Abstract

A connection close-related packet transmission method and apparatus is provided for improving power saving efficiency of a power-constrained mobile terminal. The connection close-related packet transmission method includes establishing a radio connection with a server; determining whether a preconfigured connection close timeout elapses without connection activity after the connection establishment; buffering, when the connection close timeout elapses, a connection close-related packet; and transmitting, when another packet transmission is predicted, the connection-related packet to the server. The connection close-related packet transmission method and apparatus is advantageous in power saving efficiency of a power-constrained mobile terminal.

Claims

1. A connection close-related packet transmission method of a terminal, the method comprising:

establishing a radio connection with a server;

determining whether a preconfigured connection close timeout elapses without connection activity after establishing the connection;

buffering, when the connection close timeout elapses, a connection close-related packet; and

transmitting, when another packet transmission is predicted, the connection-related packet to the server.

2. The method of claim 1, further comprising transmitting, when a preconfigured buffering timeout elapses without transmission of the connection close-related packet after buffering the connection close-related packet, the connection close-related packet to the server.

3. The method of claim 2, wherein the another packet is a data packet.

4. The method of claim 2, wherein the terminal comprises a radio communication unit for performing radio communication.

5. The method of claim 4, further comprising turning off, when a preconfigured inactivity timeout elapses without data communication through the radio communication unit, power to the radio communication unit.

6. The method of claim 5, wherein the inactivity timeout is set to a value less than the buffering timeout.

7. The method of claim 1, further comprising transmitting, when a number of buffered connection close-related packets is greater than a predetermined threshold value, the buffered connection close-related packets to the server.

8. The method of claim 2, wherein the connection is a Transmission Control Protocol (TCP) connection, and the connection close-related packet is TCP Finish (FIN) packet.

9. The method of claim 8, wherein transmitting comprises sending, when a TCP Synchronization (SYN) packet transmission is required for a new connection, the buffered FIN packet.

10. The method of claim 2, wherein establishing the connection comprises establishing one of Transport Layer Security (TLS) connection and Security Socket Layer (SSL) connection with the server, and the connection close-related packet is a close_notify alert message packet.

11. A connection close-related packet transmission apparatus for mobile communication, the apparatus comprising:

a radio communication unit which establishes a radio connection with a server;

a connection close timer which determines whether a preconfigured connection close timeout elapses without connection activity after the connection establishment; and

a control unit which controls to buffer, when the connection close timeout elapses, a connection close-related packet,

wherein the radio communication unit transmits, when another packet transmission is predicted, the connection-related packet to the server.

12. The apparatus of claim 11, wherein the radio communication unit transmits, when a preconfigured buffering timeout elapses without transmission of the connection close-related packet after buffering the connection close-related packet, the connection close-related packet to the server.

13. The apparatus of claim 12, wherein the another packet is a data packet.

14. The apparatus of claim 12, wherein the control unit turns off, when a preconfigured inactivity timeout elapses without data communication through the radio communication unit, power to the radio communication unit.

15. The apparatus of claim 14, wherein the inactivity timeout is set to a value less than the buffering timeout.

16. The apparatus of claim 11, wherein the radio communication unit transmits, when a number of buffered connection close-related packets is greater than a predetermined threshold value, the buffered connection close-related packets to the server.

17. The apparatus of claim 12, wherein the connection is a Transmission Control Protocol (TCP) connection, and the connection close-related packet is TCP Finish (FIN) packet.

18. The apparatus of claim 17, wherein the radio communication unit transmits, when a TCP Synchronization (SYN) packet transmission is required for a new connection, the buffered FIN packet.

19. The apparatus of claim 12, wherein the radio communication unit establishes one of Transport Layer Security (TLS) connection and Security Socket Layer (SSL) connection with the server, and the connection close-related packet is a close_notify alert message packet.
