Abstract

A method and device for controlling an ad-hoc network using a CPNS entity having a secure element (SE) in a CPNS enabler are discussed. According to an embodiment, the invention provides a method including receiving ad-hoc network information and SE information from each of the CPNS entities; designating one of the CPNS entities to be an ad-hoc network controller for an ad-hoc network based on the ad-hoc network information and the SE information; transmitting a command to perform a configuration of the ad-hoc network, information about the designated ad-hoc network controller, and service constraint information, to the designated ad-hoc network controller; and receiving service use information prepared based on the service provided in the ad-hoc network from the designated ad-hoc network controller.

Claims

1. A mobile terminal for controlling an ad-hoc network in a converged personal network service (CPNS) enabler, the CPNS enabler including a CPNS server and a plurality of CPNS entities, the mobile terminal being one of the CPNS entities, the mobile terminal comprising:

a receiver/transmitter unit;

a memory unit configured to store information which enables the mobile terminal to manage and carry out ad-hoc network operations on behalf of the CPNS server without a connection to the CPNS server, and ad-hoc network service use information dedicated to be used when the mobile terminal forms an ad-hoc network while the connection between the mobile terminal and the CPNS server is broken; and

a processor configured to;

receive a command to perform a configuration of an ad-hoc network, and service constraint information, from the CPNS server,

wherein the command instructs the mobile terminal to form the ad-hoc network with one or more other CPNS entities;

perform the configuration of the ad-hoc network according to the command, to have direct connections with each of the other CPNS entities;

allow the mobile terminal and the other CPNS entities to communicate with each other in the ad-hoc network using the dedicated ad-hoc network service use, wherein the communication among the mobile terminal and the other CPNS entities in the ad-hoc network using the dedicated ad-hoc network service use information is allowed for a quantity of data and the dedicated ad-hoc network service use information is updated when the connection between the mobile terminal and the CPNS server is broken; and

upload the updated ad-hoc network service use information to the CPNS server if the connection between the mobile terminal and the CPNS server is restored.

2. The mobile terminal of claim 1, wherein the processor is further configured to:

manage and control alone the ad-hoc network using the dedicated ad-hoc network service use information until the CPNS server reloads to replace with the dedicated ad-hoc network service use information into the memory unit.

3. The mobile terminal of claim 1, wherein the service constraint information includes at least one of prepayment information and rights information for the at least one service provided in the ad-hoc network.

4. The mobile terminal of claim 1, wherein the memory unit includes at least one of a subscriber identity module (SIM) card, a secure digital (SD) card, an external card, or an internal card.

5. A mobile terminal for controlling an ad-hoc network in a converged personal network service (CPNS) enabler, the CPNS enabler including a CPNS server and a plurality of CPNS entities, the mobile terminal being one of the CPNS entities, the mobile terminal comprising:

a receiver/transmitter unit;

a memory unit configured to store information which enables the mobile terminal to manage and carry out ad-hoc network operations on behalf of the CPNS server without a connection to the CPNS server, and ad-hoc network service use information dedicated to be used when the mobile terminal forms an ad-hoc network while the connection between the mobile terminal and the CPNS server is broken; and

a processor configured to;

receive a command to perform a configuration of an ad-hoc network, and service constraint information, from the CPNS server,

wherein the command instructs the mobile terminal to form the ad-hoc network with one or more other CPNS entities;

perform the configuration of the ad-hoc network according to the command, to have direct connections with each of the other CPNS entities;

allow the mobile terminal and the other CPNS entities to communicate with each other in the ad-hoc network using the dedicated ad-hoc network service use information, wherein the communication among the mobile terminal and the other CPNS entities in the ad-hoc network using the dedicated ad-hoc network service use information is allowed only during 5 minutes and the dedicated ad-hoc network service use information is updated when the connection between the mobile terminal and the CPNS server is broken; and

upload the updated ad-hoc network service use information to the CPNS server if the connection between the mobile terminal and the CPNS server is restored.

6. The mobile terminal of claim 5, wherein the processor is further configured to:

manage and control alone the ad-hoc network using the dedicated ad-hoc network service use information until the CPNS server reloads to replace with the dedicated ad-hoc network service use information into the memory unit.

7. The mobile terminal of claim 5, wherein the service constraint information includes at least one of prepayment information and rights information for the at least one service provided in the ad-hoc network.

8. The mobile terminal of claim 5, wherein the memory unit includes at least one of a subscriber identity module (SIM) card, a secure digital (SD) card, an external card, or an internal card.
