not to the content providing server 3, it is possible to prevent inconveniences such as calling out of the area.

Further, the content providing server 3 authenticates with a password when providing information in the fourth stage, so that it is possible to provide differentiated information to a specific user. Note that the user authentication using such a password can be performed in the authentication center 12 or the base station 1, but is preferably performed in the content providing server 3 in consideration of security.

Since the content providing server 3 provides the information in the fourth stage by IP communication,
Various contents created on the premise of IP communication can be used for providing information in the area.

Also, since the base station 1 charges for information provision, it is possible to obtain a legitimate information provision fee from a company that provides contents.

As another application example, the content providing server 3 is a server that can make a reservation, and the user provides a PHS.
If a reservation is made from the terminal 2 to the reservation server and the reservation is arranged in the queue of the reserved amusement, the order is advanced with time, and the service can be used even if the call is not made before the start.

In addition, a questionnaire conventionally performed by a companion of a venue by listening to the impressions of visitors can be collected by using the content providing server.

Further, by supporting wireless packet communication, multiplex communication of wireless channels becomes possible, and it is possible to cope with an increase in IP traffic concentrated per base station.

If base stations are connected to each other, flexible equipment investment according to traffic becomes possible. In addition, since PHS suitable for data communication is used as infrastructure,
Economical equipment costs can be achieved.

The program for providing information to the PHS terminal for executing the processing described above includes a semiconductor memory,
It can be widely distributed by being recorded on a computer-readable recording medium such as a magnetic disk, an optical disk, a magneto-optical disk, or a magnetic tape, or transmitted via a communication network such as the Internet.

[0053]

As described above, according to the present invention,
Since information can be provided from the content providing server accommodated in the base station to the PHS terminals in the area, there is no need to provide information via an IP network outside the area. As a result, it is possible to reduce communication costs and enhance security.
