Abstract

A method of connecting to a network by a terminal in a communication system, the communication system including the terminal, one or more access points, and a network controller controlling the one or more access points is provided. The method includes establishing a connection with a first access point, setting and storing wake-up information, configured to selectively transceive with the first access point, in the first access point and the network controller, performing hand off to a second access point connected to the network controller, and selectively transceiving data with the second access point based on the wake-up information set and stored in the network controller.

Claims

1. A method of connecting to a network by a terminal in a communication system, the communication system including the terminal, one or more access points, and a network controller controlling the one or more access points, the method comprising:

establishing a connection with a first access point;

setting and storing wake-up information, configured to selectively transceive with the first access point, in the first access point and the network controller;

performing hand off to a second access point connected to the network controller; and

selectively transceiving data with the second access point based on the wake-up information set and stored in the network controller.

2. The method of claim 1, wherein the wake-up information includes a type of data to be selectively transceived, wake-up section information indicating an operation section of an operation/dormant mode, and a wake-up information identifier identifying a wake-up information setting.

3. The method of claim 2, wherein the setting and storing of the wake-up information in the first access point and the network controller includes making a request for setting the type of data and the wake-up section information in the first access point, and storing the wake-up information identifier contained in the wake-up information in the first access point.

4. The method of claim 2, wherein the setting and storing of the wake-up information in the first access point and the network controller includes making a request for storing the type of data, the wake-up section information, and the wake-up information identifier in the network controller.

5. The method of claim 2, wherein the performing of the hand off to the second access point includes:

transmitting a message making a request for authentication of the hand off including the wake-up information identifier to the second access point so that the second access point identifies validity of the wake-up information setting with the network controller through the wake-up information identifier; and

receiving a result of the request for the authentication of the hand off and a result of the wake-up information setting from the second access point.

6. A method of connecting to a network by a first access point in a communication system, the communication system including terminals, one or more access points, and a network controller controlling the one or more access points, the method comprising:

establishing a connection with a first terminal;

receiving wake-up information configured to selectively transceive data from the first terminal;

setting the wake-up information; and

storing the wake-up information in the network controller.

7. The method of claim 6, wherein the wake-up information includes a type of data to be selectively transceived, wake-up section information indicating an operation section of an operation/dormant mode, and a wake-up information identifier identifying a wake-up information setting.

8. The method of claim 7, wherein storing the wake-up information in the network controller includes making a request for storing the type of data, the wake-up section information, and the wake-up information identifier in the network controller.

9. The method of claim 6, further comprising:

performing hand off with a second terminal connected to a second access point connected with the network controller; and

selectively transceiving data with the second access point based on wake-up information related to the second terminal stored in the network controller.

10. The method of claim 9, wherein the performing of the hand off further comprises:

receiving a message making a request for authentication of the hand off including the wake-up information identifier from the second terminal so as to identify validity of the wake-up information setting with the network controller through a wake-up information identifier for the second terminal;

making a request for wake-up information corresponding to the wake-up information identifier to the network controller; and

setting the type of data and the wake-up section information contained in the wake-up information.

11. A terminal device connected with one or more access points in a communication system, the communication system including the one or more access points and a network controller controlling the one or more access points, the terminal device comprising:

a controller configured to control a connection with a first access point, to control setting and storing wake-up information, configured to selectively transceive with the first access point, in the first access point and the network controller, to control hand off to a second access point connected to the network controller, and to control selective transmission/reception of data with the second access point based on the wake-up information set and stored in the network controller; and

a data transceiver configured to transmit the data provided from the controller, and to receive data from the outside and provide the received data to the controller under control of the controller.

12. The terminal device of claim 11, wherein the wake-up information includes a type of data to be selectively transceived, wake-up section information indicating an operation section of an operation/dormant mode, and a wake-up information identifier identifying a wake-up information setting.

13. The terminal device of claim 12, wherein the controller is further configured to set the type of the data and the wake-up section information in the first access point, to generate a message making a request for storing the wake-up information identifier contained in the wake-up information in the first access point, and to transmit the generated message to the first access point.

14. The terminal device of claim 12, wherein the controller is further configured to make a request for storing the type of the data, the wake-up section information, and the wake-up information identifier in the network controller.

15. The terminal device of claim 12, wherein the controller is further configured to transmit a message making a request for authentication of the hand off including the wake-up information identifier to the second access point so that the second access point identifies validity of the wake-up information setting with the network controller through the wake-up information identifier.

16. An access point included in a communication system including terminals, one or more access points, and a network controller for controlling the one or more access points, the access point comprising:

a processor configured to establish a connection with a first terminal, to receive wake-up information configured to selectively transceive data from the first terminal, to set the wake-up information, and to store the wake-up information in the network controller,

a data transceiver configured to process transmission/reception of data with the first terminal and the network controller; and

a memory configured to store the wake-up information.

17. The access point of claim 16, wherein the wake-up information includes a type of data to be selectively transceived, wake-up section information indicating an operation section of an operation/dormant mode, and a wake-up information identifier identifying a wake-up information setting.

18. The access point of claim 16, wherein the processor is further configured to perform a hand off with a second terminal connected to a second access point connected to the network controller, and selectively transceives the data with the second terminal based on wake-up information related to the second terminal stored in the network controller.

19. The access point of claim 18, wherein the processor is further configured to receive a message making a request for authentication of the hand off including the wake-up information identifier so as to identify a validity of the wake-up information setting through the wake-up information identifier for the second terminal with the network controller,

to receive wake-up information corresponding to the wake-up information identifier with the network controller, and

to set a type of data and wake-up section information contained in the wake-up information.
