Abstract

The present disclosure relates to an apparatus and a method for controlling Transmission Control Protocol (TCP) connection close to improve a battery life time of a client such as a smart phone in a wireless communication system are provided. A method of operating a client in a wireless communication system includes determining a data transfer inactivity time of at least one of TCP connections, and closing the at least one of TCP connections at the data transfer inactivity time.

Claims

1. A method of operating a client in a wireless communication system, comprising:

determining a guard time period for at least one transmission control protocol (TCP) connection based on a first time period and a second time period; and

closing the at least one TCP connection in response to an expiration of the guard time period,

wherein;

the first time period is a period of time from a transmission time of a request to a reception time of a response to the request, and

the second time period is a period of time from the reception time of the response to a transmission time of a next request.

2. The method of claim 1, wherein the guard period time is ahead of a time for a server-initiated TCP connection close.

3. The method of claim 2, wherein the server-initiated TCP connection close is performed in response to a message indicating a close of the at least one TCP connection received from a server.

7. The method of claim 1, wherein the request and the next request is transmitted from the client to a server through the at least one TCP connection, and the response is transmitted from the server to the client through the at least one TCP connection.

4. An apparatus of a client in a wireless communication system, comprising:

a controller configured to;

determine a guard time period for at least one transmission control protocol (TCP) connection based on a first time period and a second time period; and

close the at least one TCP connection in response to an expiration of the guard time period,

wherein;

the first time period is a period of time from a transmission time of a request to a reception time of a response to the request, and

the second time period is a period of time from the reception time of the response to a transmission time of a next request.

5. The apparatus of claim 4, wherein the guard period time is ahead of a time for a server-initiated TCP connection close.

6. The apparatus of claim 5, wherein the server-initiated TCP connection close is performed in response to a message indicating a close of the at least one TCP connection received from a server.

8. The apparatus of claim 4, wherein the request and the next request is transmitted from the client to a server through the at least one TCP connection, and the response is transmitted from the server to the client through the at least one TCP connection.
