Abstract

When changes occur in an environment of the service user terminal, a network operator terminal acquires hashed environment information indicative of the changes from the service user terminal. The network operator terminal sends the hashed environment information to an environment management authority terminal. The environment management authority terminal calculates an evaluation value based on the hashed environment information and transmits the evaluation value to a network operator terminal. The network operator terminal transmits status change information to the service provider terminal. The service provider terminal updates information about the user information previously stored and decides whether to provide the service to the service user terminal based on the updated information.

Claims

1. A computer-readable recording medium that stores therein a computer program that implements on a-control terminal a method of controlling whether to provide a service to a user terminal from a provider terminal, the computer program causing the control terminal to execute:

acquiring user information indicative of changes in the environment of the user terminal; and

transmitting the user information to the provider terminal whereby the provider terminal decides based on the user information whether to provide the service to the user terminal.

2. The computer-readable recording medium according to claim 1, wherein the acquiring includes periodically acquiring the information.

3. The computer-readable recording medium according to claim 1, wherein the acquiring includes acquiring the information upon receiving a request from other device.

4. The computer-readable recording medium according to claim 1, further comprising storing, after the acquiring and before the transmitting, the information in a storage unit.

5. A method of controlling with a control terminal whether to provide a service to a user terminal from a provider terminal, the method including the control terminal performing:

acquiring user information indicative of changes in the environment of the user terminal; and

transmitting the user information to the provider terminal whereby the provider terminal decides based on the user information whether to provide the service to the user terminal.

6. The method according to claim 5, wherein the acquiring includes periodically acquiring the information.

7. The method according to claim 5, wherein the acquiring includes acquiring the information upon receiving a request from other device.

8. The method according to claim 5, further comprising storing, after the acquiring and before the transmitting, the information in a storage unit.

9. A service controlling system including a user terminal, a provider terminal, and a control terminal, wherein the control terminal controls whether to provide a service to a user terminal from a provider terminal, the control terminal comprising:

an acquiring unit that acquires user information indicative of changes in the environment of the user terminal;

a calculating unit that calculates a user evaluation value based on the user information; and

a controlling unit that controls provision of the service to the user terminal from the provider terminal based on the user evaluation value.

10. The service controlling system according to claim 9, wherein the acquiring unit periodically acquires the user information.

11. The service controlling system according to claim 9, wherein the acquiring unit acquires the user information upon receiving a request from other device.

12. The service controlling system according to claim 9, wherein the acquiring unit acquires provider information indicative of changes in environment of the provider terminal,

the calculating unit calculates a provider evaluation value based on the second information, and

the controlling unit controls provision of the service to the user terminal from the provider terminal based on the user evaluation value and the provider evaluation value.

13. The service controlling system according to claim 9, further comprising a storage unit that stores therein the user information.
