Abstract

The present invention relates to a base station, and to a terminal connection method for the base station. The terminal connection method for the base station according to one embodiment of the present invention comprises: a step of connecting to a terminal; an information extracting step of extracting information for determining a timeout value of the connection of the terminal when the connection to the terminal is completed; and a time-out setting step of setting a time-out value of the terminal according to the extracted information. According to the one embodiment of the present invention, the base station may efficiently utilize resources and overhead expenses for connection setup may be reduced.

Claims

1. A terminal connection method of a base station, the method comprising:

extracting, if the terminal is connected, information on a traffic pattern of previous transmission for use in determining a timeout value of a connection of the terminal;

configuring the timeout value of the terminal according to the extracted information;

providing the terminal with packet communication service; and

releasing, if the timeout value expires without traffic for the terminal in providing the packet communication service, the connection with the terminal.

2. The method of claim 1, wherein the extracting of the information comprises:

extracting a time interval between two recent connection establishments between the terminal and the base station; and

extracting a number of bursts or a number of packets during the time interval.

3. The method of claim 2, wherein the configuring of the timeout value comprises:

extracting a value obtained by dividing the number of bursts or packets by the extracted time interval as a degree of activity; and

configuring the timeout value according to the degree of activity.

4. The method of claim 2, wherein the configuring of the timeout value comprises:

extracting an old timeout value configured lastly before current time;

extracting a value obtained by dividing the number of bursts or packets by the old time interval as a degree of activity; and

configuring the timeout value according to the old timeout value and the degree of activity.

5. The method of claim 4, wherein the configuring of the timeout value comprises calculating the timeout value T_new according to the following equation:

T_new=α

T_prev+β

T_current(here, α

+β

=1)

where α and

β

denote weights, T_prev denotes the old timeout value, T_current denotes the timeout value extracted according to the degreed of activity.

6. The method of claim 1, wherein the extracting of the information comprises:

receiving Quality of Service (QoS) for the connection of the terminal; and

extracting the QoS information as the information for determining the timeout value.

7. The method of claim 1, wherein the extracting of the information comprises:

receiving information necessary for calculating the timeout value of the terminal from the terminal; and

extracting the received information as the information for determining the timeout value.

8. A base station to which a terminal connects, the base station comprising:

a communication unit configured to transmit and receive a signal; and

a control unit configured to;

control to extract if the terminal is connected, information on a traffic pattern of previous transmission for use in determining a timeout value of a connection of the terminal and configures the timeout value of the terminal according to the extracted information,

configure the timeout value of the terminal according to the extracted information, to provide the terminal with packet communication service, and

release, if the timeout value expires without traffic for the terminal in providing the packet communication service, the connection with the terminal.

9. The base station of claim 8, wherein the controller is further configured to control to:

extract a time interval between two recent connection establishments between the terminal and the base station, and

extract a number of bursts or a number of packets during the time interval.

10. The base station of claim 9, wherein the controller is further configured to:

control to extract a value obtained by dividing the number of bursts or packets by the extracted time interval as a degree of activity, and

configure the timeout value according to the degree of activity.

11. The base station of claim 9, wherein the control unit is further configured to:

extract an old timeout value configured lastly before current time,

extract a value obtained by dividing the number of bursts or packets by the old time interval as a degree of activity, and

configure the timeout value according to the old timeout value and the degree of activity.

12. The base station of claim 11, wherein the timer calculates the timeout value T_new according to the following equation:

T_new=α

T_prev+β

T_current(here, α

+β

=1)

where α and

β

denote weights, T_prev denotes the old timeout value, T_current denotes the timeout value extracted according to the degreed of activity.

13. The base station of claim 8, wherein the control unit is further configured to:

receive Quality of Service (QoS) for the connection of the terminal, and

extract the QoS information as the information for determining the timeout value.
