Abstract

An activation instructing portion to instruct an activation instruction to a communications module and a core module, when a receiver portion receives a activation signal, wherein upon reception of an activation instruction while in a halt mode, the core module switches from the halt mode to an operational mode, upon reception of the activation instruction while in a halt mode, the communications module switches from the halt mode to an operational mode, and sends a reception completion signal after switching to the operational mode, and a period of time needed for the communications module to switch to the operational mode after receiving the activation signal is shorter than that of the core module.

Claims

1. A communications terminal comprising:

a receiver portion to receive an activation signal from an activation-requesting terminal;

a communications module to send a reception completion signal to the activation-requesting terminal;

a core module to provide a core function; and

an activation instructing portion to instruct an activation instruction to the communications module and the core module, when the receiver portion receives the activation signal,

wherein

upon reception of the activation instruction while in a halt mode, the core module switches from the halt mode to an operational mode,

upon reception of the activation instruction while in a halt mode, the communications module switches from the halt mode to an operational mode, and sends the reception completion signal after switching to the operational mode, and

a period of time needed for the communications module to switch to the operational mode after receiving the activation signal is shorter than that of the core module.

2. The terminal of claim 1,

wherein the reception completion signal includes an address assigned to the communication terminal.

3. The terminal of claim 1 further comprising,

a message holder portion to hold first information on the reception completion signal,

wherein the communications module sends the reception completion signal generated by the first information.

4. The terminal of claim 1,

wherein while in the halt mode, the communications module and the core module switches between a power ON state and a power OFF state, and

the activation instructing portion instructs the core module and the communications module to switch from the power OFF state to the power ON state.

5. The terminal of claim 1,

wherein after the core module switches to the operational mode, the communications module provides a network function for the core module.

6. The terminal of claim 5,

wherein the core module has a function for responding to a request, which is received from the activation-requesting terminal, using the network function of the communications module.

7. The terminal of claim 6,

wherein the communications module sends the reception completion signal which includes the address included in the activation signal.

8. The terminal of claim 7,

wherein the first information held in the message holder portion includes information on an address assigned to an interface of the communications module.

9. The terminal of claim 8,

wherein the communications module uses a wireless LAN management frame to send the reception completion signal.

10. The terminal of claim 9,

wherein the first information held in the message holder portion is information on a time needed for the core module to switch to the operational mode after the beginning of the activation.

11. A computer readable medium storing a communications program comprising:

a receiver function to receive an activation signal from an activation-requesting terminal;

a communications module function to send a reception completion signal to the activation-requesting terminal;

a core module function to provide a core function; and

an activation instructing function to instruct an activation instruction to the communications module function and the core module function, when the receiver function receives the activation signal,

wherein

upon reception of the activation instruction while in a halt mode, the core module function switches from the halt mode to an operational mode,

upon reception of the activation instruction while in a halt mode, the communications module function switches from the halt mode to an operational mode, and sends the reception completion signal after switching to the operational mode, and

a period of time needed for the communications module function to switch to the operational mode after receiving the activation signal is shorter than that of the core module function.

12. The computer readable medium storing a communications program according to claim 11,

wherein the reception completion signal includes an address assigned to a communication terminal.

13. The computer readable medium storing a communications program according to claim 11 further comprising,

a message holder function to hold first information on the reception completion signal,

wherein the communications module function sends the reception completion signal generated by the first information.

14. The computer readable medium storing a communications program according to claim 13,

wherein while in the halt mode, the communications module function and the core module function switches between a power ON state and a power OFF state, and

the activation instructing function instructs the core module function and the communications module function to switch from the power OFF state to the power ON state.

15. The computer readable medium storing a communications program according to claim 11,

wherein after the core module function switches to the operational mode, the communications module function provides a network function for the core module.

16. The computer readable medium storing a communications program according to claim 15,

wherein the core module function has a function for responding to a request, which is received from the activation-requesting terminal, using the network function of the communications module function.

17. The computer readable medium storing a communications program according to claim 16,

wherein the communications module function sends the reception completion signal which includes the address included in the activation signal.

18. The computer readable medium storing a communications program according to claim 17,

wherein the first information held in the message holder function includes information on an address assigned to an interface of the communications module function.

19. The computer readable medium storing a communications program according to claim 18,

wherein the communications module function uses a wireless LAN management frame to send the reception completion signal.

20. The computer readable medium storing a communications program according to claim 19,

wherein the first information held in the message holder function is information on a time needed for the core module function to switch to the operational mode after the beginning of the activation.
