A plurality of base stations 103 are connected to the CATV server 10
5, the base stations 103 are generally located at different positions. Therefore,
From the position of the base station 103, it is possible to know the approximate position where the terminal 102 is currently located. For example, each base station 103 can be provided with traffic information and weather forecast around the base station 103, and stores, held events, and advertisement information around the base station 103 in association with each other.

The CATV server 105 according to the present embodiment has the same basic configuration as the CATV server 105 according to the above-described embodiment, but includes a selection unit 508 and differs in the following points, which can be realized.

[0167] The second receiving unit 506 includes a plurality of base stations 10.
The request information is received from any one of (3).

The selecting section 508 selects a response that provides a service associated with the base station 103 that has transmitted the request information received by the second receiving section 506.

[0169] Second transmitting section 507 transmits the selected response to base station 103 which has transmitted the request information received by second receiving section 506.

The correspondence between the base station 103 and the type of service to be provided is registered in a database in the CATV server 105, and the selection unit 508 can inquire of this.

(Fourth Embodiment) FIG. 9 shows the C
It is a schematic diagram which shows the schematic structure of 4th Embodiment of the wireless provision system of ATV service.

In the above embodiment, the user identification information is centrally managed nationwide. However, for example, a method similar to the roaming service employed in mobile phones and PHSs can be used. That is, the user identification information is
The roaming service of the CATV service is performed after registration in the database of the authentication server 104 provided in each TV company.

The user identification information is configured to include information for identifying a CATV company. Thereby, the authentication server 104 of each company determines whether the validity of the user identification information can be determined only by the information of the database managed by itself or whether it is necessary to inquire the database of the authentication server 104 of another company. Can be.

The user identification information of a user of another company that has been determined valid after being queried is stored in its database.
A predetermined expiration date can be set and temporarily stored. In this way, by caching the user identification information determined to be valid, it is possible to reduce the number of inquiries between the authentication servers of each company, and to achieve a high-speed response.

(Fifth Embodiment) In the above embodiment,
The user identification information is obtained by recording the user identification information on a user identification information recording medium such as a magnetic card. For example, a password is assigned to each user, a keyboard is arranged on the terminal 102, and the password is assigned by the keyboard. You may input it. However, if the password is leaked to another person, the CATV service may be provided to an unauthorized person.

Therefore, information unique to each user, for example,
User authentication using physical information such as a fingerprint, voiceprint, and iris shape can also be performed. In this case, the fingerprint, voiceprint, shape of the iris, and the like become the user identification information, and the authentication server 10
Reference numeral 4 manages the characteristic parameters of these shapes of each user as a database, and determines whether or not the user has the right to use.
